Hi,
I am developing a webcrawler/webspider in C#.Net 2005, I am extracting text from web pages through the code below. But the problem is that it only extract text from html pages because asp.net pages does not contain headers like …. So how I extract text from asp.net & php pages.
Code for extracting text from html web pages
S is string which contains the webpage
MatchCollection mPage = Regex.Matches(s, @"((|||||)\s*.+\s*(|||||))", RegexOptions.IgnoreCase);
foreach (Match mP in mPage)
{
StreamWriter i = new StreamWriter(@"C:\WebSpider\index.txt", true);
i.Write(mP.Groups[0].Value.ToString() +"\t"+ u +"\n");
i.Close();

Hi
In my Web Form, I have this code:
<code><HEAD>
<title id="title" runat="server"></title>
</Head></code>
Then in the code-behind file, I set the title of the page dynamically.
My problem is that sometimes, my web form deletes <b>runat="server"</b> property from the <title> tag automatically. Because it deletes the <b>runat </b>property, my page stops working. I manually have to add <b>runat="server"</b> into the <title> again.
So please tell how I can solve this problem.
Thanks

Just do this in the code behind:
<br />
this.Page.Title = "Your Title Here";<br />
|
|
|
|
|
Or you could do this:
<head>
<title><%= pageTitle %></title>
<head>
and in your codebehind define pageTitle as protected and assign it in the Page_Load event: pageTitle = "the title of my page";

Any one please help me to add context menu to a table row. And the menu should not come when right clicking other parts of the page.

Why is it necessary to implement try catches in your source code when there is already page-level and application-level error handling? To me it sounds a bit redundant.
In the page-level and application-level error handling I log the errors (and InnerExceptions) in the DB, email and the event logger.
Thanks

It is good practice to handle exceptions as close to the source as possible. This gives you the opportunity to handle the exception in an intelligent way and resume work if appropriate. If you wait to catch it at the page or applicaiton level it may be too late.

Agreed. As with anything the trick is know when and how to use the tools you have. What I meant was not to just bubble the exception back up the call stack when it can be handled at the source, especially in the case of a class library. If I can recover from an exception in my library I don't want to make it the responsibility of the calling application.

Lets say if you accessing a webservice to retrieve party information and that causes an exception what is the most logical thing to do once it is caught? Im logging them at page and application level. Do I just revert the customer back to that same page where the error occurred and lot it or do I transfer the user back to the homepage and log it. Excuse my ignorance Im a novice with regard to error handling. Thank you

How you handle it depends on the application. Without know how your app is desinged to function I would say to return the user to the page with some message indicating what has happened, i.e "Invalid data", "No record found", etc. Give them a chance to correct any entries. If there is nothing for them to correct, then possibly it would be appropriate to return the to the home page.

With the try/catch exception handling you can provide 'alternate' solutions to any problem that you anticipate in advance... for example, if the db connection fails, or if the page dosn't load, etc. you can do something else for the user so that they don't see some error page or message... my 2-cents

instead of loading into an xmldoc ,
append it to a string and write it to response like
Response.Write(string)
you can handle the responsetext
as
responsetext[0]

VS.Net has detected that the web server is running asp.net version 1.0.The web application you are creating or opening can be configured to be compliant with asp.net 1.0.
However, the application will not be able to use new features from asp.net 1.1.
