Private Const WM_SETTEXT = &HC
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As System.Text.StringBuilder) As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim s As String = "王小明"
Dim build As New System.Text.StringBuilder(s.Length)
build.Append(s)
SendMessage(TextBox1.Handle, WM_SETTEXT, 0&, build)
End Sub
