我正在制作一款适用于游戏的音乐播放器, 我已经知道如何在正常的winform -wpf应用程序中处理键盘输入。
但是,它在游戏中不起作用
我正在使用这个钩子
Imports System.Runtime.InteropServices
Imports System.Windows.Forms
Public Class KeyboardHook

Private HHookID As IntPtr = IntPtr.Zero
Private Function KeyboardProc(ByVal nCode As Integer, ByVal wParam As IntPtr, ByVal lParam As IntPtr) As Integer
If (nCode = HC_ACTION) Then
Dim struct As KBDLLHOOKSTRUCT
Select Case wParam
Case WM_KEYDOWN, WM_SYSKEYDOWN
RaiseEvent KeyDown(CType(CType(Marshal.PtrToStructure(lParam, struct.GetType()), KBDLLHOOKSTRUCT).vkCode, Keys))
Case WM_KEYUP, WM_SYSKEYUP
RaiseEvent KeyUp(CType(CType(Marshal.PtrToStructure(lParam, struct.GetType()), KBDLLHOOKSTRUCT).vkCode, Keys))
End Select
End If
Return CallNextHookEx(IntPtr.Zero, nCode, wParam, lParam)
End Function
Public Sub New()
HHookID = SetWindowsHookEx(WH_KEYBOARD_LL, KBDLLHookProcDelegate, System.Runtime.InteropServices.Marshal.GetHINSTANCE(System.Reflection.Assembly.GetExecutingAssembly.GetModules()(0)).ToInt32, 0)
If HHookID = IntPtr.Zero Then
Throw New Exception("Could not set keyboard hook")
End If
End Sub
Protected Overrides Sub Finalize()
If Not HHookID = IntPtr.Zero Then
UnhookWindowsHookEx(HHookID)
End If
MyBase.Finalize()
End Sub
End Class

编辑:问题是钩子有效,但不能用于dx游戏
答案 0 :(得分:0)
好吧,经过几个小时的测试,我找到了解决方案 1 - 您可以使用任何类,但我更喜欢本机HotKeyManager类
2 - 您必须以管理员身份从OUTSIDE visual studio调试器
运行程序
