Android Question obtain a value from CallSub

[Roberto P.]

good Morning
how do I get me to return a value from an object with the function CallSub?

For example, an object has a function that returns a string: Sub GetName as string

How do I get me the string to a CallSub? If callsub does not allow it, as I think, there is another way to achieve the same result by having different classes?

Thank You
greetings

In Treeview I do this by a public variable in the class globals (specifically - a list) which the main module fills with data after being caled by callsub.

Not a treeview, but custom controls.
thanks

I found that callsub can also return a value:

dim sField as string

If SubExists(obj, "getField") Then

sField = CallSub(obj, "getField")


end if

Check this out. Or better still copy and paste the code and test it. It should teach you what you need. It calls a sub and returns values.
