Hello,
I need to detect if is there any audio comming out on the speakers.
I searched all the web and all I couldn't find what I need (or perhaps I didn't know how to look or what to look for  )
Anyway, I need to check if there is any audio playing(media player, web..) anything that comes out from the sound card.
If anyone can help me, it will realy save me.
(I am looking for a solution for 3 days now  )
Thank you in advance,
Anomis

Well, if you can hear anything, there probably is. If you can't, then there probably isn't. Although one can never be sure. You might have a partially eaten banana in your ear, in which case you almost certainly won't be able to hear anything.
On the other hand, if you put a shell suit to your ear, you should at least be able to hear Romford.
Hope this helps.

I believe, although I am not able to access VS at the moment, so cannot be sure, there is a OnMeasureItem event that you can override to return a size that you prefer. If you look it up on MSDN I think there is a pretty good example.

Thank you for your help, Michael Schäuble and Henry Minute
I will test it as fast as i can... 
Edit: I tested it and it didn't work the listview has no om measureitem-Event only the listbox...

Hi!
I'm working on a project that involves translating C++ to VB.NET (me not really being a C++ person) and am really stuck on how to translate the following C++ to VB:
sum ^= (((UInteger)(name[i]))<<(off&0x1F));
Where "sum" in an unsigned integer, name is something that I'm not familiar with, but is declared like this:
char *name
And "off" is also an unsigned integer. Do any C++ people out there have any ideas?
Thanks!

Here's some notes that I hope might help (it's a long time since I did C++ but I think I remember it.)
char *name - declares a pointer to a char, this is a common way to access a string/array of chars. VB.Net equivalent would be a string. So name[i] is the ith char in the string.
(I'm assuming that name is a parameter or that somewhere it has been set to a valid string)
off & 0x1F - is a bitwise and of the variable off and the hex value 0x1F (31 in decimal). Effectively this gives off mod 31 (i.e. remainder after division by 31)
<< - does a left shift by whatever that mod gives. Effectively this multiplies the value in name[i] by 2 to the power of off mod 31.
sum ^= - means that the value in sum is Xor'd with the the result of the modding and shifting.
Now how you translate that into VB is another matter.
One thing to be wary of is that the C++ is probably dealing with 8-bit chars in VB they are probably 16 bit. You need to know where the data that fills the name string is coming from and so how many bits per char.

Hi!
Thanks! I was going wrong with the "off & 0X1F" part, I had them all joined together and it gave me an error. It didn't occur to me to separate them out.
All the other information was very useful too, and has helped me in my project.
Thanks Again!

Just a caveat to riced's excellent answer:
Do make sure off is not 0FF (zero F F) written in lower case.

This has nothing to do with programming, if the error is that you need to configure the permissions on your machine. Nor is it something that you can do in your code, to benefit an end user. I get the impression that you're more than a little lost. How are you sending emails ?

But obviously not serious enough for you to google sidebar visual basic, so just how serious can it be?

I writing a program that is used for data entry for my company. On the main form there is a combo box that is full of different components we may test; things such as doors, window, closets, etc. This is list of components is store in a file in the program's directory and loaded when the program loads and all the different components are put into the combo box. This works fine. Now, when an inspector is in the field they may need to add a component not pre-programmed in. So they can go to another form and add the different components. Once they are finished enter any components they may need to add they click a command button "Done" that then saves the new components to a file:
<pre>
'Check if there are structures in the 'lstStructures' list box
If lstStructures.Items.Count > 0 Then
'Create a new file stream
Dim fs As FileStream = New FileStream(AppPath & "\" & StructureFile, FileMode.Truncate, FileAccess.Write, FileShare.None)
'Create a new stream writer
Dim Writer As StreamWriter = New StreamWriter(fs)
'Loop through each component in the 'ComponentArray' array list
For i As Integer = 0 To ComponentArray.Count - 1
'Save current component in the 'CurrentComponent' structure
CurrentComponent = ComponentArray.Item(i)
'Write the component/member string to the stream writer
'(Structure=Member1,Member2,...,MemberN)
Writer.WriteLine(CurrentComponent.ComponentStructure & "=" & CurrentComponent.ComponentMember)
Next
'Flush the stream writer
Writer.Flush()
'Close the stream writer
Writer.Close()
'Close the file stream
fs.Close()
'Close this form
Me.Hide()
End If
FL_ADDED_NEW_STRUCTURE = True
'Load the structures on the main form
frmMain.ReLoadCustoms()
</pre>
Now the <code>frmMain.ReLoadCustoms</code> should reload the file with the newly added components and add them to the combo box:
<pre>
Public Sub ReLoadCustoms()
Dim fs As FileStream
Dim Reader As StreamReader
Dim div() As String
fs = New FileStream(AppPath & "\" & StructureFile, FileMode.Open, FileAccess.Read, FileShare.None)
'Clear Component Array
ComponentArray.Clear()
'Check if the file is empty
If Not fs.Length = 0 Then
'Create a new stream reader
Reader = New StreamReader(fs)
'Read each line of the file until the end of the file
Do Until Reader.EndOfStream
'Split each line delimited with '='
'(Structure=Member1,Member2,...,MemberN)
div = Reader.ReadLine.Split("=")
CurrentComponent.ComponentStructure = div(0)
CurrentComponent.ComponentMember = div(1)
'Save the component in the 'ComponentArray' array list
ComponentArray.Add(CurrentComponent)
Loop
'Close the stream reader
Reader.Close()
'Close the file stream
fs.Close()
End If
cboStructures.Items.Clear()
For i As Integer = 0 To ComponentArray.Count - 1
CurrentComponent = ComponentArray.Item(i)
cboStructures.Items.Add(CurrentComponent.ComponentStructure)
Next
cboStructures.Items.Add("...Add...")
cboStructures.SelectedIndex = 0
cboMembers.Items.Clear()
CurrentComponent = ComponentArray.Item(0)
div = CurrentComponent.ComponentMember.Split(",")
For i As Integer = 0 To div.GetUpperBound(0)
cboMembers.Items.Add(div(i))
Next
cboMembers.SelectedIndex = 0
cboStructures.Update()
FL_ADDED_NEW_STRUCTURE = False
End Sub
</pre>
The problem is that the new components that were added do not show up in the combo box, but they are written to the file. I have verified this by looking at the component file and because the next time the program loads the new components are present...the problem is that the whole program needs to be reloaded for some reason. Any help would be greatly appreciated as this has been driving me crazy for over a month! Thanks in advanced.
P.S. The <code>ReLoadCustoms</code> sub is on <code>frmMain</code> and the <code>SaveFile</code> sub is on <code>frmStructures</code> and this is running on a PPC.
UPDATE: I have come to realize that for some reason the cboStructures.Items.Clear in the ReLoadCustoms does not actually clear the combo box. Any suggestions?
