    - [Printer Driver] Issue with OEMSendPage and KB934238 Dear all, I'm a printer driver designer and I have a problem with the unidriver. Indeed, apparently, Unidriver has been changed in the KB934238 fix. My driver was working fine before this, but now, the OEMSendPage is not even called in my OEMunidriver... Which results is wrong printout... Anyone has an idea on why I have such a behavior, and how to correct it? Regards... Ludo... Tag: What is the exact difference between a Task and a Process under NT?

    - How to read contents of DMA scattergather list within driver conte Hello - Can anybody tell me how to read the contents of a scatter/gather list created in a WDM driver? In this case, the scatter/gather list is created with GetScatterGatherList(), and later freed with PutScatterGatherList(). I would like to read the contents of this list as soon as possible after it has been filled in by the hardware, before the IO Manager returns the results to the calling application. When I try to read the contents of the scatter/gather list just before PutScatterGatherList() is called, I get a IRQL_NOT_LESS_THAN_OR_EQUAL bug check. When I try to read the contents of the list within the context of a worker thread later on (to avoid the the above bug check by executing at a lower IRQL), I get a memory access fault. Trying to read the the virtual address of the user buffer associated with the MDL of the IRP request causes a memory access fault because that address is not valid within the context of the worker thread. As yet, the only way I can read the results of the scatter/gather operation is from a user buffer in the calling client application. The device doing the DMA access is DIRECT_IO (not buffered). The target system is WindowsXP. Any pointers would be very much appreciated. Robert Cohn Tektronix, Inc.

    - Strange error possibly because of code in driver entry I had a previous thread about the way to make a corect message for IRP_MJ_READ, so if you read it u know that I am making a file system filter driver based on the sfilter exmaple from the WDK from Microsoft. For those who don't know sfilter, it attaches to all the volume devices, and processes the IRP's as pass throughs. The problem is that whenever I write some code in the driver entry, except the existent code, code like calling a function or something it has something to do with the code later on and I don't understand why. for example I have a function called NTSTATUS GetFileObjectFromPathEx( PDEVICE_OBJECT DeviceObject, PUNICODE_STRING Path, PFILE_OBJECT *FileObject, PHANDLE FileHandle, IN ACCESS_MASK DesiredAccess) which give u the file object for a file by a given path, by sending the request to a specific Device. the thing is that when I call this function in my IRP_MJ_WRITE dispatch routine the function works great, every time, I have no problem using it. well when I call the funtion in driver entry, just for testing I mean, the things change later on. In my IRP_MJ_WRITE I need to get the file name for the current file and compare it I use RtlCompareUnicodeString If I don't call GetFileObjectFromPathEx or other functions made by me in driverentry, the comparing goes smoothly, but if I call this function or any other function that calls some api like: IoCreateFileSpecifyDeviceObjectHint or ZwCreateKey or ZwQueryValueKey the code crashes in the RtlCompareUnicodeString If i comment the rtlcompareunicodestring in my dispatch routines and also call the functions in the driver entry everything goes smoothly. Why does this happen. How should I make my initializations. . . I close all the handles I open in the driverentry and dereference all objects if I reference any, so I have no memory leaks that could affect in the future. Please help, note that this is file system filter driver, and the device is of this type: FILE_DEVICE_DISK_FILE_SYSTEM. thank you Tag: What is the exact difference between a Task and a Process under NT?

    - Anyone successfully used DDK to compile user mode components with Hi! I have a few user mode components and I want them to be shown with XP visual styles. The drivers and the user mode components are usually build with the DDK in the same build process. To enable visual styles I followed the rules on http://msdn2.microsoft.com/en-us/library/ms649781.aspx but the UM components are still shown old fashion. If I ship a separate manifest file for the control panel applet then I have visual styles but this way doesn't work for shell extensions. I'm sure that the manifest file is embedded into my binary because I can see them with a hex editor. The manifest file is included like this: CONTROL_PANEL_RESOURCE_ID RT_MANIFEST "<name>.cpl.manifest" or ISOLATIONAWARE_MANIFEST_RESOURCE_ID RT_MANIFEST "<shellex>.dll.manifest" In both cases I've called InitCommonControls() and in the second case I've added ISOLATION_AWARE_ENABLED as C_DEFINES into my "source" file. Has anyone successfully used DDK to compile user mode components with XP visual styles and can give a hint? Thanks! -- h.wulff Tag: What is the exact difference between a Task and a Process under NT?

    - Wait problem in UVC filter driver Hi all, I am developing a class upper filter for webcam devices. It has to wait for a event in read stream completion routine. I used KsWaitForSingleObject() to wait and set time out is 0.1s. However, I found that the read stream completion routine function is called with DISPATCH_LEVEL in UVC device, and in PASSIVE_LEVEL in non- UVC device. This results BSOD when calling KsWaitForSingleObject() with UVC device. So my question is: how can I wait for a event in filter driver for UVC driver? What results the IRP level different?

    - Printing Driver - Devmode Hi, ich try to read out printing informations. i read out the informations with "documentproperties" and "getprinter" these are the standard informations, right ? what about with the specific informations ? (spec. driver informations) i see in the devmode struct the field "dmFields" and "dmDriverExtra". This means that a second struct follows the devmode struct, right ? is it possible to read out these informations ? and how ? Or do i need something about the driver interface ? I want to read out spec. driver informations like - document name - printer name - count of copies .. and spec. things: - quality - layout - finishing .. greetings Martin Tag: What is the exact difference between a Task and a Process under NT?

    - Running NDISTest on Vista with an NDIS IM Driver Has anyone tried to do this? What version of NDISTest did you use and what was your experience like? I tried using the version that comes with WLK/DTM on PassThru (NDIS IM sample) and got a BSOD while running 1c_wmicoverage.

    - WDK 6000 compilation issue I developed a kernel driver and a user mode dll. I use two sources file and dirs file to compile both driver and user mode dll in WDK environment itself. I have no problems till WDK 5112. When I used WDK 6000, I cannot use user mode dll anymore. Applications when trying to load user mode dll give exception "The procedure entry point _except_handler4_common couldnot be located in the dynamic link library msvcrtd.dll". I compile both dll and driver in WDK console window in Windows XP debug build. Free build works fine. I think my user mode dll is getting linked with some version of msvcrtd.dll that is not compaitible. Same problem even with windows 2000 build. What is the correct way to solve this ? Should I include some library path? 2) How will I know which library path is used in WDK console? How will I know which library was used to link with my dll.

So can I directly call WmiTraceMessage (where I just need to give a buffer pointer and length) instead of going through DoTraceMessage (which is a macro around the former)? Will it have any effect on the tracelog.exe/tracefmt.exe applications (in terms of log formatting) that I run on user space? Or is there any other way of logging binary data using Tracing?

    - Regarding SDIO CID Hi, I have to read in an application the CID of the SDIO card. The SD card is connected to the desktop through USB. Is there any way to do this in application? (CE supports a DeviceIoControl code for this if I remember) Or, if there's no device IO control code supported, can it be done in a driver? (In XP, I think we can open the SDBus interface and post a SDB request packet to send the command to query the CID, if I am correct. But in 2000, SDBus interface itself is not supported.)

    - Problem with NdisMEthIndicateReceive - not receiving data Hi, I am developing network adapter to transfer TCP/UDP packets from the ip layer (through the ndis driver) to the com port to other remote PC and vice- versa under the WM5 using the VS2005 and Windows Mobile 5.0 Pocket PC SDK. Before sending/receiving data, I set the ARP entries of the remote PC statically. The problem is when the remote PC is sending data and the PDA receive it and pass it to the NDIS driver through the function NdisMEthIndicateReceive and the function NdisMEthIndicateReceiveComplete, the data didn't pass to higher protocols above the ip layer and the applications whic uses the tcp/udp which wait for the data, didn't receive any of it. I have a little application which displays all the adapter installed on the PDA and the binding to the relevant Protocols and i notice there is no problem of binding, since the adapter is bind to the TCPIP, TCPIP6 and NDISUIO protocols. I checked several posts of that problem and notice about the OID_GEN_CURRENT_PACKET_FILTER I checked that value and it gave me the value 11 (0x0000000B), my tries to change that value didn't suceed, so maybe that the problem, or maybe not since i can see that the adapter is binding to the TCPIP protocol. Anyway, I would _really_ appreciate if some can help me solving that problem. Best regards, ligal Tag: What is the exact difference between a Task and a Process under NT? Tag: 96948

    - WinXP USB BULK mode High speed We have a scenario as follows using BULK mode: - High speed USB device that provides MPEG2 TS. Device has 2K FIFO. - Stream rate is approx. 32 Mbit/s, so we see an IN token in about 7000 out of the 8000 microframes per second. - Our USB client driver is queuing up 8 requests, then requeueing 1 on Bulk complete, to make sure there is always a request ready for Host Controller. - The driver is requesting 564 bytes( 3 * 188) at a time. Problem: - Some microframes come back to back from Host controller without an IN token and we lose MPEG2 data from the device, since the device overflows its FIFO. IS there anything we can do in our client driver to increase throughput? Thanks decoder Tag: What is the exact difference between a Task and a Process under NT? Tag: 96926

    - Save all the dump files Hi, We are getting a series of system crash sometimes and I donâ??t want to lose any crash dump since it represents a bug. So we set dump â??overwriteâ?? flag to 0 in registry to save the first dump. When the system comes up, with the help of a small application (starting automatically), rename the .dmp file with a timestamp. This is working fine and saving all the subsequent dump files (max of 7 dumps by considering the memory). But sometimes the driver is getting crashed while loading and that is before savedump.exe completes itâ??s copying from pagefile to dump file. So the previous crash dump is lost. Please let me know any graceful way of delay the driver loading if the savedump process is running or any other idea in this scenario to save all dump files?

    - Signability Warning: Missing HWID I am trying for the first time to generate a Catalog (.cat) file for a driver package based on the MSVAD sample. I am using Signability v2.19 for that (on Windows XP). The test is passed (with some warnings) and the Catalog file is successfully generated. However, I am puzzled by the following warning: 22.9.3 WARN: Windows XP: Missing HWID (cannot have just compatid) in line "%msvad.devicedesc%=msvad,,*msvad_ in section [msvaddevicesection] of \msvad.inf Now... I know that the HIWD is missing. But that's what Microsoft placed there - probably for a purpose. So my questions are: 1. Do I really have to have an HWID (aka DeviceId in Oney's book) in the device description statement in the .inf file for the cat file to be signed? 2. Will the driver load/work if I put there an HWID?

    - Windows CE 5.0 Stream Interface Driver I have written/modified a CE driver to access a quad serial Uart (specifically an Exar 16C8541). What appears to be working is the ability to transmit and receive with the driver on a given serial or COM port when an application requests to do so. What does not appear to be working is the ability to open more than one serial or COM port at a time. Example: If COM1 is open COM2 fails to open. If COM1 is closed then COM2 will open. Any clues as to what I may be doing wrong? Attached is debug output for CE initialization of the driver (in this case only COM1 and COM2). I have placed debug info for all functions in the driver yet when I try to open the second COM2 port simultaneously with COM1 I see no driver activity whatsoever. Additional Info: There is only one physical interrupt for all the Exar COM ports. The kernel is sending debug data through one of three serial ports built into the processor (Cirrus EP9315) - Platform builder has the driver removed for the remaining 2 built in Cirrus serial ports so they do not conflict with the COM naming convention used for the Exar part (Only the Exar seral driver is in effect in the registry). Any information as to why only one port opens would be greatly appreciated.

    - Problem with matching kind of NDIS driver. Hi, I have to write the driver, which will be monitoring all network activity (all protocols) and get PID (identity of the process) which is directly responsible for that. Unfortunately, I don't know which kind of NDIS drivers will be best for that. I think, the best will be NDIS Intermediate Driver, but I can be mistaken. Please help me with matching kind of driver. -- With regards thanks, Witek Tag: What is the exact difference between a Task and a Process under NT? Tag: 96892

    - DPInst and virtual drivers (e.g. MSVAD) I am trying to understand from reading the DPInst WDK documentation to which category a virtual device driver would fall: a "device that is configured in the system" or a "nonpresent device"? The documentation reads: "DPInst checks whether the hardware identifiers or compatible identifiers in the INF file match a device that is configured in the system or match a nonpresent device." Since in a virtual device driver there is no hardware involved (i.e. no "device that is configured in the system"?), it is tempting to think that DPInst would be dealing with a "nonpresent device", right? But when I install a virtual device driver (e.g. MSVAD) manually, using Control Panel's Add Hardware, I am first prompted by a question "Have you already connected this hardware to your computuer?" - to which I must answer "Yes, I have already connected the hardware" or else the driver will not be installed... So, how is a virtual device driver treated from the standpoint of DPInst? Thanks, Don Tag: What is the exact difference between a Task and a Process under NT? Tag: 96889

    - Strategies for High-bandwidth Isochronous USB with AVstream minidriver Hi All, I'm trying to implement a video capture pin that uses the Process dispatch to queue frame buffers. It then uses a separate thread to take a frame from the queue and initiate a frame read into it. The read completion routine does a KsPinAttemptProcessing call to keep the leading edge buffers coming. The frame buffer queue is 5 deep. The pin runs for about 20 frames before the calls to Process start to fall behind and there are errors on some of the iso packets. When it reaches this "stable" state, Process is called at approx 17ms intervals. The iso read is for 14x24K for a full frame so it should occur at 14ms intervals. Should this approach work? What can be changed to make the Process calls come in at a 14ms rate? Thanks for any suggestions, -Stan Tag: What is the exact difference between a Task and a Process under NT? Tag: 96887

    - IOCTL_DISK_GET_PARTITION_INFO_EX on Dynamic MBR data Hi, At present time our customers are widely using the GUID Partition Table (GPT). GPT provides a more flexible mechanism for partitioning disks than the older Master Boot Record (MBR) partitioning scheme that has been common to PCs. The problem is that the our client fails calling the DeviceIoControl() function with the ioctl IOCTL_DISK_GET_PARTITION_INFO for a GPT partition. It is obvious that the extended ioctl IOCTL_DISK_GET_PARTITION_INFO_EX should be used here. According to MSDN (http://msdn2.microsoft.com/en-us/library/aa365180.aspx) the IOCTL_DISK_GET_PARTITION_INFO_EX control code is supported on basic disks. It is only supported on dynamic disksthat are boot or system disks, or have retained entries in the partition table. The DiskPart.exe command RETAIN can be used to do this for other dynamic simple partitions.The disk support can be summarized as follows. Disk type IOCTL_DISK_GET_PARTITION_INFO IOCTL_DISK_GET_PARTITION_INFO_EX Basic MBR Yes Yes Basic GPT No Yes Dynamic MBR boot/system Yes Yes Dynamic MBR data Yes No Dynamic GPT boot/system No Yes Dynamic GPT data No No So, I am concerned about "dynamic MBR data" which is supported by IOCTL_DISK_GET_PARTITION_INFO but is NOT supported by its _EX version. Any ideas? Thanks, Andrei Nehay Tivoli Storage Manager Client Development nehaya@us.ibm.com Tag: What is the exact difference between a Task and a Process under NT? Tag: 96882

Hi, experts,

I have a clear understanding of the difference between a process and a
thread. However, I can't find any difference between a Task and a
Process.

In addtion I know a Job contains many processes. Whether or not a Job
is just a synonym of a Task?

Who can give me an explaination? Any help will be highly appreciated.
Many thanks in advance.

Task is synonomous with Process in Win32. (There are other contexts where
task measn something completely diffrent but those are not likely
relevent[ e.g task scheduler; task = something to do at a specific time])
