I have the following xml:
<resume>
<details>
<resumeName>Jassim</resumeName>
</details>
</resume>
i am using this code to read the resumeName:
string resumeNameValue = doc.GetElementsByTagName("resumeName")[0].InnerText;
is it possible to have it like ["details"] instead of [0] SO i will also refer to it by name instead of id?

You can use XPath like this:
string resumeNameValue = doc.SelectSingleNode("/resume/details/resumeName").InnerText;

Hi All,
Can someone help me.
I have made an application (a kind of texteditor) in VS2008. Now will I count the words is the textbox. It works with the splitfunction. But can anyone help me with this becaus I don't want you use the split function.
I am a beginner with C# and I want to learn how the splitfuntion works. I know that is works with the if-else statement. But How???
Kind regards

Why?
But, yes, I wouldn't split a string just to count the number of words it contains.

You can use the IndexOf method inside a for loop to count all the spaces contained in the string.
Or, you can write a RegEx that matches a word and count the number of matches (EDIT: beaten by OriginalGriff on this one  ).

and how many words is that? 5 according to Regex? 4 when splitting by white-space? 0 according to Webster?

Smells like homework to me. You only get these kinds of requirements when an instructor hands out assignments.
In any case, since you seem incapable of figuring this out on your own...
Just iterate through each character of the string, and wehenever you encounter a space (or a tab), increment a counter. At the end of the loop, add 1 to the counter, and that's how many words are in your string..45 ACP - because shooting twice is just silly

Unless the string is empty, only whitespace, has multiple whitespace characters in a row (e.g., "\r\n"), or contains leading/trailing whitespace.

I have a C# 3.5 Windows form application that uses the webbrowser control.
This control is used to navigate through a website, where I have a parsing engine that pulls data off the site and stores it in a file. The customer navigates to the site, presses the "record" button and the parsting starts.
The parser is triggered by the DocumentComplete event. This works very well, but I have seen that this event sometimes does not fire. The customer has to navigate through 500 pages and by the time they get to page 500, we found that we are missing maybe 5-6 of the pages.
We have traced the problem to be that the documentcomplete event is not firing all the time. My debug code indicates that the navigating and havigated events have fired correctly, but not the document complete.
At the end of the 500 page run, I have 500 navigating events, 500 navigated events and a variable number of documentcompelte events, ranging from 490-495. We have not traced it to any single page, but are unable to figure out what is causing this. We even added a sound that beeps when the page loads and have found pages that load in the browser and are viewable, but the sound does not play because the event didn't fire. Any thoughts what might be causing this?

It could very easily be the server that caused the problem. It's not guaranteed that you will get a DocumentCompleted for every nagivation. You're only recourse is to put a timer in there and if the page does not complete within, say 1 minute, retry the navigation.

Dave,
Thank you for the reply. Your recommendation makes sense. However, I was unaware that I am not guaranteed a DocumentCompleted event for each successful navigation. What would couse the DocumentCompelted not to fire?
The strange thing is, I can see the page in the browser and I can interact with it, so the page has loaded (or so it seems), but again no DocumentCompleted event.
Can you elaborate on when I can expect the event to fire and when not to?
thanks for the reply.

The server not sending a complete document or a missing HTML closing tag.

You could always fire your own event when you get a response back from the server..45 ACP - because shooting twice is just silly

For debugging purposes, you could try the following:
1. get the target URL from the Navigating event;
2. cancel the Navigation;
3. use your own code to fetch the page text, using HttpWebRequest and HttpWebResponse;
4. when the response is in, stuff the result into WebBrowser.DocumentText
You can now add logging/debugging stuff to step 3 until you discover what is going on; then work from there.
BTW: I am not suggesting you do this as the final solution! A timeout/retry scheme seems fine, the one problem with it is you'll never know what exactly is going wrong.

I like the idea of digging in to this deeper. I need to figure out what is causing this event not to fire and this seems like a very good way to help isolate it. Thank you.

Thank you all for the input. By using a combination of solutions recommended, I was able to detect the condition. After the navigated event fires, I set a timer and if the documentcomplete event does not fire in the specified time, I can immediately detect the issue and alert the user. This is an acceptible work around for now. I will dig more in to the issue later.
Thank you all for the advice.

If the program isn't doing what you intended, the problem is in the code..45 ACP - because shooting twice is just silly

There is no such thing. You have a code problem somewhere.
What are you doing in Form Load? Do you have any other process that is consuming the CPU in that form? Does the app still respond on other forms? What does the code look like?
