How to call DLL into ax 2009

Hi,

If anybody knows how to call dll in ax 2009.pls help me in this.

with call the method of library.

What is in the DLL?

If it’s a .NET assembly, install it to the appropriate bin folder or to GAC, add a reference to AOT and use CLR Interop from X++.

If it contains a COM object, use COM* classes (also see Development Tools > Wizards > COM Class Wrapper Wizard).

If it contains other unmanaged code, use DLL* classes.
