ok in vb6 i would use this to check all items in a listview.
[Code]...
Now Here's my confusion. And i spotted at least one other person on here who was asking the same thing about this.But got no real clear answer that i could see. as a test to compare i tried his suggestion and loaded the same listview up in both a vb6 app and a vb.net app..The list i used was quit large so the comparison would be very through..my list was in the 80,000 lines range tho..yeah talk about overkill The vb6 app checked/unchecked the items within a matter of milliseconds..the vb.net took an extremely long time tho..well not extreme but was very noticeably slower about doing the loops.

I've run into a bit of an issue. Sometimes a user starts a search, but doesn't want to wait for the search to finish because they thought of some change they want to make or because the search is taking too long.
How would I cancel a Search? I understand that I would have to run the Search on a separate Thread. Would I just abort the Thread? Or do I need to send SQL Server something to let it know that it can cancel the query?

I have a window which has 8 items in a listview along with 2 radio buttons below the listview. The user is able to select one or more selections in the listview and turn the selection on or off with the radio buttons(live, prior to hitting the submit button), my question is how do I tell which selection was changed? I was going to put the one or more selections into a string/array and use that later for some messages once the user hits the submit button. I can almost think of it but can't quite get there, i'll be using an if/else with the .selected option in listview items but am not sure how to tell if the user, say,goes back and changes the option from On to Off(Off originally)to remove that option from the array.
