This code demonstrates manipulation of the keyboard indicator lights in Windows NT 4.0. A few relevant values were borrowed from the DDK headers, so it is not necessary to have the DDK installed, to build these sources.
There s really nothing fancy about this code, it creates a DOS device for the keyboard device, opens a handle to that device, and calls DeviceIoControl to send IOCTL function codes to the device.
It did require a fair amount digging around in the DDK to create this effect, and it is an interesting twist on an alternate UI mechanism, and thus I felt it might be suitable for inclusion in this archive.
A high-level, multi-threaded function to flash a keyboard light continuously in its own thread, is included. This call is demonstrated in the sample project.
NTKbdLites can be easily built for inclusion in a static link library by defining STATIC_LIBRARY on the compiler command line or in settings.
