You should use the XmlSerializer[^] class. The documentation contains examples of its usage.

Well, if you use XML serialization you can then create your objects from whatever source, serialize them onto your HDD and the opposite again.

happy coding

The other two posts suggested the right solution but i would like to add
that u have to design classes for that.
for example to load students directly from your XML file u need two classes
one contains the student properties whose each object represent one student and the other class to hold the collection of these student class objects

Well, you could invent some, I suppose.
Did you try google ? Who is this requirement coming from, do they have any idea if it's possible or not ?
There are webservices that can be used to send SMS, dunno if they work in South Africa. I guarentee that no namespace is going to magically connect you to the mobile phone network, how did you expect it to ?

Hi
i am working on .NET 2.0 winforms. in my form there is cancel button, in this event i am showing warning message "do u want to save the changes?". I need to show same message on when clicking on wikndow X button?
how can i do...
any sounds greatly appriciated

Check with the form events, it got some events which will fire when a form ends. Somethink like closed, closing etc
|
|
|
|
|
i will write the code in closing event. but if user will clicks on X button, and on No, then how can make window re-active?

There should be a "cancel" property in the event args of the closing-event. If you set this to true the closing will be - well - canceled.
|
|

|

Hi,
Form.FormClosing event is the prefered one since .NETY 2.0
set FormClosingEventArgs.Cancel true to cancel the close operation.
and maybe FormClosingEventArgs.CloseReason will be useful too.

I need to get data in treeview control from database while using multi threading.
|
|
|
|
|
... and the problem is?
I guess you've got an error while inserting items from another thread.
The sollution is to use the InvokeRequired - property of the treeview to query if you are calling from a different thread and if so using the controls Invoke-function to call a function that handles the actual insertion, here is a sample:
<br />
void FunctionCalledByThread( )<br />
{<br />
if (treeView1.InvokeRequired)<br />
treeView1.Invoke(new InsertItemsDelegate(InsertItems), );<br />
else<br />
InsertItems( )<br />
}<br />
<br />
delegate void InsertItemsDelegate( );<br />
void InsertItems( )<br />
{<br />
<br />
}<br />

Hello experts,
This is very frustrating, I post a message and near about 10-15 reply from me and and other code project members are their in the post.

And also when I goto my account and see the message posted (155). When I click on this only top 40 message displayed, When I click on next and previous button the page index and counting of post is also changed but same posts are displayed again and again...?
Where are my other posts...?

It was clearly posted in the lounge that posts on Sunday were likely to get lost. They did. The site has been updated, there are some issues, they are being worked on.

Hello everyone,
I am trying to get the IP Address of the client so the application can hook itself up to it. I am using the following code:
private void MyApplicationForm_Load(object sender, EventArgs e)
{
string strIP = null;
IPHostEntry HosyEntry = Dns.GetHostEntry((Dns.GetHostName()));
if (HosyEntry.AddressList.Length > 0)
{
foreach (IPAddress ip in HosyEntry.AddressList)
{
strIP = ip.ToString();
cmbInterfaces.Items.Add(strIP);
}
}
}
When I run the application on my PC which is connected via a cable to a routher I only get on IP address which is the internal IP address. But when I run the Application on my laptop which is using Wireless Connection to the same routher I get list of few IP addresses. Can someone tell me why this is the case and how can I make sure I only the IP address that my laptop is set to rather than the list of the IP addresses.
Thank you very much and have a great day.
