SYMPTOMS
When building an OLE Control project in Visual C++ versions 4.0, 4.1, or 4.2 that was created in version 2.2, you may receive the following warning:

Failed to (or don't know how to) build 'D:\test\Ocx22\$(OUTDIR)\OCX22.tlb

where OCX22.tlb is the type library for the OLE Control.



CAUSE
This error occurs if the type library does not already exist or under the following circumstances:
 * The Visual C++ 2.2 project has not been built as a Visual C++ 2.2 project before it is converted to Visual C++ 4.0, 4.1, or 4.2 and then Built under Visual C++ 4.0, 4.1, or 4.2. -or-


 * The .tlb file is deleted and rebuilt. Note that deleting the .tlb file occurs when you delete the obj32 build directory.

In either of these cases, if you choose Rebuild All, the error does not appear; nor does it appear in subsequent builds unless the type library is deleted.



RESOLUTION
This warning can be safely ignored. The OLE Control should compile and run without problems.



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.
