You will need to import System.IO, if not already imported.

I am just learning vb, but I came across this that might work -

Dim ff As Integer
On Error GoTo errHandler

ff = FreeFile
Open "c:\sample.txt" For Random Access Write As #ff
Close #ff

errHandler:
    MsgBox "File is Open"

Hello madhatter5501

While i have no intention to discourage your attitude to be helpful, may i bring it to your attention that this question is being asked in Microsoft Visual Basic.NET zone and your answer caters to Microsoft Visual Basic 5.0 / 6.0, the older versions prior to .NET.
