I just upgraded a project from VB 2008 to VB 2010. Before, the project did not use LINQ. I have started implementing it. So, I have updated the target framework from 2.0 to 3.5, and added a reference to System.Core, and imported the namespace System.LINQ to the entire project and also imported System.Data.LINQ into the form I'm working with (because it was not available in the list for Imported Namespaces in the references tab).
It's not throwing any errors now, but my IntelliSense is not working for LINQ stuff.
For example... I write this:
[CODE]....................
Then, if I type S. on the next line, the IntelliSense doesn't grab what it should for S (Only get Equals, GetHashCode, GetType, ReferenceEquals, and ToString, instead of the options I should get like Count, First, FirstOrDefault, etc...). If I Type S.First. then its the same thing, no IntelliSense that lists the available fields for S, just the standard options (Equals, GetHashCode, GetType, ReferenceEquals, and ToString). I should be seeing my column names in my table when I type S.FirstOrDefault.
So any ideas what is going on? When I type the code, for example, MessageBox.Show(S.FirstOrDefault.FirstName), it works perfectly. But it doesn't change the casing of the text (so it would read s.firstordefault.firstname) and no intellisense while doing it. But no errors. BTW - Everything works perfectly when creating a NEW VS 2010 application, it's just my projects upgraded from Visual Basic 2008 that have this issue.
I was just wondering how to extract or parse any particual tags (whichever I specify) from webpages. I know how to extract text and links from webpages, but I tried to use the same method from the following code for div tags, title tags etcetera and it doesn't seem to work:

View 2 RepliesHere 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.
I 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 RepliesIm 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?

All 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?

I have a .trx file (a unit test result file) which is just xml inside and I want to read the file compare a few of the tags and change them as necessary and save the file again.
I found that VB.NET has a few tools to help so the first thing I do is load the document into an xml document which seems to work fine but I can't access any of the data I need. Right now I'm trying to access the attributes of the counters tag and change them after rerunning some of the tests.
this loads the file:
Dim Doc As XmlDocument = New XmlDocument
Doc.load("testFile.trx")

View 2 RepliesI 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.

I am trying to create an application to make self-extracting Exe's in Visual Studio 2010 Express. I would like to have a box in which files can be dropped into, then when you click "Compile" it will compress all files dropped into the box along with 3 others I must have delivered to this self-extracting exe. When the newly created exe is run, it will launch "Install.exe". I know there are other items out there to build the self-extracting exe's. I would however like to make my own that always delivers these 3 specific files along with whatever is dropped into the application.

Ok I got a variable named Accounts and stores the user accounts. They are seperated like this
Account|Pass|Admin&Account|Pass|Admin
As you can see after admin there is a symbol (the &) meaning that before the & its an account and after it its another. In other words its like this
Account|Pass|Admin
Account|Pass|Admin
so how can I make a loop to count how many & there is in the Variable named Accounts?
