Hi, there, all fellow programmers I need a help on this. I have a code in vb6. It acts when a click action is made on 'X' on form1. Here is the code :-

private sub form1_unload(cancel as integer)
dim confirm as integer

confirm=msgbox("Sure to exit ?",vbyesno+vbquestion,"Confirm Exit")
if confirm=vbyes then
elseif confirm=vbno then
exit sub
end sub

The above code works fine in vb6 environment. Now I need to write similar code in vb.net 2003 also. Does anybody have any idea how to do this? Plz this is urgent. Reply me as soon as possible
