I want to send data of bytes from .net server to flash client. i have created a simple .net tcp server but what code would i need to create the flash tcp client in order to receive bytes NOT string or xml, just bytes?
View 1 RepliesI'm trying to send a 28 character string to a remote ip address and port. I've done this successfully in vb.net using the following code snippets:
Dim swon As String = "A55A6B0550000000FFFBDE0030C8"
Dim sendBytes As [Byte]()
sendBytes = Encoding.ASCII.GetBytes(swon)
netStream.Write(sendBytes, 0, sendBytes.Length)
I now have to convert this across to c++ and have the following so far:
char *swon = "A55A6B0550000000FFFBDE0030C8";
array<Byte>^ sendBuffer = gcnew array<Byte>(bufferSize);
sendBuffer = BitConverter::GetBytes( swon );
tcpStream->Write(sendBuffer, 0, sendBuffer->Length);
but am getting stuck at this point. I'm sure I'm missing a simple syntax error but I can't figure it out!To clarify, I'm not getting an error, but I don't think the string is being converted to bytes correctly as when I convert back, I just get a '01'
first asking an question and then introducing but i kinda need some help in here.First of all im not new to VB, But i am to VB.NET and espessially socket programming.Now i need an way to send the lenght of the string being send in bytes before the string itself so <lenghtinbytes><string>.
ive tried so many things, and its possible because the client itself does it too...but just cant find an way.

I would like to use the USB port power as source and use the an amplifier on D+/D- Twisted Pair signal wires as my command line. I saw a thread suggesting to use the output as PWM. How can I send a single byte or stream of bytes to the port. Is it possible to read status of the D+/D- if they are shorted together?
View 7 RepliesI didn't found any performance counter that would monitor an process's/thread's network bandwidth and not just that of an ethernet card.
So I could see how much bytes did an application receive and send.
Did I miss something or is there another way?
I am using sockets and such for a while now, and want to go an step further in this. Now for example lets say an client would send [lenghtofstringinbytes]string[somethingelseinbytes]another thing.
How can I send/read/parse it?
Now I am doing this:
Private Sub onDataArrival(ByVal ar As IAsyncResult)
Try
Dim obj_SocketState As StateObject = CType(ar.AsyncState, StateObject)
Dim obj_Socket As Socket = obj_SocketState.WorkSocket
Dim sck_Data As String
[Code] .....
So using Getstring for it, but thats not the way for this as you get nothing else but an empty string back. So I have to parse it without converting it to an string.
vb.net send a bunch of data to flash. i.e i want all data in a listview will be send in list view of flash and vice versa all items in flash will be send in listview of vb.net ?
View 1 RepliesI want to send data from vb.net to the flash.(ex. i have variable x in .net which has a value of 5, now every time i load the flash in vb.net the value of x will reflect in the text i put in the flash.). I was able to made this but through loadVariables() in the flash but I should save the data in txt files so that the flash will load it.., I want to make it simply because I need to fetch data from the database and then i need to save it to txt file in order to load the data.

i'm tying to send email in my application directly by the smtp server but the server doesn't allow me to do that.The application its used by everyone in the company, so i set the smtp client UseDefaultCredentials to True, but the server replies with this when i try to send an email:[code].....If i set the credentials by hand, the server sends the email. So my problem is how to make this work to everyone? I don't want to have one public/friend var all time in the application with the credentials of the current user?

View 2 RepliesI want it to do is that you input a string, then you select an algorithm (Theres only going to be one RijnDael) then you input a key, then the Initialization Vector comes from "txtIV.text" then you select the key bytes and the block bytes from the numeric up/down, then you either encrypt or decrypt.
View 1 RepliesOk i am having some issues designing a base-class to handle generics.Caveat is i need to restrict the type put in as a Numeric type, specifically Int16, Int32, or Int64 (Short or Long).I know you can do Of T as {Structure} but i dont want to select the key bytes and the block bytes from the numeric up/down.
View 2 RepliesI keep getting a ProtocolViolationException "Bytes to be written to the stream exceed the Content-Length bytes size specified." on the following code.I've tried setting Content-Length numerous ways with no success.
Dim url = "https://domain.com"
Dim req As WebRequest = WebRequest.Create(url)
req.Method = "POST"
req.ContentType = "application/xml"

What exactly does this line do?
i = stream.Read(bytes, 0, bytes.Length)
Does it read the entire message string sent by the client? I have a line to write to the stream later in the code and that does not seem to be sending anything back to the client, although the code around is excuting.
i = stream.Read(bytes, 0, bytes.Length)
While (i <> 0)
Try
' Translate data bytes to a ASCII string.

View 7 RepliesHi, I'm just beginning to teach myself how to do OOP in VB 2008 Express. I have a quick question after seeing a video online.Is a VB variable the equivalent of an 'instance' in Flash and a VB object like a 'symbol' in Flash? Is this what it means by a variable being a reference or pointer to an object and not the object itself?

how to create a client/server... But I couldn't... I don't want anything fancy. Just want the client to send the server 4 numbers, depending on the user's choice; after that, the server would turn off the pc, restart it, etc. It all depends on the number received. Is there a rather "simple" way to do it? If it's not to much trouble you could use Atheist's example. (Btw I don't understand the code and, yes, I've checked on [URL])
