vb中mouse_event问题

给你写了一个示例，你自己可以看明白的：

Private Declare Sub mouse_event Lib "user32" (ByVal dwFlags As Long, ByVal dx As Long, ByVal dy As Long, ByVal cButtons As Long, ByVal dwExtraInfo As Long)
Private Const MOUSEEVENTF_ABSOLUTE = &H8000 '指定鼠标使用绝对坐标系，此时，屏幕在水平和垂直方向上均匀分割成65535×65535个单元
Private Const MOUSEEVENTF_MOVE = &H1 '移动鼠标
Private Const MOUSEEVENTF_LEFTDOWN = &H2 '模拟鼠标左键按下
Private Const MOUSEEVENTF_LEFTUP = &H4 '模拟鼠标左键抬起

Private Const SW = 1024
Private Const SH = 768

Private Sub Screen_Click(ByVal x As Long, ByVal y As Long)
mw = x / SW * 65535
mh = y / SH * 65535
mouse_event MOUSEEVENTF_ABSOLUTE + MOUSEEVENTF_MOVE, mw, mh, 0, 0
mouse_event MOUSEEVENTF_LEFTDOWN Or MOUSEEVENTF_LEFTUP, 0, 0, 0, 0
End Sub

Private Sub Command1_Click()
Screen_Click 512, 384 '点击Command1之后，模拟点击屏幕中间
End Sub

Private Sub Command2_Click()
Print Rnd
End Sub
