GetDlgItem IDC_PAINT error
I'm trying to retrieve a handle to the window to
update it with the following call in the callback
procedure for my dialog box :
hCtrlBlock = GetDlgItem (hDlg, IDC_PAINT) ;
But get the following error :
error C2065: 'IDC_PAINT' : undeclared identifier

anyone know what I'm doing wrong?
