C#和C常用的API操作窗口的代码积累

IntPtr awin = MouseHookHelper.FindWindow("WeChatMainWndForPC", "微信");
if (awin == IntPtr.Zero)
{MessageBox.Show("没有找到窗体");return;
}
2.获取窗体坐标信息
MouseHookHelper.RECT rect = new MouseHookHelper.RECT();
MouseHookHelper.GetWindowRect(awin, ref rect);
int width = rect.Right - rect.Left;             //窗口的宽度
int height = rect.Bottom - rect.Top;            //窗口的高度
int x = rect.Left;
int y = rect.Top;
3.设置为当前窗体
MouseHookHelper.SetForegroundWindow(awin);
MouseHookHelper.ShowWindow(awin,MouseHookHelper.SW_SHOWNOACTIVATE);//4、5
4.点击某个坐标
LeftMouseClick(new MouseHookHelper.POINT()
{X = ppp.MsgX,Y = ppp.MsgY
});private static void LeftMouseClick(MouseHookHelper.POINT pointInfo)
{//先移动鼠标到指定位置MouseHookHelper.SetCursorPos(pointInfo.X, pointInfo.Y);//按下鼠标左键MouseHookHelper.mouse_event(MouseHookHelper.MOUSEEVENTF_LEFTDOWN,pointInfo.X * 65536 / Screen.PrimaryScreen.Bounds.Width,pointInfo.Y * 65536 / Screen.PrimaryScreen.Bounds.Height, 0, 0);//松开鼠标左键MouseHookHelper.mouse_event(MouseHookHelper.MOUSEEVENTF_LEFTUP,pointInfo.X * 65536 / Screen.PrimaryScreen.Bounds.Width,pointInfo.Y * 65536 / Screen.PrimaryScreen.Bounds.Height, 0, 0);}
5.复制粘贴操作
//复制到剪贴板
Clipboard.SetText("test");
//从剪贴板获取数据
Clipboard.GetText();
//粘贴
SendKeys.SendWait("^V");
//回车键
SendKeys.Send("{Enter}");
6.钩子的使用
private void button1_Click(object sender, EventArgs e)
{if (hHook == 0){MyProcedure = new MouseHookHelper.HookProc(this.MouseHookProc);//这里挂节钩子hHook = MouseHookHelper.SetWindowsHookEx(WH_MOUSE_LL, MyProcedure, Marshal.GetHINSTANCE(Assembly.GetExecutingAssembly().GetModules()[0]), 0);if (hHook == 0){MessageBox.Show("请以管理员方式打开");return;}button1.Text = "卸载钩子";}else{bool ret = MouseHookHelper.UnhookWindowsHookEx(hHook);if (ret == false){MessageBox.Show("请以管理员方式打开");return;}hHook = 0;button1.Text = "安装钩子";}
}private int MouseHookProc(int nCode, IntPtr wParam, IntPtr lParam)
{MouseHookHelper.MouseHookStruct MyMouseHookStruct = (MouseHookHelper.MouseHookStruct)Marshal.PtrToStructure(lParam, typeof(MouseHookHelper.MouseHookStruct));if (nCode < 0){return MouseHookHelper.CallNextHookEx(hHook, nCode, wParam, lParam);}else{String strCaption = "x = " + MyMouseHookStruct.pt.X.ToString("d") + "  y = " + MyMouseHookStruct.pt.Y.ToString("d");this.Text = strCaption;return MouseHookHelper.CallNextHookEx(hHook, nCode, wParam, lParam);}
}
