Custom Controls in MFC

[Paul Groetzner]

Hello all, I am trying to create a custom control but I have a major problem I haven't been able to resolve. The issue is this: If I introduce a customer control using the resource editor to a new or an existing dialog box, that specific dialog will cease to appear when the program is run (or the app won't run if it happens to be within the main dialog box). If I delete the control, everything works fine again and the dialog box will once again appear. Could someone please assist? This has been puzzling me for quite some time. I'm using VC++ 2005. To replicate, create a new dialog based application. Run it to see the default dialog box appear, then exit. Drag a custom control from the toolbox into the main dialog box. Run it again. If you can get the dialog box to appear even if the control doesn't do anything yet, let me know what you did! Thanks!!!!!

You have to provide a window class name that has been registered (through AfxRegisterClass function). Take a look at this article[^] for an example. If you don't follow this step, there won't be any window procedure associated with the control and the creation of the dialog will fail.

Can you add the DS_NOFAILCREATE style (until you resolve the problem)? Do you get any output in the debug window (e.g, failed to load xyz.dll)?

Call the Following Method to enable the custom containers in the application where you are using the custom controls

AfxEnableControlContainer();
