vb.net 模拟 Win + D 显示桌面

显示桌面的本质是个系统 Shell(IShellDispatch4.ToggleDesktop()),所以只需要调用这个 Shell 就好了,用不着模拟按键。

CType(objShel, Shell32.IShellDispatch4).ToggleDesktop()

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
