Delphi App network activity

If the forms are removed or encrypted they cant be viewed in resources. For example, in my applications you cant see the forms on the resources because they are encrypted with Citadel. On the other hand, the UDP component may be created dynamically without a component on the form

Anyway INDY doesnt use any system DLL to accomplish the udp sending, means has no exports. The only way to see how things work, is to create an empty app, an empty form and an empty form/app with a UDP sending function on it and compare. Maybe that will help you studying.

I can generate those 2 exe for you, both for Indy9 and Indy10. Just let me know.
