How can I get an XmlNode from an XmlTextReader. What I really want to know is this.
Here is my XmlTextReader
XmlTextReader xtr=new XmlTextReader(this.textBox1.Text);
Now, I want to use this method, but I can't get an XmlNode out of xtr. What do I do?
public void LoopThroughChildren(XmlNode root)
{
this.listBox1.Items.Add(root.Name+ " \t\t\t"+root.FirstChild.Value);
foreach (XmlNode n in root.ChildNodes)
{
if (n.NodeType == XmlNodeType.Element)
{
LoopThroughChildren(n);
}
}
}
I was using an XmlDocument but my xml file is too large to use it anymore... So basicilly can somebody help me write a recursive method that goes though an entire xml file?

Nevermind, I just realized how dumb my question was...

Have you thought about using XPath to select from your XML document?

nope. I don't know what that is.

There are a series of classes within the .NET Framework that support XPath. Read the XPath specification at the W3C[^], there are also a bunch of useful articles that may be more easy to understand that can be found on Google. This[^]
might be the easiest way to get started.

Just you opinion here... Do you think this would be a better substitute for parsing a huge XML file into a database and then running queries on it???? Running xpath queries sounds pretty nice.

Actually, i need some little help because i'm facing a "high-level"  problem ( i call it that, because it is not a familier or ordinary problem).
I was able to export a shockwave flash file into the C#
environment by a certain COM component, then i added some
fading features to the generated exe by making use of the
opacity and about 3 timers (the exe file has 3 forms).
The problem is during the execution, i pressed Ctrl+Alt+Del and i was surprised to see the Memory Usage of my file to be about 13 MB  , which increases to about 17 MB  when i call the other forms to appear (like the "About me" form)!!!
The most strange thing is that my file is really small in size, 136KB!
Is the cause for this, the usage of timers or what? and is there anyway through which i can decrease the mem usage, because this size is large indeed,,,

"export a shockwave flash file into the C#" using com+ will increase the memory usage of your app-form, since the flash is costing, and com+ loads other dlls which is necessary to run the flash exporting com+ dll. memory usage is not necessary related to the file size, it depends how it runing, how many extra resources which it bring up during the running process.

First off, quit yelling!
The problem is not beacuse of the Timers, it's because your running a Managed app. 13-17MB is not uncommon for a Windows Forms managed application. You file size is 136K because it's IL code, not an executable. The IL gets translated into machine code by the .NET Framework and runs in what is essentially a virtual machine. The large memory footprint is the overhead of the .NET Framework and, no, you really can't make it any smaller.
You really don't have to worry about the memory footprint because it is managed by the Framework's Garbage Collector. I would HIGHLY suggest reading about it here[^]. It runs a bit lazily and won't clean up objects and free memory right away unless your machine start running low on memory.
I've got an app, puzzle solver really, that will consume about 2.3GB, yes GB, of memory at it's peak, even though the executable size is a mere 52KB. It beat the hell out of the GC so bad I had to write in my own memory manager to handle forecasting and pre-allocating array space.

I would love to see this as an article, that would definitely be interesting.

2.3 GB? I thought a process under a 32-Bit windows could consume 2 GB maximum...

I believe that limit applies to any single object, not a process.
SQL Server can run WAY over that limit quite easily.

hi,
could somebody just do this for me, what it is that i have this homework assignment that i need to have in by monday and i haven't done anything or even written any c.
What i need is a piece of software that uses a global positioning system to map out various areas of the world which you can zoom in and out on. Then pin point certain areas and go into buildings and then start planning the furniture.
This should then be able to create several documents - letters spreadsheets detailing this and providing area managers with the plans and a cover letter.
If anyone can do that for me by monday thanks

You need to look into javascript so this can be done on the client side. Please ask your question on the ASP.NET[^] forum.

Does anyone know where I can find any examples on using SslStream class from .net framework 2?
I'm trying to do secure socket connection, but I'm not sure what are the steps necessary.
I have a certificate file (.pem), but I'm not sure what steps to take.
I tried using Socket
TcpClient client = new TcpClient();
client.Connect(address, port);
SslStream sslStream = new SslStream(client.GetStream());
but I'm not sure how to use the key file. I think I have to use X509Certificate class somewhere.
Thanks.

hi
I'm trying to display a datagrid the way most windows applications do, that is:
with one last column, that is disabled, and has no title, and it's size allways goes to the end of the display area (if the grid doesnt fit, the with is 0, i asume)
and with empty, disabled rows at the bottom, untill it reaches the end of the display.
You know, like the windows explorer when it's showing files in Details mode.
Any idea how to do this?
thanks

I have written a windows service that starts automaticaly on windows boot and it do some jobs.
If I restart PC, or if I log off and then log on again my service is still started but is not working anymore.
My service use another service that is written from another manufacturer (this service can open communications to some hardver devices and communicate with them). It seems that on booting my service starts before that service it depends on, so it is not working (I suppose that is because on starting my service call that custom service to open communication to devices and after restart or log off I lost these opened communications to hardware devices that are controlled by that custom service).
How I can set that my windows service depends on this service? (I know the path of EXE file of that custom service and this service is listed in services.msc).
I see in C# initialization of windows service array ServicesToRun - so how I can reference and load that service I depend on to load before my service)?
I hope that it will resolve my problem...

Within the Service Control Panel, you can set dependencies within the properties page.
Window will only start your service after the dependency has started.
|
|
|
|
|
If I start services.msc and then right click on service, and
then if I go to Dependencies tab I can just see the services
that this service depend of. How I can add some service? Don't
see any add, or on right mouse click... (Windows 2000 Professional)
