BUG: VC++ Project Settings Saved Only on Normal Exit

• Microsoft Visual C++, 32-bit Editions, versions 2.0, 2.1, 2.2, 4.0, 4.1, 4.2, 5.0, 6.0

SYMPTOMS

Visual C++ project settings can be lost if a project is terminated by any means other than a normal exit. Loss of settings can result despite clicking OK after making a change to a project setting.

RESOLUTION

To avoid losing project settings, close the project before leaving the machine for an extended time. Also, on the File menu, click Save All before performing a task that could crash the machine.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

Loss of project settings can occur on abnormal termination of the project, which could result from power loss or other reasons. This risk can be minimized by closing the workspace before leaving the machine for an extended time or by clicking Save All on the File menu before performing a task that may crash the machine.

Steps to Reproduce Behavior

1. Create a new Visual C++ Win32 Application project, give it a name, and click OK.
   
   NOTE: Depending on the version of Visual C++ in use, a wizard may supply additional dialog boxes. Provide appropriate responses to these dialog boxes.



2. On the Project menu, click Settings, and then click the C/C++ tab. In the Warning level combo box, select a different level than the default level and then click OK.



3. Terminate the project abnormally by pressing CTRL+ALT+DEL to bring up the Task Manager in Windows NT or the Close Window dialog box in Windows 95 or Windows 98. Highlight the Visual C++ task and then click End Task.
   
   NOTE: Do not respond to a dialog box asking if changes are to be saved. Instead, click End Task in the dialog box that follows.



4. Start Visual C++ again and open the Visual C++ project that was just terminated abnormally.



5. On the Project menu, click Settings and then click the C/C++ tab. The bug described in this article is demonstrated by the loss of the project setting change made earlier.



6. Verify the workaround by making another setting change, click Save All on the File menu prior to abnormally terminating the project as described in step 3, and then repeating steps 4 and 5.
