关于WinIO.DLL的键盘输入模拟
最近在找键盘模拟的方式，最后在网上找到了一个WinIO.DLL的IO键盘模拟按键的方式。但是居然那个方法是有问题的。我造了全局的hook监视键盘信息，发现它只是有keyDown和keyPress的消息，keyUp的信息是up了一个zoom的键。
搞了2天终于找到了正确的方式，以下是代码（使用需要winIo.dll,winIo.vxd,winIo.sys）：
public class WinIOLab 
{ 
private const int KBC_KEY_CMD = 0x64; private const int KBC_KEY_DATA = 0x60; [DllImport("winio.dll")] private static extern bool InitializeWinIo(); [DllImport("winio.dll")] private static extern bool GetPortVal(IntPtr wPortAddr, out int pdwPortVal, byte bSize); [DllImport("winio.dll")] private static extern bool SetPortVal(uint wPortAddr, IntPtr dwPortVal, byte bSize); [DllImport("winio.dll")] private static extern byte MapPhysToLin(byte pbPhysAddr, uint dwPhysSize, IntPtr PhysicalMemoryHandle); [DllImport("winio.dll")] private static extern bool UnmapPhysicalMemory(IntPtr PhysicalMemoryHandle, byte pbLinAddr); [DllImport("winio.dll")] private static extern bool GetPhysLong(IntPtr pbPhysAddr, byte pdwPhysVal); [DllImport("winio.dll")] private static extern bool SetPhysLong(IntPtr pbPhysAddr, byte dwPhysVal); [DllImport("winio.dll")] private static extern void ShutdownWinIo(); [DllImport("user32.dll")] private static extern int MapVirtualKey(uint Ucode, uint uMapType); private WinIOLab() 
{ IsInitialize = true; 
} public static void Initialize() { if (InitializeWinIo()) { KBCWait4IBE(); IsInitialize = true; } } public static void Shutdown() { if (IsInitialize) ShutdownWinIo(); IsInitialize = false; } private static bool IsInitialize { get; set; } ///等待键盘缓冲区为空 private static void KBCWait4IBE() { int dwVal = 0; do { bool flag = GetPortVal((IntPtr)0x64, out dwVal, 1); } while ((dwVal & 0x2) > 0); } /// 模拟键盘标按下 public static void KeyDown(Keys vKeyCoad) { if (!IsInitialize) return; int btScancode = 0; btScancode = MapVirtualKey((uint)vKeyCoad, 0); KBCWait4IBE(); SetPortVal(KBC_KEY_CMD, (IntPtr)0xD2, 1); KBCWait4IBE(); SetPortVal(KBC_KEY_DATA, (IntPtr)0x60, 1); KBCWait4IBE(); SetPortVal(KBC_KEY_CMD, (IntPtr)0xD2, 1); KBCWait4IBE(); SetPortVal(KBC_KEY_DATA, (IntPtr)btScancode, 1); } /// 模拟键盘弹出 public static void KeyUp(Keys vKeyCoad) { if (!IsInitialize) return; int btScancode = 0; btScancode = MapVirtualKey((uint)vKeyCoad, 0); KBCWait4IBE(); SetPortVal(KBC_KEY_CMD, (IntPtr)0xD2, 1); KBCWait4IBE(); SetPortVal(KBC_KEY_DATA, (IntPtr)0x60, 1); KBCWait4IBE(); SetPortVal(KBC_KEY_CMD, (IntPtr)0xD2, 1); KBCWait4IBE(); SetPortVal(KBC_KEY_DATA, (IntPtr)(btScancode | 0x80), 1); } 
}
keyDown和keyUp的信息都是用0x60，而keyUp则是在Key加上了 or 0x80 而已。
但是使用winIO.dll的办法在Win7 64x 上用不了的，根本注册不了驱动，不知有没有人研究得出解决办法。有的话请联系我：Anima.My@Gmail.com，谢谢。
