how i can read text or HTML from a website opened in IE?
This is the code i'm trying to use:
For Each ie As InternetExplorer In New ShellWindowsClass()
HTML = ie. ???
Next
I want to read the HTML code of the page into a string.
Eventually, I'm going to want/need the program I am creating to either:
A. Access the MySQL database from my website.
Or.
B. 'Load' a PHP page, and grab the contents off of it. [URL]Are these options avaiable in VB.NET ?
The projects program is designed to open files output by another program, allow the user to edit the files content, then send the file to a specific bookmark within a word template. Unfortunately most of the output files by the 'other program' are html format.Question Is there a way to strip out HTML from the file when it has opened in my text area within the program? I found one or two online guides but haven't managed to get them working.

View 11 RepliesI need to create a VB.net app that automatically reads a html table. It should connect to a web address (eg "[URL]") and read it. I'll be happy if I could just get the full HTML. I was able to use this code to get the HTML of a regular website:
Dim strReply As String = "NULL"
Dim objHttpRequest As HttpWebRequest
Dim objHttpResponse As HttpWebResponse
objHttpRequest = HttpWebRequest.Create("[URL]")
objHttpResponse = objHttpRequest.GetResponse
Dim objStrmReader As New StreamReader(objHttpResponse.GetResponseStream)
strReply = objStrmReader.ReadToEnd()
This code sample will give me the HTML for the website [URL]. However it will not work with the website I want (eg "[URL]"), because when you access it via regular browser it will popup a browser dialog asking for credentials (user / pass). So when I run the code above for it, I'll get the exception:
The remote server returned an error: (407) Proxy Authentication Required.
How do I set this up to use the credentials, before retrieving the HTML? This is actually my first web-related app.
I need to read a csv file but it's in a website, exemple: http://www.test.com/test.csv

I need to display the MinAH price and the name of the item listed in the table. If possible, I would also like to make a listbox of all the servers/realms in World Of Warcraft, giving the user the ability to change the realm that they want from the list because the prices will be different. Another thing would be a specific item instead of the ones already listed in the initial table (see link if you don't understand). You can search items on the website, I'm not sure how I could incorporate this so the user can select a specific item.

I have a website that divided into 4 frames. I'm trying to create an application that will constantly run on my PC as a task looking for certain text in the HTML in a frame.When it finds the text it would alert the user by presenting a pop-up message. This is basically a monitoring website that checking network nodes. Instead of staring at the screen looking for critical messages I would like to be notified when there is an alert.

I am trying to extract everything between the body part as I am building a forum crawler
and since all the user posts are between the <body></body> I have chosen to experiment
with Regex. So far I have coded the following but sort of stuck on how to output the result say in a textbox? Also I am not sure if the body part of the regex is correct.
Dim URL As String = Textbox1.Text
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create("URL")
Dim response As System.Net.HttpWebResponse = request.GetResponse
Dim streamReader As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream())

So, in this program I added 2 necessary login codes let's say, first a code that I will provide and then the username and password from my website. I implemented both ways, the first one worked perfectly, however, the second one is giving me some problems, my idea for that control was not using a database of users, that was going to be too complicated for a 14 year old guy, so I decided to take the source code for my website and I took a fragment, the boxes for the login, username, password, forgot your password, remember me and some other boxes, great, that worked perfectly, I uploaded the HTML modified document to my website's files and linked it to the URL of the webbrowser control in one new form, good, it's working, but I wanted a simple condition that works for this function "When the webbrowser loads the success website, hide me and show the past login form, when this one shows the failed login, popup a messagebox that says the error.". I have been looking for that simple condition for a long time. I am using Visual Basic 2010 Express Edition.

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 multilingual company website (Visual Studio / VB / ASP.NET 4.0), and when, on the homepage, you click a flag, the text changes to that language and stays with you the entire session, after I made a class, BasePage.vb. Everything works great, but the URL never changes .... clients.aspx remains clients.aspx although the text DOES switch to Dutch.
It's been recommended by @Aritstos to make it so it looks like clients.aspx?lang=nl as opposed to just clients.aspx in another language.
Currently, my asp homepage hyperlinks that work look like this:
<asp:LinkButton ID="LinkButton7" runat="server"
CommandArgument="nl" OnClick="RequestLanguageChange_Click"
class="flagbutton">

I need to parse a web page for blocks that contain open trouble tickets. The web page display several unresolved tickets and each one is inside a html divison labeled "issue-status". I've written the following code which does find the blocks, but when I try to parse its children to get its element fields (date opened, person requesting, history...) it instead pulls every element from the web page, not just the children.Is there a way to just parse the sub-fields under a particular DIV?
