MFC DLL
-
Dear All, I have created a MFC DLL in VS 2005. I have included this dll (dll and lib) in the VS 2003. The project compiled and running well. But, when I run the exe in another system (XP with SP3) without VS then the exe throws an error saying that "Application not correctly initialized". I dont know the reason of this problem. Please help me... Regards, Bhanu
You will need to download and install the vc redistributable package on the target computer. You can download it from here[^]. If you have the vc2005 service pack 1 installed, you should download the version for service pack 1 (see the links at the bottom of the page). When executing this on the target machine, it will install the C-runtime libraries and MFC libraries. Another option would be to statically link to the C-runtime library and MFC libraries.

Charting control [v1.5] OpenGL game tutorial in C++Dear Moonen, Thank you so much for your reply. Installing vcredist_x86.exe solves the problem, but I want my dll to be self sufficient irrespective of the versions. I created a MFC DLL as "Regular DLL with MFC statically linked". The dll is created properly, but if I include in my MFC dialog based project I got linker error (error LNK2019: unresolved external symbol). Please help me... Many thanks in advance. Bhanu

What is the exact error message ? Your MFC application also needs to statically link to the MFC.

Can you please tell me how to modify the settings of my MFC application which access the DLL. Many thanks. Bhanu

Well, looking at the error message it seems something else. From where is this _GetDevice function coming from ? If it is defined in a library, did you add the library to your project ?

Yes the method is defined in the library. I included the library and .h file in to the application. But interestingly if I create the MFC DLL as "Regular DLL using shared MFC DLL" and include in the project then this linker error is not coming. The above error is getting when I create the MFC DLL as "Regular DLL with MFC statically linked". Please advice. Many thanks in advance. Bhanu

It's a bit strange... Anyway, you can try to link your project statically to the MFC's but I'm not sure it will solve the problem. For VC2005, open the project properties, go to general, and for "Use of MFC" select "Use MFC in a Static Library".

Charting control [v1.5] OpenGL game tutorial in C++I am sorry. Already my project setting is using "Use MFC in Static Library" Please advice. Many thanks. Bhanu

The error message means that the problem is at linking time: the compiler is able to find the prototype of the function in one header file but when it needs to link to it, it is unable to find the function body. If this function is defined in your dll code, then you need to be absolutely sure that you added the library to your project. How did you do that ? could you explain how you added the library to your project ?
