There is a Collection Class called ArrayList. There are three methods: (Add, Insert, Remove). You can find this code example in Visual C# .NET Step by Step.
Quick Example:
ArrayList numbers = new ArrayList();
//fill the arrayList
foreach (int number in new int[12}{10,9,8,7,7,6,5,4,3,2,1})
{
numbers.Add(number);
}
//Remove first element whose value is 7 (the fourth (4th) index 3)
numbers.Remove(7);
//Now remove the element that's now the 7th element. index: 6 (10)
numbers.RemoveAt(6);
Hope this helps. . .

Hi.
I have VS 2003 on my computer and I am wondering if I can install VS 2005 also on my computer without uninstalling 2003. Can I have both VS 2003 and VS 2005 on my computer at the same time?
Thanks,

having following problem
i use a xmltextreader to read a xml document. After i construct it, i create a xmlvalidating reader based on this xmltextreader.
Then i create a xpathdocument on this object
XmlTextReader reader = new XmlTextReader(XXX);
XmlValidatingReader validatingReader = new XmlValidatingReader(reader);
validatingReader.Schemas.Add(XmlSchemaCache.GetInstance().GetSchema("MYSCHEMA"));
validatingReader.ValidationType = ValidationType.Schema;
XmlReader readerToUse = validatingreader
XPathDocument document = new XPathDocument(readerToUse );
document.createnavigator() --> here my code crashes.
why? in the incoming (XXX) xml file, the default namespace is missing. Now i can't add the namespace to the file manually. So my question is now, how can i add the namespace is added to the reader, before i do document.createnavigator, without using DOM.
i hope someone can help me out

I'm trying to figure out how i can access the source of a website or read the text right off the page. in more detail, i want to be able to run the program and have it automatically open up, lets say cnn.com (example), and do searches for html tags or words to load all the "latest news" headlines into a database for later access.

Do you want to use something like a RSS feed?
|
|
|
|
|
You can use an HttpWebRequest object to request a web page.

Hi, quick question.
Anyone know how to use quotes in c#.
In vb.net, I can write:
Console.Writeline ("This is a " & chr(34) & "quote" & chr(34));
which would output:
This is a "quote"
So how can I do it in C#?
PS: I need a quote ("), not a hypen thingy (')
|
|
|
|
|
You can insert meta-symbols directly into text after "\" symbol.
Your sample:
Console.WriteLine("This is a \"quote\"");

Hi Andy
Another possibility that I like is putting a "@" in front of the string.
THen you can show the "'s using double ""'s
For example:
string quote = @"Andy said ""hi!""";
this also lets you write backslashes without needing the ekstra backslash.
For example:
string path1 = "C:\\data\\text.dat";
string path2 = @"C:\data\text.dat";
now you have choices

- Those who can count..
- Those who can't!
|
|
|
|
|
another choice is this:
char quote = '"';
string str = "This line have " + qoute + " quote. " + quote;
result : This line have " quote. "
|
|
|
|
|
That code might prove quite inefficient, though. You risk that the compiler will box the char values, and the actual code produced will be:
char quote = '"';<br />
object[] tempArray = new object[] { (object)"This line have ", (object)quote, (object)" quote. ", (object)quote };<br />
string str = string.Concat(tempArray);

Hi,
I'm trying to import a tlb file, but always get the following error:
---------------------------
Microsoft Visual Studio
---------------------------
A reference to 'C:\Win32App\ingr\IDISP\bin\idisp.tlb' could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component.
---------------------------
OK
---------------------------
Yet, my colleague can import the same tlb correctly. I've tried it on another pc and it worked idd.
Crazy thing is, it didn't work some time ago, but in meantime I've re-installed my system, yet no difference.
What could be the problem? I'm still in training for our product, but this file is key in development soon...
TNX!
Coulda, woulda, shoulda doesn't matter if you don't.

Hi.
In a simple applicatin(Phone Book), I have 2 tables in my DB(SQLServer or Access).
A table for id,name,family and another for personID and tel.
now when I want to add a person, I must add record to both tables (name and phone),
but I don't know how can do it with C#??!! (with one command add to two tables???)
I'm beginner in DB !!
Best wishes

If you are using SQL Server then you can use a Stored Procedure[^] to populate both tables at once. You can also separate SQL commands with a semi-colon so that you can put two SQL commands into one SqlCommand object.
