    - msvcr80.dll and msvcp80.dll used in in print driver I am developing a print driver which contains a dll which depends on msvcp80.dll and msvcr80.dll. How do I add these dependents to my INF such that they are managed properly? Do I need to include the manifest file somehow? For the heck of it, I tried treating them like any other file in my INF and was able to install the driver, but the printer failed to install, and I received a "Resolve Partial Assembly failed for Microsoft.VC80.CRT. Reference error message: The referenced assembly is not installed on your system." in the event viewer. The dependency walker looks fine when examining files in the destination user mode directory. I've had no luck finding an answer in the MSDN or WDK docs. Tag: video child device in Windows Vista Tag: 101107

    - slow boot windows xp Hello, For a couple of mounts, I'v a slow boot of windows xp on my acer laptop 9412. First, I thought a virus or rootkit but the tools I tried don't find anything of important (S&D, AVG, Bitdefender, SDoctor). Starting in save mode works better but also slow. Bootvis isn't helping me very well. It only shows often 100% disk use during boot which I knew already by the HD led. Watching processes with process explorer from sysinternals, I see a lot of interrupts during boot; around 45% CPU use during boot. Using process monitor, I see a long file time in the file summary for c:\$ConvertToNonresident (around 45% of total file time). I suppose there is an NTFS problem but defragmentation doesn't help. I hope this newsgroup has the knowledge what is the problem or what causes it. What is happening ? How do I solve this slow boot problem ? In the stack summary, I see some <unknown>. I suppose that's normal ? Tag: video child device in Windows Vista Tag: 101102

    - NtShutdownSystem Vista compatibility Hello everyone, I am using NtShutdowSystem in my native application which is working great with Windows Xp and in case of Vista, it restarts system properly but afterwards gives a "Windows Recovery Screen" (hope this is familiar) of which if we choose "Start Windows Normally", everything works fine. The problem is why I am getting such a screen in Vista and not in Xp? How can this be fixed? Adding to above, autochk.exe in Vista does a restart without any problem at all, so there must be some way for sure. Thanks in advance. Tag: video child device in Windows Vista Tag: 101100

    - CreateFile fail to open device I am working on a mouse filter driver which has two device objects. One is the conventional device object shown in DDK, the other one is a named device object transfering some data out. The question is I can find two objects in namespace viewer but createfile() can not open the secound named object. Code in driver .h #define NT_DEVICE_NAME_STRING L"\\Device\\MIOCTL" #define DOS_DEVICE_NAME_STRING L"\\DosDevices\\MTest" // ==Symbolic_name_string .c RtlInitUnicodeString(&ntDeviceName, NT_DEVICE_NAME_STRING); RtlInitUnicodeString(&symbolicLinkName, DOS_DEVICE_NAME_STRING); status = IoCreateDevice(DeviceObject->DriverObject, sizeof(CONTROL_DEVICE_EXTENSION), &ntDeviceName, FILE_DEVICE_UNKNOWN, FILE_DEVICE_SECURE_OPEN, FALSE, &ControlDeviceObject); status = IoCreateSymbolicLink( &symbolicLinkName, &ntDeviceName ); Code in app (hDevice = CreateFile( "\\\\.\\MTest", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL) The test application returns system error code #2 "can not find file" . Who can tell me how to open this device in filter driver? Is there some utilities I can view the dos devices? Thanks in advance, Tag: video child device in Windows Vista Tag: 101097

    - Driver Problem with Canon LBP2900 Printer Hi Folks, Unfortunately, I encounter a problem with my brand new laser printer Canon LBP2900. It is connected to my computer (Windows Vista) via an USB cable and works properly as long as I am offline. But once I go online, data transfer from the computer to the printer will take several minutes. This phenomenon seems not to depend on the size of the file to be printed. Pages are not printed stepwise (with time interruptions between different pages) but in one single go once printing is initiated. I suspected the firewall (Norton) to be responsible for this delay. But even if I turned it off, delayed printing did persist. I have already uninstalled the printer driver and reinstalled when I was online with no effect on the slowed data transfer to the printer. During data transfer, the program I want to print from (Word, Adobe Acrobat etc.) seems to be pretty busy (task manager will temporarily show 'Not Responding'). When I want to print a PDF, the green status bar will rest at zero percent for ages. Then (after several minutes) it will abruptly turn to 100%. I would be very pleased if somebody could give me some advice here. Thank you so much. Regards Ulf Tag: video child device in Windows Vista Tag: 101094

    - SpinLock in DPC and IOCTL Hi, I use a spin lock to synch my IOCTLs (which can be called from several user mode clients), and my DPC. How will the system behave in the next scenario: IOCTL xxx has been called, and starts to run in PASSIVE_LEVEL and aquires spin lock MyLock. During its excecution, an interrupt has been triggered by the hardware, and a DPC starts to run in DISPATCH_LEVEL, aquiring MyLock. Will it waits to MyLock to be released (which means that DPC waits for IOCTL to be completed) or will it run ignoring the lock (because its in higher IRQL)? Thanks, Avi.

    - how can I kernel debug NDIS IM driver "passthru" example in VMWare?! After I install the "passthru" in vmware succesfully, then connect to vmware using windbg, and set some breakpoint on "PtReceivePacket" or MP* functions, it simply doesn't stop there. I use bridged mode in vmware for the NIC. I can surf the internet in the vmware machine, does this mean that the packet doesn't go through "passthru"?? Thanks for any reply.

    - Running DTM in VMWare I tried to run the NDISTest for my CoNDIS WAN virtual virtual adapter. Since the current NDISTest is boundaled with DTM, I need to install the DTM controller and studio in a server in oder to run the NDISTest. What I did is as follows. 1. Install DTM controller and studio in a server runnning a VM. 2. Install my CoNDIS Virtul WAN and DTM client in Windows XP running in a another VM. In the above configuration, I can create the machine pool to monitor the job without any problem. But when I tried to create a submission, it always fail in a few steps after running the Wizzard. Does anybody have any experiece to run the DTM on a Vmware? If I cannot run the DTM in the VMware, can I just run the NDISTest in the VMWare? then how?

    - Writing a USB device driver for a trackball I have a mouse and a trackball on my pc. I would like the mouse to act as normal mouse that controls the cursor. I would like the trackball to act as a separate device which does not act like a mouse. Right now, when I plug both in, I get two mice. The trackball uses HID-compliant mouse driver in the device manager. I was hoping to write a new driver and install it instead of the HID- compliant driver. I could then use the new driver in my application to simply read delta x and y from the trackball. Could anyone give me some ideas on this? Is there any similar source code that I could modify? I open to other methods too. I examined using Raw input but ran into so roadblocks. Tag: video child device in Windows Vista Tag: 101075

    - Printer UI Plugin Hi, after reading a lot of documentation about UI and rendering plug in , I would like to know if I well understand. with rendering plug in, I can intercept the data flow sent to te printer through the print job , for example. and with UI plug in, I can add property page to the print document or print device, and store setting data into the registry. Now, I think that I can only communicate with the printer through the rendering plug in, and so , I wonder how to send data directly to my printer from my UI plug in without to execute a print job. I think I don't understand all the process of the printing. If anyone can help me, I really appreciate. and sorry for my poor english. thank you Tag: video child device in Windows Vista Tag: 101068

    - What does it take to get PCI bus master privileges in Vista? I have a pair of NDIS drivers that sit on top of a bus driver that controls a PCI device. In Vista32 one NDIS driver that sits on top of our bus driver calls NdisMSetMiniportAttributes with the attributes flag set to NDIS_MINIPORT_ATTRIBUTES_BUS_MASTER. I can allocate shared memory. In Vista64, the same driver, the same source code, the same call to NdisMSetMiniportAttributes, with the same attributes flag set to NDIS_MINIPORT_ATTRIBUTES_BUS_MASTER, and I CAN NOT allocate shared memory. What other things does this NDIS driver have to do to join the 64 bit bus master club? Thanks -Ron- Tag: video child device in Windows Vista Tag: 101043

    - Vitsa driver load reload problem I know I've seen commants on this before but Google is just swamped with stuff relating to 'Vista' and 'driver'. I have a little test utility to exercise a driver I'm working on. As a convienence, it contains buttons to spawn devcon commands to install/update/restart my driver. The update button (via the .inf) causes the latest build of my driver to be copied to system32\drivers and then fires up the new code. All this works great on XP. On Vista, either the copy takes place and it gets overwritten by the previous version or the copy never takes place. The automatic driver restore monster seems to be in the game. Is there any magic that can be applied from the command line (i.e. devcon) to make Vista behave? The driver is in a system defined class and is signed using a test certificate (pending receipt of real certificate) Thanks, Mickey. Tag: video child device in Windows Vista Tag: 101028

    - how to use pvOut in DOCUMENTEVENT_CREATEDCPRE Hi, The documentation given in MSDN for pvOut variable for function IPrintOemUI2:DocumentEvent with iEsc DOCUMENTEVENT_CREATEDCPRE is as follows: Pointer to a driver-supplied DEVMODE structure, which GDI uses instead of the one supplied by the CreateDC caller. (If NULL, GDI uses the caller-supplied structure.) I am implementing my own ui plug in. In this plug in i am trying to change the values of some of the public devmode member variables. I tried assigning the new values to members variables of pvOut. Even though the change is reflected in iEsc DOCUMENTEVENT_CREATEDCPOST, the change is not reflected in the print job. ie if I change pvOut- >dmDuplex to DMUP_HORIZONTAL from DMUP_SIMPLEX, the print job is still simplex. The above problem is observed in MSWORD and other office applications. It works fine for notepad, adobe reader etc. Can I any one point out the right way to store the devmode settings?

    - Using Event Object in overlapped I/O operation : GetOverlappedResult is blocked... In 1394api.dll source code (:\WinDDK\6000\src\1394\dll\1394api\isochapi.c) for 1394 WDM driver, there is an overlapped I/O operation for 'Isochronous Attch Buffers'. It creates a manual-reset event object : ------------------------------------------------------------------------ overLapped.hEvent = CreateEvent( NULL, TRUE, FALSE, NULL ); ------------------------------------------------------------------------ with a ResetEvent function : ------------------------------------------------------------------------ ResetEvent(overLapped.hEvent); ------------------------------------------------------------------------ After that, it calls DeviceIoControl function with &overlapped : ------------------------------------------------------------------------ dwRet = DeviceIoControl( hDevice, IOCTL_ISOCH_ATTACH_BUFFERS, pIsochAttachBuffers, ulBufferSize, pIsochAttachBuffers, ulBufferSize, &dwBytesRet, &overLapped); ------------------------------------------------------------------------ It waits for pending operation by calling GetOverlappedResult function with : -------------------------------------------------------------------------------------------------- if (!GetOverlappedResult(hDevice, &overLapped, &dwBytesRet, TRUE)) { //getoverlappedresult failed, lets find out why... dwRet = GetLastError(); TRACE(TL_ERROR, (hWnd, "IsochAttachBuffers: GetOverlappedResult Failed! dwRet = %d\r\n", dwRet)); } --------------------------------------------------------------------------------------------------- Unfortunately the sample application freezes by calling GetOverlappedResult function. As far as I understood, GetOverlappedResult function with 'bWait = TRUE' does not return untill the pending operation has completed. But I can't find the 'SetEvent function' for our manual-reset event object. Shouldn't there a SetEvent function to set the manual-reset event object explicitly to the signaled state? Could these be the cause of application freezing? Or did I miss something? Can somebody explain this? Thanks in advance, min p.s On DebugView, it seems that the pending operation has completed...

    - IFS Filter and File Sizes Dear all, I am writing a small filter driver to hone my skills and I am not sure if something I am trying to do will produce guaranteed results! I would like to be able to always know the size of a file (end of file length) based on filtering Irp and Fast IO writes and set informations. This seemed like a valid approach. However, am I right in thinking that if a file is memory mapped, the size could change without getting an Irp or Fast IO call via the cache manager? In which case there would be times that I would not know the size of a file unless I asked the FS/Cache Manager? Many thanks in advance? Carl Tag: video child device in Windows Vista Tag: 100974

    - Multifunction, WDF and wait/wake issues Hi, This might sound an awkward question, but I'd appreciate if someone from msft/wdf team could point me to the right direction. I have a multifunction PCI device with two functions. Function 0 is handled by a WDF function driver and function 1 is handled by a WDF bus driver, enumerating a number of child devices which will then use a WDM driver. Both of functions are capable of waking the system up from any Sx state. The problem is under XP SP2 as long as the WDF bus driver is loaded (device is in D3), I'm not able to wake the system up by function 0. If I disable function 1, replace the bus driver for function 1 with it's equivalent WDM driver or if I run same tests in Vista, both functions will be able to wake the system from Sx without a problem. What I don't understand is why and how one driver could prevent the other from waking up the system? Are there any reports of difficulties getting WDF bus drivers for PCI enumerated devices working properly? Also what's the best way of attacking this scenario? I've already tried to investigate code paths, KMDF logs and the state of power IRPs (using !poreqlist) but couldn't see any obvious problem. Thanks.

    - Driver installation using "setup & deployment" wizard? Is Driver installation can possible to install using "setup & deployment" wizard? under setup wizard? I have tried to use this, but it is installing in the C:\programfile\setup1(name)\ Is Add Hardware Update wizard is required to run here to show the inf, sys & relavent files? Is "setup & deployment" wizard? uses DIFxApp for installation?, if so, Is DIFxAPP is only for installing the applications?, not for drivers? I would like to use the Microsoft windows installer for instlling my driver & application files, can anyone suggest any easy method for end user, so that, he dont need to worry about these?

    - Can FSCTL_MOVE_FILE move $Mft? Hello Everyone, I am trying to move $Mft using FSCTL_MOVE_FILE on Windows XP. CreateFile opened $Mft with no problem but FSCTL_MOVE_FILE returned error 87 which is INVALID_PARAMETERS. I am not able to understand how parameters are invalid because same call is working fine for all other files. Is it that FSCTL_MOVE_FILE cannot move $Mft? or if it can then how? Thanks a lot.

    - MmGetSystemAddressForMdlSafe Question Hi friend I hava a question about MmGetSystemAddressForMdlSafe function. This Function can translate a virtual address range, which is described by the MDL at Irp->MdlAddress, for a user buffer to a system-space address range. The Question is after I map the user buffer to kernal space by this function, do I need to unmap the buffer and how to do that? On my understand ,Mapping a buffer means allocate system page entries to discribe the relationship of virtual address and phycial address. if we don't need the map ,we must free the system page entries ,unmapping. But after search the DDK, I find the DDK does not metain the unmapping in this case: it said the call sequence is: MmProbeAndLockPages MmGetSystemAddressForMdlSafe MmUnlockPages IoFreeMdl Can somebody explain for me ? thanks very much!! rech Tag: video child device in Windows Vista Tag: 100950

    - NDIS OID Query Hello, I am trying to read the current BSS list from a network driver. This is done using a client application written in C#. C# application shows some junk values as last entry for the BSS List. For the last entry, there is no channel,RSSI values, SSID etc. I am accessing this BSSID List OID using WMI class. I have added error log in OID case statement. Windbg shows information about each network and writing all values like SSID,channel, RSSI etc into log. But C# application shows less number of entries and last entry is junk. I don't know instance of WMI class returns less number of entries and inproper last entry. Is there anything wrong with WMI class? or Query part? How do I resolve this issue? Thanks Tag: video child device in Windows Vista Tag: 100949

    - Difference between "FILE:" port and "Local Port"(save to a HDD file), Hi, I am creating print driver PRN files by using "FILE:" port on Windows2000 pro, but I found I also can create "Local Port" for a print driver to output its PRN files to a disk file. I would like to know if there is any difference for output PRN files by using "FILE:" port and "Local Port"(save to a HDD file), if so, I also would like to ask what is the difference between them.

    - Banks are bad but which one is worse? FirstTech Credit Union of course!! I had a few horror experiences with them. They refused to complete my billpay that I had 25 times available fund to pay for. They yanked my money out as a penalty and provided no beneficial service in return, making excuses saying "wrong suffix for the transaction". When you call in you to ask questions, you got to remember your global password crap, you got to provide your pin to remember # to use your card (I know it's normal for this one, I got to list how many thing you have to remember after million things in your life), if you failed to remember the suffix even when you have your Insufficient Fund Protection, it won't help, they just won't want to move your fund to pay off your bills because they wanted to make ungodly money from you. They already made so much money off your money in their bank, FirstTech is just too greedy, they won't admit it. If I were you, I would move to the safer banks before they yanked all my moneys out.

    - text missing in bitmap When a certain application sends a bitmap to my printer driver via a BitBlt, all of the text is missing. All of the Lines and Fills that were drawn to the bitmap are all okay. It's only the text which is drawn to the bitmap with TextOut that is missing. When I attached WinDbg to the applcation and do a print, I see the BitBlt coming to my driver as a DrvCopyBits(). It's curious that, if we alter the application to render the Text to a path and then use StrokePath to render the text outline to the bitmap, the text will appear. This application works fine with other printer drivers. Any ideas as to what would cause the text (more specifically, pixels representing the text) to be missiing from the bitmap? Don L.

I would like to monitor the memory allocations in some manner from within the driver operation - and not with an external application (as poolmon). also, I want to do it on a constant basis, so kernel debugger is not an option. Is there any way to do this? Tag: video child device in Windows Vista Tag: 100911

Hi !!
I want to create a video child device using video miniport in
Windows vista, so I 'm writting non pnp kernel mode driver which
creates a FDO and attaches the fdo to PDO (e.g \\Device\\Video3)
using IoAttachDeviceToDeviceStack.

Now How can i create child device for this video device ?

Thanks in Advance

1) You need to be a pnp driver
2) you need to install yourself as an upper filter driver for the
particular video card. This way you will not have to bind to a specific
device name, rather it will be given to you
3) use KMDF to write the bus driver, it is not that simple to do (and it
appears that you have not written WDM drivers before as evidenced by trying
to add a non pnp device to a pnp stack)

The XPDM video-stack is not that easy to reconfigure.
If you have a non PnP device, then,
simply call VideoPortInitialize in DriverEntry, and, have videoprt.sys
to create the device for you, either on the spot, or through some
out-of-band simulation of PnP.
