I have a desktop computer with a cable connection on the back that allows me to watch TV on the computer using Windows Media Center. I had the idea of writing a program that would access this feed and send it to another computer (laptop) via my network. That way I would be able to watch TV from anywhere that my network spans. I have no idea if this is possible or how I would even do it,
So I have three questions.
1: Is it possible?
2: How would I go about access the feed?
3: How would I send it over the network?
My original thought was doing it in Flash, but I'm not very good at Flash so I wanted to do it in VB.Net.

What is a method to detect if NumLock is OFF and how to turn it always back ON automatically when my VB APP is running ?
EDIT: My app is dedicated app, running on dedicated computer with external numpad device.
another option would be to ACCEPT NUMPAD ARROW KEYS (etc) and convert these to NUMBERS on fly, is it possible?? (e.g. ignore the numlock off situation and behave as numlock is on)

I was wondering if I could regulate/change CPU fan speed or just turn it off with VB? And also, I thought if windows can change hard drive speed during worktime, can I also make an application with VB to change hard drive speed? RAM speed? Processor speed? Video card speed? Wanna do a kind of custom overcklocking tool.

On programming assignment without having any real experience in vb. I guess I don't understand subroutines that well. When the program runs it never goes to the computer's turn and does not update the users score either. This assignment is already in but would like to know what is going wrong. Using VB 2010, and this is windows application.
Code:
Public Class Form1
Dim Myturn As Integer
Dim Computerturn As Integer

What I am trying to do basically is open an access query in a datagrid view and then be able to make changes to the datagrid and then save it back to the database.When I try to save:
Me.BindingSource.EndEdit()
Me.TableAdapter.Update(DataSet)
It says that update is not a member of the tableadapter... Why is that?

building a program at the moment that changes registry entries to turn on and change, and off proxy settings. This small program is going to be dropped on each persons desktop so they can easily turn on the proxy in work, and turn it off when they take their laptop home.
However, the proxy address changes depending on which company I am at. I would like to be able to make a single program, but have a "hidden" setting to change the proxy and store it in the program, and push a copy of the file out across the network to each machine. I tried to make it so the proxy address can be saved as a string in My.Settings, but it would have to be made as a User setting rather than an application setting to give it read-write access.The only other option I can think of is to hard-code the proxy address into the program, which really isn't ideal

Right now I can add background music in my program by using this code
My.Computer.Audio.Play(My.Resources.Music_3, AudioPlayMode.Background)
I can also turn it off and change the music by using this code
My.Computer.Audio.Stop()
My.Computer.Audio.Play(My.Resources.Another_Music, AudioPlayMode.BackgroundLoop)
Is it possible to pause the music then if I resume the music it will just continue the flow? I mean if I pause the background music in 33 seconds and the music has 50 seconds and I resume it will just continue playing in 33,34,35 etc.. seconds?

I have a situation where my program saves a file on a regular basis under certain circumstances. Every once in a while, power will fail and the file being written will be gone, I assume because it was in the process of being written when the power failed.So I need a solution that will prevent that situation while still using just one primary file to save the data.
My proposed solution is to write the file to a temporary file, and then copy the temp to the original and then delete the temp. Therefore in the event of a power outage, either the the original or the temp file will always be there. Are there any obvious problems with that method?

We all know what a Static variable means! Recently I came across a problem that I have no idea about! I even don't know whether I'm wrong somewhere or that is a VS fault. Whatever it is, I can't figure out the cause. Anyway, I simply opened a VB 2008 project and added 2 Windows forms to it: Form1 and Form2. Then I set Form1 as a MdiContainer by setting its IsMdiContainer property to True. Then I added a CommandButton to Form1 and put this following code into that:

I'm currently working on a VB. Net web service calling another web service running in the mainframe. I was provided with the WSDL file and I generated a proxy class using wsdl.exe. Upon attempting to invoke the method of the mainframe web service using the proxy class, I encountered an exception saying "Conversion from SOAP failed" coming from a line of code in the generated proxy class.
