I want to make a simple program with I can turn on/off litle USB LED.
Nothing special, just one small LED as you learnt in 8th grade.
I think the simpliest way to do this is "powering off" USB port. But how?
I'm using Visual Basic 2008 Express Edition.
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 was wondering if their was a way to for me to turn off events and then turn them back on in my program or just queue them up until i am ready for them to be excuted. Kinda like how a OS turns on and off interupts. Is this one of those general programming no-nos?

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
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.

my query is this: I want all of the characters that are of a membership level in a given area that is of admin or above.
This is what I have so far:
Dim L As List(Of Character) = (From C In MasterCharacterList.Characters.Values _
Where Me.Item(C.CharID).DreamLevel.ContainsValue( _
(From L In _Levels Where L.Value.Admin Or L.Value.BotMaster Select L.Value.MemberLevel).ToList.ForEach) Select C)
Me, in this case, is the members collection.
So far, I can't get the query to turn into a list (hence no .tolist at the end.) I know there's something wrong here, but I'm not sure what.
I would like to turn of this exception in the debug menu but I am not sure how or which one to uncheck or check.."ObjectDisposedException was unhandled"
View 6 RepliesI am making a small guessing game, and I have a numerical number box in the option forms which sets the max number that can be generated. Because of the way I get the variable it wont update that value correctly. To fix this, I have a label which, upon closing the form, is set to the number of the numerical number box, and the max value is gotten from that label. My question is this: How can I convert a string to an integer? I tried one way, but got (i think, i cant remember exactly) a "First class expectation error" and something to do with "vbexpress.dll" (again, not the exact name) This then caused my Laptop to lag up so much that i couldn't do anything, and had to force crash it. So again, my question is this: How can I convert a string to an integer?
View 3 RepliesI have an array of conditions with elements like "thunderstorm", "severe thunderstorm", etc. I want to loop through the elements and, for each element, check a registry key. Then, based on that registry key I want to either check or leave unchecked a checkbox called TornadoCheckBox, SevereThunderstormCheckBox, etc.
Here's what I've got so far:
Dim ConditionsArrayString() As String = {"Tornado", "Thunderstorm", "Severe Thunderstorm", "Hail", "Snow", "Heavy Snow"}
Dim CurrentConditionString As String

I'm creating a program that creates icons starting at images using vb.net in VS 2008.I wish I could rotate an image displayed in a PictureBox horizontally.The intention is to leave as Windows Vista /7 is the view of putting a folder of image files in this folder within a folder.It (the image) is rotated just a bit not totally aware of the front screen.With a program only had managed to do this with Word 2007, using the new "3D Rotation".But I have to do with VB.Net code.I have looked something about using Google, but found nothing useful.

Isn't there any shorter way with bitwise operators?

I get a compiler error, cuz it goes up, instead of negating it.

I'm trying to figure out how the computer will know if the player character has collided with a computer generated character. as the computer generates characters it puts their names in a list box. what i'm not sure how to do is pull the names out of the list box and have the computer check the location property of the picture box with the name that corresponds.

View 1 RepliesI am trying to create a specific aspx page where I display clickable links based on information in a sql database. For example one column could be the anchor tag another column could be the path to the link itself etc. In the past I would pull this information from sql and put it into a non-visible Label (say linkLabel1). Then in the page itself I would insert <%linkLabel1.text%> to insert the link path from the database to the appropriate area.
What I would like to do is set up a way that I could simply enter a new row into a SQL table with link information and a web page automatically displays the new link for me.
I guess I am mostly looking for insight, opinions, or directions of what approach to consider. I can elaborate if I was unclear (wouldn't be awfully surprising if I was not).
