    - Devicepath from SetupDiGetDeviceInterfaceDetail After enumerating device interfaces for GUID_NDIS_LAN_CLASS and getting the interface detail, I get the devicepath like- DevicePath = \\?\....#{ad498944-762f-11d0-8dcb-00c04fc3358c}\{86ff7813-229e-4030-905e-dff4822330dd} I want the adapter name, which is actually the "ServiceName" value of the registry key: HKLM\Software\microsoft\Windows NT\CurrentVersion\NetworkCards\<number> This ServiceName (128bit GUID in W2K and later), matches with the "{86ff7813-229e-4030-905e-dff4822330dd}" part I get in the devicepath using SetupDiGetDeviceInterfaceDetail call. Is this always the case and a safe assumption? Tag: Getting SID While Deleting Files Over LAN. Tag: 50383

    - SCSI SRB FLAG does not make sense - SRB_FLAGS_NO_DATA_TRANSFER Hello everyone, In the DDK, page SCSI_REQUEST_BLOCK (System Support for Buses->SCSI Bus->Reference->SCSI Bus Structure->SCSI_REQUEST_BLOCK), the SrbFlags can have a flag set as 'SRB_FLAGS_NO_DATA_TRANSFER'. The page says, "Indicates no data transfer with this request. If this is set, the flags SRB_FLAGS_DATA_OUT, SRB_FLAGS_DATA_IN, and SRB_FLAGS_UNSPECIFIED_DIRECTION are clear" Now when I look at the include file srb.h, this flag is '#define'd as 0x00000000. Can anyone explain this? If I am going to test the flag using the following statement: if( srb->SrbFlags & SRB_FLAGS_NO_DATA_TRANSFER ) { // do all this } I will never have the block executed. This got to be a bug, true or not? Thanks. Tag: Getting SID While Deleting Files Over LAN. Tag: 50372

    - microsoft os descriptor (usb) Can anyone help me locate the information on how to implement the Microsoft OS descriptor in a USB device? I found some "os descriptor" defines and structs in the 2003 DDK which, when returned by my device does seem to make WinXP SP2 to query for more information. However, I have not found (ddk help, microsoft.com, google, etc.) any documentation whatsoever on how to correctly/fully implement this. http://www.microsoft.com/whdc/system/bus/usb/USBFAQ_intermed.mspx <quote> The Microsoft OS descriptor is a set of data structures that IHVs can use to include extra information in device firmware, information that Microsoft OS descriptor-enabled applications and operating systems can extract. The data is extracted by vendor-specific USB requests to the device as indicated in the OS Descriptor specification. The information retrieved will provide the operating system and/or applications with additional information about the device and its special features. For additional information about the Microsoft OS descriptors, please visit USB Architecture and Driver Support. </quote> Thanks in advance Tag: Getting SID While Deleting Files Over LAN. Tag: 50359

    - USB port monitor error 1223 Hi there, I'm working on a custom language monitor for a USB printer. I've found that if the printer is unplugged then plugged back in, any WritePort calls to the USB port monitor result in failure with an error 1223. Obviously I can't write to the printer while it's unplugged :) but once it's plugged back in, is there anything I can do to get the port talking again? If I delete the job that is failing, the next one writes to the printer without a problem. -- Matt Kane mkane@zebra.com Tag: Getting SID While Deleting Files Over LAN. Tag: 50358

    - IRQ Sharing causes multi-function adapter to lock PC We are having problems with a third party vendors card. Everytime it shares an IRQ with another PC device, it locks the controller. We've been able to recreate and fix the symptoms by freeing up the sharing IRQ resource. The vendor is trying to integrate a LSI mulitfunction chip that passes about 120MB/s (yes, 120 Mega Bytes per second) on the PCI bus. This is near the theroetical bandwidth of the PCI bus. One caveat that we have is that for stability purposes, we have to use the "Standard PC" HAL instead of one of the ACPI HAL's available with XP/2K. This is for compatibility purposes with legacy devices integrated into our product. Our ultimate goal is to get the device to share an IRQ. We aren't going to rewrite their driver. Are there any BIOS settings or OS fixes that might help to let this device share an IRQ? Any suggestions? Anyone? Thanks. Tag: Getting SID While Deleting Files Over LAN. Tag: 50354

    - Listing files that comprise a display driver Hi, One of my current tasks is to list out all the files that comprise a display driver, and the final piece of code should work on both WinXP and Win2000. I have written a piece of code that will list out the files of a driver, given the driver inf file, and the device id. Now my task is to figure out the inf file of the display driver installed on the system. When I use EnumDisplayDevices, the field DeviceKey gives me some information about a location in the registry to the driver registry area within HKLM\SYSTEM\CurrentControlSet. Would like to know if I could and if yes, how, could I use the information in the DeviceKey to get to the inf file of the driver... Can anyone help?? Thanks, Radha.

Now I have got WinXP and with applications like WordPad or StarOffice the printed text is simple black. With other applications like Acrobat Reader the text is still gray. Is there something wrong with the driver (It's original Windows-driver)? Is there something wrong or missing in the gpd-file?

    - Checking File and Print Sharing Hi - I'm creating an installation program that will install a VB.NET program and an instance of MSDE on an unknown desktop (commercial application). The install will include the MSDE redistributable files (and it will launch the MSDE Setup.exe to install MSDE). I've read that "Except on Win 98 and Millennium, file and print sharing must be active" How can my install program ensure this (programmatically)? More specifically: Where (registry setting or elsewhere) do I check for these settings, and what name-value pairs are valid? Is this the correct approach?

    - VFW Streaming Transfer under WME Hi, I have port a 32bit, user-mode only VFW driver from bravodo sample to an user-mode only Video Capture Driver. I understand that VFW using two transfer mode - Frame (Single Capture) and Stream. For eg, Dorgem, use Frame (Single Capture), However, AMCAP and WME seem use Stream (WDM based). My only problem now remain is on STREAM transfer mode Cause it quite long, in summarized, I used as follow : on DVM_STREAM_PREPAREHEADER - return DV_ERR_NOTSUPPORTED, so suppose client will supply the buffer on DVM_STREAM_ADDBUFFER - add into queue, return DV_ERR_OK When the data ready, I use DriverCallback (with MM_DRVM_DATA). But however, the data seem not pass-through client driver, the preview and/or output screen show nothing, and the WME FPS (Frame per Seconds) show zeros, but show encoding... and my debug show DVM_STREADM_PREPAREHEADER, then DVM_STREAM_ADDBUFFER repeated for about 40 times, then my driver fill the buffer and callback, and this repeat. FYI, I'm using separate thread procedure to supply the data into VHdr (buffer queue), synchronized through semaphore (replace STI/CLI for H/W board), and notify client with DriverCallback (MM_DRVM_DATA etc). I understand that WME, AMCAP etc use somekind of VFW wrapper for WDM, How do I verify that my Callback worked ? Any recommend for a sample WDM client with source-code for me to easy debug (for,eg, the callback did called correctly) ? Thank in advance wp Tag: Getting SID While Deleting Files Over LAN.

    - Problem with NDIS transport driver Hi, I have miniport driver which is using NdisMIndicateStatus function to send some "events" (my own status values) via transport driver into application. Everything works as long as I don't bridge my connection with any other network interface using standard Win XP bridge. When my interface is bridged then transport driver is no longer receving status indications from my miniport driver. Are they filtered by the bridge driver? Is there a solution to that or I have to to change the whole mechanism of sending events up from miniport driver? Thanks for help Marcin Tag: Getting SID While Deleting Files Over LAN. Tag: 50347

    - USB: multifunction device beside usbser.sys Hi Because of many people recommended to use usbser.sys instead of writing my own COM mapping driver I did so, and it works so far. My problem now is, that I should be able to use the device's second configuration - so I think I can name some kind of multifunctional device. For getting quick results about feasability, I used libusb-win32 (latest version). I tried to reset the device, enumerate all for getting a new handle set config but got an error. I think it must be usbser.sys that claims the device befor I can do it. How can I solve the problem. Any idea. Many thanks in advance Robin Tag: Getting SID While Deleting Files Over LAN. Tag: 50338

    - problem using a standalone device object with NDIS Hello, I have a problem when using 'NdisMRegisterDevice()' in my NDIS driver. I use this call to create a standalone device object so that my application can communicate with my driver. Using this, I can communicate with my driver fine from my app. However, the file handle that my application creates to talk to my driver does NOT get notified when I register to receive device notifications using 'RegisterDeviceNotification'. However, if I create a handle using the REAL device name (obtained by using the SetupDixxx functions), my app properly receives the notifications. I can't use this handle tho', 'cuz NDIS owns it and my driver won't received Irps sent to it. The basic problem I'm trying to solve is this: if the device is unplugged WHILE the app is running, the app needs to close the handle to allow the driver to unload.

    - Getting quick IP address on P2P RNDIS network There is a small problem that we've run into, which I hope somebody can help us with. We have a USB device, which supports RNDIS and that causes an XP machine to create a separate network for it. The device also creates a "remote" node on that network essensially establishing point-to-point network inside the device itself. Now to the problem, how do we quickly assign IP address to this network? I am looking for any suggestions - from totally legal to semi-legal. So far this device is restricted to a lab environment, but having fully supported solution is obviously preferred. Static IP assignment is out of question. So is auto IP as it is too slow. We need to be able to assign a address in a matter of seconds or even faster. Also a requirement - multiple instances of this device can be connected to the same machine and they all have to sit on separate networks and don't conflict with each other. The only solution that I can think of at a moment is to have the device being a DHCP server for its own net. Problem: multiple devices can be connected to the PC and there must be a solid algorithm in place to avoid any conflicts. I was also told that IPv6 would solve this issue. This is very generic problem and I am sure there are good solutions to it. Can anybody offers any suggestions or refer me to relevant RFC or something? Any help would be appreciated. Thanks! -- Max.

    - DIFx Framework - HOWTO Hi All, First, I have only a basic understanding of the certificates, signing, etc. so please excuse me if some question appears to be a stupid one :-) I'm evaluating the MS DIFx framework as to make a single file installation of the driver I've made. In connection with this I have tried to set-up an installation through DIFx framework but have some troubles with it. I get the following error in DpInst.log file for every INF file in the driver: "ERROR: driver package 'drive:\path\INFFILE.INF' is unsigned. Error code 0x800B0100, No signature was present in the subject." Could somebody explain me what is the right way to set-up the installation. - As far as I know only the cat file should be signed not all the files in the driver package... Follows a short description of how I've tried to make the installation: In the INF file I have included the requested CatalogFile and DriverPackageType sections: CatalogFile=CBMA.cat DriverPackageType=PlugAndPlay The content of CBMA.cdf file is: [CatalogHeader] name=CBMA.cat [CatalogFiles] CBM.dll=CBM.dll OEMUI.dll=OEMUI.dll OEMUNI.dll=OEMUNI.dll CBM.ini=CBM.ini CBM_CT1000II.INF=CBM_CT1000II.INF CBM_CTS300.INF=CBM_CTS300.INF CBM_PPU700.INF=CBM_PPU700.INF CBM1000II.GPD=CBM1000II.GPD CTS300.GPD=CTS300.GPD PPU700.GPD=PPU700.GPD ttfsub.GPD=ttfsub.GPD CBMA.HLP=CBMA.HLP eula.txt=eula.txt From this file I have successfully created .cat file and subsequently signed it with a test certificate obtained through makecert.exe and cert2spc.exe... After that I copied DpInst.exe in the driver directory and made eula.txt and dpinst.xml files. Subsequently when I ran DpInst.exe I received the described error.

    - DPC has high latency only with SMP Hallo, i'm back with my DPC latency problem: i'm testing my driver on an SMP machine, and 4 or 5 times every second when in the isr i request the dpc, i find that the old request is still in queue.

    - [Q] how can i get the CR3 value? Hello all. I have a question about getting cr3 value. (page directory base address) In softice, the 'PAGE' command shows the cr3 value exactly.

I think this is because my driver is called in a user process, not in kernel. so, my question is this. is there any way to get the cr3 value of the kernel?

    - network link speed Hello, does anyone know how the link speed is determined by Windows when attached to a wireless network? I know Windows queries the Ndis driver using OID_GEN_LINK_SPEED, which is supposed to return the max Tx rate. In a wireless network, the max rate is determined by the Service Set. Therefore, I would assume that when associating with a particular Access Point, I should always get the same link speed. However, I've seen cases where the link speed changes between 1, 2, 5.5 & 11Mbps - even though I'm still connected (i.e. no disassociation/reassociation occurs). My service set consists of a single Access Point, which is configured to use all 4 rates (i.e. they're all marked Mandatory in the beacon parameter set).

Here's how the initialization of the HW_INITIALIZATION_DATA structure looks like: ULONG DriverEntry(IN PVOID DriverObject, IN PVOID Argument2) { HW_INITIALIZATION_DATA InitData; ULONG Status; ULONG i; for (i=0; i<sizeof(HW_INITIALIZATION_DATA); i++) ((PUCHAR)&InitData)[i] = 0; InitData.HwInitializationDataSize = sizeof(HW_INITIALIZATION_DATA); InitData.AdapterInterfaceType = PCMCIABus; InitData.DeviceExtensionSize = sizeof(MY_DEV_EXT); InitData.NumberOfAccessRanges = 2; InitData.HwFindAdapter = FFS_FindAdapter; InitData.HwInitialize = FFS_HwInitialize; InitData.HwStartIo = FFS_StartIo; InitData.HwResetBus = FFS_ResetBus; InitData.HwAdapterControl = FFS_AdapterControl; InitData.HwInterrupt = FFS_Interrupt; InitData.HwAdapterState = FFS_AdapterState; InitData.HwDmaStarted = NULL; Status = ScsiPortInitialize(DriverObject, Argument2, &InitData, NULL); __asm int 3 return(Status); } The bare minimum inf file to install my bare minimum driver looks like this: [Version] Signature="$WINDOWS NT$" Class=MTD ClassGuid={4D36E970-E325-11CE-BFC1-08002BE10318} Provider="Mike" DriverVer=08/14/2004 [DestinationDirs] DefaultDestDir=12 [Manufacturer] "Flashcard"=DeviceList [DeviceList] "PCMCIA Flashcard"=DriverInstall,PCMCIA\UNKNOWN_MANUFACTURER-0000 [DriverInstall.NTx86] CopyFiles=@ffs.sys [DriverInstall.NTx86.Services] AddService=ffs, 2, ServiceInstallSettings [ServiceInstallSettings] DisplayName = "PCMCIA Flashcard" ServiceType = 1 StartType = 3 ErrorControl = 1 ServiceBinary = %12%\ffs.sys LoadOrderGroup = SCSI Miniport Dependencies = PCMCIA AddReg = ServiceRegistryEntries [ServiceRegistryEntries] HKR, "Parameters\PnpInterface", "8", 0x00010001, 0x00000001 The driver is ment to be pnp compliant as the PnpInterface registry key and the presence of the HwAdapterState-function indicate. After the driver is installed and a memory card is pluged in, the drivers DriverEntry() function is called and ScsiPortInitialize() returnes a value of zero. (Which seems to be ok). But after that, no other function will be called! The main question is: Why is no other function than DriverEntry() called? Acording to MSDN this may happen if PnpInterface is present but the driver is not installed as a service for the device. Which leads directly to the question: The above inf file should install the driver ffs.sys as service (with the name 'ffs') for devices of type PCMCIA\UNKNOWN_MANUFACTURER-0000. Is this the case? Or do you see any mistakes? (I used msdn and Oneys WDM book to 'tinker' the above inf file together, but it's well possible that i've missed something... ?!?) I have no idea why my driver does not initialize proper. Maybe a legacy driver would be a better idea than a pnp driver... Please let me know if you have any advice.

    - USB Driver : 0xC0000B00 + 0xC000A00 errors with Isochronous OUT Endpoint when ASAP is specified ! Hi, My device supports an Isochronous OUT Endpoint, set to 895 bytes/ms. Also I would like to fully use this endpoint (ie : fill in all Isochronous OUT frames each millisecond). To do this, I implemented a stuff that sends 4 pending URBs to the USB Bus driver. Each URB also gets completed but some are completed with 0xC0000B00 error (USBD_STATUS_ISOCH_REQUEST_FAILED). For those URBs that fails with this error, Iso packets (that do not have data) are told to be in error (0xC0000A00 = USBD_STATUS_BAD_START_FRAME), whereas all URB are sent with the USBD_START_ISO_TRANSFER_ASAP flag. Does anyone knows this kind of problem, and is there any trick to fix this problem ? Thanks by advance ! Sebastien Tag: Getting SID While Deleting Files Over LAN. Tag: 50258

    - Using DIFxApp for Net Client install I've been trying to use the DIFxAPP code to install our NFS Client Device driver and have been running into problems. The DIFxAPP code requires a WHQL digital signature.for use with Windows 2000 and XP. Since we have no hardware we cannot take advantage of that program. An Authenticode signature can be used for Windows Server 2003, but apparently not for Win2k and XP (According to the Authenticode doc anyway). Has anyone else run into this problem? Any workarounds? Does anyone know why a WHQL digital signature is a requirement? Any idea if this requirement might be relaxed in the future? The error that cat get past is 0x800B0100L which is "No signature was present in the subject." I have supplied an Authenticode signiture, so I'm guessing that it wants a WHQL digital signature, correct? Regards, Duane Johnson WRQ, Inc. Tag: Getting SID While Deleting Files Over LAN. Tag: 50255

    - Terminal Server, virtual audio driver, and lossless audio I was unable to locate a better newsgroup, so if there is a better place to post this question, please let me know. I am working with streaming audio over a Terminal Services connection in Windows 2003 Server. However, the application we'd like to use will be used in an audiological setting, so having lossless audio is of paramount importance and there doesn't appear to be a way to configure the virtual audio driver to use a lossless codec for transmission across the network. My question, then is this: Is there a way to configure the virtual audio driver for Terminal Services to use lossless compression? If not, to whom would I speak in order to have this option implemented in a future version? Thank you for your time in this matter. Tag: Getting SID While Deleting Files Over LAN. Tag: 50254

    - How does NDISWAN work? Hi, does somebody know how NDISWAN makes decisions which WAN link is best for sent packet? MSDN says: "In an NDIS WAN environment, NDISWAN examines the header of the descriptor of a send packet and determines over which link the packet will be sent", but I would like to know what item of packet descriptor header is crucial.

    - binplace integration to the build utility Hello, Is there a way to integrate the binplace utility to the build utility of the ddk? For example the WPP tool is integrated and to use it you need to add the macro "RUN_WPP= $(SOURCES) -km" to the "source" file. I could not find any documentation about it in the ddk or the Internet.

    - 2 device interface questions Hi, i use SetupDiGetClassDevs to build a list of devices, and then i use SetupDiEnumDeviceInterfaces to enumerate device interfaces. however, if i do not specify DIGCF_DEVICEINTERFACE and use the same classguid that i use for SetupDiEnumDeviceInterfaces, the enumeration fails. aparrently if i do not specify DIGCF_DEVICEINTERFACE, i get a list of setup classes. what is the use of this if i cannot enumerate device interfaces with the resulting list? my second question is simpler: i am making an api to handle the device driver interfacing. a user needs to have something that he can pass to the api that i am making, in order to say: open a connection to that specific device. does he need to use the detailed name that is returned by SetupDiGetDeviceInterfaceDetail? or is there a simpler way to do this? kind regards, Bruno.

    - Microsoft Mirror Sample Driver hi all i am using Microsoft Mirror Sample Driver. all is working fine, and i am able to capture the desktop (with minor additions). however, i am experiencing a runtime side-effect. all combo-boxes in the operating system do not open normally, rather, they open only over where the mouse is. i commented out all the DrvXXX except for DrvEnablePDev DrvCompleteDev DrvDisablePDev DrvEnableSurface DrvDisableSurface DrvAssertMode (which seem to be the minimal requirement for a Mirror Display Driver). after i remove the driver and re-boot, the side-effect goes away. has anyone else ever experienced this side effect? can some one help me? assaf Tag: Getting SID While Deleting Files Over LAN.

I can not get the correct SID of the impersonation user??
