I have the following unmanaged C++ code:

MessageBox( NULL, strMessage, "Cool Product", MB_RETRYCANCEL | MB_ICONEXCLAMATION);

I want to disable the RETRY button for 10 seconds (for example), then enable it.

How can I do this?

You cannot (or I am not aware) do this with a message box. You have to create a custon dialog, or easiest yet... Creat a form that represents a dialog-box, with the border style as dialog... The rest should be easy... If the form should return a result, a custom dialog is best... Otherwise, a standard form should do the trick... (This is how I do it, anyway!)

Can you point me in the direction of a tutorial on how to do this? I want to avoid MFC and ATL and use only standard Win32 API calls.

You could start a thread which for example calls FindWindow(NULL, "Cool Product") to retrieve the handle of the message box (dialog) window. Then, call GetWindow to iterate the child windows of the message box. One of them - most probably - is the Retry button (you may call GetWindowText to retrieve the button's text for identification). You can retrieve its dialog item ID by calling GetDlgCtrlID. If you once know the ID you could get the button's window handle by calling GetDlgItem(hwndMBox, idRetryButton);


Then

   EnableWindow(hwndRetry, FALSE);
   Sleep(10000);
   if (IsWindow(hwndRetry))
       EnableWindow(hwndRetry, TRUE);

should do what you intend.
