GeneralProblems with MFC Extensions DLLs Pin

Dear sirs !
I ask you kindly to help me with my problem. I want to understand the reason of the problem I see. I use VC++ 6.0 with SP 5, OS Windows 2000 Professional.

I create two MFC Extension DLLs. The first of them exports class CMyClassA. The other one exports CMyClassB. Each of the classes uses it’s own resources, for example Dialogs.
CMyClassA::ShowDialog() method shows a DialogA.
CMyClassB::ShowDialog() method shows a DialogB.

Next step.
I want to import these 2 classes from DLLs to my new Project, let it be SDI-application. I create it using MFC AppWizard(exe). I link *.lib files to the project.
When I import ONLY CMyClassA, or ONLY CMyClassB, everything is fine, everything works perfectly as I need. As soon as I import both CMyClassA and CMyClassB to the same application, problems are coming. These two classes begin to conflict by their resources. So I can’t call methods ShowDialog() for any of them. Instead of result I see something like this: “An unsupported operation was attempted”.
What’s wrong with these DLLs can be ? How to solve the problem of resources conflict between DLLs ?

I would be very grateful for your help.


Best regards, Alexander.
