    - isn't it a sample of virtual port? there is a sample PORTIO in win2000 ddk, isn't it a demo of virtual port? the sample is also included in softice driver suite 3.0. I use win2k DDK to build the PORTIO sample in DDK successfully. But something is wrong when I use the gpdread and gpdwrite to test the driver. I use command line "GpdWrite -b 1 2" to write the number 2 to assigned 'base port address + 1', and then "GpdRead -b 1 "to read out. But the number read out is always 0xFF. I also tested writing a number every 1000 milliseconds and reading every 600 millisecond, but the read-out number kept 0xFF. what does the sample mean? could you tell me why? thanks Tag: CreateFile gives error 5 (Access is denied) Tag: 34492

    - Receiving DBT_DEVNODES_CHANGED from a Windows service I have a Windows service that needs to be notified when a particular device has been enabled or disabled. When either of those actions happen, I have noticed that Windows broadcasts WM_DEVICECHANGE with a wParam of DBT_DEVNODES_CHANGED. Since services don't receive Windows messages, I understand that I should be using RegisterDeviceNotification along with HandlerEx to receive device notifications. However, the documentation for RegisterDeviceNotification says that it only supports the DBT_DEVICEARRIVAL and DBT_DEVICEREMOVECOMPLETE events, which doesn't help me. So my primary question is: How can my service be notified when a device has been disabled or enabled? Related questions: 1. I've heard that some people create a hidden window to receive broadcast messages in cases like this. This sounds kind of weird to me. What are the possible problems with this approach? 2. Also, can what I'm asking about be done from a Windows service with WMI? If so, is there any sample code of WMI being used for this purpose (in a service or otherwise)? Much thanks, -j Tag: CreateFile gives error 5 (Access is denied) Tag: 34490

    - How to use IOCTL_USBPRINT_VENDOR_GET_COMMAND and IOCTL_USBPRINT_VENDOR_SET_COMMAND Hello, I'm trying to use IOCTL_USBPRINT_VENDOR_GET_COMMAND and IOCTL_USBPRINT_VENDOR_SET_COMMAND to communicate with UsbMon(UsbPrint) in my language monitor but I have no idea how to set parametes of device io contorI that will be passed to portmonitor. I need to call GetPrinterDataFromPort of USBMon (portmonitor) inside GetPrinterDataFromPort of Language monitor to get/set some vendor specific data using IOCTL_USBPRINT_VENDOR_GET_COMMAND and IOCTL_USBPRINT_VENDOR_SET_COMMAND command. Are the following codes correct? In case of IOCTL_USBPRINT_VENDOR_GET_COMMAND, cbOutBuffer = 13; //3 1st:Vendor specific code, // 2nd:Vendor Request value - Most Significant Byte // 3rd:Vendor Request value - Lease Significant Byte //+10 size of data to receive lpOutBuffer[0] = VENDOR_SPECIFIC_CODE1; lpOutBuffer[1] = 0; lpOutBuffer[2] = 10; bRet = (*pIniPort->fn.pfnGetPrinterDataFromPort) (pIniPort->hPort, IOCTL_USBPRINT_VENDOR_GET_COMMAND, NULL, NULL, //pInput, 0, //cbInput, lpOutBuffer, cbOutBuffer, lpcbReturned); //...wait until this function finished... // Can I assume that lpOutBuffer[0] is the first byte of data after call above ? In case of IOCTL_USBPRINT_VENDOR_SET_COMMAND, cbOutBuffer = 13; //3 1st:Vendor specific code, // 2nd:Vendor Request value - Most Significant Byte // 3rd:Vendor Request value - Lease Significant Byte //+10 size of data to receive lpOutBuffer[0] = VENDOR_SPECIFIC_CODE2; lpOutBuffer[1] = 0; lpOutBuffer[2] = 10; lpOutBuffer[3] = 0x01; lpOutBuffer[4] = 0x02;....;lpOutBuffer[12] = 0x0A; //Set data here to sent. bRet = (*pIniPort->fn.pfnGetPrinterDataFromPort) (pIniPort->hPort, IOCTL_USBPRINT_VENDOR_SET_COMMAND, NULL, NULL, //pInput, 0, //cbInput, lpOutBuffer, cbOutBuffer, lpcbReturned); //...wait until this function finished...

I have downloaded the DDK. Are there any web sites by MVP's that help? Is there a FAQ? Books? I was told that I have to have a development tool, that Visual Studio 6 will not do this. Is this correct? Help me get started so that I can understand the "vocabulary" of device drivers and better understand the posts in this news group and allow me to ask precise and informed questions.

    - Example class installer for Win98 I've been tasked with writing a class installer for a Win98 driver. Unfortunately, there seems to be a conspiracy of silence on this subject. I have Googled until my mouse cramped. I have searched the Knowledge Base. I have searched the Technical Resources. I have read books (which have said there are no known samples and/or that the task is "hard" and will not be addressed). I simply cannot believe that there is not and never has been documentation on how to write a Windows 98 class installer DLL. After all, such installers do, in fact, exist! I would greatly appreciate any guidance that any of you may have on this topic. Feel free to email me directly, and I solemnly promise not to break the sacred layer of secrecy by telling anyone else of your help. Many thanks in advance. -- Roy M.

    - need help resolving crash cause hi all I have been working on a driver for winXP that emulates a harddisk, based on hardware that connects to the system through some General Purpose IO pins. therefore it is not PnP Enumerable and is "manually" root enumerated using IoReportDetectedDevice(). the DriverEntry and AddDevice routine load fine, and I can use it as the current drive in the CMD utility, read, write and copy from it, until it reports the following correspondence with the system: --------8<------------8<----------- CREATE/CLOSE function issued. major=IRP_MJ_CREATE, minor=0 RemoveLock acquired with tag 80F33330 Unrecognized IOCTL 4D0008h about to release RemoveLock with tag 80F33330 CREATE/CLOSE function issued. major=IRP_MJ_CLOSE, minor=0 CREATE/CLOSE function issued. major=IRP_MJ_CREATE, minor=0 RemoveLock acquired with tag 80F33330 Unrecognized IOCTL 4D0008h about to release RemoveLock with tag 80F33330 CREATE/CLOSE function issued. major=IRP_MJ_CLOSE, minor=0 CREATE/CLOSE function issued. major=IRP_MJ_CREATE, minor=0 RemoveLock acquired with tag 80F33330 Unrecognized IOCTL 4D0008h about to release RemoveLock with tag 80F33330 CREATE/CLOSE function issued. major=IRP_MJ_CLOSE, minor=0 ------------8<-----------8<-------------------- which is followed by the shutdown of all the harddrive- type drivers in the system. my driver is still operable until other services need the original harddrives and start crashing the system. what is the meaning of the above IOCTLs? I can't find this number in any .h file. it must be the result of some sinister #define. I tried to Install the checked version I downloaded from MSDN, but so far the installation either gets stuck in the file copying phaze or stops after not finding the license agreement file (I would appreciate help on this one also). thanks in advance, iddan Tag: CreateFile gives error 5 (Access is denied) Tag: 34457

    - How to install genprint.dll?? Hi~, I'm newbie in ms-windows and VC programming. :) I should develop NT service program that prohibit user's printing any documents. I tested SetPrinter() and I found a problem. Using SetPrinter() can't control network printer that attached in other machine. ('Access denied' error is displayed when calling OpenPrinter() using DesiredAccess set to PRINTER_ALL_ACCESS) So I should find another method. I want to block all printers installed in local machine(local printer and network printer). But for the network shared printer, another computer should can print using this network shared printer. (Only a computer that my program is installed should be influenced by my program) Q.1 Can I hook printing event or job or print spooler? (I think GetJob() also can't filter user's printing job...) I posted this question to many newsgroups or forums but I didn't get suitable answer(may be impossible??...) Now, I'm testing Customized Print Processor using genprint.dll from ddk. I built and copy it to C:\WINNT\system32\spool\drivers\w32x86. And I made its installation program. int main() { ... nResult = GetPrintProcessorDirectory(...,processorPath,...); _tcscat(processorPath, _T("\\genprint.dll")); nResult = AddPrintProcessor( NULL, // server name NULL, // environment name processorPath,//processorPath, // path "My Processor" // ----> what string should I use?? ); } It returns error string("The specified module could not be found."). Q.2 Which string should I use in pPrintProcessorName field? and processorPath string(C:\WINNT\system32\spool\drivers\w32x86\genprint.dll) is right? Q.3 If I success AddPrintProcessor(), how can I change Print Processor to "My Processor" from "WinPrint" of existing printer? Q.4 I can't change Print Processor property of network printer manually(Print Processor button is disabled). That means, using customized print processor also can't control printing network printer?

    - handling multiple interrupts?? hello sir, am working on developing wdm driver for a cpci carrier board.four independent I/O modules can be mounted on a carrier.so in a memory map there are four seperate memory space for each i/o module. usually in a application i call createevent & send it to driver inturn driver calls ObReferenceObjectByHandle - Registers Event in kernal mode. on interrupt driver calls KeSetEvent to notify the app the event. there is a single driver & four different applications comunicating with driver. now the question is how do i handle interrupts?? should each application call create event & send to driver? & how driver notify the different applications correctly when multiple interrupts are generated?? how to hold each application handle & notify to it?

    - USB block size I encountered in my Language Monitor a major difference in data handling when I use a parallel port vs . a USB port to print to my printer. The parallel IO is transferring data in blocks of 64K and the USB has only a block size of 4K. This caused some unexpected behavior at the end of a print job so I am looking for a way to change the block size for the USB port to reflect the same size as the parallel. Does anybody know if I can change the block size when opening the port in the Language Monitor? What about the write and read timeouts, can they be changed down in the Language Monitor as well or is this to be done in an application? Help with these questions is much appreciated. /Manfred Tag: CreateFile gives error 5 (Access is denied) Tag: 34409

    - read Flashdisc on Windows PC (newbie) I have a USB FlashReader from Quatech, PCD-U, which supports a 16Mb PCMCIA PC Card from SanDisk. The cards that I need to read have NOT been written as files on discs, but in what I suppose to be a "regular memory format". The software from Quatech seems to only support "disc formatted" PC cards, although I am by no means sure of that. I am running on a Windows XP machine and am also the proud possessor of a MSDN Universal subscription that seems to include everything from Microsoft that I would ever need. My question is - what do I do next? I cannot seem to find any examples or sample code for reading a flash memory card via USB with whatever handler/driver combo is necessary. Any pointers would be greatly appreciated. TIA Bill Tag: CreateFile gives error 5 (Access is denied) Tag: 34404

    - ksproxy plugin design issues I am considering design choices about controlling custom aspects of a USB2 camera. This camera driver is based on usbcamd2 and is currently proxied by ksproxy. The intent is to create ksproxy plug-ins to result in the following: 1) 1 or more property pages such that amcap, graphedit or the like can set these custom properties and 2) A way to programmatically set these same properties from a dshow filter via some method. Regarding the programmatic control of the filter: a) Is it better to create a custom interface so that from the client filter I can QI the base capture filter or is it better to QI the base capture filter for IKsPropertySet and set the properties directly? The first choice would seem better as it would introduce a layer of indirection such that there would not be such a tight coupling between the minidriver and its usermode clients. b) If I were to use the custom interface, would it be better to implement it via IKsPropertySet or via KsGetObjectHandle and issue IOCTL_KS_PROPERTY? They seem identical. Regarding ksproxy plugins in general. What is the mechinism linking the extension COM objects to ksproxy? The examples I have seen all seem to have an exact correspondence between one propertyset GUID in the minidriver with one custom interface and one property page. Is this always the case? Are the following alternatives possible: 1) A custom interface but with no associated property set? 2) Multiple custom property pages associated with a single property set? 3) A single propertyset with any number of interfaces and property pages hung off it? These questions reflect uncertainty about my ability to implement my current thinking which is: 1) Add a one or more propertyset GUIDs to the minidriver to implement the custom aspects of the camera. 2) Have a single custom COM interface in usermode to permit programatic access to those aspects. 3) Have one or more property pages to permit amcap etc to access to aspects. These property sheets would be implemented by using the custom inteface. Regards, Tom Udale Tag: CreateFile gives error 5 (Access is denied) Tag: 34403

    - Device could not start. I have a PCI driver for our custom I/O board. I generated the device driver with Walter's wizard. I modified the Toaster class installer for our device. I used a combination of the DDK inf generator and existing inf files. It looks like the driver worked just fine for a couple of months. Now, when I have one PCI card in the system, the device manager reports: This device cannot start. (Code 10) I can power down the machine, add a second card to the same bus segment, and both cards work fine when I power the system on. Where should I start to look?

    - Interrupts in PCMCIA device driver Hi, I have been struggling with this problem for some time, so any help from someone who has written a PCMCIA device driver would be greatly appreciated! I have written a working Win2K device driver for a PCI device, and am now writing a device driver for the PCMCIA version of the device (some code included below). My driver does not receive interrupts although the call to IoConnectInterrupt() succeeds. I have gone through the PSCR smartcard device driver code in the DDK samples. I am also familiar with the DisabeISAToPCIRouting registry setting - didn't make a difference in my case.

    - a question about win2000 ddk PORTIO sample!!!!!! I use win2k DDK to build the PORTIO sample in DDK successfully. But something is wrong when I use the gpdread and gpdwrite to test the driver. I use command line "GpdWrite -b 1 2" to write the number 2 to assigned 'base port address + 1', and then "GpdRead -b 1 "to read out. But the number read out is always 0xFF. I also tested writing a number every 1000 milliseconds and reading every 600 millisecond, but the read-out number kept 0xFF. what does the sample mean? could you tell me why? Softice driver suite(driverworks) contains similar sample, things are same. ____________________________________________________________________________ _________________________ Test OS: win2000 server Develop Environment: win2k ddk, visual studio 6.0 sp5 Tag: CreateFile gives error 5 (Access is denied) Tag: 34386

    - Loading filter driver during OS install I have a upper device filter driver that I need to load during install (ie. Hit F6 for scsi drivers). I was wondering if this has been done (I'm sure it has) and how to do it. I wonder about whether the txtsetup.oem actually loads and parses the inf early in the setup or not, and how you would actually code up the txtsetup.oem. Do you need to need to include a copy of the driver that your filtering (and it's inf) on your driver disk as well, or will this land from the media in time to be present when the filter driver's inf is parsed. -Dan Tag: CreateFile gives error 5 (Access is denied) Tag: 34383

    - Palettes and kernel-streaming driver (USBCAMD2) Hello, I am writing a USB camera mini-driver using USBCAMD2. I have the basic driver working, but need to get the video into the desired format for proper viewing in DirectShow. The video is 8-bit grayscale, and is interlaced (I receive two fields in one "frame" from the camera and interlace them in the CamProcessRawVideoFrameEx () function in my minidriver. They are displayed on the screen using RGB8 (8-bit color.) I would like to know how I can describe (or set somehow) the color palette as a grayscale palette. I've tried converting to RGB24 in the minidriver and replicating the 8-bit pixel value that I receive from the camera in the RGB fields. This works, but is so slow that I'm dropping frames. Any suggestions or hints would be appreciated. Sincerely, Howard M. Harte ======================== Harte Technologies, LLC.

    - HP deskjet on Windows XP The driver for this printer is included in WinXP and installs okay when plugging in the printers USB cable. My problem is that on the paper size list there is no "custom" size as refered to in the manual. I want to print on 3X5 index cards which is also not on the list. Even if I select a larger card like 4X6 and set margins to reduce it to 3X5 size it prints outside the margins. HP says I will have to wait for them to update the driver.

    - How does windows handle PCMCIA Ok, I really need to know how windows 2000/XP handles the insertion of a PCMCIA card. What I have discovered with my card is that occasionally (4-5%) of the time it works (I have found that in this case card enable is activated) and the rest of the time it fails (card enable is not activated). This only occures though within the VideoMiniport drivers. The PnP Functional Driver I wrote does not seem to have this problem. So if anyone can tell me/point me how exactly windows handles insertion or how the Videominiport deals with it, I wolud greatly appreciate it. -- Brian V.

    - Visual Studio library path size limit I have a project which takes quite a lot of library paths, due to our environment setup. The problem now is that the line in the *.dsp filefor the linker is more than 4Kb long. Is there a limit on how long the line may be? I mean the # ADD LINKER32 <linkeroptions> in the dsp file. When I paste in the project file all the library paths then Visual Studio can compile it, but when I exit the project VC asks me to safe the changes to the project file and when I try to reload the project the line is crippled. Any ideas how to circumvent this size limit? I tried to spread the line over several lines which worked, but as soon as I change something in the settings Visual Studio will rewrite the dsp file and create the long line again. -- Gerhard Gruber Für jedes menschliche Problem gibt es immer eine einfache Lösung: Klar, einleuchtend und falsch.

    - VideoDriver and PCMCIA Function Configuration Registers Is there a way to access the Function Configuration Registers is a VideoMiniport driver. I can access (somewhat) I/O memory (given to me through VideoPortGetAccessRanges) but nothing comes for the FCR's. Of course, given that the card gets mapped to ISA (determined from the VIDEO_PORT_CONFIG_INFO) I may not need to access the Registers. Also, any one who is famialar with the internal workings of the VideoPort functions, what PCMCIA Configuration Registers are needed for successful operation. Currently we only support a subset of the registers PC-Card requires because we are a CF-Card, could this cause a problem? Thanks in advance, yet again. -- Brian V.

    - How can I get selected option items from property sheet page? Hi. I am developing a printer driver which prints any document to an image file. I am using Unidrv.dll and Win2000 DDK sample Oemui.dll. There is one more component, rendering plug-in. I added a new property sheet page and a option item using a method in Oemui.dll like below. // source code // HRESULT hrOEMDocumentPropertySheets(PPROPSHEETUI_INFO pPSUIInfo, LPARAM lParam, IPrintOemDriverUI* pOEMHelp) { LONG_PTR lResult; ............ // Do action. switch(pPSUIInfo->Reason) { case PROPSHEETUI_REASON_INIT: { DWORD dwSheets = 0; PCBUSERDATA pUserData; POEMUIPSPARAM pOEMUIParam = (POEMUIPSPARAM) pPSUIInfo->lParamInit; HANDLE hHeap = pOEMUIParam->hOEMHeap; POEMDEV pOEMDev = (POEMDEV) pOEMUIParam->pOEMDM; COMPROPSHEETUI Sheet; DLGPAGE PageProp; // Init property page. memset(&Sheet, 0, sizeof(COMPROPSHEETUI)); Sheet.cbSize = sizeof(COMPROPSHEETUI); Sheet.Flags = CPSUIF_UPDATE_PERMISSION; Sheet.hInstCaller = ghInstance; Sheet.pCallerName = GetStringResource(hHeap, ghInstance, IDS_NAME); Sheet.pHelpFile = NULL; Sheet.pfnCallBack = OEMDocUICallBack; Sheet.pDlgPage = CPSUI_PDLGPAGE_ADVDOCPROP; Sheet.cOptItem = 1; Sheet.IconID = IDI_CPSUI_PRINTER; Sheet.pOptItemName = GetStringResource(hHeap, ghInstance, IDS_SECTION); Sheet.CallerVersion = 0x100; Sheet.OptItemVersion = 0x100; // Init user data. pUserData = (PCBUSERDATA) HeapAlloc(hHeap, HEAP_ZERO_MEMORY, sizeof(CBUSERDATA)); pUserData->hComPropSheet = pPSUIInfo->hComPropSheet; pUserData->pfnComPropSheet = pPSUIInfo->pfnComPropSheet; pUserData->pOEMUIParam = pOEMUIParam; Sheet.UserData = (ULONG_PTR) pUserData; // Create OptItems for page. Sheet.pOptItem = CreateOptItems(hHeap, Sheet.cOptItem); // Initialize OptItems Sheet.pOptItem[0].cbSize = sizeof(OPTITEM); Sheet.pOptItem[0].Level = 1; Sheet.pOptItem[0].Flags = OPTIF_COLLAPSE; Sheet.pOptItem[0].pName = GetStringResource(hHeap, ghInstance, IDS_SECTION); Sheet.pOptItem[0].Sel = pOEMDev->dwDriverData; Sheet.pOptItem[0].pOptType = CreateOptType(hHeap, 3); Sheet.pOptItem[0].pOptType->Type = TVOT_3STATES; Sheet.pOptItem[0].pOptType->pOptParam[0].pData = GetStringResource(hHeap, ghInstance, IDS_TIF); Sheet.pOptItem[0].pOptType->pOptParam[1].pData = GetStringResource(hHeap, ghInstance, IDS_JPG); Sheet.pOptItem[0].pOptType->pOptParam[2].pData = GetStringResource(hHeap, ghInstance, IDS_BMP); Sheet.pOptItem[0].pOptType->pOptParam[0].IconID = IDS_TIF; Sheet.pOptItem[0].pOptType->pOptParam[1].IconID = IDS_JPG; Sheet.pOptItem[0].pOptType->pOptParam[2].IconID = IDS_BMP; Sheet.pOptItem[0].pOptType->Count = 3; // Add property sheets. lResult = pPSUIInfo->pfnComPropSheet(pPSUIInfo->hComPropSheet, CPSFUNC_ADD_PCOMPROPSHEETUI, (LPARAM)&Sheet, (LPARAM)&dwSheets); } break; ............ } pPSUIInfo->Result = lResult; return S_OK; } And it works well. There was a newly added property sheet page in printing dialog. I'd like to let the user select an output file format(bmp, tif, etc.) through the property sheet page(using TVOT_3STATES in above source code) and add some more option items in the same sheet page. The problem is that I don't have any idea how I can get the results of what user selected through the option items in the property sheet page. There are some answers to similar question but not enough to understand how and what. I'd like to use the selected options in rendering plug-in module. Does anyone know the solution to this question? If possible, please show me some sample source codes. Or explain in detail. Thanks in advance. Tag: CreateFile gives error 5 (Access is denied) Tag: 34333

    - Multiple IRP requests from one driver to another Hi All, My driver uses standard serial port driver. It set RTS signal and wait for CTS signal change. 1. Driver send IRP to serial port driver with control code IOCTL_SERIAL_WAIT_ON_MASK and doesn't wait for it. 2. Driver send IRP to serial port driver with control code IOCTL_SERIAL_SET_RTS and wait for it. 3. Driver wait for first IRP through the Event, passed to IoBuildDeviceIoControlRequest. This approach does not work. User mode application is locked and driver can not be unloaded. May be the IoSetCompletionRoutine is solution ? Thanks.

    - PrintProcessor Installation problems on Win98SE/Me Hello All, I developed a minidriver and relative Print Processor for our Pos printer product on Win98Se and Me. Then I wrote a .INF file for install the package. The printer is installed correctly, but it doesn't catch my PrintProcessor. All the files (minidriver + printproc.) are copied in C:\WINDOWS\SYSTEM. But when I go to check with 'Regedit', what the installation has written into registry, I can see that no subkeys for my printprocess are been made in: HKLM\System\CurrentControlSet\Control\Print\Environments\Wi ndows 4.0\Print Processors; while the subkey of my printer is present, and into it the field "Print Processor" has "WinPrint" as value. By the way, I started to develop my PrintProcessor from Win98 DDK , modifing the Winprint sample included in src\printers\spooler' subdirectory. And, I took infos for insert printprocess from W98 DDK documentation. Where is my mistake? Somebody have any idea? Please, Help me. Below I inserted my INF file. TIA Giandomenico.

    - How can I get the results from newly added property sheet page? Hi. I am developing a printer driver which prints any document to an image file. I am using Unidrv.dll and Win2000 DDK sample Oemui.dll. There is one more component, rendering plug-in. I added a new property sheet page and a option item using a method in Oemui.dll like below. // source code // HRESULT hrOEMDocumentPropertySheets(PPROPSHEETUI_INFO pPSUIInfo, LPARAM lParam, IPrintOemDriverUI* pOEMHelp) { LONG_PTR lResult; ............ // Do action. switch(pPSUIInfo->Reason) { case PROPSHEETUI_REASON_INIT: { DWORD dwSheets = 0; PCBUSERDATA pUserData; POEMUIPSPARAM pOEMUIParam = (POEMUIPSPARAM) pPSUIInfo->lParamInit; HANDLE hHeap = pOEMUIParam->hOEMHeap; POEMDEV pOEMDev = (POEMDEV) pOEMUIParam->pOEMDM; COMPROPSHEETUI Sheet; DLGPAGE PageProp; // Init property page. memset(&Sheet, 0, sizeof(COMPROPSHEETUI)); Sheet.cbSize = sizeof(COMPROPSHEETUI); Sheet.Flags = CPSUIF_UPDATE_PERMISSION; Sheet.hInstCaller = ghInstance; Sheet.pCallerName = GetStringResource(hHeap, ghInstance, IDS_NAME); Sheet.pHelpFile = NULL; Sheet.pfnCallBack = OEMDocUICallBack; Sheet.pDlgPage = CPSUI_PDLGPAGE_ADVDOCPROP; Sheet.cOptItem = 1; Sheet.IconID = IDI_CPSUI_PRINTER; Sheet.pOptItemName = GetStringResource(hHeap, ghInstance, IDS_SECTION); Sheet.CallerVersion = 0x100; Sheet.OptItemVersion = 0x100; // Init user data. pUserData = (PCBUSERDATA) HeapAlloc(hHeap, HEAP_ZERO_MEMORY, sizeof(CBUSERDATA)); pUserData->hComPropSheet = pPSUIInfo->hComPropSheet; pUserData->pfnComPropSheet = pPSUIInfo->pfnComPropSheet; pUserData->pOEMUIParam = pOEMUIParam; Sheet.UserData = (ULONG_PTR) pUserData; // Create OptItems for page. Sheet.pOptItem = CreateOptItems(hHeap, Sheet.cOptItem); // Initialize OptItems Sheet.pOptItem[0].cbSize = sizeof(OPTITEM); Sheet.pOptItem[0].Level = 1; Sheet.pOptItem[0].Flags = OPTIF_COLLAPSE; Sheet.pOptItem[0].pName = GetStringResource(hHeap, ghInstance, IDS_SECTION); Sheet.pOptItem[0].Sel = pOEMDev->dwDriverData; Sheet.pOptItem[0].pOptType = CreateOptType(hHeap, 3); Sheet.pOptItem[0].pOptType->Type = TVOT_3STATES; Sheet.pOptItem[0].pOptType->pOptParam[0].pData = GetStringResource(hHeap, ghInstance, IDS_TIF); Sheet.pOptItem[0].pOptType->pOptParam[1].pData = GetStringResource(hHeap, ghInstance, IDS_JPG); Sheet.pOptItem[0].pOptType->pOptParam[2].pData = GetStringResource(hHeap, ghInstance, IDS_BMP); Sheet.pOptItem[0].pOptType->pOptParam[0].IconID = IDS_TIF; Sheet.pOptItem[0].pOptType->pOptParam[1].IconID = IDS_JPG; Sheet.pOptItem[0].pOptType->pOptParam[2].IconID = IDS_BMP; Sheet.pOptItem[0].pOptType->Count = 3; // Add property sheets. lResult = pPSUIInfo->pfnComPropSheet(pPSUIInfo->hComPropSheet, CPSFUNC_ADD_PCOMPROPSHEETUI, (LPARAM)&Sheet, (LPARAM)&dwSheets); } break; ............ } pPSUIInfo->Result = lResult; return S_OK; } And it works well. There was a newly added property sheet page in printing dialog. I'd like to let the user select an output file format(bmp, tif, etc.) through the property sheet page(using TVOT_3STATES in above source code) and add some more option items in the same sheet page. The problem is that I don't have any idea how I can get the results of what user selected through the option items in the property sheet page. There are some answers to similar question but not enough to understand how and what. I'd like to use the selected options in rendering plug-in module. Does anyone know the solution to this question? If possible, please show me some sample source codes. Or explain in detail. Thanks in advance. Tag: CreateFile gives error 5 (Access is denied) Tag: 34322

Hi,

I am new to the Windows driver development. I am writing a
filter driver for an USB mouse using DDK's sample code.
I want to have the user application to communicate with
this driver.

In the driver, I have registered the interface using a GUID
and enabled it.
From the application, I will enumerate through the device
interfaces and get the device path.
I am using this device path to "CreateFile".

file = CreateFile ( deviceInterfaceDetailData->DevicePath,
GENERIC_READ | GENERIC_WRITE,
0,
NULL, // no SECURITY_ATTRIBUTES
structure
OPEN_EXISTING, // No special create
flags
0, // No special attributes
NULL);/*

Unfortunately this call failed with error 5 (Access is denied).

Can anybody tell me what might be the problem. Am I missing
anything here.

TIA,
Raghav
