Note that you must call SetWindowLong immediately before returning TRUE; doing so earlier may result * in the DWLP_MSGRESULT value being overwritten by a nested dialog box message. * * [...] * * Remarks * ======= * You should use the dialog box procedure only if you use the dialog box class for the dialog box. This is the default * class and is used when no explicit class is specified in the dialog box template. Although the dialog box procedure * is similar to a window procedure, it must not call the DefWindowProc function to process unwanted messages. Unwanted * messages are processed internally by the dialog box window procedure. * */
