    - Desktop capture driver Hello, How I should write a desktop capture driver? Basically this driver should work as a virtual video driver. Is anybody point out me from where I should start with? Note: I have already written a virtual video driver which is a user mode DLL. Is this the way I should follow for the desktop capture driver? Thank you, Sreeram Tag: How to block an irp Tag: 54916

    - Ndiswan and tapi with multiple adapters problem - windows 98 I have a intermediate driver binded to ndiswan and uses tapi calls to establish connections. the driver works fine with a single adapter for windows 98. It also works fine with windows 2000 and NT for multiple adapters. Problem is for the driver on windows 98 for more than one adapter. The driver is installed on all adapters (binding is fine). The driver works properly for one of the adapters in the system, and for others it tries to send data to the adapter which is working fine. eg If a system has adapter a1, and a2 and driver works fine for a1. When the connection is tried to establish using adapter a2 , it tries to send data to a1. can anybody guess what could be the problem --Thank you in advance Jyotsna Tag: How to block an irp Tag: 54915

    - Detect USB types - help! Hi there, I need some help here. Basically my PC has 6 USB ports (USB1, USB2, USB3, USB4, USB5 and USB6). Just say I have 3 USB devices (Reader1, Reader2 and Reader3) I would to create a program which can do this:- a) Reader1 being plug into USB1, it will prompt me this message "Reader1 is at USB1" b) Reader2 being plug into USB6, it will prompt me this message "Reader2 is at USB6" c) Reader3 being plug into USB2, it will prompt me this message "Reader3 is at USB2" OR is it there are no orders on detecting which reader at which port. Example: Reader1 plug into USB6, it will be show this message "Reader1 is at USB1" While Reader1 is still at port USB1, I plug into Reader2 at USB5, it shows me "Reader2 at USB2" So which one? Is there any examples in C++ or .net used to detect USB ports? Any help, i am kind of confuse!

    - how to remove from registery I have a buggy IM installed on my machine (obviously mine)... it seems that it is partially installed and now no matter how many times I say no to digital signature it still try to install it.... anyhow.... how can I remove it from my registry... it seems that it tries to install four miniport IM filters ( I know why)... when I go through my computer->hardware->device manager... I see that there are 4 miniport driver installed under my network with yellow sign beside it... if I try uninstall it from there I get the error that it may require reboot before uninstall but reboot doesn't help... so again, how and where in registry/directories should I do the cleanup... & is there anyway to test the driver before installing it, I test by installation... I've already located some of the IM under a directory in HKEY_LOCAL_MACHINE\System\currentControlSet\Services but not so sure if I can delete them...

    - Need help with printer Driver and UI. I have been working on a printer driver that is supposed to work similar to the Microsoft Office Document Image Writer. Basically I need to capture the printed pages as bitmaps and then bring up an application so the user can view them. After working with the exmaples in the DDK I seem to have a version of it working. Do I need to create a port monitor for something like this? I noticed that the Document Imaging Writer uses a local port. I connected my driver to a local port but it will not work when I switch to another user. The print spooler says the print job has failed. If I connect it to FILE: then it will work but I don't need the file that it creates. What I am currently doing is capturing the bitmaps im ImageProcessing of oemuni.dll. I then spawn my viewing app in OEMEndDoc. Should I be doing this in OemUni or should it be fired up in OemUI (or in the port monitor)? Thanks, Bob Herzberg Tag: How to block an irp Tag: 54877

    - Porting problem from XP/2k to w98 - Walter Oney's framework - please give me an insight Hi all, I appreciate very much any comment that could give me the solution or an insight . I've a driver that communicates with my USB device. It is a monolithic kernel driver based on Walter Oney's framework. It has been created using WDMWIZ.AWX and has some code copied from chap12\loopback and uses Generic.sys. It works fine at Win XP and 2K. But, running on Win 98 I'm getting a Blue Screen with the message: (If I press any key after that message I can continue using the Windows) Fatal Exception OE has occurred at 0028:C002B814 in VXD NTKERN(01) + 00009C18. The current application will be terminated * Press any key... I think I did everything right: 1- I changed the Driver.h and Generic.def file from Generic Project (commenting the line //#define WIN98SAFE and the exports from .def) 2- generic.sys and wdmstub.sys are installed together with the driver 3- I launch wdmcheck.exe and everything seems to be ok. Then I tryied remove almost all functionality in the driver just returning STATUS_SUCESS from StartDevice. Then I got the same Blue Screen At the End. I removed almost all functionality the drive has just return STATUS_SUCESS from AddDevice Then I got the same Blue Screen again Thanks Very Much Tag: How to block an irp Tag: 54873

    - PCMCIA memory window access question Hello all we have a 16-bit pcmcia card that has 2 memory windows - one Attribute and one Common memory. Attribute memory is 8-bit access whereas common memory is 16 bit. Access time reported in the tuples is 200ns. All memory window accesses are done using a "mapped" memory window (returned using MmMapIoSpace) If the driver uses the PCMCIA_INTERFACE_STANDARD->ModifyMemoryWindow command to change the common memory access timing and also set the common memory window access to 16bit -things seems to speed up ~2X. However the common memory accesses still dont seem to be "truly" 16-bit as per the hardware engineer who reports seeing 2 8-bit accesses. Further, the speed improvement is only seen in XP platforms but not on Server2003 platforms. I did try the debug pcmcia.sys and WinDbg to see if any additional information regarding the accesses was printed .. but nothing stood out. So my question is : 1. What if anything does PCMCIA.sys do with the AccessTime reported in the device tuples (if no ModifyMemoryWindow is called or the inf changed to report 16-bit Common memory window). 2. What does ModifyMemory window do with regard to - a. pcmcia.sys behavior b. PCMCIA Adapter driver/hardware 3. Why do we not see the same performance improvement with Server2003 platforms ? 4. Is there a way to guarantee the card access time to be close to the 200ns that we need ? Thanks in advance --rr Tag: How to block an irp Tag: 54871

    - ndis IM and DifXTools...again I have been doing more investigation using the NDIS Filter IM driver sample from DifX 1.0 and this is what I have found. Note that I'm actually using dpinst.exe from DifXTools version 1.1, but using the sample from 1.0 since 1.1 only includes an NDIS Mux IM driver. If I have a clean XP machine (no versions of an IM driver previously installed) then using DPINST fails. An NDIS IM Filter driver package requires the miniport .inf file to be placed into a subdirectory of the protocol .inf file. So, using the IM Filter Sample from the 1.0 kit, the file and directory structure is: dpinst.exe netsf.inf passthru.sys NetworkIntermediate.cat miniport\netsf_m.inf Running dpinst.exe causes netsf.inf and passthru.sys to be copied to the driver store directory, but not the miniport\netsf_m.inf. When dpinst installs netsf.inf it creates OEMxx.inf and OEMxx.pnf entries in %windir%\inf. A netsf_m.inf entry (or corresponding OEMyy.inf and .pnf) is never created in %windir%\inf. Therefore, when netsf.inf is installed it never binds the miniport component of the NDIS IM driver because it can't find the miniport INF file, netsf_m.inf. According to dpinst.log the installation is successful, but the miniport is not bound. Note that if I pre-copy over miniport\netsf_m.inf to %windir%\inf then the installation proceeds as expected. Any ideas? I might have to brute-force this and copy the miniport INF file manually before the driver install occurs. Dan Tag: How to block an irp Tag: 54869

    - input resoultion change while capturing Hi, I wrote a streaming driver for my capturing device. My capturing device supports many resolutions and may switch while capturing, and as far as I know streaming devices usually do not change resolutions. In such case I have following solutions: scale down or up to static resolution, or generate black screen in case resolution changes. Programs of course handle all resolutions if I'll stop and start recording. Is there a way to handle? Or is there a better way to handle it than scale picture in driver for capturing device?

    - Raw Input from Mouse-like HID device Hi, I have a USB device that Windows treats as a mouse. However, I would like to use it to control another application instead of moving the mouse pointer. I have been able to get the raw data from the device using the raw input API and WM_INPUT messages, so I can control the application, but unfortunately the mouse pointer moves as well. Is there any way that I can somehow prevent the default processing of the information? Do I need to write some sort of driver to intercept the device before it gets recognised as a mouse? I am hoping that there is a very simple obvious solution that I've missed. Thanks for any help, Simon Tag: How to block an irp Tag: 54863

    - Start and stop via SCM not multiprocessor-safe? Hello, I found some strange behaviour, and I want to ask about your experience on that. Currently, I'm working on a driver which is not WDM, but legacy NT4. It is installed and uninstalled via the service control manager (SCM). As the driver verifier does some tests when a driver is unloaded, I have the following procedure in a test application for now: 1. Start the driver (equivalent to "net start <drivername>") 2. Open the device and do what I want 3. ... 4. Close the device 5. Stop the driver (equivalent to "net stop <drivername>") No. 1 and 5 will not be available in the resulting version of the driver, but they are there for now. Now, everything works for now, even the driver verifier does not complain. One of the persons I send the driver for additional testing did the following on his machine: He starts several instances (6, to be precise) of this test application above, to make sure that this case is handled correctly. Here, the "..." above (no. 3) is especially short, thus, the driver does not perform any work at all, but quits rather quickly. On my machine (uniprocessor), everything works fine, no problems at all. To my surprise, on his machine (hyper-threading) as well as on another machine (SMP), the system bugchecks. Most often, it bugchecks with a DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS, sometimes, there is a IRQL_NOT_LESS_OR_EQUAL. Unfortunately, I do not have a HT or an SMP machine here. Anyway, from the kernel dumps both send me, I found out that the driver was just executing something in the DriverEntry() routine. Every time, it bugchecks at different places, but it is always in the DriverEntry(), or in functions which are only called from there. If no. 1 and 5 above (starting and stopping the driver) is omitted, everything works perfectly. So, to me, it seems that No 5 (stopping the driver) in one instance of the test application, and no 1 (starting the driver) in another instance can occur simultaneously in the system on HT or SMP machines. Is this true? Is there anything I can do about it to prevent this? From my understanding, starting a driver via SCM will return with an error message if the driver is already loaded. Thus, if stopping has not yet taken place, another instance of the test app cannot start the driver, thus, the driver would never reach the DriverEntry() routine. But, from the crash dump, it must have reached the DriverEntry() routine. If the bugcheck would occur while operating the driver (no. 2-4), I would think it is a design flaw of mine. But this does not happen! Currently, to me, it seems like a design flaw of the OS, but I hope that I'm mistaken here. ;-) Any hints, suggestions, and remarks are welcome! Regards, Spiro. -- Spiro R.

    - User application video capture via kernel streaming? Hello folks, I've been hired for a in-house project (basicly an audio/video recorder, which can also do some realtime effects and output the processed audio/video in the while). Since I'm an extremely "low level" guy, and it was up to me to choose the hardware that would run my software, I implemented the audio part using the kernel streaming method (studying DirectKS Microsoft sample, although I rewrote everything from scratch). This gives low latency, but I'd have followed this road even if it didn't offer any such advantages over DirectSound. The reasons are simple, as I said I'm a low-level coder (and I'm not specialized on Windows, rather, often I work with proprietary hardware and OS), and I liked the more direct interfacing with the hardware, which makes my programming life actually easier and removes overhead (from my work and the CPU as well) and nonetheless makes programming much more fun! Now I've to write the video capture part, and I was wondering if an analogous exists? What is the lowest-level possible when doing video capture from any PCI card on Windows? It doesn't matter if, like the audio kernel streaming, it won't be supported on Windows 2005.. because this box will always run Win2K anyway, and on hardware chosen by me. Some, even many of you may disagree with me, but I like the idea of doing it the "lowest reasonable level possible", so I'd like to talk directly with the driver (I don't pretend to talk directly with the hardware in Windows, you see), and I'm already conscious of the disadvantages. Please, could any kind soul direct me to the right path to follow? I'm quite new to this kind of programming in Windows, and my battles with Google, MSDN and DejaNews didn't shed much light on the subject. :( Thanks! Andrea Tag: How to block an irp Tag: 54796

In USB2.0 spec......... section 5.9.... 5.9 High-Speed, High Bandwidth Endpoints USB supports individual high-speed interrupt or isochronous endpoints that require data rates up to 192 Mb/s (i.e., 3072 data bytes per microframe). One, two, or three high-speed transactions are allowed in a single microframe to support high-bandwidth endpoints. Best Regards, CLT Tag: How to block an irp Tag: 54794

    - How to debug Bsod 0x7B in scsi miniport during system boot ? Hello to All, I am developping scsi miniport driver for custom Flash under XP Embedded. When I boot from HDD the miniport successfully loads and windows mounts the Flash card (with compressed NTFS). When I boot from Flash card (I have BIOS int 13 support for Flash) I managed succesfully pass the miniport Init (DeviceEntry , FindAdapter, HardwareInitialize) and after a number of StartIO reads to sector 0 and Read_Capacity I get BSOF 0x7B : i.e. *** Fatal System Error: 0x0000007b (0xFC938640,0xC0000034,0x00000000,0x00000000) The devnode for device is created: DevNode 0x81288008 for PDO 0x8128b538 InstancePath is "ROOT\FlashDrv\0000" ServiceName is "FlashDrv" State = DeviceNodeStarted (0x308) Previous State = DeviceNodeEnumerateCompletion (0x30d) DevNode 0x81288c98 for PDO 0x812881e0 InstancePath is "SCSI\Disk&Ven_Compulab&Prod_Primary_Flash&Rev_1001\1&2c231adf&0&000" ServiceName is "disk" State = DeviceNodeStarted (0x308) Previous State = DeviceNodeEnumerateCompletion (0x30d) The BSOF comes from nt!IopMarkBootPartition. My flash partition is active and it boots with non miniport version of driver, so I conclude that the MBR and BootPartition is OK. I compared debug trace of HDD and Flash boot processes and found the match till the crash point . After the crash point the HDD version issued read sector 63 request. I don't know why the kernel can't read boot partition properly. And the only tool for debug that I have for now is this forum. What I chaecked: 1) The Hardware layer Initialize and reads Flash card properly. 2) The MBF is valid and the boot partition is marked as active. 3) I cheked for a conflict with atapi.sys (booting without attached HDD or removing atapi.sys from the system) 4) My ARC path is multi(0)disk(0)rdisk(0)partition(1) and it is the only one that works (not SCSI or signature). I stuck with this problem for a week and don't know what to do. There were a copuple of people at this forum that had the same problem , but they hadn't posted their solution . Any help or advice will be appreciated ! Regards, Konstantin. Tag: How to block an irp Tag: 54791

******************************************************************************* INACCESSIBLE_BOOT_DEVICE (7b) During the initialization of the I/O system, it is possible that the driver for the boot device failed to initialize the device that the system is attempting to boot from, or it is possible for the file system that is supposed to read that device to either fail its initialization or to simply not recognize the data on the boot device as a file system structure that it recognizes. In the former case, the argument (#1) is the address of a Unicode string data structure that is the ARC name of the device from which the boot was being attempted. In the latter case, the argument (#1) is the address of the device object that could not be mounted. If this is the initial setup of the system, then this error can occur if the system was installed on an unsupported disk or SCSI controller. Note that some controllers are supported only by drivers which are in the Windows Driver Library (WDL) which requires the user to do a custom install. See the Windows Driver Library for more information. This error can also be caused by the installation of a new SCSI adapter or disk controller or repartitioning the disk with the system partition. If this is the case, on x86 systems the boot.ini file must be edited or on ARC systems setup must be run. See the "Advanced Server System Administrator's User Guide" for information on changing boot.ini. If the argument is a pointer to an ARC name string, then the format of the first two (and in this case only) longwords will be: USHORT Length; USHORT MaximumLength; PWSTR Buffer; That is, the first longword will contain something like 00800020 where 20 is the actual length of the Unicode string, and the next longword will contain the address of buffer. This address will be in system space, so the high order bit will be set.

    - Confusion about AVStream Properties I'm confused about the declaration of properties in an AVStream driver. The samples and the documentation seem to contradict each other, as do the code I've found through Google. Let's take an example. We're writing, among others, a TV tuner driver. Looking in the Europa sample, in the analog tuner properties, we find, among others: DEFINE_KSPROPERTY_ITEM ( KSPROPERTY_TUNER_CAPS, AnlgTunerCapsGetHandler, sizeof(KSPROPERTY_TUNER_CAPS_S), sizeof(KSPROPERTY_TUNER_CAPS_S), NULL, NULL, 0, NULL, NULL, 0 ), DEFINE_KSPROPERTY_ITEM ( KSPROPERTY_TUNER_MODE_CAPS, AnlgTunerCapsGetHandler, sizeof(KSPROPERTY_TUNER_MODE_CAPS_S), sizeof(KSPROPERTY_TUNER_MODE_CAPS_S), NULL, NULL, 0, NULL, NULL, 0 ), Notice the two "sizeof" entries. According to the documentation, the first one is supposed to have the minimum size needed to identify the request. The second one is supposed to have the size of the data being read and written. In both of these entries, BOTH sizes are set to the full structure, which includes both the KSPROPERTY structure that identifies the property, and the data to be read/written. I'm conviced the sample is wrong. Further, if we look at the docuemntation for KSPROPERTY_TUNER_CAPS and KSPROPERTY_TUNER_MODE_CAPS, in BOTH cases the return value is documented as a single ULONG. When we copy the structures above into our own AVStream analog tuner driver, KSStudio fails to get the properties. Single-stepping through the code, I see that the upper-level drivers are returning STATUS_BUFFER_TOO_SMALL. We know that the analog parts of the Europa sample have never been tested, so I have no reason to believe the code above is actually correct. Further, I suspect from other property samples that the first size should actually be sizeof(KSPROPERTY), and the second size should actually be sizeof(ULONG). Does anyone within the sound of my voice have a WORKING AVStream tuner driver? Can you share with me the definitions of your KSPROPERTY_ITEMS? -- - Tim Roberts, timr@probo.com Providenza & Boekelheide, Inc Tag: How to block an irp Tag: 54781

    - What is the correct way to handle banding in OEMUNI print driver? Hi, I am having trouble getting my Unidrv plugin to handle banded bitmaps correctly. If I set the print to 100 DPI then my ImageProcessing gets 1 whole bitmap per page. However, if I set it to 300 DPI then I first get what appears to be the top 1/4 of the image. After that I get a few calls to ImageProcessing indicating blank bands and then that's it. The rest of the bitmap never appears. No matter how many pages are printed I just get a 1 partial bitmap, a few blanks and then that's it. Is there some argument that needs to be set to request the next band get sent? Also, how do I know when the last band for an image is received? Thanks, Bob Herzberg Tag: How to block an irp Tag: 54780

    - Updated version of ezusb.sys ? My version is 1.1 from 2001 / 2002 from cypress website Hello, can someone tell me if there is a newer / improved version of ezusb.sys then version 1.1 which can be downloaded from cypress website ? I saw the latest change was in september 2001. I googled around and read, that on http://www.devicedriver.com/ they write, you shouldn't use it for production because of bugs. Is this still valid today or were the mentioned bugs removed from current cypress code ? Is it worth buying a license ? What kind of bugs are inside the code ? Another question on IOCTL_EZUSB_BULK_READ: I often see that as size for the DataBuffer 0x8000 is used. Increasing it further to 64 KB seems not to work. Why this limitation ? Is overlapped reading supported ? Any other ideas how i can further increase bandwidth (currently 17 MB/s, with external IFCLK of 24,576 MHz) ? Regards, Martin Tag: How to block an irp Tag: 54778

    - Enlarging existing PE sections Hi, Introduction: ****************************** I am trying to extend an existing section of a PE, in addition to updating the â??DataDirectoryâ??ies and section RVAs I have to update the resources RVAs and the import and IAT/INT tables RVAs, as for what was just mentioned everything works fine. Still, it is not enough for an unmanaged program to work ( managed assemblies are satisfied with the changes just described ). The Problem: ****************************** Several assembler opcodes refer directly to the IAT: when executing an imported API ( of an external DLL such as Kernel32 ) the CALL opcode ( 0xFF15 ) refers ( by an RVA ) directly to the IAT, e.g. FF15[four bytes resembling the RVA to the IAT], this call will not execute properly if a section was enlarged causing the IAT RVA to change. To fix this all of the RVAs associated with CALL opcodes should updated as-well, this require doing some dis-assembling: 1. How can I find the starting points of any unmanaged functions in the â??.textâ?? section? 2 .How can I distinguish existing assembly code with some other metadata? 3. Is it possible to get from the CPU the assembly opcodes it supports ( and the size of each )? If so how? Is there a specification or is there some other way of extracting the supported opcodes directly from the CPU? Any ideas, suggestions or pointers would be appreciated ( please donâ??t direct me to the PE structure documentation found in http://msdn.microsoft.com/...

    - Data validity and timeliness with PCI bus master transactions My question is about data validity and timeliness with PCI bus master transactions. I have a bus master PCI device. The kernel mode driver programs the DMA controller on the bus master device to transfer data from the deviceâ??s memory to the hostâ??s system memory. When the transfer is complete (the deviceâ??s internal DMA FIFOs empty), the device generates a PCI interrupt to notify the host. At this point, the ISR schedules a DPC, which performs some handling of the completed transfer and possibly invalidates the cache for that system memory region. I would like to know at what point a PCI bus master driver can expect, with 100% certainty, the transferred data to be in system memory. Is it ridiculous to imagine that the ISR/DPC processing could happen before the host PCI bridge can shuffle all of the data into system memory? Am I being paranoid? I would like someone who has intimate knowledge of this process to either ease my concerns, or give me a little direction. Thank you, Lou Rohan Tag: How to block an irp Tag: 54752

    - Multiple Handles To A PDO Ok, I'm attempting to do what 100 people have posted about before, but I'll ask about it anyhow because the answers have seem mixed. I am trying to basically implement this product: http://www.mks.zp.ua/shared-serial-ports.php. I would like to do it by using a filter driver that creates intermediate buffers with independant pointers in the buffers for each of the connected com ports. Meaning: App1: CreateFile("COM1",...) -> MyFilterDriver[Buffer1] -> \\Serial0 App2: CreateFile("COM1",...) -> MyFilterDriver[Buffer2] -> \\Serial0 App3: CreateFile("COM1",...) -> MyFilterDriver[Buffer3] -> \\Serial0 However, I am running into the problem that I have yet to be definitively answered: How can I create multiple handles to COM1. Unfortunately, I have to make this TOTALLY transparent so I can't change the applications connecting to COM1. I have tried doing things like "Device->Flags = Device->Flags & ~DO_EXCLUSIVE" to no avail. And APPARENTLY, when you attempt to open the second connection, no IRPs are sent to the driver at all. NONE, WHATSOEVER ... I thought this was kind of weird. Well, I know one of you smart guys out there might have some ideas. Any advice is appreciated.... ugh, I should have stuck to Windows GDI coding. - Bryan Berns Tag: How to block an irp Tag: 54745

    - DIFX 1.1 automatically starts drivers? According to the DIFxApp.doc: "For file system drivers, file system filter drivers and file system mini-filter drivers, MsiInstallDrivers starts the service supported by the driver if a system restart is not required to install the driver." This is the behavior I observe even though my .INF file specifically that I want the service StartType to be on-demand. Is there a way to let me decide when to start the service instead of DIFxApp?

    - IOCTL + XP SP2 In year 2000 I developed a simple Virtual Network Driver in order to exchange messages from/to Microsoft IP to/from my user-space application that performs my proprietary data-link protocol (on both serial ports and modems). IP exchanges messages with my NIC in the standard way and my application puts/gets messages into/from my NIC through DeviceIoControl() function. I use the same IOCTL method with 2 different NDIS_OIDs to put messages into the NIC and to get messages from the NIC. #define IOCTL_NDIS_QUERY_GLOBAL_STATS \ _NDIS_CONTROL_CODE(0, METHOD_OUT_DIRECT) The NIC was developed for Windows NT 4 (conforming to NDIS 4.0 miniport interface specifications) and it works also on Windows 2000 and on Windows XP. Now with Windows XP Service Pack 2 my application can correctly put into my NIC messages smaller than or equal to 278 bytes; when the application puts into my NIC messages larger than 278 bytes the messages that IP receives from NIC contain "dirty" information. What is the reason of this behaviour ? Maybe is it due to some kind of buffer overrun protection in Windows kernel message ? Thank you Paolo Puricelli Tag: How to block an irp Tag: 54729

i want to block an irp , and let the user mode program to decide whether
cancel the irp or let the irp goes on. The condition is no presume,whick
means it must interact with use.

Any advice will be appreciated!
