Hi Gibbo,

It's certainly achievable, but how you do it depends on how the logfile is structured.
Assuming you just want to dump the whole content into the textbox, the easiest way is probably the ReadAll method for textstream files in the Scripting runtime

'a constant for the logfile path
Const LOG_FILE_PATH As String = "C:\TEMP\LOGFILE.TXT"
'add a reference to the Scipting Runtime in Tools>References
Dim fso As FileSystemObject
Dim ts As TextStream
Set fso = New FileSystemObject
    Set ts = fso.OpenTextFile(LOG_FILE_PATH)
Me.TextBox1.Text = ts.ReadAll
ts.Close
    Set ts= Nothing
    Set fso = Nothing
