My operating system is 64-bit Windows 10.
Thanks Experts!
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?
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.
