You have the right idea, but it depends on your actual XML.
I suggest getting the node directly and looking at it. This will help answer your question.
<names><Prenom>Dog</Prenom><Prenom>Cat</Prenom></names>
XmlNode node = doc.SelectSingleNode("//Prenom");
node.Value == null
node.InnerText == "Dog"

Hi!
The point is that while scrolling within a datagrid, sometimes the gridloses focus with no reason because I was just scrolling.The class below simply illustrates this(while scrolling you'll get a message)
Thank you in advance.
ps: I'm using vs.net 2003.

System.Windows.Forms.Application provides static function. I need to get 'this' instance of the Application, just like AfxGetApp provided in MFC, or the Application instance in VB.
Any ideas?
|
|
|
|
|
Hey !
In VB we can easily access the Application object. This is also available in MFC as AfxGetApp().
What is the C# .NET equivalent?

Hello, I want to make a dialog with a given size for pocket pc.
For doing that I have derived my class from System.Windows.Forms.Form and I have set the property Size for my form with my prefered size. But the result is not what I have expected.
Do you know what can be the solution for my problem?
public class SelectionTool : System.Windows.Forms.Form
{
public SelectionTool(String title, String lblText){
InitializeComponent();
}
private void InitializeComponent()
{
//that line of code doesn't set the size for my form
this.Size = new Size(20,40);
.....
this.ShowDialog();
}
}

I am C# beginner. I just started to practise
on console aplications.
And I already have problem.
How to supply C function _getch()
i.e. Get a character from the console.
Thanx
viliam

Your best bet is probably to write a DLL in C that performs any low-level input, then use the Platform Invoke feature to access that.
You can also P/Invoke _getch directly.
[DllImport("msvcr71.dll", CallingConvention = CallingConvention.Cdecl)]
static extern int _getwch();
[STAThread]
static void Main(string[] args)
{
Console.WriteLine( "Press any key to continue" );
Console.Out.Flush();
char ch = (char) _getwch();
Console.WriteLine( "You pressed {0}", ch );
}You must call Flush, because the Console class performs buffering on the stream. Failing to do so can cause the prompt to be displayed after _getwch executes, not before.
Note that I used the wide-character version, _getwch, because the CLR uses wide characters internally.

What about Console.Read() ? Doesn't that work?
|
|
|
|
|
|
Oh ok... I guess I missed the point of the post. 
|
|
|
|
|
Actually I don't think you did... I'm sure he just wants to read some character from the console...

Hi,
I would enjoy playing a short custom sound with C# (like a beep) when the mouse moves over a button for example, like Ineternet Explorer does.
Would anybody help me ? Thanks.
|
|
|
|

Use managed DirectX or use P/Invoke to call the play sound method in the Win32 API.
The graveyards are filled with indispensible men.

Hi all.
I'm trying to set the IP of my NIC's. I have found nice examples showing how to get the IP through the WMI, but how can I set it?
All hints are appreciated.
Regards,
Christian Sternell

As far as I know, you can't without going through the natice API, and configuring it with no DHCP, and then setting a static ip address.

Thanks for the answer, Giles.
That was a little discouraging, but I'll see what I can do about it.
If anyone out there has a piece of code for this - please post if for me.

I'm pretty sure I had a friend do it in C++ once using WMI (NetworkConfiguration class). If you can do it in C++, I would assume you could wrap it in C#.

Can I compile my c# application under MacOS-X? 
Bye, Roberto Ferro

Yes and no.
If your application contains no GUI then you can most likely compile the appliaction for Mac OS-X. However you'll need a different version of the .NET Framework to compile your code. Check out www.go-mono.com[^]
If your application contains any GUI code then it will be much less likely to work with Mono

Mono only runs on windows and GNU Linux!!!
Get Portable.NET, runs on anything

Probably 2 choices , Mono by Ximian, or Rotor, which is a shared source implementation by Microsoft that compiles on Windows XP and Free/Open/Net BSD Unix's.
Mono on Linux makes use of Wine to do the GUI bit, though I have no idea about Rotor.
