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):
{
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。
