Question

Hi I would like to know how i can write to the following file C:test.txt a specific string of text like “LANDSCAPE” if a radiobutton is clicked?

If you simply want to create a file containing nothing but the text “LANDSCAPE”, and you want to overwrite the file by that name if it already exists, then all you need to do is:

Private Sub RadioButton1_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles RadioButton1.CheckedChanged
    If RadioButton1.Checked Then
        File.WriteAllText("C:\test.txt", "LANDSCAPE")
    End If
End Sub
