what i am trying to do is extract information beween two tags in some html from the source of a website. The contents of the text between the two tags will always be different. the code i currently have is;
The idea is that I have certain values stored in textboxes/listboxes and thus can I store the information in a spread sheet. And if I change the value in the spreadsheet can it also change the value in the application? I had one idea which was to make both store data in a txt file and read from that, but I'm not quite sure how to do that either.
I am new here and really excited to see the huge resources on this forum for vb.net. I have just started my learning of vb8 and need to create some basic applications for my personal use.I need to develop an application that can extract data from a html table and store that data into Access database. I have learned to create web browser on Visual Studio 2008. Below is the link from which I need to extract data and store into a database
I had been doing a split function after the ":" but, that doesn't turn out so good once you add in file paths. I have turned to trying to grab the first ":" from the left using the "InStr" function which returns the char integer. I need a way to grab all the information on that line after the first ":".
how to parse and extract specific elements out of a JSON that I obtain from a web source. Using Visual Studio 2010 and VB. I can get the JSON but I haven't been able to find any examples or tutorials regarding parsing the data, locating specific elements and their associated data.
I have a parse from Wikipedia saved in a text file in the following form: The town itself is situated to the south-east of the rock, and overlooks the Palaia Monemvasia bay. A small hamlet with about 10 houses lies to the northwest.The founding of the town and fortress of Monemvassia most probably occurred in the 6th century AD. The town was founded in 583 by people seeking refuge from the [[Slavic peoples|Slavic]] and the [[Eurasian Avars|Avaric]] invasion of Greece. From the 10th century AD, the town developed into an important trade and maritime centre. The fortress withstood the [[Arab]] and [[Normans|Norman]] invasions and conquests in 1147. Cornfields that fed up to 30 men were grown inside the fortress.What I need to do is to extract specific texts from the parse given the header names. For example, if I type in a textbot Geography I need ONLY the geography text returned.
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()) [Code] .....

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).

<strong>'Inside of a button:Textbox1.text = "<html tag example></html tag example>"</strong>
I know how to extract an entire page source into VB.NET, but once I do that how do I make VB.NET search the text and return a specific vlaue that is not constant?
Not sure if this is possible at all. I was hoping somebody could help point me in the right direction. Right now im not quite sure what to search for or what this would be called. Basicly I was wondering if it is possible to design a application in vb.net 2008 that could search a website for specific information.

I have an email account that receives various requests to get free materials, for different items. These emails will usually contain name, item, quantity of item, address, state, zip. What makes it difficult is that all the emails are different, unstructured, and the data is usually buried in the emails, i.e. a forwarded email.I want a way to get all the information and parse it into a ms sql database.I know there are products that would work really well like url... but at work we can't afford this.I was thinking of creating a webservice that would input mail data posted from a third party site like cloudmail.com into a secondary website and then maybe creating a ruby script that would crawl the messages and extract addresses, etc. Anyone know of a good, simple alternative, a custom script in ruby, php, vb.net or possibly an open source solution?

But it only showed be how to go to the first tags. In this xml, it is in a few tags, (<MediaInfo> <File> and <Track>) I don't know how to go past those tags to get to the tags that I want to get to, plus, how would it work when there is a few things that have <Track> as a tag?

How can I add my HTML code to my VB.NET application. I know about making a .html file and calling it from WebBrowser1.Navigate, but the problem with that is, I don't want to have a separate file. I would like everything to be embedded into my vb.net source.

I have connection to the Access database in my Visual Studio 2008 solution. Now the problem I am having is when I enter the information on to the form how is it suppose to transmit it to Access? I am sorry to be a pest, but I did not want to take this class eventhough it is required. I only have a few weeks left of class. I have tried looking at a lot of tutorials but it seems to be just repeating the same thing over and over. I wish there was a Visual Basic for dummies that can be accessed on line
