Winforms? Try handling the key up event of textbox, break the text into lines

Dim Lines As String() = txtInput.Text.Split(VBCRLF)

Then check if any of the lines is beyond the maximum then either strip it out show an error

For Each Line In Lines
   If Line.Length > 10 Then
      msgbox "Error"
   End If
End If
0
