Using SendMessage to simulate mouse clicks
提问by Doon
What I need
我需要的
Simulate messages (mouse mainly, but keyboard too) without moving the cursor. The message goes to the focused window (at first, I want for minimized windows, but I didn't find how to do it, so I use SetForegroundWindowto focus it).
在不移动光标的情况下模拟消息（主要是鼠标，但也包括键盘）。消息进入聚焦窗口（起初，我想要最小化窗口，但我没有找到如何去做，所以我SetForegroundWindow用来聚焦它）。
What I've found
我发现了什么
On thisquestion, I've figured out I need to use pInvoked from user32.dll. Also I found a small code sample, but it didn't work.
在这个问题上，我发现我需要使用 pInvoked from user32.dll。我还发现了一个小代码示例，但没有用。
I also found thissimilar question. The guy uses mouse_event, but it is deprecated. This function takes the X and Y cordinates in mickeys. I tried to convert my coordinates (using SendMessage), but I failed.
我也发现了这个类似的问题。这家伙使用mouse_event，但它已被弃用。此函数采用米奇中的 X 和 Y 坐标。我试图转换我的坐标（使用SendMessage），但我失败了。
Icanhaz an example?
伊坎哈兹举个例子？
Sure. The notepad.exeis opened and I need to peform a right click on a button located at (1210, 460).
当然。将notepad.exe被打开，我需要对[执行位于（1210，460）按钮右键单击。
What I've tried
我试过的
Based on the sample that I've found here, I did this code:
根据我在此处找到的示例，我执行了以下代码：
IntPtr hWnd = (IntPtr)FindWindow("notepad.exe", null);
SetForegroundWindow(hWnd);
var screenPoint = this.PointToScreen(new Point(1210, 460));
var handle = WindowFromPoint(screenPoint);
if (handle != IntPtr.Zero)
{
//Right Button Down
SendMessage(handle, 0x0204, IntPtr.Zero, IntPtr.Zero);
//Right Button Up
SendMessage(handle, 0x0205, IntPtr.Zero, IntPtr.Zero);
}
I also tried using my previous handle hWndin SendMessage, but didn't work as well. The whole code you can find here.
我用我以前的手柄也试过hWnd在SendMessage，却没有正常工作。你可以在这里找到完整的代码。
Thank you in advance.
先感谢您。

Raymond Chen wrote a blog post just for you: You can't simulate keyboard input with PostMessage. I know you want mouse, not keys, and you use Send not Post, but exactly the same problems apply to you. Read the link. Fortunately, it also contains the solution: use SendInputfunction.
Raymond Chen 专门为您写了一篇博文：您无法使用 PostMessage 模拟键盘输入。我知道您需要鼠标而不是键，并且您使用的是发送而不是邮寄，但同样的问题也适用于您。阅读链接。幸运的是，它还包含解决方案：使用SendInput函数。
Synthesizes keystrokes, mouse motions, and button clicks.
合成击键、鼠标动作和按钮点击。

This is some mouse and keyboard handler ive made when I was younger to find a color on a game screen and click ||right click+option :P
这是我小时候在游戏屏幕上找到颜色并单击 || 右键单击+选项时制作的一些鼠标和键盘处理程序：P
Maybe some of the code may help you even if it's in french...
也许一些代码可以帮助你，即使它是法语......

If I corectly understand, you want to inject a click event inside an application without having to move the mouse, like a game bot, so the user don't see sumthing is using his mouse and keyboard...
如果我正确理解，您希望在无需移动鼠标的情况下在应用程序中注入一个点击事件，就像游戏机器人一样，这样用户就看不到 sumthing 正在使用他的鼠标和键盘......
If im right, then look at the reply at this link, it may be what you want...
如果我是对的，那么看看这个链接的回复，它可能是你想要的......
its in c++ but well not a big matter I guess...
它在 C++ 中，但我想这不是什么大问题......
