Hi!
First, check the actual exported name from DLL. It may be decorated and
looking like "_squareIt@8". You can use "depends.exe" from Visual Studio tools.
Second, exported names are case-sensitive.
Next, make sure that declared types of parameters and return value are valid
and parameters passed "ByVal". Exported functions in Dll are differs not only
by name, but also by number and types of parameters.
