    - SPTI rejects valid requests I'm witing some low level CD access stuff (writing DAO in RAW mode and things). I'm mainly using SPTI, cos I'm developing under XP. The problem I'm having is that a number of calls are failing for no apparent reason. These calls work perfectly when I use ASPI as the transport (I choose to use ASPI or SPTI when my base level object is initialised - all the CDB construction and so on are in higher levels and identical). The 2 calls which I'm seeing give problems are Read TOC (ATIP) and ReadCD (with a -ve LBA). I've looked at the CDB and in both cases it is identical. The errors I'm seeing are Address out of Range (for Read CD) and 'invalid Operation for this track' for the ATIP reading. I cannot believe that something in Windows is doing this. But on the other hand, nor can I see anyting odd I'm doing with these particular functions. The Object proper is quite happy to use dozens of other functions (including ReadToc with other parameters!) and happily writes audio cds and DVDs and reads the same. Just these few functions ... Can ayone throw light on this? Iain Tag: create an event at ring0 level Tag: 40839

    - Map interface index from the IP Helper API to an intermediate driver miniport instance. Hi! Is there any way for an intermediate driver to find out (in either ProtocolBindAdapter or MiniportInitialize) what interface index (IP Helper API) it will get. In userspace I keep track of adapter by their iphlp index and I would like to make a call down an intermediate driver with that index instead of the name of the adapter. It would be awesome if each of my miniports instances could figure out that index on their own. Cheers! Tag: create an event at ring0 level Tag: 40836

    - ISR not called Iam writing a device driver for PCI card Iam using a interrupt. I have initialized the interrupt and connected the InterruptServiceRoutine by the call IoConnectInterrupt.Also the DPC object is initialized for the DpcForIsr routine by IoInitializeDpcRequest. In the interrupt service routine First checked for the interrupt whether it is from my card if it is not returned FALSE immediately. If it is from my card then acknoledged it. Then some processing is done. Then the DPC object is queued to continue the request processing by IoRequestDpc. Return TRUE from the Interrupt Service routine. When I debugged the program ISR routine is not called. Am I doing any mistake. Secondly when I restart the system, the system was hung.I think the problem is due to not disabling the interrupts in correct way.What am I supposed to do.

    - UPS minidriver Dll Hi I'm currently developing a UPS minidriver Dll for Windows XP The UPSTurnOff function has a parameter DWORD aTurnOffDelay The DDK describes the parameter as Specifies the minimum amount of time, in milliseconds, to wait before turning off the UPS unit's power outlets. Called by the UPS service, I get here 180 Does this mean that I have to wait 180ms before issueing the output to the UPS to shut down Does this mean that I have to issue the output 180ms long It CANNOT mean that the UPS has to turn off 180ms after issuing the output because XP has no even begun to shut down I assume this value is in seconds. 180s seems to be an appropriate value for shutting down XP Thanks for your help Tag: create an event at ring0 level Tag: 40819

    - OID problem Hi, I am developing a protocol driver. There I need to define my own WLAN OIDs. How it can be done. I have a driver developer manual from a chipset manufacturer. that chipset developer is providing some of his own OIDs. I am on Windows 2000. thought chipset developer provides his OID header files but as of now i don't have those. so thought if it is possible to write own OIDs. e.g. one of the OID provided by chipset manufacturer is OID_CURRENT_BSSID. I have some info from Driver Developement Manual for miniport drivers. Is there any way by which i can define these OID. regards, Puneet Tag: create an event at ring0 level Tag: 40813

    - How can I lock user memory at DISPATCH_LEVEL? Hi My driver has to do lots of Scatter Gather List DMA operations. This used to be ok at PASSIVE_LEVEL, but it becomes a problem when I try to use a system queue and call DMA operation in my StartIo routine. Before I can start DMA operation, I need call IoAllocateMdl() to build MDL for the user memory and call MmProbeAndLockPaged() to lock the user memory into the physical pages. According to DDK document, MmProbeAndLockPages() function can be called at DISPATCH_LEVEL ONLY when the memory is not pagable, but I have no way to guarranttee that the user memory is nonpagable, right Is there anyway I can get around this Thanks zhong Tag: create an event at ring0 level Tag: 40799

    - multiple virtual COM port support over USB I have a WinCE device that is able to connect to the PC via Active Sync over USB. It can also connect as a modem(but not at the same time). The drivers on the PC side for either of these expose a virtual COM port on the PC. I want to change my WinCE device side driver to add support for one more virtual COM port over the same USB connection. I have changed my device side descriptor to say it has two interfaces, but I'm having trouble enumerating two ports.

    - Problem using KeQuerySystemTime My goal is to inject a job id into a PS header using WMARKPS compiled in kernel-mode (for NT4.0). My development environment is WinXP Professional, VC++6.0, Windows DDK 2600.1106. 1.. Using the 'DDK checked' shortcut (on the start menu): 1.. I typed "set WINNT_40=1" 2.. After moving to " C:\DDK\WINDDK\2600.1106\src\print\oemdll\watermark_NT", I typed "build -cef". (I copied the watermark folder to watermark_nt, and modified the sources file so that watermarkps.dll would be compiled in kernel-mode). 3.. At this point I am able to install and use the NT version of WMARKUI and WMARKPS on an NT4.0 system. 2.. From this point I want to simply inject a PS comment that consists of a JOBID generated from the system time. 1.. In the PSCommand method of Command.cpp in WMARKPS I want to use KeQuerySystemTime(), but when I compile, KeQuerySystemTime() causes an undeclared identifier error. 2.. If I "#include <ntddk.h>" (or wdm.h), the compiler says that it can' t find the header files. 3.. If I "#include < C:\DDK\WINDDK\2600.1106\inc\wxp\ntddk.h>", the compiler gives me a bunch of redefinition errors. 4.. If I "#include < C:\DDK\NTDDK\inc\ntddk.h>", the compiler again gives me a bunch of redefinition errors. How can I get methods defined in NTDDK.H to compile?

    - IP Address Assignement Problem on WinME- A starnge one. Hi, I am facing a strange problem on WinME. I am connecting two USB Network Devices on My system running WinME. I assign x.y.z.1 address to first card (say Card1) and x.y.z.2 to second card (say Card2). Ping works on both the cards. Now I remove both the cards and connect card2 first. What I see is that the system has assigned x.y.z.1 address to this card2 and if I connect Card1 now the system assigns x.y.z.2 address to Card1. (Actually we would expect the system to assign x.y.z.1 addres to Card1 and x.y.z.2 to card2) Why the system is behaving this way? Is it any known issue on WInME or is there anything that I am missing in my driver or in INF file. Please help me in sorting out this issue. thanking you in advance. regards, Nazim Tag: create an event at ring0 level Tag: 40770

    - Microsoft Printer Language Monitor Hello All: The Story so far ---------------- I want to compress a PCL output file via a standard UNIDRV based printer driver in w2k. I need to do this so that a compressed PCL file is read by another custom tool which will extract and interpret the PCL Data. To do this, I need a language monitor with my unidrv based printer driver. According to my picture, The story goes that the pcl data is received in the language monitor from the print processor. The language monitor will compress and send the data to microsoft's own port monitor via the FILE port and the file is saved and compressed. Problem: -------- I have compiled Microsoft's own sample of a language monitor, namely the pjlmon package but I only could do this if I change the following: 1: There is a case statement with a syntax error using a ';' instead of ':' 2: The assignments to the function pointer types mismatch so I had to create wrappers which match those in the MONITOREX structure used in the sample. I installed microsoft's language monitor successfully after some hassle but I still have more issues. Namely: 1: I had to remove references to critical sections everywhere. 2: I had to remove a validation UpdateTimeoutsFromRegistry in the InitializePrintMonitor. My problem is that my WritePort in the sample is not being called. I have included some file output traces to check for this. I also see that in MSDN, docs state that InitializePrintMonitor2 is to be used for language monitors. It is not the case in MS's own sample. Does anyone have experience on MS Language Monitors who can shed a light upon my problem please? Thanks and Best Regards Duncan Camilleri Tag: create an event at ring0 level Tag: 40767

    - DiskPerf Crashes. Hi Guys I am using Win XP Pro SP1 for developing a simple device driver. As i am a beginner i wanted to test the DIskperf.sys provided in the DDK kit. I have two hard disks connected in my system say disk1 and disk2 disk2 is the secondary slave. so i install the diskperf.sys in disk2 .. as addfilter /device \disk2 /add diskperf.sys after that i restart the system then i can see that my disk2 is not at all recognized. To solve the problem i go to Device Manager,uninstall Disk2 and again do a scan for plug and play hardware. This seems to be a recurring problem. Any help is awaited...

    - DbgPrint in Irql=2 I had a debug print in the Irql = DISPATCH_LEVEL when I acquired spinlock. There was bug check "invalid address access at higher Irql, Irql = 2". I removed the print and I had no problem. Is it DbgPrint should not be called after acquiring Spinlock(before releasing lock) or my problem is just hidden. I know we should release spinlock as soon as possible but I just had print (only for testing). Is it bug to have print in spinlock. Tag: create an event at ring0 level Tag: 40760

    - working with multiple OS versions Hi All, The question is at the end. I have a PCI device + driver, which has to work on both Win-NT and Win-2K. I have 2 Drivers : A WDM driver for Win2K, and a Non-WDM driver for Win-NT. So, far everything is great. The 2 drivers has the axact same interface from the application point of view. The only difference is in the "CreateFile() method". So, naturally, I want to have one DLL for both drivers, and do the CreateFile() according to the runtime OS version. This works also very good. Here comes the problem : Up until now, I compiled the DLL on Win-2K, and ran it under both OS. Now, I want to compile this DLL, under Win-NT (I am not expecting to run this DLL on win-2K). I am expecting to have one code though. Now the following line does not compile !!!! "include <initGuid.h> The file axists, but I get some funny compilation error. Here I do not care for the GUID (I CreateFile() by the good old NT method), so I delete this line and everything works. Remember that I am expecting to have one code for the DLL. I want to do something like: #if (WINVER > 0x0400) "include <initGuid.h> #endif But for some reason, this does not work: On my Win-2K compilation machine, WINVER is also defined to be 0x0400. *************************** So here comes the question : How do I figgure out during compilation, which OS version I am compiling on ? I want to use some compiler variable. Thanks Maurice Tag: create an event at ring0 level Tag: 40754

    - KSPROPERTY_MEDIASEEKING_FORMATS / ksproxy!CKsProxy:QueryMediaSeekingFormats Hi All, In my continuing quest to implement IMediaSeeking in a stream class minidriver, it seems that the ksproxy itself (and not a component aggregated by it) will ask you which seeking formats you support (via KSPROPERTY_MEDIASEEKING_FORMATS), if you support KSPROPSETID_MediaSeeking on the device (and not on the pin/stream). However, I don't know where to stick the answer. The DDK docs on this are sketchy to say the least. I'm getting pSrb->CommandData.PropertyInfo->PropertyInputSize = 18 (= sizeof(KSPROPERTY)) pSrb->CommandData.PropertyInfo->PropertyOutputSize = 0 I've tried returning STATUS_BUFFER_TOO_SMALL (as per SRB_GET_DATA_INTERSECTION) and/or STATUS_BUFFER_OVERFLOW, but when I do that, I don't get any further requests. So, I tried returning STATUS_SUCCESS, but that resulted in ksproxy reading from address 00000004. Has anyone ever done anything with this? Max P? thanks for ANY help, Matt Tag: create an event at ring0 level Tag: 40753

    - Connecting to an USB-Device Hi !! I'm student of computer sciences in germany and work on a project in which I want to build some generic classes to list all available USB-Devices and to connect to any USB device. (Of course the developer has to know how to access the driver) I build a class to enumerate all USB devices and give it back as a list (like the USBView Example in the DDK). Now I want to open a connection to one of this devices. For this I need the GUID (Or at least it seems so. I just looked at the BulkUSB Example in the DDK), but I can't find a way to get it from Windows only having the device data i got from enumeration. Do you know a possibility to do that ?? Or perhaps another way to open the device... Or another way to get a list of all USB-Devices with their GUID... Thx for ANY help. Andre Tag: create an event at ring0 level Tag: 40752

However, I am having issues on our test laptop. Basically, if I insert a (previously uninstalled) PCMCIA network adapter, my ProtocolBindAdapter handler is never called, and my driver is thus not aware of the new network adapter. Rebooting the system makes no difference. Actually, in order for the device to be "seen" by my driver, said driver needs to be reinstalled. Note that this does not happen if the PCMCIA adapter has been previously installed on the system (prior to my driver's installation), as Windows seems to keep said adapter in its device manager, albeit in a "hidden" state. Any ideas? ----- Benoît Bousquet (e-mail address is invalid) Tag: create an event at ring0 level Tag: 40712

    - error including <ntstrsafe.h> I get the following error when I build: error C1083: Cannot open include file: 'ntstrsafe.h': No such file or directory eventhough I do this in my driver file: #define NTSTRSAFE_LIB #include "ntstrsafe.h" and this in my "sources" file: TARGETLIBS = $(DDK_LIB_PATH)\ntstrsafe.lib Shouldn't this be enought? (I have checked that the DDK_LIB_PATH evn. variable is correct and that ntrstrsafe.lib is in that directory!) Tag: create an event at ring0 level Tag: 40701

    - Is AVStream class backward compatible to stream class for DirectX filter? I would implement driver for streaming device. I want to know whether the user mode DirectX filter implementation is affected by the driver class. That is, if I have a software package which contains some user mode DirectX filter and the device driver using stream class, can I replace the device driver by using AVStream class without modifying DirectX filter?

    - Need help with printer driver for capturing printer statistics hi all Is it possible to install rendering plugins on currently installed windows printers. What I mean to say is suppose printers a,b and c have been installed on a users machine. Is it possible to insall a custom rendering plugin on all these printers so that the existing functionality isn't disturbed. Effectively I would like to insert my rendering plugin into the chain of rendering plugins if any installed by the existing printer driver installation. I am particularly intrested in the IPrintOemUni::ImageProcessing and IPrintOemUni::FilterGraphics methods. I donot want to modify any of the print data, I only want to collect some statistics like the RGB pixel count etc That said, any other alternative strategy to spy on print jobs is welcome. I am interested in collecting the RGB pixel count for every printjob Thanks/Sreejith Tag: create an event at ring0 level Tag: 40690

KeInitializeEvent is the call that I use in Win2000/Xp, don't know
if it is supported in Win98, MSDN lib doesn't indicate.
