Best way to trap exception if file name is in use

Hello

How can I trap the exception that occurs if the user creates a pdf and tries to create it later (perhaps having made some changes) not realizing the first copy is open in the Acrobat viewer?

Thanks.

Rob.

Can someone let me know when this bug has been fixed?

Thanks.

Rob

Thank you Julian.

I have modified the code in WPtoPDFDlg to see if the file can be exclusively opened when the user clicks 'CreatePDF'.

Try
    if FileExists(fileName.text) Then
      begin
        chkStream := TFileStream.Create(fileName.text, fmOpenReadWrite OR fmShareExclusive);
      end;
  except
    on EFOpenError do
    .....

I will look at your suggestion but the I'm sure error being returned was an IO error.

Rob.
