    - 98 ndis driver installer/uninstaller I want to install/uninstall my 98 ndis driver. Is there installer code somewhere to do this? I have been reading on this,what I have figured everywhere on the internet is that it is diffcult to write the install/uninstall for 98. I have not got any explanation anwhere on how to do it. Any pointers will be great as I have been beating on this for a while. regards /n Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 64068

    - Checked build Hi All, In MSDN, it is said that we require checked build version of operating system to test and debug the driver. By making changes in boot.ini(/debug) i was able to boot the system in checked buid(windows XP). But i found no difference between checked and release build as both of them takes same time to load. But in MSDN it is said that checked build will take long time to boot as compared to release build. does it mean that checked build can not be made just by chaning the boot.ini and i need to install the checked build operating system?If so,how do i install the checed build? As i did not find the checked build OS(XP) in the opeating system installation CDs. Would of great help if anyone could guide me how to proceed. Thanks, Senthil Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 64050

    - Setting Driver Signing policy programatically Hi Ive read through the other posts and MS KB articles related to the setting of the driver signing policy. I cant determine if there is any way of setting this policy as we require. We have a large number of PCs (with no KB and no monitor) in remote, often non-networked environments. All installations at the sites must be unattended (bar insertion of a CD and pressing a proprietry interface button). These machines have a large range of periphial devices attached. Some of the devices are proprietary (and have signed drivers), others are from 3rd parties (and are both signed and unsigned). Historically we have installed all the SW on these machines from scratch each time we need to install anything (even a single msi). We have been able to do this by setting the driver signing policy in either unattend.txt (for standard installs) or sysprep.inf (for sysprep'd drive images). We are now in an XP Pro SP2 environment and have a need to (occasionally) install unsigned drivers after an initial installation has been completed. This can occur days or months after the initial deployment. For example, a new device is plugged into the unit and we need to install the SW / drivers for just that device. We were previously able to set the driver signing policy using the regsitry or rather we used SECEDIT and GPUPATE. As the machines are often not on a domain (or even networked) setting the domain policy is not an option; we need to set it locally. The customers who own the units are not prepared to have driver signing permanently switched off. If SECEDIT or GPUPDATE are used now (to either set the policy to "ignore" or to "block", then we get the error logged in setupapi.log (as described in 298503). "Permachine codesigning policy settings appear to have been tampered with. Error 13. The Data is invalid" Default of 1 restored to policy. This appears to indicate that we cant set the policy to "block" or "ignore" it will always go to "warn" if you try to programatically set it. Whilst I understand the reasons for tightening up on this setting we have a definite need to bypass this standard security for our business. For new devices and our own devices we now insist on signed drivers. We are still left (for now) with many legacy devices with unsigned drivers. The only solution I have just now is to spy for the warning windows and fire keypresses at the dialogs. Obviously this is less than ideal. Any help or comments appreciated.

    - Programming style... originated in the java corner, i have some difficulties to adapt the programming style used in the platform sdk and the ddk. therefore i'd like to know what you think about the way i handled some things. 1) device interface GUIDs not defined in a global header: i tried to find the GUID of disc type devices which are part of the mass storage device group. because i didn't find any, i looked up the GUID value stored in my registry and defined it in my app. is this a bad habit or can i assume that this GUID never changes in further versions of ms win? 2) error checking: SetupDiGetClassDevs and many other functions return a specific value if they fail. so should i check for failure although such case is impossible? e.g. SetupDiGetClassDevs with GUID_DEVINTERFACE_VOLUME should never fail. i ask because useless failure checks make the code unreadable.

    - Renaming a file The FILE_RENAME_INFORMATION structure has a RootDirectory field that may be non-NULL RootDirectory If the file is not being moved to a different directory, or if the FileName member contains the full pathname, this member is NULL. Otherwise, it is a handle for the root directory under which the file will reside after it is renamed. However, my testing so far has failed to create a non-NULL RootDirectory. I'd like to test my code that will handle this case, but I've not been able to create one . On NTFS file systems: Moving files between Directories with DOS does not do it. Moving files with Explorer does not do this. Rename from DOS does not support moving files between Directorys. Can anyone tell me how to cause this to happen ? -- Gak - Finecats Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 64032

    - Keyboard extension Hi. Some month ago I bought a keyboard with a function button. Product: Luminous III Manufacturere: Sharkoon in Germany Please look at: http://www.sharkoon.com/enghtml/input.htm#key3 When I press the new function button "Fn" together with F11 the keyboard is locked so nobody can use it until i unlock it with the same keys. Using the media player i can increase and decrease volume using FN and F9 / F10. What i now like to do is writing a new driver / an extension so i can decide what to do when a shortcut like the two obove is pressed. The reason why i want to do this is, that there's no existing driver i know i can use. I read some articles in the MSDN but i need some examples.

    - Formatted ramdisk Friday, May 27, 2005 Hi, I have modified the ramdisk sample driver to map a reserved memory (Booit.ini /burmemory=128). I also saved a NTFS formatted disk image file that I load during the initialization of my driver so I do not have to format the 128 MB ramdisk every time Windows boots. This works fine on Windows NT, 2000, 2000 SP1,2,3. When I installed the driver in Windows 2000 SP4, Windows prompts me to format the disk even after my driver loaded the formatted disk image. I can format the ramdisk (NTFS) successfully. However I do not want to format the ramdisk manually after every boot. Why Windows 2000 SP4 does not recognize that the disk is already formatted? Is there a way to format the disk NTFS in the driver Thanks, Daniel Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 63980

    - How to make sure a Service starts BEFORE a user logs on? Hi: I have a regular Windows Service program (not a kernel driver) which must start BEFORE a user logs into his machine (XP or W2K). It works most of the time, but sometimes, I noticed that it started AFTER I log on the machine; especially if I logged in the machine fast right after a reboot. Is there a way in the service program, I can do something to make sure that, after reboot, the service starts before a user logs in the machine (no matter how fast the user is trying to complete his logon process)?

    - How to enumerate USB Mass Storage devices? hello. i'm working on a hobby project for my own mp3 (usb mass storage) player and try to enumerate all usb mass storage devices currently connected to my computer. i've been working on this quite a while because i can't get through the msdn efficiently enough. i planned to identify my player like this: 1) enumerate all disks (by SetupDiEnumDeviceInterfaces in conjunction with guid GUID_DEVINTERFACE_DISK) 2) find out those who are mass storage devices (IOCTL_STORAGE_GET_MEDIA_TYPES_EX) 3) get each mass storage device's partition info 4) get a handle to the volume i chose the method above because i wanted to avoid a low level enumeration through the usb hubs. now i'm stuck with step 2 because i don't know how to find out the correct buffer size, needed by DeviceIoControl for the IOCTL_STORAGE_GET_MEDIA_TYPES_EX flag. the documentation didn't explain a proper use any further. so i wonder if any veteran can give me a hint, how to find out the buffer size. thanks. wan-hi Tag: AVStream driver performs differently under WinXP and Win2K.

    - Serious problem with IO manager and device removal Hi All Scenario: i)PnP NIC PcCard USB driver with an IO manager interface created with NdisMRegisterDevice(). ii)Application opens device with CreateFile() and gets a valid handle. iii) Stop NIC driver with Safely Remove Hardware. (Driver Halt function gets called and devext is freed) iv) Application calls DeviceIoControl() on the STILL VALID HANDLE. v) NIC driver image stil in memory, so IOCTL handler called which refgerences the now invalid devext. vi) CRASH. Now, to quote the DDK: "Note that, if a handle to the device object created with NdisMRegisterDevice is open, the driver that created the device object cannot be unloaded." Oh yeah, even NdisMDeregisterDevice() returns 0 if an application still has the handle open. And further: "Before opening a handle to the device object, a user-mode application should therefore register for device event notification, specifying GUID_NDIS_LAN_CLASS as the interface class GUID. On receiving a DBT_DEVICEQUERYREMOVE device event for the device object, the application should close the handle" So it is up to the good behaviour of an application to controlll wether the kernel crashes or not. Hmmm not a very good idea. I suggest the IO manager returns INVALID_HANDLE_VALUE if the device got unloaded and an app calls an IO manager function on it.

    - Trying to get an IM filter driver to bind to my IM MUX driver at install time Hi, I've got an NDIS IM MUX driver, which is based on the MUX sample in the W2k3 DDK. I'm trying to get an IM filter driver to bind to this, at *install time*. This filter driver is bound to the physical miniport before install (along with TCPIP, MS Client, File & Printer sharing). I've built the MUX notifyob with "DISABLE_PROTOCOLS_TO_PHYSICAL" defined, so ideally, i would expect that after the install, all the protocols that were bound to the physical NIC should now be bound to the MUX miniport. Unfortunately, the filter driver is not bound to it (incidentally, neither is the nlbs driver). I can bind the filter driver after the install, manually from the UI, by checking the box on the MUX miniport, so there isnt anything in the NDIS upperRange or lowerRange to prevent the binding from happening. I've stepped through the notifyobject in the debugger (from breakpoints in SysQueryBindingPath, and NotifyBindingPath) to see if the notifyob ever even got the binding paths with the filter driver in it. I didnt see any. The filter driver's protocol inf has the following interesting lines: 1. [ndi] Characteristics = 0x4490 ; NCF_NDIS_PROTOCOL | NCF_HAS_UI | NCF_FILTER | NCF_NO_SERVICE 2. [AddReg] HKR, Ndi, FilterClass, , failover HKR, Ndi\Interfaces, UpperRange, , noupper HKR, Ndi\Interfaces, LowerRange, , nolower HKR, Ndi\Interfaces, FilterMediaTypes, , "ethernet, nolower" Why isnt the filter drivers binding paths showing up in the notifyob methods ? Alternatively, is there any other way to programmatically bind the filter driver to the MUX driver ? (This is what i really want to achieve) Thanks, Gaurav Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 63920

    - Printer driver woes I'm using the bitmap driver sample from the LDK, and am running into a few problems. All I want to do is take the individual scan lines and pass them to an existing DLL that then does some processing. I can't seem to get the FilterGraphics method to get called. I'm return S_OK in the GetImplementedMethod, but no joy. Any hints on how to get that method called would be most appreciated. Since I can't get FilterGraphics working, I've been using ImageProcessing. I've set the PinsPerPhysPass and PinsPerLogPass commands in the GPD to 1, 8, 16 and several other variations, but I always get the same pSrcBitmap sizes when ImageProcessing is called.

    - DrvTextOut/DrvSendPage overlap Hi, I have written a monolithic printer driver. There is a problem when using MS-Office applications and printing with the my driver. My driver defines fonts that are resident in the printer. Most of the time, the driver works fine using MS-Word and selecting the printer fonts. However, occasionally, the page is terminated too soon. I have narrowed it down to where my DrvTextOut is interrupted (has not hit the return statement yet) by a call to my DrvSendPage (same PDev too). This seems to happen totally random. How can this happen? What should my driver do in this case? It seems like a bug with MS-Office, but I've never heard of it. Any ideas? Please? I'm getting deperate.

    - How do I determine modem type? Hi, If I'm looking at modem entries in the registry (class "Modem"), how can I determine the modem's physical connection to the system? For example, how can I tell if a specific modem is connected through PCI, USB, IR, Bluetooth, etc.? I noticed that the "MatchingDeviceId" value (SPDRP_HARDWAREID) usually has the correct type in it, but a few modems seem to be misleading. For example, I have a PCMCIA modem that seems to think its a USB device (apparently it implements a USB hub inside the card, but its not available externally). Is there some other way to determine the physical connection type? Thanks, Ed. Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 63885

    - USB Video Capture frame rate drop after Standby/Wake-up cycle Our USB Video Capture device running on XP on USB 2.0 runs at 30 fps. However, if we put the system into Standby mode while capturing a video (either capturing to file or simple video preview) then when the system awakes the video capture resumes but at a frame rate which now fluctuates around 24fps and goes as low as as 22 fps. It is visibly slower - not just a quirk in frame-rate reporting. This reduction in frame rate is not cumulative. i.e. if we repeatedly go into Standby mode and reawaken it remains at around 24fps. The framerate can be is restored to 30fps by simply stopping and restarting the video capture application. The problem does not occur if we attach our device on a USB 1.1 port; the framerate then remains constant through Standby/Wake-up cycles. We have tried to test this on other vendor's USB video capture devices to determine if it is a problem in our drivers but to date have not yet found one that can survive running an application through a Standby/Wake-up cycle without other, far more serious problems. Any assistance, or redirection to a more appropriate forum would be appreciated. Steve Thorpe Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 63884

    - user unable to print on windows 2000 cluster via port monitor. Hi I have written a cluster aware port monitor. It works fine in a normal environment. BUT when it is used on a Windows 2000 cluster, only users with Administrator rights can print!! Normal users fail to print..... Looking at my debug it seams that the monitor is failing on reading the cluster registry when the 'normal' user is attempting to print. Now I thought this was left to spooler /portmonitor, not to the user permissions. What I am asking is :- 1. Have I made a mistake in the configuration of the culster? with user permissions etc. or 2. Have I missed something in the port monitor its self? I have been trawling through the msdn documentation but have come up with nothing. Any tips would be welcome as its driving me mad.

    - AVStream : Remote controller (IR) Dear All, I am developing an AVStream device driver for an MPEG2 USB box. Now I want to implement the remote controller (IR) function. But I don't know what kind of device drivers (HID, IrDA NDIS and etc) should I implement? Where could I get remote controller (IR) sample driver codes? Any comments are very appreciated. Thanks, Edward Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 63836

    - Does exist this file on disk ? Is possible to verify in kernel mode if some file on disk exist without calling InitializeObjectAttributes() and ZwCreateFile() and controlling result status ? Does exist some method for enumeration files in directory without using ZwCreateFile() ? Peter Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 63835

    - question about still image capture device definition. Hi, We are developing usb2.0 camera. Now, i have some question want to confirm: first, If my usb camera's firmware writted according to Still image Capture device class and i want to capture an image from WIATEST or TWAIN application, what should i do in PC side? Should I writte user mode driver or some dll linking to application? second, If my device is standard still image capture and i want to provide a set of API to customer, what document should i refer?

    - keyboard filter driver Hi, Currently iam doing a keyboard filter driver based on kbfiltr example from ddk. My objectives are to 1. Insert multiple keystrokes from a single key press. For example, when user press <a> i must send it as <SHIFT><F1> in the same context of <a>. 2. Drop and remap multiple keystrokes. For example,when user press <ALT><F2> I must send it as <b> In my previous post,Mr.Doron suggested me the following for my 1 objective. >>>>>>>>>>>>>>>>>>>>>>>Doron's post>>>>>>>>>>>>>>>>>>>> >> if this is with in the context of <a> being reported to your own callback, >> just declare a KEYBOARD_INPUT_DATA array on the stack, initialize it, then >> call the upper service callback with the new keystrokes, then finally report >> <a> using the caller's buffer. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> I tried to execute what Doron told,and in the usermode application trace, iam getting <SHIFT><F1><F1><F1><F1><F1><F1>...... where <F1> goes infinite.

    - Is anyone familiar with the sonydcam.sys sample? Hi, I have a 1394 camera that is IIDC (DCAM) compliant. I would like to connect this camera to a DirectShow based viewer, but the camera does not have a WDM driver. Apparently, the Windows DDK has a sample called 'sonydcam.sys', which I believe is a WDM Stream Class driver. Unfortunately, when I tried connecting the camera using the associated 'image.inf' file it did not work. Obviously, I'm new at this and would like to ask the following questions: Questions: 1. Is the sonydcam.sys file a WDM Stream Class driver for DCAM cameras? 2. If it is a WDM driver, can I modify the image.inf file in some way so that it would recognize my camera as 'Generic'? 3. To view the camera with a DirectShow app, do I need more than the sonydcam.sys file? Thanks for any help. RickL Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 63822

    - Filter Hook Driver and NAT I have written a application based on the Windows 2000 Filter Hook Driver. Basically the application was designed to run on a Windows 2000 server with two Network interfaces. It monitors traffic between the two interfaces and enforces security, performs proxy redirection, etc. When the Windows 2000 Server is configured for routing mode and both interfaces have real address subnets (in other words Network Address Translation (NAT) and Internet Connection Firewall (ICF) are not enabled), the hook correctly works and our application receives the packets (header and payload). However, when NAT or ICF is enabled (the network we are checking security on does not have real addresses) the Packet pointer (payload) passed to us is NULL. Therefore we can not look at the rest of the packet to make a determination of what we should do. See this link for the call back function description (parameter two is the one that we are not getting): http://msdn.microsoft.com/library/en-us/network/hh/network/fltrhook_cb402c5c-f5db-498b-8db6-c2994bbf7870.xml.asp Why does the behavior of the Filter Hook Driver difer betwen NAT and routing mode? I would think the behavior should be the same regardless. Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 63808

    - Irp->IoStatus.Status vs return value? Hi All, What is the difference between setting Irp->IoStatus.Status and the Dipatch function return value? I have a little trouble seeing the difference between those, as they seem to fulfil the same functionality, ie telling the system about the status of the Irp. kind regards, Bruno.

    - USB COM port as Serial port Hi All, Here is my problem. I have a USB modem which is exposing COM port with help of usbser.sys. Everything works fine with microsoft Dial up connectoid. When I am trying to use the USB COM port as normal serial port interface through serial IOCTLs it fails. I am accessing the port from my WDM driver. I am able to get the device object pointer of the port and able to dereference the same, but I am failing in configuring the port like set baudrate. Can I use this USB com port exposed in modem as normal serial port interface. Waiting for expert's comments. All your comments are welcome.

    - rundll32 printui.dll,PrintUIEntry Question I did a setup program in VB to install a printer driver using rundll32 printui.dll,PrintUIEntry for a silent installation. When trying it on a PC with Windows 2000 Professional just installed, it seems to have a problem installing. We installed a previous version of our driver and it created the folder C:\WINDOWS\system32\spool\drivers\W32X86\3 and then the setup program worked with the new driver. It seems to be unable to create the "\3" folder. It only works when that folder exist. I would like to know what is the "\3" folder and what creates it in a printer installation. -- Mario Tag: AVStream driver performs differently under WinXP and Win2K. Tag: 63782

Hi all,

I have developed a USB camera driver based on AVStream. So far, the driver
works fine under WinXP platform. The problem occurs when testing the driver
under Win2K (installed with DirectX 9.0c).

I have tested with 2 cameras, one of them managed to stream video, but at a
much lower frame rate (i.e. 1 fps, as compare to 15-30 fps under WinXP);
whereas the other one failed to stream at all, and found that it failed when
trying to retrieve the USB descriptor.

May I know what could be the reasons for the above observations?

Please advise.

Thanks and regards,
yinmun
