Block Connection To An IP Address (Incomming And Outgoing)?
Oct 25, 2009
Is there a way I could block connections to an IP address (Incomming and Outgoing) in visual basic 2008? I have a different method, using the windows hosts file. I could make it redirect, but on the host file, could I make it launch a certain application when it blocks an IP. Like, launch a file called blocked.html that says "Webpage blocked" on it? and if u get this far, how can I see when an app attempts to connect to the internet. Like on bit defender firewall, say aim6.exe trys to connect to a server, how could i warn the user of this???? (Maybe using winsock)

I'm having a problem with some users, my vb tools always check at the splash screen a response from a server with a simple:
Dim MyResult as string = oWebclient.DownloadString("www.mydomain.com/page.php")
This actually works for most users but in some clients the firewalls I think they block this call or bypass or something like that, I found that after telling the user to turn off the firewall everything works ok, now I have some users that according to them they don't have a firewall or they already disable and still they have the problem.
You can see from the image the error message they receive, so my question is do you know any kind of free tool that I can send to the user to maybe log what program or whatever is blocking the program to connect?

I want to start a new project on PC and Mobile Phone. But i'm still have so many question about the communication between PC and Mobile.
My project List:
1) My idea is establish a connection between PC and Mobile through IP address in first, but my question is 'How to do it' ? izit same like PC to PC by using Winsock open a port to access? i'm using VB.Net 2005 for PC and Net60 for mobile.
2)My mobile phone Nokia 6220 Symbian OS is support GPRS/3G. Since the GPRS/3G can connect to the internet, izit means mobile itself have a IP address and service provider in order to surf the web? So, can i connect my mobile phone to PC through this gateway?

m new in Visual Basic programming, recently I have developed an application to send and receive UDP packets using the Socket Class. Everything is working ok, but there is one more thing I have to acomplish, which is specify the outgoing UDP port for outgoing packets (SendTo method), I need to do that because the application in the other side just process packets from an specific UDP port at the origin

It doesn't look like much is out there after searching but I was wondering if anyone has seen any vb.net projects to create a simple outgoing telephone dialer? Maybe something that can talk to a PC modem?
I'm not sure but was even wondering if this is something that can be done in a procedure? Doesn't look like there are any features that lend itself to it.
I thought also, I may do something with an RS232 stream and then use an external hardware dialer.....if I did that, I'm sure I could do the code in a Sub.

Recently I've been into PBX call accounting programming on VB.Net 2010. My results are way too successful including friendly user-interface and connection datareceiving coding. Except for one. That is the call duration of calls, incoming and especially those outgoing. In my project I didn't use any API (like TAPI for PBXs) thus is there any option how to detect the state of the outgoing call, whether is still ringing, ended without answer or answer at some point of time...because in my project nevertheless what call state is being processed, I'm getting the total call duration from the moment that call was initiated to the moment is being finished or not-answered.
Here is a sample of my project where the DataReceived event is fired whenever there's something to parse from PBX to the PC.
Programming language : Visual Studio 2010 Ultimate - Visual Basic .Net
Database : Microsoft SQL Database
PBX Machine : Panasonic KX-TEM824
P.s. If you need to provide some code I'll post a sample of my project where the DataReceived Event is being handled.

I'm trying to use the DHCP API (using the references on pinvoke.net) to retrieve a computer's MAC address when given the IP address but I can't get the code to work. I've run all the C# code on pinvoke.net through the C#-to-VB converter but I'm stuck now.
Here's what I have so far. The value of res is always 5 (should be 0). Thing is, I can't find any documentation on what the return codes mean
vb
Private Sub GetMACDim client As String = "1.1.1.1" Dim server As String = "0.0.0.0" Dim si As New NativeMethods.DHCP_SEARCH_INFO si.SearchType = NativeMethods.DHCP_SEARCH_INFO_TYPE.DhcpClientIpAddress si.ClientIpAddress = Convert.ToUInt32(StringIPAddressToUint32(client)) Dim res As UInteger Dim oInfo As IntPtr

I have a server which has around 300+ users on it. Though the problem is that its coded in VB6, and if somebody has a bad ping, everybody has a bad ping. I need a tunneling server which will tunnel the incoming and outgoing connections and make there ping appear to be 0 in the server. Client to Server, Server to Client.
