Problem with SelectDirectory Function

Posted on 2002-04-16
Last Modified: 2010-04-04
  When the user calls the SelectDirectory function in my app, I want it to default to the root directory (ie. C:\)... but it won't do it. Here's my code:

if SelectDirectory(defdir,[],0) then
else speedbutton21.hint:='';

...the SelectDirectory dialog box always comes up with the directory my app is located in, as its selected directory...weird. There seems to be no way I can force it to go to the root directory.

Any thoughts?

You could do it like this:

procedure TForm1.Button1Click(Sender: TObject);
  DefDir : string;
  if SelectDirectory('Please choose a directory:', 'C:\', DefDir) then
    speedbutton21.hint := DefDir
    speedbutton21.hint := '';

It works if you initialize defdir to "c:\*.*"

P.S. It seems to be a small bug in FileCtrl.ProcessPath

that gives a complile error:

"Constant object cannot be passed as var parameter"

I don't think it likes the 'Please choose a directory''s expecting a variable.
