SYMPTOMS

When you build an .ocx, Regsvr32.exe is always called whether or not the compilation succeeds. If you start the build by pressing F5 (Build:Debug :Go), and there are compiler errors, after Regsvr32.exe is run, the debugger will be launched if you have an existing copy of your debug executable. This same problem occurs on any project that uses a custom build option for the project. Note that having custom build settings for individual files in the project will not effect this behavior.

RESOLUTION

Remove the custom build command, and add a custom tool to the Tools menu. In the case of the .ocx file, Regsvr32 is already registered as a Tool. You can run Regsvr32 as a separate step when necessary.

STATUS

Microsoft has confirmed this to be a bug in the Microsoft products listed at the beginning of this article. This bug was corrected in Visual C++ version 5.0.

MORE INFORMATION

Steps to Reproduce Problem

Create a default .ocx project by selecting OLE ControlWizard as the project type.
Successfully build the .ocx file.
Introduce a compiler error into your source code.
Press F5 to build your application. After the failed build, Regsvr32 is launched followed by the debugger.
