I built a power saver program that makes the screen turn black when you're not standing over the keyboard, but it only makes the screen turn black and that probably won't save much (or any) power
View 7 RepliesHow 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?
[Code]...
Public Declare Function PostMessage Lib "user32.dll" _
Alias "PostMessageA" _
(ByVal hwnd As IntPtr, _
[code]....
And here is the actual code to do the task:
PostMessage(Me.Handle, WM_SYSCOMMAND, SC_MONITORPOWER, 2&)
This puts the monitor into standby. Can I please have some help to modify the code to turn the monitor off, and also the code to turn it back on.
I will build a EXE file without form, this EXE file will turn off monitor, then invoke this EXE from command line.The turn off monitor code is below
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As IntPtr, ByVal wMsg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
Private Const WM_SYSCOMMAND As Integer = &H112
[code]....
I want to know what about the MainHandle, because there is no the form in the EXE file (Me.Handles invalid), and only invoke the EXE from command line, in other words, there is no the invoke form (FindWindowA is invalid), how to write the MainHandle?
I found many solutions in C++ however they seems fail to satisfy my requirement. I need code to turn off monitor when i'm away and if i want it to turn on, i must type specified key instead of any key press or mouse movement as usual.

View 1 RepliesI'm looking for a way to get rid of the delay when a user presses a key. The Key_Down event unfortunately is affected by this and I'm making a type of game that needs smooth movement.
My current solution involves a timer and sort of my own makeshift way around it, it's almost perfect but quickly switching left and right keys gets buggy from the key repeat delay.

There both pretty much the same, It almost worked in VB.Net but when declaring "lpvParam As Any", the any part was marked as an unknown variable type. I guess that's something unique to 6.0.
Does anyone know a way to do this in .NET?

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?

Can I monitor the registry for changes similar to how sysinternals process monitor does it in VB? I have checked many different articles and C# samples but not come any closer to getting an answer, I would like to know if there an easier way (a VB sample perhaps)that you folks can share. Ultimately I'd like to be able monitor other things too like file system, processes etc but wonder most about how the registry can be done in VB...Would using system.management be a start? Or WMI? if so is there a nice VB sample..

View 6 RepliesI 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.
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 1 RepliesI 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.
