Question

Answer 1

+2 A:

Dim doc As XDocument = XDocument.Parse(str)

This gets me the XML string into an XML object. I still can't call the function... It's a start though.

Answer 2

+2 A:

What function are you talking about calling? "Value"? That's not a function. It's a property.

Dim val As Object = doc.Attribute("name").Value

And how can I call the function whose name is stored in val?

Moshe 2010-03-03 13:48:30

@Moshe: you never said you have the name of a function stored in the XML. I have no idea how to call a function whose name is stored in a string, I only know it's usually a bad idea to play such games.

See edits. Thanks though. +1

@Moshe: if there are a limited number of possible functions, then just use a switch statement. I strongly suggest you not try to get fancy with doing dynamic function calls through reflection or something. That can be very difficult to maintain.

John Saunders 2010-03-04 00:49:23

@John - I would have to disagree on both counts. Dynamic function calls are easier than a switch statement to maintain because I won't forget to add cases. Also, there are an unknown number of functions at this point. Thanks.

Moshe 2010-03-04 03:53:45

@Moshe: dynamic function calls are tougher to maintain because they need to be maintained by someone who uderstands dynamic function calls. A far larger number of developers know what a switch statement is.

John Saunders 2010-03-04 05:19:10

@John - ah. I didn't understand you before in regards to mauntaining it. This happens to be a (proprietary) program fo r myself. The idea is that I won't need to rely on swf studio or flash jester to make Flash access system functions like a regular desktop app. I don't know what functions exactly I need except that they are likely to change, hence dynamic function calls.

Moshe 2010-03-04 14:22:48

@Moshe: good luck. In most shops, not everyone knows Reflection. In yours, everyone already does.

John Saunders 2010-03-04 14:36:23

@ John - Reflection? Is that the term for dynamic functions? Cool, you live and learn. Thanks for your time.
