驱动程序通知应用程序，急急急急

ZXGHEHE 2009-05-05 08:40:46

我想驱动在特定的情况下通知应用程序做一些操作,,看了一些牛人的文章,,有了个思路::::在应用中创建事件，然后通过ioctl传给驱动，驱动中ObReferenceObjectByHandle来引用该事件对象。这样应用和驱动中都可以检查和修改事件状态。
应用程序代码
int APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{

HANDLE hMutex;
BOOL bResult;
HANDLE hThread1;
HANDLE hDevice;
DWORD dwBytesReturned;
HANDLE g_Event = NULL ;

MSG msg;

hMutex = CreateMutex(NULL, TRUE, (LPCTSTR)"InpelRButton");
if (ERROR_ALREADY_EXISTS == GetLastError())
{
return 1;
}

g_Event = CreateEvent(NULL, FALSE, FALSE,NULL);
hThread1=CreateThread(NULL,0,Fun1Proc, g_Event,0,NULL) ;

hDevice = CreateFile( m_pszDevice, GENERIC_READ | GENERIC_WRITE,
0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
_ASSERTE( INVALID_HANDLE_VALUE != hDevice);

if (hDevice == INVALID_HANDLE_VALUE)
{
return FALSE;
}

bResult = DeviceIoControl(
hDevice,
IOCTL_SET_NOTIFICATION_EVENT,
(PVOID)&g_Event,//句柄
//(LPVOID)g_Event,
sizeof(g_Event),//
NULL,
0,
&dwBytesReturned,
NULL);
_ASSERT(bResult);

if (hDevice)
{
CloseHandle(hDevice);

}

while (GetMessage(&msg, (HWND) NULL, 0, 0) != 0 && GetMessage(&msg, (HWND) NULL, 0, 0) != -1)
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}

线呈函数
DWORD WINAPI Fun1Proc(HANDLE g_Event )
{
HANDLE g_Event2 = g_Event ;

while(1)
{

WaitForSingleObject(g_Event2, INFINITE);

mouse_event (MOUSEEVENTF_LEFTUP , 50, 0, 50, 0);
mouse_event (MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0);
mouse_event (MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0);
Sleep(5000);
// mouse_event (MOUSEEVENTF_LEFTDOWN , 0, 0, 0, 0);
// mouse_event (MOUSEEVENTF_LEFTUP , 0, 0, 0, 0);
mouse_event (MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0);
mouse_event (MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0);
Sleep(5000);
// mouse_event (MOUSEEVENTF_LEFTDOWN , 0, 0, 0, 0);
// mouse_event (MOUSEEVENTF_LEFTUP , 0, 0, 0, 0);
mouse_event (MOUSEEVENTF_RIGHTDOWN, 0, 0, 0, 0);
mouse_event (MOUSEEVENTF_RIGHTUP, 0, 0, 0, 0);
// ResetEvent(g_Event);
}
return 0;

}

驱动函数
case IOCTL_SET_NOTIFICATION_EVENT:
hEvent = *(PHANDLE)Irp->AssociatedIrp.SystemBuffer;
if((nInputLength==0)||(nInputLength <sizeof(hEvent)))
{
status = STATUS_INVALID_BUFFER_SIZE;
break;
}

status = ObReferenceObjectByHandle(hEvent,
EVENT_MODIFY_STATE,
*ExEventObjectType,
Irp->RequestorMode,
//KernelMode,
(PVOID*) &Requestevent,
NULL);

if (!NT_SUCCESS(status))
{
Print(deviceExtension, DBG_ALWAYS, ("status222 = %d\n",
status));
}
else
{
Print(deviceExtension, DBG_ALWAYS, ("status333 = %d\n",
status));
}
KeSetEvent(&Requestevent,0, FALSE);
break;

Irp->IoStatus.Status = status;
IoCompleteRequest(Irp, IO_NO_INCREMENT);

return status;

现在的问题是,,实现不了我的功能不出现什么错误就是实现不了同步,,,还请高人指点今天第一次用这个网站现在没有分可以给不过以后一定补上希望高手指点啊
