i using asp.net 4.0 , mvc 2.0 web application. project requiremrnt have use server side control in application not possibl in noraml case. ideally want use adrotator control , datalist control. i saw few samples , references in codepleax mvc controllib howwver found less useful. can tell how utilize theese controls in asp.net application along mvc. note: please provide functionalities related adrotator , datalist controls not equivalent functionalities thanks in advace. mvc pages not use normal .net solution makes use of normal .net components impossible. a normal .net page use event driven solution call different methods service side mvc use actions , view completly different way handle things. also, mvc not use viewstate normal .net controlls require. found article discussing mixing of normal .net , mvc.

regex - Constructing a Regular Expression from a Finite Automata -

-

i'm trying construct regular expression finite automaton found self stuck one. regex use this:

? = 0 or 1
* = 0 or more
+= 1 or more
| = or
_ = empty string
@ = empty set
() = parentheses

as understand strings must either "b*" end "a*" or end "a+bb+"
have ((b*(a+(bb))*)*) doesn't take account string ending 'a'.

as said, i'm 100% stuck , can't head around how supposed work this.

image: http://img593.imageshack.us/img593/2563/28438387.jpg

code:
type of automaton
fa

states
q1
q2
q3
q4

alphabet
a
b

initial state
q3

final states
q3
q4

transitions
q1 q2
q1 b q3
q2 q2
q2 b q2
q3 q4
q3 b q3
q4 q4
q4 b q1

any solutions or tips appreciated!

it isn't possible q2 final state. remove , resulting dfa should easier convert.

as understand strings must either "b*" end "a*" or end "a+bb+" have ((b*(a+(bb)))) doesn't take account string ending 'a'.

imagine q3 not final state, , q4 initial state. regex then? changing want shouldn't hard, don't afraid have same state and/or transitions described more 1 part of regex.

one more hint: i'm pretty sure you're going need use either ? or | @ least once.
