    - hyperthreading prevents printer driver installation Hi, I'm having a problem with our printer driver in Windows XP Professional when hyperthreading is turned on in the BIOS. It attempts to install but looking at the error log it says that Windows deletes the printer afterwards. The driver has a IPrintOemUI COM interface to add a tab to the property pages. I built this driver using an old Windows 2000 DDK. Should I be revising it? Tag: Fonts used in EMF Spool file Tag: 83242

    - NDIS driver install by snetcfg.exe help! Hi everyone, I write a NDIS driver and use "Local area network property" to install driver, and it 100% success. If I used "snetcfg.exe" for programatical install my NDIS driver at the computer logon then I get blue screen randomly, I think about 70% success. For cases that success, Device Manger->Network adapter showed: -Network adapters --Intel(R) PRO/100 S Dual Port Server Adapter --Intel(R) PRO/100 S Dual Port Server Adapter - My Sample Virtual adapter --Intel(R) PRO/100 S Dual Port Server Adapter #2 --Intel(R) PRO/100 S Dual Port Server Adapter #2 - My Sample Virtual adapter Everytime the installation failed it give me a Blue Screen and automaticly reboot the node. Then it kicked off the snetcfg.exe to install again. I checked in the Device Manager->Network Adapters showed: -Network adapters --My Sample Virtual adapter (extra stand alone,I think this is causing blue screen) --Intel(R) PRO/100 S Dual Port Server Adapter --Intel(R) PRO/100 S Dual Port Server Adapter - My Sample Virtual adapter --Intel(R) PRO/100 S Dual Port Server Adapter #2 --Intel(R) PRO/100 S Dual Port Server Adapter #2 - My Sample Virtual adapter My guess is timing, when snetcfg.exe start install and the network adapters are there but not fully functioning/binding yet. and when snetcfg install it couldn't find the adapter to bind and it just install the Ndis driver as a stand alone network adapter. Please correct me if I'm wrong... My question is: how do I check if network support is ready/fully functioning inorder for me to install 100% sucess. OR is there any other hints/method for me to avoid the blue screen and also the driver work properly by using snetcfg.exe to install. Many many thanks for any help! ttan Tag: Fonts used in EMF Spool file Tag: 83239

    - x64 intrinsic __readmsr and __writemsr Hi, I would like to know if there is any change in the implementation of these functions on Windows server 2001 sp1 ddk build 1830. I was using these functions in driver interrupt routine with ddk build 1069. When I use new ddk compiler, I see driver binary size significantly increase (~2k), and driver gets a blue screen if the interrupt routine is enabled, which practically do only a msr write function. This msr write operation was safe with ddk build 1069. Any input? Thank you, RJ Tag: Fonts used in EMF Spool file Tag: 83238

    - How much knowledge of OS is required using WDF? Hello, everyone. I¡¯m an undergraduate student who is looking for a job. Because I don't know anyone who writes device driver, I really want to listen to your opinion. When I was reading the book Windows Internals, I¡¯ve realized that a lot of sections are targeted to device driver developers. Because I enjoyed the book, I¡¯m considering getting a job that I can learn about Device Driver development. However I think that WDF is trying to isolate device driver from the operating system. I¡¯m afraid that I may loose interest because of that. I want to know about, How much work will be done using UMDF? (not by category of technology but proportion of jobs) And how much and concrete knowledge about Windows kernel is needed when using KMDF comparing to WDM? Thanks in advance.

    - Webcam "Hazy" effect on USB1.1 mode My webcam driver is based on "usbintel" sample in DDK src\wdm\videocap folder. We changed it to support 64-bit system but encountered a problem when connect the device to USB1.1 port (via a USB1.1 hub which connect to a USB2.0 port on motherboard) on 64-bit XP. The issue is : preview effect is hazy, it's like cover the preview window by using a gray semitransparent cloth. I have no idea how come that happened? Is it related to the sensor settings or USB chip control? Any suggestion would be greatly appreciated~ Barry Tag: Fonts used in EMF Spool file Tag: 83201

    - Suppress command window wile using IExpress wizard Hi all, I'm using IExpress wizard to create a self extracting driver package. I use a command-line script to create some directories in the extraction path and copy some files into them. I'm using DPInst to install the driver files onto Vista systems. My questions are; 1. How I can suppress or at least minimize the ugly command window that pops up when the command-line script runs? 2. Some of the buttons on the DPInst screens seem to be redundant... such as the Finish and Cancel buttons on the finish page seem to do the same thing. How can I get rid of the redundant buttons on the DPInst screens? Thanks in advance, Shaji. Tag: Fonts used in EMF Spool file Tag: 83196

    - Interfacing to Com port driver I am attempting to interface to a piece of equipment which provides serial port emulation via its driver for USB. When it is plugged into different USB ports, it appears at different com port addresses - i.e. COM8: or COM12: (on my machine). I have two specific quistions: 1) How do I open a COM port greater than COM9:? When I try to use the recommended procedure (open as a file), it fails if the COM port number is greater than 9. 2) How do I find which COM port number the device is connected to? It manifests as a modem, and has a specific device name which I can see in Hardware Manager. If I examine the advanced port properties, I can see which COM port number it has assigned. I need to find the device by name (or see if it's not there). How do I do this? I am using Visual Studio 2005 and writing in ANSI C.

    - Windows Vista Printer Driver and Printer Name Hello all, I've developed a user mode printer driver. Until Windows Vista it never had any problem. In Vista, when installing from remote server, the printer name that gets into DrvPrinterEvent, with PRINTER_EVENT_INITIALIZE, it's something like this "\\CSR|ServerName\{94718C2F-E998-90E2-2CA0E49A1C12}. What does this printer name means? I've also noticed that there are additional registry keys under "HKLM\Software\Microsoft\Windows NT\Print\Providers\Client Side Rendering Print Provider\Servers\ServerName\Printers\{94718C2F-E998-90E2-2CA0E49A1C12}" What Keys are these ones?? The driver uses my own Language Monitor, which will write specific data under PrinterDriverData, normally it was written under HKLM\System\CurrentControlSet\Print...." but now where should it be written? Strange it's the name that get's into DrvPrinterEvent! it should be something like \\ServerName\\Printer Name" !! And PRINTER_EVENT_INITIALIZE gets called like 6 times in a row, and when I try to print nothing happens. No StartDoc, no closeport, nothing!!! It worked ok two times, and at this time I've noticed that local registry settings were the same as in Server registry. Help me please!! Tag: Fonts used in EMF Spool file Tag: 83181

    - IRP_MJ_SCSI Hi All, I need to write a bus driver for a customer storage controller chip. I cannot use the SCSIPORT model as the enumeration of the devices is very specific and I feel writing a bus driver will provide me the most flexibility to do this.

    - How to inhibit Enabling of I/O Resource Hi everybody, I have a PCI device which is able to export its Control/Status Register space (4 KB in size) to both Memory and I/O Address Space. However, due to the fact that I/O resources requirements are reported in a single PCI BAR (which in fact is a PCI spec violation), I get a Code 12 error in Device Manager ("The device cannot find enough free resources that it can use"). In this case the last function code the PNP Manager sends is IRP_MN_FILTER_RESOURCE_REQUIREMENTS. The resource requirements list reads as follows: Resource Requirements: Number of Lists: 1 List 0: Descriptors: 7 Desc 0: - Option: preferred - Type: CmResourceTypeMemory Length : 1000 Alignmt : 00000001 Min.Addr: 00000000.c0000000 Max.Addr: 00000000.c0000000 Desc 1: - Option: alternative - Type: CmResourceTypeMemory Length : 1000 Alignmt : 00001000 Min.Addr: 00000000.00000000 Max.Addr: 00000000.00000000 Desc 2: - Option: required - Type: 0x81 - NAK Desc 3: - Option: preferred - Type: CmResourceTypePort Length : 1000 Alignmt : 00000001 Min.Addr: 00000000.0000c000 Max.Addr: 00000000.0000cfff Desc 4: - Option: alternative - Type: CmResourceTypePort Length : 1000 Alignmt : 00001000 Min.Addr: 00000000.00000000 Max.Addr: 00000000.ffffffff Desc 5: - Option: required - Type: 0x81 - NAK Desc 6: - Option: required - Type: CmResourceTypeInterrupt Min.Vector: 24 Max.Vector: 24 Filtering the above list in removing descriptors 3 through 5 from the list helps: I get an IRP_MN_START_DEVICE and resources look okay in Device Manager (no I/O address range is assigned). However, if I inspect the PCI config space of the device I see the I/O Space bit in the Command Register of PCI Configuration Space enabled. This happens even if the the I/O Space comes up disabled by BIOS. To be very clear at this point: - if there is no driver registered for the device, the I/O Space bit is left unchanged - if there is a driver registered but disabled the bit also is left unchanged - if the driver is enabled, then I/O decode is enabled (even if I tell the system I do not want/need I/O ports) How can I instruct Windows XP to leave the I/O resource disabled?

    - IoCreateDevice before or after IoInvalidateDeviceRelations I'm back-porting an XP WDM/PNP bus driver to W98SE (don't ask why!) and it seems that under 98 I must create a PDO for a newly-arrived device before I call IoInvalidateDeviceRelations, otherwise the driver does not get a following IRP_MN_QUERY_DEVICE_RELATIONS. Under XP the original driver was Invalidating the relations, then creating the PDO during the consequent IRP_MN_QUERY_DEVICE_RELATIONS handling. Is either ordering mandatory?

    - Serial Port Driver Hi! I want to write driver for serial port (COM), but I don't want support standard functions. For me that port has 2 outputs, 4 inputs and 1 interrupt source. Unfortunatelly I cannot "reserve" I/O ports and interrupt vector (IoReportResourceUsage fails) because standard driver has that resources for its own. When I turn off that serial port in BIOS, IoReportResourceUsage succeed, but writing/reading to/from output/input lines has no effect. Please for help, how to "disconnect" standard driver from one of serial ports (COM1 or COM2 - maybe another if exist) and "connect" to that port with my driver. Of cource my driver cannot figure as serial port on Windows' hardware list. Thanks for any suggestions. Best Regards. Tag: Fonts used in EMF Spool file Tag: 83159

    - IRP_MJ_READ asynchronous completion Hi, I am writing a driver for a device, which offers several interfaces - one of it is a virtual serial port. Within DispatchRead (for IRP_MJ_READ) I did as I read and thought that's correct, i.e. mark the irp pending, set a cancel routine, que it, and returned pending. I wrote a simple Win32 test program, which opened the port for overlapped IO and got the data back (if any available) with GetOverlappedResult. But the status returned by a call to GetLastError was still ERROR_IO_PENDING. When used with Microsoft Hyperterminal it seems that Hyperterminal did not get the information, that the IRP was completed at all. Thus I disabled all other interfaces and minimized my DispatchRead to the code below. It doesn't make much sense to mark the irp pending in that way but according the docs and info found on the web it should be allowed and working. IoMarkIrpPending(Irp); *((BYTE *)Irp->AssociatedIrp.SystemBuffer) = 'a'; Irp->IoStatus.Information = 1; Irp->IoStatus.Status = STATUS_SUCCESS; IoCompleteRequest(Irp, IO_SERIAL_INCREMENT); return (STATUS_PENDING); Still the same result. My Win32 program gets the data but does not get correct status information via GetLasterror and Hyperterminal does not recognize that the irp has been completed. Any idea what I do wrong or where I could have messed up my driver? Many thanks Werner Tag: Fonts used in EMF Spool file Tag: 83155

    - Serial Port Confusion I'm new to Serial communication, what I'm confused about is since data is being transmitted serially, should there be a clock signal as well for synchroisation. The output is a voltage for 0 or 1, how will the receiving device interpret this information without a clock? Can anyone guide me to some simple introductory material that can get me started with serial ports, I searched around but most of the articles was too much for me. I know C#/VB.NET and found articles that show me how to communicate serially but I need to know the exact working of a serial port. Thanks & Regards, Joel Tag: Fonts used in EMF Spool file Tag: 83147

    - NdisMEthIndicateReceive - no reaction Hi, I am developing application to encypt / decrypt TCP/IP packets data. I am using the PassThru driver extended by Thomas F. Divine (part 2 of his article). I change packet data outside the driver (in the application) so after decryption I want to indicate packet up. As a MiniportReceiveContext I use NULL, becouse I don't know where I could take it from (I thought that it is not necessary). My problem is very simple - after invoking appropriate ioctl code nothing happens. I used Ethereal to monitor packets and I can't see any of my packets (I hope I am right, that Ethereal looks above NDIS IM drivers). Please look at this little piece of code and tell me what the problem could be. Is it that MiniportReceiveContext or maybe something else. I use DbgView so I know that everything was invoked as I wanted. FltDevIoControl(){ (...) ioBuffer = pIrp->AssociatedIrp.SystemBuffer; inputBufferLength = pIrpSp->Parameters.DeviceIoControl.InputBufferLength; (...) case IOCTL_PTUSERIO_SET_INCOMING_PACKET_DATA: PUCHAR packetBuffer = NULL; UINT headerLen = 14; UINT payloadLen = inputBufferLength - headerLen; NdisAllocateMemoryWithTag(&packetBuffer, inputBufferLength, TAG ); NdisMoveMemory(packetBuffer, ioBuffer, inputBufferLength ); NdisMEthIndicateReceive( pAdapt->MiniportHandle, NULL, packetBuffer, headerLen, &packetBuffer[14], payloadLen, inputBufferLength ); break; } Thanks a lot in advance.

    - USB driver does not start after computer restart Hi everyone I am having some problems with an USB device supplied by our vendor. It comes with a standard .inf & .sys file. The first problem: even the driver can be installed properly in the first time, it always will not work after I restart the computer (it becomes Unknown Device inside Device Manager's Device List), I always have to unplug and replug the device again for it to work properly. The second problem: if I use MS devcon or Walter Oney's FastInst to install the .inf file automatically, I will always have BSOD right away. However, if I install manually by running the Windows Install Driver Wizard and select the .inf file, it can be installed without any problem. So my question is: is there a common mistake (e.g. forget to handling certain IRPs) that could cause the above two problems? I already ask our vendor and they seem quite clueless, so I would like to ask if anyone here have experienced it before and could shed some lights for me to speed up our vendor.

    - Ethernet bridge on WXP and IM driver I have one problem with my ndis IM driver running on WinXP with network bridge. First - on W2K3 bridge all i OK, I am seeing that IM driver is bound to "MAC bridge miniport" but also on both ethernet interfaces which is bridge composed of. But on WXP there is a bit amazing result: I am seeing that installed IM driver is bound only to "Mac bridge miniport" and I am not seeing bindings to both ethernet adapters which is bridge composed of. Second relating to this is that on WXP with bridge in my IM driver there does not go packets in outgoing direction. All packets going through IM driver on WXP with created bridge are incoming. I am seeing that this is true for packets entering through one bridged interface and leaving through second but also vice versa, so all pakcets in both directions in IM driver I am seeing like incoming packets through my PtReceiveHandler. question: Is possible also on WXP to set something and to have IM driver bound to both ethernet interfaces in bridge like on W2K3, and not only to MAC bridge miniport ?

    - How do I get a devices "Device Instance ID" programmatically Hi all, I've been working with the SetupAPI (SetupDiXxx) library in C#. It's been a challenge due to my lack of C++/WinAPI skills/experience, but I've made some great progress. I'm having problems getting a device's instance ID. Like the ID seen in the Device Manager (in case this term is ambiguous). eg. USB\VID_03F3&PID_0093\024290079102 Thus far, -- I'm able to get the ClassGuid as defined in http://msdn.microsoft.com/library/default.asp?url=/library/en-us/devinst_d/hh/DevInst_d/setup-cls_f7544122-69a3-4b34-85f5-db3714408026.xml.asp by calling the SetupDiClassGuidsFromName(...) function. -- I'm able to to create a Device Information Set (HDEVINFO) using this ClassGuid by calling SetupDiGetClassDevA(....) -- I then loop through the elements in this Device Information Set by calling SetupDiEnumDeviceInfo (...) where I'm also fortunate enough to have my SP_DEVINFO_DATA struct populated. This is where I'm having troubles. I'm not sure whether I'm calling the correct function to retreive the Device Instance ID. I was lead to believe that I could use SetupDiGetDeviceInstanceID(...) function and attain the Device Instance ID via its out parameter "OUT PTSTR DeviceInstanceId", but I'm just getting strange text at best. I don't know whether I'm barking up the wrong tree by calling this specific function or rather I'm PInvoking incorrectly this specific function. I've tried numerous variations within my PInvoke/DllImport and have struck out so far each time, some worse than others. Any advice or clarification would be greatly appreciated.

    - local buffer size I am developing a dll library used by XP embedded, XP and Windows 2000 applications. How big of a local buffer is ok? None of these functions are recursive but some of my functions will internally call some other function meaning stack required in the system can be two or three times more than required for one function. I am thinking of stack problems if I define a big local buffer (buffer of 50K ) in functions. I am sure I wont need more than 50 K for the function because of other constraints. Should I allocate memory dynamically and free it before leaving the function. My arguement is defining local buffer is kind of dynamic memory because stack is released after the function call. Is it a good practice to define big buffers on stack. At what buffer size should I stop allocating local buffer and allocate a dynamic buffer. Thanks, Raj Tag: Fonts used in EMF Spool file Tag: 83107

In particular if the service is an autostart one (SERVICE_AUTO_START).

From DDK docs, As I know, at driverentry point, Calling KsInitializeDriver function will initialize the the driver object of an AVStream minidriver. Then AVStream will call AVStrMiniDeviceAdd(AddDevice routine). At this point, WDM device object is created and KSDEVICE structure is initialed. There is a sensence showed in DDK Doc: Minidrivers can use this routine to associate context information with the AVStream device object, or to initialize a device extension. Question 1: What is context information? Does this mean device extension? If it does, what does device extension belong to? Minidriver? or User-created device extension? Question 2: Can I store User-created device extension in context information? or store into KSDEVICE.FunctionalDeviceObject.DeviceExtension? I try to look up the KSDevice structure. I am confused something,too. Question 3: Does FunctionalDeviceObject of KSDevice belong to this minidriver? If I want to add USB support into BDA, Should I aquire FunctionalDeviceObject for USB? or leave it alone, put USB support in the PDO? or there is another method? Really need experts' help for my confusing. Thanks Roache Tag: Fonts used in EMF Spool file Tag: 83081

    - How to know the BandWidth of a USB 2.0 device? Hi all, I connected my webcam to USB 2.0 port, when live preview, I checked the device manager, it says the USB bandwidth used is 398%! when connect to USB1.1 port, the value is 60%, I think 60% is reasonable. How do I know the actual used BandWidth when connect my webcam to USB2.0 port? Thanks in advance, Barry Tag: Fonts used in EMF Spool file Tag: 83078

    - Bimap character size Hi, I am working on Text rendering in printer driver. I have to download the given text as bitmap, so after downloading the font header information, i am trying to download the character header information, the character header contains 'Left offset', 'Top offset', 'Bitmap width' and 'Bitmap height'. I have obtained the width and height from sizlBitmap member of GLYPHBITS structure, but these vealues are not matching with the required result, like For character 'b' of Arial-12, the Required width=45 i am getting 896 and Requred height=73 i m getting 96 And i am not getting how to find out the left and top offsets. Can anybody help me in obtainig correct values for all these parameters. Thanks. Tag: Fonts used in EMF Spool file Tag: 83076

    - Virtual COM Driver Occurs Surprise Removal Event When CPU Loading is High Dear all, I write a Virtual COM Driver, it can transfers data from COM port to USB port. It's lower driver is USB driver (USBHID.sys) developed by Microsoft. But when CPU Load increase to 100%, a "Surprise Removal" event happens. Though it is not removed from Device Manager, it doesn't work normally. Anyone knows the reason? Any help will be appreciate! Best Regards, David Tag: Fonts used in EMF Spool file Tag: 83072

    - Tutorial for understanding / using the Setup API available for non-C++ wizards? Hi all, Does anybody know if there is a tutorial or documentation that explains the usage of the Setup API for those w/o much unmanaged code experience. I've been working on test automation where we check whether a device can be disabled and then re-enabled. This is a manual test currently which we're striving to move to our automation. I thought that I had this figured out but each perceived step forward in the right direction presents yet another logic error. Currently, we're trying to implement this in C# using PInvoke. I don't have a world of experience/skill w/ C++ nor using PInvoke so this has been quite a challenge. I've been looking at the devcon example included in the Windows 2003 SP1 DDK along w/ various usage examples/soure code online but am still tripping in various places :(. Any guidance/direction would be greatly appreciated! Thanks a trillion, MH Tag: Fonts used in EMF Spool file Tag: 83066

    - Query on USB bus driver Hi all, Currently iam working in faking a usb bus driver. I am catching all the query asked from the class driver which is on the top layer of my bus driver. The problem what i am facing now is in setting the configuration for the class driver? The class driver inorder to set a configuration creating a URB by passing the corresponding configuration descriptor to the bus driver which it wants to set. In response to this query my bus driver has to send a configration handle back to the class driver. How a bus driver will get a handle to a configration? What is the need of this configration handle? Similarly for the interface and endpoints? Please help me Tag: Fonts used in EMF Spool file Tag: 83056

    - question for the pro's I install my NDIS IM driver on a laptop that has an intel wireless adapter and pretty soon it starts blue screening. When I check the crash dump there is nothing in it about my driver ... the crash is happening inside the NIC driver (s24trans.sys) How on earth do I debug this? Even though it is not my driver that crashes, my driver must be partially responsible, because the other driver only begins to crash when mine is installed. I've thought about the idea of installing a checked build of xp on the crashing system and then hopefully the crash dumps might contain more information ... but ultimately I'll still be staring at a bunch of assembler written by MS or Intel! Any ideas? Tag: Fonts used in EMF Spool file Tag: 83055

    - ACPI intercepting power button (and lid switch) questions (XP) Hi, I want to intercept ACPI power button (and perhaps also the lid switch on a notebook) in order to gain more control on what to do depending on application status. Unfortunately the WM_QUERYENDSESSION method is not sufficient to me because a couple of applications (e.g visual studio) terminate themselves even if my app returns that it does not want windows to shutdown/whatever. How is the button press communicated from kernel to user space? (same for lid switch) What windows process is the first consumer of these events? Which windows process is displaying the dialog for standby, power down, restart if the power button is configured for "Ask what to do" ? (winlogon, crss, ... ) While poking around I installed a custom gina dll (using the original msgina.dll but created a GinaDLL registry entry). As soon as this GinaDLL entry was present, the system displayed the old fashioned dialog instead of the new colorful XP shutdown dialog. With help of a small program I discovered that the dialog window which has focus (after a power button press) seems to belong to the windows explorer process . Interestingly when I kill the explorer the same dialog is being displayed nevertheless, so there seems to be more than one process which can display the power down dialog. Please help me to understand better whats exactly going on after power button press. Regards, Konrad Tag: Fonts used in EMF Spool file Tag: 83029

How can I find out which fonts are used in an EMF .spl file?

I found out that one way to do it is by enumerating all records in the
metafile, looking for SelectObject records and if a font, examining its
entry in the handle table.

Is there another way to do it?

Thanks
