if you are loading textfile data into the datatable, you can use compute
method of dataset/datatable I am not sure. check compute method in the msdn
help.

I loaded data that is in .txt file into a datatable. Now I
would like to run a group by query on that datatable, how
can I do that??? If I can't do that, how can I sort and
sum the data that is in .txt file in a easiest way in
vb.net???
