---------------
Online Licenses
---------------
Borland now provides the software license online. Refer to
the file license.txt in the root directory of the CD for details.
--------------------------
Redistributable Files List
--------------------------
Refer to the file redist.txt for a list of redistributable
files for Borland C++ 5.02.
----------------
New IDE Features
----------------
The IDE includes many usability enhancements in this release.
They are listed briefly in the following sections. Refer to
online Help for details.
Compiler Enhancements
---------------------
* New 32-bit compiler (BCC32.EXE) provided with this release
* A Make following a failed Build All rebuilds from the point
of failure
* New compiler option under Options|Project|C++ Options|
General called Zero-Length Empty Class Member Function (like -Vx)
Editor Enhancements
-------------------
* Read-only files identified by an "R" after the file name
* Modified files include an asterisk (*) after the file name
* Search|Replace includes a Change All option
* IDE remembers the cursor position of the last 100
edit buffers that you closed
* IDE automatically loads the Tips script to display tool tips
* Cursor changes in left gutter to indicate that a click
will drop a debugger breakpoint
Debugging Enhancements
----------------------
* New options in Options|Environment|Debugger|Debugger Behavior:
Do not save files or prompt when debugging and Do not prompt
when attempting to run 16 bit applications
* New option in Options|Project|Compiler|Debugging:
Detach Debug Information from OBJs
* Debugger status glyphs: Lightning bolt (if running)
and Pause Process (if stepping or at breakpoint)
* Debug menu: View Locals command creates Local Inspector (to
watch local variables) when the IDE Debugger has a process loaded
* The Watch window shows values in hex, decimal, or both formats
* CPU View stack pane indicates the current position
* While debugging, editor tooltips display the value of the symbol
under the pointer
Message Window Enhancements
---------------------------
* An .RC file's source date and time format
reflect the format of the country setting
* The default position of the Message window has changed
* You can use Ctrl+ A to clear the Build tab
* Clear before Make/Build in Options|Environment|Preferences
* Double-click on an unresolved external error message
in the Build tab opens the file with the external reference
Project Management Enhancements
-------------------------------
* Project menu: Stop Background Task appears during an
asynchronous build
* Project window glyphs: A red check mark (node has
Local Overrides) and a clock with a red X on it
(node out of date and will be rebuilt on the next make)
* The default position of the Project window has changed
* Compatibility: Two new Project Options on the C++ Options|C++
Compatible dialog, Destructor Cleanup Compatibility and Class
Layout Compatibility
General Enhancements
--------------------
* Preprocessor: Invoking the preprocessor automatically loads
the output into the edit buffer
* Syntax highlighting: Scope delimiters ) and } can be
customized; preprocessor directives highlighted only
instead of highlighting the whole line
* File|Open dialog boxes: Enable filename completion
available in Options|Environment|Preferences for files
and directories
* Keyboard Shortcuts: You can use Ctrl+S to find the ~, <, and >
characters
* Windows NT: Shutting down the computer now saves an open
.IDE file.
------------------
Incremental Linker
------------------
Borland C++ provides an incremental linker that dramatically improves
link times (after the initial link). To use it, check Incremental
Linker on the Options|Project|Linker|32-bit Linker page.
----------------------------------------
Interoperability with Borland C++Builder
----------------------------------------
If you have Borland C++Builder, you can add the C++Builder .MAK
makefiles as nodes to your BCW projects. Refer to BCW.HLP for
more information.
----------------------
New Scripting Features
----------------------
* File maintenance/navigation script (DIRVIEW.SPP)
* New method ProjectStopBackgroundTask() to terminate
asynchronous build/make/compile/transfer
* remove_view_menu_item function in MENUHOOK.SPP lets you
remove IDE main menu items
* SearchAll hot key changed from A to L.
(A clears the Message tab.)
------------------------------
New Resource Workshop Features
------------------------------
* 32-bit custom control DLL support in
Options|Environment|Resource Editors|Control Libraries
* New menu command Dialog|Resize to Content
* Dialog editor enhancements
* Check for Duplicate ID on the Dialog menu
* Dynamic IDE status bar
* Entry of DBCS characters in the menu editor
* Code page support in Resource compiler through -c switch
and #pragma code_page(ID-num)
------
Issues
------
New 32-bit Compiler Rule
------------------------
The new 32-bit compiler implements a language requirement that may
break some existing code. The new rule is that you cannot pass a
temporary variable by reference--you must pass it by const reference.
For example, given a function with this prototype:
func1 (TMyClass& o);
the following call used to be acceptable:
func1 ( TMyClass() );
However, you must now change the call to:
func1(TMyClass const & 0)
Some of the OWL examples have not been updated for this new change.
Command-Line Options
--------------------
The command line compiler creates multithreaded applications
by default. The -WM option is on by default.
If using the -i and -s command-line options together, note that the -i
must precede the -s to work properly.
Compiler/Linker Errors
----------------------
If you receive the following compiler and linker error messages
when you compile from the command line:
Error: Unresolved external 'TApplication::Dispatch(TEventHandler::TEventInfo&,int,long)'
referenced from module GDIDEMO.CPP
Error: Unresolved external 'TWindow::Dispatch(TEventHandler::TEventInfo&,int,long)'
referenced from module GDIDEMO.CPP
it most likely means you are compiling as a multithreaded application,
but are linking with the single-threaded OWL libs. This is because
multithread is now the default application type. To remedy this,
add -WM- to your options to turn multithreaded targeting off.
Restricted Keywords
-------------------
The following keywords are reserved for use in Borland C++Builder:
__automated
__classid
__closure
__dispid
__property
__published
Don't use these in your Borland C++ programs.
Multiple Declarations for HSZ
-----------------------------
If the error Multiple Declarations for HSZ is displayed, you need to
edit \BC5\INCLUDE\WN32\DDEML.H and include the following statement:
#define __DDEML_H
STL Stack
---------
Although unlikely, if you want to use a stack of vectors of bools,
you must define the following before any of the header files:
#define RWSTD_NO_BOOL
------------------------
OpenHelp 6.0 Upgrade Kit
------------------------
The OHELP60 directory on the CD contains files that let you upgrade
to OpenHelp 6.0. If you have C++Builder installed on the same computer
as Borland C++, you already have OpenHelp 6.0. In this case, the upgrade
merges the Borland C++ and C++Builder OPENHELP.INI files.
See OPENHELP.HLP for information on using OPENHELP 6.0.
Upgrading to OpenHelp 6.0
-------------------------
If you have only Borland C++ on your computer
---------------------------------------------
Run OHELPNEW.BAT. This batch file takes one parameter: The parameter
specifies the drive and directory in which BC5 is installed. Enter a
colon with the drive letter, followed by the backslash and directory
name, e.g. C:\BC5
Example: OHELPNEW C:\BC5
If you have Borland C++ and C++Builder on your computer
-------------------------------------------------------
Run OHELPRPL.BAT. This batch file takes two parameters: The first
parameter specifies the drive and directory in which BC5 is installed.
Enter a colon with the drive letter, followed by the backslash and
directory name, e.g. C:\BC5 The second parameter specifies the drive
where Borland programs are installed. Enter the drive letter followed
by a colon, e.g. D:
Example: OHELPRPL C:\BC5 D:
