c++ - LNK2022 Error When Using /clr

Question

I'm having a problem linking a C++ project in VS2008 when using the /clr compile option. I am getting the following build errors:

Class1.obj : error LNK2022: metadata operation failed (8013118D) : Inconsistent layout information in duplicated types (_PROPSHEETPAGEA): (0x0200046f).
Class1.obj : error LNK2022: metadata operation failed (8013118D) : Inconsistent layout information in duplicated types (_PROPSHEETPAGEW): (0x02000473).

LINK : fatal error LNK1255: link failed because of metadata errors

I have no idea what PROPSHEETPAGEA and PROPSHEETPAGEW are referring to. I checked online to see Microsoft's description of the error but am at a loss as to what it means. http://support.microsoft.com/kb/324088

To resolve this problem, add unique identifiers when you use Managed Extensions for C++ so that you avoid using anonymous structures as global variables.

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article. This bug was corrected in Microsoft Visual C++ .NET (2003).

Any ideas would be greatly appreciated.

EDIT

After doing a ildasm on Class1.obj I extracted two messages:

I'm not sure what all this means, but it looks as if the second entry is identical to the first with the exception of the attributes being defined backwards.

Answer 1

I had this exact same problem today on one of my projects. I solved it by rearranging my header files. Problem was I had moved a header file to the top of the cpp file, before the file that was including windows.h. So, once I reverted the include order, and put windows.h back at the top of the cpp file, it fixed everything.

very wierd fix, but it worked for me.
