    - 64-bit driver install I am trying to figure out why pre-installing our USB driver works a little differently on a 32-bit WinXP than on a 64-bit WinXP. The only difference is that after the install on the 64-bit system, when the device is plugged in, instead of popping up the "Found New Hardware" wizard to allow the user to complete installation, the installation silently quits, and the user has to go back to Device Manager to ask it to install the driver. The pre-install of the .inf logged a warning about the INF not containing a digital signature(same on both systems). Yes, our driver is unsigned. The policy on the computer is "Warn". The only error I see in setupapi.log is 1168 "Element not found". But this shows in the successful installation anyway, so I am assuming it has something to do with our driver being unsigned. We have a 64-bit version of the driver, and the required NTia64 decorated sections in the .inf file. Our application and install program are 32-bit. We use SetupCopyOEMInf() to pre-install the .inf file. The DDK says "Provide both 32-bit and 64-bit compilations of all kernel-mode drivers, device installation applications, device installers, class installers, and co-installers. " Does it have something to do with our install program being 32-bit? We aren't using UpdateDriverForPlugAndPlayDevices, and I don't see any other specific instructions on what problems a 32-bit install would cause. Any suggestions would be appreciated. The driver itself works fine, we just have this one little installation glitch. Thanks, Diane Tag: Multiple Monitor Tag: 34566

    - Implementing JPEG support in unidriver based rendering plug-in Does ICM have to be handled by the driver in order for it to be recognized as one supporting JPEG compressed images? DDK is somewhat vague on the issue. Also it appears that for unidriver you should rather hook Escape instead of QueryDeviceSupport (it never gets called?). However, when application calls ExtEscape with QUERYESCSUPPORT and CHECKJPEGFORMAT parameters, it always returns 0, while rendering plug-in never gets called. (Though if you do QUERYESCSUPPORT for something else, it will call Escape of plug-in.) The flGraphicsCaps2 has GCAPS2_JPEGSRC bits set and both QueryDeviceSupport and Escape are hooked. Am I missing something? ICM? Tag: Multiple Monitor Tag: 34542

    - NDIS 5.0 intermediate driver problems with Nortel's VPN Hi, I am having some difficulties to operate my NDIS 5.0 intermediate driver in conjunction with Nortel's Contivity VPN Client. I start with a Dell laptop with an on-board 3Com NIC running Windows XP SP1. The laptop is plugged into a docking station with an additional identical NIC. I install the Nortel VPN Client software and reboot my machine. When the system comes up I install my software which includes an intermediate NDIS driver. The installation seems normal and no error messages are displayed. However, after I restart Windows, I cannot access the network (ipconfig only sees the VPN virtual NIC). The above problem has not been observed on any hardware except the Dell laptop, nor has it been observed on the same laptop when the installation is performed outside the docking station. Also, if I reverse the installation order (i.e. 1st my software, then Nortel's VPN), everything seems fine! Can anyone suggest what's going on? Any input will be most appreciated.

    - Q : About WPA of WLAN - How to generate AES key material? Q : About WPA of WLAN - How to generate AES key material? Hello, everyone. I am developing a WLAN Ndis driver for WPA and use WinXP Wireless Client program as a WPA configuration. Currently, I¡¯m testing "AES" encryption facilities at "Adhoc" mode configuration. I know 32 bytes of key material should be generated from SHA1 algorithm defined at Wi-Fi. (Shane noticed me that. Thank you very much Shane) But i couldn't understand the appendix F of Wi-Fi specification, April 2003. I need more information to generate AES key material. The details are: 1) In 802.11i D3.0, an HMAC-SHA1 Test vectors shows that sha1 has 20 byte output, but we need 32 bytes output for key material. I couldn't find any explanation about that. 2) I couldn't know that where "digest" came from as an input parameter when the first call to hmac_sha1. See below. hmac_sha1( digest, ssidlength+4, //Where from digest? Did it come from SSID value? (unsigned char *)password, (int)strlen(password), digest1); 3) What's the value of A_SHA_DIGEST_LEN when the 2nd call to hmac_sha1? Is it 32? Where was it defined or explained? See below. hmac_sha1( digest1, A_SHA_DIGEST_LEN, (unsigned char *)password, (int)strlen(password), digest); Thank you. Tag: Multiple Monitor Tag: 34536

    - Usb v1.1, Iso URB callback frame number is out of sequence I have written an Usb v1.1 Isochronous driver implementation. The attached Usb device uses the Philips Isp1581 chip. For the most part it works fine. I am resubmitting/recycling 2 Urbs. Each Urb has a buffer length to contain 4 frames worth of data. The Iso Max Packet size is 1020 bytes so the Urb buffer is 4080 bytes. The Urbs are passed back to my driver from the bus driver at intervals of 4 frames per Urb. All frames are in sequence. Occasionally, a Urb comes back at an interval of 8 frames (i.e. some frames have been skipped). Later, a subsequent Urb callback occurs containing the missing frames. In other words, this Urb has a frame number less then the previous Urb. When this occurs, The frame order is out of sequence and the data stream becomes non-contiguous. Does anyone have any idea how this can happen? Rex Tag: Multiple Monitor Tag: 34535

    - IoGetDeviceObjectPointer getting STATUS_SHARING_VIOLATION? I'm using IoGetDeviceObjectPointer to open \??\PhysicalDrive0. This works fine, unless my application opens it before calling the driver. In which case I get STATUS_SHARING_VIOLATION (0xC0000043). I open it from my application using: CreateFile("\\\\.\\PhysicalDrive0", GENERIC_READ | GENERIC_WRITE, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL); From within my driver I open it using: IoGetDeviceObjectPointer(L"\\??\\PhysicalDrive0", FILE_READ_DATA, &fileObj, &deviceObj); Is this not allowed? I can call CreateFile multiple times from my application to open the device and that seems to work fine, but using IoGetDeviceObjectPointer doesn't work. Thanks, Josh Tag: Multiple Monitor Tag: 34529

    - MEDIATYPE_??? for grayscale images. I have googled heavily trying to find the appropriate mediatype and sub type for grayscale images. While I cannot find anything I would call definitive, I cannot believe that this has not been done before. Since there is no point in reinventing the wheel, I wonder if someone could point me in the right direction. The formats that need to be supported are: grayscale 8bpp, one byte per pixel grayscale 10bpp, two bytes per pixel, upper bits zero extended grayscale 12bpp, two bytes per pixel, upper bits zero extended (I can see the need for more bits in future cameras) I assume the major media type would be MEDIATYPE_Video. But the subtype?? I have seen a fourcc type Y800 (with apparent aliases Y8 and GRAY) that could work for the 8bbp. Should that idea be extended for 10 and 12 bits (Y010 and Y012 perhaps) or would another approach be better? MS seems to recommend creating new GUIDs which seems reasonable to me. I am hoping that there is a convention already in use (there must be a monochrome camera community out there using dshow right?) such that my device can fit in with any renderers that happen to support the existing formats.

    - How to find port resources used by hard drives? I need to find the i/o port and status port for each IDE hard drive connected to a system. So far I've been able to get these from the standard primary/secondary IDE controller by using the following method: 1. Open \??\PhysicalDriveX, where X is the drive number I'm intersted in. 2. Send it an IOCTL_SCSI_GET_ADDRESS 3. Open \Device\ScsiPortX, where X is the PortNumber returned by IOCTL_SCSI_GET_ADDRESS. 4. Send it IRP_MN_QUERY_DEVICE_RELATIONS with relation type of TargetDeviceRelation 5. Use IoGetDeviceProperty to send the DEVICE_OBJECT returned by #4 a DevicePropertyBootConfiguration query. 6. Walk through the CM_RESOURCE_LIST returned by #5 I can find the port resources for the drive. However, this doesn't work for a serial ATA drive for some reason. It works fine up to #5, but the IoGetDeviceProperty returns STATUS_OBJECT_NAME_NOT_FOUND (0xC0000034). So, is there a better way to get this information for each IDE drive? I've only been working with Windows device drivers for the past 3 weeks, so if anything doesn't sound right, it probably isn't. Let me know if I can provide more clarification to the question.

    - Replacing signed drivers Hello All, I have a doubt regarding one signed driver replacing another signed driver. My situation is as follows: [1] I have a set of drivers (version 1.0) which install a given USB device. These drivers were successfully WHQL tested. [2] Now i have a new set of drivers (version 2.0) for the same device. These drivers will also be tested with WHQL tool for certification. It can be noted that apart from driver versions there is nothing different between the 1.0 and 2.0 INF files. At this point i have a few scenarios which need clarification from experts: =========================================================================== 1) If user has installed version 1.0 drivers first and later tries to install 2.0 drivers (signed ofcourse) then will the 2.0 drivers replace the existing 1.0 drivers? 2) If user has installed version 2.0 drivers (signed) first and later tries to install 1.0 drivers, then when the device is connected which of the INFs will be considered for installation? 1.0 or 2.0? Is INF-matching based on newer of older versions of the INFs? NOTE: Installation in the above scenarios are done programatically through SetupXXXX functions. Any pointers on this will be highly appreciated. Hari Tag: Multiple Monitor Tag: 34507

    - Receiving DBT_DEVNODES_CHANGED from a Windows service I have a Windows service that needs to be notified when a particular device has been enabled or disabled. When either of those actions happen, I have noticed that Windows broadcasts WM_DEVICECHANGE with a wParam of DBT_DEVNODES_CHANGED. Since services don't receive Windows messages, I understand that I should be using RegisterDeviceNotification along with HandlerEx to receive device notifications. However, the documentation for RegisterDeviceNotification says that it only supports the DBT_DEVICEARRIVAL and DBT_DEVICEREMOVECOMPLETE events, which doesn't help me. So my primary question is: How can my service be notified when a device has been disabled or enabled? Related questions: 1. I've heard that some people create a hidden window to receive broadcast messages in cases like this. This sounds kind of weird to me. What are the possible problems with this approach? 2. Also, can what I'm asking about be done from a Windows service with WMI? If so, is there any sample code of WMI being used for this purpose (in a service or otherwise)?

    - New at this... need direction Hello, I have been assigned to write a device driver for 2000 & XP. I am a seasoned developer with an M.S. in C.S. I have zero experiece in writing device drivers. I have downloaded the DDK. Are there any web sites by MVP's that help? Is there a FAQ? Books? I was told that I have to have a development tool, that Visual Studio 6 will not do this. Is this correct? Help me get started so that I can understand the "vocabulary" of device drivers and better understand the posts in this news group and allow me to ask precise and informed questions. Thank you, Gil Tag: Multiple Monitor Tag: 34469

    - Example class installer for Win98 I've been tasked with writing a class installer for a Win98 driver. Unfortunately, there seems to be a conspiracy of silence on this subject. I have Googled until my mouse cramped. I have searched the Knowledge Base. I have searched the Technical Resources. I have read books (which have said there are no known samples and/or that the task is "hard" and will not be addressed). I simply cannot believe that there is not and never has been documentation on how to write a Windows 98 class installer DLL. After all, such installers do, in fact, exist! I would greatly appreciate any guidance that any of you may have on this topic. Feel free to email me directly, and I solemnly promise not to break the sacred layer of secrecy by telling anyone else of your help. Many thanks in advance. -- Roy M.

    - need help resolving crash cause hi all I have been working on a driver for winXP that emulates a harddisk, based on hardware that connects to the system through some General Purpose IO pins. therefore it is not PnP Enumerable and is "manually" root enumerated using IoReportDetectedDevice(). the DriverEntry and AddDevice routine load fine, and I can use it as the current drive in the CMD utility, read, write and copy from it, until it reports the following correspondence with the system: --------8<------------8<----------- CREATE/CLOSE function issued. major=IRP_MJ_CREATE, minor=0 RemoveLock acquired with tag 80F33330 Unrecognized IOCTL 4D0008h about to release RemoveLock with tag 80F33330 CREATE/CLOSE function issued. major=IRP_MJ_CLOSE, minor=0 CREATE/CLOSE function issued. major=IRP_MJ_CREATE, minor=0 RemoveLock acquired with tag 80F33330 Unrecognized IOCTL 4D0008h about to release RemoveLock with tag 80F33330 CREATE/CLOSE function issued. major=IRP_MJ_CLOSE, minor=0 CREATE/CLOSE function issued. major=IRP_MJ_CREATE, minor=0 RemoveLock acquired with tag 80F33330 Unrecognized IOCTL 4D0008h about to release RemoveLock with tag 80F33330 CREATE/CLOSE function issued. major=IRP_MJ_CLOSE, minor=0 ------------8<-----------8<-------------------- which is followed by the shutdown of all the harddrive- type drivers in the system. my driver is still operable until other services need the original harddrives and start crashing the system. what is the meaning of the above IOCTLs? I can't find this number in any .h file. it must be the result of some sinister #define. I tried to Install the checked version I downloaded from MSDN, but so far the installation either gets stuck in the file copying phaze or stops after not finding the license agreement file (I would appreciate help on this one also). thanks in advance, iddan Tag: Multiple Monitor Tag: 34457

    - How to install genprint.dll?? Hi~, I'm newbie in ms-windows and VC programming. :) I should develop NT service program that prohibit user's printing any documents. I tested SetPrinter() and I found a problem. Using SetPrinter() can't control network printer that attached in other machine. ('Access denied' error is displayed when calling OpenPrinter() using DesiredAccess set to PRINTER_ALL_ACCESS) So I should find another method. I want to block all printers installed in local machine(local printer and network printer). But for the network shared printer, another computer should can print using this network shared printer. (Only a computer that my program is installed should be influenced by my program) Q.1 Can I hook printing event or job or print spooler? (I think GetJob() also can't filter user's printing job...) I posted this question to many newsgroups or forums but I didn't get suitable answer(may be impossible??...) Now, I'm testing Customized Print Processor using genprint.dll from ddk. I built and copy it to C:\WINNT\system32\spool\drivers\w32x86. And I made its installation program. int main() { ... nResult = GetPrintProcessorDirectory(...,processorPath,...); _tcscat(processorPath, _T("\\genprint.dll")); nResult = AddPrintProcessor( NULL, // server name NULL, // environment name processorPath,//processorPath, // path "My Processor" // ----> what string should I use?? ); } It returns error string("The specified module could not be found."). Q.2 Which string should I use in pPrintProcessorName field? and processorPath string(C:\WINNT\system32\spool\drivers\w32x86\genprint.dll) is right? Q.3 If I success AddPrintProcessor(), how can I change Print Processor to "My Processor" from "WinPrint" of existing printer? Q.4 I can't change Print Processor property of network printer manually(Print Processor button is disabled). That means, using customized print processor also can't control printing network printer? Thanks in advance. And I hope you can understand my poor english :) Tag: Multiple Monitor Tag: 34450

    - PCI sample driver for 2K Hi, Is there any place where I can find a sample PCI device driver for Windows 2000. Or can anybody mail me the skeletal driver of the PCI driver. I am a newbie and have to write a device driver for a PCI based device on win 2k. Can anyone tell me if it is possible to have 2 drivers loaded for the same device? One more question... Can a user application directly talk to this PCI device without any device driver in between? Somebody was saying something about IOCTLs... Is that the right lead? Please help!

    - handling multiple interrupts?? hello sir, am working on developing wdm driver for a cpci carrier board.four independent I/O modules can be mounted on a carrier.so in a memory map there are four seperate memory space for each i/o module. usually in a application i call createevent & send it to driver inturn driver calls ObReferenceObjectByHandle - Registers Event in kernal mode. on interrupt driver calls KeSetEvent to notify the app the event. there is a single driver & four different applications comunicating with driver. now the question is how do i handle interrupts?? should each application call create event & send to driver? & how driver notify the different applications correctly when multiple interrupts are generated?? how to hold each application handle & notify to it?

    - How to define the USB vendor specific command in Language monitor Hello, I'm trying to use IOCTL_USBPRINT_VENDOR_GET_COMMAND and IOCTL_USBPRINT_VENDOR_SET_COMMAND to communicate with UsbPrint in my language monitor but I have no idea how I can set and read the internal irp packet (Irp->AssociatedIrp.SystemBuffer...) Is there any way to use these command in GetPrinterDataFromPort function of language monitor that call Port monitor's GetPrinterDataFromPort with parameters (inbuffer,inbufferSize, outbuffer, outbufferSize).. Can I just assume that inbuffer/outBuffer as Irp's Systembuffer? Thanks Jeth Tag: Multiple Monitor Tag: 34437

    - Video Card Drivers - Signed Drivers -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello,c 1. Is there any place where I can find out (before purchasing) whether or not a Video Card vendor uses signed drivers? 2. Is there some way I can determine this from examining updated drivers---without actually having the hardware to attempt an installation? This information seems to be lacking from catalog entries and from the specifications on the packaging. Background: I have a Creative GeForce2 Blaster 2 video card. It is about 2 years old. I am running Windows 2000 with all patches. I like to set Windows to reject attempts to install an unsigned driver. I consider this to be a nice, simple step to increase security. Unfortunately, I cannot do this because of my video card.

    - USB block size I encountered in my Language Monitor a major difference in data handling when I use a parallel port vs . a USB port to print to my printer. The parallel IO is transferring data in blocks of 64K and the USB has only a block size of 4K. This caused some unexpected behavior at the end of a print job so I am looking for a way to change the block size for the USB port to reflect the same size as the parallel. Does anybody know if I can change the block size when opening the port in the Language Monitor? What about the write and read timeouts, can they be changed down in the Language Monitor as well or is this to be done in an application? Help with these questions is much appreciated. /Manfred Tag: Multiple Monitor Tag: 34409

    - Get network adapter disable/enable status thru wmi Hi All, Is it possible to determine thru WMI whether a network interface is either enabled or disabled. Devcon sample in winddk displays this status but i would like to know if the same can be obtained from WMI. "Win32_NetworkAdapter" class has two attributes string Status; uint16 StatusInfo; when i see these values for network interface thru wbemtest.exe values are null. According to the description of "StatusInfo" this should be able to give me enabled or disabled status. Is there any other way thru WMI to detect enabled/disable status. Thanxs & Regards, Vijay Chegu PS: Plz note i dont want network connection status, i want enable/disable status which can be altered in "network and dialup connections" window through right click. //vijaycheguwmienabledisable Tag: Multiple Monitor Tag: 34405

    - read Flashdisc on Windows PC (newbie) I have a USB FlashReader from Quatech, PCD-U, which supports a 16Mb PCMCIA PC Card from SanDisk. The cards that I need to read have NOT been written as files on discs, but in what I suppose to be a "regular memory format". The software from Quatech seems to only support "disc formatted" PC cards, although I am by no means sure of that. I am running on a Windows XP machine and am also the proud possessor of a MSDN Universal subscription that seems to include everything from Microsoft that I would ever need. My question is - what do I do next? I cannot seem to find any examples or sample code for reading a flash memory card via USB with whatever handler/driver combo is necessary. Any pointers would be greatly appreciated. TIA Bill Tag: Multiple Monitor Tag: 34404

What steps need to be taken to make multiple monitors appear? Specifically
what registry keys (if any), what functionality in either the Video Miniport
or Display Driver?

In HwVidGetVideoChildDescriptor, what should pChildDescriptor contain if the
monitor is a non DDC monitor? Is this the only way windows knows about a
monitor? Where does the pUID come from? (Who assigns it or is it basically
random?)

Thanks
