Using AutoIt3 Library calls in VC++ project (WIN32 application)

[Kanit]

I am trying to use AutoIt library calls like AUTOIT_Send/Send in my visual C++ project, but I am getting error like AUOTOIT_Send identifier not identified/ Send identifier not identified.

Info : I have included AutoItX3.dll to my project run path, I have included AutoItX3.lib to my project link libraries path and I also have DLL path included in my VC++ project (its a WIN32 application)

Can any one tell me How can I resolve this problem?
