    - Developing a Bitmap Printer Hi all, My aim is to develop a bitmap printer Here are some things that are puzzling me... 1) Can I extract raw image data from the postscript printer and convert it to viewable bitmap image? If yes, then where should I be ideally looking to get the image data...Renderer, spooler or somewhere else? Will the image data be stored in a buffer or in some memroy DC? 2)Should I try extracting data from the universal printer?will it be easier? If yes, then where exactly should I be looking for the image? 3)Can I solve my problem by changing the minidriver?or does it just control the printer features and has nothing to do with file image extraction? 4)Is a plugin required to get this done or will I need to change some existing code? 5)Once I get the 'raw' image, will I need to do some processing on it to convert it to bmp, like adding tags or such? I'm also hoping to develop a pdf printer, so if I go with the postscript printer I may need to just develop one printer in the long run. Any pointers and help in this direction will be much appreciated. -- ***ljose*** Tag: Printer folder Left Bar Tag: 65651

    - problem in installing a driver using DPinst.exe (DIFx V2.0) Hello, I have a legacy driver (not signed) that I like to install using DPInst.exe part of DIFx 2.0. I used the provided toaster sample installation XML as the basis. I add a line to it after <dpInst> as follow to the file so I can install my unsigned driver: <?xml version="1.0"?> <dpInst> <legacyMode/> <language code="0x0409"> and left all other sections of the file the same. It doesn't install the driver and complain that the driver isn't signed. When I run dpInst.exe with /lm switch, it will install the driver successfully. What is the problem with XML file? Am I set the switch correctly in the XML file? Best regards Tag: Printer folder Left Bar Tag: 65647

    - Pending IOCTLs and Slow User Mode Response I've written an NDIS IM driver that forwards notifications to a user-mode app via a pended IOCTL. The app has 32 threads that simply call DeviceIoControl and then queue the notification up for another consumer thread. The problem that I'm seeing is that under heavy stress, where the driver needs to notify the app, I see the number of IOCTLs plumbed by the app stop, with the result that the driver runs out of pending IOCTLS/IRPs. Each thread of the user mode app calls DeviceIoControl() in a non-overlapped manner. Would calling this with an overlapped structure (and opening the file with FILE_FLAG_OVERLAPPED) help?

    - [Audio Driver] - Volume Control Is there any guy who can control the volume in a driver? We have a filter driver which catch a data from the stream and process the data then put it back to original stream. I found some problems in dealing with the audio data so I want to set the volume, especially microphone volume. In case of Master Volume, I can get this information from KSPROPERTY, KSPROPERTY_AUDIO_VOLUMELEVEL, but I can't get any information about microphone volume from this. So question is that How can I get the volume level of Microphone or Line-in? Thank you. SAM Tag: Printer folder Left Bar Tag: 65622

    - Installing Port Monitor INFs Programmatically Is it possible to programmatically install a port monitor without using AddMonitor or the Server Properties UI? I ask becuase I have tried to use InstallHinfSection to install the ddk sample portmonitor and that fails. Also using "install" from the inf context menu fails. Is this unsupported or is there possibly something wrong with the inf file... or the parameters to InstallHinf section?

    - Is this code SMP safe? Hi, I am new at driver programming. I was wondering is the following code is SMP safe or would I need spinlocks around the indicated statements. //My device extension declaration typedef struct _DEVICE_EXTENSION { PIRP pCurrIrp; BOOL start; KEVENT evIoctl; } DEVICE_EXTENSION, *PDEVICE_EXTENSION; //My Dispatch routine (called w/ PASSIVE_IRQL) NTSTATUS MyDispatchRoutine(..., IN IRP pIrp) { ... //myPdx points to my device extension ... switch (controlCode) { case IOCTL_GET: if (!myPdx->start) <====spinlocks around this needed? { //IoCompleteRequest with error and exit } if (myPdx->pCurrIrp) <====spinlocks around this needed? { //IoCompleteRequest with busy error and exit } ........ InterlockedExchangePointer((PVOID*)&myPdx->pCurrIrp, pIrp); //wake worker thread KeSetEvent(&myPdx->evIoctl, IO_NO_INCREMENT, FALSE); ....... break; case IOCTL_START: InterlockedExchange((LONG*)&(myPdx->start), TRUE ); .... ....//IoCompleteRequest with ok break; ..... ..... } } //My executive worker thread which is signalled by the IOCTL above // (called w/ PASSIVE_IRQL) void MyWorkerThread(void) { ...//myPdx points to my device extension PIRP pIrp; ... ...//Acquire mutex (stored in dev. extnsion; not shown) to serialize ...// this thread execution vs. other instances of this thread ... if (myPdx->bCaptureSound) <====spinlocks around this needed? { KeWaitForSingleObject(&myPdx->evIoctl, Executive, KernelMode, FALSE, NULL); KeClearEvent(&myPdx->evIoctl); pIrp = myPdx->pCurrIrp; <====spinlocks around this needed? ........ InterlockedExchangePointer((PVOID *)&myPdx->pCurrIrp, NULL); ........//do other stuff .......//release mutex acquired above for serialization } I have indicated where I am confused about the spinlock thing. For writing to any variables in my device extension I use the InterlockedXXX functions but during reading of those variables, do I need spinlocks or some other protection? My understanding is that any "regular" read statement (such as "pIrp = myPdx->pCurrIrp") comprises of multiple machine instructions (ie. non-atomic) during which the scheduler can swap out the process and another process can modify the data resulting in corruption. Is this reasoning correct?? On a uniprocessor system I have seen that the worker thread execution is interspersed with the dispatch routine. But since in the worker thread I am working with the pointer to myPdx->pCurrIrp called pIrp, the dispatch routine is free to modify myPdx->pCurrIrp. So things work out fine w/ no lost IRPs. I wonder if things would change in an SMP machine. I know I asked a mouthfull (screenfull?) and I appreciate all tips. Thanks & Regards, James Tag: Printer folder Left Bar Tag: 65619

    - SysHook and STATUS_ACCESS_VIOLATION Hi, Recently I've attempt to write a driver in order to hook any registry access using the KeServiceDescriptorTable and then subst the table entry with my function. If I use the this code only for logging (ie. RegMon) it's all ok, but if I try to modify the parameter all the Zwxx function give me a STATUS_ACCESS_VIOLATION: for example: - if the key that the application want to open is \Registry\Machine\Software\Test I create (ExAllocatePool) a new POBJECT_ATTRIBUTES and relative PUNICODE_STRING - then I call the RealZwOpenKey (the real KeServiceDescriptorTable's function) but If I do so the function give me the error. But, If I dehook the ZwOpenKey and the I call ZwOpenKey the Fn is Ok. But dehooking this Fn isn't good (some access could be lost). It seems that the real ZwOpenKey's code can't or don't want access the memory allocated by the driver... thank's Tag: Printer folder Left Bar Tag: 65602

    - Neophyte question on SMP & mutexes Hi, Do mutexes protect against concurrent access from another CPU? I have a worker thread which acquires a mutex before a critical section and then releases it.

    - Scannig issue of new SCSI devices Hello, I am writing a user application program to scan hundreds of SCSI drives been connected and/or removed. I use IOCTL_SCSI_RESCAN_BUS to force scan (suppose to invalidate the device list in SCSIPort driver) and then IOCTL_SCSI_GET_INQUIRY_DATA to get the new list. However I get the stale data (i.e the device list prior to the drives been connected and/or removed). After I call IOCTL_SCSI_RESCAN_BUS and IOCTL_SCSI_GET_INQUIRY_DATA several loops (each time the number of loops changes), IOCTL_SCSI_GET_INQUIRY_DATA returns the correct list of drives. Using the SCSI Analyzer it has been confirmed that IOCTL_SCSI_RESCAN_BUS send REPORT_LUNS, then several INQUIRY command (the correct data is returned for all the new drives connected). Is there any way to prevent getting the stale device list? Is there a way to force clear the stale device list in the scsiport driver?. This is a major issue for the application program as it does not know the number of loops it has to issue the IOCTLs to get all the new device list.

    - USB enumeration time in a production test environment I seem to recall a discussion thread regarding speeding up recognition/enumeration of new devices. The problem that needs to be solved is that it's taking from 7 to 20 seconds for a new device to become available for communication after power on connection. The folks at our production facility want this to happen more quickly. The port that we will be using can be dedicated to this function. The device VID, PID, and Version will be constant but the USB serial number will probably be changing. My inital reaction is that the amount of time needed for enumeration is determined by how much work the PnP manager has to do to figure out the correct driver. As I mentioned, I seem to remember a similar issue that was on the list, but a search of current articles doesn't seem to turn anything up. Does anyone remember this one?

    - 1394 Raw Mode Addressing And Driver Verifier Hello All... I've been using 1394 raw mode addressing successfully but when I run the driver verfier I get a bug check when accessing the port driver to perform a raw mode io request. My guess this is because I'm using an address that wasn't obtained by using IoGetDeviceObjectPointer( ). I retrieve the port driver address by accessing the bus driver's PortDeviceObject element. As follows.... // Get the port driver object. This is the next to the lowest layer in the driver stack. // The port driver is used to send messages to a node other than the node // for which the lower driver object exists. pDeviceExtension->pPortDeviceObject = ((PNODE_DEVICE_EXTENSION)pDeviceExtension->pStackDeviceObject-> DeviceExtension)->PortDeviceObject; However, I don't know what the symbolic link is for the 1394 port driver. (driver file ohci1394.sys.) The symbolic link for the bus driver is known as \\device\1394BUS0. Does anyone know the symbolic link for the 1394 Port Driver? I need this since it's required as the first parameter in IoGetDeviceObjectPointer( ). Thanks, Scott Tag: Printer folder Left Bar Tag: 65549

    - Newbie! Creating correct inf file Hi, before asking my question I should say that I'm absolutely new to driver programming and worse I don't even have the DDK documentation. However, I have some years experience with Windows development and now want to create a MIDI driver thats sole purpose is to route MIDI messages to my custom application. I have already found the documentation for Installable Drivers in the Win SDK and some code in newsgroups. The code is written for Win 3.11 but I was able to rewrite and compile it under Windows XP. I'm also able to load the driver with the OpenDriver() API. My question: I want other applications let select the driver for their MIDI output device. For this, I assume, I must install the driver. The old Win 3.11 code example comes with an inf file that looks something like this: [disks] 1=. ,"My MIDI driver",disk1 [Installable.Drivers] MyMidiDrv=1:d:\bcb5\music\installableDrivers\MidiDriver1\MyMidiDrv.dll,"MIDI","MIDI",,, However, trying to install this always gives me the error "Installation failed". What could be the cause? Is this inf file at all valid under Win32? I really appreciate any comment/idea!! thanks, Nick Tag: Printer folder Left Bar Tag: 65493

    - printer driver halftoning I have been given the task of adding enhanced halftoning capability to an existing printer driver. The driver sends its output to a thermal transfer barcode printer. This is monochrome device (hence the need for halftoning). I have tried changing the halftoning parameters, such as the GDIINFO HTPatternSize, but this does not seem to affect the output. Ultimately, I am look for a way to let the use choose from any of the HT_PATSIZE_* values and have the driver use these when rendering color images. I just can't seem to get all of the settings lined up just right between the GDIINFO, DEVINFO, DEVHTINFO. I have implemented DrvStretchBlt and I am calling EngStretchBlt with iMode set to HALFTONE. None of this seems to help. Any pointers or suggestions would be welcome. Neal Tag: Printer folder Left Bar Tag: 65477

    - Mirror Driver - Capturing GDI Call information Hi everyone, For a remote desktop type application, I am trying to see if it is feasible to actually grab GDI call information with a mirror driver and send that to the client where it would be drawn. This would result in much less data being transferred over the network over the usual approach of sending pre-drawn JPEG rectangles for changed parts of the screen, I would think. Can anyone point me to some information on how to do this? How would I use this data on the client to redraw the display since it will be coming from kernel-mode on the server? The DDK mirror sample doesn't have enough comments for me to figure this out. Thanks! Aruk Tag: Printer folder Left Bar Tag: 65476

    - is device interface path (DevicePath) persistent ? Is device interface path [ i.e. the DevicePath parameter of the SetupDiOpenDeviceInterface function or DevicePath member of the SP_DEVICE_INTERFACE_DETAIL_DATA structure ] persistent 1) between reboots? I.e. will sequential SetupDi*-style enumerations made in the same Windows session give the same DevicePath for the same device interface? 2) over reboots? i.e. will enumerations before and after reboot give the same DevicePath for the same device interface ? Many thanks! Igor. Tag: Printer folder Left Bar Tag: 65474

    - drive letter from DevicePath / Device handle Should be an easy question I guess ... Suppose, I used SetupDi* functions to get the DevicePath for the device, say CD-ROM drive, and then opened the handle for the device passing this DevicePath to CreateFile. So far, so good. Now, what is the best/recommended way to resolve the drive letter (if any) associated with this device [e.g. E:, F: etc] ? Many thanks! Igor. Tag: Printer folder Left Bar Tag: 65472

    - High Volume Queueing in NDIS MiniportSendPackets I have a deserialized intermediate driver that accepts packets in MiniportSendPackets, queues them, schedules a work item to do some processing on them that has to happen at PASSIVE_LEVEL, and sets their status to NDIS_STATUS_PENDING. The work item completes the packets once it is finished processing. This all works fine in low volume situations, but when I subject my driver to one of the NDIS Test stress tests, I notice the following: - MiniportSendPackets keeps getting called at DISPATCH_LEVEL and queueing the packets; - My work items never get a chance to run and complete the packets; and, - Eventually I run out of buffer descriptors and I have to start setting NDIS_STATUS_FAILURE on the packets in MiniportSendPackets. I don't think there's a way to pause the execution of MiniportSendPackets because it's getting called at DISPATCH_LEVEL. My question is: how can I follow all the rules for MiniportSendPackets in this situation and still give my work items a chance to complete the packets in a high volume situation?

    - NDIS driver Hello: My application involves streaming audio, video, and control data from nodes with embedded ethernet capabilities. Each node will have a video camera and microphone as inputs, and speakers and a video screen as outputs. Each node can transmit audio/video/control data to any other node on the network. The windows PC will be able to stream data to any node, and will be able to receive data streamed from any node. The PC will also be able to monitor and save data being streamed directly from 1 node to another. The nodes will have ethernet PHY/MAC front ends connected to a microcontroller or FPGA to send and receive data, but no high-level capabilities (ie no TCP/IP stack). My question is what sort of network driver I need to write (Windows XP). Is an intermediate NDIS driver the correct choice? Is there a way to simplify the architecture by improving the capabilities of the remote nodes - ie package audio/video/control data as some "standard" format recognized by Windows resulting in simplification or elimination of need for custom device driver? If nodes have full TCP/IP stacks, does this simplify anything? If nodes are just "dumb" MAC addresses that source or sink data without knowledge of any windows high level protocols, does this force the creation of custom network driver? Any suggestions are welcome. Thanks, Doug Tag: Printer folder Left Bar Tag: 65461

    - About SMB client driver ... I am using Microsoft Windows 2003 on a Tyan motherboard which has the Intel ICH5R (7520 chipset). This chipset has an embedded I2C controller and my application needs to do some I2C based device communication, i.e. thermal, drive detection, etc. These are normal I2C communication that I can get done in Linux very well. With Windows I know that some SMB client driver is needed. I can't figure out if there are any SMB client drivers available from Microsoft for Windows 2003 (at some point it will be SAK solution). If there is a driver already available then how do I talk to the driver (i.e. are there documented IOCTL that I can use?). If such a driver is not available then how easy it is to write one? Even if I write one the SMB client driver of mine needs to talk to the SMB class driver but I do not know or did not find any document that explains this. Can somebody please provide me some information on how to get this working. Sincerely appreciate your feedback and help on this one.

    - Help in analyzing crash dump files When I get a BSOD, I use Visual SOFTICE and a Kernel memory dump to try and trace the error. If one of my driver's function is in the stack trace, I can goto its source and try to find the error. My problem starts when I don't see my driver in the stack trace, and even when I disassemble "Parameter 4: Address of instruction executing" I can't see any of my driver's function. Any way I can get more informant from the dump? Does WinDbg can be more helpful in analyzing dump files ? Any way to know if the win32 user mode app caused the crash? (Then I need to use a complete memory dump?) Any other tips on debugging BSODs? Thanks Tag: Printer folder Left Bar Tag: 65456

    - Override excel's printing dpi setting This question has been asked before, but not answered. So here goes again: I need to programmatically print excel documents based on the printer's settings (essentially the dpi). However, for excel documents, they have their own print settings in Page Setup. When printing programmatically, these settings override the printer's default settings. Any ways to change the document's settings, or to override these settings to use the printer's, or even to intercept the print job to change them? Thanks! Tag: Printer folder Left Bar Tag: 65453

    - DPC/ISR synchronization (windows ce) I haven't had a lot of response in the platform builder newsgroups, so I'll try here. In Windows CE 4.1, I had no problem with a NDIS ISR (miniportISR) interrupting the DPC(MiniportHandleInterrupt). In upgrading to Windows CE 5.0, I'm seeing that the ISR is getting held off by the DPC. I've tried serialized/deserialized. I've verified that the interrupt is not disabled in the kernel and can see with independent means that kernel is seeing the interrupt and setting the interrupt event in time with the hardware, but the ISR waits until the DPC finishes until it is run. Does anyone have visibility into what has changed between the CE 4.x and 5.x NDIS implementation ? The driver registers as an NDIS 5.0 miniport. Tag: Printer folder Left Bar Tag: 65444

    - HID mouse filter (aka firefly) question Greetings, I have a question about the DDK firefly example. It's supposed to show how to implement a filter driver for a MS optical mouse device. My question is, how are HID mouse events actually intercepted, identified, and filtered relative to the firefly example? I'm kinda new at device driver programming, but I already understand (to some extent) the other filter drivers (moufiltr and kbfiltr) in the DDK, to the point that I've successfully modified, rebuilt, and loaded those. Now I want to do the same with the firefly example (really for all HID mice and keyboards), but there don't seem to be enough clues in the example. Can somebody help me connect the missing dots?

Hi!
In windows XP in Printer folder there is a bar in left. In that bar there
is a section called "See also". When user selects any printer then in "See
Also" section it shows manufacturers Url.

Now my problem is I want to add more URLs in that section. 1 URL can be
added by using printer inf. OEM URL. but how to add more URLs in that section?

What I can think of is that some shell extension needs to be written? but I
have no idea about this...

Any help would be appreciated.

Thanks
Naveen
