Hi, In my printer driver(user-mode), I am trying to get a character width in logical units, same as by calling GetCharABCWidths function.

Can someone tell me it is a correct way? And how can i get the corrert result? Plz help me, I am need of these truely very urgent to me. Thanks! Tag: Opening disks in a driver Tag: 73754

    - Udp sending performance in Gbit Ethernet Hello, This topic has been previously discussed in win32.programmer.networks, but no clear solution has been found. It seems that when sending UDP packets at maximum speed, the throughput of the sending drops significantly when the payload size is increased from 1024 to 1025 bytes. This seems to be connected to the NIC interrupts in some way, it seems like that 1024-byte packets can be sent at full rate, but 1025 byte packets only once per interrupt (and per sending application). I made a web page of the situation so far, and it is located at: http://www.kolumbus.fi/juha.lemmetti/Udp.html If you have explanation or work-around, please reply to this post or to me (e-mail is on the web page). Greetings, Juha Tag: Opening disks in a driver Tag: 73751

    - Multi-interface USB Device : how to get a endpoint handle ? Greetings, I am writing a lower filter driver for a USB device, and I need to write some data to it. How can I get a pipe handle to an endpoint ? In most of cases, you can get them while choosing a configuration, by calling USBD_CreateConfigurationRequestEx. The problem is that my device has one configuration, several interfaces, and my filter driver is installed for only one of them. So I can't use USBD_CreateConfigurationRequestEx. Is there another way ? Tag: Opening disks in a driver Tag: 73702

    - How to implement the pending mechanism between KM and UM hi all, I am trying to implement a packet capture driver in DDK. Unlike netmointor, I hope the driver could capture the packet to application real-time. So I implement an event, generated by driver, to indicate the application to get the captured packet from driver. In order to reduce the overhead in keeping the captured packets, I use a buffer pool in driver to contained the packet temporarily before application read them. However, if the pool is full in the heavy traffic cases, the extra packet will lose. I find NDIS uses a PENDING state in its receive path. How can I implement the similar approach to cover the problem. Thanks! -Liang Tag: Opening disks in a driver Tag: 73662

    - Update PCI Latency Hi, I'd like to know how can I change the current PCI Device Latency of connected devices? I experience that most of modern graphic adapters have a very high pci latency value which causes problems on other PCI devices like USB chipsets etc. What I want to do is to offer an option to reduce the PCI latency of such devices. Now my questions: - How can I do this? I found some structures and API calls that mention these things, but I wasn't able to build me a proof-of-concept. - Is that propery way to manage this at all or should this be a task for the graphic adapter manufactureres (all of them)? The thing is that a lot of customers complain about instability of their PCs concerning high bandwidth/low-latency USB devices and quite often (more than we expected) the solution seems to be to decrease the PCI latency of the graphics adapter from 255 to 128 or 96. I experienced this with some of my firewire devices, too. IMHO I think this is not something one should leave to the end user. thanks for any advice in this doc Tag: Opening disks in a driver Tag: 73654

    - SetupDiBuildDriverInfoList problem with USB bluetooth? Hi, I need ti enumerate all USB bluetooth dongle with a particular VID/PID. We have our usb driver (not signed) and we also use the widcomm bluetooth stack. The bluetooth dongles are also compatible with the Windows XP SP2 stack. The main problem is: -I try to retrieve all the compatible driver for this dongle using SetupDiBuildDriverInfoList() -> it works. - Then I try to get the currently installed driver (by changing the device install params and calling again SetupDiBuildDriverInfoList()) -> it works only the first time. After that it says "no more items" I've checked with the Hardware manager and I've found that the Bluetooth device's icon changed and displays the "WinXP bluetooth icon" -> But the widcomm or our driver is still loaded and working! If I re-install the drivers, the icon goes back to the normal one. But as soon as I call again SetupDiBuildDriverInfoList() on this device, the icon change back to the WinXP bluetooth icon! This is not the case on a bluetooth device with a VID/PID not compatible with the WinXP stack. How can I avoid this problem? To reproduce this problem, it's simple: - Install a bluetooth device compatible with the WinXP stack using a other bluetooth stack (Widcomm for example) - Check the icon with the Hardware manager. - call SetupDiBuildDriverInfoList() on this device using default dev_install_params. - Refresh the hardware Manager and you should see the device with a new icon!

    - Problem! Interrupt service routine not executing after some interrupts generation Hi Everybody, Our PCMCIA 16 bit PC card(with WDM driver) is generating Interrupts properly and in the Interrupt service routine we are servicing immediately. If we does not service the interrupt then our device will stop generating interrupts. After some time Even though our device generated interrupt but ISR is not invoking. In this case we are not able service the interrupt becase ISR not executed. Then our device will stop generating interrupts. This kind of problem is coming when I move mouse or if i use keyboard. In IoConnectInterrupt routine Iam passing TRUE for Sharable interrupt parameter. What could be the problem? Is it a sharable interrupts handling problem? Please guide me. Thanks in Advance. Mahinder.

Any pointers will be greatly appreciated. Thanks in advance, -- RA Tag: Opening disks in a driver Tag: 73607

    - Printer Driver -- UniDriver pluginUI -- "DOCUMENT" Property Sheet Pages -- Questions Printer Driver -- UniDriver pluginUI -- "DOCUMENT" Property Sheet Pages -- Questions I am using function "IOemUI::DocumentPropertySheets". I am trying to add/remove "page dialogs" under "case PROPSHEETUI_REASON_INIT". I am NOT concerned at all about "OPTITEMS". I can successfully add my CUSTOM page dialogs using CPSFUNC_ADD_PROPSHEETPAGE, as shown in the "UI Plugin" example. Is this the correct way to add my custom pages? Should I be using CPSFUNC_ADD_PCOMPROPSHEETUI instead? Also, I would like to remove the two page dialogs that seem to show up automatically; page dialogs with names "Layout" and "Paper/Quality". I intend to replace them with custom pages that do something similar. The device(printer) property sheet page dialogs seem to work fine; I use function "IOemUI::DevicePropertySheets" for this case. Any ideas? Thanks, Rudy Tag: Opening disks in a driver Tag: 73596

    - Unsigned Virtual Driver - Multiple Instances Hi, I have a unique virtual NDIS Miniport driver which essentially creates virtual NICs in the sytem. Because of a no of reasons i will not be able to get this driver signed. This poses a problem in driver installation. Firstly i know that i will get the Unsinged Driver warning popup message (if the user has behaviour set to warn). My problem is that i want multiple virtual NICs that can come and go at any time. ( i have a virtual bus driver that creates PDOs whenever i want). Now if i have the NIC installed for 1 instance, when the 2nd NIC shows up Windows again asks where to install the drivers from. Why is this happening? I already have it installed and the 2nd instance shall just use the driver being used for 1st instance. This happens even if i turn the setting to ignore WHQL signatures. Also during installation the whole N/W stack for the 1st instance is tore down and driver is unloaded and reloaded (i guess since it copies a new driver file - happens even if i refuse to copy driver file). Basically i want the instances of the NIC to some and go silently without asking for installation again and again. (Although once i install 3 instances, they come and go silently but the 4th one again asks for driver). I cant go thru manual installation of 16 Nics in the begninning.I Dont even know how many will be enogh. Can a finite no of instances be installed at inital set up without even creating PODs for each one of them? Is it not possible to acheive with Unsigned Drivers or am i mising something. do i need to write a Co-installer, or somethig like that. thanks Pankaj Tag: Opening disks in a driver Tag: 73588

    - ZwCreateSection Hi All, I used ZwCreateSection() to create a section object in a kernel mode driver and tried to open the section object using CreateFileMapping() in windows. The problem is that both the driver as well as application will be updating the shared memory. So, when I tried to open the shared memory with FILE_MAP_WRITE specified in OpenFileMapping(), it returns win32 error code 5 (access denied). It succeeds with the FILE_MAP_READ access. If I use ZwClose() in the driver to close the section handle, I am able to use in the user-mode application. Is there any way I can specify in the kernel mode driver to make it possible to the user mode application too to write to the shared memory? I may be missing some flags in ZwCreateSection() or ZwMapViewOfSection() or InitializeObjectAttributes()? Besides writing to same memory from user-mode and kernel-mode in such scenario can result in any problem ( I suspect)? Tag: Opening disks in a driver Tag: 73585

    - Filtering disk IO when Windows hibernates Dear gurus, Could you advise how disk IO requests Windows 2000/XP sends during hibernate (or crash file dump) process can be filtered? In more detail, the problem is in the following. We work on software that transparently encrypts sectors on physical disks. My disk IO filtering driver works fine except the moment when Windows hibernates or writes crash dump file to disk. At that moment Windows does not use a regular well-documented stack of layered disk drivers. Instead, the operating system calls disk miniport driver directly. (Probably it would be more correctly to say - after sending IOCTL_SCSI_GET_DUMP_POINTERS Windows loads a separate copy of the driver and uses it for writing sectors.) As a result, our filtering driver cannot filter and encrypt the sectors Windows writes during the hibernation process. If someone knows how to filter these disk IO requests, the advice would be greately appreciated. Best regards, Sergey (I've read several topics on the matter in newsgroups, but could not find some concrete answer. As MSDN subscribers probably we should contact Microsoft, but is it really necessary and may help?) Tag: Opening disks in a driver Tag: 73583

    - problem with mixed bpp system In a multi-display system where the primary display is in 32-bit mode and all other displays are in 8-bit gray mode (non-palettized, linear), the display driver provides DrvBitBlt that will convert 32/24-bit source to 8-bit destination using NTSC weighting. Most drawing to the displays goes, as expected, through DrvBitBlt. However, not all code path seemed to go through that. Specifically, clicking the right mouse button on an 8-bit display and then selecting "Refresh" leaves a rectangular region that is rendered differently, using Windows' own way of converting 32/24-bit to 8-bit. Similar artifacts show up when pop-up descriptions pop down in the main file area of the windows explorer. Interestingly, the pop-up descriptions popping up for items on the left area (system Tasks, Other Places), do not leave any artifacts. How can one avoid those artifacts? Is there a way to provide this NTSC weighting to Windows to be used for all 32/24-bit to 8-bit conversions (XlatOBJ, PalOBJ)? Tag: Opening disks in a driver Tag: 73571

    - 8 bit display driver color conversion In the display driver/miniport, how can I make the OS call my DrvBitBlt with the 32/24-bpp source and let me convert it to the 8-bpp destination? Windows likes to convert the 32/24-bpp source to an 8-bpp one and then call my DrvBltBlt hook. Any ideas? Thanks Tag: Opening disks in a driver Tag: 73568

    - WPP tracing I am writing a file system filter driver. This is one binary driver build in windows 2000 enviorment and supports XP as well as 2003. This driver does lot of initialization activity in DriverEntry routine including creating device object. I was trying to use WPP tracing method, I refered the following article at OSR website http://www.osronline.com/article.cfm?article=376 . I could make tracing work but I would never get tracing messages in driver entry Is this a limit for windows 2000 driver. Thanks Ashish Tag: Opening disks in a driver Tag: 73563

    - wdfcoinstaller01000.dll hangs. Hi, in the process of installing a usb filter driver, the hardware update wizard will display "copy wdfCoinstaller01000.dll to system32 directory" message. Somehow for my case, the system stuck there and the copy process never end. And system is still functional for other things. Do anyone know how that can happen? Thanks. Al.

    - Smartcard PC/SC IFD handler I need to implement a solution to have the Windows XP operating system accessing a smart card device. After researching the MSDN, I got to the point where I have to provide an IFD handler so that the Windows Resource Manager can access the smart card device, and that IFD handler is basically a Windows device driver. The smart card vendor provided a DLL that contains an API to access all the device functionalities, so I'd like to develop that IFD handler on top of the smart card vendor API. After starting to use the Windows DDK, I realized that the vendor API header file is not compatible with the DDK include files if compiling for kernel mode driver, but it is compilable for user mode driver. The question is: can I have a user mode driver as an IFD handler? Tag: Opening disks in a driver Tag: 73559

Greetings,

I have a driver where I need to open some number of disks (i.e.
HarddiskVolume5) and then be able to do asynchonous I/O to them ( aka, a
simple volume manager). I've looked at IoAttachDevicetoDeviceStack but do
not think this is the way to go...
Can someone point me in the right direction?

Thanks.
