bad file name or number

[cvirendra]

Hi all,

M using visual basic 2005. I have declared a variable Log_File as integer in a module.

I've open a file using openfile in a function (which is again defined in the same module). M using a Print function to write inot the file. When i call Print function within same moude it works fine. But if i call Print from a event in form, i m gettin bad ile name or number exception.

Can anyone help me. Wat m i missin her?

Thanks in advance

Thankx for d reply...

the code dat works is

Public Sub processSend(ByVal message As String, ByVal port As String)
        System.Threading.Thread.Sleep(50)
        My.Forms.frmMain.serialPort.Write(message & vbCrLf)
        Last_Sent_Time = GetTickCount()
        Print(Log_File, Last_Sent_Time & "@" & message & vbCrLf)
End Sub

I m callin dis function whenever I hv a data to b sent 2 d serial port. Also this function is defined in a module.

Now on the frmMain form I have a serialport control. On the recieve event i hv written d followin code..

Private Sub serialPort_DataReceived(ByVal sender As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles serialPort.DataReceived
 
        Dim ReceiveTimeStamp As Long
 
        ReceiveTimeStamp = GetTickCount()
 
        If (Look_Buffer_Count >= 19) Then
            Look_Buffer_Count = 0
        Else
            Look_Buffer_Count = Look_Buffer_Count + 1
        End If
 
 
        Look_Buffer(Look_Buffer_Count) = ReceiveTimeStamp & "@" & Me.serialPort.ReadLine
 
        If (Start_Logging = True) Then
            'Call updateLogFile(ReceiveTimeStamp & "@" & Look_Buffer(Look_Buffer_Count))
            Print(Log_File, Look_Buffer(Look_Buffer_Count))
        End If
End Sub

Here while executin line "Print(Log_file......" i get bad file name or number exception.

Hope dis clear d problem 2 u.

Have you checked what the value is in Log_File when it works, and when it doesn't?

Yes! It is the same both d times ...

Yes! It is the same both times ...

Damn! :(

Not being familiar with VB.Net, I'm pretty much out of ideas.

That does not make sense. Either the file has been closed, not opened yet, or out of scope. We need to know the scope of Log_File and where and when it is given a file handle.
