新手请教,简单问题

windows98下的VXD编程:
按书上教的,鼠标中断记数累加
Mouse.vxd
//Mouse.h - include file for VxD Mouse

#include <vtoolscp.h>

#define DEVICE_CLASS MouseDevice
#define MOUSE_DeviceID UNDEFINED_DEVICE_ID
#define MOUSE_Init_Order UNDEFINED_INIT_ORDER
#define MOUSE_Major 1
#define MOUSE_Minor 0

#define MY_IRQ 12

class MyHwInt:public VSharedHardwareInt
{
public:
MyHwInt():VSharedHardwareInt(MY_IRQ, 0, 0, 0){}
virtual BOOL OnSharedHardwareInt(VMHANDLE);
};


class MouseDevice:public VDevice
{
public:
virtual DWORD OnW32DeviceIoControl(PIOCTLPARAMS pDIOCParam);
};





//Mouse.cpp - main module for VxD Mouse

#define DEVICE_MAIN
#include \"mouse.h\"
Declare_Virtual_Device(MOUSE)
#undef DEVICE_MAIN


#include \"apcx.h\"

PVOID  CallBackApc = 0;

THREADHANDLE TheThread = 0;
MyHwInt * pMyIRQ;
int x = 0;

BOOL MyHwInt::OnSharedHardwareInt(VMHANDLE hVM)
{
x++;
VWIN32_QueueUserApc(CallBackApc, (DWORD)&x, TheThread);
sendPhysicalEOI();
return FALSE;
}

DWORD MouseDevice::OnW32DeviceIoControl(PIOCTLPARAMS pDIOCParams)
{
switch (pDIOCParams->dioc_IOCtlCode)
{
case DIOC_OPEN:
pMyIRQ = new MyHwInt();
if (!pMyIRQ || !pMyIRQ->hook())
return -1;
return 0;

case DIOC_CLOSEHANDLE:
if (pMyIRQ)
delete pMyIRQ;
return 0;

case ADDRPASS:
CallBackApc = pDIOCParams->dioc_InBuf;
TheThread = Get_Cur_Thread_Handle();
return 0;
default:
return -1;

}


}

#MOUSE.mak - make fiel for VXD mouse

DEVICENAME = MOUSE
DYNAMIC = 1
FRAMEWORK = CPP
DEBUG = 1
OBJECTS = mouse.obj

!include $(VTOOLSD)\\include\\vtoolsd.mak
!include $(VTOOLSD)\\include\\vxdtarg.mak


mouse.obj: mouse.cpp mouse.h



然后应用程序是:
#include <stdio.h>
#include <windows.h>
#include <winioctl.h>
#include \"apcx.h\"


DWORD WINAPI CallBackAPC(PVOID param)
{
printf(\"%d\\n\", *(int*)param);
return 0;
}

void main()
{
HANDLE hDevice;
hDevice = CreateFile(\"\\\\\\\\.\\\\Mouse.vxd\", 0, 0, 0, CREATE_NEW,
FILE_FLAG_DELETE_ON_CLOSE, 0);
if (hDevice = INVALID_HANDLE_VALUE)
{
fprintf(stderr, \"Cannot load VxD, error=%08ld\\n\", GetLastError());
exit(1);
}

if (!DeviceIoControl(hDevice, ADDRPASS, CallBackAPC, 0, 0, 0, 0, 0))
{
fprintf(stderr, \"Failed to pass address\\n\");
exit(1);
}

printf(\"press Ctrl-C to exit...\\n\");
while(TRUE)
SleepEx(INFINITE, TRUE);
CloseHandle(hDevice);
}


运行总是说不能加载vxd,错误00000002
我的机器的鼠标中断是12
高手指教呀,小弟初学,谢谢

2代表找不到你的vxd文件

在哪儿放着

多看看msdn :D

可是明明就放在当前目录中呀,而且书上说2不一定就是指找不到vxd,有时不能加载也是2,而且我换成了静态的试了一下,vxdviewer中可以看到已经加载了,但应用程序还是说cannot load 00000002.....

放到系统目录下去
c:\\windows\\sysytem
 :D

放了是过了，不行的 :(
另外,我mouse.h和mouse.mak都不改
但是mouse.cpp中菜用win32事件编程,也就是用VWIN32_PulseWin32Event和OpenVxDHandle等唤醒应用程序第二个线程,就一切ok了,是不是98下的APC编程有什么特别的地方?

这我不态清楚，但这个和createfile有什么关系

就是说为什么采用APC方式时不行
而采用windows时间编程时就可以
