vb中用RichTextBox控件怎样和Timer控件联系制作出
文档自动滚屏啊？
我找了点代码但只是点一个按钮向下挫一行，但不能自动向下移动！
代码：
Const EM_LINESCROLL = &HB6
Private Declare Function SendMessageBynum Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As Long) As Long
Private Sub Command20_Click()
SendMessageBynum RichTextBox1.hwnd, EM_LINESCROLL, 0, 1
' 下卷一行
End Sub
Private Sub Timer1_Timer()
'文字滚动
SendMessageLong RichTextBox.hwnd, EM_LINESCROLL, 0, 1
End Sub
能不能帮我将RichTextBox控件和Timer控件联系起来！！！
谢了！！！
