Global Hooks(非活动程序) [英] Global Hooks (non-active program)

问题描述

我正在创建一个程序，该程序允许您粘贴文本，但是看起来就像您在粘贴时键入文本一样，Paste Typer.

我想使用 Ctrl + b 取消粘贴，但是我在使用热键时遇到问题.

我认为我需要使用一个 WH_KEYBOARD_LL 钩子并包含该user32文件，但添加该文件和命名空间时通常会出错.

我与此最接近: http://thedarkjoker94.cer33.com/?p=111-但即使我使用了 KeyData ，它似乎也无法与 Ctrl ， alt 和其他修饰符一起使用.>

我需要一种使热键即使在该程序不是活动窗口时也可以使用的方法.这是Microsoft Visual C#2010中的Windows窗体应用程序.

有很多StackOverlow主题，但它们过时，而且不够完整，无法让我正常运行.

解决方案

您是否在谈论 HookManager ?

我这样成功地使用它:

  HookManager.KeyDown + =新的KeyEventHandler(HookManager_KeyDown); 

和

  void HookManager_KeyDown(对象发送者，KeyEventArgs e){if(Keyboard.IsKeyDown(Keys.LWin))//是否按下了Windows左键并...开关(e.KeyCode){案例Keys.O://...e.Handled = true;休息;案例Keys.H://...e.Handled = true;休息;}} 

我创建了Keyboard类，这里是代码:

 //二手:http://www.pinvoke.net/default.aspx/user32.getasynckeystate使用System.Runtime.InteropServices;使用System.Windows.Forms;命名空间Win32.Devices{公共课键盘{[DllImport("user32.dll")]静态外部超短GetAsyncKeyState(Keys vKey);公共静态布尔IsKeyDown(Keys key){返回0！=(GetAsyncKeyState(key)& 0x8000);}}} 

I am creating a program that allows you to paste text but it will look like you are typing it as it pastes, Paste Typer.

I am wanting to use Ctrl + b to set off the pasting, but I am having issues with hotkeys.

I think what I need is to use a WH_KEYBOARD_LL hook and include that user32 file but I usually get errors when I add it and the namespace.

I have come closest with this: http://thedarkjoker94.cer33.com/?p=111 - but it doesn't seem to work with Ctrl, alt and other modifiers, even when I used KeyData.

I need a way to make a hotkey that will work even when the program is not the active window. This is a windows forms application in Microsoft Visual C# 2010.

There a rea lot of StackOverlow topics but they are dated and are not complete enough for me to get something running.

解决方案

Are you talking about the HookManager?

I use it successfully like this:

HookManager.KeyDown += new KeyEventHandler(HookManager_KeyDown);

and

void HookManager_KeyDown(object sender, KeyEventArgs e)
{
    if (Keyboard.IsKeyDown(Keys.LWin)) // Is the Left-Windows Key down and ...
        switch (e.KeyCode)
        {
            case Keys.O: 
                // ...
                e.Handled = true;
                break;
            case Keys.H: 
                // ...
                e.Handled = true;
                break;
        }
}

I created the Keyboard class here is the code:

// Used: http://www.pinvoke.net/default.aspx/user32.getasynckeystate
using System.Runtime.InteropServices;
using System.Windows.Forms;

namespace Win32.Devices
{
    public class Keyboard
    {
        [DllImport("user32.dll")]
        static extern ushort GetAsyncKeyState(Keys vKey);

        public static bool IsKeyDown(Keys key)
        {
            return 0 != (GetAsyncKeyState(key) & 0x8000);
        }
    }
}
