Why do I need to use LoadLibrary in MSDN?
Not only does this work around the dot defect, it prevents a security vulnerability. Highjacking the current directory for your application can cause your app to run arbitrary code. See MSDN on LoadLibraryEx for a better understanding of the complexities of using LoadLibrary.
