VB编写，使文本框里的文本自动向上滚动。

画个timer,设置interval=100,再画个文本框,加点内容
=====================================
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

Private Sub Timer1_Timer()
SendMessage Text1.hwnd, 277, 1, 0
End Sub
