Is it possible to create a MFC extension dll with dialog in itand call the dll from the exe dialog frame to display the dlldialog inside the exe dialog?
Here's an example of possible unnecessary complexity. Can you explain why you need a nested child dialog within your main dialog? And, why the child dialog needs to live in another dll? Keep in mind, you're seeking help from other developers who have no idea what your application design consists of. Rather than asking short ambiguous questions, it is better to provide some background information and sample code (when necessary) so we can get a clear picture of what you are doing.
