TPrinter and net printers

Hi,
I use TPrinter to create a custom report, but when I select a net
printer different than default printer, my report is printed on default
printer -_-
//------------------------------------
TPrinter *printer = new TPrinter;
if (PrintDialog->Execute())
{
printer->BeginDoc();
//code to fill canvas
printer->EndDoc();
}
delete printer;
//------------------------------------
What about this problem? Any suggest is welcome!

Use the API function EnumPrinters to get the name, etc. of the printer

you want. Use this name as an argument to the TPrinter->SetPrinter
function.

Please show the code where you choose the printer.

TPrinter *printer = new TPrinter;
You are not supposed to do that.

Use
TPrinter *printer = TPrinter();
instead. And do not delete.

The user chooses with TPrintDialog a printer. The printer

then is set bij the PrintDialog. So you do not
need to set the printer yourself.
RichEdit1->Print() wil print to the selected printer then.
And Printer()->.... too.

I never use that dialog myself. I assign the list of printers

to a ComboBox:
prnComboBox->Items->Assign( Printer()->Printers );
and then use it's item index as the value that should be assigned to the printer index:
Printer()->PrinterIndex = prnComboBox->ItemIndex;
If the user doesn't select a printer from the ComboBox, it's
item index will be -1 which translates to the default printer.

Ok... this is a possibility... but what about using TPrinterDialog?

What about it? It doesn't give you anything that you can't

easily do yourself. Granted, using the dialog means that you
don't have to code (much of) anything but it also means that
you have to use a GUI designed by someone else.

I like to know how I can retrieve printer selected by a TPrinterDialog

and assign it to TPrinter object, in order to print on any other net
printer and not only on default printer.

You were already told that the by the user selected printer is

automatically assigned as default printer for TPrinter().
So this was twice.

No... Even if I chose another printer by TPrinterDialog, TPrinter use

default printer because I can't set the TPrinter->PrinterIndex property.

No it does not. And you do not have to set PrinterIndex. And of course

you can always set PrinterIndex as that has nothing to do wit TPrintDialog.
Please show your code now.

In TPrinterDialog I can choose a net printer, but I don't select any
printern in my TPrinter object, so I finally print on default printer. I
would like to retrieve the printer that I've selected by TPrinterDialog
and assign it to TPrinter

Hans already told you to not 'new' the printer. Just use the

global Printer() object instead:
Printer()->BeginDoc();
