That would explain this behavior. I'm learning more about the C Standards. I should always be using that define statement when using any C library function with an "_s" at the end, basically?
Short answer: yes.
About having a local help set this actually is impracticable IMHO, there is so much stuff that would be a very large bulk of storage.
But a simple help of the basic core of WINAPI, the glorious (and no more supported hlp format)
win32.hlp, can be found
here, translated to chm format by Laurence Jackson, thanks a lot for the conversion. You can add this file in the IDE, on menu click
Tools->Customize select tab
Help files, then add the file. It will be searched when pressing F1.
You can also use this
addin of mine. Don't care to build a local Help2 set (even MS abandoned it), but enable the online query search option. Now pressing F1, if no local entry is found, will be issued a query on microsoft online (maybe it needs some updating, but is still working).
