Sending IDOK to a dialogbox

[MasterDucky]

I explain my problem.

I wanna make a ticker effect in a edittext field that is in a dialogbox.
Something like this:
o
lo
llo
ello
Hello etc.

Now the problem is that as long as you didnt get out of the case IDOK: you wont see anything.
You only gonna see the (whole) last phrase printed.

Now pure logic tells me that i should call IDOK with sendmessage in a loop.

But if i recall it im never gonna get out of it so its an infinite loop.

Im sure this problem has been solved already i just couldnt find it.

BOOL CALLBACK DlgProc2 (HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
    switch (message)
    {
    case WM_INITDIALOG :
        return TRUE ;
    case WM_COMMAND :
        switch (LOWORD (wParam))
        {
        case IDOK :
            Scrolling(hDlg) ;
            return TRUE ;
        case IDCANCEL :
            EndDialog (hDlg, 0) ;
            return TRUE ;
        }
        break ;
    }
    return FALSE ;
}
