FIX: Visual C++ Debugger May Not Break on WM_KILLFOCUS Message

 * }

Q102165

1.00 WINDOWS kbtool kbfixlist kbbuglist kbfasttip -- The information in this article applies to: - The Microsoft Visual Workbench, included with: - Microsoft Visual C++ for Windows, version 1.0 -- SYMPTOMS ======== If you set a breakpoint in the Visual C++ debugger on a line of code that is executed in response to a WM_KILLFOCUS, execution may not halt at that location when the application closes. STATUS ====== Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was corrected in Visual C++ version 1.5. This problem does not occur in Visual Workbench includes with Visual C++, 32-bit Edition, version 1.0. MORE INFORMATION ================ Microsoft Windows sends an window a WM_KILLFOCUS message immediately before the window loses the input focus. The Visual Workbench debugger properly halts execution on the code after the WM_KILLFOCUS message except when the user closes the application. This behavior occurs without regard to the specified debugging mode, either "hard" or "soft." This problem does not affect CodeView version 4.1 for Windows included with Visual C++ for Windows.
