I'm using the HtmlAgilityPack to extract data from a html document. I can get the data to display in console.Writeline however I need to get it into a DataGrid/DataTable so I can import it into SQL Server. For the life of me I can't figure out how to get it into the DataGrid.

I am using a string builder to set up an html table row by row so that it can be emailed. I currently gather my information from the database using a data reader and while dataReader.read, I use stringbuilder.Append to add each cell value to the table.The issue is that after about 200 rows, the html breaks and displays a cell value above the table in the email. I have tried changing the cell padding, but this was not successful.
View 2 RepliesI would like to print an HTML file that I am generating myself, but I want the pages to have the same table header at the start of each page. I think the best options to print an HTML file is the webbrowser control? but this won't give the table header at the start of each page (and I will have to contend with the ugly file://c:empfile.htm at the top of each page etc)

I have a html text file and I am trying to remove any HTML tags in tables, i.e. remove any HTML within THE <TABLE> and </TABLE> tags.
However, what's really weird is that the regex that I use, (?<=<table((?!</table).)*)<(?!/table)[^>]+>, works perfectly in PowerGREP or EditPad Pro, however, when applied in vb.NET (or Expresso) to the VERY SAME text, it does NOT work! I just use a simple replace method: newString = Regex.Replace(oldString, "(?<=<table((?!</table).)*)<(?!/table)[^>]+>", string.Empty, RegexOptions.IgnoreCase)?
Below is the example text:
texttexetext
<TABLE>
<TAG1>

I am trying to write a class to serialize/deserialize something as simple as:
<table border="1">

I just can't get it to serialize to this thing. I tried to generate the class using xsd but that produced a lot of garbage code and I really would like to maintain this by hand as it is easier than the monstrosity that xsd produced which didn't work anyway.

View 2 RepliesI'm wanting to extract a table on a regular basis from an HTML web page in to a listview control. Before I start the long winded manual process (which I'm sure I can do, finding strings etc). I was wondering if there was a built-in way with VB.NET?
View 6 RepliesI'm currently creating a HTML editor using a WebBrowser control and using IHTMLDocument2, but I'm currently having a problem that when I insert a table the user is unable to resize the table columns by dragging the border.
I was wondering whether anyone had done anything similar using IHTMLDocument2 and how I would be able to allow for the user to resize the tables like that. Or if anyone knows any good HTML editors that are written in VB.Net and are open source, unfortunately this is a requirement as I have to do some custom stuff for my customer.

My question is a combination of VB.Net creating html code..No Google links to pointless areticles in languages that are not VB.NET, please. If you cannot code it yourself, please don't reply because it's so annoying to ask a question then get pointless, timewasting links just so you can get your points score up.I have a table which has 3 columns - nothing special just simple but its's the row number I am having issues with. Will explain soon.There is a directory with jpg files in it and the number of jpg files increased yesterday by 67, today by 37. Because the picture files come with any filename I have created a Windows app that renames the new files taking the ending point of yesterdays number as the starting point for today..So, each row holds 3 jpg files therefore 67 jpg / 3 = rows (yesterday). First number today is 68. I type 68 into the app I created, enumberating & moving (renaming) the jpg ('hduyhdgu.jpg becomes 68.jpg, suhdos.jpg becomes 69.jpg and so on for each of the new jpgs in that directory. That is done by the simple FileInfo/DirectoryInfo classes. Whilst renaming the photos in numerical sequence it has to write the html in the following form: [code] My Questions are:
1) How to sort out the row numbers so they flow in groups of 3 correctly and not 70, 71, 72, 71, 72, 73, 74, 75..?
2) How to create the table in code that dynamically draws itself with 3 columns (200px each done by CSS) wide and enough rown to hold every jpg in that directory? So, if I moved 5000 jpgs in that directory tomorrow the code will loop through and create the html.
3) If creating the table dynamically as in Q2 above how would I fix the place to draw it? Placeholder? A div is easy (<div 'id="MyTable" runat="server"></div>. In code behind: MyTable.InnerText=.../MyTable.InnerHtml=...) but is it the best idea? [code]

again after a week of trying to figure out how to parse a HTML table I have yet to figure it out.Below is the Table I am trying to get the information out of.

The problem I am having is that It pulls out the 28,900 fine but I need to pull the rest of the information IE the 23,132 and the 170,000 and they will get placed into other Labels. Now they are not Static numbers they change all the time to higher or lower lumbers.
I am trying to update a database table from my datagrid using an event handler and ItemCommand. I manage to call the routine and everything is working fine except the text that is inserted into my database is empty. I managed to track this back to the text not being passed from my datagrids footer to the sql parameters. I tried using a string first and then passing that to the parameters but they were also empty. I am accessing the control using the following line.
sqlcmd.Parameters.Add("@GoodsDesc", SqlDbType.VarChar).Value = CType(e.Item.FindControl("txtGoodsDesc"), TextBox).Text
The control itself is defined using
<asp:TemplateColumn HeaderText="Goods Descriptions">
<ItemTemplate>
<asp:Label runat="server" ID="lblGoodsDesc" Text='<%# Eval("GoodsDesc")
[Code]....
It's like the text in the footer isnt being tied to the control before I call it.
