    Hi group,
    I want to get the printer information using TPrinterInfo2
    when I call the API function GetPrinter x is 67 that means 67 bytes are
    copied
    But when I access any record var of TPrinterInfo2 I get the access
    violation.
    What I am missing. Keep in mind pointer always pintches me a lot. So, Please
    put me an example instead of hind if you can!

    Thanks in advance.

    =================================================
    Here is my code:

    procedure TfmPSetup.Button1Click(Sender: TObject);
    var
      PInfo: TPrinterInfo2;
      x: Word;

    begin
      WinSpool.GetPrinter(Printer.Handle, 2, @PInfo, SizeOf(PInfo), @x);

      // always access violation here, whatever I access the record variable
      // I have read in the help that PChar can be typed-cast into string so I
    did.
      ShowMessage(string(PInfo.pLocation));
    end;
    =================================================
