    - 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: out of the device driver newsgroup 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: out of the device driver newsgroup 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: out of the device driver newsgroup 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: out of the device driver newsgroup 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: out of the device driver newsgroup 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. Regards SG -- SG, Device Driver writer Tag: out of the device driver newsgroup Tag: 65458

    - 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: out of the device driver newsgroup 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!

    - 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: out of the device driver newsgroup 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?

    - Kernal or application thread - Help Hi Guys I have a windows application and device driver using a piece of data acquisition hardware. When the data has been acquired I use the device driver to read back the data. Its read back byte by byte and there is a lot to read back. At the moment I don't have any threads operating so when the device driver is reading back the data the User interface is locked out. So what I'm going to do is create a thread that operates in the background always waiting for the data ready signal and then reading the data back when its available. It would have lower priority than the User Interface thread and so should not effect its operation. My question is this. Should I create a thread in the kernel i.e. created by the device driver, Or should I create a thread at the application level which owns the device driver(i.e. opens it communicates with it etc.)? Creating a thread in the device driver is easier for me given the current software architecture. If I change, to create a new application level thread then all existing communication between the User Interface thread and the device driver would have to be modified to go to, and then through the new thread. So Ideally I want to create a new thread in the Kernel. But will it operate at a lower priority than the User Interface thread and therefor allow it priority. All help appreciated.

    - Use GetPrinterData to GetPrinterDataFromPort to get printer status Trying to write a language monitor for a printer to retrieve printer status, but having some trouble connecting the dots. There does not seem to be much info on this subject. Through reading other threads and info on the MSDN site I understand that the API GetPrinterData retrieves printer config data from the registry, but if the data is not in the registry it will call GetPrinterDataFromPort in the language monitor, which will communicate with the printer with WriteCommand and read back the results in the UstatusThread with ReadCommand. I can retreive an existing registry key with GetPrinterData successfully, but a non-existing key will return 0 bytes needed and does not seem to call the language monitors PJLMonGetPrinterDataFromPort. I have a debug statement with OutputDebugString here that never gets called. What do I need to do in order for an application to retrieve printer status directly from the printer? Is this the preferred method? Do I have to make use of SetPrinterData to store the result or trigger the call to GetPrinterData to make the call the the language monitor? If there is a more appropriate thread for this question, please let me know. Assistance with this would be much appreciated. Thankyou Tag: out of the device driver newsgroup Tag: 65437

    - Install a filter driver automatcally Hi everyone, DDK sample Firefly shows how to install a mouse filter driver on a USB mouse, but it requires manual installation. A user has to find out his/her mouse device object (sometimes appears as HID compliant mouse) in Device Manager and take the "Update Driver" route to install it. Is it possible to install such a filter driver between mouhid.sys and mouclass.sys (so it filters all USB mice but not other PS/2, serial, i.e., not a classwide filter) aautomatically with a SETUP.exe or the similar? Is there any example to create SETUP.exe for automatic installation? Thanks in advance, Liang Fu Tag: out of the device driver newsgroup Tag: 65425

    - Network mechanism in windows Hi all, I have following problem. Using NDIS IM, I have discovered that after plugging cable into NIC card (e.g. associated with ip 192.168.10.1), windows send throught it ARP request (filled with Sender IP = 192.168.10.1 and Target IP = 192.168.10.1), which is then indicated as received (again in my NDIS IM). It occures even if translation for the IP is included in ARP table, so I suppose that this is done as some kind of testing accessibility of network.

    - PAE question about memory access Hello, I have some questions related to the use of PAE for access to memory beyond 4G in 32-bit Windows drivers. I'm trying to understand how a PCI device which supports dual address cycles works in conjunction with a device driver running on a system with PAE enabled. As I understand it any memory that the system provides can be either above or below the 4G mark. If a driver calls IoGetDmaAdapter with Dma32BitAddresses set to TRUE (and Dma64bitAddresses set to FALSE), does this mean that when AllocateCommonBuffer is called that it will only give memory which is physically below 4G? Or does it mean that the memory can be anywhere, but the "logical" address it returns will always be a 32-bit quantity? Or is there some other interpretation? In my case, the device only wants to receive 32-bit host memory addresses to access, but we do want the device to be able take advantage of the upper memory, if possible. Also, if for some reason we did want to restrict the memory for this device to the lower 4G of memory, is there a way to specify it? We might want to support some device types which can support DAC and some which do not in the same driver at the same time. Thanks, Nathan Tag: out of the device driver newsgroup Tag: 65387

Is there a way to get a crash dump even by adding devices or/and developping device drivers? i assume a pagefile must be created on a disk somewhere?

    - NDIS passthru: signal event We are programming in a driver (NDIS passthru) environment and would like to know if there is an efficient way to signal the "outer world" about an event that happened in the driver. We know that we could use DeviceIoControl, which is good to supply data from "outside" to the driver and this routine also works in the opposite direction. However, you would have to "poll" the driver every now and then which is not really a nice way of obtaining data from a driver, is it? There must be a better, direct way of signaling the normal environment in a driver, but so far we havn't found anything. Any suggestions (, if possible with sample code)?

    - Missing VSS SDK files + GatherWriterMetadata problem The BETest example from the 7.1 VSS SDK requires some files that appear to be missing from the SDK, e.g. vs_assert.cpp, vs_assert.hxx, vs_trace.cpp, vs_trace.hxx, vs_hash.hxx, vs_hash.cpp and others. Also the include path in the "sources" file is incorrect and refers to a non-existent library: tracing.lib. Where can I find the missing files?

    - Print bitmaps from MSPaint Hi I am developing a virtual printer driver starting from the MSPLOT DDK sample. The driver uses a device managed surface and there are implemented DrvCopyBits, DrvBitBlt and also other painting hooks. When printing from MSPaint, DrvCopyBits is called, but the problem is that I receive very large bitmaps, even if the bitmap opened in MSPaint is small. For instance, in MSPaint I have a bitmap filled with one color and only one line drawn with another color. I would expect to receive in DrvCopyBits a source surface with a 4bpp bitmap, but I receive a 24bpp bitmap. You can see in this bitmap many other colors, like a translation between the two colors used in the MSPaint bitmap. Why is this happening? Here are some settings made in driver: - the dither format in the DEVINFO is set for BMF_24BPP, and the DrvDitherColor is not implemented. - the default pallete is created with EngCreatePalette(PAL_BGR, 0, 0, 0, 0, 0) - the halftone in the GDIINFO is set to HT_FORMAT_24BPP Are there any other settings that could generate this behavior?

    - ACPI.sys gets into endless loop reading temperature to appologize right away; i've started to write drivers w/ RT11, VMS etc, but then I got too old to do this stuff; now I find myself back in Win XP w/out clue... I found out: sytem proc [4] handle 64h jumps into acpi.sys+10b10h when my CPU P4 2.4 Ghz Northwood gets around 75C. Unfortunately it starts to consume continuously 50% of CPU power (Hyperthread active) and it does not go to sleep even if the temp. goes down. Amazingly, when I start e.g. Sandra or any other program which reads board and CPU temp, the system proc. goes back to eventually running 1-2% every now and then as before. I AM NOT TALKING ABOUT THE SYSTEM IDLE PROC. Award Bios 6 PG, EPOX Mob 4PDA2+, Win XP SR2 P4 2.4 Ghz Hyperth.active I assume there is an event telling that the CPU gets hot; ACPI gets involved and ACPI can than either not read the correct value from the BIOS or cannot find any release criteria to understand that the temp event has gone away. Could somebody illuminate my ignorance: which event triggers the system proc [4] handle 64h to run can somebody provide the sources of acpi.sys latest build where can I find documentation, how acpi gets motherboard values for temperature; I found a lot about power management, but not about temp. sorry to bother hk.

    - Does BDA DVB-T minidriver have better performance than non-BDA one? Hi all, I've done some research about the BDA architecture. My purpose is to develope a DVB-T BDA driver. As I known, Microsoft constructs BDA architecture to optimize the performance. But I wonder if it could optimize the DVB-T performance based on the following reasons, 1. The transform filter is a user mode Mpeg2 decoder, so it can't reduce the system job to copy data from kernal mode to user mode. 2. It seems to be no BDA Mpeg2 decoder, so it can't do the way as BDA transform flter does. Is my understanding correct? Could anyone give me some explaination if any wrong in my above mention?

    - DrvQueryFontTree fails with Splwow64.exe OS: Windows XP Professional x64 Version 2003 Service Pack 1 DDK: Windows DDK 3790.1830 Case: Printing from a 32-bit application DrvQueryFontTree returns a pointer to an FD_GLLYPHSET structure. After that ntdll.dll fails. Following is the call stack information: â??ntdll.dll!RtlCopyMemory () + 0xb0 bytesâ?? When the application that prints is a 64-bit application, there is no failure even though the content of â??FD_GLLYPHSETâ?? structure seems to be identical with the one from printing from 32-bit application.

    - Acquiring a mutex in DPC Hy All, In DDK doc, I can read that KeWaitForSingleObject can be called at DISPATCH_LEVEL if timeout is set to 0. The fact is I use this to wait for and acquire a mutex inside DPCs (either comming from a timer or an interruption from hardware). But I can also read in KeReleaseMutex that a mutex should ALWAYS be released by the thread holding it. My questions are: - Can I acquire the mutex in a DPC called by an interuption and then release it when the DPC is called by a later interruption? - Can I acquire the mutex in a DPC called by an interuption and then release it in ANOTHER DPC called by a timer In other means, from the mutex holding / releasing point of view, are the DPC calls considered to be done by the same "system" "thread". Many thanks in advance, Francois. Tag: out of the device driver newsgroup Tag: 65278

    - Exception Handling in the kernel Hi all. I have never used exception handling in driver code, but I recall that in NT4 you could use it in code called by an application, so read/write/deviceiocontrol dispatch code could contain it. I was wondering if the situation had changed at all and was looking for a definitive statement on what exception handling can be used, where it can be used, and at what level/priority it can be used. Not having found an answer on line, or in the DDK, I was wondering if anyone can enlighten me? Tag: out of the device driver newsgroup Tag: 65276
