Sep 30, 2009How can I set a host IP address and port.. and then detect if the port is open (accepting connections)or closed (denying connections)I came across this while searching, but it doesn't seem to function all that well..Using the port 80 and the host [URL] The result it gave me was closed... which is obviously wrong.So what can I do?Code: ( I have also imported "System.Net" and "System.Net.Sockets" )

Get Ip Address And Port Number Assigned By .net?
May 30, 2011I have 2 winforms, one acts as server (ie Winform:Server role) and another one as client (ie Winform: Client role). In my LAN setup, there are 6 PCs and these PCs connected to each other via a 8-port switch and each PC has more than 1 LAN card.
There is one PC running [Winform: Server role] and 5 others running the [Winform: client role]. In [Winform: Server role], I'm using following code to obtain local ip address and port number and the [Winform: Server role] will listen to all incoming TCP requests according to these auto assigned ip address and port number.
Dim Listener As System.Net.Sockets.TcpListener
Dim Client As New System.Net.Sockets.TcpClient
Dim Message As String = ""
[Code]....
I need to clarify my intention. My current approach to my intention maybe incorrect. I attempt to create a 'zero configuration client-server networking' and that is plug & play. The server will know where the client and vise versa. I know there is a program (i.e. MaxiVista) has done that exactly.
MaxiVista has 2 applications, i.e. server and client. Users only need to execute the server application in PC designated as server role and execute the client application in another PC designated as client role. Then the server will be able to find all executing clients in the same LAN.
My intention is just that. Plug and play 'zero configuration client-server networking' within the same LAN.

View 1 RepliesPrint To Label Printer Via IP Address?
May 26, 2009I did search the forums pretty well, but did not find a clear cut answer or direction. My question is I am currently building a windows form application with VB.NET and I need to print a label to a Zebra label printer which is on the same network. The printer it self has a print server on it so it does have an IP address, but I do not believe it has a name so I would be printing to the IP address. I have seen several people use both PrintDocument and TCP route, but I am not sure what would be the best way. What would you say the best way to do this is?

Program A USB Port?
Jun 5, 2012I'm confused , in the old days if I wanted to access a parallel or serial port I would simply set up the appropriate registers and read/write to I/O Registers. but USB is a whole different animal. Lets assume I plug device X into a usb port How do I find where the pc, or manufacturer has placed it? If it's a ddl then what is my fetch? if it's a virtual port where do I find the virtual irq and read/write port? What if it's a dongle, where do I find it's read registers? what if it's an external piano, where do I find it's sound out read regs etc.

1. It only gets the first 4 bytes(is it?) of the memory address. I want it to get all of them.
2. I haven't discovered how to convert each byte(?) into a character. Is there a function for this?
3. When the program runs, after clicking ok on the MsgBox, it highlights the Next and debuggs:

View 3 RepliesPort Forwarding With Program?
Apr 6, 2010I am looking to write a VB.NET windows app or service to do simple HTTP port forwarding. This is normally done within my router, but I have more forwards to do than the router can support (10) so I would like to do it programatically.
Quite simply, an HTTP request would come in on a port where the application/service is running, and it would automatically forward the conversation to another IP address and port. That way, my router could forward a range of ports to one machine (where the application/service would be running) and the application/service would dole the requests out to the various IP/Port combinations it was listening for.
