[RESOLVED] Another Logic Question: Button Control Only To Fire Once.

[Morbane]

Well I have a Dialog with all kinds of things going on but for this question it regards a single Button Control. I would like the user to be able to use this button only once. It is pretty basic, but using a simple BOOL does not seem to do the trick - or at least how I have tried it.

My version:

//Reset Button
case IDC_BTN_RSTR:
{
     BOOL var = TRUE;
     if(var == FALSE) return TRUE;
     SetDlgItemInt(hwndDlg, IDC_STR, 0, FALSE);
     SetDlgItemInt(hwndDlg, IDC_STR_, 0, FALSE);
     SetDlgItemInt(hwndDlg, IDC_STR__, 0, FALSE);

     var = FALSE;
     return TRUE;
}
