I want to store IP number in a column in db but which column type should I use? Of course I can use string but isn't this a waste of storage space? Can I not store IP nr in another type in db that saves space?

Any one know any open source user control that is similar to gridtreeview. Basically, I want to show a multi column treeview that when expanded, user can edit certain column values. The columns can have a text box or dropdown etc.
I use this query for my table but it retrives the value for each row. It does not retrieve the size of the column name. I need to know the number of characters occupied in particular column. How do i get this value?
what I need to know is how to show a count of how many users are signed on with a custom sql script, here is what i got that shows total users but not total online
[Code]....
Again this gives a total count but i need a total count of who is online with this setting, and try to keep it in sql statement if possible as i have not yet learned how to use stored procedures.
