SeMartens3-Feb-09 3:08 SeMartens 3-Feb-09 3:08  Hi, there is a class called System.IO.FileSystemWatcher. Using this class you can observe file actions on directory or file. If a file is copied the FileSystemWatcher will throw the event OnCreated. Problem is that you don't know if it is a newly created file or a copied file... but maybe it is a good point to start.

The FSW starts to perform badly the more you have it watch. He really doesn't have a solution to use since there is nothing that signals "Hey, there's a copy going on!".

Maybe my question is not quiet clear so I'll explain first what I want to have. So I have one listbox that I populate with a result of a calculation. Let's say the listbox contains 100 items. What I need is to save those list items into a file (maybe I want them later even if I already closed the program for another process). What you showed me is just the way how to write into a file but not how to retrieve all value of the list and save them into a file. This is what I want. But, fortunately, I know now how to save the listbox contents : 1. I count the number of items : listbox1.Items.Count; 2. recursively set each Items selected : listbox1.SetSelected(i, true); and StreamWriter each selected Items directly. for example : int number = listbox1.Items.Count; StreamWriter sw = new StreamWriter(@"C:\list.csv"); for (int i = 0; i < number; i++) { listbox1.SetSelected(i, true); sw.WriteLine(listbox1.SelectedItems[i].ToString()); } sw.Close(); Hope this will help someone else. (of course you can personalize it like adding savefiledialog...)

Re: Disconnect a FTP connection EliottA3-Feb-09 4:16 EliottA 3-Feb-09 4:16  You can send the "close" command to the ftp server to quit the connection, or close the stream AFAIK.

The use of 'var' Nathan Gloyn3-Feb-09 2:15 Nathan Gloyn 3-Feb-09 2:15  Since the var keyword has been introduced for anonymous types I have noticed more and more code examples (and seen in my work) people using var rather than a defined type. To my mind var should only be used when an anonymous type is being used and only then not instead of a defined type. What are peoples thoughts? are you seeing a rise in the use of var? Re: The use of 'var' J4amieC3-Feb-09 2:24 J4amieC 3-Feb-09 2:24  If you give a novice programmer something to abuse, they will abuse it. Its about the first rule of computer programming. The only place I have used var so far is in the return from a LINQ query, I see no reason to use it extensively. So in short, I agree with you. Re: The use of 'var' SeMartens3-Feb-09 2:42 SeMartens 3-Feb-09 2:42  I absolutely agree with you. As I see it, every developer must be aware what he/she is doing. He has to know about the types etc. he is using etc. Using a paradigma like "Uh I don't know what the return type of this method is, but hey who cares, the compiler will do it for me" is not the way I agree with. So in my opinion the excessive use of "var" makes the code difficult to read, you always have to search for the last assignment... As far as I know, var was introduced only for the use with LINQ, but as you already said, it will be abused...

Brought back horrible memories of VB6 variant <shudder> Re: The use of 'var' Eddy Vluggen3-Feb-09 2:40 Eddy Vluggen 3-Feb-09 2:40  Well, I didn't declare a lot of "object x =" in .NET 2.0, doubt that I have more uses for the var-keyword. On the other hand, Resharper keeps reminding me that I should use "var" instead of the type-safe declaration. Ehr.. Dunno why actually I are troll Re: The use of 'var' Rob Philpott3-Feb-09 3:03 Rob Philpott 3-Feb-09 3:03  Eddy Vluggen wrote: Resharper keeps reminding me that I should use "var" instead of the type-safe declaration I know! Well, they've got it wrong. I hate the use of this subversive keyword. Fair dos for LINQ but no place elsewhere. Presumably you can tell Resharper not to do that, but I can't be bothered to wade through all the options pages. It does alsorts of things I don't care for - breaking my lines up, trying to use 'object initializers' to squeeze everything onto the construction line, putting space between casts etc. It should chill out a bit.
