Thanks for the reply,
The Serializable attribute and ISerializable are connected with regular serialization, not XML serialization. So marking the class as Serializable or implementing ISerializable won't solve the problem.
As for IXmlSerializable, it would probably work, but I would have to implement my own xml serialization routines for the LinkedList, which would lead to adding an amount of unnecessary code (and I would need to do the same for other collection classes, like List<> or Dictionary<>, which also cause the same problem), and it's not what I would want to do.
If I won't find any other way to solve this problem, I think I'll just use a BinaryFormatter to serialize this class.

In my example, it is true that implementing ISerializable is unnecessary, but you would still have to implement the constructor that normally goes along with that interface (or you would get a deserialization error if you attempted binary serialization). I think that in the .Net 3.0 framework you can add extensions to classes that you would otherwise not have access to, so you may look into that if you have the 3.0 framework available to develop against. Using this methodology, you could add the methods implemented by IXmlSerializable to the actual collections, but I don't think you can add interfaces (like IXmlSerializable) to the inherited interfaces list. Anyway, good luck, and let us know if you do find an elegant way to go about this.
Sounds like somebody's got a case of the Mondays

Hi,
I want to develpe a windows application that should be executable in a LAN.
a computer is as server, and another are clients.
Now, I develope it just a standalone application,i.e:
I install application on each client and instal SQL Server on Server and clients use IP address of Server in its Connectionstring
Or I should develope it in another approach?
I don't develope such application before that must be ran in LAN.
Best wishes

You have the basic idea. It could get more complicated depending on the requirements.

Hi:
Sorry , I didn't mean that , when I run my form , inside it there are many radio buttons , when I choose a value , I want this value directly stored in a txt file ........
Thanks

Handle the selected event and write it to your file.
It would be nice also if you took out all the empty space on your signature line

Hello :
Thank you very much for your intersting , but can you give me an example to do that or explain the steps to do that ,please......
Thanks

How about at least try something on your own? What part are you having difficulties with? Handling an event? Writing to a file? What? These are not complex topics.

Perhaps it was the "taking all the empty lines out your sig" part.

Hello :
I'll try it myself , but I want to know how can I start deal with handles and write to a file ......
Thanks

There is a little textbox at the top of the page, the one that has Search next to it. You should try it.
If you find that difficult, perhaps another career would be better.
Take the empty lines out of your signature.

This should get you started.
void button1_Click(object sender, EventArgs e)
{
foreach (Control thisControl in Controls)
{
if (thisControl is RadioButton)
{
RadioButton thisButton = (RadioButton)thisControl;
if (thisButton.Checked)
{
string path=Environment.GetFolderPath(
Environment.SpecialFolder.LocalApplicationData
) + "\\test.txt";
TextWriter textWriter = new StreamWriter(path);
textWriter.WriteLine(thisButton.Name);
textWriter.Close();
Console.WriteLine("Data written to " + path);
break;
}
}
}
}
Now use this to get yourself going and post back with a more specific issue if one arises - and alter that signature!

 Rather than learning some very simple techniques, all he has to to do is copy your code. Hope you will always be around for him. Give him a fish, feed him for a day; teach him to fish...

I take your point and I agree totally, but if he is to learn some simple techniques he needs a starting place. What better place than here? Surely that's part of what CP is about.
You'll notice the code I gave is very vague and pretty much useless. To be put into a pratical situation it would need some significant alteration that would require, and hopefully stimulate, a proper understanding of the code I gave.

Hello
I want to thank (DaveyM69) about the support, and your advance (Mark Nischalke) is nice but I hope you too when you look at it you didn't copy it, it's a disscusing forum, so what is this forum do if we don't sharing information between us....
Thanks

NaN - Not A Number?
Try converting all those strings to decimals before doing any calculations and/or comparisons.

Hi everyone,
I have always held some kind of a fascination with the resource editor in Visual Studio. I could never understand how VS allows a user to drag/resize/modify buttons, edit boxes, and other controls on a dialog inside a window.
Can anyone throw some light on the matter?
Thanks!
