 - Resources assignment Hi!, I have a couple of questions: The device for which I'm writting a wdm driver has I/O ports, memory ranges, DMA and IRQs. So I've been writing a basic driver (just to read a port). 1. My first doubt is: If I only write in my start device routine that I have I/O port resources, could be a problem? I mean by just ignoring the other resorces, could a problem arise? 2. When the PnP manager sends me a filter resource requirements irp, does that mean that there is no information about the resources "inside" my device? Or is because of my driver?? Thanx Tag: Communicate with printer driver. Tag: 37294

 - USB SCard Reader Driver Hello ! I need to write a USB SCard Reader driver. DDK provides an example of USB generic device and an example of PCMCIA SCard Reader. Is it possible to somehow merge them ? Or may be there is another way to build a USB SCard Reader driver without developing it from the scratch ?

 - Createfile failed(access denied) when logged on as limited user I have written a NDIS IM device driver and I used IOCTRL to communicate between my user mode app and the device driver. It works fine when logged on as Administrator but createfile fails (access denied) when logged on as limited user. Anyone know how to get around this? I called create file with the following attributes. CreateFile (TEXT"\\\\.\\MyDriver"), GENERIC_WRITE | GENERIC_READ, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL |FILE_FLAG_OVERLAPPED, 0); Is this to do with how I installed the driver or the way I called createfile?

 - 802.1x - Setting the Dynamic WEP Keys Hi, I am writing an application that allows a user to connect to 802.1x access points. I connect to the access point, and use EAPOL to get both the broadcast and unicast keys. I try setting the keys using OID_802_11_ADD_WEP, but I don't get a valid connection (i.e a valid DHCP connection). Here is some pseudocode of what I am doing: if (!SetInfrastructureMode(Ndis802_11Infrastructure)) return FALSE; if (!SetAuthenticationMode(Ndis802_11AuthModeOpen)) return FALSE; if (!SetEncryptionStatus(Ndis802_11Encryption1Enabled)) return FALSE; if(!SetSSID(strSSID)) return FALSE; // do EAPOL code, to get WEP Keys if (!SetWEPKey(broadcastkey, keyLength, keyIndex,bBroadCast /*= TRUE */)) return FALSE; if (!SetWEPKey(unicastkey, keyLength, keyIndex,bBroadCast /*= FALSE*/)) return FALSE; The keys get set correctly, but I do not get a valid DHCP address. I found some Microsoft documentation, that basically said that unicast keys are not supported yet. Is this true? It also set that only one key can be set. The last key set is the active one. So I have tried only setting one of the keys, and it still does not work. Also below is a sample of how I set the WEP key. PNDIS_802_11_WEP pWEP; UCHAR * pOidData = NULL; int nLength; nLength = keyLength + 12; // D311 has a problem if the data is not at least 16 bytes long and has a 4 byte boundary if (nLength % 4) nLength += (4 - (nLength % 4)); pOidData = new UCHAR[nLength]; memset(pOidData,0,nLength); pWEP = (PNDIS_802_11_WEP) pOidData; pWEP->Length = nLength; // sizeof NIDS_802_11_WEP structure, this includes length of network key if (bBroadcast) pWEP->KeyIndex = keyIndex | 0x80000000; // we set bit 31 to specify global key else pWEP->KeyIndex = keyIndex; pWEP->KeyLength = keyLength; memcpy(pWEP->KeyMaterial,pKey,keyLength); If someone could tell me what I am missing or what I am doing wrong, it would be greatly appreciated.

 - Sending a WM_ message from WDM to app Hi all! How can I send a windows message to an application from a WDM driver? Several years ago I wrote a VxD driver for an ISA device used in our equipment. Through an IOCTL message, our application would pass its handle and the VxD would store it. When the VxD had something ready for us it would use the handle to send the app a windows message at which time we might have to do some sort of IOCTL to the driver or more commonly read a message in dualported memory. Good or bad programming practice it worked quite well. We are migrating to XPe and I'm trying to translate this possibly dubious practice from VxD to WDM. I have all the tools. XP DDK, Walter Oneys book and Compuware Driverworks. I used VtoolsD for the last driver.

 - how to deal with packet in calling NdisMIndicateReceivePacket I am trying to write a virtual network drive which the incoming traffic is from DeviceIoControl routines instead of a "real" NIC. Whenever the driver get any incoming traffic, it should call NdisMIndicateReceivePacket() to notify the protocol driver that a packet is ready. However, one of the input is (PPNDIS_PACKET) ReceivePackets. It turns out that there should be an array of packets. Here are my questions: 1) How often should I call NdisMIndicateReceivePacket()? 2) How should I deal with the packet array allocation? Should I allocate packet and associated buffer space in initialization? or whenever I need? Thanks!! Tag: Communicate with printer driver. Tag: 37252

 - Virtual Printer Driver Hi, I have to develop a virtual printer driver which can do the following stuff: - generating a bitmap( color/monochrome) - generation a textfile, in which all DrvTextOut string are stored - the complete strings should be parsed and replaced, if needed( special sequences ) - the replaced string should be updated in the bitmap I have tested both the msplotter sample in which I can easily acess the text in DrvTextOut and the oemdll sample in with which I can generate a bitmap. But the parsing and manipulation of matched string in the bitmap makes me headaches. Can a unidriver plugin do all the things? Any hints, tips are welcome.

 - SetupDiGetDeviceRegistryProperty The MSDN online suggests in "Driver Information in the Registry" http://msdn.microsoft.com/library/default.asp? url=/library/en-us/install/hh/install/install-over_6e3r.asp That IoGetDeviceProperty() and SetupDiGetDeviceRegistryProperty() be used instead of accessing the registry directly. I'm interested in getting the resources used by drivers. I realize that Device Manager reports these resources and so they are available. I tried using IoGetDeviceProperty, but blue screens with PNP_DETECTED_FATAL_ERROR 0x02 got in my way, thus I'm looking at SetupDiGetDeviceRegistryProperty(). However, the DevicePropertyBootConfigurationTranslated is not apparently available from SetupDiGetDeviceRegistryProperty (). The SPDRP_DEVICE_POWER_DATA doesn't provide the resources, and I'm looking at SPDRP_DRIVER which provides the Driver Key in the registry (Software Key). It also refers back to "Driver Information in the Registry." Can I get the resources for drivers without looking in the registry? Do I have to read the ...\Control\AllocConfig which is a REG_RESOURCE_LIST? And if so, what is the format of that binary data, a CM_RESOURCE_LIST type of thing?

 - Audio Midi Driver Hello, This is an audio/midi driver related problem. I hope somebody can help. I try to write a simple midi-in driver where data is transfered from a device to some midi software application. Therefore i took the DDK dmusUART sample as a basis and modified it to my needs. Now the driver is just for input. By orienting at the sample and the DDK documentation all pin declarations and property request handlers should be correct. The device shows up correctly in the audio device listings and can be selected as input. But when i try to connect the IMXF is created, initialized and the output connects and immediately disconnects. After that the IMFX is destroyed. This happens about 28 times and no data is transfered. After that the application beliefs it ist connected but the driver shows no singns of life anymore and does not react on any further connection attempts. Can anyone help? Thanks.

 - Printer Driver - Unidriver related This GPD code given below is taken from the ddk sample - hplj5.gpd *PrintableArea: PAIR(9600, 12720) *PrintableOrigin: PAIR(300, 220) *CursorOrigin: PAIR(300, 220) *Command: CmdSelect { *Order: DOC_SETUP.12 *Cmd: "<1B>&l2a8c1E<1B>*p0x0Y<1B>*c0t5760x7656Y" } my questions are: 1. What commands does *PrintableArea, *PrintableOrigin and *CursorOrigin insert into the PCL stream ? What is this used for ? I could not find much documentation about this in the DDK help also. 2. The printable area length according to calculation should have been 12760 (13200 - 220 - 220), but here it is only 12720 , where did the 40 units go? I have seen this difference in other In-box GPD's 3.I had created a GPD for my printer, letter paper size portrait mode values are as follows, *PrintableArea:PAIR(9800, 12800) *PrintableOrigin: PAIR(200, 200) *CursorOrigin: PAIR(200, 200) *Command: CmdSelect { *Order: DOC_SETUP.21 *Cmd: "<1B>&l2a8c1E" } When tested with WHQL tool the rectangle did not have the right side. When I changed the *PrintableArea to *PrintableArea:PAIR(9799, 12800) it started working fine. These measures are in terms of 1/1200 of an inch, how did that 1 unit make the difference ? -Thanks in advance Tag: Communicate with printer driver. Tag: 37236

 - FW: Only dmDuplex member(PS Driver) cannot be updated on reason of PROPSHEETUI_REASON_DESTROY ***FW from microsoft.public.ddk.win2000.printer.video Hi All I am developing a PostScript printer driver by modifying WindowsXP ddk samples "Windows 2000 OEM UI Customization Sample (PS)", and encounterring a problem on updating dmDuplex member of public DEVMODE. It's very weird: 1. On original sample, system standard "Layout" and "Color" sheet is hidden, if I don't hide the 2 sheets(directly return E_NOTIMPL in IOemUI2::HideStandardUI()), then dmDuplex can be updated normally. 2. The problem is not reproduced on updating other public DEVMODE members, such as dmOrientation, dmCopies, dmPaperSize and dmScale. I was not using CPSUI to make my plugin property sheets, so I cannot use DrvUpdateUISetting() to update user settings. Below is the testing code I am using to update public and private DEVMODE under reason of PROPSHEETUI_REASON_DESTROY on hrOEMDocumentPropertySheets(PPROPSHEETUI_INFO pPSUIInfo, ...): ... POEMUIPSPARAM pOEMUIParam; PDEVMODE pTestDevmode; pOEMUIParam = (POEMUIPSPARAM)pPSUIInfo->lParamInit; pTestDevmode = (PDEVMODE) pOEMUIParam->pPublicDM; //check value of pTestDevmode->dmDuplex at here: it is 1. pTestDevmode->dmDuplex = 2; pPSUIInfo->pfnComPropSheet(pPSUIInfo->hComPropSheet, CPSFUNC_SET_RESULT, (LPARAM)NULL, (LPARAM)CPSUI_OK); //check value of pTestDevmode->dmDuplex at here: // it is 1 if Layout and Color sheet is hidden. <-- Problem! // it is 2 if Layout and Color sheet is not hidden. <-- Expected ...

 - Using KeSetTimerEx Hello All, Basically my requirement is to perform some action after every fixed time interval. I therefore create a "synchronization" type timer and using KeSetTimerEx () i schedule the timer. But it looks like the timer is not called at the time interval i need it to invoke the timer callback routine. I check this using KeQuerySystemTime (). Following are the steps: 1) KeInitializeTimerEx (&(pDevExt->myTimer), SynchronizationTimer); KeInitializeDpc (&(pDevExt->myTimerDpc), myTimerRoutine, pKsDev); 2) timerDelay.QuadPart = -180000; // 18 ms KeSetTimerEx (&(pDevExt->myTimer), timerDelay, 18, &(pDevExt->myTimerDpc)); But what i observed to my dismay is that my myTimerRoutine () was called at approximate intervals like: 15.625 ms 15.625 ms 15.625 ms 15.625 ms 31.250 ms and so on as the pattern keeps repeating.... Any reason why this is happenning? Is it possible to make the timer routine be called at the exact timer interval? Also, i used KeSetTimerEx (&(pDevExt->myTimer), timerDelay, &(pDevExt->myTimerDpc)); but the timer routine got invoked only once! Is there something iam missing here? Can someone throw some light on this? Regards, Hari. Tag: Communicate with printer driver. Tag: 37230

 - Help required on Surprise Removal in XP (NDIS5.1) when writing NDIS-WDM Hello, I am writing a NDIS-WDM (USB ) driver for NDIS5.1 (XP). I used the sample from Eliyas. I saw the mailing lists and set the NDIS_ATTRIBUTE_SURPRISE_REMOVAL_OK bit in the call to NdisMSetAttributesEx from MiniportInitialize function. And I implemented the additional MiniportPnPEventNotify function also. When I plug-in the cable, Windows loads my driver. But the "System Tray" icon for "Safely Remove Hardware" appears. When I remove the cable, I get a call to my PnPEventNotify function with SurpriseRemoved event set. There is no pop-up error message as per XP standards. But, I was under the understanding that if the SURPRISE_REMOVAL_OK bit is set, even the "tray icon" does not appear. Please help me in making sure that my understanding is right. If I am wrong, what have I done wrong in the driver that this is not working? Any pointers or any kind of help is greatly appreciated. Thanks in advance for the great help.

 - Did anybody try to write printer drivers for 10 or 12-bit gray level printers? Hi, The majority of printer drivers under Windows support only 8-bit B/W printers or 8-bit per channel color printers. Has anybody every tried to write a printer driver to support 10-bit (or higher) gray level printers under MS Windows environments? Specifically, if I have a 10-bit gray level image and a printer that does support 10-bit printing, I would like the full 10 bits of every pixel go un-truncated all the way from the application to the printing engine. If anybody did this before, could you please share your experiences? How would the 10-bit requirement fits the overall Windows printing architecture? Thanks a lot.

 - IRP FilterResourceReq. and mf.sys not working The problem I am seeing is that my driver successfully requests new PCI memory in the Filter Resource IRP when installed directly but fails when installed through MIcorsofts multifunction mf.sys. I need to allocate an additional PCI Memory Region for a driver to fix a HW config problem. Support Win2000 and later, testing on Win XP. In the IRP_MN_FILTER_RESOURCE_REQUIREMENTS, I allocate memory for a new IO_RESOURCE_REQUIREMENTS_LIST, copy the existing list to the new one, append the new memory region to the end, update count and size, clear and free existing list, link the new one into the IRP, and pass the IRP down. When I install this driver directly for the PCI Vendor/Device ID it works. In the Start Device IRP I see the original resources plus the new resource that I have allocated. After installing, in the Driver Properties Resource Tab, I see the original resources plus the new resource. Driver works fine. The problem comes when I use multifunction mf.sys to enumerate the functions and install the exact same driver in the enumerated function. My .inf installs mf.sys for the PCI Device and Vendor ID and currently enumerates one function. When the driver is installed for that function, I see the Filter Resource IRP but never receive the Start Device IRP. The driver fails to start and indicates it can not find enough free resources and to restart. Restarting does not help still gives same error. Any thoughts or ideas on what could be going wrong? Why does mf.sys effect allocating new resources? I did notice that the resource list is not the same between the two cases. The actual memory and IRQ regions are identical but the standalone driver has some Private Data (Type 0x81) entries as well. Thanks, Stefan L Tag: Communicate with printer driver. Tag: 37167

 - the thread context switch time Hi All, How much time does it take to switch between threads in different processes assuming PASSIIVE_LEVEL and the same priority? Another words is it a very bad/good idea to have the working thread to simplify life? TIA Andrew Tag: Communicate with printer driver. Tag: 37165

 - Can NDIS5 drivers be "chained" in Windows XP? Several years ago we developed an NDIS2 driver in OS/2. When our code is notified a frame is available (typically via ReceiveLookahead indication), it returns SUCCESS to indicate it will accept and copy the frame. If there is more than one driver in the chain, the next driver does NOT get the indication. Our code also returns FORWARD_FRAME when it wishes to pass along a frame to the next driver instance in its chain without accepting it and it returns FRAME_REJECTED when it does not want to accept the frame but also does not want to pass it to the next driver in the chain. The ability to chain together drivers and have those toward the rear of the chain NOT see frames consumed by those toward the front can be an important performance boost in some situations for us. We've recently had an outside company rewrite our driver for NDIS in Windows XP. This driver does not support the idea of a chain of instances where an instance that receives a frame can choose to accept or reject the frame such that any other instances of the driver do not receive the frame at all. The outside vendor cannot determine if/how this can be done in Windows. Is there a way to achieve this behavior in Windows XP? Thanks, Stephen Tag: Communicate with printer driver. Tag: 37164

 - UStatusThread question Hi, we are currently writting a language monitor using the base code given by Microsoft (pjlmon.c). We would like to be able to get a status from the printer every 5 minutes, the printer is bi-di but does not send it's status, except when asked. Is it "legal" or possible to do a WriteCommand in the UStatusThread? We have try it, but it does loop all the time. Have any idea? Thanks Tag: Communicate with printer driver. Tag: 37162

 - [HELP] Virtual Disk Driver - Create symbolic link. Hi there, I wrote a virtual disk driver (use a file to simulate a disk), it works fine. Then I wrote a application runs in RING-3, which can send a customer IOCTL code to the driver, I want the driver create a symbolic link to a driver-letter such as "Z:" when the customer IOCTL code arrival. I did so, modified my source code. When the driver got the IOCTL code, I create a symbolic link between the FDO and \DosDevices\Z:, and the IoCreateSymbolicLink() call return success. But in fact, when I open my explorer, there are no "Z:" driver letter usable. Could you please tell me why? And could you please tell me how to resolve this issue?? Thanks.

 - printable area? This GPD code given below is taken from the ddk sample - hplj5.gpd *PrintableArea: PAIR(9600, 12720) *PrintableOrigin: PAIR(300, 220) *CursorOrigin: PAIR(300, 220) *Command: CmdSelect { *Order: DOC_SETUP.12 *Cmd: "<1B>&l2a8c1E<1B>*p0x0Y<1B>*c0t5760x7656Y" } my questions are: 1. What commands does *PrintableArea, *PrintableOrigin and *CursorOrigin insert into the PCL stream ? 2. The printable area length according to calculation should have been 12760 (13200 - 220 - 220), but here it is only 12720 , where did the 40 units go? 3.I had created a GPD for my printer, letter paper size portrait mode values are as follows, *PrintableArea:PAIR(9800, 12800) *PrintableOrigin: PAIR(200, 200) *CursorOrigin: PAIR(200, 200) *Command: CmdSelect { *Order: DOC_SETUP.21 *Cmd: "<1B>&l2a8c1e-50U" } When tested with WHQL tool the rectangle did not have the right side. When I changed the *PrintableArea to *PrintableArea:PAIR(9799, 12800) it started working fine. These measures are in terms of 1/1200 of an inch, how did that 1 unit make the difference ? Note:I have "-50U" as part of the command to left offset the margin by 50 units i.e. my printers left margin starts at 1/6 of an inch, since the default left margin in PCL is 1/4 of an inch I am adding this left offset command.

 - Accessing PCI Configuration Space I want to know the various other methods of how we can access the PCI Configuration space from our driver. One is the Standrd way of using CM_RESOURCE_LIST structure which is what i am following now, another i know is by accessing the CF8 and CFC register. Please tell me the other Methods for reading the configuration space and retrieving the information from there. Thank You All Tag: Communicate with printer driver. Tag: 37157

 - Cubas SX V1.0 hangs on MIDI initialisation Problem: Cubas SX V1.0 hangs 15 seconds on the MIDI initialisation if our AV Stream driver exports a MIDI Pin for rendering. Detail: The process services.exe uses 100% CPU time during initialisation. The Midi Pin works well with other applications and it works also with Cubase. OS: Windows XP, SP1 DirectX: 8.1 PIN Properties: MajorFormat = KSDATAFORMAT_TYPE_MUSIC; SubFormat = STATIC_KSDATAFORMAT_SUBTYPE_MIDI; Specifier = KSDATAFORMAT_SPECIFIER_NONE; Technology = KSMUSIC_TECHNOLOGY_PORT; The pin does not implement DMUSIC or any other properties. Is it required or recommented to implement additional formats or properties? I'm not sure if this is caused by Cubase, Windows or our driver. Can you give me a hint to solve this?

Hello!

I have a program that prints some documents and I want to add markups to
them. I don't have a source so I can't modify the document :(. Is it
possible to modify the printer driver or maybe try to communicate with it.
Any suggestions how to solve it?

Thanks!
