DLL-Project - include stdafx.h

Hello,

I've tried to add a few headers and cpps to the dll-project. With this extension Visual Studio forces me to include the stdafx.h into the DLLMain.cpp. If I do this then I got errors because of the multiple definitions (p.e. DECLARATIONTYPE etc.). How can I solve this problem?

Hi Carsten,

If I remember right you only need to use stdafx.h if you have chose to use pre-compiled headers. Turn off pre-compiled headers and remove stdafx.h.

Hi Lars,

I've turned off already precompiled headers. VS includes a stdafx.h to add the MFC-components. I've tried to rename this header but without a result. I've got always an error from the linker " fatal error LNK1169: Found at least one multiply-defined symbol. " (translated - german version). The main problem seems to be the definition of DECLARATIONTY.

Hi,

Try to remove the stdafx.h from the code and the disk.

If you do not get it to work, can you send me the project?
I have Visual Studio 2008 std and Visual C++ 2010 Express.

Hi Lars,

I've tried to remove stdafx.h but it looks like that MFC is inextricably linked with stdafx.h. Maybe there's a way to change the definitions of DECLARATIONTYP?!

MFC needs a full-version of Visual Studio. Because of that I'm using VS 2010 Professional. I've try to send you the project. Thanks for your helping hand.

greetings

Carsten
