Communicate Using LAN / NIC Port?
Mar 4, 2009I am trying to send and receive packets over the LAN (i.e. NIC port) using VB.NET. I found some code that uses Socket wrench, but problem with such solutions is that users will need to install extra drivers and all which I do not want. I am looking to use drivers native to the .NET environment to send and receive packets through the LAN port. My windows forms application is in VB.NETneil

.Net To Communicate With A Small Unit That Outputs Data Via A Serial Port
Oct 15, 2010I will be using .Net to communicate with a small unit that outputs data via a serial port. I have used an application that monitors the data between an application and this little box. What I see is functions such as IRP_MJ_CREATE, IRP_MJ_READ, etc. At first I thought I needed to build functions and I would send these via the serial port (a novice thought) now I see that the above functions are part of the Windows Driver Kit. So is it true that I call these functions in my code and then the underlying drivers communicate to the serial port and the approppriate data is seen at the serial port. So for .Net (VB) I need to find and use the appropriate functions and communicate to the serial port.

VS 2005 Accessing A USB COM Port?
Nov 17, 2011I have am using an XBee ZigBee wireless module to communicate with a project of mine. I currently have it set up to the point where I can open a hyperterminal session to COM 4 (which is the usb com port), and recieve the data that is being sent via the microcontroller on the other side of the wireless link.
I would like to make an app that takes the data and puts it in to a more user-readable format. (Via VB 2005) So far all I have come up with is some problems. It doesn't seem like I can use the built in serial port tool to access a "virtual" com port. From the following link:Quote:
Note You cannot use the Microsoft .NET Framework classes to directly access other types of ports, such as parallel ports or USB ports.[URL]..Do I have to use a "COM port redirector" to make it seem like a real COM port? Or is there some easy way that I am not thinking of?

[2005] Accessing Device On USB Port?
Nov 10, 2008I have been doing some research into accessing devices on a USB port and it's kind of helped, but not really. From what I understand, I can use the IO.Port namespace to access a device on a USB port (usually). Let me know if this is incorrect.
First, I made a simple program that looped through the ports available. I get COM1 and COM3, but I have 4 USB ports. Where are the others?

.NET 2005, Serial Port, Dispose Windows CE?
Apr 12, 2011I write program for Windows CE that should work with Serial ports. I use object System.IO.Ports.SerialPort. Everything works well but when I close program and open it again, I receive error: Port is in use! At the end I write:
port.close()
port.dispose()
And If I add this:System.GC.collect() than everything begins to work But problem is that computer gets stuck when garbage collector is called for each port. If I tried to use collector somewhere else, it doesnt "collect" ports and they look like used if program starts again.

[2005] Serial Port Genius Wanted?
Jan 13, 2009My app runs perfectly with debug but I'm having a couple of little problems with the actual build on another machine.'m getting a "safe handle has been closed" (most of the time, but not all the time) when I button click out of a certain area.The problem, no doubt, is related to the serial port and I think I can solve it but I do want to ask something very basic....I have several points in the code where I'm doing a serialport.open and serialport.close....and clearing some registers etc.....like I say, in debug all is well.
View 4 Replies[2005] UnauthorizedAccessException Accessing Comm Port
May 3, 2006I'm debugging a VB app where I'm using a comm port attached to a bluetooth radio paired to another bluetooth radio in order to communicate with a remote barcode scanner. The pair of bluetoooth devices basically work as a serial cable replacement. Sometimes it works fine, but after a while I get an UnauthorizedAccessException message which breaks the program (see attached jpeg).
I only get this when I use the radios and not when I use a direct cable. I wonder if it has something to do with other bluetooth devices nearby trying to communicate with mine. I've used the .NET Framework 2.0 Confuration tool to adjust the zone security to give full trust to MyComputer, so I don't think it has to do with security, but I'm really going beyond my area of expertise here. I don't know what's going on.
