Please read http://msdn.microsoft.com/en-us/library/ms682586%28VS.85%29.aspx

You have two ways:
-providing the full path to the DLL to LoadLibrary
-put the library in the DLL search path. The easiest way would be to
put it in the same folder as the executable.

It is named SafeDllSearchMode. Basically, it changes the directory lookup order.
