[英]How to create a universal keyboard shortcut?
I have searched online for this, but can't find nothing at all. 我在网上搜索过这个,但根本找不到任何东西。 What I would like to do is to create a keyboard shortcut that I would be able to use in all applications.
我想要做的是创建一个键盘快捷方式,我将能够在所有应用程序中使用。 A universal keyboard shortcut, so that when I press, say Ctrl + Shift + X in any application, it would execute a piece of code I created in C#.
一个通用的键盘快捷键,所以当我按下时,在任何应用程序中说Ctrl + Shift + X ,它将执行我在C#中创建的一段代码。 For example, when I'm in Skype, I would select text and press Ctrl + Shift + X (or whatever other key combination), it would change the color of the text from black to blue.
例如,当我在Skype时,我会选择文本并按Ctrl + Shift + X (或任何其他组合键),它会将文本的颜色从黑色更改为蓝色。 That is just an example to try and explain what I want to do.
这只是尝试解释我想做什么的一个例子。 I'm thinking I would have to import a DLL and edit that (maybe user32.dll?) I'm just guessing.
我想我必须导入一个DLL并编辑它(也许是user32.dll?)我只是在猜测。 I have no clue how to do this, so any help will be greatly appreciated!
我不知道如何做到这一点,所以任何帮助将不胜感激!
Thanks a lot in advance :) 非常感谢提前:)

不清楚我想做什么/说什么? Please feel free to comment and I will get back to you right away.

Win32 has a RegisterHotKey function as part of the Win32 API. Win32具有RegisterHotKey函数作为Win32 API的一部分。 To use it in managed code (C#), you'd have to pInvoke it.
要在托管代码(C#)中使用它,您必须pInvoke它。 Here is an example:
这是一个例子:
public class WindowsShell
{
#region fields
public static int MOD_ALT = 0x1;
public static int MOD_CONTROL = 0x2;
public static int MOD_SHIFT = 0x4;
public static int MOD_WIN = 0x8;
public static int WM_HOTKEY = 0x312;
#endregion
[DllImport("user32.dll")]
private static extern bool RegisterHotKey(IntPtr hWnd, int id, int fsModifiers, int vlc);
[DllImport("user32.dll")]
private static extern bool UnregisterHotKey(IntPtr hWnd, int id);
private static int keyId;
public static void RegisterHotKey(Form f, Keys key)
{
int modifiers = 0;
if ((key & Keys.Alt) == Keys.Alt)
modifiers = modifiers | WindowsShell.MOD_ALT;
if ((key & Keys.Control) == Keys.Control)
modifiers = modifiers | WindowsShell.MOD_CONTROL;
if ((key & Keys.Shift) == Keys.Shift)
modifiers = modifiers | WindowsShell.MOD_SHIFT;
Keys k = key & ~Keys.Control & ~Keys.Shift & ~Keys.Alt;
keyId = f.GetHashCode(); // this should be a key unique ID, modify this if you want more than one hotkey
RegisterHotKey((IntPtr)f.Handle, keyId, (uint)modifiers, (uint)k);
}
private delegate void Func();
public static void UnregisterHotKey(Form f)
{
try
{
UnregisterHotKey(f.Handle, keyId); // modify this if you want more than one hotkey
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
}
public partial class Form1 : Form, IDisposable
{
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
Keys k = Keys.A | Keys.Control;
WindowsShell.RegisterHotKey(this, k);
}
// CF Note: The WndProc is not present in the Compact Framework (as of vers. 3.5)! please derive from the MessageWindow class in order to handle WM_HOTKEY
protected override void WndProc(ref Message m)
{
base.WndProc(ref m);
if (m.Msg == WindowsShell.WM_HOTKEY)
this.Visible = !this.Visible;
}
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
WindowsShell.UnregisterHotKey(this);
}
}
