模拟在另一个应用程序按键和keyrelease？ [英] Simulating a keypress AND keyrelease in another application?

问题描述

我需要与外部应用程序的运行交互，发送特定的按键和放大器;版本。我试图使用SendKeys类，但它确实只是工作的一半，作为按键正接受立即keyrelease到外部应用程序发送的。

I need to interact with an external application running, and send specific keypresses & releases. I've tried to use the SendKeys class, but it does only half of the job, as the keypress is being sent with an immediate keyrelease to the external applications.

我需要能够以模拟键保持向下，用于外部应用程序。现在我尝试使用SendMessage函数的事情，但现在它不会在所有的工作:(我甚至不出错。

I need to be able to simulate a "key hold down" for the external app. I'm now trying to use the SendMessage thing, but for now it won't work at all :( and I don't even get errors.

推荐答案

好吧，案件告破。我实际安装VC ++尝试核心keybd_event（）函数，之后它的工作，我能够使用它的明智在C＃。

Ok, case solved. I actually installed VC++ to try the core keybd_event() function, and after it worked I was able to use it wisely in C#.

下面的代码，并令人惊讶的是非常简单的，您需要添加此使用您的代码能够导入dll的：使用System.Runtime.InteropServices;

Here's the code, and surprisingly it's very simple. You'll need to add this using to your code to be able to import dll's: using System.Runtime.InteropServices;

这代码将按住1键3秒，然后将释放1秒钟，重复这个过程。

This code will press and hold the '1' button for 3 secs, and then will release for 1 second and repeat the process.

（代码高亮弄乱：/，自复制'命名空间......到最后括号'}'）

(the code highlight got messed up :/, copy from 'namespace ...' to the last bracket '}')

namespace ConsoleApplication1 
{
class Program 
{ 
	[DllImport("user32.dll")] 
	static extern void keybd_event(byte bVk, byte bScan, uint dwFlags,UIntPtr dwExtraInfo);

	static void Main(string[] args)
	{            
		while (true)
		{
			keybd_event((byte)0x31, (byte)0x02, 0, UIntPtr.Zero);
			Thread.Sleep(3000);

			keybd_event((byte)0x31, (byte)0x82, (uint)0x2, UIntPtr.Zero);
			Thread.Sleep(1000);
		}
	}
}

}
