    - Legacy driver "cannot find the device specified" Hi All - First my apologies I am not a driver developer, but I hope some of the experts on this group can help! I have an XP machine on which the Microsoft userdump utility fails to install. The problem appears to relate to userdump.sys, installed as a legacy kernel mode driver. This will not start, and on boot-up or attempting to start (via the service userdump.exe which depends on it) SCM logs "The system cannot find the device specified". sc query udmpdrvr shows it stopped with WIN32_EXIT_CODE 20, which I think means the same. During an attempt to start it, Regmon shows an enum\root subkey LEGACY_UDMPDRVR being created by Services.exe, but it is then promptly deleted again. Can anyone please suggest ways of troubleshooting this issue, or suggest what might be going wrong? Thanks in advance - Mike. Tag: how can i convert wide character to multibytes? Tag: 44515

    - [XP] disk class filter & FAT32 Hi, I recently wrote a disk class upper filter driver. It starts at boot time! The very strange problem is that it is somehow dependent on the file system of the host system. case 1: WinXP is on a NTFS partition -> no problems at all case 2: WinXP is on a FAT32 partition -> I get 0x0000007b meaning INACCESSIBLE_BOOT_DEVICE. Since the filter only acts on disk class devices it shouldn't depend on the filesystem, right? Any ideas about that? regards M.O. Tag: how can i convert wide character to multibytes? Tag: 44514

    - disk compression? guys, I want to understand how the transparent disk compression works, I already know it works as a compression layer between the OS and the cluster/sector access. but I am confused, even if a cluster or chunk or block can be shrunk into less than its original size, there will be unused parts and the end in such a unit. the compression would be effective only if those unused units are reutilized somehow, but how ? I don't get it. please help me out Tag: how can i convert wide character to multibytes? Tag: 44494

    - Dot Matrix Printers and XP I have an application which prints invoices to an Okidata ML 590 on XP. After the print job is complete, the printer doesn't advance the paper to the correct position of the next page I've printed a test page from the print server configuration and found the test page doesn't advance to the correct position. I've also found that MS Word and Notepad also do not advance correctly. The printer (when pressing the FF button) advances the page correctly The Okidata site doesn't offer a driver for XP and says the only driver available is in XP I've also found the above issue is happening when using a Panasonic impact printer Any ideas or suggestions Thanks for any help Tag: how can i convert wide character to multibytes?

    - [newbie] invalid pointer value in kernel mode Hi some newbie problem. I'm using a linked list in kernel mode and a loop to walk through it. Now, I need a statement that causes a break of the loop - in this case, an invalid pointer value test = head; //head is -guess what- head of the linked lis for(;test->Next != ??;test = test->Next //do somethin The thing I'm looking for is a replacement for ??. I've tried NULL, but this ends up in an immortal loop (I guess all bits in the pointer test->Next are set to 1). Is there a statement that reflects the 'default' value of a pointer, when it wasn't initialized at all Thank Sam Tag: how can i convert wide character to multibytes? Tag: 44473

    - inter driver communication ? hi how do you call one driver's functions from another ? I searched the archives but the threads i found talked only about communications among drivers lying on the same stack. If i have to route packets coming to the NIC to some other PCI device so that it can process them, how do i call that PCI device's driver's functions and pass them the packet data so that it can process them and then return them back and i can pass them over to the NIC. I am using the DDK's sample "NDIS passthru intermediate driver" for hooking the packets and now want to call the other PCI card's functions to process those packets before sending them over i dont know much about drivers. is there a way i can get the other driver's handle from the kernel and call its funcitons any help will be appreciated. and since i am a novice therefore details are welcome taj.

    - Help, why PCI bus master memory read fails, many retries? I have a PCI device that seems to be unable to read from main memory but only after a large amount of virtual memory has been freed up by an unrelated application. This is on Win XP. I'm new to Windows drivers so don't know all the terminology and have hunted google for this answer without success. The PCI device is controlled with a Jungo based WinDriver and peridically the PCI device reads a few words from main memory so it knows what to do. The driver when opened has used Jungo's WD_DMALock() call to lock the pages in physical memory. All seemed to run well for 6 months until a new big application that allocates a lots of memory came along. And it is only when that big application exits that the problem occurs. It seems like a virtual memory management thing is getting in the way. Anyway, the PCI bus analyzer shows that the PCI device tries a bunch of times (currently 127 retries) to read from main memory and eventually gives up when all reads timeout. So what is going on?

    - Newbie Q : TDI driver communicating with user app? Hi, I'm totally new at this, so please forgive the basic question. I am attempting to modify a TDI filter driver so that it communicates with a user mode application to do some processing of the data. Based on the application's response, the driver will change some of the data before forwarding on the rest as usual. It seems that I can share the data with the app by making DeviceIoControl() calls to pass in a buffer to the driver to fill in and then for the app to send its response after it has completed its analysis. An article, http://www.osronline.com/article.cfm?id=108, suggested using named events created by the app to control access to shared buffers, so I attempted to incorporate that. My problem is that the driver, while it's fetching the data, can't seem to wait on a named event. However, if I stick in a KeWaitForSingleObject() within the handler for the command sent by DeviceIoControl(), it seemed OK. Does this sound like the right approach? What am I missing? Thanks for any help. V Tag: how can i convert wide character to multibytes? Tag: 44433

    - linking ZwCreateSection prevents driver loading ?

    - CIS in common memroy Does Windows occasionally access CIS on other times then at start up (power-up)? I'm interrested in this because I'm thinking of loading CIS into my 1 KB SRAM during power-up, which is the only space on the card that is used by the PC card interface. And then remove the CIS, after Windows have read all it need, to make the space avalible for registeres that is needed for the cards original function. Needs all of the 1KB space. (The PC Card have the logic that supports this replace-idea, but those Windows/ PC Card standard support it?). This implies that the CIS have to be in common memory.

    - how to match usb vid/pid with mass storage drive letter in win98 Hi I would like to find the drive letter assigned to my usb mass storage device. In win2k/xp, I can use QueryDosDevice and the SPDRP_PHYSICAL_DEVICE_OBJECT_NAME registry property to find the drive letter. But in win98, I have encountered a few problems using the same method 1. QueryDosDevice always give me back the device name. e.g.: i use "c:" as input, the function will give me back "c:". Is it a normal behaviour in win98 2. I use umss as the driver of my device so I cannot find the volume interface of my device. So how can I get the SPDRP_PHYSICAL_DEVICE_OBJECT_NAME of my device in order to compare with the returned value from QueryDosDevice 3. I do not know whether I should also use this method in win98 or not. Is there anybody who have tried this I am just a newbie. Can anybody give me some hints?

    - Accessing floppy disks with 10 sectors per track Hi, I've got some old double-sided double density disks that are formatted with 10 sectors/track rather than the standard 9. Do anyone have any ideas how I could read/write these under 2000/XP? I noticed from looking at the DDK that flpydisk.sys doesn't support this layout. I was wondering whether it's possible to write some sort of simple filter driver to tell it about the extra sector per track? Just in case this is important, sector ids run 1 through 10, track numbers (in the sector headers) run 0-79 on side 0 and 128-207 on side 1. Actually, it would be really handy if I could get at the actual sector headers as well as the data... Regards, Jonathan Needle Tag: how can i convert wide character to multibytes? Tag: 44392

    - Question about system page table entries Hi reading about terminal server sizing I recognized the term "system page table entries" quite often. Unfortunaltey I understand the 4 GB virtual memory is devided into 2 GB users space (a private space for each process) and a 2 GB system space. Page table entries are used to map virtual memory addresses to physical ones. From my understanding, system page table entries are used to map the complete 2 GB system space to physical memory and normal PTEs describe the users space. I heard SPTEs are a limited resource and the OS is not able to use the complete 2 GB space due to this limitation If I'm wrong and SPTEs describe only portions of the system space, which portions are described? Why isn't it possible to use just PTEs I appreciate your help Stephan Tag: how can i convert wide character to multibytes? Tag: 44391

    - question about using VC6 with DDK Hello, i just bought Walter Oney's book on WDM drivers. so far it is really good, but i am just at page 100. at this moment i have 2 question: - in the introduction Walter says that he uses VC6 for programming and building device drivers, but i havent found am explanation so far that tells me how to set this up. is it enough to just change the compiler? and what am i supposed to enter for build target?is it enough to use the VC6 plugin or do i need to do more? - is it possible to use VC .NET 2003 instead of VC6? i still use both on my system, but i would rather move to VC .NET where possible. i am sorry if i ask questions that are answered in the book, but i have skimmed through it to see if they were, and did not find anything. i have not read the book completely, but wanted to compile an empty example to get a feel for it. rather than taking a finished example from the CD, i would build an empty driver myself so that when it is finished, i would really know what was in there. kind regards, Bruno.

    - Bluetooth HCRP credit flow Hi Folks, I am developing an HCRP firmware (Printer side HCRP profile) and testing it against the XP Bluetooth HCRP driver. I am successfully able to - have the XP host detect my device as a "HCRP Printer", - the L2CAP Control and Data channels getting created - a new printer also gets added to my "Printers and Fax" collection on the HCRP Host. Now When I try and print a document using this HCRP printer following happens: a. I get a CR_DataChannelCreditRequest on the L2CAP COntrol Channel (Printer side) to which I reply with a large number of credits (0x00 00 00 00 00 FF FF FF). b. I start recieving bytes on the L2CAP Data channel. c. After recieving 64KBytes, the Host application doesnt send any more packets. Neither any bytes on Data Channel, nor any more CR_DataChannelCreditRequest. However I recv. all the data for if the print data is less than 64K, my question is this 64K any magic number ? IMO I should be getting periodic requests for credits on the Printer side after the HCRP Host has exhausted all the credits, but no such thing happens. How has the HCRP driver in XP been implemented to handle this situation ? I have also tried sending some credtis (voluntarily) from the printer side to the Host using the CR_DataChannelCreditGrant after the 64K bytes of credit have been exhausted, but to no avail. help in any direction appreciated. thanks people for all your patience.

    - Bypass print processor Hi I have a customized print processor associated to a printer. That print processor copies the Spool files of jobs printed by users. In another application, users will take actual print outs with those spool files using the same printer. When they are actually printing, I should bypass printprocessor (Otherwise, it again copies the spool files). How to write RAW data directly to Port monitor/Printer, bypassing the print processor In my application I tried like this StartDocPrinter() StartpagePrinter() Read the spool file() WritePrinter(); // Tried printer name, Port name. Both are spooling the data.1 loop until end of file EndPagePrinter() EndDocPrinter() In the above approach, printprocessor is getting invoked. Also I tried different spooler properties like Print directly to printer. That too didn't work Is there another approach all together(My client does not want 2nd printer associated to another print processor) Thanks & Regards Kira Tag: how can i convert wide character to multibytes?

OID_GEN_MEDIA_CONNECT_STATUS also shows connected state. But wireless properties does not show that I am connected to the AP. DHCP also does not happen. Why is this happening? Ndis goes on trying to associate with the other APs in the list, with the same result in each case. What else do I need to do to inform NDIS that the card is associated? I tried doing the connect indicate as soon as I get the set SSID request, to eliminate any timing problems, but there is no difference. My driver ndis version is 4.0 - when I tried building as 5.1 the driver did not load. Tag: how can i convert wide character to multibytes? Tag: 44290

    - Serial smartcard reader in win95/98 caused process msgsrv stop Hello everyone: I am working on improving our serial smartcard reader driver performance in win95/98. The reader works well with all the PC/SC standard cards now. But when connect the reader to PC,it caused process msgsrv stop. After disconnect the reader, the process msgsrv works ok. I have tried do the test with SCM111 reader, it hasn't such problem. What's possible wrong with my driver then? Thanks for your attention and help!

    - [Q] dwIoControlCode of DeviceIoControl : IOCTL_NDIS_QUERY_GLOBAL_STATS vs. ? Dear all, I have a stupid question. I know the dwIoControlCode of DeviceIoControl is IOCTL_NDIS_QUERY_GLOBAL_STATS for getting a OID value. However, I do not know the dwIoControlCode for setting a OID. Please let me know what the dwIoControlCode for setting NDIS OID is. Thank you. //Daum Tag: how can i convert wide character to multibytes? Tag: 44275

    - Inside IoCompletion routine Hi I'm wondering if there are any restrictions of what functions can be called from IoCompletion routine When I'm trying to open text file from IoCompletion routine I've got "Blue screen" IoCompeletion routine works fine without this I'm using RtlInitUnicodeString(&usname, LOG_FILE) InitializeObjectAttributes(&oa, &usname, OBJ_CASE_INSENSITIVE, NULL, NULL) status = ZwCreateFile(&FileHandle, FILE_APPEND_DATA|GENERIC_READ|SYNCHRONIZE, &oa, &iostatus, NULL, FILE_ATTRIBUTE_NORMAL, 0, FILE_OPEN_IF, FILE_SYNCHRONOUS_IO_NONALERT, NULL ) The same code works fine when called from DriverEntry(...) or AddDevice(... thanks, da Tag: how can i convert wide character to multibytes?

    - "welcome to the found new hardware wizard" Hi All, i am trying to re-enumerate the devices on a system. If the user has uninstalled the device by going in the device manager it doesnt show up in SetUpAPIXXX calls. Anytime i re-enumerate the devices if any devices do not have drivers installed then the "welcome to the found new hardware wizard" comes up on WIN2k and WINXP. Is there any way to suppress this wizard or is there any way of enumeration so that i can see all the disabled present devices but dont invoke this wizard. Sunny.

I think

"Making UNICODE_STRING with wide characters in a buffer and convert to ANSICODE_STRIN
then, takes the buffer

is not a good way to do this

Would you help me?

You may not think it is a good way but it is the right way. Microsoft just
made a major effort to get rid of null terminate strings since they have
nasty buffer overflow problems, so what is your problem with this approach?
