I'm scraping a page from a remote site. I have the correct HTML and it is below. However, I need to display only the top 3 new stories. Using C# how can I loop through the HMTL on the page to do this? Here is the HTML that I have scraped from the screen and am currently display on the page:
<table
style="width:100%;">

Is there a way to save html content of an aspx page in the pageload part of the cs file and have it loaded again on postback?
Maybe using a streamreader to save it then have the streamreader write the content back in?
I have a page with is basically a few Gridviews that I want to email to some users. The Gridviews are connected to sqldatacontrols. I create the select statements in the code behind. This all works fine.
To email the page I read the page into a streamreader and then creates an email and sends it. So when I get the email the Gridviews show no data.
I stepped through my code and found that the issue is with a variable. The Select statement has a few parameters one of which comes from a profile variable. When the page is read the profile variable is empty. I tried it as a session variable and that fails as well so my question is if I cannot use profile variables or session variables what other way is there to save this data?
In VB I can place module level variables so that say when a form loaded and I wanted to save a variable I would load the module variable which made it available to any form in the project but I assume that I cannot do the same in VB.net asp.Net? On the first page load the variable is available I just have to figure out a way to save it to pull out again when the page posts back.
I wish I could go all the elements of an ASP.Net page (HTML elements) and manipulate its text property / value. How could I do that?
I've been checking, and the property this.Page.Form.Controls apparently gets all the elements, but I would only page elements that caught the event.
I'll put an example of code that I'm currently studying and trying adpater for my needs.

How can I loop through table and row that have an attribute id or name to get inner text in deep down in each td cell? I work on asp.net, c#, and the newest html agility package.
An html file have several tables. One of them has an attribute id=main-part. In that identified table, there are many rows. Some of those rows have same attribute name=display. In those named rows, there are many columns which I have to extract text from. Something like this:
<body>
<table>
</table>

I have a question about asp.net
I have this table with checkbox for each row:
[URL]
table code inside the ASPX page:
[URL]
So I'm trying to implement the delete selected button.. How exactly do i point to the specific checkbox for a particular row from codebehind when all 3 have the same name chkSelected? I know how to do it with a gridview, but not quite sure how if we do it with a for loop..
Can I do something like this inside btnDelete_Click?

I'm trying to read an html but it's only reading the first 1169 characters? And when I open the source code it's huge!
here is the html I'm trying to read http://mesowest.utah.edu/cgi-bin/dro...graph=0&past=0. If i enter in another website it reads 23,000 characters.
Code:

I am calling a RESTful web service in the back-end of some ASP.NET pages.
I am using ASP.NET asynchronous pages, so under the hood I am using the methods:
HttpWebRequest BeginGetResponse() and
HttpWebRequest EndGetResponse()
The response string in my case is always a JSON string. I use the following code to read the entire string:
using (StreamReader sr = new StreamReader(myHttpWebResponse.GetResponseStream()))
{
myObject.JSONData = sr.ReadToEnd();
}
Is this method OK in terms of scalability? I have seen other code samples that instead retrieve the response data in blocks using Read(). My primary goal is scalability, so this back-end call can be made across many concurrent page hits.

I need to read a file on a server into a textbox. I did a test on my local PC, to make sure it works the same in a web app as it does on a desktop app.
The data appears to read just fine, but it doesn't display properly. The test file in the screenshot below, shows how the data should be displayed. When using a desktop app, the data displays just like this.
But on the web app, I get this:
Although the TextBox appears to be MultiLine, it only displays the data in the middle of the box and as one line. Am I missing something?
Im stuck with declaring a string which is in a loop within another loop.
Dim CompanyDetails As String = ""
Dim CompanyRow As DataRow
For Each CompanyRow In newdt.Rows
CompanyDetails += CompanyRow(1) & " " & CompanyRow(0) & "<br/>"...
How can I get this to see the GetInfo as declared..... since its in a loop within a loop?

View 3 RepliesI have an issue with a Loop that doesn't actually loop. I've posted a simplified version of my code below. Basically, using the NPOI excel library, I have an excel file with data on the first and second sheet, so I need to do a loop to get through both sheets. Below is what I have done so far, however this only works through the first sheet and then exits. It fails to increment the variable w. As you can see, there are other loops implemented in this code which function fine so I don't get it.It's been a very long day and perhaps I'm missing something very simple. I could have it placed wrong or something. If anyone else can spot what I might be doing wrong I'd be very grateful :)
