Recently, it was finally over. NVIDIA has made the documentation of their driver API accessible to all. That gave me the opportunity now anative gadget without detours via N-Tune to build.
Since 8 September it is now also possible for normal-mortal direct access to the NVAPI get. NVIDIA has the appropriatedocumentation, lib file and header finally released for everyone.Previously this was reserved for OEM customers, or NDA.
Unfortunately, it was for me, who handled mainly with C #, not easily possible to now access the NVAPI. Since NVIDIA just a lib file, plus C + + header makes available a direct access from C # via PInvoke is not possible. It was therefore necessary to create a wrapper library in Managed C + + as this, the lib file is statically linked. Presented to me as an absolute C + +, so even lay a real challenge, it was also necessary to include this then, suitable for each platform (x86 / x64) compile to.
Because in my C + + knowledge, as already mentioned, in fact do not exist, I was unfortunately not possible to prepare them directly for access by gadgets. I have therefore decided then to another wrapper library in C # to build.
Fact that I am now but for each platform in each case had to have a library of wrapper to load the appropriate file to match the platform. A direct reference assembly is not working at this point. . NET framework using reflection, but luckily offers the possibility of so-called "Late Binding". This made it possible for me to determine, first, the platform and then load the appropriate library and made available for the parent gadget.
The result from this gadget is now required, therefore no auxiliary tools, such as N-Tune, Speedfan, etc. more and reads the temperature directly from the NVIDIA driver.
The design this time, I have held up relatively simply and only the most essential, the temperature and the types of graphic type, accommodated. The temperature bar would still accommodate the gadget very cluttered look and can thus fell victim to the cutbacks.
