    - How can I get certification stored in WinXPX64? Which API do I use and it makes me to get certification stored in "WinXPX64"? I tried to use CertOpenSystemStore() and CertEnumCertificatesInStore() APIs. Some certifications stored in local computer, but I sometimes get no certification. I don't know what the reason is. Whether do I need to use other APIs, not these or not? Do these APIs not work completely? Does somebody help me to solve this issue? I need you some suggesstion. Thanks.

    - Strange Monitor behaviour and debug messages on win2k3 Hi there, I have a question, it seems that when I print and exaclty afterwords attempt a XcvDataPort() on the Monitor that has recieved my print data I get error 170 (requested resource is in use). On the debugger it I saw that this module gets loaded "pcl5eres.dll" and someone prints this debug information: "Entering SimpleDocumentPropertiesinside DDPS returning sizeofEntering SimpleDocumentPropertiesEntering SimpleDocumentPropertiesinside DDPS returning sizeofEntering SimpleDocumentPropertiesEntering SimpleDocumentPropertiesinside DDPS returning sizeofEntering " What is it? Does anyone what this data means and why such a think could be happening. Thanks Adam Tag: How to support DRM in AVStream? Tag: 91433

    - Printer driver problem on Vista I have developed a printer driver that runs on Vista, for some reason when I print a lot of pages (more than 1000); The OS becomes unstable, and some of OS exes become corrupted! For example (task manager)!; And some of the folder security gets changed (you canâ??t access folders that you were allowed to access). And when you restart the OS it will not restart!!! I will have to reinstall VISTA again. Any suggestions of what the problem might be will help? Tag: How to support DRM in AVStream? Tag: 91432

    - save string functions at IRQL > PASSIVE_LEVEL? I'm porting a big old driver to KMDF. I use some strcat()/strcpy()/sprintf(), often for internal diagnostic messages. They are now deprecated, and the recommended kernel mode replacement RtlStringCch*() functions are bound to PASSIVE_LEVEL. So what is your meaning about the best solution: Leave everything as it is and disable compiler warnings ? Or write my own strcpy_s()/strcat_s()/sprintf_s() ? Tag: How to support DRM in AVStream?

    - register 32-bit dll in 64bit driver INF Hi, I'm trying to trigger registration of a 32-bit dll during a 64-bit driver installation. The following is an extract of the relevant parts in the INF. [XX_Device.ntamd64] ... CopyFiles=...,xx32.CopyList.ntamd64 ... RegisterDlls=xx.RegisterDlls.ntamd64 [DestinationDirs] ... xx32.CopyList.ntamd64 = 16425 ; %SystemRoot%\SysWOW64 [xx32.CopyList.ntamd64] xx123.dll,,,0x0100 [xx.RegisterDlls.ntamd64] ... 16425,,xx123.dll,1 After the inf installation, my 32-bit dll (xx123.dll) gets copied correctly to the SysWOW64 directory, but it the regsvr of the 32 bit DLL was not successful.

    - Does Longhorn driver work for W2K3 or Vice Versa Hi, I'm porting my driver to Longhorn, it's a boot-loaded driver supporting W2K3 32bit, W2K3 x64 and W2K3 ia64. Now we need to support Longhorn on all 3 platforms. Since for W2K3 support, I've built 6 drivers (free/checked, x86/x64/ia64). If for Longhorn, I build another 6, that'll be a lot. My questions are: 1. If I use WDK to build a driver for Longhorn in WDK Longhorn build enviroment, could that driver run in W2K3 on same platform ? 2. As a boot-loaded driver, to support Longhorn x64, it needs a embedded signature in driver file. If I do so, could this driver run in W2K3 x64 ? Tag: How to support DRM in AVStream? Tag: 91390

    - DTM client configuration - is Autologon required? I successfully installed all components of DTM. I then decided to run some tests on sound card drivers currently used by computer on which I installed DTM client (this PC is running Windows XP pro if it matters). All these drivers are signed by Microsoft, so I expected that all test should complete successfully. Was my expectation wrong? Because they all failed. Looking at the test errors I see this several times: ================================= Failed to Wait For Autologon Error Code 0 (The operation completed successfully) Resolution Waiting for autologon in session 0 failed. If you have tasks depending on that session to be present then those tasks will fail until someone logs on to the session. ====================================== Does it mean that PC where DTM client is installed should be configured for Autologon? If yes - what user name should I use? I noticed there is DTMLLUAdminUser created by DTM Client installation, but if this has to be used - what is the password for this account?

    - VISTA Install Windows Drivers (Hardware-First Scenarios) I need to install drivers on VISTA and XP. I will provide a CD containing the drivers. As documented in the SDK and the WHDC site, I have added in my autorun.inf a new directive supported by VISTA, "hardwareid". This is my autorun.inf: [AutoRun] open=setup.exe [DeviceInstall] hardwareid= VID_413C&PID_5128, VID_413C&PID_5128&MI_00, VID_413C&PID_5128&MI_01, VID_413C&PID_5128&MI_02, VID_413C&PID_5128&MI_03, VID_413C&PID_5128&MI_04 DriverPath=\Drivers With VISTA, I am expecting the the "Found New Hardware Wizard" is stopped when I insert the CD containig the drivers, and launch my setup.exe that will preinstall the drivers (using the DIFx DPINST.exe) then give back the hand to the "Found New Hardware Wizard". But this is not the case. What is wrong with my autorun.inf. Olivier Tag: How to support DRM in AVStream? Tag: 91379

    - NDIS: ProtocolUnbindAdapter() gets called at IRQL DISPATCH_LEVEL on Vista I got a problem, where ProtocolUnbindAdapter() of my IM driver gets called at IRQL DISPATCH_LEVEL on Vista, consequently causing a bugcheck 0x7C with 0x14,0x02,0x00,0x00 parameters when calling NdisWaitEvent() to wait for NdisCloseAdapter() to complete asynchronously. I'd like to know, why this can happen (most likely it's my programming error, but still), if the documentation clearly states that ProtocolUnbindAdapter() is called at PASSIVE_LEVEL IRQL. Also, the Debugging Tools documentation must be updated probably, since it doesn't reflect 0x14 parameter in the 0x7C bugcheck documentation. Additionally, when I specifically enable "DbgPrint buffering" parameter in GFlags utility and reboot the system and it crashes with a full memory dump, WinDbg then displays nothing when issuing ! dbgprint command. The nt!kdprint* buffers are empty for some reason. Thanks. Tag: How to support DRM in AVStream? Tag: 91378

    - KMDF inconsistent compiling: order of struct { } members differs I'm writing a KMDF-driver with an IoCtl-Interface. For each IOCTL-code I have defined a C-structure which describes the data passed between driver and the application. These structures interpret the data buffer "inBuf" and "outBuf" on both sides of DeviceIoControl(). So I have several "typedef struct { ... } " declarations. These are located in a separate header .h-file, which is included both in the driver sources and the application sources. So it is garanteed that driver and applications use the same buffer-structures. PROBLEM: I have found at least one struct {}, where the compiler changed the field order, when he compiles the driver. Example: typedef struct { DWORD result; DWORD long_value; char string_value[MAX_STRINGPARAMLEN]; } MyRecord ; When I compile the APPLICATION and declare a variable "mybuffer" MyRecord mybuffer ; then the fields have physically those offsets: mybuffer byte 0..3: member ".result" mybuffer byte 4..7: member ".long_value" mybuffer byte 8..11: member ".string_value" = pointer to character-array = address of mybuffer byte 12 mybuffer byte 12 ... space for string This is as it should be: struct fields are allocate in the order they were defined. BUT when I compile the DRIVER, then there are those offsets: MyRecord mybuffer ; mybuffer byte 0..3: member ".result" mybuffer byte 4..7: member ".string_value" = pointer to character-array = address of mybuffer byte 12 mybuffer byte 8..11: member ".long_value" mybuffer byte 12 ... space for string So the order of members is NOT like defined, the members ".long_value" and ".string_value" were exchanged! The consequences are of course catastrophic, since the driver interprets the integer "long_value" as pointer to the character array "string_value" => end of live as we know it. Thanks for reading so far, I hope the problem is clear now. I searched a lot, but found no #pragma settings which could influence the ordering of struct-members. Only struct-aligning can be modified, but this is not my problem. Some more facts: - I use WinDDK 6000 - driver and application are compiled within the same run of the BUILD-utility - its a checked build for x86 and WinXP platform. - build environment is also an x86 machine with WinXP.

    - USB HID Lower Filter Driver issue under VISTA Hi, I have a problem under MS VISTA with a USB HID filter driver (I developped) attached as low filter on the USB common class generic parent driver (usbccgp.sys) for a USB keyboard device with extra keys. The goal of my filter driver is to change the behaviour or inibit some extra keys of the keyboard. The principle of the filter is the following: it change the HID codes output for the requested keys using a remapping table set in the registry (bytes of code to replace/ bytes of replacing code) and comparing incoming codes and replacing if codes are matching the ones for the keys. Inside the filter driver, the codes are catched thru IRP_MJ_INTERNAL_DEVICE_CONTROL IRP, then IOCTL_INTERNAL_USB_SUBMIT_URB control code, then URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER function. This filter driver works fine under Windows XP all version. But, now, under vista the filter is installing and running (i can see this thru debug outputs), but it doesn't filter anything: it doesn't catch anymore the function URB_FUNCTION_BULK_OR_INTERRUPT_TRANSFER even if i can see this URB with a sniffer (WDMSniffer). I am not a specialist in driver development and i don't understand what could have changed under Windows Vista comparing to Windows XP ? Does somebody has an idea?

    - NDIS 6 RSS: mapping between CPU number, MSI message, and queue I am working on an Ethernet miniport driver, and am confused about RSS. Suppose the NIC has 16 MSI-X messages and it supports 16 receive queues. According to the NDIS spec, the NIC should compute the target "CPU" as follows. Target CPU = indirection_table[hash & (table_size - 1)] & (# of receive queues - 1) + base cpu number. Computing this target CPU number is straightforward. But, how should the NIC map this number onto a specific receive queue and also the MSI message to generate an interrupt? The indrection table entries as well as the base CPU number may change over time according to the RSS spec. How does NDIS know that the NIC is interrupting the expected CPU?

    - comparing all HW drivers on 2 servers Does anyone know of an easy way to compare the device drivers on 2 systems?

    - Stream Class Custom Video Format Problem Greetings, I am trying to create a custom video format for a USB camera driver based on the Stream Class. I currently have support for RGB24 and RGB8 which works fine for just looking at the video stream. However, I need to support some extended information that I believe is best done via a custom format (namely 16 bit monochrome images and some extended timing information). This custom format is consumed by a specific usermode DSHow filter I am also writing. Everything starts off well: the format is negotiated and UM sink filter gets the expected format information. The pins connect and the stream opens (i.e. my camera gets a SRB_OPEN_STREAM and completes successfully). When I transition into run however, I never get any SRB_READ_DATA calls. I can easily still use the RGB24 and RGB8 formats so I know that the support code around the different formats is working. But there is something about this new format that I am missing. I suspect that I was relying on some KS behavior that is no longer present now that I have left the cozy KSDATAFORMAT_SPECIFIER_VIDEOINFO world. To implement my new format, I created two new GUIDs: MEDIASUBTYPE_MYCAM_RAW and KSDATAFORMAT_SPECIFIER_MYCAM_RAW_INFO There is an info structure to hold the format information: typedef struct tagMYCAM_RAW_INFO { // whatever... }MYCAM_RAW_INFO; And a data range and format: typedef struct tagKS_DATARANGE_MYCAM_RAW { KSDATARANGE dataRange; // I include nothing here because there is no "range" to speak of. The camera // only supports whatever its current settings are. } KS_DATARANGE_MYCAM_RAW; typedef struct tagKS_DATAFORMAT_MYCAM_RAW { KSDATAFORMAT dataFormat; MYCAM_RAW_INFO formatInfo; } KS_DATAFORMAT_MYCAM_RAW; The data range is static KS_DATARANGE_MYCAM_RAW StreamDataRange = { // KSDATARANGE dataRange; { sizeof (KS_DATARANGE_MYCAM_RAW), // ULONG FormatSize; 0, // ULONG Flags; [doc: ignored] 0, // ULONG SampleSize; [doc: ignored] 0, // ULONG Reserved; [doc: must be 0] STATICGUIDOF(KSDATAFORMAT_TYPE_VIDEO), // GUID MajorFormat; MEDIATYPE_Video STATICGUIDOF(MEDIASUBTYPE_MYCAM_RAW), STATICGUIDOF(KSDATAFORMAT_SPECIFIER_MYCAM_RAW_INFO) } }; It is possibly that my use of KSDATAFORMAT_TYPE_VIDEO (which I though was required for capture pins) is triggering some assumptions somwhere? Any thoughts would be most appreciated. Best regards, Tom Udale Tag: How to support DRM in AVStream? Tag: 91324

    - WaveRT/WaveCyclic miniport usage and Vista certification We developed a virtual sound card driver and want it certified by Microsoft. The purpose of the driver is to capture audio stream and then service that we wrote sends it over the local network to networked speakers for playback. So the driver itself doesn't work with any hardware. Our current implementation (we support Windows 2000 and Windows XP 32 bit at this time) uses WaveCyclic miniport. We just started work on supporting Vista and got our driver working under Vista with some minor changes. We are still using WaveCyclic miniport. However, this document http://download.microsoft.com/download/9/c/5/9c5b2167-8017-4bae-9fde-d599bac8184a/DrvCompat_Vista.doc says: ========================== The following list summarizes some key requirements for audio drivers: · Implement Universal Audio Architecture (UAA)-compliant audio devices. · Implement audio drivers _as WaveRT_ miniport drivers. · Implement up-to-date digital rights management (DRM) support. ========================== Does it mean that if our Vista implementation uses WaveCyclic miniport we will not be able to get it certified? Also: who should I address this question to in Microsoft to receive authoritative answer? I emailed to whqldt@microsoft.com but so far haven't received even an acknowledgement that my email has been received. Tag: How to support DRM in AVStream? Tag: 91322

    - Output sequence for WPP software tracing Moin, I use WPP software tracing in my driver. For each trace line the first item shown is the CPU number in brackets. I'm wondering if there is a output sequence for those trace messages for the same time stamp. I'm currently analyzing a problem within my driver. The driver has a queue of messages with numbers in sequence. For any reason I see the messages fetched in a different order: [3]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89528008 READ cmd=0x82ff nr=0x4fcf [3]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89528008 READ cmd=0x82ff nr=0x4fd1 [1]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89337E68 READ cmd=0x82ff nr=0x4fce [2]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=8987D8F8 READ cmd=0x82ff nr=0x4fd0 I would expect the following order: [1]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89337E68 READ cmd=0x82ff nr=0x4fce [3]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89528008 READ cmd=0x82ff nr=0x4fcf [2]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=8987D8F8 READ cmd=0x82ff nr=0x4fd0 [3]08EC.16B0::01/30/2007-13:05:25.839 [driver]CAPI(173): PutMsgToIrpBuffer: IRP=89528008 READ cmd=0x82ff nr=0x4fd1 Is it simply a sequence issue caused by WPP ?

    - NdisRegisterDeviceEx() and CreateFile() security settings. Hi all Ndis 6 and Vista... I am using NdisRegisterDeviceEx() with as SDDL of "D:P(A;;GA;;;SY) (A;;GA;;;BA)(A;;GRGW;;;BU)(A;;GRGW;;;WD)" and it returns STATUS_SUCCESS. With a symboliclinks viewer I can see my device. But, when I try to open it with CreateFile() is using GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL I get the error: 'The request is not supported'. I have tried it with a 0 SDDL too with the same result. I am logged in as Administrator but this needs to work for users too. The old function, NdisRegisterDevice() works on Vista with my Ndis 5.1 driver. Doeas anyone have any ideas? I looked at the netvmini code that ships with the 6000 DDK and dont seed any reason for my code to fail. Thanks in advance for any suggestions on this. Tag: How to support DRM in AVStream? Tag: 91317

    - Vista 64 bit: HowTo receive origin inf file location? Hi! I need to receive the origin inf file location (path) through my CoInstaller dll when installing a hardware device. I´ve done that in the past using SetupDiGetSelectedDriver and SetupDiGetDriverInfoDetail. Doing it the same way on Vista 64 bit the path points to \Windows\inf. But I need the origin path. Is that somehow possible? Thanks, Nick Tag: How to support DRM in AVStream? Tag: 91315

    - hInstance field in PROPSHEETPAGE structure: MSDN doc not correct ( This is maybe not the right place to post this, but I lost almost a whole week because of it, so I hope it will be helpful to someone: The "hInstance" filed in the PROPSHEETPAGE structure must not only be set when you use the "pszIcon, pszTitle, pszHeaderTitle, or pszHeaderSubTitle members" like specified in the MSDN (see below) but also when you specify a resource template in the pszTemplate member (the WIndows CE documentation is apparently correct) Win32 docu: (http://msdn2.microsoft.com/en-us/library/ms652419.aspx) hInstance: Handle to the instance from which to load an icon or string resource. If the pszIcon, pszTitle, pszHeaderTitle, or pszHeaderSubTitle member identifies a resource to load, hInstance must be specified.

    - UpdateDriverForPlugAndPlayDevices fails - Please HELP Hi, I want to install a driver for non-PnP printer. For this I create and register a devnode for my device. Then I try to call UpdateDriverForPlugAndPlayDevices to update the drivers for the PnP devices. I expected to see my printer added but the UpdateDriverForPlugAndPlayDevices failed instead. The driver was installed but the printer was not on the "Printer and Faxes" page. If I add manually "PortName" and its value under "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\Printer\0000\Device Parameters" and then call UpdateDriverForPlugAndPlayDevices I have the printer installed. The problem is that the "Device Parameters" key appears after calling UpdateDriverForPlugAndPlayDevices. I cannot create the "Device Parameters" key manually because I am not allowed to. There should be a way to add the PortName parameter somewhere/somehow so that the printer installation to succeed. Are there another settings that I should add in order to get the printer installed correctly? Thanks a lot Tag: How to support DRM in AVStream? Tag: 91284

    - Intel ICH8 chipset doesn't response a DMA ack....(Vista) Folks: I was porting my FIR driver to Vista. My FIR driver work fine on my SIS EV board (both XP and Vista). My Custom used INTEL ICH8 chipset (for mobile). XP worked fine but Vista didn't work. During FIR negotiation, each computer will send/receive 2 bytes data (command and address) and 4 bytes FCS check code. Normally, FIR will send/receive a 6 bytes data (2 bytes data and 4 bytes command). I used LA to monitor DMA cycle and found out Vista didn't response the 5th time DMA ack. The FIR negotiation failed. Then repeated the error. Anyone knew how to monitor DMA operation ? I mean once I start DMA transfer. DMA should move data automatically. How did I know which steps DMA operation was wrong ? There is a strange situation: I installed XP and Vista in the same HD. There is two OS I could choose during booting. If I entered XP then reboot, changed to Vista (without unplug power). My FIR worked fine. If I removed my power core then plug, booting in Vista. The FIR driver failed to connect. Anyone can give me an advice ? Thanks Tag: How to support DRM in AVStream? Tag: 91282

    - HID mouse, digitizer device/driver Hi to kernel gurus! I have custom HW (non HID) connected to PC via USB + software system which calculates Tablet PC- like stylus position. The goal is to provide valid mouse and digitizer input form kernel mode. As far as I understand I have to provide valid HID reports to OS. I have to create HID minidriver which does not have any real HW behind , but receives coordinates form NT service. 1) Is HID minidriver an appropriate solution ? 2) In case I would like to provide mouse input will I be able to communicate with my driver form my software ? I understand that OS exclusively locks mouse driver stack. 3) Should I implement separate driver for mouse and digitizer? 4) Can anybody give a reference to the useful driver sample? 5) What is the best way to communicate between my HID driver and my software? (HID reports, CreateFile() , Pipes, Section) Thank you in advance, David. Tag: How to support DRM in AVStream? Tag: 91269

    - SetupUninstallOEMInf() FAILS on Vista x86 We have a custom installation utility for a USB device that performs the following actions on Vista x86 : 1/ Installs the .INF and driver using SetupCopyOEMInf(). 2/ Removes the device using SetupDiSetClassInstallParams(DIF_REMOVE) 3/ Removes the corresponsing oem??.inf and oem??.pnf for the device Questions : 1/ We want the installation utility to remove the files in the DriverStore\FileRepository directory as well so we are using SetupUninstallOEMInf(SUOI_FORCEDELETE). This call fails with error code 0x57 (The parameter is incorrect. ) How can we fix this ? 2/ Inspite of the fact that the files in DriverStore\FileRepository are not being deleted, when Vista reenumerates the device, it does not find the .INF file for installing the driver. The driver is not signed. Doesn't the OS look for drivers in DriverStore\FileRepository ? Tag: How to support DRM in AVStream? Tag: 91268

    - Help! Print Processor Clipping Path Help! I am writing a generic print processor to draw text to the bottom of every print job, like a watermark. On some drivers, the clipping path is set to enclose the original document text, and exclude the rest of the pate. For example, if I draw text in the print processor in the center of the page, but there is only one line of text in at the top of the page of the original document, the text drawn in the print processor will be clipped. I have tried to expand the clipping path, trying almost every clipping function, including removing it altogether. However, I can not change the bottom dimension of the clipping rectangle, no matter what I do. I can change every other dimension of the rectangle, though. Is there something I can do to change the clipping path in a print processor? Modifying the driver is really not a good option, and this is supposed to work for any driver.

    - DIFx Issue for Composite USB Devices We have a composite USB device. It has 2 interfaces each belonging to a different setup class and is driven by a single driver. Following are some details about the devices. INTERFACE #1 : HardwareId=USB\VID_vvvv&PID_pppp&MI_00 SetupClass=Modem .INF File=x.inf FunctionDriver=modem.sys (inbox) LowerFilterDriver=mydriver.sys (installed by .INF file) AddService Line in .INF as as follows : AddService= mydriver, 0x00000000, Device.AddService [Device.AddService] DisplayName=%SERVICENAME% ServiceType= 1 StartType = 3 ErrorControl = 0 ServiceBinary = %12%\mydriver.sys INTERFACE #2 : HardwareId=USB\VID_vvvv&PID_pppp&MI_01 SetupClass=Port .INF File=y.inf FunctionDriver=mydriver.sys (installed by .INF file) AddService Line in .INF as as follows : AddService=mydriver, 0x00000002, Device.AddService [Device.AddService] DisplayName=%SERVICENAME% ServiceType= 1 StartType = 3 ErrorControl = 0 ServiceBinary = %12%\mydriver.sys PROBLEM: We are using DifXCmd.exe sample from the WDK to install and remove the drivers and the device itself and we are having the following issue. Installation for both these interfaces devices go through fine. However when we attempt to remove the devices DIFxCmd always fails for the interface #1. We have tried quite a few things but nothing seems to work. >From the setupdi.dev.log the failure seems to be in a function in setupdi.dll SetupDiGetSelectedDriver() which fails with the error code ERROR_NO_DRIVER_SELECTED for INTERFACE (E0000203) #1. Is this a bug in PnP Manager or DifX APIs that manifests itself when uninstalling drivers for composite USB devices? Tag: How to support DRM in AVStream? Tag: 91261

Hi,

I would like to implement support for DRM content in a AVStream based
driver. The DDK only mentioned about how to declare support for a WaveCyclic
or WavePCI miniport driver, and nothing about AVStream. Can anyone provide
any info? Thanks

You need to contact Microsoft about this. Only trusted and signed drivers
are allowed to participate in a DRM graph. You can't sign them until they
are tested, and you can't test them until they are signed.
