FilsSystemObject not finding file that is clearly there.

[cdck]

I have a program which creates a batch file, runs it, and then manipulates the files the batch file causes to be output. When it gets to the point where it's supposed to open and manipulate those files, it gives me an error telling me that the first file does not exist. If I navigate to the folder in which the file should be found (In this case, C:\ECDIS\FULLtest\PROC\OUTDB.txt) the file is sitting right there.

Can anyone see the problem with the code below? I start at the point where the batch file is created and then run, and end on the line which throws the error.

        'Create the batch file to process the data and then run it.
        Dim BatFile
        Dim BasePath As String = Me.lblRoot.Text & "ECDIS\"

        If Not objFSO.FileExists(Me.lblRoot.Text & "ECDIS\" & Me.txtSN.Text & "\RAW\BATCH.bat") Then
            BatFile = objFSO.CreateTextFile(Me.lblRoot.Text & "ECDIS\" & Me.txtSN.Text & "\RAW\BATCH.bat")
        Else
            objFSO.DeleteFile(Me.lblRoot.Text & "ECDIS\" & Me.txtSN.Text & "\RAW\BATCH.bat")
            BatFile = objFSO.CreateTextFile(Me.lblRoot.Text & "ECDIS\" & Me.txtSN.Text & "\RAW\BATCH.bat")
        End If

More info:

If I run the same process a second time without deleting the files the first pass created, it finds them and processes them without error.

If I go back and delete those files and try again - error again.

Ignore this thread. I added a 1-second wait after the batch file runs before it continues the process, and now it fires fine. Apparently things were just moving too fast for the system to give accurate information.
