                return CallNextHookEx(hKeyboardHook, nCode, wParam, lParam);
        }
    }
}

這個類在VS2003中初始化沒一點問題
但在VS2005裡運行就出現問題了..
問題出在
hMouseHook = SetWindowsHookEx(
WH_MOUSE_LL,
MouseHookProcedure,
Marshal.GetHINSTANCE(
Assembly.GetExecutingAssembly().GetModules()[0]),
0);
if (hMouseHook == 0)
{
int errorCode = Marshal.GetLastWin32Error();
Stop(true, false, false);
throw new Win32Exception(errorCode);
}
errorCode返迴1,有時返迴1008的異常
