wdk

I am trying to modify a ethernet driver using WDK tools provided in Visual Studio 2012. The samples provided in the WDK are 'miniport adapter' and 'NDIS Light Weight Filter' among others. I am still at the very beginning of driver writing and hence finding it tough to navigate through the code. I was able to install the miniport adapter after building it in Visual Studio 2012 [Shows up as 'Microsoft Virtual Miniport Adapter' in my network adapters list.] I am able to assign it a IP address and Subnet mask also.[I found out that this does not connect to any physical device on my PC]. I also

I just started with driver development. For some experiments with loading, unloading and debugging I have written the following simple driver: #include <ntddk.h> void DriverUnload(PDRIVER_OBJECT pDriverObject) { UNREFERENCED_PARAMETER(pDriverObject); DbgPrint("Driver unloading\n"); } NTSTATUS DriverEntry( PDRIVER_OBJECT DriverObject, PUNICODE_STRING RegistryPath) { UNREFERENCED_PARAMETER(DriverObject); UNREFERENCED_PARAMETER(RegistryPath); DriverObject->DriverUnload = DriverUnload; DbgPrint("Hello, World\n"); return STATUS_SUCCESS; } I compiled the driver for my target system, Windows 7 64bit,

I am developing a KMDF virtual mouse driver. The general idea is a KMDF root enumerated non-filter driver which will be able to send output reports to the mouse and keyboard driver stacks. My driver is already working and sending requests to other driver stacks, but with no result. Report types and packet formats are pretty undocumented on Microsoft resources. There are no information about which data and to which device I need to send in order to move the mouse pointer, simulate clicks (with either mouse or keyboard). There is only general information about HID clients, drivers etc. Their

Is there a way to obtain PCI coordinates (bus/slot/function numbers) of devices by using Windows c/c++ API (e.g PnP Configuration Manager API)? I already know how to do it in kernel mode, I need an user-mode solution. My target system is Windows XP-32 bit. I've eventually found a simple solution (it was just a matter of digging into MSDN). This minimal code finds the device's PCI coordinates in terms of bus/slot/function: DWORD bus, addr, slot, func; HDEVINFO h; // Obtained by SetupDiGetClassDevs SP_DEVINFO_DATA d; // Filled by SetupDiGetDeviceInterfaceDetail SetupDiGetDeviceRegistryProperty(h

Can't find it in Windows SDK and DDK, but some of our existing code includes it. The only meaningful link I found by Google is: http://msdn.microsoft.com/en-us/library/windows/hardware/hh450839%28v=vs.85%29.aspx What's it? This is a new header file, currently only present in the SDK/DDK of Windows 8 Consumer Preview / Visual Studio 11 Beta. I think this header is for splitting the Win32 API into Desktop/MetroApp 'partitions'. For reference, the winapifamily.h is located at C:\Program Files (x86)\Windows Kits\8.0\Include\shared 来源： https://stackoverflow.com/questions/9509166/what-is

I have an audio device (a USB microphone) and I want to find out what audio formats it supports natively (bit depth & sample rate), on OS X there is a nice kAudioStreamPropertyAvailablePhysicalFormats Core Audio property, but I fail to find something similar on Windows. I know there is this question Windows Core Audio Api get all supported formats on capture device but The answer is bad... and I'm not limited with windows Core Audio APIs, I need any way. Windows itself somehow knows it, so most likely there should be a way, via IOCTL for example, DirectShow or WMI or something else. Probably

I was trying to compile and deploy the WFP sample obtained from MSDN called msnmntr but the same problem applies to all samples. This and all samples fail to deploy because there's one step in the documentation that are missing in Visual Studio 2012 Ultimate. It says: 1) Open the property pages for your driver package. Right-click the driver package project in Solution Explorer and select Properties. 2) In the property pages for the driver package, click Configuration Properties, click Driver Install, and then click Deployment. However there's no such option in the Visual Studio 2012 as you
