Allow Only One Instance Of Program To Run (2010 Or .NET Framework 3.5)?

Sep 2, 2010

I'm creating an updater for an IP address, and I need to ensure that only one instance is running on the computer. This is to prevent (or at least make it more difficult for) having multiple tunnels running (it's an updater for an IPv6 tunnel).I've seen various ways of doing it in VB 6.0 and early .NET, but nothing that deals with .NET 3.5 or VIsual Basic 2010.

Change Program To Use An Earlier Version Of Net Framework?

Feb 3, 2010

I wrote a programme and sent it to my client, (it was not a deployment or install file - just the .exe). He responded that it would not run and the PC reported "this program requires Net Framework 2.0". He cannot update the PC in question with Net Framework 2.0. So my question is can i somehow change my program to use an earlier version of Net Framework?

Create A Program With VS2008 While At Same Time It Will Use Microsoft Framework 4.0?

Sep 19, 2011

It might be funny , but I'll ask anyway : is it allowed to create a program with VS2008 while at the same time it will use the Microsoft framework 4.0 ? I am asking because I use VS2008 while at the same time I have the impression that framework 4.0 is "lighter" than 3.5 .

.net - Creating A UDP Packet?

Mar 10, 2009

I'm building a simple udp lan chat application in vb.net and I'm wondering how I should split my packets. Each sent packet should have like an id, a username and ip address from where it's coming and maybe also a command part for like join or leave to update my userlist and a text message. I'd like to know what is the easiest way to put all this in a simple packet then easily split and access different parts from it when it's received. thanks.I'm using UDP since this is only in lan so i'm broadcasting to *.*.*.255

What I want to know is what would be the most easy and powerful way to format my packets so they include a username , an id, a command and a text message, then the user receiving it decrypt it to show only the message written by which user or if it's a command like join or leave to show the appropriate message of joining and add the user to the list for exemple.

Sending TCP Packet?

Mar 11, 2010

first question is: Do you need to port-forward anything in order to receive a response?he sake of all that is good and holy, don't use ACCESS, EXCEL, or a TEXT FILE as a database. If you want your program to use a "local database", without any of the hassle of setting up a MS SQL or MySQL server, just click this link: >>> SQLite <<< Seriously. This is for your own good.

Reading Packet Id From Byte?

Feb 2, 2011

I have a packet that I need to send to a client with an ID of 255. I've had no problems sending packets with IDs of 0, 1, and 2. The ID has to be 255. For some reason, after the translation has happened, both me with my server, and the client, get "63" for any Id greater than 127.

This is the code I am using:

Console.WriteLine(Asc(System.Text.ASCIIEncoding.ASCII.GetString(System.Text.ASCIIEncoding.ASCII.GetBytes(Chr("255")))))

Now, This is an overly complicated version of what the server does. You may consider this a bit unnecessary but the inverse functions performed are for your viewing reasons only.

Where it says "255" is the Packet Id I need sent in the format above. As I said, anything larger than 127 returns "63".

Communications :: Finding Packet Destination?

Jun 16, 2010

I am making a software in VB .NET and I wanted to find out where a packet is directed i.e whats its destination IP .ctually what I am doing is kind of a relay.. means for example - A computer(192.168.1.2) wants to send a data to 192.168.1.10:80 but I make it send the data to my server computer i.e 192.168.1.5 which then sends the data to the destination machine which 192.168.1.10:80 .So basically I want to find out where the packet wants to reach(in this case 92.168.1.10:80) . The structure looks like --Client Computer -> Destination Computer [ In normal case ]But I want to do something like this :- Client Computer -> Server Computer -> Destination computerFor the Server computer to send the data to destination computer I guess I will have to know where the packet wants to reach or something

Read A Packet Of Data Which Has Come In From RS232

Jan 10, 2010

I am trying to read a packet of data which has come in from RS232. I need to be monitoring the port until data comes in to be actioned. I have been doing this fine for some time using the following code:

Dim strline As String = Nothing
Dim comPort As SerialPort
Dim bIsOpen As Boolean = False

[Code]....

The code above works without a problem unles byte 1 or two are greater than 127. Basically, all of the characters that are not converted seem to be 128-255.

I am using VB 2008 express. Clearly I need to read each byte individually and store it as a byte within an array instead of a string but i am not sure how to do this.

how to get around this either through reading bytes properly or through using a different encoding format
