Detect If NumLock Is OFF And Turn It Always Back ON?

Jun 2, 2009

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)

Turn Off And Turn On Background Music In Program

Feb 17, 2012

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?

Can't Get The Query To Turn Into A List

May 12, 2009

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.

How To Turn A String Into An Interger

May 11, 2011

I 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?

Turn On Leftmost Bit Of A Short?

Jul 8, 2010

I want to bitwise turn off the left most bit of a Short value (&H8000) and leave the other bits as they are.

Dim x = BitConverter.GetBytes(Short.MaxValue Or &H8000)
Dim z = BitConverter.ToInt16(x, 0)

Isn't there any shorter way with bitwise operators?

When I do

Dim a = Short.MaxValue Or &H8000

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

Asp.net - Turn Sql Rows Into Links On A Page?

Apr 4, 2012

I 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).
