Register dll fails when tlb file not generated.

[Vijay Chegu]

Hi,

I have a 32bit ATL COM dll which is generated without the tlb(/notlb option set in

midl). When i register the dll i get following error : 0x80029C4AL

Winerror.h says
//
// MessageId: TYPE_E_CANTLOADLIBRARY
//
// MessageText:
//
// Error loading type library/DLL.
//
#define TYPE_E_CANTLOADLIBRARY _HRESULT_TYPEDEF_(0x80029C4AL)


But if i generate the same dll with tlb my application works fine. That is i am

able to register the dll.

My build & Target machine is as follows:

1)Windows 2000 Professional
2)VC++ .NET 2003 (v7.1)
3)Platform SDK April 2003


Any help will be greatly appreciated.

Thanx and regards,
Vijay Chegu

You have to tell the ATL Framework not to register the Typelib.
You can do this by explicitly setting the parameter bRegTypeLib
to FALSE in the DllRegisterServer and DllUnregisterServer
entry points.

I.e.
STDAPI DllRegisterServer(void)
{
return _AtlModule.DllRegisterServer( FALSE);
}

Somewhere in the generated registration code it is set up to
register a type library in the resources. Don't know where it
is with attributes, but without attributes in VC 6.0 it was the
call to _Module.RegisterServer - the argument is set to TRUE
and you need to change it to FALSE. Same for UnregisterServer.
