title: Create a textbox "hint" message for two different textboxes(watermark)
body: <p>I was wondering how to create a "hint" for two different textboxes in a form?</p>
  
  <p>Here is the code I have:</p>
  
  <p><code>Imports System.Runtime.InteropServices</code></p>
  
  <p><strong>Form_Load Event:</strong></p>
  
  <pre><code>SendMessage(Me.txtAmount.Handle, &amp;H1501, 0, "$X.XX")
  SendMessage(Me.txtMemo.Handle, &amp;H1501, 0, "Enter a transaction memo.")
  </code></pre>
  
  <hr>
  
  <p><strong>Shared Function:</strong></p>
  
  <pre><code>&lt;DllImport("user32.dll", CharSet:=CharSet.Auto)&gt; _
      Private Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal msg As Integer, ByVal wParam As Integer, &lt;MarshalAs(UnmanagedType.LPWStr)&gt; ByVal lParam As String) As Int32
      End Function
  </code></pre>
  
  <p>This code is only working for the <code>txtAmount</code> textbox.  Any idea how to get two working in one form?</p>
  
  <p>Thanks.</p>
