The sample goes. Resource only DLL includes IDD_YOUR dialog template. Regular DLL includes IDD_MY dialog template, but implements both classes, CMyDialog and CYourDialog. Hope this close enough to what you're trying to implement.
Thanks for your sample. Actually CMyDialog and CYourDialog are defined in two different dll. Basically what happens is that an exe launches CMyDialog defined in MyDll.dll and then when CMyDialog is NOT dismissed, CYourDialog is launched from defined in YourDll.dll. I would really appreciate it if you can post a sample by using MFC. Thank you very much!
