Release Notes for REALbasic 2.1.1 May 4, 2000 This release contains the following new features: • (68k) Declare Sub now recognizes short parameter type for 16- bit parameters for 68k • (Mac) FolderItem.SaveAsJPEG implemented • (Mac) Icons now exist for REALbasic database files and REALbasic project stationary • (Mac) Window property: MacWindowPtr As Integer • (Plugin API) Added REALinRuntime Plugin API call - Returns true if in runtime, false if in IDE • (Win32) Application icon added • (Win32) Contextual menu: added • (Win32) Drag and Drop: Files implemented on Win32. The Window control's dropEvent is the only one that is currently supported. You can work-around this limitation by obtaining the DropLeft and DropTop coordinates and figuring out which control is being dropped on manually. Note: DropWidth and DropHeight properties have no meaning in Win32 and will return 0 unless set by a REALbasic application using NewDragItem. • (Win32) Drag and drop: implemented. • (Win32) ExportPicture: implemented (but doesn't work) • (Win32) FolderItem: ExportPicture now works for Win32. Saves in all supported picture depths. QuickTime is REQUIRED. • (Win32) FolderItem: FolderItem.MoveFileTo implemented • (Win32) FolderItem: FolderItem.SaveAsJPEG implemented (but doesn't work) • (Win32) FolderItem: SaveAsJPEG now works for Win32. Saves in all supported picture depths. Appends '.jpg' to folderItem.name if '.jpg' or '.jpeg' not already present, truncates file to fit if necessary. QuickTime is REQUIRED. • (Win32) FolderItem: SaveAsPicture now works for Win32. Note: On Win32 saves a bitmap file (or .bmp file) rather than a 'PICT' file. Saves in all supported picture depths. Appends '.bmp' to folderItem.name if not already present, truncates file to fit if necessary. QuickTime is NOT REQUIRED. • (Win32) FolderItem: SelectFolder Completely rewritten for Win32. It now calls the standard folder selection dialog instead of the get file dialog. The new interface is much more intuitive. • (Win32) Keyboard: You can pass raw Win32 key codes to GetAsyncKeyDown. Here is how you do it, Add 1 to the raw keyCode and put it in the high word of the integer you are passing. Example: Keyboard.AsyncKeyDown((rawKeyCode + 1) * &hFFFF) Passing Mac Keycodes in the high word is currently identical to passing them in the low word. • (Win32) Listbox: Hierarchical listbox support added • (Win32) Menu: accelerators implemented • (Win32) Picture: NewPicture: 24bit pictures are supported (Win32 only). 2bit, and 32bit Device Independant Bitmaps (or DIBs) aren't supported by Windows. • (Win32) Picture: NewPicture: 2bit, and 32bit Device Independant Bitmaps (or DIBs) aren't supported by windows. REALbasic relies on this technology to provide pictures under Win32, consequently 2bit and 32bit pictures are not supported. To make your life easier, requests for these picture types results in the following conversions behind the scenes: 2bit -> 4bit, and 32bit -> 24bit. • (Win32) Picture: NewPicture: 4bit Win32 pictures now in color, uses Mac standard 16 color palette. • (Win32) Progress bars -- Indeterminate implemented • (Win32) QuickTime: Implemented QuickTime. New features include: MoviePlayer control, Movie Class, FolderItem.OpenAsMovie, FolderItem.CreateMovie, EditableMovie Class, QTTrack class, QTVideoTrack class, QTEffectSequence class, GetQTCrossFadeEffect method, GetQTSMPTEeffect method • (Win32) QuickTime: implemented. New features include: MoviePlayer control, Movie Class, FolderItem.OpenAsMovie, FolderItem.CreateMovie, EditableMovie Class, QTTrack class, QTVideoTrack class, QTEffectSequence class, GetQTCrossFadeEffect method, GetQTSMPTEeffect method • (Win32) QuickTime: Movies continue to play in the background when other programs or modal dialogs are in the foreground. • (Win32) QuickTime: OpenURLMovie: now works for Win32. • (Win32) Sound: implemented • (Win32) Sound: Note player implemented, problems on Windows NT • (Win32) SpriteSurface: implemented • (Win32) Windows: property WinHWND As Integer (r) • About box: "Register" button has been moved, and URL now provides visual feedback. • Build Application... now has a keyboard shortcut (Cmd-M) • Build Dialog: added Region Code selector • Build Dialog: The language popup in the Build Dialog is now more informative. The first item 'Default' now shows the name of the default 'Debug' Language in paranthesis following the word Default. e.g. Default (Spanish) • Build Progress dialog: and build process now threaded. Thread Manager is now required to use the IDE. • Code Editor: live scrolling enabled for IDE source code editor • Code Editor: Page-up and Page-down implemented in the IDE source editor. • compilation constants: Target68k, TargetPPC • Constants: RBVersion constant returns the major and minor version number (e.g., 2.11). • Constants: RBVersionString constant returns short RB version string (e.g. "2.1a28"). • Control property: MacControlHandle As Integer • Cursors: A pragma has been added to disable the automatic display of the wait cursor (or watch cursor). Use #pragma DisableAutoWaitCursor to disable the default behavior. The pragma can be placed anywhere in the code, and it will affect all of your code. • Database: class method Close • Database: now automatically closes when closing application, project. • DatabaseCursorField property: DateValue As Date (r/w) • DatabaseCursorField property: DoubleValue As Double (r/w) • DatabaseRecord: properties DoubleColumn As Double (r/w), DateColumn As Date (r/w) • Date: global function ParseDate(text As String, ByRef parsedDate As Date) As Boolean • Debugger: Variables of type "Single" can now be edited in the debugger. (Note that you still can't edit Doubles, however.) • DragItem properties: DropLeft As Integer (r), DropTop As Integer (r), DropWidth As Integer (r), DropHeight As Integer (r) • EditableMovie: methods DataSize(startTime as integer, durationTime As Integer) As Integer • EditableMovie: properties TimeScale As Integer (r/w), TimeValue As Integer (r/w), TimeDuration As Integer (r), UserData As QTUserData (r) • Folder Item: global function: GetTemporaryFolderItem As FolderItem • Folder Item: properties: MacVRefNum As Integer, MacDirID As Integer • Keyboard shortcut Redo added (Shift Cmd Z) • Listbox: properties ColumnAlignment(column As Integer) As Integer (r/w), CellAlignment(row As Integer, cell As Integer) As Integer (r/w), Values for the alignment properties are: 0 = default alignment, 1 = Left Alignment, 2 = Center Alignment, 3 = Right Alignment, 4 = Decimal Alignment (using the internationalized Decimal separator), ColumnAlignmentOffset(column As Integer) As Integer (r/w), CellAlignmentOffset(row As Integer, cell As Integer) As Integer (r/w), The alignment offset properties allow the positioning of the text to be adjusted (+right) • Menus: Item "Clear" in the menu "Edit" is now enabled for deleting project items. • Picture: property Mask As Picture (r) this allows you to access a 256-gray mask that controls the transparency of the picture • Project window: REALbasic now does much better finding files that have been dragged into the project window when the entire project is moved to another volume. In general it will find any in the same folder or a sub folder as the project. If for some reason REALbasic still can not find items dragged into the project the message in the find dialog is now a bit more descriptive. e.g. If it can't find the picture file 'wonderful' the new message that appears is "Where is the picture called 'wonderful'?" instead of "Where is wonderful?" • PushButton: method Push - Causes the push button to be visually pushed, as well as triggering the Action event • QuickTime: class QTGraphicsExporter: HasSettingsDialog As Boolean (r), RequestSettings As Boolean, DefaultExtension As String (r), SettingsDescription As String (r), DesiredTargetDataSize As Integer (r/w), CompressionQuality As Integer (r/w), OutputFileType As String (r/w), OutputFileCreator As String (r/w), SavePicture(location As Folder, image As Picture) As Boolean • QuickTime: class QTUserData: UserDataCount(udType As string) As Integer, GetUserData(udType As string, index As Integer, ByRef value As string) As Boolean, AddUserData(udType As string, value As string), RemoveUserData(udType As string, index As Integer), GetUserDataText(udType As string, index As Integer, ByRef value As string, region As Integer) As Boolean, SetUserDataText(udType As string, index As Integer, value As string, region As Integer) • QuickTime: global method: GetQTGraphicsExporter(format as string) As QTGraphicsExporter • QuickTime: Movie property MovieHandle As Integer • QuickTime: MoviePlayer property QTMovieController As Integer (r) • QuickTime: QTTrack methods: DataSize(startTime as integer, durationTime As Integer) As Integer (r) • QuickTime: QTTrack properties: TimeScale As Integer (r/w), TimeDuration As Integer (r), TrackID As Integer (r) • Serial properties: MacInDriverRefNum As Integer (r), MacOutDriverRefNum As Integer (r), Win32DriverHandle As Integer (r) • Sound: class SoundFormat Properties: Rate As Double (r/w), SampleSize As Integer (r/w), ChannelCount As Integer (r/w), Compression As String (r/w), SamplesPerPacket As Integer (r), BytesPerSample As Integer (r), BytesPerFrame As Integer (r), BytesPerPacket As Integer (r), Methods:, SoundFormat(rate As Double, SampleSize As Integer, ChannelCount As Integer, compression As String) [constructor], SelectSettings As Boolean • Sound: methods PlayLooping, Stop This release contains the following improvements to previous features: • (Mac) IDE: when a line of code is too complex to compile for 68k, the compiler says so rather than showing an assertion failure. • (Win32) Events: AppActivate, AppDeactivate, AppNewDocument, and MDI child window activates and deactivates. Note: event problems still exist. This release contains the following optimizations: • Built applications: applications built with 2.1 are faster than previous versions. Expect a Real World performance increase of 4%, although we have seen speed ups in the 30% range. Test your applications and let us know your mileage. • Edit field: REALbasic multi-line edit controls are up to 1% faster in benchmarks that stress this control. • Listbox: AddRow and RemoveRow now perform up to 10X faster. Various bug fixes caused these workarounds to fail: • (Win32) Printing: compensating for the printing bug by altering the location of the Drawstring y parameter will no longer work properly. • Sprites: Sprite code which worked around or took advantage of previous buggy behavior will need to be updated. This release contains the following changes to behavior: • (All) Changed runtime errors to not mention REALbasic or REALbugs to avoid end user confusion. • (DBCS) Changes made to Input Palette behavior on Double Byte systems • (DBCS) Space no longer inserted before dropped double-byte text when using WASTE text engine on double-byte systems. • (ODBC) LONG VARCHAR/LONG VARBINARY handling improved for ODBC driver • (Win32) Bevel button fixed to use Windows colors properly • (Win32) Built applications now have a VirtualPC compatible creator code and file type • (Win32) byRef: Calling floating point values by reference in Win32 still doesn't work, but now displays a more useful error message, and aborts the build. • (Win32) Drag and drop: pictures implemented • (Win32) Listbox: fixed to use Windows colors properly • (Win32) Listbox: Hierarchical lists now have a more standard looking disclosure widget. • (Win32) Listbox: now implemented checkbox column type • (Win32) Sound: Runtime explicitly shuts down DirectSound object to fix NT4 bug • (Win32) Text Styles: Error messages are displayed when trying to use unsupported text styles under windows. • (Win32) Windows: Floating windows implemented • About box: now reflects more accurate version information. • About box: updated to reflect new team members • Binding: Binding window now wider. This should allow you to see the binds better. • Build Dialog: Cancel button removed from Build Progress dialog box (it was redundant anyway) • Build Dialog: New and improved error messages are displayed when the a REALbasic build fails. • Build Dialog: the "Version Info" label has been changed to the more accurate "Package Info". • Confirmation dialog: removed dialog that appears whenever a user attempts to remove a method/property/new event/menuhandler/etc from a window/module/class. • Database: 4D database driver extended to support 4D Picture field • Database: 4D database driver now returns list of indexes (r) • Database: dtF database driver now returns better error messages • Database: dtF/SQL database driver improvements • Database: dtF/SQL database driver now returns list of indexes (r) • Database: error code for "primary key violation" changed from 2003 to 2005. • Edit constant dialog boxes now supports Cut/Copy/Paste for editfields • Find dialog: now automatically selects all of the Find string when brought to the front • IDE: Added a Scroll bar to the list box in the Constants dialog • Japanese OS: Support having US and Japanese IDE serial # installed on the same machine • ListBox: Slight change to semantics of Listbox.CellAlignmentOffset - now overrides ColumnAlignmentOffset when <> 0, would previously only override when a non-zero CellAlignment was set. • MacWindowPtr property now exported properly • Menus: New and or different icons have been added to the menus. • Online Reference content has been updated • Online Reference now has an introduction section and some spurious lines were removed. • Online Reference now renders read-only properties in bold • Saved project files now remember the position of the project window and code editor windows • Sound: Maximum number of simultaneous sounds has been increased from 4 to 16. • Strings: Attempts to create an overly large string from a buffer (e.g., with REALBuildString) now return an empty string, instead of causing the app to quit. • Tab panels: The format in which tabpanels are stored has been changed, projects with tabpanels that have been saved with this version will not display tabpanels correctly in older versions. • Text Encoding Vector: Workaround added for bug in Apple's Text Encoding Converter with invalid inputs • Threads: ThreadID property added to Thread class (for MacOS & Win32) The following bugs were fixed in this release: • (68k) Arrays: Boolean arrays now work. • (68k) Bevel buttons and placards are no longer depressed in 68k apps. • (68k) Bevel buttons no longer get "stuck" in 68k apps. • (68k) Declare Sub boolean return parameters fixed • (68k) Declare Sub parameter passing for boolean parameters on 68k fixed • (68k) Declare Sub routines now handle return values properly (including short) • (68k) Edit field: ReadOnly property fixed • (68k) Fixed bug with 68k declare functions (allocating return space) • (68k) IDE: Enabled property of various controls in 68k IDE fixed • (68k) Listbox: applications no longer crash when editable list box is clicked. • (68k) Listbox: applications no longer crash with LOADSEG failure if they didn't have a listbox • (68k) Plugins: Boolean parameters for Plugin functions are now treated as being 4 bytes long.

Let us know if the change is inadequate. • (DBCS) Input Manager behavior altered. Should appear on double-byte localised versions of MacOS more frequently • (DBCS) Uppercase, Lowercase, and InStr now work more reliably for two-byte character systems (e.g., Japanese). • (Mac) Drag item: no longer crashes with bad drag data, it just ignores it. • (Mac) Edit field: Control now updates immediately if user changes from no password to password mode • (Mac) Input Manager: The floating palette now works in both the IDE and in built apps. • (Mac) Japanese: LTrim, RTrim, and Trim no longer cut certain characters (e.g., "ha"). • (Mac) Menu bars: Using balloon help in menu bars no longer leaks memory. • (Mac) Static Text: fixed the odd refresh problem some were experiencing when using static text on a canvas control. Thanks Dr. Gerard Hammond, James Sentman, David Grogono, and Cortis Clark. • (Mac) Strings: Trying to read a very large file into a string returns an empty string instead of an out of memory error. • (Mac) Windows: Global floating windows now accept drags. • (ODBC) driver now supports out-of-order retrieval of column values (This was a limitation in ODBC which the driver now works around) • (PPC) Short Declare Sub short return parameters for PowerPC fixed • (Win32) Bevel buttons: fixed for disabled appearance • (Win32) Bevel buttons: value returns the correct value in code. • (Win32) Bevel buttons: value returns the correct value in code. • (Win32) Color: Mac <--> Win32 color conversions are more accurate. • (Win32) Cursors: Windows custom cursors now have the correct hot-spot • (Win32) Date: class properties update correctly • (Win32) Date: class updates without showing debugging dialog; this bug was introduced in a20 • (Win32) Declare Statement: Works specifically fixes problem with ptr (or memoryblock) within declares. • (Win32) Disclosure triangles value returns the correct value in code. • (Win32) DrawString: Fixed DrawString with an OpenPrinterDialog so that the coordinates specified in DrawString refer to the baseline and not the upper left corner • (Win32) Edit field: Default text in Multi-line edit controls now convert line endings properly for Win32 replacing carraige returns with carraige return line feeds. Note • (Win32) Edit field: now honors colors in EditFields. There are some circumstances where the editfield will not refresh properly however. Styled edit fields do not honor text color. • (Win32) Edit field: now supports changing fonts in EditFields. • (Win32) Edit field: password Editfields now work • (Win32) Edit field: Single line now refresh correctly on winNT. • (Win32) FolderItem: OpenAsPicture no longer leaks memory. • (Win32) FolderItem: OpenAsPicture will now open file types other than .bmp namely .gif, .jpg, .pic, .png etc. Note: QuickTime must be installed to open these additional types. • (Win32) Icons: built application icons have much more accurate color, blues and reds are no longer reversed. • (Win32) Icons: built application icons no longer constrain the icon to a diamond when the ICN# resource isn't present. • (Win32) Keyboard: now supports keyboard objects. The key codes are mapped directly from the Mac "Extended Keyboard Layout". The following is a list of keys which have mappings which aren't necessarily obvious: Option = Alt, Command = Windows, Help = Insert, Clear = Num Lock, F13 = Print Screen, F14 = Scroll Lock, F15 = Pause. • (Win32) Line controls update correctly • (Win32) Listbox: Hierarchical listboxes now highlight only the word portion of the each column this behavior is inline with how Windows handles this same issue, see Windows Explorer. • (Win32) Listbox: Inline editable listbox fixed • (Win32) Listbox: Pictures used in listboxes now appear in Color, the color white is transparent so when the row is highlit you don't see an ugly border around the picture. • (Win32) Listbox: reduced flicker in listbox redrawing. • (Win32) Listbox: Windows apps no longer crash when you attempt to sort an empty list box (i.e. - clicking in heading) • (Win32) MDI: MouseMove, MouseEnter, and MouseExit events now fire in MDI applications. • (Win32) Number: Format now handles exponents • (Win32) ODBC: SelectODBCDatabase fixed • (Win32) Picture: Graphics.FrameRoundRect and Graphics.FrameOval now uses Graphics.PenWidth instead of 1 • (Win32) Placards now update when their value is set in code. • (Win32) PopUpArrows facings can be set in code. • (Win32) Printing: Bug with Win32 printing to page >1 fixed • (Win32) Printing: Styled text printer now works. • (Win32) Quicktime: movie controller now is functional. • (Win32) Quicktime: no longer cause other interface elements to disappear or not refresh themselves. • (Win32) Quicktime: no longer crash on exit. • (Win32) StaticText: controls no longer cause a crash in win32 compiles when overlapping certain controls. • (Win32) StaticText: now honors the window background color • (Win32) StaticText: now redraw correctly when on top of other controls • (Win32) string alignment in offscreen buffer fixed • (Win32) Strings: CDbl, CStr and Format now use correct separators on foreign language systems • (Win32) Tab panels: no longer require a user refresh before looking their best. • (Win32) Tabpanels: bug with controls on Tab panels fixed • (Win32) Windows: Made Window Frames much more consistent, changes especially evident in MDI environment. Modals: now really modal and can be made re-sizable (GrowIcon) Moveable Modals: now can have close boxes (CloseBox), can be made re-sizable (GrowIcon), and now can have minimize and maximize boxes (ZoomIcon) Global Floating Windows: now float over every other window (except other Global Floaters) and have thin title bars Floating Windows: now float over every window in the application, but not over other windows in other applications. ShadowBoxes: now look distinct from PlainBox. Note: Minimize and maximize boxes require a close box to be present. This is done automatically if you specify (ZoomIcon) Note: Floating Window types can't have Minimize and Maximize Icons. Note: PlainBox and ShadowBox are modal on Win32. Note: MDI document windows must be closable, resizeable, minimizeable, and maximizeable. Note: Since there is nothing remotely similar to a rounded window in Win32 it behaves identically to a Document Window. • (Win32) Windows: apps now honor window background colors. • (Win32) Windows: bug with modal dialogs still behaving modal when hidden fixed • (Win32) Windows: Movable Modal and Floating Dialog windows no longer cause crashes on Win32 • (Win32) Windows: Window.show now forces window to be front most • About Box: layout has been slightly altered to better accomodate the Japanese version. • AppleEvent.EnumeratedParam exported properly • Arrays: Boolean array remove bug fixed • Arrays: Boolean arrays are now properly displayed in the debugger. • Arrays: Local arrays can now again be viewed in the debugger. • Binding: object binding now works in compiled apps. • Build Dialog: A crash in the build dialog (or with use of RGBSurface) on 8.0/8.1 machines has been fixed. • Build Dialog: has a more consistent appearance using themes. • Build Dialog: is properly closed when build fails • Build Dialog: now clears short version, long version, version info, and icon data when a new project is created. • Build Dialog: Quitting REALbasic after changing settings in the Build dialog now ask user if they want to save. • Build Dialog: The language popup now remembers last setting between builds. • Class: Setting class name equal to the superclass no longer causes a crash. • Code Editor: Built-in constants now autocomplete, just like other REALbasic keywords. • Code Editor: Home and End now work properly in the IDE source editor, and no longer move the insertion point. • Code Printing: Project Items such as Menus that would previously print a blank page when attempting to print now print their name. • Color Arrays: using Insert/Append on color arrays fixed • Constants: Fixed several bugs relating to constants and languages. • Controls: Many controls are now robust to calling 'close' in an event handler, then failing to return 'true' . • Controls: Reduced likelihood of crash when a bevel button or plug-in control is deleted during its own event handler. • Cursors: Corrected leak resulting from use of mouse cursors. • Cursors: If the cursor was hidden when a program aborted, it no longer is re-hidden when you restart the program. • Database: a REALbasic database could be opened multiple times concurrently • Database: Column name error for REALbasic database FieldSchema = said "AllowNull" when was really "NotNull" • Database: Crash when calling database.FieldSchema as first call on project database fixed • Database: Crashing bug in RDBD with accessing LONG VARCHAR fields fixed • Database: DatabaseCursorField.DoubleValue exported properly • Database: Fixed SQL 'OR' Operator in REAL DB. • Database: Fixes to Database.InsertRecord for external SQL databases for non-string values • Database: Many dtF database driver bugs fixed • Database: Memory leak fixed in SQLSelect • Database: PostgreSQL driver FieldSchema fixed • Database: PostgreSQL driver now recognizes CHAR fields • Database: PostgreSQL memory leak fixed • Database: REALbasic database aggregates fixed • Database: REALbasic database bug with updating incorrect column fixed • Database: REALbasic database bug with updating multiple columns fixed • Database: REALbasic database errors that weren't cleared fixed • Database: REALbasic database memory leak when opening/closing database fixed • Database: REALbasic database no longer crashes when you attempt to store a varchar data longer than the maximum data length (currently 8174 bytes). • Database: REALbasic database now properly returns an error on NotNull violations instead of silently failing • Database: REALbasic database now properly returns an error when inserting a record with an invalid column • Database: REALbasic database ORDER BY sometimes using incorrect sort direction for 2nd or later order columns fixed • Date: Dates now update automagically; no need for "d.totalseconds = d.totalseconds" work-around. • Date: ParseDate fixed • Debugger: Arrays should now always be viewable. • Debugger: editing key value during a breakpoint in a KeyDown event no longer causes a crash. • Debugger: no longer allows you to tab into uneditable fields (such as Doubles) and thereby to cause a crash. • Debugger: no longer crashes when killing the debug session if the user has the insertion point in an edit field in the variables window. • Edit field: Setting the password mode in an EditField no longer looses the current selection. (Mac and Win32) • Edit field: Single-line edit controls no longer receive duplicate KeyDown events. • Events: Using "quit" method now causes Close events to fire, just like Quit menu command. • Files: Fixed bug with IDE file tracking when project moved • Folder Item: FolderItem.Launch extended to support APPC, appe, and cdev • Folder Item: SelectFolder: now returns nil if the user selected 'Cancel' . • FolderItem: GetFolderItem now returns nil when given an invalid path.

Warning: this allows you to write to arbitrary memory and if used incorrectly, may crash the computer. • Memory: Compiled apps no longer hijack system memory, sound channels are now allocated only when needed (reduces system memory usage). • Memory: Out-of-memory conditions now display an error message and quit the application, rather than crashing the computer. • Numbers: Format() no longer produces a leading comma before three-digit numbers. • Numbers: Very large numbers no longer crash Format(). • Picture: Nil pictures passed to ExportPicture now raise a NilObjectException, rather than crashing . • Picture: Picture Mask memory leak fixed • Picture: Picture mask property exported properly • Picture: Picture.RGBSurface now returns nil for 8-bit pictures, and now works correctly for 16-bit pictures. • Plugins: Boolean parameters to plug-ins now work, even when a 68k plugin is called from PPC code. ...But please note: • Plugins: Bug fixed with plugin inclusion in built applications • Plugins: Plugin functions are now correctly linked in large projects • Popup menu: now raises OutOfBoundsException as required (instead of crashing) • project window: will no longer be opened offscreen. • QuickTime: Import Bug crashing with QT2.5 installed fixed (usually MacOS 8 machines) • QuickTime: Movie.looping and .palindrome can now be set at runtime with the desired effect. • QuickTime: QTEffectSequence class no longer returns empty pictures • Quit: Multiple close events are no longer fired when built apps quit. • Run: Code which previously invoked Debugger() now displays an error dialog instead. • Run: Crash which could occur when a breakpoint or error occurred while quitting a run in the IDE has been fixed. • Scrollbars: now proportional on systems which support that. • Sockets: no longer crash when the remote host disappears during a transaction. • Sockets: work in the IDE again (broken since a18) • Sound: IsPlaying property re-enabled • Sound: Looping sounds no longer leak channels (i.e., hold channels open after they have been stopped). • Sound: Looping sounds now have priority over non-looping sounds. • Sound: now stop when a run is terminated and you return to the IDE. • Sprite surface: An assertion failure while scrolling a SpriteSurface was fixed. • Sprite surface: insufficient memory now throws a nilObjectException rather than causing an internal assertion failure. • Sprite surface: is now more robust to errors such as insufficient memory. • Sprite surface: stopped with the Close method can now be restarted, even if it makes reference to surface.Graphics. • Sprite surface: stopped with the Close method can now be restarted. • Sprite surface: works in the IDE again (really, we mean it this time). • Sprites: now collide correctly even when straddling X=0 or Y=0. • Sprites: now collide correctly even when X or Y less than zero. • Sprites: now consistently use the world coordinate system. • Strings: InStr, InStrB: fixed a minor bug with return value of InStr(s, "") (and same for InStrB). • Strings: InStrB: now does byte-oriented, case-sensitive search (previously was equivalent to InStr). • Tab panels: can now use constants, as can multi-line edit fields and list boxes. • Threads: Issues with (stackOverflowExceptions) resolved. • Threads: yield more time to other processes & threads • Timers: which close their own window no longer cause occasional crashes. • Windows: Failing to return true after Closing a window within its event handler no longer causes a crash. • Windows: Fixed a crash which could occur when closing windows under certain circumstances. • Windows: Show/Hide methods now update visible property • Windows: Show/Hide methods now update visible property in compiled apps • Windows: Window and menu names are now validated just like class names. Various bug fixes caused these workarounds to fail: • (Win32) Printing: compensating for the printing bug by altering the location of the Drawstring y parameter will no longer work properly. • Sprites: Sprite code which worked around or took advantage of previous buggy behavior will need to be updated. The following known issues still exist in this release • (Mac) Conflict between Palm Desktop extension and menu items added to Help, on some versions of the Mac OS. Fix: rename extension to make it load last. • (Plugin API) Plugins should be recompiled with latest SDK to ensure that 68k code can be correctly called from PPC apps. • (Win32) byRef: Calling floating point values by reference in Win32 still doesn't work, but now displays a more useful error message, and aborts the build. • (Win32) Date: global function ParseDate(text As String, ByRef parsedDate As Date) As Boolean crashes. • (Win32) DisclosureTriangles and PopUpArrows do not refresh correctly unless self.refresh is used. • (Win32) Drag and drop: pictures implemented but still has problems • (Win32) Edit field: Single line colors do not work - styled multiline can be used instead. • (Win32) Edit field: Styled edit fields do not honor text color. • (Win32) Sound: Runtime explicitly shuts down DirectSound object to fix NT4 bug • DatabaseCursorField property: JPEGValue As Picture (r/w) doesn't work. • DatabaseCursorField property: MacPictValue As Picture (r/w), IntegerValue As Integer (r/w) doesn't work. • DatabaseRecord: properties MacPict As Picture (r/w) doesn't work. • DatabaseRecord: property JPEGColumn(name As String) As Picture doesn't work. • Debugger: Variables of type "Double" cannot be edited in the debugger. • Listbox: Deleting a row in a listbox if no row is selected and the scrollbar is at the bottom can cause list to appear incorrectly. listbox1.refresh or setting the listindex solves problems.
