Add Each Href To A ListBox If It Has A Specific Class?
Jun 24, 2010
Ive 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?

I'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?

My XML file looks like this:
<?xml version="1.0" encoding="utf-8" ?>
<Tabel>
<Member>
[Code]....
When more nodes are added, how can I get the value in the <Naam> tags to be added into a listbox?
Note: there isn't a fixed amount of <Member> nodes and they all have to have their <Naam> elements added into the listbox.

I 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.

I 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.

ListBox1.Items.Add("XYZ: " & read_write_str(deviceHandle, xyz, xyz.Length))I get reply from device for i.e. 1234567890, I want this to be in BOLD or if I could add colours to it.

As far as I know, there is no way to grey out/disable specific items in the ListBox control? I want to make a list of surveys that need to be answered, but grey out/disable those that the user has already answered.Or is there some way to do it with ListBox?

In some DLL, I have an interface defined like this (shortened code):
Public Interface wsIInvoice
''' <summary>
''' Perform plugin specific actions for a given memberhip invoice that is processedin an incasso batch, and return success result.
[Code].....
The DLL implementing the interface has a reference to the one defining it. And the defining DLL is imported.
I'm doing exactly the same thing in another DLL, and there VS does not complain.

I have a lot of controls on my asp.net web form that require validation. Rather than list each control in the code behind page that requires validating I would like to add the css class "required" to the necessary controls and then on submit the code behind will validate each control with this class. I'm fairly new to .net so here is some Pseudo code:
Public Sub ValidateAllControls(ByVal a As Object)
For Each c As Control In a.Controls
If c.Controls.Count > 0 And c.Controls.class = "required" Then

I have a function list of 75000 for my project. I want to load each class file dynamically and need to add one line on top of the function and to lines in the ending. Which is the best way to update a specific part of the file. I don't want to make a small mistake here since its my source code and globally using.

Say 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.

Under Visual Basic 2010, I am trying to define a specific instance of a static method that was created as a Java class. I have a vendor supplied dll added in as a reference.[code]...
But, I can't seem to define a specific instance of this method. Using "IntegrationMethod.getIntegrationMode()"always returns a value of zero.
There doesn't appear to be any way to "setIntegrationMode" to a specific value.
The documentatoin for this Class as provided by the vendor are shown below.
When I asked the vendor for assistance, their response was: "
Our javadocs for the IntegrationMethod class show that we provide three predefined instances of the IntegrationMethod class[code]...

I am creating a class that searches a binary file for a specific customer number. I am using a binary search that keeps on slicing the file in half until I find the customer number while is sorted. Once it finds it I am positioning it at the first instance of that Customer number as there can be multiple records with the same Cus Number.
Now here is my question. I now need to loop through this Customers records and do some data base searches. Since I want to make my class as generic as possible what should I pass back to the calling class? An Array with all their records. If I do this I have to loop twice, once in the class and once when it passes the array bac to the original calling class?

in VS 2008, is there a way to design a ContextMenuStrip in a designer without a relation to a specific Form or UserControl class? For example,if you need the same ContextMenuStrip in Form1, Form2 and Form3, in which of them am I to design the ContextMenuStrip? Do I have to add a "pseudo-Form" to the project that contains my shared ContextMenuStrips and create only one instance of that Form, or is there another way? I consider this a programmatic hack, that's why my question is whether the IDE offers something better.

I need to find several hrefs in html like this:
<table>
<tr><td><a href="url1">link1</a></td>
<td><a href="url2"><img src="image.jpg" /></a></td>
</tr>
</table>
Once found I need to add (replace) to each href something like this:
?ID=1
therefore the html should turn out like this:
<table>
<tr><td><a href="url1?ID=1">link1</a></td>
<td><a href="url2?ID=1"><img src="image.jpg" /></a></td>
</tr>
</table>
