hi,

Hmm, i did this a thousand times but it doesn't point specifically to my application! Obviously RemotingConfiguration.Configure is running in a different thread but how to catch the exception in it?

e voila:

Unbehandelte Ausnahme: System.Security.Principal.IdentityNotMappedException: Man
che oder alle Identitätsverweise konnten nicht übersetzt werden.
bei System.Security.Principal.NTAccount.Translate(IdentityReferenceCollection
sourceAccounts, Type targetType, Boolean forceSuccess)
bei System.Security.Principal.NTAccount.Translate(Type targetType)
bei System.Runtime.Remoting.Channels.Ipc.IpcServerChannel.Listen()
bei System.Threading.ThreadHelper.ThreadStart_Context(Object state)
bei System.Threading.ExecutionContext.Run(ExecutionContext executionContext,
ContextCallback callback, Object state)
bei System.Threading.ThreadHelper.ThreadStart()

Further, this exception says that the system was unable to resolve the specified account. However i am fully aware of that and did intenionally use a wrong group. I just want to know
how to catch this security exception that is raised by the CLR.

Nope, that is quite alright. As i said, there is nothing wrong neihter with the program nor with its configuration. I just need to know how i could catch a security exception that is raised during the remoting configuration. I mean my entire application works perfect, unless i specify a group that doesn't exist. It is quite logic that the remoting configuration fails when i specify a nonexistent group but why is it impossible to catch this security exception?

Anyway, thanks for your efforts.

Passing variable

I have a portal site that incorporates multiple web parts. One of the web parts is intended to pass a query string to a search application located in another area of the intranet. My problem is thus...The search application is written in standard asp and the portal site is asp.net 2.0/C#, how can I link the two up and pass the string.

Any help, suggestions, or possibly a push in the direction of a reference would be greatly appreciated.

Thanks in advance,

Cheers

Ennis Ray Lynch, Jr.7-Jul-06 8:52

You can pass the variable around between the two with the query string(term? I don't write asp.net)
ie: http://someWebAddress/someSite.asp?searchString=some%20really%20long%20search%20string;
or
ie: http://someWebAddress/anotherSite.aspx?searchResult=some%20really%20long%20result%20string;

Thanks for the tip, I'd forgotten about passing data this way, I'm still rather new to this Smile | :)

I implemented the change and it is working well now, thanks.

You can use anything that you would normally use to pass information between pages, without storing the information on the server. Query string, form data, cookies.

Hi all,

I'm trying to write an application to deal with email forwarding (in the sense of being invisible to the end user) to a list of 100+ email accounts. I am using Indy.Sockets and a SMTP server provided by Fasthosts (standard mailbox).

I am having trouble getting the SMTP message to deliver to the addresses contained within the 'Resent-To' header ('Resent-From', 'Resent-Date' and 'Resent-Message-Id' are also being included). I'm having to add the 'Resent-To' header via the Indy.Sockets.Message.ExtraHeaders.Add() method as else the 'Resent-To' header seems to break-out into the main email, which results in an incorrectly formatted email (half of the 'Resent-To' addresses are shown in the body with the remaining headers).

Can anyone possibly offer any help? Or have successfully sent emails using a 'Resent-To' header?

Many kind regards,
Ben Whorwood

No update of ListBox after DataSourceChanged

Csharper20067-Jul-06 7:14

7-Jul-06 7:14

Hello!

I am a beginner in UI programming with C#. My problem: I have a ListBox on
a Form, that shall automatically update its content, when the data source
has changed.

I can fire the DataSourceChanged event in the data source class (which is
a derived ArrayList class) and also catch it in the Forms class. But
when I do there a ListBoxInstance.Update() or ...Refresh() ... or
Invalidate(), it has no effect at all. Frown | :(

Maybe someone can give me a hint on what I did wrong?

Here is the interesting part of my source code:

Form1.cs:

        private System.Windows.Forms.ListBox listBox1;<br />
        private System.Windows.Forms.Button button1;<br />
<br />
        // ItemList shall contain the content for the ListBox<br />
         private ItemList itemList = null;<br />
<br />
         public Form1()<br />
         {<br />
            InitializeComponent();<br />
<br />
            itemList = new ItemList();<br />
<br />
            itemList.Add(new Item(1,"One"));<br />
            itemList.Add(new Item(2,"Two"));<br />
            itemList.Add(new Item(3,"Three"));<br />
<br />
            listBox1.DataSource = itemList;<br />
            listBox1.DisplayMember = "Desc";<br />
<br />
            itemList.eventHandler<br />
                += new EventHandler(listBox1_DataSourceChanged);<br />
        }<br />
<br />
        // Is called, when ItemList has changes<br />
        private void listBox1_DataSourceChanged(<br />
            object sender, System.EventArgs e)<br />
        {<br />
            Console.Out.WriteLine("DataSource changed 2");<br />
<br />
            // try all ways to update the list...<br />
            listBox1.Refresh();  // no effect<br />
            Rectangle rect = new Rectangle(new Point(0,0),listBox1.Size);<br />
            listBox1.Invalidate(rect,true); // no effect<br />
            listBox1.Update(); // no effect<br />
        }

Item.cs:

   public class Item<br />
    {<br />
        private int nr;<br />
        private string name;<br />
<br />
        public Item(int a, string b)<br />
        {<br />
            nr = a;<br />
            name = b;<br />
        }<br />
<br />
        public string Desc { get { return "Nr:" + nr + " Name=" + name; } }<br />
   }<br />

ItemList.cs:

     public class ItemList : ArrayList<br />
     {<br />
        public EventHandler eventHandler = null;<br />
<br />
        public ItemList()<br />
        {<br />
        }<br />
<br />
        public void Remove(Item item)<br />
        {<br />
            Console.Out.WriteLine("Soll loeschen: " + item.Desc);<br />
            base.Remove(item);<br />
            FireDataChanged();<br />
        }<br />
<br />
        public void Add(Item item)<br />
        {<br />
            Console.Out.WriteLine("Soll adden: " + item.Desc);<br />
            base.Add(item);<br />
            FireDataChanged();<br />
        }<br />
<br />
        private void FireDataChanged()<br />
        {<br />
<br />
            if (eventHandler != null)<br />
            {<br />
                eventHandler(this,null);<br />
            }<br />
        }<br />
     }

When I call the methods Add or Remove in ItemList, the event is fired,
I can see the Console.out.WriteLine-Message, but the ListBox is not
updated...

Thanks for help Smile | :)

DataSource to null and then reassigning it works.

listBox1.DataSource = null;
listBox1.DataSource = itemList;

It's not a Visual Studio bug, this behavior is seen at runtime. It's not a bug at all, really. ArrayList doesn't implement IBindingList, which is the interface used by the WinForms databinding infrastructure to propogate change notifications from a data source to a control. The methods that CSharper2006 was calling on the ListBox have no effect on syncing the control with the data source. If you really want automatic change noticiations to propogate, use a data source which implements IBindingList.

So in his case he could just implement IBindingList in his ItemList class.

On second thought, that interface has a lot of methods!

I'm trying to write a program (C# .NET 2003) for use in my school, and so far it works pretty good.

The biggest problem I am having is that when I call MessageBox.Show(), no text shows up anywhere in the textbox, ncluding the title and OK button. This didn't use to occur, and then only on some computers, and now on every computer it is used on (including the design computer)

My computers have all of the Microsoft Updates, so I figured uninstalling .NET Framework 2.0 might help, but it was no good.

Here's my code if that helps:

MessageBox.Show(this, "MyStorage (C) 2006 IT Academy", "About MyStorage", System.Windows.Forms.MessageBoxButtons.OK);

MessageBox.Show("This should show something");

Neither of those work. The message box shows, and is perfectly functional, there is just no text.

If anyone can help, I would greatly appreciate it. I have to have this project finished by the end of this month, and this is my only real issue.

Thanks a lot

using System.People;

Person me = new Person();

me.Certifications = null;
me.Experience = little;
me.WantsToLearn = true;
me.InSchool = true;

Try this:

string message = "MyStorage (C) 2006 IT Academy";
string caption = "About MyStorage";
MessageBoxButtons buttons = MessageBoxButtons.OK;

MessageBox.Show(this, message, caption, bttons);

The title shows up now, but there is still no text for the message, and there is no text on the button...

Thanks, though. I'll keep trying.
