VB.NET模拟鼠标问题
Declare Sub mouse_event Lib "user32" Alias "mouse_event" (ByVal dwFlags As Integer, ByVal dx As Integer, ByVal dy As Integer, ByVal cButtons As Integer, ByVal dwExtraInfo As Integer)
Dim postion1 As New Point
mouse_event(H1 Or H8000, postion1.X * 65535 / 1366, postion1.Y * 65535 / 768, 0, 0)
'按绝对位置移动鼠标
'在鼠标坐标系统中,屏幕在水平和垂直方向上均匀分割成65535×65535个单元,
'当前所用显示屏分辨率为1366*768
'所以要进行如上转换
mouse_event(H2, 0, 0, 0, 0) '鼠标左键按下
mouse_event(H4, 0, 0, 0, 0) '鼠标左键弹起
msdn上有 mouse_event 的详解,大致使用如上
