    Dialog box focus

    Hello,
    I am writing a program using VC++ with MFC,
    I added some dialog boxes and I want that once one of the dialog is opened by DoModal()
    all the buttons on the parent dialog will be disabled,
    How can I do it?


    thanks

    What's the point in that? DoModal will prevent the user from accessing all other windows anyway.

    Sometimes it looks nice

    With GetWindow you can enumerate all the children of the dialog, and with IsKindOf you can check if the childwindow is a CButton and en/disable it. With these 2 you can make a loop that loops all the elements on a dialog and set the buttonstate.

    I'd suggest checking windows class (using GetClassName) rather than MFC class because there may be unsubclassed buttons.

    Again though, what's the point in disabling buttons you can't click on anyway?

    I don't know! Perhaps, OP would like to see all these buttons as disabled!?

    I agree with GCDEF. It's more user-friendly to let an application behave as most other applications do. Otherwise, it's just confusing. Users may think there is something wrong with the application just because a button is disabled when they didn't expect it.
