Well, if you want to access the add node, just drop the rest of the XPath - /details/add
If you want to get all the addr nodes, name them all addr, as I advised you to do in the first place.

Hi. I have written a code that has no recursive function in Visual Studio.NET 2003(C#). It personalize a smart card. After it personalize some cards(24 for one system, 60 for the other, 18 for another), it ends with a stackoverflow exception. I use WndProc in my project. When the unhandled exception occurs, it breaks in the end of WndProc. How can I find when this error occurs and how can I solve this error?
Thanks in advance

your program is recursive in some way, which is causing the problem. It doesn't have to be a single method that is recursive, it might be methods that call each other in turn.
The only time the stack usage changes is when you call a method, and when you return from the method the stack usage returns to the previous state. That concludes that the only way to get a stack overflow in the way that you do is to call methods that you never return from.

Hello
I can't remember all details now, but below code can help you.
Please add to your project PrintDocument Control from toolBox and name it printDoc.
<br />
using System.IO;<br />
using System.Drawing.Printing;<br />
using System.DirectoryServices;<br />
<br />
string strDefaultPrinter = printDoc.PrinterSettings.PrinterName ;<br />
<br />
foreach(String strPrinter in PrinterSettings.InstalledPrinters)<br />
{<br />
listboxPrinters.Items.Add(strPrinter);<br />
if (strPrinter == strDefaultPrinter)<br />
{<br />
labelSysDefPrinter.Text = strPrinter ;<br />
}<br />
}<br />
but notice that I think you should first add network printers from Start Menu \ Printers and Faxes.

no...it display only one printer... but my network has 2 printers...and in my system it contain 2 printers(setting-->printer-->)

The way you word these, it sounds like you're reading them off your spec documents at work.

That was my first google hit, by the way. So, you just add the menu items according to what you're shown on that page.

OK, I have some questions
1 - are you being paid to write this code
2 - are you typing these questions in from your clients specification
3 - what part of what you typed above is confusing you
4 - how long have you been coding for
The best long term answer to this specific question kind of depends on how you answer my questions.

OK, if you won't answer then I'll limit myself to saying that showing a dialog box and collecting a name is a very trivial task. If this is homework, you should pay attention in class more. If this is work, you should speak to your manager, not least because he needs to know that you can't do this on your own.

Hi,
Im used to adding controls like radio buttons on web forms in a PlaceHolder ,
1.Is there a similar control on windows form as well otherwise how can I add controls dynamically on a windows form.
2.And if I add RadioButtons I need to group them by a 2 by 2 array..
In VS 2005 there is no group property for radio buttons... How do I do it?
Help plz..

1 - There is a panel, but in Windows Forms, you can specify the location of your control, so it's not really needed
2 - Group them by placing them where you want them to be.

2. I wnat group them in 2 by 2.. like
radButton1a | radButton1b
radButton2a | radButton2b
radButton3a | radButton3b
etc... Like I want radiobuttons 2 and 3 to be independent of 1... When I check radButton1b, only radButton 1a should be unchecked..
I hope I explain...

I dunno if there's an easier way, but perhaps you need to create a control that holds two radio buttons, which will group them seperate from the rest of the form ?

My problem for school...
Write a program that has five text boxes numbered 1 through 4 and Result. After the user types something into each of the four text boxes, display whatever was typed into each in a 4-3-2-1 order in the Result text box.
I know how to do everything except outputting multiple numbers to a single text box. So far I have...
private void btnCalculate_Click(object sender, EventArgs e)
{
decimal number1;
decimal number2;
decimal number3;
decimal number4;
decimal result;
number1 = decimal.Parse(txtNumber1.Text);
number2 = decimal.Parse(txtNumber2.Text);
number3 = decimal.Parse(txtNumber3.Text);
number4 = decimal.Parse(txtNumber4.Text);
Do not make fun I am an extreme beginner trying to learn C#. I'm sorry for posting such an easy problem, but I couldn't find anything relevant on the internet or in my book. Any help would be greatly appreciated!

I don't want to give too much away (since it's a school project and all  ), but you might want to look into the TextBox's AppendText method.
P.S. There's certainly no need to apologize for asking beginner questions; everyone starts at the same level.

I'm trying to implement the code found here:
http://www.codeproject.com/cs/files/recursivefileexplorer.asp
but I've hit a bit of a wall. I've got the following code in my project:
FileExplorer fe = new FileExplorer("C:\\boo");
FileData FileData = (FileData)fe.FileList[0];
but I keep getting the error: "...fe denotes a class where a field is expected"
I'm sure I'm not doing everything correctly, could someone give me a hand with this one?
Thanks in advance,
-Sean

It appears as you have used the name "fe" for a class in your project also.

Hi,
I am trying to start my email app (in this case Eudora) with a programatically generated email. However, Eudora does not seem to recognize any of the ways I have tried to create line breaks.
I have tried "\n", "\r\n", and using the StringBuilder AppendLine() method like this:
StringBuilder body = new StringBuilder(1024);
// AppendLine doesn't work
body.AppendLine("Thank you for registering!");
// Neither does this
body.Append(System.Environment.NewLine);
body.Append("Support Forums");
body.AppendLine();
body.Append("Please be sure that you have the latest version, ");
Process process = new Process();
process.StartInfo.FileName = "mailto:";
process.StartInfo.FileName += tbEmail.Text;
process.StartInfo.FileName += "?subject=GaugeGlow License Key";
process.StartInfo.FileName += "&bcc=benchmark-avionics@comcast.net";
process.StartInfo.FileName += "&body=";
process.StartInfo.FileName += body;
process.Start();
yet, when the email opens in the application, there are no line breaks at all.
Thanks,
Stick

I have a program that if it encounters an error, it asks the user for a new value from a new form. How can I pause execution so that when the User presses the button on the new form it continues execution on the original form?
