IO Error 32 when dealing with FileListBox, DirListBox, DriveCombo

In my app i have TabSheet where i have 3 group boxes, every group box
contains a set of FileListBox, DirListBox and DriveCombo.

When i am starting two copies on my app on the same computer, i sometimes
having IO Error 32 which means that file is locked by another process..

What does it means and how i can disable that?

TIA,
Eugene.

It means that your app is probably trying to access a file that is
already in use. Usually you will get this when trying to open the
file. But you should be able to compile your app, run it from outside
the ide, and then run another copy from inside the IDE with break on
exception set. Then you'll know exactly what code is causing the
problem.

Good luck.

no i am not opening any file at all. I think this is caused by FileListBox
components.

It means what it says, nothing more, nothing less. You would get that if
your application opened a file in exclusive mode and the second instance
tries to open the same one. Just displaying the available files in the
filelistbox will not open any of them, so not cause the problem. It has to
be something you are doing in your code.

That is what *you* are thinking <g>. Honestly, i cannot think of a reason why
just using the set of components you use would cause that kind of error.
