    - can display driver access registry? What function can a display driver call to get registry settings. Videoport driver can simply call VideoPortGetRegistryParameters but i wasnt able to find any similar function for display drivers. I really hope there is, but if not how should I store setting information? Tag: is wmi supported by display drivers? Tag: 29576

    - Booting over USB 2.0 (with XP), some success... Hi all, I am attempting to make XP boot over USB (1.1 or 2.0). I know that this type of booting is "unsupported" by Microsoft. In fact, you cant even install XP on a USB drive. However, if the bios supports it, it is possible to boot from USB form a pre-installed version of XP. First, I really think that there is no need for any driver developpement since XP has every driver needed to boot over USB. My first attempt at a boot from USB resulted in a reboot after MUP.sys. Now it crossed my mind that maybe USB was not enabled at boot time so I created a new Group called USB miniport and USB storage and placed usbehci.sys, usbohci, usbhub and usbstor right after SCSI miniport in load order. I also changed the types so that USB is loaded at kernel time. I boot in /sos and see the USB drivers load right after the SCSI miniport. Unfortunetly, no luck I still have a reboot after MUP.sys. I then installed DriverStudio to see if I could write a simple USB mass storage driver to make things work. But after installing DriverStudio I tried again to boot over usb to see what happens with SoftIce and behold: the thing boots! It works even when you skip the boot message stating if you would like to skip the debugging. The only wierd part is that to log in to XP I now need to press cntl-alt-del when it says "loading personnal setings..." when you click on your username because it freezes. I investigated and found that SoftIce creates a group called NTIce that loads 4 drivers: nwfilter, sigvid, sigsym and ntice. Now something in these drivers is causing the USB boot to work. I just have no idea what that is. My idea is that sigsiv is printing a message on the screen saying "Do you want to load .... (press ESC to skip)" and waits a couple of seconds. Is it possible that this give the USB drivers enough time to enumerate the storage disk and boot or are these 4 drivers doing some obscure thing that would suddenly make the USB boot work? I know that sigsiv does more than just print a message to the screen. It must capture mouse events and connect to the VGA adapter to print the message. Maybe this is what is causing the boot to work for some unknown reason... Without this knowledge what approach could I use to boot over USB? Would it be a good approach to write an upper layer driver that would make the glue between USBSTOR and the primary boot disk drivers? Should I write my own USB storage driver which I could then use in the installation of XP using F6 in the textual part? What options do you think would work?

    - AV/C driver help! Hi, I'm trying to make a driver for a AV/C Tuner device, but I have major problems. The driver is there and I can communicate with avc.sys and avcstrm.sys, but I cannot open a stream. I found out that the problem is the hPlugLocal value which make the function fail. I'm not sure where i can get that handle from. Using the result from 61883's CreatePlug didn't gave me any success. I would like to know which function I have to use to establish the connection to the tuner to receive the data stream from the isochronous channel. Is there an example source how to use avcstrm.sys?

    - Which video card registers a driver is setting? I am trying to reverse engineer the Windows 98 driver for a video card in order to find out what hardware registers on the card the driver is setting. To do this under DOS, all I have to do is get the PCI offset in memory of the video card, and then instruct my debugger to break when the memory address corresponding to the register I am interested in is written to. I have absolutely no idea where to begin to do this under Windows, or if it is even possible. Can anybody point me in the right direction on how to accomplish this? Cody.

    - WMI .Put() works on XP, but fails on Windows 2000 I've added some custom OIDs to an NDIS driver we are developing. I also wrote a user app in C# that correctly querys and sets these ULONG values as long as it is run on Windows XP. When running on Windows 2000 I can query at will, but all attempts to set a value fail with a result of WBEM_E_INVALID_PARAMETER. I have a breakpoint set at the beginning of my driver's xxxSetInformation function that never gets hit. I get the same result, (query OK, set object fails, breakpoint never hit), when I access the OID via <windows>\system32\wbem\wbemtest.exe, so the problem isn't in my user level code. I'm running as an administrator in both cases so I don't think there are any security releated issues. Q1) Do I need to configure Windows 2000 in some way to allow write access to custom OIDs? Q2) Does my NDIS miniport driver need to do anything special for Windows 2000 to allow write access? Tag: is wmi supported by display drivers? Tag: 29539

    - Printing from remote machine returns incorrect page numbers Hello! I hope this is the correct newsgroup for this question. I wrote a program using API to monitor a printer queue on a Windows 2000 Server. It monitors all printjobs that are being printed and stores important information like the number of pages printed,... in a database. Monitoring printjobs that are being printed locally is no problem - all the fields are filled with the correct information. If a user prints a document from a Windows 2000 client machine using Word2000 or Notepad I also get all information (but there is a problem in one specific case). Windows 2000 Server local printjob (OK) Word document has 1 page - I print 100 copies Result is: Pages Printed: 1 - Total pages: 1 - Copies: 100 (In this case I can at least calculate the number of pages printed) Windows 2000 Client using shared printer from Windows 2000 Server (PROBLEM!!!) Word document has 1 page - I print 100 copies Result is: Pages Printed: 1 - Total pages: 1 - Copies 1 (????) and even more confusing Windows 2000 Client using shared printer from Windows 2000 Server (OK) Word document has 2 pages (more than 1 is enough) - I print 100 copies Result is: Pages Printed: 200 - Total pages: 1 - Copies 1 (This is also OK for me since I just want to know the number of pages printed) Both server and client are running Windows 2000 SP4 Office verison is 2000 with all SPs but this shouldn't matter since it also happens using notepad,... Also when watching the printer queue in Windows you can see the same information that I explained above. Why does Windows tell that there is just one page printed even if I print 100 copies from a client machine using the shared printer? Is this a bug - and is there a hotfix or some sort of workaround for this? Thank you for your help! Thomas Tag: is wmi supported by display drivers? Tag: 29534

Modifying registry does not help... How these things are getting managed on windows.. We need to this in application or driver?? ipconfig and all utilities does not show changes done in registry till reboot(which is not possible in our case) how dhcp address assignment works dynamically..(without reboot..like winipcfg)??

    - PASSTHRU bugs? Hi, all! I've looked through PASSTHRU (nice pun =) ) recently and found out, that it conflicts with PnP section of IM drivers. 1.DDK states: "No Receives nor Status should be indicated while virtual miniport of NDIS intermediate driver is sleeping" PASSTHRU checks for MPDeviceState at the ProtocolStatus and not retranslates it up when virtual miniport is sleeping, but does not do this for its ProtocolReceive. Is it a bug? 2. DDK states: "No sends nor queries (requests) should be send to lower driver while protocol part of NDIS intermediate driver is sleeping" Again, PASSTHRU checks for PTDeviceState in MiniportSetInformation/MiniportQueryInformation, but does not check it in the MiniportSend nor MiniportSendPackets. Is it a bug? Thank you in advance. Tag: is wmi supported by display drivers? Tag: 29504

    - CYPRESS USB DRIVER Hi all, Let me go right to the point. 1) Is there any substitution for ezusb driver such that allows asynchronous bulk transfers? 2) When the request (for bulk transfer) stalls what is the best way to cancel the request? 3) Suppose I need to arm the driver (issue bulk request for reading to the host) and after that issue interrupt request to the periph to start writing the data. So far with blocked transfer mode, my second request is not sent because host is stalled on the first request. The first request could not be satisfied because only after the second request is sent the data will start coming. If I would have driver with asyncronous capabilities could the second request be processed ealier? (are all requests passed through the same driver's queue in first-in first-out fashion?). I guess if I will send the second request from the other thread it will go to the different driver's queue and can be processed ealier but I don't want to do it becasue of the possible race conditions. Thank You, Dmitri. Tag: is wmi supported by display drivers? Tag: 29500

    - Using IPrintOemUni::ImageProcessing and soft fonts I am trying to use IPrintOemUni::ImageProcessing combined with soft fonts to use unidrv to drive a printer which requires custom compression of low resolution (images, lineart) data as well as custom compression of high resolution (ie font) data. I was hoping to compress the low-res data in ImageProcessing() and then use the TTDOWNLOAD_TTOUTLINE option of TTDownloadMethod() to get the font data separately through calls to OutputCharStr(). However when I try this I find that OutputCharStr() is never called and the text is always rendered at the low resolution. Is what I want to do possible? I have tried all the options to TTDownloadMethod(), and none of them seem to make a difference. Regards, Hank Jones Tag: is wmi supported by display drivers? Tag: 29495

    - Watchdog in WinXP Hi, I want to know if there are any ways to tweak the Windows Watchdog registers/values. One of our Driver functions takes up more than 15seconds (WAtchdog timer value), to complete its operation. And hence the Watchdog fires and the system bugchecks with THREAD_STRUCK_IN_DEVICE_DRIVER. As I cannot reduce the execution time in my driver, I want to know, if there are any interfaces to tweak watchdog registers or parameters if watchdog is emulated in software. Regards, ashok.

    - Where to start learning to program drivers I'm an applications developer and have been for 15 or so years. I'm finding it necessary in my job to work on drivers, including writing a brand new one from scratch. The only experience I have writing drivers is for the old MacOS where I could do whatever I wanted with no real kernel to speak of. With Windows it seems to be a very different story. Where should I begin when learning how to develop drivers for Windows. 9x and 2k/XP? ( I really don't care about NT 3/4 right now ). Are there any books that start from the basics and go from there? I don't need a "for dummies" book but I do need something that starts from the beginning and ends with most of what I need to know to write a fully functional driver.

    - INF XP and 2000 1) How to have XP and 2000 use same INF file. I know we can use OS decorators in sections to keep one INF for both OS. But decorators like .NT, .x86 cannot separate XP from 2000. Is it .xp for XP sections and .NT for NT and 2000? I dont worry about 98 and ME. 2) Can we have different version sections for different OS in same INF. I want to use different class GUIDs for different OS. 3) What should be the classname for 1394 device driver (NOT Host controller driver).

    - PageSize units inconsistancy? UniDrv and .NET We are developing an application that automatically prints pages based on data retrieved from a database. The data includes the printer name and the desired page size. Our printer doesn't support any standard page sizes. We've created our own printer driver based on UniDriver. The printing application can successfully select the desired printer. However, selecting the desired page size doesn't work. We're trying to select the page size using the PaperSize.PaperName property. Here's the C# code: // m_PrinterName is the name recognized by Windows // pageSizeName is the name of the page size matching that in the GPD file. // debug only - look at current default paper size. PaperSize psDefault = pd.DefaultPageSettings.PaperSize; // Create a PrintDocument PrintDocument pd = new PrintDocument(); // Use a standard print controller - to avoid the status/cancel dialog pd.PrintController = new StandardPrintController(); // Set the printer name (from the printer device object) // This name must match the installed Windows printer. pd.PrinterSettings.PrinterName = m_PrinterName; if( !pd.PrinterSettings.IsValid ) { // Log the error and then quit } foreach( PaperSize psize in pd.PrinterSettings.PaperSizes ) { if( psize.PaperName == pageSizeName ) { pd.DefaultPageSettings.PaperSize = ps; // select this one break; } } The interesting thing here is that the units for the sizes (width and height) are not consistant. For the particular test that I'm running I know that the paper size desired is the same as the default size for the printer. But when I look at the properties of the default paper size (psDefault above) and the selected size in the list (when psize.PaperName == pageSizeName ) they don't match: default selected kind: 0x103 0x94 width: 0xde4 = 3556 0x578 = 1400 height: 0x10de = 4318 0x6a4 = 1700 name: "custom" "14INX17IN" The size units for the default appear to be hundredths of centimeters, while the size units for the selected paper size are hundredths of inches. But using the selected paper size doesn't work (the page is too small). The driver seems to want the metric size. The documentation indicates that sizes should be hundredths of inches and that's the unit used in the rendering code. Any idea what's happening here?

    - Differences between inf installation in w98/ME and 2000/XP Hi, Thanks everyone who helped me with some problems some time ago. I built a wizard for installing modem - based on inf files included by manufacturer. It runs properly on 2000/XP, but fails on w98/me. The basic schema is like this: - InstallHInfSection (copies files) - optionally remove "unknown devices" - i.e. modems not properly installed (SetupDiGetClassDevsEx, CM_Get_DevNode_Status_Ex, SetupDiCallClassInstaller - with remove flag) - reenumerate dev node - for root - scans system for new devices This schema installs modem properly on 2000/XP, but fails on W98/ME Last step sometimes runs scanning, sometimes not, and even if it starts the scan, the new hardware wizard shows up and asks for the path to inf file. Could you please help with that? -- K. Support bacteria -- it's the only culture some people have! Tag: is wmi supported by display drivers? Tag: 29415

The device I'm developing for only supports a few page sizes and if I return "not supported" for the other available page sizes, the current application usually gives some kind of scan failed message. I had a similar problem with Resolutions, but I discovered that a registry key could be created in the DeviceData section of the driver that would restrict the available Resolutions.

    - How to set the parallel port into ECP mode? We have found that the parallel port seems to work exclusively in compatible mode even so the pinter is capable of ECP mode. It seems that every time the PC is initiating the parallel port it has to agree on a mode to be in with but it is not making any efforts to change into ECP mode. Can anyone tell me how to convince the PC (driver) to switch the PC parallel chip into ECP mode. Just setting the BIOS into ECP is not good enough. Do we have to write our own LPT low level driver? Can Microsoft help us to do this? Is there a hidden setting in the Registry to enforce ECP mode vs. compatible mode? All help and ideas are very much appreciated in this regard.

    - HCT question Hi. I'm trying to test my HID serial port tablet driver. I'm using HCT 11.2 When running the ACPI S1/S3 test - it can't access COM1 port. The reason is the tablet device is connected to that port and the installed driver captured COM1 port. How can I pass these tests? Thanks. Haim. Tag: is wmi supported by display drivers? Tag: 29356

Since display drivers are not "normal" wdm drivers, I
would like to know if they support windows management
instrumentation (WMI)?

Also, is wmi bidirectionnal? As I understand, wmi is used
to send driver information to user mode application, but
can the opposite by done? That is user mode application
sending information to driver?

Thanks in advance.

Surely! Only WMI events are for driver->app flow, the rest of WMI is for
app->driver flow.
