Dude, it's really very simple. You have an arraylist, and you search by creating an index to start ( length/2 ), then you keep splitting the index up or down in order to bring down the range you're searching. It's a simple enough problem that I can't give you example code without doing your homework for you. How about you give it a go, and post your code ? If you've tried to do your own homework, and you get stuck, I'll be glad to help.

A very good resource for this type of algorithm is The Bible ... "The Art of Computer Programming", Volume 3 - Sorting and Searching, by Donald Knuth.

The new Visual Basic Express looks like it would be cool to try out. Will it mess up any of my Visual Studio .net 2003 projects, and asp .net 1.1 sites? Thanks
|

I would HIGHLY suggest making copies of them BEFORE you attempt to open them in Express. Opening your current projects in the new 2005 editions of VS.NET will upgrade the projects to the VS.NET 2005 Project formats, making them unusable in VS.NET 2003 and below.

I was only going to open my old projects with Visual Studio .NET 2003. If I didn't open them in the new version, will they still get messed up? I'll make a backup just in case though.

Nope. So long as you don't do anything with them in 2005, there's no problem.

I'm interested in a file-watching VB program. I've downloaded several programs that use FileSystemWatcher. While this is a very handy utility for checking changes to a directory, I would like an event to be raised when a particular file is used(opened or accessed). The file may used be several times during a day.
I'm experimenting with certain File properties like GetLastAccessTime and SetLastAccessTime. A boolean property would be much simpler.
Any ideas as to how to go about this?

What you want can't be done with the FileSystemWatcher. The only way you'll be able to see other processes open files is if you write a kernel mode driver extension to NTFS. This is FAR from trivial, requiring a 5th degree black belt in NTFS internals and driver development.
For a hint of what's involved, search for FileMon at www.sysinternals.com.

Hi All,
I have a VB.Net (not that it matters), managed application component (COM+, Serviced Component) where I need to be able to do some fairly simple initialise/deinitialise stuff at the process startup and shutdown, so it is available for all object instances thereafter and cleaned up after shutdown. My component is managed, and the startup/shutdown subs would be calling some unmanaged functions, but they're extremely simple - they're only method calls to an independent server running on the same machine.
Is there a really simple way of doing this using the normal methods immediately available to me, like through activate/deactivate?
Note, I would really rather not have to do this through the IProcessInitializer interface unless I really have to. I've had IProcessInitializer implemented, but never got to a position where it worked, as well as it being more effort to configure which is disproportionate to the simple thing I want to do.
Thanks a lot in advance,
David

I'm wondering if anyone has seen a control for .NET either C#, VB.Net that is the equivilent of the Listview that instead of providing rows in the Downward direction, provides the concept of a Row Horizontally.
I need to provide a list of things for the user to edit, but I want to provide it across the screen.
If i'm just using the listview incorrectly I'd also like to hear about that.
If anyone has any suggestions I would greatly appreciate it.
Thanks

Do you mean vertical rows? Would the listview's Icon View do the trick for you or do you need to show more data than just an icon and a bit of text?
