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 have code bellow. Why it doesn't work?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
SendKeys.Send("{NUMLOCK}")
End Sub
Is any way to cancel this key. I need him to be on all the time without the possibilty to turn him off manually.

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?

View 2 RepliesI have a search page with a couple of pulldowns. Dependig on the values of them I show a grid matching the searched criteria, basically a table with links the user can navigate to. My problem comes when the user wants to navigate back. At the moment I have a "Back" button which simply redirects the user to the initial search page. I think it would be a good improvement to have the values of the pulldowns filled in with the values the user selected, this way when he presses the "Back" button he would not have to restart the whole search process again.

View 3 RepliesWe have a server application and a client application that communicates with each other using socket.
When the server application sends 2 messages about 16-31 ms apart, the 1st message is received by the client application with little delay (like 16-32 ms after it was sent). But the 2nd message is received by the client application a lot later (like 200 ms later) than when it was sent.
We already disabled Nagle algorithm (set NoDelay = True) in the socket in both the server and client application.
We are having problems with sending back to back emails on one of our web sites. The site is built with .net framework 2.0.We can send the first email without any problems on every try. But to send a second email you need to wait about 20-30 minutes.the problem.One thing we tried was changing the smtp email server. We tried a third party smtp server but the same problem persisted. So I think the problem is not with the smtp server but with our .net code.

I am creating an application that will be faced with multiple decisions to make and I want to know if it is possible to create around 20 if statements to excute or decide between before excuting?
The application will encounter multiple websites but each website will have the same elements but not neccessary in the same order so I was going to tell the app to loop through the IF statement and if the condition is met to run that sub routine where it starts over and loops through the IF statements until next condition is met.
Is this possible in VB.NET or is 20 or so IF statements to many to use at once?[code]...

How do I turn off a monitor using VB.NET code? OK, actually I found the C# solution. But I need the VB.NET solution. I have tried an online C# to VB.NET converter, but the converter is complaining that there are errors in it.How can the following C# code be translated to VB.NET?

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?

Isn't there any shorter way with bitwise operators?

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