View SQL execution plan in vb.net

When I run a query in SQL I can press a button see the execution plan.  How can I run an SQL query from a GUI and see the execution plan?

My problem is that the SQL query runs fine from management studio, but not when run from the GUI.  It could be a case of parameter sniffing as per these links, but I thought the execution plan could confirm this.

My GUI is a vb windows form GUI and links to a SQL 2005 database.  I'd like to be able to do this with a web based GUI too.

Use the Profiler, with this you can choose to save the executionplan in the trace. Filter on your application if its a Heavy used server.

You don't
you start profiler (hook up against the SQL Server your GUI is targeting), use the normal template (Standard), modify under:
Events Selection, check Show all events
  Navigate to Performance
    Check Showplan XML
Run the trace

Now run your GUI thing
Check the trace
After analyzing the queryplan, Fix/index/query/Stored Proc/statistics or just some error

Repeat by restarting the trace, run query in GUI again until problem is fixed.
Done!

to start the profiler, start SSMS, use:
  Tools/SQL Server Profiler

And off you go
