I know this may be an old thread, but I thought I'd answer it just in case anyone else stumbled across it.

First declare the following (you may need to import System.Runtime.InteropServices)

<DllImport("user32.dll", CharSet:=CharSet.Auto)> _
Private Shared Function SendMessage(ByVal hWnd As IntPtr, ByVal msg As Integer, ByVal wParam As Integer, <MarshalAs(UnmanagedType.LPWStr)> ByVal lParam As String) As Int32
End Function

Then call the following (change as needed):

SendMessage(Me.textbox1.Handle, &H1501, 0, "Enter User name here")

Assuming you mean Windows Forms, take a look at this question.
Basically, you need to call a WinAPI SendMessage function for the control with EM_SETCUEBANNERvalue.
