HTML Table Displays Random Cell Values Outside Of Table
Sep 23, 2009
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.

I have to pull out particular fields from cells in an HTML table. Using Firebug I was able to get the exact XPath to the cells I need (unfortunately, the cells don't have an id tag). I thought I could use DocumentNode.SelectSingleNode and pass in that path, but it doesn't seem to be working right. What am I doing wrong? Or is there a better approach to this than how I am doing it? Unfortunately, I have no experience with XPath so this is turning out harder than I expected it to be. Here's what I have so far (I know the HTML is particuarly messy, but that's not in my control to change):[code]

I 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>

Data table information: Data Source = Login.accdb, Data table = LoginTable, Connection = LoginCn. I use visual basic 2010. So how do I do this?

I'm attempting to copy cells, one at a time, from an Excel 2003 (or 2007) spreadsheet to a Word 2003 (or 2007) table. I'd like the code to be version-agnostic, and so am using late binding. The formatting of the contents of the Excel cell, such as color, underline, strike-through, needs to be preserved. My approach is to use a Word doc as a template. It has a table at the top which I can copy to the end of the doc, add rows as needed, and fill in the word table cells with the data from the excel spreadsheet. Unfortunately, all the formatting disappears. All I get is the text itself.

I have a data table whose one column is related to a column of another table. I have a listbox in a form which shows a column (which is sorted by another column value by ORDER clause) of the parent table and other columns are in textboxes. The child table is represented by a datagrid. When I add a new item in parent table and click save, the newly created item is listed at the bottom of the listbox violating my ORDER clause. When I wrote some codes to fill data again after updating, it shows an error message[code]...

As a bonus to the project I'm currently working on, the people would like it if I could change the background color of individual table cells depending on what their value is. So in the RadGrid_ItemDataBound event handler I have, I'm trying to set the BackColor of the cell if the cell's text equals a certain value from a dataset in my database. My current code is like so:

What I need to do is if the table has a row then copy the text out of a cell to a radiobutton. The text I have so far is:
If EXISTS(ds.Tables("DogBasic").Rows(0).Item("DogName")) Then
RBDogName1T.Text = ds.Tables("DogBasic").Rows(0).Item("DogName").ToString
Else
RBDogName1T.Text = "Add Dog"
End If

But I get an error:
Error 1 'Exists' is not declared. It may be inaccessible due to its protection level.

I'm new to VB and am trying to create something that will change specific words within a DB entry to a random word from a table. My goal is to change swear words to a random word in a separate table (like darn, dang, waterstopper, etc.) So far I have an "Input" table with the text I need to change and a "SwearRep" table with a list of words I need to replace in col "WBad" and their replacements in "WGood".

How to select one cell and mulitple cells in a table using the webbrowser control. E.g. If the web page (local) that I'm viewing in the webbrowser control has tables present in it. When I click on a cell in the table I want to be able to edit the attributes of the cell like adding an align or a class attribute. I think this is possible without using mshtml which I'm trying to avoid as I can't find much user friendly documentation on it.
The text in the webbrowsercontrol is loaded with the foll:
WebBrowser1.DocumentText = Form1.RichTextBox1.Text
So I am guessing that I need to be able to detect when a cell is selected (<td></td> tag etc) or clicked on and then from that point I can edit the attributes of that specific cell (<td class="jimmy"></td> tag etc).

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

<td>row 1, cell 1</td>
[Code]....
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.
