can i create a dll, what includes other dlls?

I convert an application code to dll file. I use functions from other dlls. In my application code, I have include a header files for the dlls and it works. In the dll file, I included the same header files, but the dll can not be loaded successfully, with a link error LNK2001. how can i set the path for the dll? thx. Lei

It seems your dll needs to a lib file.

Yes. You need to link your Dll project with the .lib files from the Dlls your project calls into. If you don't have .lib files for the dlls you need to use then you'll have to load them at runtime using the
LoadLibraryAPI function and useGetProcAddressto get function pointers to the entry points for the functions you want to call. If all this seesm a bit arcane then at least you now know why COM got invented. :)Nothing is exactly what it seems but everything with seems can be unpicked.

If you do not want to use "loadlibrary" see other reply) 1) You cannot set a path for a DLL, you must either have your new DLL in the same directory as the DLL you are calling, or put it in the windows/system32 directory. 2) You need to link the lib file. Either add the lib file using project properties or add following to your source file #pragma comment(lib,"DllName.lib") 3) Add the header file for the DLL to your source file.
