Hello,
I couldn't find a DFL subforum so I decided to post here, I
apologize in advance if this isn't the right place.
I'm currently using DFL to write a Youtube downloading program
with a simple GUI. I chose DFL because I enjoy the Entice
Designer WYSIWYG capabilities, but also because I found DFL to be
easy to use after reading the sample codes, especially the
Phonebook example. Unfortunately the project is more or less
abandoned, and the documentation is incomplete.
To make a long story short, there is a ListView that I want to
populate with information that could take a while to retrieve
(video qualities and links), which temporarily freezes the
program. The way I did things thus far was to simply extend the
Thread class and pass it the UI elements and let it modify them
directly once the information is retrieved, or by just running
the task in a delegate that has access to the elements I wish to
modify, then passing said delegate to an instance of the Thread
class. It worked with TextBoxes and Buttons and other elements,
but not with ListView. I did some reading and it turned out this
was a frowned upon method, that the UI should only be modified by
the UI thread, and that this could be achieved with the "Invoke"
method according to some C#-tagged replies on stackoverflow. I
did some more digging and found an Invoke method in the Control
class, but its signature is hard for me to decipher. I also am
not sure how to use this with an onClick event.
Control.invoke documentation :

Any input is appreciated. Thanks in advance.
