I am trying to import a DLL that was created by me under the VC++.

FASM compiled for me without errors.
However when I run the exe. It keeps giving the error,

The procedure entry point cound not be located in the dynamic link library.

Is there a specification to write dll under C++,
so that FASM will recognize my dll entry point?

Typo in function name Smile

PS: use some tool to inspect PE exports and imports.

Use
Code:
extern "C" __declspec(dllexport) foo    

to declare foo and use cinvoke to call foo.

P.S. Sorry, didn't notice, that you have a 64-bit output. In this case cinvoke is not necessary.
