I'm getting these two errors, like a 100 of them, but I'm sure it's from the same cause. I searched the web and it said to add stdio.h header, didn't work. I also tried to add winbase.h that also didn't work. Any suggestions? Thanks.

Solution 1

If you look at the documentation[^] it will tell what header file you need to include, and what library you should link with.

Thanks; and I'm a slow typist.

Since I'm a beginner, would you be kind enough to tell me where the kernel32.lib and the kernel32.dll are placed in the properties of my project.

Richard MacCutchan 11-Aug-11 13:17pm

kernel32.lib is a link library definition file that is required by the linker, so should be added to that section of your project. If you are using a version of Visual Studio it is usually one of the defaults. If you are generating your project manually you will need to add it to the correct part of the link options.
kernel32.dll is the dynamic link library that contains the actual functions previously defined by kernel32.lib. The DLL file is loaded at run time by the program loader and, since it is a system library, is stored in Windows\System32 and located automatically.
