Oh, RAID disk device. Rootkits : Subverting the Windows Kernel book I would not point on this "book" as a serious technical book because it contains mostly untested and out-of-date code. This instance-specifc data can be attached to the device structure and referenced by the driver when you get an IRP to process." Message 10 of 13 04 Oct 1111:22 If this parameter is zero and CreateFile succeeds, the file or device cannot be shared and cannot be opened again until the handle to the file or device is closed."

Result: First Handle is valid, other handles in same process and in other processes are all INVALID_HANDLE_VALUE. This is the default behavior if no other flags are specified along with the SECURITY_SQOS_PRESENT flag.   hTemplateFile [in, optional] A valid handle to a template file with the GENERIC_READ access Thanks in advance, Tristan.=20 --- NTDEV is sponsored by OSR For our schedule of WDF, WDM, debugging and other seminars visit:=20 http://www.osr.com/seminars To unsubscribe, visit the List Server section of OSR

Applications use this attribute to mark files for backup or removal. How does Integrity Analysis work? To ensure that the metadata is flushed to disk, use the FlushFileBuffers function. Writefile Msdn Why does an instrumented application runs so slow?

The calling process must be attached to an inherited console or one allocated by the AllocConsole function. Readfile Msdn Result: + First app: Handle1: xxx, Handle2: yyy + Second app: Handle1: zzz, Handle2: xxx + Third app: Handle1: zzz, Handle3: xxx As you can see, CreateFile succeeds every time in Rebooting should serve the same purpose.

Createfile Example

I made a small test application, to verify behavior: //=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D static GUID GUID_MY_DEVINTERFACE =3D {...}; DWORD index =3D 0; HDEVINFO hdi= =3D SetupDiGetClassDevs(&GUID_MY_DEVINTERFACE, NULL, NULL, (DIGCF_PRESENT = | DIGCF_DEVICEINTERFACE)); Distributed License Management does not recognize the license Distributing VxDs Do I always have to instrument and run my application from the VB IDE? Createfile C++ I was looking for where NT searches known devices, such as "COM1", to see why it's failing. Createfile C# Instead, boundary checks are performed by the device driver.   Changer Device The IOCTL_CHANGER_* control codes for DeviceIoControl accept a handle to a changer device.

If the file is not a reparse point, then this flag is ignored. have a peek at these guys For a long time, I assumed almost everyone did, because the other interfaces are so dreadful for information exchange, but I have since been informed that I am mistaken... -- Tim I was able to use the handle that I got back and use DeviceIOControl nicely. I already have that. Generic_read

If the specified file does not exist, the function fails and the last-error code is set to ERROR_FILE_NOT_FOUND (2).

StringMeaning "\\.\A:"Opens floppy disk drive A. "\\.\C:"Opens the C: volume. "\\.\C:\"Opens the file system of the C: volume.   You can also open a volume by referring to its volume name. Thanks again. GetLastError returns ERROR_ACCESS_DENIED. File_append_data I need to call SetupDiRemoveDeviceInterface() to remove that interface.

The driver created a symbolic link in the \\DosDevices tree with that name. Speaking of that, if you have lots of web experience (because WE sure as hell don't), then we'd be more than happy for you to volunteer to help us fix any Cannot run CodeReview batch while results are displayed Cannot see local variables in the local window. this content Result: First Handle is valid, other handles in same process and in other processes are all INVALID_HANDLE_VALUE.

Note  To read or write to the last few sectors of the volume, you must call DeviceIoControl and specify FSCTL_ALLOW_EXTENDED_DASD_IO. If FILE_FLAG_OPEN_REPARSE_POINT is not specified: If an existing file is opened and it is a symbolic link, the handle returned is a handle to the target. Is there a way to exclude the Microsoft generated code from a CodeReview? This flag is for use by remote storage systems.

Such approach may work under some microkernel-based system, because two instances of a driver are two different processes under such a system. They use CreateFile with and without Symbolic Link. If you choose to participate, the online survey will be presented to you when you leave the Msdn Web site.Would you like to participate? status = IoCreateSymbolicLink(&dosUnicodeString, &ntUnicodeString); DRIVER_BAIL_ON_FAILURE(status); You then use the device name: WCHAR pDeviceName[40]; wcscpy_s(pDeviceName, 40, L"\\\\.\\"); wcscat_s(pDeviceName, 40, pDevice); *pDriver = CreateFileW(pDeviceName, GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, /// lpSecurityAttirbutes

QUESTION: Does FailSafe work with VB 6? He does not really seem to care, does he - according to him, " It made sense to allocate separate memory using separate drivers.", and that's it...
