I have been asked to try and create a tool that will take an HTML table from a .html file and convert the table into an image.I am not sure how to approach this. I have tried several examples on the web, but can't seem to get any to work, like convert from base64 string into a byte array, then into a memory stream, then to image. I have also tried to use a webrequest, but cant seem to get that to work, either.

I have a column in my database that stores images that are links, when i populate them in a gridview on my asp.net page I want it to display the image as a link but when i did it i just get the text below.url...My goal is to have a list of the images and when a user clicks the image they will go to another page.
View 1 RepliesI am having a problem with submitting html from a textbox into a mysql table. I would believe this to be due to "special characters".
The code I am using is,
vb.net
Dim html = (sdata.Text.ToString)
Console.WriteLine(updateRecord("INSERT INTO course (tittle, length, begining, price, about, table) VALUES ('" & TextBox1.Text.ToString & "','" & TextBox2.Text.ToString & "','" & TextBox3.Text.ToString & "','" & TextBox4.Text.ToString & "','" & TextBox5.Text.ToString & "','" & html & "')"))
MsgBox("Success! You have Successfully created a new course, " & TextBox1.Text.ToString)
Me.Visible = False
The error I get is:
A first chance exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in MySql.Data.dll
I am using this code to parse an html file for image locations:
Dim htmlDoc As String = IO.File.ReadAllText(path, System.Text.Encoding.Default)
Dim Regex As New System.Text.RegularExpressions.Regex("img.*srcs*=s*(?:""(?<1>[^""]*)""|(?<1>S+))")
[Code].....
How would I change the regex string so that it leaves off everthing from the img to the src=, so that I'm just left with what's in between the quotes? Note that sometimes there is stuff between "img" and "src=" and sometimes there is not.

I've been programming in VB6 for years, I have decided to take the plunge into VB.net and C# 2010 but having a little problem understanding the big picture.In VB6 I could create user controls and save them as .ocx files, then use those .ocx's in other programs or on html pages. I am sure the same idea is present in VS 2010, I'm just not seeing it.Can anyone recommend a book or tutorial that will show me the big picture of all the aspects of the .net environment?

View 1 RepliesI 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)

View 5 RepliesI 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>

I created a function that creates a global temporary table to stage data from a excel sheet I need the table to persist for me to map the columns using a form. The table is still there when the code goes back to the sub that calls the function until I call the form where I do the mapping. I am trying to avoid create/drop table scenario with a perm stage table.How can I get this table to persist until the data gets loaded into the perm table?
View 8 RepliesI am working with a Vb.net 2005 application. On the application I have a Create table button which when clicked creates a table in Sql server with the code shown below;
Code: Private Sub BtnCrtTable_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnCrtTable.Click
[Code]...
This is really a pre-defined table and the data is already specified to be inserted to the table. However, my primarily task is to read a flat file which has the data and consider the first line as the column to be column names.
Therefore, initially I created an open dialogue to browse for the text file and store the path such as E:Datafile est.txt, in a TextBox1 visible at run time. Now the task is to change the above "create table" to read the txt file (column names are on the first line) and then create the table in the database.
I have a normal winform and I would like to know is there any possibility to generate a html page and to add a css file to the html page from the local folder.

</head>
<body>

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.
