How To Extract Text From Webpage
Apr 23, 2012
I am working on a project just for fun in my spare time and would like to know how to extract certain text from a webpage. For example: One of the tools I wish to have is a translator and I wish to use google translate set on Detect language to English. What I wish to extract is the translated text into the form or a msgbox.

I am trying to build a VB.NET 2005 windows app which gets cars info from a webpage(webapplication) that has a username and password.
I was able to programmatically login to this webpage(by automatically populating the input boxes using webbrowser control) And after I logged in, I could view the cars data in browser and I did "View Source" but the cars data (such as car model, brand, color etc..) were not viewable in the page source code. So how can I read these data with my application?

I have the following code to open a webpage:
Dim IE As Object
Dim x As Integer
Dim c As Variant
[code]....
The page that opens is in xml and in that xml there is the "page_count" that I need to pick out so I can tell my macro when to stop looping. I have dimmed it as "c" in the code above. Following is the XML.
<search>
<total_items>360</total_items>
<page_size>100</page_size>
<page_count>4</page_count>
Somehow I need c = "4", which is the "page_count". Does anyone know how I can pick out the "4" from the xml on my page?

Basically I am building a webcrawler and in order to do so
I have to extract the page source of a webpage which I can do so like this:
CODE:
The above code works fine on most of the websites I have tried to extract page source from but for some reason it is failing to extract the html contents of few websites like these where the message posted by a user is nowhere to be seen? The webpage in question is this: [URL]
Is there something I have missed or is it due to forum protection etc which is preventing the vb application from extracting the whole page source?

Is it possible to take certain text from a web page and paste it into a Rich Text Box in Visual Basic? I'm going to use this http://google.com/complete/search?output=toolbar&q=mlb to generate a bunch of keywords and I want to highlight just the keyword paste it into the Rich Text Box. How can I do this? Also a better way to describe this is almost scraping the keywords through all that code and putting them into the richtextbox.

To simplify what I am trying to do, let's say I have a text file with only one line of data.
The data in this case is color info for one pixel:
Color [A=255, R=255, G=200, B=128]
What I am trying to do is read the text file and extract the hex color info and save them to their own variable.
So once the code has run, these should be the contents of the three variables.
RedData = 255
GreenData = 200
BlueData = 128
I have managed to get something to work but I know the code is terrible and is incredibly slow when I try to run through hundreds of lines in a text file.
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim PixelData As String
[Code].....
