c# 使用winapi点击第三方程序中的toolstrip

点击button可以用sendmessage来完成,但是toolstrip只能获取到整体的句柄,里面的按钮却获取不到,因此使用移动鼠标并点击的方法来模拟完成。
使用到的api定义:

        [DllImport("user32")]
        private static extern int mouse_event(int dwFlags, int dx, int dy, int cButtons, int dwExtraInfo);

        const int MOUSEEVENTF_LEFTDOWN = 0x0002;
        const int MOUSEEVENTF_LEFTUP = 0x0004;

        [DllImport("user32.dll")]
        static extern bool SetCursorPos(int X, int Y);

        [DllImport("user32.dll")]
        private static extern bool SetForegroundWindow(IntPtr hWnd);

        [DllImport("user32.dll")]
        private static extern int GetWindowRect(IntPtr hwnd, out Rect lpRect);

        [DllImport("user32.dll")]
        public static extern bool GetCursorPos(out Point pt);       

   public struct Rect
        {
            public int Left;
            public int Top;
            public int Right;
            public int Bottom;
        }

获取toolstrip的矩形,这个得到的是屏幕位置。

 GetWindowRect(_toolbar, out rect);

移动并点击:

            int y = rect.Top + int.Parse(txtTop.Text);
            int x = rect.Right - int.Parse(txtRight.Text);

            SetForegroundWindow(_mainWin);
            SetCursorPos(x, y);
            mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0, 0);
            mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0, 0);

x,y是针对toolstrip矩形的right和top的偏移量。
