Description

TSaveDialog displays a modal Windows dialog box for selecting file names and saving files. The dialog does not appear at runtime until it is activated by a call to the Execute method. When the user clicks Save, the dialog closes and the selected file name is stored in the FileName property.

Delphi Examples:

Copy Code

{
This example reads an entire file into a buffer with one
command and then writes it into a saved file.  Validate
the saved file contents.
}
procedure TForm1.Button1Click(Sender: TObject);
var
  FromF, ToF: file;
  NumRead, NumWritten: Integer;
  Buf: array[1..2048] of Char;
begin
  if OpenDialog1.Execute then     { Display Open dialog box }
  begin
    AssignFile(FromF, OpenDialog1.FileName);
    Reset(FromF, 1);    { Record size = 1 }
    if SaveDialog1.Execute then      { Display Save dialog box}
    begin
      AssignFile(ToF, SaveDialog1.FileName);    { Open output file }
      Rewrite(ToF, 1);  { Record size = 1 }
      Canvas.TextOut(10, 10, 'Copying ' + IntToStr(FileSize(FromF))
        + ' bytes...');
      repeat
        System.BlockRead(FromF, Buf, SizeOf(Buf), NumRead);
        BlockWrite(ToF, Buf, NumRead, NumWritten);
      until (NumRead = 0) or (NumWritten <> NumRead);
      // Use CloseFile rather than Close; Close provided for backward compatibility
      CloseFile(FromF);
      CloseFile(ToF);
      Canvas.TextOut(120, 10, ' done.');
    end;
  end;
