Add Each Href To A ListBox If It Has A Specific Class?
Jun 24, 2010Ive just started vb.net programming, and Im trying to make an application to collect twitter usernames and addresses - this is how all the links look:
<a target="_blank" href="http:twitter.com/USERNAME" class="twtr-user">USERNAME</a>
So in the tag of <a>, for each element, there is a class called "twtr-user" So basically, is there a way to go through the webpage and add each username and address to a listbox? This is what Ive come up with so far:
For Each temp As HtmlElement In wb.document.Links
Dim str As String
str = temp.GetAttribute("class")
[code]....
The problem is that (1) this doesnt work at all (2) Is there a way to add the href address and also the outer text?

VS 2008 Listbox Specific SelectedIndex?
Feb 2, 2010I need to make events based on which index is selected in the listbox. I was wondering if there was an inbuilt function of if I need to use If conditions.
vb.net Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
That code will run when the selected index is changed regardless of which index. But I need each index/row to run a different event. I know I can use If conditions to get what I want, but I expect it'd be a lot more efficient with an inbuilt method.

VS 2008 Class And Read A Line From A File And Add It Into A Listbox
Sep 12, 2009I am trying to read a line from a file and add it into a listbox. The SelectedIndexChanged event of the listbox places the selected item (hence, the item I added from the file) into a variable that is declared as a Store (my own personal class.) I can easily add the line from the file into the listbox, but I run into a problem with the SelectedIndexChanged event. When I click on the item in the listbox, I get an error that says "Unable to cast object of type 'System.String' to type 'WindowsApplication1.Store'." (I guess this is because I added an item to the listbox that is from a file.) I tried a variety of methods of casting, but nothing seems to work. What can I do to fix this?

Writing Data From Array In One Class To A Listbox In Another Class
Jul 26, 2011I'm designing a small GUI Windows program that allow staff at a cinema to reserve seats for customers. There will be a total of 60 seats in the cinema. I have two classes in my program:-
1.) MainForm.vb - used for I/O actions and user interaction
2.) SeatManager.vb - used to hold and handle the background methods and functions that make the program work
Here is the code for my MainForm.vb class thusfar:-
Public Class MainForm
Private Const m_totalNumberOfSeats As Integer = 60
Private m_seatManager As SeatManager
[Code]....
Basically, when the program opens, the lstReservations list in the MainForm class will be populated with a total of 60 (m_totalNumberOfSeats) entries to represent 60 seats. Each of these seats will contain the index number from the array m_nameList; this index number (+1) will represent the seat number and then in the lstReservations list, after the seat number, I'd like it to contain the respective entry from the m_nameList array. As all entries will be held in RAM, when the GUI is opened, all m_nameList array entries will be empty. As the user uses the program, they can highlight a row in the lstReservations list and then use the GUI textboxes to enter the customer's name which will then be populated into the respective array entry.
how to, when the GUI opens, ensure that the lstReservations list takes all of the blank entries from the m_nameList array and from there, I can highlight a row to carry out further methods on?

VS 2008 Finding A Specific Row And Specific Columns In Data Base File (Access)?
Jul 24, 2011I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

View 7 RepliesDisplay Data Below Specific XML Tag By Selecting From Listbox?
Oct 15, 2011I just started learning VB.NET about a moth ago (I have been taking classes, so its been about 5 days worth of classes) and I decided to work on this project idea I had. Essentially, it's a database to keep track of anime and manga that I, or whoever else uses it, have watched/read.[code]...
However, now I want to make it so that when one selects a specific title in the list box, it will show the data in the tags below the <series> tag that matches the item selected in a label. One thing I just thought of is than since the list box gets populated in the order that the series are in, it could be easier to go in order from first item equaling the first <series> and so on.

View 2 RepliesUDPClient Class - Tie The Program To A Specific IP On The Local Machine?
Nov 28, 2011Say a machine has two seperate IP's. I am running a little test program that connects to an outside piece of hardware that has it's own IP. I receive data from that hardware. I want the same little program assigned to the two seperate IPs on my local machine to get the same data from the hardware. How can this be done?I am receiving data just fine but I am not seeing how to tie the program to a specific IP on the local machine. As soon as I run another instance of my program, not data is received on the second instance.For example: I have a program running on a machine. I want two instances of that program, each on it's own ip
Instance 1: 192.168.1.240
Instance 2: 192.168.1.241
I want both instances to listen for data coming from 192.168.1.50
This is a generic example of what needs to happen. I need to know how to define the local IP's the UDPClient is running on.
