visual studio 2008 - concentration closes unhandled difference occurs

i have problem an unhandeld difference occurs while debugging winform vb.net project.

the problem concentration terminates i have start concentration again, instead retrying movement box vs2003

the unhandeld difference implemented new my.myapplication category found applicationevents.vb

private servant myapplication_unhandledexception(byval sender object, byval e microsoft.visualbasic.applicationservices.unhandledexceptioneventargs) handles me.unhandledexception
    low handler new globalerrorhandler()
    handler.handleerror(e.exception)

    e.exitapplication = false
end sub

note: handler.handleerror only shows dialog box logs blunder record file.

i also attempted following formula used work vs2003 nonetheless law same intrepidity run vs2008:

    addhandler system.windows.forms.application.threadexception, addressof onapplicationerrorhandler
    addhandler appdomain.currentdomain.unhandledexception, addressof onunhandledexceptionhandler

onapplicationerrorhandler onunhandledexceptionhandler does same handle.handleerror

running concentration outmost vs2008 law approaching intrepidity (the concentration doesn't terminate) nonetheless augmenting the exam cycle during debugging.

update: i have total illustration formula answer denote problem c#
