Copy All items from One Listbox to another Listbox

Hi,

I tried to copy all the entries from one listbox to another.

I do not want to loop through the listbox to move each one at a time.

Is there any way?

Yes. The ways is

ListItem[] items = new ListItem[ListBox1.Items.Count];
ListBox1.Items.CopyTo(items, 0);
ListBox2.Items.AddRange(items);
ListBox1.Items.Clear();

Without Debug Application Everytime in VS 2005

If you working in Visual Studio 2005 web application, then you might face that Open your application in the browser without Debug your Huge project Everytime. Only one time debug is enough. When you work in VS2003 your all files are in IIS default folder so if you type http://localhost/project/default.aspx, it will open that page.

But in VS2005 even if you know the URL like http://localhost:1345/default.aspx you cant access the project without debug.

I have found one method to debug your application at this situation. Open the project in VS2005 go to Website menu => Asp.net Configuration. It will open Website Administration tool. Now your project Ineternal IIS started for your project. You can access your project through URL easily
