    - How can I determine the size of one cluster? Hi, all How can I determine the size of one cluster in specified file system, such as FAT32 or NTFS? It is known that: the Default Cluster Sizes can be decided by volume size. for example(For NTFS): Volume Cluster 0 to 512 MB ----- 512 bytes 513 MB to 1 GB ----- 1 KB 1025 MB to 2 GB ----- 2 KB 2 GB and greater ----- 4 KB But how can I get this exact information from system (or some place on disk)? Thanks a lot! Tag: WZC reverting the ssid Tag: 76922

    - Returning order of CompletionRoutines() and IoCallDriver() Hi Let's say I'm a high level driver and i call IoCallDriver to pass an IRP down the stack, and the whole operation is synchronous. There are several devices in the stack (let's say A,B,C,D), each one of them has a completion routine (except D). After device D completes the irp, all completion routines for all the devices are being called, and only afterwards all the IoCallDriver() routines of all the devices return? (or if I'm wrong, what is the right order?) Thanks Tag: WZC reverting the ssid Tag: 76916

    - kernel vs user file name I need to read a file in a kernel mode driver. The file name is passed from a user mode application in the form of "C:\file" or \\Computer\Share\File. Is there a standard kernel or user mode API, or some document describing the proper algorithm to convert "C:\file" to "\??\C:\file" (or "\Device\...."), and "\\Computer\Share\File" to "\Device\Lanman..." (or whatever), in order to make a user mode file name usable in kernel mode? Thank you. Tag: WZC reverting the ssid Tag: 76914

    - IoCompleteRequest() from WorkItem Hi Lets say I'm in PASSIVE IRQL in a dispatch function. I mark my irp as pending. Later, I create a workitem that receives the irp as a context and do some work in it. In the end of the workitem's function, I complete the IRP. Back to the dispatch routine - after allocating and queuing the workitem, I return STATUS_PENDING. Now, because I'm in PASSIVE level, there can be a context switch from my dispatch routine to my workitem's function, so it will run and complete the irp, before I return STATUS_PENDING from the dispatch routine. (it means that when I return STATUS_PENDING, the irp is already completed!) Is there a problem with the above scenario? And if so, how should I handle it? Tag: WZC reverting the ssid Tag: 76904

    - UDF Filter Driver I have written a filter driver that sits inbetween the UDF and various dvd playback applications. In my filter I need to fail a read and get the application to stop playback. I am doing this by setting Data->IoStatus.Status = STATUS_DEVICE_IO_ERROR; Data->IoStatus.Information = 0; WinDvd interprets it correctly and cleanly stops playback. MediaPlayer (and some other players) start playing ugly static out of the speakers and the time counter keeps climbing eventhough it is no longer playing video. I have tried various other status codes but it doesn't seem to matter. It seems like they are not checking the return status... Any thoughts? -- Still trying to build a perpetual motion machine Tag: WZC reverting the ssid Tag: 76887

    - PICs for driver signing in x64 unavailable? I was just forwarded an email response we received from WinQual when we inquired about getting a PIC for signing our drivers for the new x64 signing policy. I'm hoping I'm just over reacting, but... I was disturbed to hear that they are not available at this time. In fact, there was a strong implication in this email that PICs would not be available until the last release candidate for Vista. Here is the relevant portion of this email: "This is not available yet, but should be in time for Vista launch. The PIC is a new signing program for files we couldn?t sign before. We?ll be making more announcements regarding the availability of PIC to sign drivers as we get closer to the Vista logo program launch, which will be at the last Release Candidate." Microsoft has done this in the past (i.e. not releasing full WHQL tests, signing tools, etc. until just before RTM), and it always has caused problems. So I'm trying to head this off at the pass this time. I don't know about the rest of you, but we need time to get a PIC, integrate signing with it into our build process, build a driver, test it internally, fix any problems that signing caused (and rebuild and retest) and deliver a candidate driver to the OEMs early enough that they have time to test it themselves (and get any needed bug fixes) before their deadline for burning a golden master for manufacturing of their first x64 machines. And that's assuming that the Vista Beta community doesn't find any bugs in the kernel embedded signing code in Windows... I'm crossposting this to m.p.d.d.d because I think this issue is of wider interest than just the winlogo newsgroup. And yes, I've already sent an email to WinQual about this. -- Ray Tag: WZC reverting the ssid Tag: 76867

    - Bug in CDROM.SYS In DDK2000...WDK 5112, CDROM.SYS!CdRomInterpretReadCapacity contains the following code: ---------------------------- // // Calculate media capacity in bytes. // commonExtension->PartitionLength.QuadPart = (LONGLONG)(lastSector + 1); // // we've defaulted to 32/64 forever. don't want to change this now... // fdoExtension->DiskGeometry.TracksPerCylinder = 0x40; fdoExtension->DiskGeometry.SectorsPerTrack = 0x20; // // Calculate number of cylinders. // fdoExtension->DiskGeometry.Cylinders.QuadPart = (LONGLONG)((lastSector + 1) / (32 * 64)); commonExtension->PartitionLength.QuadPart = (commonExtension->PartitionLength.QuadPart << fdoExtension->SectorShift); ---------------------- The code rounds the number of cylinders to (32*64) for DISK_GEOMETRY, which results in a wrong value returned to the caller. The number of sectors becomes wrong, too (TracksPerCylinder * SectorsPerTrack * Cylinders). IOCTL_DISK_GET_DRIVE_LAYOUT and IOCTL_DISK_GET_PARTITION_INFO return the correct media capacity in PARTITION_INFORMATION.PartitionLength. The difference between PARTITION_INFORMATION and DISK_GEOMETRY prevents certain filesystems, including NTFS, from being mounted from CD/DVD/BD/HDDVD/... >> // we've defaulted to 32/64 forever. don't want to change this now...

    - unidrv plugins and dialog boxes I have been having difficulty trying to determine where it is possible to display a dialog box from a unidrv plug-in. From what I read in the documentation it appears as though both UI and rendering plugins run in the application's context, before anything is sent to the spooler. If this is indeed the case I would assume that it would be possible to display a dialog box to capture document specific properties during EnablePDEV processing in a rendering plug-in. This would allow me to capture things like fax #s for each document by displaying a dialog to the user who started the job. I further assume that the dialog box would appear in a particular user's termnal services window. Are my assumptions correct or am I completely out to lunch? If I am out to lunch what would be the easiest way to capture fax #s for each individual document in a terminal services environment? Tag: WZC reverting the ssid Tag: 76853

    - Causes of USBD_STATUS_ISO_NOT_ACCESSED_BY_HW Greetings, I realize in my previous post "NEC B1 HC chokes with full BW USB2 ISO IN stream" my primary question was hidden in a flurry of details. Can I be doing something in my USB camera driver to cause the USBD_STATUS_ISO_NOT_ACCESSED_BY_HW error I am seeing with the NEC host controller? The only thing I have heard of that causes this error is URB starvation. That is clearly not the trouble. I am queuing 10 URBs of 32 packets each. Also, the driver works perfeftly under the VIA controller. Is there some subtle error I might be causing that effects the NEC controller but not the VIA one, or is there simply a bug in the NEC controller?

    - NEC B1 HC chokes with full BW USB2 ISO IN stream Greetings, I have tracked down a bug that looks for all the world like it is caused by the NEC B1 HC on the Adaptec USB2 PCI interface card I have. The host is a MP Athlon system running XP SP1 with the Adaptec card using the NEC B1 EHCI controller and a separate VIA EHCI controller on the mobo. Both controllers are using the Microsoft usbehci.sys driver version 5.1.2600.1243. When running a full bandwidth ISO stream from a USB camera (3072 bytes/microframe), the NEC controller chokes with USBD_STATUS_ISO_NOT_ACCESSED_BY_HW (c0020000). It does it horribly when running on a MP boot. If I run on a UP boot of the same machine (same HC driver), it is still there but not as bad. Now if I switch the camera over to the VIA controller, everything else I think exactly the same, the error goes away entirely. It is gone on both the MP and UP boots. Before I checked the VIA HC, I thought it was the camera being too slow and not responding to the IN token in enough time. But after seeing the difference with the VIA HC, I looked a little more carefully and saw on my bus analyzer that indeed the IN token is never sent. So it is clearly on the host end. It is always the third transaction in the microframe that fails; after two successful transactions. I was really surprised that a HC would fail like that. I looked online to see if there were any known troubles with that particular HC, but I did not see anything. Anyone have any ideas?? Best regards, Tom Udale Tag: WZC reverting the ssid Tag: 76819

    - IRQL in TDI filter dispatch functions Hi I'm developing a TDI filter driver. a. According to the MSDN, IoCallDriver() can be called at IRQL <= DISPATCH_LEVEL. Therefore, should I assume that it is possible for all dispatch routines in my TDI filter to run at IRQL = DISPATCH_LEVEL? (According to MSDN this rule is right for all kinds of filter drivers?) b. My completion routines are being invoked in an arbitrary thread context and probably at high IRQ. Is this also right for a TDI filter? c. When code can run at IRQL => DISPATCH_LEVEL, all the allocations on the STACK also need to be none paged? (Do I need to use paged_code macro or something like that?) Thanks.

    - How to get started with creating a virtual filesystem?

What kind of component do I actually need to write, at a minimum? If I understand well, I would need to somehow create a fake volume and tell Windows (I/O manager?) about it, register my own filesystem and make Windows forward all requests to this fake volume to my filesystem instance, with which I would interact via ioctl.

If it's a ControlDeviceObject it's going to look if something is send from the user application. In this check im looking if my own made IOCTL is send or not, if so i want to add an mousepackage. The problem is i need to main device to send the package to but at this moment i get the ControlDeviceObject all the time. I also tryed to save the address of the Main DeviceObject and use it when i needed to enter the package, but i think that isn;t even possible since maybe it has something to do with the Passing through of the IRP and the completion of it(what maybe would explain the error)?

    - drivers for embedded graphics Hello. Anyone know anything about embedded VIA UniChrome chips? I want to run NT4 server on a CLE266 board with embedded UniChrome 3D. I don't care about 3D or video accelleration, but I do want something more than 640x480x4 resolution. VIA doesn't have an NT driver for the CLE266 board, but I did find an NT driver for an M400 board with embedded UniChrome Pro. Could that driver be used to set display resolution? (A VIA tech suspected 'no' but was not certain.) Barring that, how difficult would it be to develop an NT driver that provided no chip-specific functionality besides mode change? thanks, nf Tag: WZC reverting the ssid Tag: 76766

    - Max contiguous memory buffer size Hi! I have a Windows 2003 Server x86 64bit running on system with 16Gb memory. How much contiguous memory can I allocate for device DMA buffer? Device is the PCI-x adapter with 64bit address bus. I want to get 4Gb DMA buffer. Are there any reccomendations to tune operationg system for getting maximum size DMA buffer? Thanks!

    - EngMapFile I have a mirror display driver that uses a memory-mapped file to push screen updates to an application that reads the updates from the file and sends them to a server for distribution. The user-level application creates the file and passes the name to the driver. The Driver uses EngMapFile to open it. Sometimes it fails and the application retries using a smaller size until it succeeds or reaches a minimum size and fails. I am guessing that EngMapFile fails because it uses non-paged system memory to back the memory-mapped file and since this is a limited resource there may not always be enough available for the full size of the file. Can someone verify this for me? The documentation for EngMapFile is very minimal. Thanks, Bill Wyatt, Sonexis, Inc. Tewksbury, Massachusetts. Tag: WZC reverting the ssid Tag: 76751

    - WPP tracing produces empty .etl file <apology> First, let me apologise if you are reading this twice. I posted this originally to the win32.programmer.kernel newsgroup before I spotted this one ! I thought this one might be more relevant. </apology> I'm attempting to use WPP tracing in my XP kernel driver. I've followed all the instructions at osronline and in MSDN, but I'm always getting an empty .etl file. I've added the WPP_DEBUG macros and I can see the messages being dumped to DebugView. Does anyone have any idea what I might be doing wrong ? Here is my tracelog -start call tracelog -start wavedrvlog -guid wave_wpp.ctl -flags 0x1 -f wavedrv.etl wave_cpp.ctl contains : d8580821-5d64-541f-aac8-c8dbaf80ea62 wavedrv And, finally, my WPP_DEFINE_CONTROL_GUID WPP_DEFINE_CONTROL_GUID(wavedrv,(E2E85950,7BFF,4ab7,8A0C,A1AD7AC8C1D5), \ WPP_DEFINE_BIT(WAVEDRV_DBG_ALL) ) I am concerned that tracepdb produces 2 .tmf files that do not match my GUID. Is this normal ? I do get a .tmc file which has the correct GUID. When I run tracefmt, it says it is using default.tmf and finished with Exit Status 38. I can't find any information regarding this exit status ! What does it mean ? Why is it using the default.tmf instead of my tracepdb versions ? For completeness, here is my tracefmt call tracefmt -o wavedrv.txt -f wavedrv.etl -p c:\tmf ("c:\tmf" does contain my .tmf files) After sorting my build problems out the other day, this has started to frustrate me even more. Am I missing something obvious ?? - WinDDK 3790 - W2k3 Checked Build Environment Thanks for ANY help/advice you can offer Cheers Ged Tag: WZC reverting the ssid Tag: 76750

    - Direct I/O Hello ! I've an old software (for win95 & 98) who accessing the serial port com for communicate with automatism... But this software is accessing directly to the port com (with IN & OUT C) . With win95 & 98 it's ok, but with nt2000 and xp not. How can i write a driver for intercept I/O from my application and write to serial port com ? Thank you Tag: WZC reverting the ssid Tag: 76747

I am working on setting SSID on my wireless network card uisng winddk using
ioctl commands.

For setting ssid, the steps i am using

1. For open network

Stop WZC
Set InfrastructureMode
Set Ndis802_11WEPDisabled
Set SSID
strat WZC

its working fine

1. For secured network

Stop WZC
set Ndis802_11AuthModeOpen
Set InfrastructureMode
Set SSID
Set Ndis802_11WEPEnabled
Set ADD_WEP_KEY

till here its fine it get connected
starat WZC ---> WZC reverts back to other SSID. So starting WZC causing
the issue.What can I do to avoid it.

Avnish.

its working fine

When you restart WZC it will go off and do its own thing because it does NOT
know anything about your software. All it knows is that it has been stopped
for a while.

1.) You can leave WZC truned off. The management of the 802.11 connection is
solely under your control.

2.) Or you can turn WZC on and the management of the 802.11 connection is
solely under the control of WZC.

You must understand that one 802.11 adapter cannot obey two masters. Only
WZC _OR_ your software.

On XP SP2 and WS2003 the Wireless Provisioning Service may be useful to you.

Good luck,

Hey, if you do not want WZC to touch your device - just make it invisible to
WZC.
Return OID_GEN_PHYSICAL_MEDIUM = NdisPhysicalMediumUnspecified.
Enjoy.
