Regsistering ATL (regsvr32) Problem: CAtlDllModuleT and DllRegisterServer (atlbase.h) in VS2003 versus VS2005


I make a new "ATL Project" and add an "ATL Simple Object"  to it using VS2003. I choose options so that it is an attributed object, never aggregates and supports dual interface and do not provide support for COM 1.0. This will generates a .dll  file.

When I use regsvr32.exe to register it, this tools returns without any error but it really does not write the AppID in the registry (the contents of the .rgs file does not seem to be processed).

But when I open this project in VS2005 and build it there without any modification (except that obviously solution is converted to V8.0), regsvr32 returns successfully again but the registry items are now added correctly under the AppID.

As you now the attributed dll objects  of ATL projects use default implementation for DllMain, DllRegisterServer, DllUnRegisterServer, DllCanUnloadNow, and DllGetClassObject using the "module" attribute in class implementation file (CAtlDllModuleT base class):

Any Ideas of what is the difference between these two cases. Or is there any known bug regarding ATL projects in VS2003. And how can we overcome this problem?

OK I could solved my problem :)

The problem was originating from expandable attributed code.
if you assign /FX to compiler switch of your attributed module, you see that DECLARE_REGISTRY_APPID_RESOURCEID is injected in VS2005 but not VS2003. I consider it kind of a BUG in VS2003.

Thanks for your help.

Can you try using depends.exe and see all the depended dll's are there in both the versions of exe/dll?

Al faAuthor Commented:
The problematic dll has dependency to "SHLWAPI.DLL" in addition to that of the working one.

 Obviously the problematic one depends on "MSVCR71D.DLL" (since built with VS2003) and the working one depends on "MSVCR80D.DLL" (since built with CS2005)

Many Thanks,
