    - DrvDocumentPropertySheets Hi When I get a call to DrvDocumentPropertySheets (PrinterDriver) and the reason is PROPSHEETUI_REASON_INIT. What do I have to do? ... I have to create the propertysheet-pages... ok, that's obvious... and do I also have to copy the pdmIn? (so, can there be a pdmIn?) ... and what about the pdmOut? ... do I have to store the pdmOut-Pointer to store the data later? when? When I get another call to DrvDocumentPropertySheet with the Destroy-Reason? ... or do I have to store this earlier? Next question... how can I find out, if someone pressed OK and not Cancel? ... MSDN says only, that the value of lParam is not zero, if someone pressed OK or Cancel... but how can I find out what it was? ... ok, that's a lot of questions... it's enough if you can answer at least one :-) thanks a lot MR Tag: Audio and Video Drivers on XP Tag: 56294

    - who stores the printer driver settings? Hi Little question about printer driver settings: When you open the printing dialog e.g. in an application like Notepad, then you can make some settings for the current print job. (so the DEVMODEW doesn't leave the applications-process)... but when you open the "printers and fax"-folder (I don't know the exact name of this in english), you are changing the global settings for the printer. Every new job starts then with those settings. But who does store this? Is this the job of my printer driver or does windows automatically do it? If I have to store it myself, how could I find out, what application caused my propertysheets to be created? And what does DrvConvertDevmode return if it should return the "defaults" ... these stored settings? thanks for your help MR Tag: Audio and Video Drivers on XP Tag: 56292

    - wFrameRate of KSPROPERTY_TIMECODE_S not returned to user app Hi all, I've got a WDM capture driver that supports the KSPROPERTY_TIMECODE_READER property set that returns the timecode correctly within the dwFrames portion of the TIMECODE structure but wFrameRate doesn't seem to be passed back with the value I filled in. In my driver I get a pointer to the output buffer to fill in as follows:- PKSPROPERTY_TIMECODE_S pTimecode = (PKSPROPERTY_TIMECODE_S)pSPD->PropertyInfo; I make sure the output buffer is big enough before I return it:- if (pSPD->PropertyOutputSize >= sizeof(KSPROPERTY_TIMECODE_S)) And then I write to the output buffer after I work out what to return as follows:- pTimecode->TimecodeSamp.timecode.dwFrames = dwFrames ; pTimecode->TimecodeSamp.timecode.wFrameRate = wFrameRate ; pTimecode->TimecodeSamp.timecode.wFrameFract = 0 ; For a PAL source I set wFrameRate to ED_FORMAT_SMPTE_25 which should be 0x1198. In the user app I call the GetTimecode() method of the IAMTimecodeReader interface on my capture filter/driver. I first initialise a TIMECODE_SAMPLE structure with unique values, e.g. wFrameRate = 0xDEAD. Then a pointer to this structure is passed to the GetTimecode() call. After the call the dwFrames is updated correctly with the correct timecode. However, wFrameRate is still set to 0xDEAD. I've proven that the output buffer of my driver has wFrameRate set to 0x1198 which corresponds to ED_FORMAT_SMPTE_25 before the driver returns. The amount of data returned by driver is :- pSrb->ActualBytesTransferred = sizeof(KSPROPERTY_TIMECODE_S); I don't update anything else in this structure within my driver (e.g. I leave pTimecode->TimecodeSamp.dwFlags alone and indeed this is retuned with the same value I set in the user app of ED_DEVCAP_TIMECODE_READ which I also confirm in my app). Does anyone have ane ideas on what's going wrong? Thanks, Emyr Tag: Audio and Video Drivers on XP Tag: 56291

    - about virtual audio driver Hi,everyone: I need to write a driver or filter or something like that to capture the audio data between audio card and user mode application, for I have to have these data changed before they are send to audio card from user mode or to user mode from audio card. I think i should write a virtual audio driver, right? Considering that user mode applications are from third party, which maybe use DirectSound or Windows Wave API (WaveInXXX, WaveOutXXX etc), my driver has to support both of conditions. I have studied DDK example msvad\simple, but not sure whether it's a proper start for my requirement. Can someone tell me what should i do and where should i begin? Thanks in advance. rex Tag: Audio and Video Drivers on XP Tag: 56290

    - error - no object file generated Hi All, I'm trying to create a local Structure to store some network information in it... I have declared my struct as following: GLOBALS.H typedef struct _MyStruct { ULONG MyField1; ... long MyFiendN; } MyStruct, *PMyStruct; extern MyStruct g_MyStruct GLOBAL.C MyStruct g_MyStruct; NetMonitor.C <-- this is a new file that I have added to the Passthru structure. PMyStruct g_MyStruct; g_MyStruct->MyField1 = pAdapt->LinkSpeed; Then during the compile I get the following error: error C4700: local variable g_MyStruct used without having been initialized so I go to my NetMonitor.c and I make the following change: PMyStruct MyNetwork = NULL; MyNetwork->MyField1 = pAdapt->LinkSpeed; Then the system crashes that couldn't fill the object g_MyStruct->MyField1 and here is the error from dbgview: DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1) An attempt was made to access a pageable (or completely invalid) address at an interrupt request level (IRQL) that is too high.

    - XP SP2 1394 problem with PCMCIA cards We have a FireWire problem with our new IBM laptops thay are preinstalled with XP SP2. The problem is that the connection to the scanners we produce gets reset during data transfer. Afterwards the connection is lost. We have observed the same problem with an external harddisk. All device are able to install and function in a limited extend, but after a short period of operation they fail during data transfer. We have observed the following: When using SP2 with an Adaptec AWF-1430 card the above problem occurs. When installing the SP1 drivers with that card everything works fine. Furthermore, if we use the Adaptec 1430A card with SP2 everything works fine. However, the 1430A card is discontinued and replaced by the 1430 card. All other cards we have tried also fail to run on SP2, whereas the SP1 drivers seem to work just fine. Adaptec support has directed us to MS support claiming that you are responsible for developing the drivers for their 1394 PCMCIA cards. Tag: Audio and Video Drivers on XP Tag: 56261

    - AVStream : dynamic format change Dear All, I met some AVStream questions and described them as following Q1: How to change raw audio sampling rate in AVStream driver? I want to make sure my understanding is correct or not. step1 : receive a IO control from application program. step2 : use KsEdit to modify the datarange infos in this pin descriptor. step3 : reconnect this connection. Am I correct? Please let me know if I lost some points. Q2: How to support "dynamic format change" capability on one pin of an AVStream filter? Do I need to implement KSPROPSETID_Connection? What its items should (or MUST) I implement if the previous answer is YES? For example, KSPROPERTY_CONNECTION_PROPOSEDATAFORMAT, KSPROPERTY_CONNECTION_DATAFORMAT,... Any commnet and suggestion are very welcome and appreciated. Thanks, Edward Tag: Audio and Video Drivers on XP Tag: 56258

    - Asking for driver files Dear Sirs, I am trying to make my computer system(win me) to reconize the new digital camera(olympus d-535 zoom) I just bought. But, the disc that came with the camera won't download(error:-1603)and when just plugging the camera in, my computer asks for the millenium me disc for curtain files; 'USBNTMAP.SYS, USBSTOR.SYS, Musbport.pdr, olpubkcr.sys'. Since I bought my computer with this operating system already installed, I don't have a disc to retreive the information. What is wrong with my computer, or how do I get the usb\driver info?

    - KsProxy interface aggregation. Hi guys, I'm tearing my hair out on this one! I have a rendering minidriver, and I want it to implement frame stepping, which is IVideoFrameStep to user mode, and AM_KSPROPSETID_FrameStep to the driver. The code I'm working on already has examples of custom interfaces aggregated via KsProxy to do property pages. However, in all those cases, the property set ID is the same as the user mode IID - and it works fine. However, when it comes to trying to get my new interface working, nothing happens! More specifically KsProxy seems to instantiate the user mode COM object in my helper DLL, but it never queries that same object for IVideoFrameStep, and trying to single step in GraphEdit does nothing. I suspect the problem may be due to confusion between IID's and Prop set ID's. The .INF file for the driver registers the aggregated interface via KsProxy as follows: ;IVideoFrameStep HKCR,CLSID\%AM_KSPROPSETID_FrameStep%,,,%PlugIn_IVideoFrameStep% HKCR,CLSID\%AM_KSPROPSETID_FrameStep%\InprocServer32,,,mediaxks.dll HKCR,CLSID\%AM_KSPROPSETID_FrameStep%\InprocServer32,ThreadingModel,,Both ; N.B. IID_IVideoFrameStep is NOT the same as AM_KSPROPSETID_FrameStep ; There is no absolute requirement for User mode IID to be the same as property set GUID. ;AM_KSPROPSETID_FrameStep = "{C830ACBD-AB07-492F-8852-45B6987C2979}" ;IID_IVideoFrameStep = "{E46A9787-2B71-444D-A4B5-1FAB7B708D6A}" HKLM,%MediaInterfaces%\%AM_KSPROPSETID_FrameStep%,,,%PlugIn_IVideoFrameStep% HKLM,%MediaInterfaces%\%AM_KSPROPSETID_FrameStep%,IID,%REG_BINARY%,87,97,6A,E4,71,2B,4D,44,A4,B5,1F,AB,7B,70,8D,6A ; Note binary coding is for IID_IVideoFrameStep And since the property set is meant to be exposed on a pin, I've also got this little gem, which doesn't appear to be documented anywhere, but seems to be the way of indicating that the interface is meant to be exposed on a pin: ; Registry for interfaces [InterfaceRender.AddReg] HKR,,CLSID,,%CLSID_PROXY% HKR,,FriendlyName,,%mediaxm2v.DeviceDesc% HKR,PinFactory\0\Interfaces\%PROPSETID_CONNECTION%,,,%PROPSETID_CONNECTION% ; TODO - should the IID below be the user mode IID or the KS Propsetid? HKR,PinFactory\0\Interfaces\%IID_IVideoFrameStep%,,,%IID_IVideoFrameStep% (The propsetid_connection is there so we can suggest an allocator framing). In my user mode DLL that implements the plug in, I then have code very similar to the sample available on MSDN (which, ISTR is IAMCameraControl or such like). Most of the code is not that relevant, except, perhaps, the QueryInterface, which (not unsurprisingly) looks like this: STDMETHODIMP CFrameStepInterfaceHandler::NonDelegatingQueryInterface(REFIID riid, void ** ppv) { HRESULT result; CheckPointer(ppv,E_POINTER); PrintGUID("CFrameStepInterfaceHandler::NDQI", &riid); if (riid == __uuidof(IVideoFrameStep)) { MYTRACE(("IID_IVideoFrameStep\n")); result = GetInterface(static_cast<IVideoFrameStep*>(this), ppv); } else { result = CUnknown::NonDelegatingQueryInterface(riid, ppv); } MYTRACE(("CFrameStepInterfaceHandler::NDQI %08X\n", result)); return result; } Anyways, to cut a long story short, in my DLL, I see something like this from the debug output of my DLL, which indicates the COM object is instantiated, but unfortunately, none of the methods in it are called - and I don't get any debug from my methods or from my driver upon trying to frame step. CFrameStepInterfaceHandler::CreateInstance pOuter 009667DC CFrameStepInterfaceHandler::CFrameStepInterfaceHandler pOuter 009667DC CFrameStepInterfaceHandler::CFrameStepInterfaceHandler QI 00000000 CFrameStepInterfaceHandler::CreateInstance hr 00000000 pObj 00EC3E28 CFrameStepInterfaceHandler::NDQI: 00000000-0000-0000-C0-00-00-00-00-00-00-46 CFrameStepInterfaceHandler::NDQI 00000000 CFrameStepInterfaceHandler::NDQI: 00000000-0000-0000-C0-00-00-00-00-00-00-46 CFrameStepInterfaceHandler::NDQI 00000000 CFrameStepInterfaceHandler::NDQI: 56A868AF-0AD4-11ce-B0-3A-00-20-AF-0B-A7-70 CFrameStepInterfaceHandler::NDQI 80004002 Any ideas?

    - Help! I can't play Mpeg2-TS in graphedit Hi, I've modified the testcap.sys to be a MPEG2 transport stream minidriver. Then I follow the steps described in http://www.codeproject.com/directx/MPEG2_Capture_Device.asp?df=100&forumid=59308&exp=0&select=869492 to build the whole graph in graphedit. My minidriver can connect to Microsoft Mpeg2 demultiplexer successfully. It also reply every SRB_READ_DATA request without any problem. But the problem is the ActiveMovie just displays black windows. I think I may make some mistakes in configuring the demultiplexer because the example in the above website is for program stream instead of transport stream. Could anyone give me some advice?

Does anybody know how I can determine the physical spool file name attached to a specific job on the spool queue? On Windows 2000 it's built from the JobId but that is not the case on XP. I know I can get XP to revert to the old naming convention by setting Keep Printed Documents to True but I don't really want to have to impose that restriction on customers. I've checked the API for JOB_INFO_x structures but they don't seem to have a field containing the spool file name. Many thanks for any help you can offer, Bob.

    - INF file for ISA driver with multiple devices I have an old WindowsNT ISA driver with two CAN devices, I have rewritten the driver with pnp and power management etc. I want to create a INF file for the driver with the two devices - they have different IRQ and memory ranges. Is it possible ? if it is - how do i write the INF file, Can i use LogConfig to configure the hardware resources on both devices or do i have to use two INF files. I am only seems to receive the hardware resources for one device in START_DEVICE Thanks in advance! Tag: Audio and Video Drivers on XP Tag: 56221

    - USB configuration for simultaneous services Dear experts, I am looking for the source code of usbser.sys. I have 3g cellular supporting simultaneous services (e.g. Voice call, Video call, internet connection, Fax etc). I am looking for a sample of a USB configuration that contains 3 CDC and an Inf file, which install 3 modems in the device manager with the usbser.sys driver, the aim is to use microsoft drivers. I asked 'Walter Oney' and the answer was to use IAD which has OS version limitation (XP only) or to write one. So, my aim is to look for the usbser.sys sources and to fit it to support 3 CDC.

    - IOCTL within Kernel-Mode? I've got an DLL, which currently runs in user-mode, that I want to turn into an export-driver (kernel-mode DLL). The DLL uses IOCTL as interface to a device driver (SYS). Is it possible to use IOCTL within kernel-mode, too? If yes, which headers do I need and which TARGETLIBS do I need to specify in DDK's "sources" file? If no, do you know any mechanism that can partly reuse existing IOCTL code?

    - IoReportTargetDeviceChangeAsynchronous returns STATUS_PENDING Hi, my driver is using PnP custom notification to signal the app. Unfortunately, IoReportTargetDeviceChangeAsynchronous is returning STATUS_PENDING and the app never receives any of the messages. I'm fairly certain that my registration calls are correct with the same GUID messages. Any suggestions on what's happening, where to look, and a good way to debug (e.g., tools, etc. Spy isn't reporting anything (I may be using it incorrectly))?

    - NdisOpenfile( ) gives blue screen Thanks Dr. RonM for diagnosing all of us being patient. Infact you little misunderstood my requirements or i could n't explain it properly. I had to open file only & only once (after exchange of specific/special packet). Finally i got the solution...Packets passing NDIS passthru driver can have IRQL either PASSIVE_LEVEL or DISPATCH_LEVEL (as i have come to know).All i have done is call the NdisOpenFile() function when there is a packet with IRQL==PASSIVE_LEVEL. Hope this will help someone. Thanks a lot for suggestion/recommendations/ideas put forward by you people This helped me a lot Umer Tag: Audio and Video Drivers on XP Tag: 56207

    - ERROR_ACCESS_DENIED Hi, Sorry for re - posting the question!. Earlier I had written - I'm getting ERROR_ACCESS_DENIED when I try to open a handle to the non - standard HID USB keyboard for which I have developed a minidriver. So the answer I got is - "Use the standard way the HID minidrivers of Logitech, Kensington etc use. Add a second interface to the driver (aka a side exit). Logitech etc use that side exit to split the mouse data into standard movement and clicks for Windows and extra buttons which are routed through the side exit to the tray application which implements the special assignments like playing a sound or starting an application etc." Sorry..but am not very clear about what u said.. Can u be a bit more specific? Is there any article on internet where I can get some more information? I have two questions : 1> U said add a second interface.. U mean to say that I have to change the firmware to accomodate one more interface, give it a seperate guid and open a handle to this particular interface? In this case I will have to change the firmware. 2> I tried developing a driver br some third party software for teh same device with my current firmware. But it worked (its only an evaluation version!!). So I thought there s no need to change the firmware. Is it true that there is some other way of opening a handle to the device? Any comments on this issue will be of great help to me... Expecting your reply.. Thanks Tag: Audio and Video Drivers on XP Tag: 56203

    - Lockup debugging I've got a dual Xeon W2k3 box that locks up intermittently. I'd like to debug or crash it when it stops responding. Ctrl + double ScrollLock doesn't work. It's not convenient to have a debugger attached all the time. I wonder if the following will work. - I set /debug /debugport=1394 in boot.ini and boot the box - Once the box has locked up, I connect a 1394 cable to a laptop with WinDbg - I use WinDbg to debug or crash the box What are my chances to have WinDbg connected to the target machine when the latter is stuck - ie spinning at a high IRQL? Can anyone suggest hardware-based solutions to crash a PC with memory dump? Like a cheap PCI card, NIC or whatever, with two wires and a red button soldered to it? Though I am afraid the problem is in video drivers, so even if I managed to crash the computer, I won't get the memory dump anyway. Thanks Pete -- Tag: Audio and Video Drivers on XP Tag: 56200

    - MiniportQueryInformation From what I understood MiniPortQueryInformation is the function that exposed by the miniport-edge (upper layer of the IM) to allow Porotocol driver (above the IM) to query the NIC .. the function call translates to NdisRequest() function call. Now the question is do I use MiniPortQueryInformation function call if I want to query NIC info from within the IM or should I just call NdisRequest() function directly? Thank you for your help.

    - A DDK sample bug? or not? Hello, I noted a very common pattern/technique in the DDK sample code: In a dispatch routine for IRPs like IRP_MN_START_DEVICE, you initilize an event on the stack that the completion routine is supposed to set. After the call to the lower driver you wait on that event: status = IoCallDriver(deviceExtension->NextLowerDriver, pIrp); if(!NT_SUCCESS(status)) { ERROR HANDLING... } // // MS: Wait for lower drivers to be done with the pIrp. // Important thing to // note here is when you allocate memory for an event in the stack // you must do a KernelMode wait instead of UserMode to prevent // the stack from getting paged out. // if(status == STATUS_PENDING) { KeWaitForSingleObject( &event, Executive, KernelMode, FALSE, NULL ); status = pIrp->IoStatus.Status; } You probably have seen this technique. Seems OK? What I don't understand is what prevents the stack from being paged out by the time the completion code tries to set the event if that happens before the KeWait...() is reached. The only resolution I see is if it is guaranteed that the completion thread is the same thread of the dispatch routine (but then why bother with events at all...). What am I missing?

    - Does USB isochronous transfer have buffer alignment limitation? Dears, I meet one strange problem for USB 1.1 isochronous transfer. My test driver is based on the usb isochronous sample in XPDDK. The maximum packet size of isochronous endpoint is 1022. The driver sets the buffer offset of each ISO packet according to maximum packet size. After the driver prepares the internal Irp and urb for transfer, it calls IoCallDriver to pass request to bus driver. However, bus driver neither send isochronous IN command on USB bus nor return error status. The complete routine is never called. However, if the driver sets the buffer offset to 512 byte alignment for each ISO packet, bus driver performs the isochronous transfer well. Does USB isochronous transfer have buffer alignment limitation? If bus driver doesn't have this limitation, what's the possible reason for this problem? I have sufferred this bug for several days. I don't see any sample code aligns the buffer offset for usb isochronous transfer. Please give me some suggestions. Best Regards Jackal Huang Tag: Audio and Video Drivers on XP Tag: 56167

    - IoReportTargetDeviceChangeAsynchronous Availble on Windows 2000? Hi, Can you use PnP custom notification on Windows 2000? There's nothing on the MSDN, online or off, that I could find, that indicates that it's not useable for W2K. The only problem is that the function IoReportTargetDeviceChangeAsynchronous isn't defined in the W2K DDK libraries. It is however, in the Windows XP DDK libraries. If I build my drivers with the XP libraries, and don't use RtlVerifyVersionInfo with VER_SET_CONDITION (see http://www.microsoft.com/whdc/driver/tips/drv-tools.mspx#EBAA) or any other "XP-only" functions shouldn't the driver work in W2K?

    - Turning on a Device causes a Windows 98 mapped drive to fail ? We have written a Device Driver for a legacy ISA Interface Card with Visual C++ 5.0 and the Windows 98 DDK (Driver Development Kit), using Chapter 7 of Walter Oney's book "Programming the Microsoft Windows Driver Model". The device is an Ionosonde and is remotely controlled over a network by a drive letter x:\ mapped to UNIX PC. The Control software works OK at first but after switching on the Ionosonde a few times, via the Windows 98 Device Driver, the x:\ drive fails. There is no problem if the x:\ drive is mapped to a different UNIX server or when polling the local c:\ drive on the Control PC instead. Any help would be appreciated.

    - Strange error when starting a service... I am having a really strange problem that hopefully has a simple and obvious solution that I am just not seeing. I am installing drivers for a device, and I have to copy several drivers over in the process to System32\Drivers. In the INF file, I copy all of the driver binaries to the %12%\drivers directory, and all the binaries get copied to c:\winnt\system32\drivers (I've verified this post install). In the registry entries for the various services that I'm installing, they all contain "System32\DRIVERS\" and then the binary file name as the ImagePath key. All of the services have the exact same directory (there are no typos or anything, all are generated by the %12% in the install INF file). All but one of them work. One of them gives me an error when you try to start it that it can't find the file. Which is odd, because it's right there in the System32\Drivers directory. Here's the oddity. If I set the ImagePath to point to another directory - it works fine. If I then set it back to "System32\DRIVERS\filename.sys", it now works without a problem. Does anyone know what I am doing to copy this file wrong? Thanks in advance if anyone can help. Tag: Audio and Video Drivers on XP Tag: 56128

Sorry if this is not the right newsgroup. I haven't found any better
one. I have a video card and an audio card, a friend of mine installed
the drivers for me and they are perfectly working. Now I have lost the
CDs, I don't know the name of the manifactures, and I need to completely
reinstall the system (too full of crap). Could you tell me what I can do
to save on a CD the necessary files (already installed) so that after
formatting I can just add the drivers from those files/Cd?

Thanks,
