程序控制开始菜单的弹出 C#

基本思路为，寻找开始菜单按钮窗口，并模拟用户单击
void pop() { User32.EnumWindows(new EnumProc(Enum), 0); } private bool Enum(IntPtr hWnd, uint param) { User32.STRINGBUFFER buffer=new User32.STRINGBUFFER(); User32.GetClassName(hWnd, ref buffer, 256); if (buffer.szText == "Shell_TrayWnd") { User32.EnumChildWindows(hWnd, new EnumProc(Enum2), 0); return false; } else return true; } IntPtr lastForeGroundWindow; private bool Enum2(IntPtr hWnd, uint param) { User32.STRINGBUFFER buffer = new User32.STRINGBUFFER(); User32.GetClassName(hWnd, ref buffer, 256); if (buffer.szText == "Button") { if (User32.SendMessage(hWnd, WndMsg.BM_GETSTATE, 0, 0) == User32.BST_PUSHED) { User32.SetForegroundWindow(lastForeGroundWindow); } else { lastForeGroundWindow = User32.GetForegroundWindow(); User32.SetForegroundWindow(hWnd); User32.PostMessage(hWnd, WndMsg.BM_CLICK, 0, 0); } return true; } else return false; }
