Hi,
If i want to perform a search using the function SelectNodes(), can i specify an XPath to search for the node's value instead of the node's name?
Thanks

yes, you use = to specify a value.
"/XML/value[@attrib='this']"
That returns nodes under XML/value that have an attribute ( that's what the @ means ) named this.

Dear all
i'm a student working on a project that i have to deliver real soon and i'm running out of time
my project includes building a graph for web pages of my site and compute connected components
so i'll have to work with connected components algorithm or incremental connected components
i found quick graph library in this site but i have difficulty working with it
in building the graph
i want to add vetrices to the graph dynamically
as select page names from database table and add it to the graph
as i got when working with adjacency graph i write
VertexStringDictionary names as new VertexStringDictionary
IVertex u = g.addvetrex();
names(u) = "u"
but what if i want to use an iteration for table records as name for IVertex dbvalue = g.addvertex
then names(dbvalue)= "dbvalue"
then what can i do after that to apply connected components algorithm
please help me urgently i'm in bad need for help
accept all my regards

Sounds like you need to post in the forum provided by the article author, and see if he can help.

Hey everyone,
My application refused to use Copy/Paste feature. I did not write any special code for copying text to the clipboard, since the control is WebBrowser (.Net 2.0). On other machines, Ctrl-C just copies the text to clipboard without any need for additional code, like manual clipboard handling. On my machine, the clipboard did not change its contents. I renamed my Documents and Settings folder and relogged in, thus recreating my account and, more specifically, UserData folder. I can now copy text into the clipboard just fine. However, there are other people having the same problem, so I need to identify the source of the issue, since deleting UserData is not an option. Any suggestions? Is it system permissions for .net?

Check the settings for the internet cache, the maximum disk space is usually set way too high. When the cache gets too large, it f... messes up some things in the browser. Clear the cache and set it to a reasonable value, like 50 MB.

Hello, all. I've published some simple stuff, and tried to send it/put on a CD, but every time the other person tries to use my program, it says 'missing files'. What's the problem here? Am I publishing like an idiot? I found nothing on google and more, and though I'd just ask the pros. THanks in advance.

You've given them your config files, and they have .NET ( the right version ) installed ?

I don't think I expained well;after I publish, I copy the files to a disk (is it disk or disc... anyway), and then I go to another computer, put the dis(c) in, and run it. When you try to run the file, it says something along the lines of "Missing files or components"... Something. I don't know what I'm doing wrong.

You should create a Setup Project for your application. This allows you to build an installer that includes the .NET Framework Redistributable. Running the install app on a client machine will install the .NET Framework on the machine as well as your application if it is not already present. Have a look at this article[^] for more information.

Yes, I got that. So, you missed some files, or you're missing a dependancy, such as .NET. Have you installed the .NET runtime on the target PC ?

Shouldn't programs for Windows be able to run on any PC they're tried?

You're assuming a lot there. The answer is no. Anyn application written in C++ needs the MSVC runtime libraries to execute, whether they be staticly linked into the .EXE or seperately in the Windows\System32 folder. The same is true for MFC apps, VB6, C#, VB.NET, ..., or ANY application. Some of the runtimes are already installed with Windows, some are not.
The .NET Framework didn't start comming preinstalled with Windows until Windows Server 2003 came out. I think it was included in Service Pack 2 for XP, but I could be wrong.

So, where would I install this?

There is no "where". You run the installation for the .NET Framework version you're app is using (.NET 2.0 for C# 2005) and it installs itself. You don't get to specify "where" it installs.

Hi, all...
I'm writing the Multy Dimentional Matrices by analogy with Matrices, which describe in book of Bjarne Stroustrup ("The C++ Programming Language: Standart 3")
I have class "ValueArray", which implements "valarray" (C++ analog), and "Slice", SliceArray, etc.
I already wrote two dimentional Matrix, but Multy Dimentional Matrix it's problem...
If you read Stroustrup, you saw that there were no implementation of this.
How realize this using "ValueArray" and "Slice" on C# or C++???

Do you have a budget?
My office is using this fantastic library:

I am writing an application for CE 5.0 and I need to save (and recover) an array of structures to file. Serialization seemed to provide the solution, but it is not supported in the .NET Compact Framework. Can anyone suggest an easy way of doing this?
|

I guess you need to define your own file format. I'd use XML, then it's easy to turn the data into a collection of objects that each represent one object to deserialise. I'd write methods in the object to write and read the XML, so you can compartmentalise it easily, your main write code just iterates over the objects and lets them write themselves, your read code, creates a collection of objects by calling the FromXML static method for each node set that represents an object.

XMLSerialization is supported by .NET Compact Framework if it fits your needs
|
|

I'm going to have to concur with Giorgi - XMLSerialization should do the trick. I'm using it on a .NETCF app and it's great. I just adorned my objects and their properties with the appropriate Xml attributes and the XMLSerializer does the rest.

Thanks, XMLSerialization is just what I need, but I don't understand the bit about attributes. Could you please provide more information, or tell me where I might find it?

Sure!
The XmlSerializer by default will serialize an object's public properties and fields using the names in your object.
Say you have an object called Person, and it has a Name and a Gender.
public class Person
{
private string mName;
private string mGender;
public string Name
{
get;set;
}
public string Gender
{
get;set;
}
}
By default the XmlSerializer will create something that looks like this:
< Person>
<Name>Whatever</Name>
<Gender>Whatever</Gender>
</Person>
But you can adorn the object to change the way the object is serialized. For example, if you want it to be serialized as a "Human" and the Name and Gender properties to be XML attributes instead of XML elements:
[XmlType("Human")]
public class Person
{
private string mName;
private string mGender;
[XmlAttribute("Name")]
public string Name
{
get;set;
}
[XmlAttribute("Gender")]
public string Gender
{
get;set;
}
}
This will create XML that looks like this:
<Human Name="Whatever" Gender="Whatever" />
You can read more about the XmlSerializer and how to use it here:
