    - Page limit when using GDI to print Although this is a client side issue, I believe the real issue is a buffering limit in the printer driver. Since our Unidrv-based printer driver is the first driver Iâ??ve ever worked on, I am curious if I am diagnosing this problem correctly and if I understand all possible solutions. We are experiencing a page limit when using GDI printing. After printing 85 pages from our application, we get a failure. We raised our Unidrv-based printer memory limit to 2 GByte maximum and printing fails consistently on the 86th page. This happens whether we print to an external printer or to our Unidrv-based software PDF printer, i.e. a printer that creates a PDF document. When we print from our application using GDI printing, the return value for the EndPage function for the 86th page is 0cFFFFFFFF, i.e. -1, and GetLastError returns 0 (zero). We then call AbortDoc. If I modify the code to allow printing to continue, only the first 85 pages are printed. The same thing happens on an external printer. Note, we do not believe that any pages approach the 350 MByte limitation mentioned in the documentation. Also, if we delete pages at the beginning of the document, then the document will still print only 85 pages, i.e. some pages that previously didnâ??t print suddenly print. Is the only solution to reduce the color-depth the 24 bit color images ouor application produces, and of course, greatly reduce the size of the images for gray scale or black and white printing? Then Ican modify the device context to reduce the memory requirements for each page. Is there anything else I can do? If that is the solution, do printers typically use 16 bit color, 8 bit color, or something else? We do need to be able to print photographs to high quality printers, but the buik what our application deals with is black and white documents. If those documents contain a color photograph we do want to support printing that without such a small page limit. We've heard of customer documents that exceeded 4000 pages! (Granted, these are quite rare, but 1000 pages is no unheard of). Thanks in advance. P.S. Our printer driver is a Unidrv-based PDF printer driver, i.e. it produces PDF files. It was built using DDK 3790. We support Windows 2000 and Windows XP. It was developed using the Unidrv sample code provided in the DDK. The printer-generated PDF file is sent to an application we also have developed, i.e. there is no hardware printer. ------------------------------------------------------------------------- I posted the message above in the win32.programmer.gdi newsgroup in a post titled "Page limit when using GDI printing.", and I received the reply below from Rhett Gong [MSFT]: Note however, despite his reply, that this is NOT just a Unidrv issue. It happens when using GDI to print to other printers. I responded in that forum, and included the calculation that shows that 2 GBytes will handle 85 8.5 inch by 11 inch 300 DPI 24 bit color images. (2 to the power 31) / ( (300 DPI * 8.5 I) * ( 300 DPI * 11.0 I) * 24 bits/pixel) ) = 85.0 This is what makes me believe the page limit is related to buffering in the driver (or at least buffering somewhere). The issue is that printing doesn't start until EndDoc() is called. Is it reasonable to raise the driver buffering way above the virtual memory limit? Is this data all mapped to a file? I do not want to segement a 1000 page print job into multiple jobs as these arrive back asynchronously from the Unidrv printer and are loaded into our application. Having to append these over and over again would annoy most users. Note also, there are two separate issues. 1. GDI to other printers. 2. GDI to our Unidrv-based printer. A solution to either of these would be useful. Is this a fundamental limitation of GDI printing? (An answer to that would help me to stop pursuing something with no solution). ------------------------------------------------------------------------- Hello From your description, you write a Unidrv by yourself, but you can only print 86 pages and then EndPage return -1 and not further error code returned . Based on my understanding, this is a Printer Driver issue and require debugging into the printer driver to find out the problem, so I would suggest you post this question to following newsgroup: microsoft.public.development.device.drivers It is a managed newsgroup. and all DDK issues and driver dev questions are posted in the newsgroup above. The reason why we recommend posting appropriately is you will get the most qualified pool of respondents, and other partners who the newsgroups regularly can either share their knowledge or learn from your interaction with us. Also, this is to make sure that the responders can better track the problem.

    - Synchronizing Timers and ISR I am attempting to synchronize Timer procedures with the ISR. When my timer expires it should perform operation A. If the ISR runs prior to that it will perform operation B and cancel the timer. What I am concerned about is the possiblity that the timer will expire, start executing, and get interrupted prior to reaching the Critical Section. In this scenario, Operation B will be performed by the ISR followed by Operation A by the timer. Is there a method to prevent this from happening? Thank you. Tag: multicast ping Tag: 72229

    - Correct DDK Windows 2000 SP4 I have Visual Studio 6, my O.S. is Windows 2000 SP4. According to the MSDN order site the correct DDK for my system is the Windows Server 2003 SP1 DDK, which I ordered. My main interest in the DDK was to obtain the Usbview,c source code, however Usbview.c will not compile on my system, it generates errors. I have been told by a systems developer that I need the 'Windows 2000 DDK' in order to compile Usbview.c on my system. The 'Windows 2000 DDK' is now only available to MSDN subscribers and I am not yet an MSDN subscriber. If the above infromation is correct, can anyone here on the forum who has the Windows 2000 DDK post back with the year(s) and month(s) of the MSDN subscription CD that included the DDK. Thank you for your help. Tag: multicast ping Tag: 72217

    - Migrating from KS1.0 (stream.sys) to AVStream Hi, When I have the sources of a driver that currently uses KS1.0 (stream.sys) is it difficult to rewrite the driver so that it uses AVStream instead? What would be a good starting point of rewriting the driver? Does it also effect the application that I'm currently using or do I need to rewrite the application as well? Avi Cohen Stuart.

    - Problems performing USB Isochronous/Bulk Read/Writes and unplugging device Hello all, hello Mr. Roberts! After clearing some general misunderstandings, maybe you could help me once more with the second part of my former post. I would be very grateful for your assistance. I described it as follows: >Depending on the pipe type I leave the dispatch routine forwarding the >current Irp and device object to a validation routine for isochronous >transfers (because they are more complicated) or bulk transfer >completion routine. Isochronous completion is done as it can be seen >the original sample. Microsoft did in their samples the validation for >isochronous and both validation and transaction in the case of bulk >transfers in the dispatch routine. Although I copied and pasted the >whole algorithm from their (fine-working [standalone]) drivers, the system >crashes when I try to perform a bulk/isochronous read or write. What >rule did I violate? Moreover I recognized the same crash behaviour when I unplug one or both devices. I tried to get some debugging messages via DbgView from Sysinternals, but the system crashes, without storing the information into the given log file. I checked the in- and decrements on the stack without result. They seem okay to me. Since I solely introduced the validation routine for isochronous transfer and sourced the transfer algorithm of the bulk transmission out, I assume it must have something to do with the parameters I forward to these functions. I appreciate your help in advance, special thanks to Mr. Roberts who helped me this far. Tag: multicast ping Tag: 72211

    - NDIS driver sample code for SDIO interface Hi, I am developing a SDIO driver for our chipset. The output from our chipset is IP datagram carry realtime video. I need to give the IP datagram to the NDIS protocol stack then pass to Windows CE media player does anybody have any NDIS example for WinCE I can follow? I understand how to transfer data via SDIO interface the experience I am lacking is after I get the data how do I pass to upper layer protocol stack (NDIS) so when user want to watch live TV using windows media player they can do it. It should be similar to 802.11 just the out put from our chipset is IP packets not Ethernet packet Tag: multicast ping Tag: 72209

    - SMART_GET_VERSION returns ERROR_INVALID_FUNCTION On Windows XP the SMART_GET_VERSION code for PhysicalDrive0 (a SATA drive) works. On Windows 2003 Server SP1, the same code fails with ERROR_INVALID_FUNCTION. I've searched the DDK and knowledgebase without any luck of finding the necessary information. Why does the code fail? I've found a workaround using SCSI_MINIPORT and \\.\scsi0 device name. Please see below. sprintf(devcName, "\\\\.\\PhysicalDrive%u", deviceId); devcHndl = CreateFile (devcName, GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL); if (devcHndl == INVALID_HANDLE_VALUE) { printf("cannot open device %s error %d\n", devcName, GetLastError()); } retVal = DeviceIoControl(devcHndl, SMART_GET_VERSION, NULL, 0, &versionInfo, sizeof(GETVERSIONINPARAMS), &retSize, 0); if (retVal) printf ( "Device........... %s\n" "Driver version... %1d\n" "Revision......... %1d\n" "Device map....... 0x%02x\n" "Capabilities......0x%02x\n", devcName, versionInfo.bVersion, versionInfo.bRevision, versionInfo.bIDEDeviceMap, versionInfo.fCapabilities); else printf("DeviceIoControl (SMART_GET_VERSION) for %s error %d\n", devcName, GetLastError ()); CloseHandle(devcHndl); Workaround: sprintf(devcName, "\\\\.\\scsi%u:", controllerId); devcHndl = CreateFileA (devcName, GENERIC_READ|GENERIC_WRITE, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL ); if (devcHndl == INVALID_HANDLE_VALUE) { printf("cannot open device %s error %d\n", devcName, GetLastError()); } PSENDCMDINPARAMS cmdIn = (PSENDCMDINPARAMS )&iobuff.cmdBuff; memset(&iobuff, 0, sizeof(iobuff)); cmdIn->cBufferSize = 0; cmdIn->bBuffer[0] = 0; cmdIn->bDriveNumber = (BYTE) deviceId; //For IDE: 0=master; 1=slave; actual ID for SCSI iobuff.srbCtrl.ControlCode = IOCTL_SCSI_MINIPORT_SMART_VERSION; iobuff.srbCtrl.Length = sizeof(iobuff.cmdBuff); iobuff.srbCtrl.HeaderLength = sizeof(SRB_IO_CONTROL); iobuff.srbCtrl.Timeout = 1000; memcpy(iobuff.srbCtrl.Signature, "SCSIDISK", sizeof(iobuff.srbCtrl.Signature)); retVal = DeviceIoControl(devcHndl, IOCTL_SCSI_MINIPORT, &iobuff, sizeof(iobuff), &iobuff, sizeof(iobuff), &retSize, 0); if (retVal) { versionInfo = (GETVERSIONINPARAMS *) iobuff.cmdBuff; printf ( "Controller........... %s\n" "Device........... %1d\n" "Driver version... %1d\n" "Revision......... %1d\n" "Device map....... 0x%02x\n" "Capabilities......0x%02x\n", devcName, deviceId, versionInfo->bVersion, versionInfo->bRevision, versionInfo->bIDEDeviceMap, versionInfo->fCapabilities); } else printf("DeviceIoControl (IOCTL_SCSI_MINIPORT) for %d error %d\n", controllerId, GetLastError ()); Thank you in advance.

    - Should UsbIntel driver go to D3 or D0 inIdleNotificationRequestComplete We are making USB image capture device with a driver like UsbIntel. I added IdleNotification routine to the driver. A PC pluged in our device wasn't able to suspend sometimes. My attention is in PoRequestPowerIrp call of IdleNotificationRequestComplete. Now our driver code is as below. powerState.DeviceState = PowerDeviceD0; PoRequestPowerIrp( ... IRP_MN_SET_POWER, powerState, ... ); When I delete this function call PoRequestPowerIrp, A PC pluged in our device was able to suspend always. But My device power is still off.

    - Bulk and Iso-Transfers in one USB-Driver Hi all, I'm searching a reliable way to detect the pipe type of an IRP. I tried to read this information like Microsoft did in their Bulk Driver Sample from the DDK. In the dispatch routine I check for upcoming idle requests. Then I get the current Irp, the current file object, the pipe information and that's where I get the current pipe type from. I understood that every IRP stores information about what transfer type is at hand. Is that right? Depending on the pipe type I leave the dispatch routine forwarding the current Irp and device object to a validation routine for isochronous transfers (because they are more complicated) or bulk transfer completion routine. Isochronous completion is done as it can be seen the original sample. Microsoft did in their samples the validation for isochronous and both validation and transaction in the case of bulk transfers in the dispatch routine. Although I copied and pasted the whole algorithm from their (fine-working single) drivers, the system crashes when I try to perform a bulk/isochronous read or write. What rule did I violate? I'm through with W. Oneys book and the USB specification and the firmware and the application. Although this work is part of my internship and I'm (quite) new to this field I'm seriously trying to get the best out of my work. I appreciate your ideas very, very much!

    - Possible to write data to SMBIOS from ACPI operation region?? I have been reading the docs on ACPI operation regions and it seems that these regions are only useful for getting data from the BIOS, is this true? I have a need to access an SMBIOS interface which requires punching a physical address into a CPU register directly and then writing an I/O port. I was wondering if this interface could be converted to an ACPI op region and avoid all of the non-standard, non-WHQL approved kernel calls that are necessary to make this work? I notice that their are two access types listed for these regions "cooked" and "raw". The latest docs say "raw" access isn't implemented yet. I am guessing this is what would be needed for this type of interface yes? Originally, I was hoping that ACPI op region buffers were shared between BIOS and ACPI op region registrars, but it appears that the data flow is only one way, yes? Any pointers on how these op regions work and even better how an SMBIOS interface such as this could be accessed in a cleaner fashion would be much appreciated. BTW, for the sake of discussion assume I can modify the BIOS at will. Bill M. Tag: multicast ping Tag: 72140

    - Hibernation problem for USB device without ROM firmware We make use of a USB device that gets its identity changed dynamically after the firmware is downloaded by our driver. The device has a unique VID and PID that is used for the two sets of drivers. The first VID & PID are burned into the ROM and it is not the USB chip manufacturer's VID/PID. I have searched through the archives and found a similar issue discussed along with a workaround suggested by Microsoft. (Attached below) Our device is not quite as schizophrenic since it has our own VID/PID before the downloading of firmware. Anyway, I preferred to test the second design for hibernation so I created a compound device with a hub. I installed a lower filter driver to our hub and tried to download the firmware during power up, but I found that the request (IOCTL_INTERNAL_USB_SUBMIT_URB with URB_FUNCTION_VENDOR_DEVICE) fails with STATUS_DEVICE_POWERED_OFF when I download the firmware before calling PoCallDriver (this is an experiment and what I expected). Also I get STATUS_DEVICE_NOT_CONNECTED when I download the firmware after PoCallDriver and this is not what I expected. It seems to me from my experimentation that this is not a realizable solution. I realize this suggestion was made "AS IS", but I was wondering if the concepts have ever been tested or what I might be missing? --- the following is the workaround --- Newsgroups: microsoft.public.development.device.drivers From: "Eliyas Yakub" <eliy...@microsoft.com> - Find messages by this author Date: Wed, 22 May 2002 12:16:04 -0700 Local: Wed, May 22 2002 3:16 pm Subject: Issues with schizophrenic devices (fyi) Reply to Author | Forward | Print | Individual Message | Show original | Report Abuse I brought to our PNP developer's attention nasty driver design issues people are running into with reprogrammable PCI (FPGA/DSP) and USB devices. We saw couple of those in recent days (Triggering a PCI bus re-scan) in this forum. Here is his response: ********************** Our customer needs to be warned that this type of hardware may not be productizable. The design (a reprogammable PCI FPGA chip that disappears and reappears as another device) is similar to some of the USB programmable DSP designs we've also seen problems with. Both of these designs run into major problems with PnP and Power Management. Problems -------- Identification - In its default state, the device usually exposes generic "DSP/FGPA" IDs. An INF targets those IDs and specifies a driver that'll transform the hardware into something else. If two different hardware vendors each use the same reprogrammable chip, their INFs will both match against the same DSP/FGPA IDs. The OS doesn't know which driver to pick. Even better, insert a card from each vendor - mayhem ensues as one of the cards will get the wrong payload. Power Management - During power management operations (hibernation, suspend, etc), all power is often removed from the chip. When this happens, the chip typically loses its new identity and reverts back to its DSP/FPGA form. To the OS, this appears to be a surprise removal (the card disappeared). All the handles opened by applications against the device will go dead. The application might reestablish contact when the original device appears to be "reinserted", ie the load sequence has repeated, but there is no gaurantee of this. Plug and Play - Some Plug and Play operations may result in power loss (rebalance), leading to the problem above. Updating the driver also temporarily places the hardware in D3. Depending on the bus, this may result in a state loss, causing the device to "disappear" just as the OS is planning to reload the new drivers. A reboot popup may result from this. How To Make FGPA/Reprogrammable-DSP Designs Work ------------------------------------------------ The best designs simulate a bridge/hub with devices behind it. For instance, the following design of a PCI FGPA works properly with Windows: 1. The PCI FGPA simulates a PCI-to-PCI bridge. 2. The PCI FGPA logic retrieves the IDs for the bridge from an EEPROM, ensuring no possible overlap with other customers using the same chip (the IHV is expected to contact the PCI SIG and retrieve such IDs.) 3. The INF for the FGPA specifies PCI.SYS as the FDO (using NEEDS and INCLUDE directives to reference machine.inf as needed), and specifies a lower filter driver that will deliver the payload. 4. During IRP_MN_START_DEVICE, the filter driver downloads the payload to the FPGA. The FPGA now appears as a bridge (same IDs) with a *child* behind it. The child represents the IHV's device. 5. After start, the OS enumerates the bridge. Since the child is present, the OS loads the next set of drivers. 6. During powerup from suspend or hibernation, the OS first powers up the bridge. The filter driver takes this opportunity to reapply the payload if necessary. Here is a similar design for a reprogrammable USB chip: 1. The USB chip simulates a hub. 2. The USB chip retrieves the Vid/Pid IDs for the hub from an EEPROM 3. The INF specifies USBHUB.SYS using NEEDS and INCLUDE directives targeting USB.INF. The INF also specifies a special lower filter driver to download the payload. 4. During IRP_MN_START_DEVICE, the filter programs the USB chip to appear as a hub with a device behind it. 5. After start, the OS enumerates the hub and discovers the child. 6. During powerup, the OS always powers up the hub before the child. The filter reapplies the payload during hub powerup. And another USB design: 1. The USB chip simulates a *composite* USB device. 2. The USB chip retrieves the Vid/Pid IDs for the hub from an EEPROM 3. The INF specifies USBGCCP.SYS via NEEDS and INCLUDE directives (similar to above). 4. During IRP_MN_START_DEVICE, USBGCCP will read descriptors from the hardware to determine which functions are exposed by the composite device. The driver (a lower filter) would reprogram the hardware to specify child during Start, before the IRP reached USBGCCP. 5. During powerup, the driver would reapply the payload as needed. -- -Eliyas This posting is provided "AS IS" with no warranties, and confers no rights. Tag: multicast ping Tag: 72127

    - printer port monitor question re: drag-n-drop install I've got a question about port monitors and drag-n-drop printer installation. When you drag a printer from a server to a workstation, what happens to the port monitor that the printer driver(on the server) is using? Fron the printers folder, clicking on the printer's Properties/Ports tab shows the printer on the workstation is using the same port as the printer on the server is using. However, if you do File/Server Properties from the printers folder and look at the ports tab, the port is nowhere to be seen. If it's a non-standard port monitor (ie, not included with windows), the port TYPE isn't even there. (and you can't configure the port) So what port is the workstation printer actually using? Is this documented anywhere? I am especially interested in any information regarding user-written port monitors in this situation. Thanks, ScottR -- Scott Robins Tag: multicast ping Tag: 72120

    - USB (Camera) Device Driver. We are working on USB device driver for camera. We are facing problem in accessing data through video pipe (or Interrupt pipe) using bulk transfer. URB is built using UsbBuildInterruptOrBulkTransferRequest. All the three flags InvokeOnSuccess, InvokeOnError and InvokeOnCancel are enabled while setting callback function using IoSetCompletionRoutine. But USBD is calling the callback function only on InvokeOnCancel. In other cases were URBs are built using UsbBuildGetDescriptorRequest, USBD_CreateConfigurationRequestEx or UsbBuildSelectConfigurationRequest, the callback function is called on InvokeOnSuccess. Following observations are made. 1) The return value (NTSTATUS) of IoCallDriver is STATUS_LICENSE_QUOTA_EXCEEDED (not error), indicating status pending. This return value is observed in some other cases also but after sometime the callback function is called on InvokeOnSuccess. But in case of URB created using UsbBuildInterruptOrBulkTransferRequest, the callback is not called unless IRP is canceled (InvokeOnCancel). 2) Buffer is filled with some standard data before calling IoCallDriver and observed that the data is not changed, indicating that no data is obtained. This observation is made when the callback function is called on InvokeOnCancel. Since only while building URB using UsbBuildInterruptOrBulkTransferRequest we are using pipe details, we concentrated on the pipe details and concluded the following, 1) Pipe handle is valid. 2) Buffer is valid and is of proper size. 3) Current transfer size is proper. 4) Transfer flag is also proper. Is there anything we are missing to check? I am confused in concluding where am I going wrong. Is there anyone, facing the same problem? Any help will be grateful. Thanking in advance.

    - Win 2K Unidriver CmdXMoveAbsolute,CmdYMoveRelDown problem. Hi there! I have been wrriting a Print Driver. this is work fine on Windows 9x. therefore i convert win 9x .rc to win 2k .rc that was used Win 2k Mini driver tool. and some fonts file .pfm to .ufm, too. I had inserted some fonts that is barcode and text. Both text work fine. but barcodes are incorrect that is printed a text. i print a data to file:(port) and i check that binary code. i found some problem. belowe is correct: 1. send font command(<1Bxx~>) 2. printing data("123456789012") ;output => <1Bxx~3132333435....> ; win 9x print data but real output data is incorrect. below incorrect: 1. send font command(<1Bxx~>) 2. CmdXMoveAbsolute(<1Bzz~>) 3. CmdYMoveRelDown(<1Byy~>) 4. Printing data("123456789012") ;output => <1Bxx~1Bzz~1Byy~3132333435....> i have text data "123456789012". i didn't want this text data. i'd like to get barcode data. how to get same output data like windows 9x. how to solve this problem ?

    - Not seeing "cancelled" status when I cancel my URB I have a (high-speed) USB driver which generates multiple isochronous urb's and queues them up, one after the other, through IoCallDriver() with a Completion routine set and all three flags (Success/Error/Cancel) set True. On certain conditions I need to cancel all these URB's; I happen to have kept a list of the requests so I can either call IoCancelIrp() on each or just do a URB_FUNCTION_ABORT_PIPE on the pipe. In either case, I don't see a STATUS_CANCELLED on the Irp when the completion routine is called on the outstanding transfers [I do see STATUS_DEVICE_NOT_CONNECTED if I yank the cable]. These transfers are entirely internally-generated - there's no upper layer Irp's involved in this. Now its possible that the 'cancelled' Irp/Urb's have in fact completed successfully by the time I do the cancel, and that this is why I get zero status - I'm not sure how to prove/disprove that idea right now. But I wondered if there was anything else I might have overlooked/misinterpreted? Thanks. Tag: multicast ping Tag: 72081

    - Hooking api In a previous thread I was directed by some gentlemen here how to hook an api function. Specifically I need to hook the callback waveInProc which is called by the system in a multimedia event. Here is the waveInOpen function prototype: MMRESULT waveInOpen( LPHWAVEIN phwi, UINT_PTR uDeviceID, LPWAVEFORMATEX pwfx, DWORD_PTR dwCallback, DWORD_PTR dwCallbackInstance, DWORD fdwOpen ); and here is the waveInProc function (which the user should define and implement):void CALLBACK waveInProc( HWAVEIN hwi, UINT uMsg, DWORD dwInstance, DWORD dwParam1, DWORD dwParam2 );Inside my waveInOpen function I modify the callabck paramter from dwCallback to MywaveInProc.Inside my MywaveInProc, I should call the original waveInProc(dwCallback) function(which I know only its address). I never called an address with paramters and I don't know how to do it.My question:Can someone refer to specific code explaing/demonstrating how to do it? Thanks in advanceI.

My network driver supports multicast. I have tested with multicast
applications and it works fine. But when I issue ping 224.0.0.1 from command
prompt, it doesnt reply to that though it has joined the group already
through ndis oids. I have tried setting IGMPLevel to 2 in registry. Will this
work at all? I am testing on Windows2003 server. Should I tune in additional
parameters?

thanks

There should be some utility in the Resource kit for diagnosing IGMP,
check it. NDIS OIDs (alone) is not a way to join a multicast group.
