Need more info. What are you trying to do? Is this about the windows OS API? Is this about a particular program?

edit: Is this about email?

Thanks Experts!

It is a data transfer client software.
It implements API data transmission through DLL.
It provides data interface specifications.
It is based on C#
I don't know how to change it to a JSL implementation.

It has more regulations.

I've excerpted some of it.

This is my first experience with this kind of content.So I don't know how to deal with it.

Thanks for the expert's help.

The JMP C# automation examples might help. I think automation might be the keyword you are looking for.
