  1. POProblem creating COM-library only containing enum's
    text
    copied!<p>I'm am doing a COM-interop project. Substituting some VB and C++ ATL COM projects with C# and .NET Interop. When i define enumerations in .NET and they are made ComVisible, they get exposed as Typelib.EnumType_EnumValue enstead of just Typelib.EnumValue. The typelib exporter does this to ensure that the value names are unique. But i know that all my enum's are unique, so i don't want the underscores. Also there is a lot of client code that needs alteration if i don't get rid of the underscores.</p> <p>To find a solution to this problem, i have defined the enum's in an IDL-file and creating a typelib and .Net interop from this. </p> <pre><code>[ uuid(64893FD4-359D-46B9-BC1E-48C055796104), version(1.0), helpstring("ABC"), helpfile("AAA.chm"), helpcontext(0x00000001) ] library EnumTypeLib { importlib("stdole2.tlb"); typedef [uuid(8FF85069-C4E2-4540-A277-4C0F3C19B807), helpstring("MyEnum"), helpcontext(0x00000066)] enum MyEnum { Value1 = 0, Value2 = 1, } MyEnum; }; </code></pre> <p>I create a typelibrary with MIDL.exe which produces a tlb-file. </p> <p>And i create an assembly with the tlbimp.exe. signing the assembly with the same key as the other Interop assemblies.</p> <p>tlbimp OpenStructureAdapterEnum.tlb /keyfile:KeyFile.snk </p> <p>Then i register the assembly with regasm.exe This assembly looks fine and contains the enum without underscores. But the problem is that a can't see the COM-library from OLE/COM Object Viewer or from VBA or VB6. And when i reference the enum from another COM-exposed assembly, the part of the interface containing references to the enum, gets exposed as resticted methods.</p> <pre><code>[restricted] void Missing7(); [restricted] void Missing8(); [restricted] void Missing9(); [restricted] void Missing10(); </code></pre> <p>How can i create a COM library containing only enums (without underscores) and referencing these from other .net Interop assemblies?</p>
