I have a loop of code which is basically seeing if a file exists in a designated path where only the drive letter changes but never the rest of the path.

Problem is that there doesn't seem to be an easy way to determine if the path DOESN'T exist, so no processing time is wasted.

So my question is two fold -

First, is there a call I can make thatwill instantly determine if a path exists (without timing out)

and Second

If I add a Cancel button to the process which sets a cancel flag, how can I trap the flag?

(I tried putting in Application.DoEvents, but when its stuck on a directory that doesn't exist, it never catches the flag. I also tried using the Directory object and it too has a long time out..)

                        If fi.Exists = True Then
                            lvFound.Items.Add(fi.FullName)
                        End If

                        Application.DoEvents()
                        If bCancel = True Then
                            bCancel = False
                            MsgBox("Search Canceled", MsgBoxStyle.Exclamation, "Locate Files")
                            butCancel.Enabled = False
                            ssStatus.Text = ""
                            Cursor.Current = Cursors.Default
                            Exit Sub
                        End If

???

Thanks
