我想知道 &H 十六进制代码代表什么键盘键？

例如，我发现 &H1 是 ALT 键，&H2 是 CONTROL 键，&H3 是同时按住 ALT 和 CONTROL 键。 &H10 是 Shift 键，它出现了。我这样问是因为我需要找出我正在设计的程序需要注册热键。用户可以选择隐藏它，我想确保他们可以通过按热键再次显示它，但我需要弄清楚十六进制键是什么才能使用我找到的代码。

这是我找到的代码的一部分：

Public Const MOD_ALT As Integer = &H1 'Alt key
Public Const WM_HOTKEY As Integer = &H312

<DllImport("User32.dll")> _
Public Shared Function RegisterHotKey(ByVal hwnd As IntPtr, _
                    ByVal id As Integer, ByVal fsModifiers As Integer, _
                    ByVal vk As Integer) As Integer
End Function

<DllImport("User32.dll")> _
Public Shared Function UnregisterHotKey(ByVal hwnd As IntPtr, _
                    ByVal id As Integer) As Integer
End Function

Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
    If m.Msg = WM_HOTKEY Then
        Dim id As IntPtr = m.WParam
        Select Case (id.ToString)
            Case "100"
                MessageBox.Show("You pressed ALT+D key combination")
            Case "200"
                MessageBox.Show("You pressed ALT+C key combination")
        End Select
    End If
    MyBase.WndProc(m)
End Sub

这会在加载表单时注册热键：

RegisterHotKey(Me.Handle, 100, &H3, Keys.D)
RegisterHotKey(Me.Handle, 200, Keys.Alt, Keys.C)

This 是我在 MSDN 论坛上查看的主题 - 我从特色答案中复制了代码。

我已经在 Google 上进行了彻底的搜索，并且在 StackOverflow 上进行了搜索，但我找不到任何东西。

某处是否有十六进制代码列表，或说明或其他内容？

谢谢！

EDIT: I found an article that lists exactly what I needed: http://msdn.microsoft.com/en-us/library/ms646309(v=vs.85).aspx

Thanks for your help!

Original:

I'm wondering what keyboard keys are represented by the &H hex codes?

For example, I've found that &H1 is the ALT key, &H2 is the CONTROL key, and &H3 is both the ALT and CONTROL keys together. &H10 is the Shift key, it appears. I'm asking because I need to find out for a program I'm designing that needs to register a hotkey. The user has the option to hide it, and I want to make sure that they can show it again by pressing a hotkey, but I need to figure out what the hex keys are to use the code that I found.

Here's part of the code I found:

Public Const MOD_ALT As Integer = &H1 'Alt key
Public Const WM_HOTKEY As Integer = &H312

<DllImport("User32.dll")> _
Public Shared Function RegisterHotKey(ByVal hwnd As IntPtr, _
                    ByVal id As Integer, ByVal fsModifiers As Integer, _
                    ByVal vk As Integer) As Integer
End Function

<DllImport("User32.dll")> _
Public Shared Function UnregisterHotKey(ByVal hwnd As IntPtr, _
                    ByVal id As Integer) As Integer
End Function

Protected Overrides Sub WndProc(ByRef m As System.Windows.Forms.Message)
    If m.Msg = WM_HOTKEY Then
        Dim id As IntPtr = m.WParam
        Select Case (id.ToString)
            Case "100"
                MessageBox.Show("You pressed ALT+D key combination")
            Case "200"
                MessageBox.Show("You pressed ALT+C key combination")
        End Select
    End If
    MyBase.WndProc(m)
End Sub

And this registers the hotkeys when the form loads:

RegisterHotKey(Me.Handle, 100, &H3, Keys.D)
RegisterHotKey(Me.Handle, 200, Keys.Alt, Keys.C)

This is the thread I was looking at on the MSDN forums -- I copied the code from the featured answer.

I've done a thorough Google search and I've searched here on StackOverflow, and I can't find anything.

Is there maybe a list of the hex codes somewhere, or instructions or something?

Thanks!

在您链接的 MSDN 线程中，有一个指向虚拟按键代码。
此外，请检查系统。 Windows.Forms.Keys 枚举。

请注意， RegisterHotKey 方法采用以下参数：hWnd、id、fsModifiers 和 vk。 VK 是放置 VirtualKey 代码的地方。关于 fsModifiers：

必须按下的键
与指定的键的组合
uVirtKey 参数以便
生成 WM_HOTKEY 消息。这
fsModifiers 参数可以是
以下值的组合：
MOD_ALT（0x0001），MOD_CONTROL
(0x0002), MOD_NOREPEAT (0x4000),
MOD_SHIFT（0x0004），MOD_WIN（0x0008）。
