On occasion, it is possible for Visual C++ to get very slow. What may happen periodically is that some of the working files may become corrupted. Fortunately, this problem can be solved easily.

To solve this issue:

• Close Visual C++.
• Open a command line prompt in the directory that your source code is in.
• Clean out all the intermediate files with this line at the command line prompt.

> del /s /f *.obj *.opt *.ncb *.lib *.ilk *.pdb *.idb *.bsc *.pch *.sbr

This will completely clean out all the intermediate files from your project directory. You can then rebuild your project and the performance of Visual C++ will be back to normal.

	Exercise extreme caution and only run this command in the directory of your application.
