You could alway use regular expressions.

Try using this way
string myString = "<rssfeeds>http://www.codeguru.com/icom_includes/feeds/codeguru/rss-all.xml"
+ "<title>CodeGuru.com<description>something<rssfeeds>"
+ "http://lifehacker.com/index.xml<title>Lifehacker<description>something";
string[] test = new string[15];
myString = myString.Replace("", "#");
myString = myString.Replace("", "#");
test = myString.Split(Convert.ToChar("#"));

I want to extract substring and store it in an array from to , it repeats two times in my string. How to extract it?
|
|
|
|
|
You can doing it with using for loop.Check '<' in string array if array is not contain that than store that sting with ++

Dirty but seems to work.
string sFull = "this the is test for the true";
string sToSearch = "the";
int iFirst = sFull.IndexOf(sToSearch);
int iSecond = sFull.IndexOf(sToSearch, iFirst + sToSearch.Length);
string sText = sFull.Substring(iFirst + sToSearch.Length, iSecond - iFirst -sToSearch.Length);

Thats not a string, its called "Xml" and there is built in ability to read its node values.
Have a look at System.Xml.XmlDocument and System.Xml.XmlTextReader

I have a form that can optionally display several MDI children forms. I have a toolbar that when clicked, I'd like to make the child visible and bring it to the front. If the child is already visible but not in the front, I'd like to bring it to the front. Finally, if the child is visible and in the front I would like to hide the child until the button is pressed again.
I have no problem showing/hiding or bringing the form to the front, but I don't know how to determine which form is on top. Any ideas on how to do this?
Thanks

This is a feature I've seen with the picture control on VB, but could I do that with text boxes or buttons on C#?
I´m trying to change some properties of textboxes but I want to use iteration. For instance, I want to assign the for cycle counter's value to each textbox and display it. 1 for textbox1.text, 2 for textbox2.text and so on.
If anybody has another method to do this please tell me.
I hope made myself clear and excuse my english.
Regards
Ivan

You can create an array of pretty much any type (in your case text boxes).
Note: Pseudo Code
TextBox[] myTextBoxes = new TextBox[5]
for(int index = 0; index < myTextBoxes.Length; index++)
{
myTextBoxes[index] = new TextBox();
myTextBoxes[index].Text = String.Format("TextBox #{0}", index+1);
}

Additionally to what teejayem said: if you want to modify the textboxes of your form, then you can do this:
foreach(Control c in this.Controls)
{
if(c is TextBox)
((TextBox)c).Text = insert_your_text_here;
}

Hi there.
I have a XML file like this :

I want to search in it by LINQ.
I used this code
X_Element = XElement.Load(FileName);
var searchNodes = from nodes in X_Element.Descendants()
where Regex.IsMatch(nodes.Attribute("HREF").Value, "Mozilla", RegexOptions.IgnoreCase)
select nodes;
But there is no data in searchNodes
What's wrong with it ?
Thanks in advance

Hi
I have a custom control which encapsulates a dropdownlist and label.
when you select an item from the dropdownlist it should autopostback
and change the lable text. But postback (selectionchanged) event is
not working at all.
Here is my code.
protected override void RenderContents(HtmlTextWriter output)
{
this.buildControl(output);
}
private void buildControl(HtmlTextWriter output)
{
Table currencyConverterTable = new Table();
// add a label
// here I am adding a dropdownlist
dropdownlist currencySelector= new dropdownlist();
currencySelector.DataSource = mydatasource;
currencySelector.DataTextField = "CurrencyCode";
currencySelector.DataValueField = "id";
currencySelector.DataBind();
currencySelector.AutoPostBack = true;
currencySelector.SelectedIndexChanged += new
EventHandler(OnSelectedChanged);
// add this dropdownlist to the table
// now render it
currencyConverterTable.RenderControl(output);
}
Shouldn't OnSelectedChanged event be fired?
Thanks,
Toby

Is the BinaryWriter basically functions the same as the StreamWriter??? Can some give me a brief explanation on each? (believe me I did research, and 0% knowledge from what I have read)
|
|
|
|
|
StreamWriter is designed to write strings (essentially, you will use it to write text files).
BinaryWriter is used to write raw bytes to a file (say you were writing a wav file).

Seeking help with
(i) method/ c# code to remove every second item in a queue
I tried front.next = front.next.next but it this is removing only one second item just after the first but would like to remove every other second item/element through out the queue.
(ii) c# code for reversing a queue .
|
|
|
|
|
(ii)
A queue is a first in first out type right?
So take a queue that you want reversed and put it into a stack.
Then move the stack to a new queue.
This will reverse the queue.

How do I put all that into C# code?

This sounds like a homework problem. Even if someone here did it for you, you still wouldn't be able to do future (and harder!) problems.
Use an easy problem like this to develop your programming skills. Figure out the procedure you'd use to solve this with pen and paper. Then figure out how to implement this algorithm with C#.
