Howto Use TSaveDialog
Simple guideline:
1. Place the SaveDialog widget on your form (anyplace, since it will be not visible).
(It is the second left dialog under Dialogs tab)
2. Add a memo in the form.
3. Add a button in the form.
The Object Inspector will display the properties of the object Button1. Change a property named 'Caption', with the displayed value 'Button1' to 'Save'. Click on the Events tab on the Object Inspector.Select the box to the right of OnClick: a smaller box with three dots (... ellipsis) appears. Click on this, you are taken automatically into the Source Editor and your cursor will be placed in a piece of code starting. Completion code:
procedure TForm1.Button1Click( Sender: TObject );
begin
if SaveDialog1.Execute then
Memo1.Lines.SaveToFile( SaveDialog1.Filename );
end;The Execute method displays the file save dialog. It returns true when user has selected a file, false when user has aborted.
The Filename property returns the full filename including drive and path
