zip lib for .NET - SharpZipLib
And I never heard about free fullfunctional rar lib...
By the way, UnRar.dll supports extraction from password protected files. At least, my password protected rar archive was successfully extracted using sample solution, coming with unrar.dll...

Hi,
I am using Microsoft.Web.UI.WebControls.TreeView control in my application.
I am able to add new nodes and child nodes to it, but the problem i am facing is that i always get the selected node id as 0, i.e the id of the first Node.
All events have been written for it, autopostback property set to true, but am not able to access the selected node id. Even the event for the selectedindexcgange does not fire.
Due to this i am able to add child nodes only to the first parent node.
I am using a right context menu, and on right click on a particular Parent or child node, different operations like Add child node, rename and delete can be performed on it.
All this can be accomplished once i get the selected node id.
Can anyone please tell me as to how to proceed with this?
Thanks

I have a progressbar showing the progress of background operation , when i browse through other application and return to mine , the form takes time to redraw itself infact it is redrawn only when the progress is completed.
I went through various sites and found that this problem in delphi can be solved by using..Application.ProcessMessages...Any ideas do it in c#.

not sure how you are going about it, is it threaded ?
are you looking for Application.DoEvents() ?
need more information about your implmentation.
there is another post (recently) about how to achieve this with a backgroundworker thread

yeh with backgroundworker everything is fine....
wat I m trying is just a "for" loop whose value goes to progressbar.value using thread..then thru invoke function of threads...showing the progress in progressbar but while progressbar is working and u browse other application the windows form of mine take time redraw it self (it does not response from user)..want to make form responsive even if progressbar is functioning

If the operation is really done in a separate thread and the GUI thread isn't blocked otherwise this shouldn't occur. You should first check if you are really using your threads correctly and if the main thread is working on something.
Other than that (as already suggested) you can use Application.DoEvents() to make your form redraw. But be careful not to call this too often (with 'often' I mean many times per second) as it might reduce performance.

Thanks Robert and goofyman...Application.DoEvent()..works.

I have requirement of reading a remote file using ASP.Net (C#)

Can anyone pls luk into this

ASP.NET code is not run using your user acount (why would it), but a special account. The name of the accound depends on the version of IIS, but it's normally ASPNET or IIS_WPG. You have to grant permission to the file for this account.

Ya Guffa , this makes sense....but how do I grant these permissions to the file...Can u pls help
Thanks,
Deeps

Open the properties for the file and go to the security tab. If the user account is not listed, add it. Set read permission for the account.

Hi all,
Thanks all of you for the replies. Thought to post the solution if anyone needs it. Access a remote file through Asp.Net is different from doing it thro a console or win appl as Guffa rightly pointed out. So to do this there is a class WebClient which can be used
Here's the code snippet
WebClient myclient= new WebClient();
Stream st=mycl.OpenRead(@"http://machine-name/filepath");
StreamReader sr=new StreamReader(st)
...
Then startreading the file using the streamReader.
Thanks
Happy Coding
Deeps
Thanks,
Deeps

That method is fetching the file using the HTTP protocol via IIS, instead of using the file system. That means that the file has to be publicly available (which is not always good), it adds a lot of overhead, and it increases the traffic through IIS.

hi can anyone tell me that when we provide a url and port number in object of TcpClient class what happens. I have defined the url as
string url="127.0.01"
intport=8888;
and then i have passed this way
TcpClient socketfor=new TcpClient(url,port);
can anyone please let me know the meaning of it.
|
|
|
|
|

The call will try to establish a Tcp connection to the specified url and port. The url is used to know to which host (computer) the connection should be established. The Url can be a normal adress (like http://www.codeproject.com) or like in your case an ip adress (actually the first one will be resolved to an ip adress on the fly). The ip "127.0.01" is always the local machine - thus the connection will be established to yourself. As every host can have multiple connections open the port number differentiates these connections.
Probably this description is a bit too simple (I'm no real expert on this) but it should give you a rough idea.

hi all,
i have an app and am wondering the best way to periodically check for updates or other events.
should i use the windows scheduller or just have a thread that sleeps alot? or another way?
which is best practice?
more often than not the period between checks would be once or twice a day. this i think is along time to sleep a thread.
any ideas pls?
kind regards,
g00fy

Personally I wouldn't use the scheduler. You have more control when doing it yourself.
You could even avoid having your own thread by using a System.Threading.Timer[^] class which manages this internally.

Hi
Is it possible to have a check box in a listview (windows application) column header and while checking this, all the check boxes in the column will be checked?
|
|
|
|
|
I don't think it is..
You could either drop a small button on to although that would be rubbish.
You could hide the column headers and have the first row of data being a dummy row, when you check its checkbox it checks all the others.

i have this column in an excel worksheet that contains hyperlinks to other documents. the rest of the columns contain regular values (e.g. Roger). the whole worksheet iotself would be exported to a datagrid using c#.getting these regular text values to display is fine but the probelm is that i can't get the url behind the hyperlink...
help me please.
thanks.

How are you fetching the data? If you do it with OleDb you probably won't have any luck. I think you need to use the Interop assemblies for Office.
