You could convert each number to a string using either String.Format or its ToString property, specifying a format that you like. If you do that, you'll have to convert the string back to a number when somebody selects an item; the conversion back to a number may not be exact.
Alternatively may could define a class which holds a number but defines a 'toString' function that formats numbers the way you want (indeed, the numeric format may be defined as a property of the class). Doing this would allow you to easily determine the exact (rather than represented) value of whatever the user clicked on. You could also store any other desired information in your class. If you define iComparable within your class, you could also take advantage of the ListBox's ability to sort its items (which you could not do very well if the ListBox just held strings.
Public Class numThing
Implements IComparable(Of numThing)
Public myVal As Double
Public Overloads Function toString() As String
Return myVal.ToString("0.0000")
End Function
Public Function CompareTo(ByVal other As numThing) As Integer Implements System.IComparable(Of numThing).CompareTo
Return myVal.CompareTo(other.myVal)
End Function
End Class

That will only work in VB.NET. Besides, there's a better format string which adds commas (or substitutes) - "N5"

Parlez Anglais, svp. It's considered rude to post in French, and it will limit the amount of answers you'll get - since not everybody is able to read French.

And your thread title is dumb which matches the message content well.
Any suggestions, ideas, or 'constructive criticism' are always welcome.

My French is really bad, but to save some time for those who feel like ending the day with a little gentle mockery with Google Translate, the question is along the lines of "What is the process for installing a program to capture a picture from the webcam using Visual Studio 2008 and Windows Vista?" The answer of course, is to download the program from the Internet, then double-click on the installation program

First, this is an Enlgish speaking board.
Second, noone cares about you email address. You won't get any replies sent to it.

Maybe some spam for those dumb enough to post it here.

Whether you run/compile your application? If Yes, then Navigate the Debug/Release folder of your project directory which contain EXE
|
|
|

Find an assembler or a compiler, some good books and an empty room

Convert the source to a hexadecimal representation of assembly code, then save it as an EXE file. Alternatively, you could just press F5 to debug the program, and F6 to build it. The finished program (and perhaps some none-standard references) will be in your project file, in the Release folder. Double click it to run it like any other program

Yes, but I just wanted to see if he would follow instructions when he was given them. It was either hand-coding the executable file or using a magnetised needle with a very steady hand

Buy a book and read it. Try learning some basics and showing some initiative before posting here expecting people to answer the most basic of questions.

Hello,
I am trying to write a program for my Pocket PC 2003 edition, which can receive and / or transmit IR data.
I know that depending on the device, I will need to know some very specific information to properly send the data that I will want to send. However, for the time being, I would be happy just knowing how to send any old bytes of data that I choose.
The problem mainly lies in the fact that I don't know Socket programming, I guess. So far all I have is:
Dim IR As Socket = New Socket(AddressFamily.Irda, SocketType.Stream, ProtocolType.Unspecified)
Where do I go from here, if I wanted to use the Socket I declared (IR) to send or receive data through my Pocket PC's IR port?
As I sit here, I contemplate the last words of Socrates: "I drank what?".

Mind you, I have no IR or mobile development experience...
How you do this depends on how the IR device is exposed to you. You'll either be using Sockets or you might have to switch to using serial communications (COM1, COM2, ...) to talk to the other machine.
You might gleen some information on how to do this from this article[^].

I have been trying to use socket communications so far, but whether I use that or serial communications, I'm having trouble just setting the connection up in the first place. I've actually been trying to understand how to use either in a desktop setting as well, to no avail.
For the socket communication option, I am having problems defining the EndPoint for the Socket.Connect method. This is what I have so far:
Dim IR As Socket = New Socket(AddressFamily.Irda, SocketType.Stream, ProtocolType.Unspecified)
Dim EP As System.Net.EndPoint
Dim SA As System.Net.SocketAddress
SA = New System.Net.SocketAddress(AddressFamily.Irda, 1)
EP.Create(SA)
IR.Connect(EP)
IR.Send(New Byte() {1})
IR.Close()
This doesn't work because the EndPoint (EP) has not been assigned a value. EndPoint also does not use a New constructor, so I guess I'm just not sure how to declare it.
I would just use the IRDA namespace, but my project is (like so many others') meant to communicate with remote controls and other "dumb" IR devices, rather than communicating with another Pocket PC or Windows based device.
I realize the complications involved in communicating with such a device, but right now my main concern is even being able to send or receive any data at all. I figure I'll sort out the data format after that.
Anyway, I don't know C++, but I will check out that link and see if I understand it.
