I would like to populate a <p id="para1"></p> html tag from the codebehind page in VB. I need to read text from a text file that will be periodically uploaded from a user and display it on the aspx page in specific paragraphs.
View 2 RepliesRight now, I am working on taking a self-updating excel sheet and building small html blocks from the sheet which will fit into a JQuery list sorter and image viewer (tags and tags ). The problem I am running into is that by placing the code onto the page in a literal the html is never placed on the page, it is generated on the fly, thus the JQuery handler can not hook the tags and the sorter does not function. I know there is a way to add variables from the code behind with <%=var%>, but I need to add a large number of variables that will change as the excel sheet updates, which is why I am using a code behind function to generate a glob of instead of rewriting it constantly.Here is my current Code behind function that generates and inserts into literals:
Dim count As Integer
count = ds.Tables(0).Rows.Count
Dim tags As String

Is there a way to write text between html tags?like <textarea>TEXT HERE
View 7 RepliesI'm using Telerik RadControls, in my codebehind I have the following function, a portion of which adds buttons to the footer.
[Code]...
I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

Need a bit of help with HTML Agility Pack!Basically I want to grab plain-text withing the body node of the HTML. So far I have tried this in vb.net and it fails to return the innertext meaning no change is seen, well atleast from what I can see.
Dim htmldoc As HtmlDocument = New HtmlDocument
htmldoc.LoadHtml(html)
Dim paragraph As HtmlNodeCollection = htmldoc.DocumentNode.SelectNodes("//body")

I have tried this:
Return htmldoc.DocumentNode.InnerText
But still no luck!
I am trying to build my own website and realized that it would be a big help to also create my own vb program to enable me to embed tags with simple clicks of buttons. I am having trouble getting my vb code to be compatible with html code (I keep getting vb syntax errors).
Here is what I've tried:
<strong>'Inside of a button:Textbox1.text = "<html tag example></html tag example>"</strong>
I have a trouble making this code work. When executed, it just creates a correct (with the correct name) file with the extension .txt but the the actual text inside .
Imports System.IO

Public mytext As String

What is the best way to write data from a hierarchical set of objects to a file? The highest order parent has 1000's of children all with children (DOM style). Trying to traverse the tree and creating one big string which is then written to a file is throwing an out-of-memory exception while creating the string.
Details I've created a set of classes that make up an HTML document. There was control that I needed that the pre-packaged HtmlElement and HtmlDocument didn't give. The Document Object Model is maintained throughout, with some similar methods and properties and such. I'm using the custom classes to create a very large HTML document. When I say large, I mean on the order of over 2000 printed pages. It's doubtful that they will all be printed, but some will be.
My base HTMLElement object, from which all other objects are derived, contains an OuterHTML property which, as expected, gets the full HTML of the calling object and the HTML of all child elements. After the code which generates the report runs, I have my HTMLDocument object containing the entire report which needs to be written to a file. Here is where I keep running into problems.
If I call OuterHTML on the HTMLDocument object, I get an out of memory exception.
Other reports have saved fine, but this is by far the largest report I've thrown at my HTMLElement object. My assumption is that the property call is generating too much text.
I am basically just creating a new .HTML file, opening it for reading, and writing in all of the text. Like:
File.WriteAllText(FileName, HtmlDoc.OuterHTML)
I have following text box control on my web page.[code]...
now i want to give my users the functionality to make their text bold or appear in different colors by using html tags when they enter text in this textbox.
then i insert this text in sql server 2005 database table. but whenever i use any html tag like <b> it gives me following error.
A potentially dangerous Request.Form value was detected from the client (txtTitle="<b>jjj</b>").
I have a block of HTML which I want to write to a file. It contains about 30 lines and it's difficult to escape all the double-quotes in individual WriteLine statements. In PERL, I can do something like the following to write inline HTML and print everything upto <<OUTFILE to outfile as-is, is that possible in VB .Net 2008?
print <OUTFILE
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML><HEAD><TITLE>GSC Signature</TITLE>
<META content="text/html; charset=windows-1252" http-equiv=Content-Type>
<META name=GENERATOR content="MSHTML 9.00.7930.16406"></HEAD>
<BODY><<OUTFILE
I could save the HTML in a template file and copy it into a new file each time, but that's not very flexible.
I am trying to obtain a file path that users manually enter on a web page, and then write it to the web.config file.

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>
[Code]...
Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?

I've got a program which displays data in a listbox in five columns. All are separated using one or more ControlChars.Tab. I want to write these columns to a text file, however, when I do, my columns lose their alignment. I can change alignment so that it displays nicely in text file, but then it is off in list box. Is there a way to get what I see in my listbox to display the same way in a text file - maybe a different way of separating my columns (not using ControlChars.Tab)?
