PrintDialog problem
>> We are experiencing a really bad problem. We can't get either the PrintDialog or
PrinterSetupDialog boxes to work more than a couple of times. We have both a menu choice
and a speedbutton that runs the execute method of each dialog. After one or two times of
executing neither one will work. When we issue execute, nothing happens. This happens on
three different PCs all running Windows for Workgroups.
Some patches to work around the problem:
In DIALOGS.PAS, change
{ 1530 } hWndOwner := Application.Handle;
{ 1531 } if TaskModalDialog(@PrintDlg, PrintDlgRec) then
{ 1532 } SetPrinter(hDevMode, hDevNames)
{ 1533 } else
to
{ 1530 } hWndOwner := Application.Handle;
{ 1531 } SetPrinter(hDevMode, hDevNames);
{ 1532 } if not TaskModalDialog(@PrintDlg, PrintDlgRec) then
and
{ 1582 } if Result then
{ 1583 } begin
{ 1584 } SetPrinter(hDevMode, hDevNames);
{ 1585 } F := Flags;
to
{ 1582 } SetPrinter(hDevMode, hDevNames);
{ 1583 } if Result then
{ 1584 } begin
{ 1585 } F := Flags;
You also need to call the following routine once, before invoking either the print or printer
setup dialogs:
procedure InitPrinter;
var
Device, Driver, Port: array[0..79] of Char;
DevMode: THandle;
begin
GetPrinter(Device, Driver, Port, DevMode);
SetPrinter(Device, Driver, Port, DevMode);
end;
