我在一个项目中为旧游戏做一些键重新绑定，在这些游戏中您没有选择要做什么键的选择。在示例中，我想按“ Num0”来模拟“ z”键。 我的问题如下： 我编写了一个GUI来设置要按下的键以及应该使用WindowsInputSimulatorPlus模拟的键。现在我不知道如何正确设置挂钩。 万一我用
return CallNextHookEx(hookID, nCode, wParam, lParam);
它将模拟我要模拟的键，而Windows将处理按下的键（我不想）。
改为使用return (IntPtr)1;时，它根本不会模拟任何东西。
要执行以下操作，我需要更改什么： 按“ Num0”->在Windows中不处理“ Num0”，而是模拟Windows的“ Z”？其他所有键均不受此影响，应照常进行处理。
在这里查看我的代码：
