I'm going to develop front-end application connecting to a Progress v9.1c.

The GUI will have complex logic therefore I will not be able to use simple
HTML page
but I will have to develop them in VB or 4GL (I cannot use Java).


Does 4GL language allow to develop complex GUI with components (table, list,
tab panel and tree)
like VB?

Does anyone have experience developing complex GUI with VB and 4GL?
Which are the main differences (about performance, development time, use
facility ) ?

Does anyone have experience using ActiveX to access remote AppServer?
Is it a robust and flexible solution or arises problems or limitations?
 
Yes you can develop complex GUI applications with the 4GL utilising ActiveX technology, and imo it is a much nicer environment to develop in than vb.
