Hi, I wrote an app under vb.net to calculate huge data from MS Sql server.
Whenever this app is running, I could not do other work. Or else, the app
will become "not responding" but actually it is still running and
processing. Also, the progressbar will no longer active.

How should I overcome this?

TIA
 
just run it as a thread or asynch call..

a quick fix to the issue...call it on a separae thread like the following..
just note that doing it this way when u call LongCalc u cant include
parameters..
if u need to send some over u can put longCalc in a class and set some
properties or variables for it to read from.


Private Button1_Click( .....)
dim th as New System.Threading.Thread(LongCalc)
th.Start
End Sub

sub LongCalc()
'code here ...
End sub

Actually

dim th as New System.Threading.Thread(AddressOf LongCalc)
