    - Stream devices identification` Hello, All. I am working on DirectShow application, which works with stream devices. Application have a list of these devices to provide to user possibility to choose device he(she) wants. The probem is the follow: the device can be connected to the system when application is executed and I need to add new device into the list. I have hooked WM_DEVICECHANGE message and then enumerate all devices I need via ICreateDevEnum and IEnumMoniker interfaces. But I need to know which devices are already in the my list and which of them are new. The questions are: 1.There is any documented way to understand that two IBaseFilter interfaces points to the same device? 2. Do I can use string returned by the IMoniker::GetDisplayName method for this purpose? -- Andrey Tag: How to set WEP Keys programmatically Tag: 27856

    - Reading data from USBPRINT stalls the pipe Hi, I have managed to get a user-mode app talking directly to an instance of Microsoft's USBPRINT driver. I can write to the printer and get the Centronics emulation status just fine. My problem is that, when I want to read data from the printer, I must specify the exact number of bytes the printer will send in the ReadFile() call. If I specify more bytes, the call will hang - but this is normal. If I specify less bytes, this is what happens: -> The bytes requested *are* read, the ReadFile() call fails indicating zero bytes read, GetLastError() returns 23 and the URB returns with status 0xc000000c (USBD_STATUS_BUFFER_OVERRUN); -> Further ReadFile() calls fail with zero bytes read, no data is read, GetLastError() returns 23 and the URB returns with status 0xc0000030 (USBD_STATUS_ENDPOINT_HALTED). It seems that USBPRINT is stalling the IN endpoint when I request less bytes than those available at the printer. This happens under Win2000 and Win98 and I have tested two printers from different vendors. Question: Is there any way of clearing the stalled pipe or of reading an unknown amount of data through USBPRINT? Thank you, Aspas PS: I am using SnoopyPro to see the URBs exchanged.

    - Communication wire with test system We are debugging our drivers using a dual-system configuration (one for development and one for testing) connected using a serial cable. Our development environment is Windows 2000 Professional, but the target systems are Windows 2000 Profession/Server/Advanced Server, Windows XP Home/Professional and Windows 2003. We are always looking for ways to improve our productivity during the testing phase. One bottleneck that has been identified is the use of the serial cable. It has been suggested that a 1394 (firewire) port would enable faster transfers and debugging, but there are some suggestions that this is not available with Windows 2000. Will installing a 1394 card on both the develoment and test system permit faster debugging? Can it be used with Windows 2000? If not, what prevents it from being used? If I cannot use 1394, is there another mechanism that would be faster than the serial cable? -Ken Tag: How to set WEP Keys programmatically Tag: 27839

    - Directshow support for MPEG-4 streaming Hello all, In DDK there are KSDATARANGE structures for MPEG1, MPEG2 and even MPEG2TS . But there is no structure which supports MPEG4. I built a filter with a output pin with KS_DATRANGE_VIDEO structure with Major type : KSDATAFORMAT_TYPE_STREAM and subtype as MP42. But when i rendered the pin its saying no inteermidiate filters not available. There are directshow filters like Mpeg4 Decode DMO, Mpeg43 Decode DMO , Mpeg4s Decode DMO and Microsoft MPEG-4 Video compressor. I want to know the major and subtypes supported by these filters. So that i can configure my filter pin for that format. Even i tried with custom MPEG-4 filtes from Elecard, DivX and Dicas. Still i am not able build the graph. So i have following questions: 1. Is there any support for MPEG4 streaming in directshow. 2. Which data range structure should be used for MPEG4 SL streaming. 3. What should be the major and subtype of the pin. 4. Is there anything extra should be mentioned in the data range structure so that directshow should understand and add mpeg4 related intermidiated filters. Any inputs and pointers on above queries are highly appriciated. Waiting for ur reply. - Regards, Rafi Maniyar Tag: How to set WEP Keys programmatically Tag: 27832

    - scsi timeout at boot Microsoft Knowledge Base Article 139357 describes how some scsiport drivers can produce a timeout message when the windows OS is booting. It describes that the timeout is caused by a MODE_SENSE command being issued by the scsidisk.sys driver with a timeout value on the I/O being 0. It describes the problem as being only applied to windows NT 3.5 (Workstation/Server). My problem is that the driver I'm currently working with is exhibiting the exact same problems as described by this article but on the windows NT/2000 environments. Is it just that this article isn't up to date and my timeouts are symptomatic of something else. The timeouts only occur during the OS boot and the driver and the hardware function normally outside of this. Can anyone offer some insight?

    - 1394 virtual device I have a medical device which receives Async commands from an App running on Windows2000. Windows 2000 App used modified 1394diag driver and Microsoft Windows stack. Now I want to move to Windows XP and Microft XP Windows 1394 stack and driver similar to 1394diag. Do I need 1394 virtual device. (like 1394vdev.sys). When I have actual 1394 device connected, why should I again create 1394 virtual device. Should I make any changes in INF and configRom of device. For one 1394 device to talk with XP, do I need two drivers, virtual and actual driver. Can someone make me understand this? Where can I find info for this?

    - WriteFile(...) to USB HID: why does this call hang my client application ? Hi, I'm experimenting with some home-made HID-class USB device. All is well with the ReadFile calls to read report. The queuing and blocking mechanism is clear to me. But I'm stumbling with some issues when sending reports with WriteFile. I never get any error results ( WriteFile() returns a non-zero value ), but sometimes the call just doesn't return, and requires me to kill my application. Any idea why this would be happening ? Reducing the frequency of calls to WriteFile seemed to help a bit, but did not solve the issue. My calls to WriteFile always follow a successful call to ReadFile, and I do not see what else I could/need to do to avoid overflowing the output queue. So what is going wrong ? Any idea about something I could be trying ? Thanks in advice for any hint or directions, Ivan NB: I'm running Win2k SP 3 -- Ivan Vecerina, Dr. med. <> http://www.post1.com/~ivec Tag: How to set WEP Keys programmatically Tag: 27795

    - symbolic link and IoGetDeviceObjectPointer Hello all, I have a problem with drivers calling each other. There are 3 drivers. Two of those drivers need to ask driver nr 1 some things. Nr 1 does the following in his AddDevice method: RtlInitUnicodeString(&devname, L"\\Device\\NAME"); RtlInitUnicodeString(&win32DeviceName, L"\\DosDevices\\NAME"); IoCreateSymbolicLink( &win32DeviceName, &devname); Nr 2 and 3 then try: RtlInitUnicodeString(&devName, L"\\Device\\NAME"); status=IoGetDeviceObjectPointer(&devName, FILE_ALL_ACCESS, &fileObj, &devObj); The problem is that nr 2 does this first (but definitely after the addentry method of nr 1), but always gets c0000e as error code (device not found). Nr 3 first has to load some files and asks stuff to nr 1 later (and he IS successfull). In other words: there seems to be a delay between the IoCreateSymbolicLink and the time when the driver can actually attempt to get a handle to it. (Note: I'm a newbie, so forgive me if I say stupid things :-) Is this true? Can I alter the loading order, so nr 2 is called after nr 3 (I don't think so, both are PnP drivers and I think I read you can't specify a load order)? thx in advance for all help, crimson13 Tag: How to set WEP Keys programmatically Tag: 27783

    - Wakeup problem with PCMCIA card I am writing a WDM driver for a simple PCMCIA card and testing it under Windows 2000/SP3. The driver is based on a framework created with Walter Oney's WDM Driver Wizard. In particular, the Power handling functions are more or less unchanged. My problem is, that when the system wakes up from standby mode, Windows thinks that the hardware has changed and starts the New-Hardware-Wizard. The driver appears to complete the processing of the power IRPs, but then receives a IRP_MN_SURPRISE_REMOVAL request, following which the driver is unloaded. The New-Hardware-Wizard indicates that it has detected a device named MTD-0002. I have been advised that this probably means that Wihdows is unable to read the Card Information Structure (CIS) on the PCMCIA card, but I can see no reason why this would be the case. I have set D3Latency parameter to 1000 (100ms) which should be more than enough. On inserting the card into the slot, Windows never has any difficulty reading the CIS, so I don't see why there should be a problem when it is powered up on leaving standby mode. Does anybody have any idea what could be causing this effect? I would be grateful for any help. Thanks in advance Phil (By the way, this is newly developed hardware and the error could be in the CIS. It is not a big problem for us to reprogam this memory.) Tag: How to set WEP Keys programmatically Tag: 27775

    - how to display bitmap on screen constantly? Hi, I'm trying to find a way to display a bitmap on the top- right portion of the screen at all times, even when an application using directx in full-screen mode is in use. Can this be accomplished using display filter drivers? I was thinking of writing a driver that would simply map the bitmap data to the screen along with the rest of the screen data. So, could a filter driver be installed "below" GDI and Directx that would map the bitmap regarless of wich interface(gdi or directx) is in use? And if so, since GDI and directx are different components that each communicates directly with the video adapter (as I understand it), will the driver have to be device specific? Anyway, if u guys know a way to accomplish this bitmap mapping whitout using drivers i'll be more than happy to hear it. Tag: How to set WEP Keys programmatically Tag: 27768

    - Enable/Diable Device Driver from Non-Admin account In our Video Conferencing systems, we have multiple propritary drivers running on the system and also our system works with different third party Conferencing Devices. Obviously differnt drivers for variety of HW devices are running on the same system. Our recent version of HW is getting problems with one of HW that is colloborated with our unit. Then I played with different drivers and finally I found a way to make it work. Disable the HW unit driver before reboot and enable after the system booted completely using Windows ddk api from one of test app. But the Microsoft documentation is expalaining that these APIs for Enable/Disable, SetupDiChangeState, is only for Administrator group. Is there any way to disable / Enable the Drivers when we login as a Non-Admin also. Can somebody to help to solve this problem. If I am following the wrong way, Can you update me the proper way to solve this issue. Thank You Murthy Tag: How to set WEP Keys programmatically Tag: 27743

    - sub-optimal performance through CardBus controllers on Windows Problem Statement - The Windows XP and 2000 driver in the OS for CardBus controllers are not programmed for optimal throughput or performance. Observations - We have a Network adapter that runs roughly the same speeds as a Fast Ethernet NIC. - We can sustain data rates in the Tx and Rx directions (simultaneously) of roughly 80Mbps through the NIC and Ndis driver across PCI. - When running through a Cardbus controller programmed by Windows (with the Windows provided Cardbus controller drivers) we see Rx rates of approximately 78 Mbps. Tx rates top out at roughly 38 Mbps. - We have noticed that the Cardbus bridge is NOT programmed for optimal performance, even though the PCI configuration space shows settings that the CardBus controller driver seems to be ignoring. For example, burst read and write were set in the PCI config space for the card (MBURSTDN and MBURSTUP) but the CardBus controller is NOT programmed to burst by the Windows OS CardBus controller driver. - When we manually change the cardbus controller to enable bursting, the Tx performance improves dramatically. Questions. 1. Can the Network card do anything to influence the Windows Cardbus controller driver to enable Burst read and write ? 2. Are there other settings the Network card can use to ensure the Cardbus controller is set for optimal performance? 3. The Fast Ethernet NICs must have run into this same problem already. We see that that off the shelf Fast Ethernet NICs also are not running anywhere near optimal performance / throughput. We see simliar rates for Tx and Rx on with Fast Ethernet Cardbus NICs. We can program the CardBus controller maually to dramtically improve the performance but we still do not see what we would expect (90+ Mbps in both directions). Below are some detailed notes about our investigation and characterization of the problem. We are doing performance characterization on our Cardbus NIC, which has a PHY throughput roughly equivalent to a Fast Ethernet NIC (approximately 100 Mbps simultaneously for Tx and Rx). But, we are seeing some performance issues, while transferring data across the Cardbus interface. We have not been able to get the Cardbus interface, on any laptop to transmit data at rates higher than 37 Mbps and receive data across the Cardbus interface at rates higher than 78 Mbps. Also, there are some laptops where the upstream througput is as low as 3 Mbps and the downstream throughput only 7 Mbps. The throughput seems to vary with the part no. of the Cardbus Controller, being used in the laptop. Following is a list of observations that we made while running the tests, with each laptop: 1. Sony Vaio Laptop running Win2k with RICOH 5c475 II Cardbus controller: This laptop showed a throughput of 37 Mbps upstream and 78 Mbps downstream, when we transfered data at roughly 100 Mbps at the PHY layer. 2. Dell Latitude laptop running WinXP with the TI PCI-1420 Cardbus controller: This laptop showed a throughput of 37 Mbps both upstream and downstream, when we transfered data at roughly 100 Mbps at the PHY layer. 3. IBM Thinkpad running WinXP with the TI PCI-1510 Cardbus controller: This laptop showed a throughput of just 3 Mbps upstream and 7 Mbps downstream, when we transfered data at roughly 100 Mbps at the PHY layer. When we monitored the Cardbus transactions on a logic analyzer, we saw that although the controller was allowing DMA bursts, it was issueing a lot of retries, to the device. 4. If we replace the NIC with an out of the box Fast Ethernet NIC, we see strikingly similar numbers in all cases. All the above setups are running the standard Cardbus controller drivers which came with the Operating System and we are running standardout of the box NDIS Miniport drivers, to drive our NIC. So, the question is, how can we get the Cardbus controller drivers on each platform and OS, to configure the controller correctly, to allow maximum throughput across the Cardbus interface ? Programming the TI Cardbus controller manually Since, the datasheets for the RICOH controllers, are not available online, we looked at the Cardbus configuration registers, of only the TI controllers. Following was the default configuration on both the TI controllers on the WinXP laptops: 1. The MBURSTDN and MBURSTUP bits (bits 15 and 14) were set in the System Control Register (PCI Config space offset 80h), for bursts, both for Read and Write transactions. 2. The POSTEN bit (bit 10) in the Bridge Control Register was set, enabling write posting, which is recommended for good performance while bursting. 3. The Latency Timer settings are different on the controllers: TI Controller Latency Timer Cardbus Latency (Secondary Bus Latency) PCI-1420 20 20 PCI-1510 40 B0 4. The KEEPCLK bit (bit 1) in the System Control Register was cleared, which implies that usage of the CLKRUN protocol was enabled, although we implement the CCLKRUN# pin as a NO-CONNECT on our device, since it was decided not to support this protocol. I tried running the tests, after toggling this bit, so that the Cardbus clock is always kept active and is not throttled using the CLKRUN# protocol, but that did not improve the performance, in any way. 5. The PCIRETRY and CBRETRY bits (bits 7 and 6), in the Retry Status Register, are set, indicating that PCI and Cardbus retry timeout is enabled. Following was the configuration of our device: MIN_GNT = 18 MAX_LAT = FF Latency Timer = F8 While running WinXP, we got a similar low throughput of 19 Mbps. Subsequently, looking at the Cardbus Controller registers and we found that again the MRBURSTUP bit was not set by the XP CB controller driver. So, after setting this bit, manually, I was able to acheive an upstream throughput of 51 Mbps. This strongly suggests that the Microsoft WinXP Cardbus controller drivers are not optimized setting the Controller hardware for optimum performance basedon the parameters of the CardBus cards plugged into the bridge. We are wondering if other NIC vendors would have run into the same issues on Windows and got some fixes from Microsoft. Following, we were able to achieve a new performance high on our Cardbus NIC using the Dell Latitude laptop with the TI PCI-1420 Cardbus controller. We were able to acheive 46 Mbps upstream and 79 Mbps downstream, while trying to transmit packets at roughly 100 Mbps. So, we are almost at par with the Cardbus Fast Ethernet performance, seen on the various laptops. The differences this time are: 1. This NIC is programmed with a new EEPROM image which programs the PCI MIN_GNT, MAX_LAT and the latency timer to values optimized for the maximum throughput. 2. Before we started this test, we made sure that the PCI latency timer values on all the intermediate PCI-PCI bridges and PCI-Cardbus controller, was set to the max possible value of 0xF8 (since I found that the latency timer values on some of the intermediate bridges was set to zero, by default, which might have inhibited the Cardbus performance). --- Larry Cawley Airgo Networks, Inc. 636 458 1462 <mailto:LarryCawley@AirgoNetworks.com> Tag: How to set WEP Keys programmatically Tag: 27741

    - TextOut Hello , I have a strange problem which I have encountered in my code ,The DrvTextOut Method of my driver fails when tested with speedy , on further debugging I found out that it fails in the pcfallocatecachedFont method and at these lines // swap a cached font (using LRU method) pFCNode = ppdev->pFC->pUsedList.pPrev; //Change status into uncached pFCNode->pfo->pvConsumer = NULL; //clear glyph tag pjFCTag = (PBYTE) pFCNode->pjTag; for (i = 0; i < FC_MAX_GLYPH_ID; i += 4) { *(PULONG) pjFCTag = 0; pjFCTag += 4; } //for Now the problems are as follows: 1.The driver doesn't break at the same position all the time sometimes it breaks in the for loop some times just after the font is swapped .it also doesn't break for a specific font id it just breaks randomly. 2.The same driver is working fine with speedy on a Pentium 4 machine with 256 mb ram whereas the orignal machine is intel celeron with 196 mb ram. Now my doubts are : 1.Can this be because of the CPU speed , I think it might be a swapping problem because it is giving me a page fault in non paged area.if it is how can I make changes in the code to make it compatiable for the celeron platform. 2.The replacement algorithm I have used is incorrect,I should not use LRU . Please advise , as I am not clear if I am on right tracks.for further refrece I am attaching the pcfAllocatecachedfont method.

    - why it doesnt work?????? i have got OID_802_11_STATISTICS's value and i can display correctly, i put the follow function in the OnTimer event. however, all of the value(transmitCount and receiveCount) i got is zero.(my thought is to display the number of transmit and received packages looks like the network status) void OnTimeer(XXXXX) { IoctlNdisQueryTest(lpAdapterName) } DWORD IoctlNdisQueryTest(LPCTSTR lpAdapterName) { NDIS_802_11_STATISTICS OidData; DWORD nResult, ReturnedCount = 0; ZeroMemory( &OidData, sizeof(OidData)); OidData.Length = sizeof(OidData); nResult = Test_IoctlNdisQueryGlobalStats (lpAdapterName,OID_802_11_STATISTICS,OidData,sizeof (OidData),&ReturnedCount); if( nResult != ERROR_SUCCESS ) sprintf(sLabel,"%s","The driver unsupported"); else sprintf(sLabel,"%I64d,%I64d", OidData.TransmittedFragmentCount.QuadPart, OidData.ReceivedFragmentCount.QuadPart); Tag: How to set WEP Keys programmatically Tag: 27708

    - kernel driver refuses to run in safe boot I'm trying to write a very little SERVICE_KERNEL_DRIVER driver, which is supposed to run during safe boot. My current driver is as good as empty, I can successfully start & stop it during a normal (non safe) session. Also it boots up in a normal (non safe) session when being installed as SERVICE_SYSTEM_START. Everything looks just fine. But during safe boot XP suddenly is not able to load the driver. It tries to load it (I've added it to the safe boot registry keys), but it fails. The XP event log sais, XP was not able to load my driver, but it doesn't tell me why. If I check out the properties page of my driver (via device manager) after a safe boot I can see that it is not running. If I then try to manually start it, the dialog freezes for about 5 seconds, but the driver still does not run. What do I have to change to make my driver run successfully in a safe boot? Thanks! P.S: I tried to add power, pnp and wmi handlers, but that didn't help, either. Maybe I implemented them incorrectly, though. ============================================================ #include <ntddk.h> void UnloadDriver(PDRIVER_OBJECT DriverObject) { IoDeleteDevice(DriverObject->DeviceObject); } NTSTATUS DummyIrpHandler(PDEVICE_OBJECT DeviceObject, PIRP Irp) { Irp->IoStatus.Status = STATUS_SUCCESS; IoCompleteRequest(Irp, IO_NO_INCREMENT); return STATUS_SUCCESS; } NTSTATUS DriverEntry(PDRIVER_OBJECT DriverObject, PUNICODE_STRING RegistryPath) { PDEVICE_OBJECT devObj; UNICODE_STRING name; RtlInitUnicodeString(&name, L"\\Device\\MtsUpd"); IoCreateDevice(DriverObject, 4, &name, FILE_DEVICE_UNKNOWN, 0, FALSE, &devObj); DriverObject->DriverUnload = UnloadDriver; DriverObject->MajorFunction[IRP_MJ_CREATE] = DummyIrpHandler; DriverObject->MajorFunction[IRP_MJ_CLOSE] = DummyIrpHandler; return STATUS_SUCCESS; } Tag: How to set WEP Keys programmatically Tag: 27707

    - scsi miniport HwStartIo() IRQL if no interrupts in a scsi miniport driver for a virtual HW(obviously no HW interrupts), if i set the PORT_CONFIGURATION_INFORMATION -> BusInterruptVector = 0; for findadapter and HW_INITIALIZATION_DATA -> HwScsiInterrupt = NULL can i be gauranteed that my HwStartIo() and/or HwTimer()will be called at DISPATCH_LEVEL(atleast)/PASSIVE_LEVEL? because i cant think of what DIRQL can SCSIPORT assume before calling into me? KeSynchronizeExecution() requires interrupt# question 2 ------------- since HwStartIo() can be called at DIRQL what syncronization mechanisms are available inside this routine to share data with a PASSIVE_LEVEL thread? even spinlocks are useless > DISPATCH_LEVEL. i am prepared to use any NTDDK only kernel functions thx alex Tag: How to set WEP Keys programmatically Tag: 27705

    - WinDDK Fails to Build Examples I've installed the winddk 3790, read the release notes and getting started guide, and attempted to build the examples but I've had no luck-- the build is silently failing. Executing 'build -cZ' from the command prompt spawned by "Windows 2000 Checked Build Environment" rapidly scrolls through all the example directories (much too fast to be building) and exits without errors. If I look into an example (i.e. src\general\portio) at the build log file, I see entries like the following: > Compiling c:\winddk\3790\src\general\portio\sys directory ************* > 'nmake.exe /c BUILDMSG=Stop. -i NTTEST= UMTEST= NOLINK=1 NOPASS0=1 386=1' > Bad command or file name Any ideas? The log output is identical for every example driver in the DDK. I'd expect building examples to "just work" but I'm not familiar enough with this environment to even begin to guess what is wrong. It should be mentioned that I had this exact error mode using a previous Win2K DDK, so I elected to grab the latest 2003 Server DDK in the hopes that the integrated compiler, etc, would make the effort easier.

    - ScatterGatherList Fails Hi, I am using GetScatterGatherList for doing Bus Master DMA. It fails with status = "STATUS_BUFFER_TOO_SMALL". I have called it 9 times, but only two times it passes. What is the reason for this status code ? Which buffer is too small ? Number of MapRegisters allocated is 8. The buffer size to be transferred is 5120, it spans to a maximum of 3 pages. The following is the function call Status = DeviceExtension->AdapterObject->DmaOperations->GetScatterGatherList( DeviceExtension->AdapterObject, DeviceObject, mdl, // IRP->MdlAddress DeviceExtension->CurrentVaddr, // MmGetMdlVirtualAddress(mdl) transferSize, // 8192 or 12298 (2 * PAGE_SIZE or 3 *PAGE_SIZE) (PDRIVER_LIST_CONTROL) AdapterListControl, DeviceExtension, bOperationType); // bOperation = TRUE for a write, FALSE for a read.

    - Paging file size problem for Win XP - Pro I upgraded my machine from Win XP-Home to XP-Pro. Everything is fine but the Virtual Memory problem - everytime I boot the machine, it keeps giving me the "low virtual memory" message. I have tried to use Start | Settings | Control Panel | System|Advanced |...| Virtual Memory Dialog to modify the Initial Size & Max Size values, it seems that it doesn't work; the allocated paging file size is always 0 even though I restart the machine.

    - [Q] USB Mass Storage Device IOCTL failure I'm developing a USB mass storage device with an additional functionality. There is no problem in locating the device's symbolic link, using SetupDiXXX functions. But if I try to DeviceIoControl() IOCTL_STORAGE_GET_DEVICE_NUMBER, IOCTL_SCSI_GET_INQUIRY_DATA, and other disk and storage control codes as well, after opening the device through CreateFile() with the following symbolic link name, it fails with the error code 50, which means ERROR_NOT_SUPPORTED. \??\USB#Vid_0c76&Pid_0005#0304281630200#{a5dcbf10-6530-11d2-901f-00c04fb951ed} To be more precise, my USB storage device supports Bulk-Only Transport protocol and announces itself as a SCSI transparent subclass device. If there is anybody who had ever stuck in this type of problem, please give me some clues for solving it. **** I have one more question. I'm in the position to develop hardware and software. So for now, I'm trying to compose a small program controlling a mass storage device of another manufacturer. If I'm to develop the firmware without relying on the USB controller customized to the specific application, do I have to write a firmware parsing all the SCSI command set? Or is there any documentation that specifies which part of the standard SCSI command set USB mass storage device spec supports? I'm afraid if I have to deal with a whole bunch of SCSI command set.

    - Problems sending named events to Driver Hi NG My driver has problems recieving a event from my user mode applikation. But there is no problems recieving the same event in my appilication from the device driver. Thia is what I do: In my DriverEntry i create the event with this: // Create event for user-mode processes to monitor RtlInitUnicodeString(&uszNotifyEventString, L"\\BaseNamedObjects\\AppEvent"); // Trying to create the event NotifyEvent = IoCreateNotificationEvent(&uszNotifyEventString, &NotifyHandle); if(NotifyEvent) { // Success KdPrint(("NotifyEvent event created with success\r\n")); // Clear it... KeClearEvent(NotifyEvent); } I get the handle to the event in my application like this: // Creating event. ITs created by the driver.. hEvent = OpenEvent(SYNCHRONIZE, FALSE, _T("AppEvent")); if(NULL == hEvent ) { return 0; } They both succed. My application then waits for the event: // The events used.. hEvents[0] = pService->HEndThread; byNumOfEvents++; hEvents[1] = hEvent ; byNumOfEvents++; dwWait = WaitForMultipleObjects(byNumOfEvents, hEvents, FALSE, INFINITE); if((WAIT_OBJECT_0 + 1) == dwWait) { // Set event again. Driver does not respond to this SetEvent(hEvent ); <----- No responds in my driver on this } When my driver signals the event ( KeSetEvent(NotifyEvent, 0, TRUE) ) my application is responding OK to the event But when my application sets the event my driver does not respond to it. // Setting event KeSetEvent(NotifyEvent, 0, TRUE); <--- My application responds to this KeResetEvent(NotifyEvent); // Waiting for the service to answer status = KeWaitForSingleObject(NotifyEvent, UserRequest, KernelMode, FALSE, &WaitTimeOut); // Never reached. if(STATUS_SUCCESS == status) { KdPrint(("Got event.\r\n")); // Service has answered. Clear the event. Shutdown in progress KeResetEvent(NotifyEvent); } Any Idea ?? Schould I call the OpenEvent() with EVENT_ALL_ACCESS instead of SYNCHRONIZE ?? If I do I got an error that say "Access is denied". How can I create the event with privilege to do this ?? Thomas Tag: How to set WEP Keys programmatically Tag: 27659
