Simple and short guidelines:

1. Place a TOpenDialog widget on your form. It can be placed anywhere on your form as it is not visible during program run time but only during design time.

It is located in the Dialogs tab of the component palette and is the leftmost component.

2. In your code write something similar to:

if OpenDialog1.Execute then
  begin
    if fileExists(OpenDialog1.Filename) then
      ShowMessage(OpenDialog1.Filename);
  end
else
  ShowMessage('No file selected');

The dialog Execute method displays the file open dialog. It returns true when user has selected a file, false when user has aborted.

The dialog Filename property returns the full filename including drive and path.

  Note: This control only collects the filename. It does not actually open the file. Your code must do that.
