Dialog with custom control failed!

Anonymous — Thu, 16 Apr 2009 10:32:39 GMT

Yesterday I failed to add a custom control to a new dialog -- it didn't work and didn't even show up. In debug mode,there was no problem with dialog constructor,but pDlg->doModal() was simply skipped and OnInitDialog() was also not called.
Then i had a test on an existing dialog, which had being working with no problem, by simply adding a new custom control into it. The same problem occured again. But if i remove the custom control and rebuild it, the dialog works fine!
Has anyone tried to add a custom control before? This custom control is a MFC based grid control, and i am using VS 2002.

Hardly to say anything without piece of code.
If it is resource conflict dig CAcModuleResourceOverride class.

HavalMne:

Actually I just had a test on a sample provided in the SDK -- under directory: samples/editor/mfcsamps/modal. It's just an blank dialog with two buttons: OK and Close. I complied it and it works fine. Then i added a custom control from the Toolbox with no modification of the original codes and recompiled it. And as i expected, it failed without OnInitDialog() being called. I spent some time debugging this but no clues were found.

All my dialogs with usual MFC controls working fine.
You must check your code.

We just ran into this same problem and finally figured out the solution.

When you add the custom control to the resource file, you also have to add a member variable to the dialog class. It is not necessary to link this variable to the control--simply having it in the header file is enough to get the dialog to appear.
