README.TXT File README file for Microsoft(R) Visual C++ Version 1.5 Visual Workbench Debugger Patch #1 (C) Copyright Microsoft Corporation, 1994 This patch corrects problems with the Microsoft (R) Visual C++ (TM) Visual Workbench integrated debugger. INSTRUCTIONS FOR APPLYING THE PATCH: ====================================== - Make sure that the Visual Workbench is not running. - From an MS-DOS prompt, change to your Visual C++ 1.5 binary directory. For instance: C: CD \MSVC\BIN - Copy the patch files to the Visual C++ binary directory. The patch files are: PATCH.EXE PATCH.RTP - Make backup copies of the file that will be updated by the patch: MSVC.EXE - Run the patch program, by typing: PATCH The patch program indicates its actions as it runs. See the section in this file entitled "If you have trouble:" if warnings appear during this step. When the patch has been successfully completed, you may delete the patch files. BUGS FIXED BY THIS PATCH: =========================== - One of the debugger DLLs (TLW0NCL.DLL) was being loaded in the low 1MB address range and fixed there. This was using a valuable system resource unnecessarily - The IDE was not correctly handling calls to OutputDebugString() with very long strings specified or several such calls with no newlines. This was causing the system to become unstable when during debugging applications that were using OutputDebugString() in this way. If you have trouble: ==================== If you have problems running this patch: - Make sure you copied the appropriate patch files. - Make sure you have the correct version of the files to be updated. This patch will only patch files from Visual C++ v1.50 for Windows. If, after checking these possibilities, you still have problems and you wish to contact us, please refer to the Obtaining Technical Support selection on the Help menu of the Visual Workbench, or open up the file PSSWH.HLP in the Windows Help utility. PSSWH.HLP is located in the helpfiles directory for Visual C++, by default C:\MSVC\HELP.
