.net - VB 2008 - Extracting Data From Website?
Oct 20, 2009All I've been able to do is create the form. We have to get information off of a website and load certain information back into the textboxes on our form.
Assignment 6 - Text Parsing Many applications require you to extract information from a block of text. We will be using this heavily in the project. This project is designed to give you some practice extracting information out of text files. You will need to open up a file, search the file for some specific content, and then copy that content and place it on screen.
Go to Jobs.com and select a state that starts with the same letter as your last name (if there is no state that starts with the same letter, use the second letter, then the third letter, etc.). For example if my name was 'John Byway', since there was no B or Y, I would pick a state starting with W - either Washington, West Virginia, Wisconsin, or Wyoming.
The idea is you want to extract all the jobs information out of the page. We want to put the jobs names in a combo box, so the use can pick any of the jobs. Ideally, this would also show the information about each job. You don't need to do that. However, you do need to extract the information and put it on the screen (When you load the next job, the old job information will be lost, and you will be left with the information about the last job loaded)
Tasks
1. Go to the above address, view the source in the browser, copy and paste it into a text file. You do not need to access the Source of the web page within your application.(in IE go to View / Source; In FireFox go to View / Page Source)
3. Extract each job title and place the name in the Combo box.
4. Find and extract the following fields. Note, some jobs may not list all of these. In that case, get as many as are presented.
a. Date
b. Title of job
c. Company
d. Location
[code].....
Indicate on screen how many jobs you found. Note, you only need to look on the first page of jobs?
VS 2010 - Extracting Information From Website
Dec 20, 2010I want to extract some information from a web site (Bloomberg). This side has a search textbox with a onKeyUp event that, as far as I can understand, uses AJAX to create a table. Is it possible to insert some text in the textbox and then get the table created with AJAX? Given the source code of the page with the tabled already AJAXed (If you understand what I want to say here), I can easily retrieve the table. I just need to get the source code with the table already on it.

Feb 3, 2010My university has a website that students can use to check stuff like their lesson schedules, latest grades, exam times, etc. Just general information about you and your study (after you have logged in of course).For interested, this is the website (not much use without a login obviously, but still): [URL]I have been thinking lately that it would be nice to have a desktop application that could give me the same information. However, I have absolutely no idea how that would work, and whether or not it is even possible. I mean, technically it should be possible for me to get the information (how else does the website get it) provided it is not secured (even when using the correct login details). I am sure the website communicates with a database somewhere. Does that mean I could theoretically also communicate with the database (probably: read from it only, not write) for example by executing queries?If that is possible, how do I figure out which queries to use for the different pieces of information? Obviously I don't know the details of the database so I can't just send a random query and expect it to work...

Extracting Data From Database
Nov 7, 2010Here is what I did.
1. Went to data source window and clicked "add new data connection"
2. Choose Data Base clicked next
3. Clicked Create Typed UserInformation as the name
4. Next.... Under Data set name I typed UserInformation again
Does naming the database and the data set the same cause problems?
5. Created New Table called users for UserInformation Database.
6. I added the following Columns: FirstName, LastName, Address, and Phone
7. Edited the table to add a couple of people. Tom/Franks/108 blah street/5555555 and Bill/West/109 blah street/5555555.
8. I also reconfigured the data connection in the data source window to show the users table.
I have four labels on my form, a text box, and a button.
I want to be able to search the database by last name for what the user typed into the textbox when they click the button.
I know this is probably easy for all of you but I am still trying to get used to using databases.
Extracting Data From MS Exchange?
Mar 19, 2010I need to convert a VB6 application into VB.Net Windows application. The program pulls data from MS Exchange (UserID, firstname, lastname, etc - not the emails themselves) and places it in a .txt file. The code has been converted, but the program does not work. When the application is run, the .txt file is created, but is blank and I get a pop-up that shows the following, "trying to access email in outlook do you want to allow this?". The popup box is gone in an instant and when I try to click on yes, it does nothing. I always have to end the program as it is non-responsive.
View 14 RepliesExtracting Data From PDF Files?
Jan 3, 2006Im trying to extract predominately table data from a PDF file, however, I would also like the option to extract image files (such as graphs, etc) as well.Is it possible to extract data from PDF files using a VB.Net application? Im trying to get this process as automated as possible, so Im trying not to use 3rd party applications such as pdf file convertors or in-line pdf readers.
Are there any free, or relatively cheap PDF data capture API's/code snipets that I can use to import data from a PDF file? Another option is to export PDF data/images into an excel spreadsheet. Is there a .Net tool that will allow this?

Extracting Data From CSV File Into Searchable Structure?
