importing a tlb in Visual Studio 2005

[kurt.kurtsmith]

I am trying to import a tlb from a COM server(exe) I wrote with the
following statement:

#import "C:\\em2\\EM\\src\\core\\UMOSEFax\\Debug\\UMOSEFax .tlb"
no_namespace auto_search

the tlh and tli are generated in the debug directory but I get the
following error:

Error 1 error LNK2019: unresolved external symbol "long __cdecl
_com_dispatch_method(struct IDispatch *,long,unsigned short,unsigned
short,void *,wchar_t const *,...)" (?
_com_dispatch_method@@YAJPAUIDispatch@@JGGPAXPB_WZ Z) referenced in
function "public: short __thiscall IUMOSEFax::AddFile(class
_bstr_t)" (?AddFile@IUMOSEFax@@QAEFV_bstr_t@@@Z) command.obj

Is there some linker setting I am missing here? The DLL I am trying
to compile is unmanaged.

It looks like you're missing comsupp.lib from your linker inputs, or
possibly your library path is incorrect so the linker is finding an
incorrect version. I believe that the compiler-generated files
automatically reference the correct library (there are actually 4 different
libraries), so I'd lean towards the lib path being off. Try adding /verbose
to your linker settings to see where (or if!) the linker is finding
comsupp[w][d].lib.

-cd

Here is the verbose output. I am assuming it is finding the right
comsupp.lib as it finds the 8.0 version?

I am a moron. I just realized I was not linking against the wide
version.

Sorry for wasting your time.

Not a problem - we've all been there :)
