Howto Use TOpenDialog
Simple and short guideline:
1. Place the OpenDialog widget on your form (anyplace, since it will be not visible).
(It is the left most dialog under Dialog)
2. In your code write something similar to:
var
filename: string;
if OpenDialog1.Execute then
begin
filename := OpenDialog1.Filename;
ShowMessage(filename);
end;The Execute method displays the file open 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.
