That was my first thought too, but maybe he wants to put some link in his windows application (wouldn't be that unusual). Hard to tell with this kind of phrasing, so I just gave it a try.

The user's language can be found via the "Accept-Language" HTTP header in ASP.NET 1.1 (get it via Request.Headers), and then you can redirect or use some kind of custom language adaptation. For ASP.NET, you can do localization easily through resources - see here[^]. On the client side, you can use var langCode=navigator.language? navigator.language : navigator.userLanguage;.

VisualStyles Namespace Query: Elements not Defined

I am writing a custom header control and want to support themes using Microsoft's new VisualStyles namespace.

The problem is that none of the Header.ItemLeft or Header.ItemRight elements are defined, which draw the empty parts of a header control.

Running a native C++ app that displays visual styles I can see that these styles are defined and render correctly.

Does anyone know why these elements would be undefined in .Net?

I know there are UxTheme wrappers for C# but would like avoid using these if possible to keep the project dependencies to a minimum.

I am developing in VS2005, Windows XP sp2 and use the Olive Windows XP theme with no modifications.

Outlook Add-In using Redemption

Has anyone got any experience using Redemption to access the Outlook address book?

There seem to be lots of articles on using VB but trying the same approach in C# simply doesn't work

I'm wanting to walk through the entries in the address book to see if they are the sender, spam filter type stuff.

Currently I'm trying this:-

Type t = Type.GetTypeFromProgID("myRedemption.myRDOSession");
Redemption.RDOSession mySession = (Redemption.RDOSession) Activator.CreateInstance(t);
mySession.Logon(oMissing,oMissing,oMissing,oMissing,oMissing,oMissing);
if (mySession.AddressBook.AddressLists(false).Count > 0)
{
etc etc etc
}

On entering the if statement I get an Object Exception on mySession and I can't see why.

Anyone?

Can't it be done through the Outlook Object Model? I believe the Outlook Object Model exposes a Contacts Interface.

Hope this helps... Smile | :)

It can but you get the security message so it isn't suitable.

Thanks though,

Is that the same security message that pops up when an email is sent trough Outlook via code? If yes, then if the original Application object from Onconnection is used, the Security popup doesn't pop up.....

Hope this helps.... Smile | :)

Is there any Hash Table in C# and if yes then how do we use it? How do we add and how do we look up in hash table?

Yes, class Hashtable

<br />
Hashtable hash = new HashTable();<br />
// Adding value.<br />
hash["key"] = 0;<br />
// Getting value.<br />
MessageBox.Show(hash["key"].ToString());<br />

You can also access data through properties "Keys" and "Values".

Best regards, Alexey.

Hi,
yes of course, by using the "Hashtable" class.

Hashtable myHashTable = new Hashtable(); to instantiate a Hashtable object.
myHashTable.Add("theKey", "theValue"); to add an element
myHashTable["theKey"]...; to retrieve a "value" usig its "key"
myHashTable.Keys; to retrieve the Keys Collection property
and myHashTable.Values; to retrieve the Values Collection property

Regards.

By the way, you can look up the hashtable by

Hashtable.Contains()
Hashtable.ContainsKey()
Hashtable.ContainsValue

as well.

Use windows authentication in client/server application

Le Thanh Cong13-Apr-06 20:35

13-Apr-06 20:35

I write a application client/server (windows form). Both client & server run in a Active Directory domain. When client connect to server, server will get IP of client. Base on IP, server check current user logon in client PC, determines if the user has been authenticated by Windows.
At client, I can use System.Security.Principal.WindowsIdentity.GetCurrent() to authenticate user but at server, I don't know way authenticate remote user.
In case, what is solution? System.DirectoryService?

Ummm, there's no need to check to see if Windows authenticated the person or not. If the authentication failed, that person would not be logged onto Windows, and therefore, there won't be a user logged on.

All you really need to do is on the client side, pass the clients WindowsIdentity (use GetCurrent), to the server. The server will then have everything it needs to know about the user.

About EndInvoke

13-Apr-06 15:09

I happened to find that in the provided libs of my program, many thread are invoked just by BeginInvoke without callback to do EndInvoke. Waht will happen to a thread in ThreadPool if EndInvoke is not all at all?

Asyncs threads invoked by BeingInvoke are used in my program to send event, many I often enfront the problem that some events seem to heave disappeared in the middle of that thread.

I will add EndInvoke code to all these threads. But I hope that I can get some confirmation befrore doing that.

Thank you !

As I understand it, EndInvoke() is used to obtain the return value of your delegate method. If your delegate method is of type void, a call to EndInvoke() may not be required. if you haven't already, see this[^] article.

Thank you very much.

But I was told that BeginInvoke and EndInvoke should be called in pair, otherwise memory leak may happen in program.
I have checked topics on ThreadPool the other day, and I found that threads invoked by BeginInvoke are not so simple.

Of cause, I haven't found any such discription in MSDN articles, just on some forum. But the fact is that my program do stop at somethere in the invoked thread (maybe for some other reasons).

As the detail of ThreadPool is not opened completely, now I am considering of writing a ThreadManager of my own, just start a thread by Thread.Start(), if necessary cancel it by Thread.Abort().

In the following artical, it says

CAUTION Always call EndInvoke after your asynchronous call completes.

http://www.interact-sw.co.uk/iangblog/2005/05/16/endinvokerequired[^]

what will happen if EndInvoke is not called?
