    - Getting an NDIS driver to send packets back up the stack Hi, Since my LSP cant see "all" tcp or udp traffic, I wrote an NDIS intermediate driver to send packets that my loop back hasnt seen back up the stack to a different port where I have a listener application that will re attempt to send that data using winsock Using a sniffer (ethereal and etherpeek) im able to verify that I can modify the packets correctly and change the destination IP addr and port to be the sending machine and some other port where my listener app is running However, my listener app never sees a socket connection Is what im trying to do possible?

    - 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: WLAN driver for Windows CE.NET - which tool? 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: WLAN driver for Windows CE.NET - which tool? 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: WLAN driver for Windows CE.NET - which tool? 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.

    - 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: WLAN driver for Windows CE.NET - which tool? Tag: 34507

    - isn't it a sample of virtual port? there is a sample PORTIO in win2000 ddk, isn't it a demo of virtual port? the sample is also included in softice driver suite 3.0. I use win2k DDK to build the PORTIO sample in DDK successfully. But something is wrong when I use the gpdread and gpdwrite to test the driver. I use command line "GpdWrite -b 1 2" to write the number 2 to assigned 'base port address + 1', and then "GpdRead -b 1 "to read out. But the number read out is always 0xFF. I also tested writing a number every 1000 milliseconds and reading every 600 millisecond, but the read-out number kept 0xFF. what does the sample mean? could you tell me why? thanks Tag: WLAN driver for Windows CE.NET - which tool?

    - 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)?

    - 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.

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: WLAN driver for Windows CE.NET - which tool?

    - 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: WLAN driver for Windows CE.NET - which tool? Tag: 34450

    - 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?

    - 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: WLAN driver for Windows CE.NET - which tool? Tag: 34409

"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.

    - 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: WLAN driver for Windows CE.NET - which tool? Tag: 34404

    - ksproxy plugin design issues I am considering design choices about controlling custom aspects of a USB2 camera. This camera driver is based on usbcamd2 and is currently proxied by ksproxy. The intent is to create ksproxy plug-ins to result in the following: 1) 1 or more property pages such that amcap, graphedit or the like can set these custom properties and 2) A way to programmatically set these same properties from a dshow filter via some method. Regarding the programmatic control of the filter: a) Is it better to create a custom interface so that from the client filter I can QI the base capture filter or is it better to QI the base capture filter for IKsPropertySet and set the properties directly? The first choice would seem better as it would introduce a layer of indirection such that there would not be such a tight coupling between the minidriver and its usermode clients. b) If I were to use the custom interface, would it be better to implement it via IKsPropertySet or via KsGetObjectHandle and issue IOCTL_KS_PROPERTY? They seem identical. Regarding ksproxy plugins in general. What is the mechinism linking the extension COM objects to ksproxy? The examples I have seen all seem to have an exact correspondence between one propertyset GUID in the minidriver with one custom interface and one property page. Is this always the case? Are the following alternatives possible: 1) A custom interface but with no associated property set? 2) Multiple custom property pages associated with a single property set? 3) A single propertyset with any number of interfaces and property pages hung off it? These questions reflect uncertainty about my ability to implement my current thinking which is: 1) Add a one or more propertyset GUIDs to the minidriver to implement the custom aspects of the camera. 2) Have a single custom COM interface in usermode to permit programatic access to those aspects. 3) Have one or more property pages to permit amcap etc to access to aspects. These property sheets would be implemented by using the custom inteface. Regards, Tom Udale Tag: WLAN driver for Windows CE.NET - which tool? Tag: 34403

    - Device could not start. I have a PCI driver for our custom I/O board. I generated the device driver with Walter's wizard. I modified the Toaster class installer for our device. I used a combination of the DDK inf generator and existing inf files. It looks like the driver worked just fine for a couple of months. Now, when I have one PCI card in the system, the device manager reports: This device cannot start. (Code 10) I can power down the machine, add a second card to the same bus segment, and both cards work fine when I power the system on. Where should I start to look?

My problem is, when I set the port to FILE: It seems that the value of pPrinterName is always the default printer(not the currently selected printer), It works fine when set to other ports like LPT1.

    - Interrupts in PCMCIA device driver Hi, I have been struggling with this problem for some time, so any help from someone who has written a PCMCIA device driver would be greatly appreciated! I have written a working Win2K device driver for a PCI device, and am now writing a device driver for the PCMCIA version of the device (some code included below). My driver does not receive interrupts although the call to IoConnectInterrupt() succeeds. I have gone through the PSCR smartcard device driver code in the DDK samples. I am also familiar with the DisabeISAToPCIRouting registry setting - didn't make a difference in my case. Is there something different one needs to do to receive interrupts in a PCMCIA device driver as compared to a PCI device driver?

    - a question about win2000 ddk PORTIO sample!!!!!! I use win2k DDK to build the PORTIO sample in DDK successfully. But something is wrong when I use the gpdread and gpdwrite to test the driver. I use command line "GpdWrite -b 1 2" to write the number 2 to assigned 'base port address + 1', and then "GpdRead -b 1 "to read out. But the number read out is always 0xFF. I also tested writing a number every 1000 milliseconds and reading every 600 millisecond, but the read-out number kept 0xFF. what does the sample mean? could you tell me why? Softice driver suite(driverworks) contains similar sample, things are same. ____________________________________________________________________________ _________________________ Test OS: win2000 server Develop Environment: win2k ddk, visual studio 6.0 sp5 Tag: WLAN driver for Windows CE.NET - which tool?

Hi,

I need to write a WLAN driver for Windows CE.NET (Pocket PC 2003). Can I
use Embedded C++ 4 for this task? Or must I used Platform Builder?

And what is the best way to debug such a driver (functions names to use)?

Thank you for your help in advance

/Marco
