I presume you know how to read text from a file, if not search for "read text from a file" in help

the code below uses a variation of select you may not have tried

Select Case True

which allows you to put a boolean expression in each Case statement.

Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
        Dim LineIn As String
        LineIn = ""

        'open and loop through file one line at a time reading line into variable LineIn
        'below is the code to extract the data you are interested in and display it in a 
        'series of labels on the form you have set up for the purpose
        Select Case True
            Case InStr("Convergence Iterations", LineIn) <> 0
                Label1.Text = LineIn
            Case InStr("Number of Stations", LineIn) <> 0
                Label2.Text = LineIn
                ' etc ...
        End Select

    End Sub
