I'm looking for a simple way to open a text file and search for any 8 characters and ".exe"

Then it should display whatever the 8 characters are.

End Sub

Hope this starts you off.

Sorry, I think this is what you meant

Option Explicit

Private Sub Form_Load()
Dim lin As Long, col As Long, sdata As String

If CheckFile("c:\test\test.txt", ".exe", lin, col, sdata) Then
    Debug.Print sdata
End If


End Sub


Public Function CheckFile(sFilePath As String, ByVal sSearch As String, lin As Long, col As Long, sdata As String) As Boolean

    Dim i As Long, sline
    i = FreeFile
    lin = 0
   
   
    Open sFilePath For Input As i
    While Not EOF(i)
        Line Input #i, sline
        lin = lin + 1
        If InStr(sline, sSearch) > 8 Then
            col = InStr(sline, sSearch)
            sdata = Mid(sline, col - 8, 8)
            Close i
            CheckFile = True
            Exit Function
        End If
    Wend
   
    Close i
   


End Function
