wdk

I am trying to define a double data type variable in a C code which is going to be used in the Windows kernel. The code compiles but gives error while linking. I tried using libcntpr.lib in the source file and also defining __fltused variable in the code but to no avail. I'll really appreciate if someone can help me on how to use this. Don't know if still applicable to current WDK but Walter Oney demotivates the use of floating point stuff in drivers here . The problem is worse than just finding the right library, unfortunately. The C compiler's floating point support assumes that it will be

Can someone see if I am doing this right please: //DeviceManager.h #include <windows.h> //#include <hidsdi.h> #include <setupapi.h> #include <iostream> #include <cfgmgr32.h> #include <tchar.h> #include <devpkey.h> extern "C"{ #include <hidsdi.h> } //#pragma comment (lib, "setupapi.lib") class DeviceManager { public: DeviceManager(); ~DeviceManager(); void ListAllDevices(); void GetDevice(std::string vid, std::string pid); HANDLE PSMove; byte reportBuffer; private: HDEVINFO deviceInfoSet; //A list of all the devices SP_DEVINFO_DATA deviceInfoData; //A device from deviceInfoSet SP_DEVICE

I am using the Windows Driver Kit (WinDDK 6001.18001) to build my userspace application rather than Visual Studio 2005. I am taking this approach because we also have to build driver components, so I'd prefer to have a single build environment to build everything. Microsoft itself uses this approach for several products. This was working fine until I started using Boost 1.38.0. I'm not using C++ in the kernel mode components, just the userspace applications. In C++ code, it's natural to use the boost libraries. Unfortunately, the WDK doesn't agree. The first error I noticed is that "#include

How does one begin writing drivers for Windows? Is there some sort of official DDK "Hello World" example out there? While I'm sure it will be way above my head at first, eventually I would like to create a simple MIDI driver, much like the Maple Virtual MIDI Cable where the MIDI messages come from a user application rather than a physical device. (The trouble with using the off-the-shelf MIDI loopback drivers is that the existence of an input and output end is often confusing for the user. My application generates MIDI output that gets sent to the MIDI input of other programs, so if I could

On Windows (XP-7), is there a reliable way of programatically differentiating between USB floppy drives and USB flash drives in C++? At the moment, I'm using WMI to get updates when new Win32_LogicalDisk instances are detected, and then using the DriveType attribute of the LogicalDisk object to figure out a basic type. This works quite well, except that floppy drives and USB flash drives are both of DriveType DRIVE_REMOVABLE , so to differentiate between those (floppy vs. flash), I'm using the IOCTL_STORAGE_GET_HOTPLUG_INFO interface to figure out if the device is hotpluggable, and was working
