 - Notification Window In a Dll I've been posting questions relate to this for a few days now. Yesterday I was criticized for not providing enough information. I always have mixed feelings about posting too much information, because I believe many will tire of reading, and move on. But, I'll give this a try. I've created a Window in a Dll to respond to PnP events from my USB device. I've double-checked the driver, and it seems to be registering and enabling the interface correctly. I suspect that it's my user mode code that's at fault. Below is my code for creating the window, where the UCan2NotificationWindowProc (not a class member by the way) is of the form: LRESULT CALLBACK UCan2NotificationWindowProc( HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam) {} Can someone spot a problem that might prohibit it from receiving notifications? Thanks in advance, Dennis // Module-level variables HWND hNotificationWindow = NULL; LPCTSTR NotificationClassName = "CUCan2NotificationWnd"; LPCTSTR NotificationWindowName = "UCan2 Notification Window"; ATOM NotificationClassAtom = 0; HDEVNOTIFY hDeviceNotification = NULL; extern HINSTANCE hUCan2ApiInstance; // (Note: hUCan2ApiInstance is determined in a call to AfxGetInstanceHandle() in the InitInstance member function of the // class that the Visual Studio New Project Wizard created.) DWORD CreateNotificationWindow( GUID InterfaceClassGuid ){ WNDCLASSEX WC; WC.cbSize = sizeof(WNDCLASSEX); WC.style = 0; WC.lpfnWndProc = UCan2NotificationWindowProc; WC.cbClsExtra = 0; WC.cbWndExtra = 0; WC.hInstance = hUCan2ApiInstance; WC.hIcon = NULL; WC.hCursor = NULL; WC.hbrBackground = NULL; WC.lpszMenuName = NULL; WC.lpszClassName = NotificationClassName; WC.hIconSm = NULL; NotificationClassAtom = RegisterClassEx( &WC ); if( !NotificationClassAtom ) return GetLastError(); hNotificationWindow = CreateWindowEx( 0, // dwExStyle NotificationClassName, NotificationWindowName, 0, // dwStyle 0, // X 0, // Y 0, // Width 0, // Height NULL, // hWndParent NULL, // hMenu NULL, NULL // lpParam ); DEV_BROADCAST_DEVICEINTERFACE filter; ZeroMemory( &filter, sizeof(filter) ); filter.dbcc_size = sizeof(filter); filter.dbcc_devicetype = DBT_DEVTYP_DEVICEINTERFACE; filter.dbcc_classguid = InterfaceClassGuid; hDeviceNotification = RegisterDeviceNotification( hNotificationWindow, &filter, DEVICE_NOTIFY_WINDOW_HANDLE ); DWORD dwError = ERROR_SUCCESS; if(!hDeviceNotification) { dwError = GetLastError(); DestroyWindow( hNotificationWindow ); UnregisterClass( NotificationClassName, NULL ); } return dwError; } Tag: What is the difference between a network provider and a network redirector?

 - PnP Signed Driver Problem - Serial Device I originally posted a message out here regarding this issue and had some great feedback. To summarize, we mfg a serial device that someone in marketing wanted to make PnP. Since we did not require any drivers, we were able to create an INF file and everything worked â?? UNTIL Microsoft implemented the signing. Now, even though the INF is in the INF folder, the end-user is being queried to add the hardware. We want that to go away. Someone out here recommended that we go through the process of getting a signature; we obtained a signed test driver from Microsoft, yet we are still getting the same results. I have attached the updated INF file as well as the original thread. Any ideas what is going on here? Thank you in advance for any help regarding this issue.

It's the test signature that we can't let out of our internal development systems under penalty of death. After RISâ??ing, with the DL not connected, I copied the INF to the INF folder and installed the MS signature per instructions below: ---- To prepare a system currently running a Microsoft Windows operating system for using test-signed drivers 1. Double-click the test root certificate file (Testroot.cer), and then click Install Certificate to add it to the system. 2. Click Place all certificates in the following store, and then click Browse. 3. Select the Show physical stores check box, and then expand Trusted Root Certification Authorities. 4. Select the Local Computer folder, and then click OK. 5. Complete the Certificate Import wizard and accept all defaults to install the certificate. After you complete this procedure, you can then install the driver with the Add New Hardware Wizard or by using Device Manager. ---- Instead of using the Add New Hardware Wizard, I simply shut down the PC, connected the DL, and rebooted. The Found New Hardware Wizard comes up as before. -------------------------------- ORIGINAL THREAD I have a VERY strange situation I need to solve. We mfg a serial hardware device for downloading data out of a reader. The downloader contains PnP code; when you place the device on the serial port, reboot or run the add device wizard, everything works fine. However, this PnP device does NOT require a driver, so we wrote the below INF file which seems to work fine. There is one catch I would like to solve, and perhaps someone knows how to do this. When we install the INF in the INF folder, we would expect the process to NOT query the end-user. This is NOT the case; the process is querying the user in all cases. Why is that? Is there something we need in our INF, or is it because we do not have a signed driver that is required? We would really like to avoid having the user have to constantly browse to the INF when it is already local to their PC. Any help would be most appreciated. Thanks!

It's worth pointing out that these two errors are not necessarily bad (the second one, especially, is just ChkInf being excessively picky). As far as I can tell, the first error is unavoidable until your driver is WHQL certified. If you are still in development or for whatever reason aren't planning to certify (maybe because it's an internal tool), you can't do anything about that. It seems to me that the second error isn't even an error; the DDK specifically says that you can create a new class if your device doesn't fit into one of the pre-defined classes. If I'm misinterpreting the DDK (see help\install.chm, Device Installation>>Reference>>INF File Sections and Directives>>INF Version Section, the Class and CatalogFile entries) on either point, I'd like to know more about why. -Scot Tag: What is the difference between a network provider and a network redirector?

 - pnp... timeout? Hello, I am trying to install all the device drivers via winbom (sysprep in factory mode) but for some reasons it takes so @#$%-ing long time. My OS is WinXP SP2. First, I see several activities on the system's hard disk but then... it just stays idle (hard disk LED doesn't blink at all). It stays in this mode for a while. Then it boots up to Windows, and sysprep "still" waits for PnP to finish. This also takes some time. My best guess is PnP is timed out because there're still some bangs in the device manager and when I reboot the system, PnP runs again and fixes those bangs. Does anyone know what could cause and how to solve this issue? Please advice, thanks! -P Tag: What is the difference between a network provider and a network redirector? Tag: 55897

 - Filter hook Thanks ahead of time for all that reply. We use a Filter hook by implementing the function PacketFilterExtensionPtr. We currently intercept ipv4. We are looking at adding support for ipv6. I see in the documentation that the first parameter passed to the callback function is the PacketHeader defined as IPHeader. This IPHeader is specific to ipv4. Will this filter hook allow us to see v6 packets? If so, does it pass a different structure if the packet is v6?

 - retrieving the physical location of a volume on one or more disks Hi, The IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS retrieves the physical location of a specified volume on one or more disks. However, this control code is not supported on win2k, which is a platform I must support. Does anyone know a method for retrieving this information that will work on win2k? In an unrelated discussion I noticed someone mentioned that this control code will not work for USB devices, it works fine for me though. The only reason I can think of that this would not work on USB devices is that the PDO for Removable Storage is disk.sys and since disk.sys is not a Volume Manager (like ftdisk.sys, for example), it might not support this control code. But as I mentioned, it seems that the control code works for all types of disks, even if they are Removal Storage and/or USB. Was the statement in the discussion I read wrong or am I missing something? Thanks, Shahar Tag: What is the difference between a network provider and a network redirector? Tag: 55884

 - NDIS intermediate driver & Cisco VPN client problem on XP SP1 Hi Our company is currently developing an NDIS intermediate driver called Sesam that implements client part of Mobile IP protocol. Sesam works in two states - enabled and disabled. In disabled mode it behaves as pass-through intermediate driver. It passes all packets unchanged as if it would not be in TCPIP stack. Sesam is supposed to be compatible with Cisco VPN Client in a way that Cisco VPN tunnel is inner tunnel inside of Sesam Mobile IP tunnel. We have successfuly tested compatibility of our product with Cisco VPN Client on Windows 2000 and Windows XP SP2. It worked with Sesam either enabled or disabled. Our driver binds directly below Deterministic Network Enhancer (DNE) driver. This DNE driver is used by Cisco VPN Client for IPSec tunneling. When we analyzed packets that come through our driver from DNE when VPN was establishing VPN connection. All packets were on ports 500 or 4500 and everything worked as it was supposed. However we encountered severe problems on Windows XP SP1 when connecting using dialup connection (GPRS or UMTS) and our Sesam driver was disabled. On this platform we received only packets on strange ports and each next packet had this port incremented by 1. Eg 1395, 1396, 1397 etc. It is very strange because on Windows XP SP2 we receive normal packets on ports 500 or 4500. We believe that this problem is caused by a change in NDIS handling of loopback packets as described in: http://support.microsoft.com/default.aspx?scid=kb;[LN];813542 This hypothesis is also supported by by a fact that in SP2 it works flawlessly and among SP2 bug fixes at http://support.microsoft.com/?kbid=838207 we have found this one: "Update to permit the Cisco VPN Client program to work in TCP transport mode in Windows XP SP2 After you install a pre-release version of Windows XP SP2, if you configure Cisco VPN Client version 4.0.3.D to use Internet Protocol security (IPSec) over TCP, you receive the following error message when you try to connect to a Cisco VPN concentrator: Secure VPN Connection terminated locally by the Client. Reason 414: Failed to establish a TCP connection. This problem occurs because the TCP/IP protocol is changed to drop any packets that are directed to the loopback IP address, but that arrive on an interface other than the loopback interface. Because the Cisco VPN client sends packets to the loopback IP address, but the packet comes from a physical interface, the packets are dropped. " Since we need our driver to be compatible with Cisco VPN Client on XP SP1, we would like to know exactly how did handling of loopback packets change in XP, how it was fixed in SP2 and whether there is some workaround of this on SP1.

 - DrvEnablePDEV -> DEVMODEW? Hi My driver needs some extra Data in the DEVMODEW (dmDriverExtra) ... now, in the DrvEnablePDEV you get such a DEVMODEW object... can it be guaranteed, that this is a valid structure or could this be a DEVMODEW that someone set while opening the driver? Does Windows first call some other functions like DrvConvertDEVMODE ?? thanks MR Tag: What is the difference between a network provider and a network redirector? Tag: 55868

 - Debugging PnP Notification I'm trying to get PnP notifications to a Window to work. I created a special window for this purpose in my user mode dll. I register for notifications from the particular device interface guid. I see that my WindowProc gets called for general WM_ messages, but so far, I don't see my device PnP messages. On the driver side, I register my device interface in AddDevice. How can I debug this? I can't even tell whether the problem is on the driver or uses-code side. Is there a way to validate that the messages are actually being sent? Thanks in advance, Dennis Tag: What is the difference between a network provider and a network redirector? Tag: 55864

 - CDC Virtual Serial Com Port doesn't pnp on USB. We have a working CDC device that used default windows and linux cdc drivers to form a logical virtual serial port. All we use is an inf file and the device works and we can open hyperterminal(HT) and talk to the device. If we unplug the device and HT is still running and we don't close the port the USB device enumerates as another comport. So HT must close the port previously used and restart, then we have to plug the device out again o have it reenumerate as the com port it was before. Now HT can open the port again. We have another serialtousb adapter that needs a driver. If open the port with HT and (un)plug the device the port stays open and when I connect it again HT still works on the same port. Our device needs to stay on the same comm port even when the application still has it openend. But the CDC driver seems not to support that. Can anyone shed some light in this matter? Do I need to build my own driver, and if I do what to do to have it keep the same port connecting to the application again. (picture the cashier dropping the scanner and having to reboot the whole register because the usb connection was lost for a while. Can't have that..)

 - HELP: Windows Media Center has a driver install bug? Hi, guys: It seems that Windows XP Media Center Version 2002 has a bug. 1>. SYMPTOM Our software needs install two virtual null modem in the windows system. The driver and the driver installer run very well in Windows 2000 and Windows XP professional/Home version, but the driver installer stop responsing when installing these 2 modems in Windows XP Media Center Edition Version 2002(Service Pack 2). The program cannot return when calling <UpdateDriverForPlugAndPlayDevices>.. 2>. BACKGROUND These modems will be attached to another virtual serial port driver. 3>. PROOF I use softice and other windows Log to get the following conclusion: 1. Setupapi.log said the two modems installed successfully. 2.

 - library / changer driver I have developed a mini-changer driver for a new changer with some special characteristics. I am not sure if this is the right place to ask, but I was wondering what products are out there that use the RSM functions or changer API's. I'd like to evaluate such products to both validate the changer driver code as well as understand what products might be suitable for VAR and aftermarket purposes.

 - what is the correct way to remove warnig of digital signing for our deveoping driver ? Dear All Someone made our company's virtual driver of smart card reader h/w with usb interface. But, I want to know the difference between "windows logo program" and "digital signing". If We get a "windows logo program" of h/w and driver, Can we also get "digital signing" of our driver ? otherwise, Is there a method to get only "digital signing" of our driver to remove waring of unsigned driver during installation process. what is the correct way to remove warnig of digital signing for our deveoping driver ?

 - verify no bangs and installed drivers Hi, I set my DevicePath registry value to "C:\MyDrivers\Video;C:\MyDrivers\NIC;C:\MyDrivers\Mouse; [...]; %SystemRoot%\INF" and have Windows XP SP2 PnP installed the drivers according to this path. And now, I would like to know write C++ code to check for the bangs (exclamation sign) in the device manager. If no bangs, then for each device, I also would like to verify if the installed driver for that particular device is the right one. For example is the mouse. I want PnP to install my specific mouse driver instead of native Windows mouse driver (PS/2 compatible mouse). Has anyone done this before? What API should I use? Please advice, thanks! -P Tag: What is the difference between a network provider and a network redirector? Tag: 55832

 - NDIS-WDM driver receives concatenated packets Hi, I am working on a NDIS-WDM driver for a network card that connects to the PC via USB 2.0. One odd problem I see is that the received packets are sometimes concatenated. Sometimes the NDIS driver gets one large packet instead of multiple smaller packets. Another related problem is that the last packet in this large packet is not always complete - part of the packet may arrive as an individual packet or as the first part of the next 'jumbo' packet. My guess is that this is because the device is not using the correct device (and interface) descriptor and so the USB drivers are not treating it as a network device. Does anyone have an example descriptor for a USB network device that I can use? Or am I barking up the wrong tree and the problem is something else entirely? Thanks, - Harshal Tag: What is the difference between a network provider and a network redirector? Tag: 55817

 - memory allocation fails My PC 1394 driver allocates memory when it receives packet. For my testing, I am allocating memory (each allocation 2k bytes). Memory allocation fails after 100 MB. My PC has 1 GB RAM and task manager shows atleast 750 MB physical memory free. I dont understand why memory allocation fails nearly at 90MB. I dont think memory is so fragmented that I cannot get more than 90 MB out of 750 MB. My release version will limit use to max 32 MB. I dont understand why it fails at nearly 90MB during testing. This is non-paged memory allocation. I know non-paged pool is limited, but I see it is still available in task manager when my memory allocation fails. Does Windows internally take care not to allocate more than certain quota to a particular driver. Just curious to know. Thanks.

 - Device driver under XP 64 I am migrating a 32-bit device driver to a 64-bit world. My platform is 64-bit hardware + XP 64 (downloaded). I cannot install my 64-bit driver with the INF files (designed for a working 32-bit driver). "Digitally not signed" stuff keeps popping up during the installation. Does the XP 64 refuse to install the unsigned drivers? Or, do I have other problems? Tag: What is the difference between a network provider and a network redirector? Tag: 55813

 - TDI problems Hello, I am trying to write a TDI device driver filter. I receive the IRP_MJ_INTERNAL_DEVICE_CONTROL with a minor function of TDI_SET_EVENT_HANDLER, with the EventType being TDI_EVENT_CONNECT. So I then save the 'current' event handler pointer and context to be used later. And ultimately, MY CONNECTED Event Handler does get called when connected. Now what I do is I CALL the 'original' event handler using the event handler pointer and context I saved previously as aforementioned and it looks like the AcceptIrp and ConnectionContext is built. Is this TRUE? Can I simply call the 'original' handler? But according to TDIMon(sysinternals), I see the TDI_ACCEPT request being created but it is timing out, and my receiver client never know's he's actually connected. Does the original event connected handler properly build the AcceptIrp? Obviously, there is more I need to do here. How do I make my driver not 'time out' on the TDI_ACCEPT request? Is there any 'good' source code to look at? /Loren Tag: What is the difference between a network provider and a network redirector? Tag: 55810

 - USB composite device - keyboard, mouse, RNDIS I am attempting to write the firmware for a USB device that will be a USB HID keyboard, a USB HID mouse, and a USB Remote NDIS device all at once. Although a typical composite device sets the DeviceClass member of the device descriptor to 00h, I think this will result in a separate driver being loaded for each interface. The RNDIS portion requires a single driver for its two interfaces (Communications Class & Data Class). Can I set the DeviceClass member to 02h (Communication Device Class) and have the mouse driver load for the first HID interface, the keyboard driver load for the second HID interface, and the RNDIS driver load for the Communication & Data interfaces?

 - Print Processor -- Convert SPL file to EMF I've seen example source code to read an SPL file and extract the EMF files inside, but I've also read that this isn't a very robust method. I started looking into the API functions like "GdiGetSpoolFileHandle" which appears to be a more robust method. Has anyone used these functions to write out EMF files instead of printing to a printer? A "virtual print driver" if you will, or "virtual printer". Can anyone tell me the series of function calls I should make in order to do this? I can figure out the details, I imagine, if I know where to start. The only functions I see are to play the EMF file for each page, which will end up playing to the "printer". In my case I don't have an actual printer, so I want to play the EMF file to another EMF file. With the normal API functions to work with EMF files this would be easy, but I'm thinking the print spooler API doesn't include the functions I need. Anyone have experience with this? I guess I could stick with the methods I've seen that read directly from the SPL file and extract the EMF files from inside, but don't the EMF files use a little different format sometimes, and can't the location of the SPL file be hard to get? p.s. - I need to support Win98/ME, as well as NT4/2K/XP.

 - Nvidia Display Driver, Ntoskrnl forwarded dependancy question in Win2K Hi: I've been trying to sort out a Kmode_Exception_Not_Handled BSOD on a machine that has always been stable until DirectX 9.0c was installed to replace 8.1. Error happens as soon as Direct3D is invoked and is repeatable. It has an Nvidia PCI GeForce4 440 video card, K6-III 256MB. W2K Pro SP4 I looked at the dependencies of nv4_disp.dll, the main device driver file, and using depends.exe and I see that there is a missing forwarded module - NTOSKRNL.DLL. This file does not exist in W2K. The correct name is ntoskrnl.EXE. nv4_disp.dll forwards to ntoskrnl.dll through Win32K.sys. It also, correctly, forwards to ntoskrnl.exe so both the .dll and the .exe are shown as dependent. The missing functions are: RtlRaiseException RtlUnicodeToMultiByteN RtlUnwind ProbeForWrite DbgBreakPoint These are actually present in ntoskrnl.exe. This looks suspiciously like the driver writer has mistakenly used a LoadLibrary function to the .DLL name when it should be using the .EXE name. Can someone give me some pointers on how the device driver specifies that ntoskrnl.exe should be invoked? Is it just a matter of explcitly using the .exe path in a LoadLibrary call. I dumped nv4_disp.dll but the strings table seems to only show "ntoskrnl", without any extension. Therefore I can't patch the file. Am I right about this? Surely dependencies should be resolved correctly in drivers. A lot of people (judging by Google search) are having these kind of problems. Is it just a matter of not catching an exception? In this case the Kmode is 0xC000001D (illegal instruction) in nv4_disp.dll Thx to all Tag: What is the difference between a network provider and a network redirector? Tag: 55760

 - Connect and Disconnect Callbacks I've posted a question similar to this before, but I'm going to try it again. I'd like to notify my user mode code, running in a dll, when one of my USB devices is connected or disconnected. Note that the User code may have been started before any devices were connected, or after one or more have been connected. I see an API function where my user mode code can register for notifications to a Window or a Service, but I don't have a window, and adding a service seems to be adding undue complexity (especially when I've never worked with them). Can someone suggest a way to do this? Thanks in advance, Dennis Tag: What is the difference between a network provider and a network redirector? Tag: 55755

 - DRIVER_POWER_STATE_FAILURE in Windows 2000 Problem. Hello All, We have a Encryption/Decryption Upper class Filter Driver which works well for Windows 2000 and Windows XP. But Sometimes in Windows 2000 during shutdown it causes DRIVER_POWER_STATE_FAILURE Bugcheck. This happens only in "some" windows 2000 systems. In the same system some times during Shutdown the screen goes blank with a blinking cursor at the top. All these problems occur only in Windows 2000 and NOT on Windows XP. Is there a specific reason for the same? I know its a power tranisition problem But how to proceed after that. Thanks Very much. Regards Shal.

 - Out of memory... Hi folks, i've noticed a few systems that have the whole memory between 0xA0000 and 0xFFFFFFFF allocated by various hardware components. This causes the initialization function of my driver to fail, because it requires a 4k memory window. Now i would like to know what's the ususal way to solve a memory shortage? Here's what i've tried so far: Installing the most recent drivers did'nt helped. Most of the memory below the first MB is consumed by a component called 'System board', which can be deactivated through the device manager. But even if it is deactivated it still claims all the available memory between 0xA0000 and 0xFFFFF. (Kinda strange, isnt it?) So whats the best way to ensure a 4k memory area is available for a driver? I would appreciate any advice. Thanks in advance, Mike Tag: What is the difference between a network provider and a network redirector? Tag: 55751

Hello,

is the network redirector just the filesystem driver itself? And a
network provider includes the network redirector and a network provider
library?

I'am a bit confused...

Thank for your efforts!

Yes.

> network provider includes the network redirector and a network provider

No. Network provider is a DLL registered for user-mode use by things like
Windows shell (Network Neiboughrhood window and Map Network Drive toolbar
button) and NET.EXE command.
