模拟X秒一个按键 [英] Simulate a keypress for X seconds

问题描述

下面是我的代码，我用它来模拟在一定的工艺制表按键：

Here is my code that I use to simulate a tab-keypress in a certain process:

[DllImport("user32.dll")]
static extern bool PostMessage(IntPtr hWnd, UInt32 Msg, int wParam, int lParam);

public Form1()
{
    PostMessage(MemoryHandler.GetMainWindowHandle(), 
               (int)KeyCodes.WMessages.WM_KEYDOWN, 
               (int)KeyCodes.VKeys.VK_TAB, 0);

    InitializeComponent();
}

有没有什么办法，使其塑机（例如钥匙将其扩展）1秒，而不是只攻呢？

Is there any way to extend it so that it presses the key for (example) 1 second, instead of just tapping it?

请注意，我不感兴趣，在 Thread.sleep代码（）解决方案，阻止UI线程。

Please note that I'm not interested in a Thread.Sleep() solution that blocks the UI thread.

推荐答案

在一个按键，当你按住重复是的内置功能到键盘控制器。该内置于键盘本身的微处理器。该 8042微控制器是传统的选择，键盘设备驱动程序仍然带有它的名字。

The repeating of a keystroke when you hold it down is a feature that's built into the keyboard controller. A microprocessor that's built into the keyboard itself. The 8042 microcontroller was the traditional choice, the keyboard device driver still carries its name.

所以，不，这不是由Windows和PostMessage的（）所做的是不会为你做它。不完全是一个问题，你可以简单地用一个定时器效仿。

So, no, this is not done by Windows and PostMessage() is not going to do it for you. Not exactly a problem, you can simply emulate it with a Timer.
