ZIF Editor Revision History 10-24-93 ■ Version 2.12a . Fixed problems with the Browse for Compressed File Directory screen being off-centered, and pressing Cancel unexpectedly terminating the program. Fixed potential problems on the Browse for Program screen. . Fixed problem introduced in version 2.12 where the Executable Filename was not being copied to the Compressed Filename field on the Compression Options Screen, and the Program Directory was not being copied to the Compressed File Directory field on the Compression Options screen. This could result in ZIP'R issuing an error message that the program directory did not exist. . Fixed potential problem where the open and delete file routines would not always change to the proper directory when the user entered a manual full path file name. Problem was due to recursion. 09-14-93 ■ Version 2.12 . Fixed minor problem where .IN was being appended to the end of the .OUT filename field when TAB or ENTER was pressed. . Added code to set the default value to 1 for the maximum concurrent users of a program if the field read from the .ZIF file is blank. . Added code to automatically append a colon and a backslash ":\" on the paths screen if there is only one character present in the field. . Altered size of Help screen to fit within the bounds of the new menu format. . Fixed tab order index on network options screen. . Fixed a problem where "*.IN" and "*.OUT" were not always being used as the default pattern on a delete operation. . Increased the STACK statement in the internal code to avoid "Out of stack space" error messages. . Rewrote routines to read the ZIPR.INI file and the individual .ZIF files. New routines are more bullet-proof against error. . Combined several screen to reduce the size of the code. . Added features to the open and delete file screens to make it automatically change to a different drive and directory when a user enters a manual path and/or filename. . Made drastic modifications to the appearance of the ZIF Editor. Created a solid background to replace the old, textured look. Changed all forms and corresponding code to respond properly to the new interface. . Fixed a potential problem where parameters were being written to the .ZIF file in UPPER CASE. 08-14-93 ■ Version 2.11 . Fixed a problem on the Compression Options screen where the options ZIP0, ZIP1, ZIP2, ZIP3, and ZIP4 were not being added to the Compression Type list box when Use Advanced Options was checked. 07-05-93 ■ Version 2.1 . Changed exit command on menu to "Exit ZIF Editor" instead of "Exit". . Removed the ability to use the ENTER key to access the Save button from the IN DOS Commands and OUT DOS Commands text boxes on the .IN and .OUT editing screens. This caused a problem since users might not be able to enter a multi-line .IN or .OUT file. . Added code to write "RegistrationName=" and "RegistrationNumber=" prefixes before the Registra- tion Name and Number in the ZIPR.INI file. Added code to make sure that the ZIF Editor can read both old and new formats of these two fields. . Removed unnecessary variable declarations to reduce code size. . Combined all three Delete File screens into one common screen to reduce code size. (Compressed size reduced by about 3K.) Updated code to reflect common screen. . Combined all three Open File screens into one common screen to reduce code size. (Compressed size reduced by about 3K.) Updated code to reflect common screen. . Added a control array to the Default Paths screen to reduce code size. . Hid the main menu from view when any other screen is available for editing. . Fixed problem where the Browse Program routine was calling the wrong path statement when checking for the validity of a filename. . Added code to allow the ENTER key to function as a TAB key in most fields, excluding file and directory list boxes. . Modified code to add a linefeed after each carriage return when writing a .IN or a .OUT file. 06-12-93 ■ Version 2.0 . Released as Version 2.0 with ZIP'R Version 4.0 06-12-93 ■ Version 1.8 (Internal BETA version. Not released.) . Added a Clear Screen command to the File Exit routine to erase the screen before returning to the operating system or a DOS prompt. . Fixed problem where using a text box as a multi- line label allowed the user to select and delete the internal text using the mouse, even though no tab- stop property was set to the item. Changed all text boxes to labels to prevent future problems. . Fixed Logo Screen problem where clicking on the logo screen would cause it to have a shadow, only to disappear once another form was selected. Shadow now appears all the time. . Added code to set ZIPR.INI file defaults if any entries are blank after reading the file. 06-04-93 ■ Version 1.7 (Internal BETA version. Not released.) . Created subroutines with common code to reduce code size and simplify. . Shortened form names to decrease code size and alleviate memory problems. . Added code to change the mouse cursor to a smiley face when forms are loading, or events are being processed. This indicates to the user that the ZIF Editor is in the process of performing a set of instructions. . Issued a call to read the ZIPR.INI file each time the settings are accessed from the main menu, instead of reading the file only when the form is loaded for the first time. . Added code to warn users before performing a delete file operation. . Changed the way the .HLP file is loaded. Since this file is pre-formatted, it can be loaded as a single string. (Much faster.) . Added error trapping when users attempt to type a full path in the open or delete filename field. . Added code to trim any potential spaces from the beginning or end of the Registration Name, Registration Number, Prelog Delay, and Epilog Delay fields. . Changed code to copy the program directory to the compressed file directory field each time the program directory loses the focus, as long as the "Use Alternate Directory..." checkbox is not checked. . Added check to make sure that help file exists before attempting to display in help screen. . Added help screen with general information about the ZIF Editor. . Added registration information screen with instruc- tions on how to register ZIP'R and the ZIF Editor. . Added code to automatically append a backslash to compression path entries if one is not present. . Added code to read and interpret AlternateDIR field from old style ZIF files. . Added error trapping when the ZIF Editor attempts to access a floppy drive that is not ready. If the ZIF Editor detects that the drive is not ready, it changes the drive back to the default. . Added code to trap the [ENTER] key when a file list box is selected. If a file is not highlighted, the [ENTER] key will highlight it. Once a file is highlighted, the [ENTER] key will open or delete the file. . Added code to trap the [ENTER] key when a directory list box is selected. When [ENTER] is pressed, the directory is changed, and the file list updated. 06-02-93 ■ Version 1.6 (Internal BETA version. Not released.) . Changed operation of pattern buttons on program browse screen. Once *.* is selected, any existing check marks are removed from the *.BAT, *.COM, and *.EXE check boxes. Likewise, once *.BAT, *.COM, or *.EXE is selected, any existing check mark is removed from the *.* check box. . Added code to make sure that when the Update Option check box is disabled, the check mark is removed from the box. . Added code to warn a user if changes have not been saved before exiting from the ZIF editing screen. . Assign "new" ZIF file variables only when "Save" or "Cancel" is selected from the main ZIF editing screen. This reduces code size, and slightly increases the speed of saving variables on the Compression Options screen. . Changed Update Option check box to be disabled (grayed) instead of invisible when non-PKZIP options are selected on the Compression Options screen. . Changed option boxes for *.BAT, *.COM, *.EXE, and and *.* on program browse screen to check boxes. This allows different combinations of file types to be listed at the same time, giving users the option to see only the files they choose. . Added code to make sure there are no files high- lighted when the program browse command button is selected. . Added code to open and delete screens to always display the current path with a filename or wildcards after it. . Moved code from open and delete load routines to main menu open and delete click routines to clean up unnecessary placement of variables. Deleted load routines for all open and delete screens. . Removed redundant code that selected text in the first field of a screen when a form was loaded. . Added code to make sure a file is entered in the filename field and exists on the program browse screen when "Ok" is selected. Otherwise, an error message will display. . Fixed problem where .ZIF, .IN, and .OUT extensions were being added to the filename field on the open and delete screens when the field already contained a filename with an extension other than .ZIF, .IN, or .OUT. . Fixed problem where .ZIF, .IN, and .OUT extensions were being added to a blank entry in the filename field when the open or delete filename field lost the focus. . Added code to the open and delete file routines to make sure a filename is entered and exists before attempting to open or delete it. . Fixed typing error that caused only the first four characters of the Executable File field to be high- lighted when the field was selected. . Added code to initialize .ZIF, .IN, and .OUT file variables when the open command is selected from the main menu. . Added additional variable defaults for compression options to the InitializeZIFFileVariables sub- routine to eliminate the possibility of some fields not being properly reset. . Added code to set the default program browse directory to the root of the program drive if the program directory field is blank or cannot be found. . Fixed problem where a double backslash (\\) would appear on the current path when attempting to open or delete a file from the root directory. . Removed redundant code that triggered a refresh of the file lists at other points within the code. . Added code to update (refresh) the open and delete file lists when "Open" or "Delete" is selected from the main menu. . Created common subroutines call "InitializeINFile- Variables" and "InitializeOUTFileVariables". Used these routines to clear any remaining data once the "New" command is selected from the main menu. . Added code to make sure the "Use Alternate Direc- tory for Compressed File" check box was checked when opening a file, if the Compressed File Directory was different from the Program Directory. . Added code to return the focus to the ZIF Editor's main menu after selecting "Save" or "Cancel" from the IN and OUT editing screens. . Added code to instruct the alternate compressed file directory browse screen to display the directory specified in the Compressed File Directory field. If one does not exist, it will display the directory in the Program Directory field. If this does not exist, it will default to the current drive and directory. . Added code to instruct the program browse screen to check if a program path existed before displaying the screen. If a program path exists, the program browse screen changes to the correct directory before showing the file list. If a program path does not exist, the program browse screen defaults to the current drive and directory. . Removed unnecessary code of saving variables that were passed to the old style ZIF files. Since the new ZIF Editor only writes new style files, the old code was no longer needed. 05-30-93 ■ Version 1.5 (Internal BETA version. Not released.) . Changed the default file list pattern for the program browse screen to *.*. . Changed explanation for .IN and .OUT commands on the editing screens for IN and OUT files. . Added code to set ProgramConcurrentAccess to 1 when reading a .ZIF file if the initial entry is blank. . Removed code to write old style ZIF files, since the ZIF Editor automatically converts old style ZIF files to new style ZIF files. . Added common subroutine called ZipNameLostFocus to add a compressed file extension to the Compressed Filename field when an old style ZIF file is loaded. . Removed default designation from all "Save" and "Ok" command buttons. . Added code to reset the current path and filename on an open or delete screen after opening or deleting a file. . Added code to reset filename field on open and delete screens to *.ZIF, *.IN, or *.OUT after opening or deleting a file. . Added code to set focus to main menu after selecting Cancel on an open or delete screen. . On warning message about overwriting a file, added code to return the cursor to the filename field if "Cancel" is selected from the dialog box. . Added code to check if a .ZIF, .IN, or .OUT file exists before attempting to save it. If the file exists, a warning message is issued, asking whether or not the file should be overwritten. . Added code to reread open and delete file lists after saving a new .ZIF, .IN, or .OUT file. . Added code to reread open file lists when OK or Cancel command buttons are selected. . Widened Network Options screen to completely cover the logo screen. . Changed all "ENTER = Ok", "ENTER = Save", and "ESC = Cancel" to "Ok", "Save", and "Cancel".

Added code to make sure that a backslash is located at the start of the Program Path and Compressed File Directory fields, even if another backslash exists at a different location in the field. . Added common subroutine called CFDLostFocus to trim and format information located in the Compressed File Directory field. . Passed the current path of the compressed file directory browsing screen to the Compressed File Directory text box. . Disabled access to the Compressed File Directory and the associated browse button when the "Use Alternate Directory for Compressed File" checkbox is not selected. This "grays" the controls, preventing mouse and keyboard users from accessing them. . Added code to trim potential drive specifications from the Program Directory field. . Created common subroutines for LogDirectoryLostFocus and ProgramNameLostFocus. Added calls for these routines when the OK button is selected from the program browse screen. (This trims the Executable File field, copies it to the Compressed Filename field, and copies the Program Directory field to the Compressed File Directory field. . Added code to instruct a double-click on the program browse file list to trigger the OK command button. .

Added intermediate variable before calling the subroutine SetOldZipTypeListIndex to fix a problem where the Compression Type was not being read and interpretted from an opened file properly. . Fixed a problem where the filename of a new style ZIF file was not being properly transferred from the opening screen to the ZIF editing screen once the file had been opened. . Fixed a problem on the Open File screen for .ZIF, .IN, and .OUT files, where typing a name in the Filename field and pressing [ENTER] would cause an error stating "The file you selected does not exist." . Fixed a problem on the Open .ZIF File screen that caused the Current Path to be incorrectly updated to the default program path when OK was selected. . Updated the network options screen to explain the purpose of the Maximum Users field. . Moved cursor to text editor field on IN and OUT editing screens after opening a .IN or .OUT file. .
