my goal is to control the incoming and outgoing packets to a game server, to alert when a game round finishes the main code is this:
Private Buffer(65535) As Byte
Private RawSocket As Socket
Public Event PacketReceived(ByVal PacketBuffer() As Byte)
[code]....
this code works perfectly with XP (you can read both incoming and outgoing packets to the game server)... with Vista the same code displays ONLY the incoming packets....
my code doesn't seem to work on windows XP but does work on Windows Vista and 7.
Code
Imports Microsoft.Win32
Public Class Form1
Dim rValue, rsvalue As Int32
Dim Regkey, RegKey2 As RegistryKey
[code]....
Using the Socket raw, with XP I can read without problems both the incoming packets and the outgoing packets. With Vista (I have tried also others Sniffers) is impossible to see the outgoing packets...WHY? what I have to do to see alse the outgoing packets? In reality I have not to read packet data or packet lenght... I need only to count the number of incoming packets and outgoing packets... but with Vista this job seems impossible... or not?

Once we moved the compiled version over to Vista Home and Ulitmate the emoticons would not show, we have looked and looked all over google and have not come to a conclusion, today we even moved the whole Project folder over to Vista, ran it in debug mode, and the images still wouldn't show in the RTB.

View 1 RepliesI have written a console app in <acronym title="Visual Basic">vb</acronym> .net 2003 to capture audio data (albeit not for an audio application) using the WinMM API. This works well in XP and also on my own Vista PC. However when others try to use in on Vista or Win7 it stops working after about 10 - 30 seconds (so it manages to initiate recording from the default input device but eventually stops). The only error given is "Program has stopped working". I am wondering if this is related to the way I recycle the input buffers?

I wrote a Socket Client which will send the Socket Server some data and get some response from Server. This process will be running once in every 2 seconds.
Now what I need to know is How we can identify the connection lost between Server and Client?
I need this to be implemented in the Client side. If there is no connection then Client should automatically close the connection. Once the connection with the server is available in the next attempt it should connect automatically.
Below is my code, but when i send the message thru client socket i receive Specified argument was out of the range of valid values. Parameter name: size
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim serverStream As NetworkStream = clientSocket.GetStream()
Dim outStream As Byte() = _
System.Text.Encoding.ASCII.GetBytes("0800822000000000000004000000000000000920092126012345001")

I am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.
how to do socket programming in VB. I'm using VB.NET 2008 and i'm a novice but with a reasonable understanding of programming so I want to learn by examples and understanding it in a novice/intermediate point of view. Essentially, I want to create a simple TCP or UDP client that can connect to an IP and port and retrieve the stream for parsing of content.
View 5 Repliesbefore you say something like "just search the forum for socket programing examples" I did and came up with things that were to complicated for me e.g multi threaded etc even a chat server that holds users names in a hash table i couldnt quite grasp so im asking if anyone can give me a few pointers maybe link me to a website that i havnt stumbled apon in my google seaches that contain infomation just about basic tcp server that recieves text strings no fancy users or anything like that.

View 1 RepliesI am using Async socket class to handle HTTP data. The OnRecieve event handler looks like this:
Private Sub sck_onDataArrival(ByVal sData() As Byte, ByVal BytesTotal As Integer) Handles sck.onDataArrival
Try
Dim ms As New IO.MemoryStream(sData)
Dim returnImage As Image = Image.FromStream(ms)
Picturebox1.Image = returnImage
Catch ex As Exception
Debug.Print(ex.ToString)
End Try
End Sub
I realize this will not work because the byte array still contains the header information from the response from the server. How to strip this data without converting the byte array to a string. I need to strip the header response information and just be left with the image data and from there convert that data into a stream so the stream can be loaded into an image and displayed in my picturebox.
i need a little advice/help here. There is a particular scenario that is coming up and I am clueless as to how to go about it."I will soon have a lease line through which I will get realtime stock market data. This data will be available every second and it will contain prices of stocks. Now assume I am able to get that data on my local computer. How can I transmit data so that users can get that data through my software.
For e.g. assume it's 11 AM. Now if you select a stock e.g. Google, then my program should fetch data for google till 11 AM and also show new data every second or so with minimum lag. Something like a terminal where you see stock prices getting updates every second. In my case I need to get past data and show current data which get updated at short intervals."
Now I have a linux vps webserver which hosts my site. (I get one or two static ip free) What to do so that data goes from my local computer to my server and then my program (developed in vb.net) is able to get it and show it to end user. This whole system should such that its fast (real-time) and delay is minimum.
im trying to detect if the connection is still active upon trying to send or receive anything. Now I have checks in place if it's connected then it will send or receive however... it's saying it's connected when it is not connected... and therefore my program tries to send and receive and errors.
I am determining if it is ok to send and receive by using the Socket.Poll(-1, SelectMode.SelectWrite)
if it's true then im connected and data can be passed..This seems to always be true until I send something and it fails..How can I catch the socket not being connected before it fails upon sending or receiving?
I realize this is a broad question, but how do I recieve / send packets. I know what packets I need to send and what Im going to recieve, but I dont know how to send / recieve them.

I have been working on recoding a VB6 client/server application of mine and have run into a bit of an issue with storing the players location on the tile map which means I will need to rework the way I am storing the user connections. In my VB6 application I would store the user's numeric index/socket number/whatever you'd like to call it as the Key, however, in VB 2008 I can't seem to find where, or if, the numeric index is stored. If this isn't possible then does anyone have an example of how they store user connections using some numeric index as the key of a hashtable?

View 3 Replieswindows service app I am developing to audit events in the Windows Security Event Log. I am using the EventLog class to read entries from the "Security" event log. I have set the log to raise events when an entry is written so I can parse the data. Here is where my problem comes in. If I run the service on Windows 2003 I can get all the data I need from each entry, but when installed on Server 2008 the EventLogEntry ".message" property comes back with useless data like this, "The description for Event ID '4738' in Source 'Microsoft-Windows-Security-Auditing' cannot be found." Under Server 2003 the message property has good data. Using the Event Log Viewer in Server 2008 I can see that it is rendering the correct data, but I am having a heak of a time doing the same. The "replacementStrings" property has the corresponding data that I need, but it appears to involve some other steps to get the data localized to the event provider, but I do not know how to do that.
I also checked the registry HKLMSystemCurrentControlSetServicesEventlogSecuritySecurity on both the 2003 servers and 2008 servers. They are identical execpt the 2003 has an entry the 2008 server does not:
String Type: GuidMessageFile
Value: %systemroot%system32NtMarta.dll
Im on Chaper 10 of Microsoft Visual Basic 2008 Step By Step, and I just dont understand how a module works. Ive the chaper over and over and i still don't get it.
