Communicate Using LAN / NIC Port?

Mar 4, 2009

I 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, 2010

I 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.

Communications :: .net MSComm Port USB 4 Port Relay?

Oct 20, 2011

I am trying to get my 4 port USB relay board to work in VB.net using the COM PORT. I found some code from a poster who has the 16 port USB relay version. When trying his code i can only get it to turn on relays 1-3 all at the same time. The product can be found here: USB 4 port relay

"01+//" - Relay 1 is switched ON
"01-//" - Relay 1 is switched OFF
"02+//" - Relay 2 is switched ON
"02-//" - Relay 2 is switched OFF

[code].....

So i am confused as to how to separate each relay out with that code above and just be able to turn on any number 1-4 relay on or off independently from each other!

PHP Communicate With .net App?

Mar 15, 2010

I'm working on a little app which needs to recieve information from a script on a web server. I tried to have the vb.net app pole a php web page for a command every half of a second. This worked but, the app is streaming video and every time the app needs to pole the webpage the video stutter stops. I tried setting the pole timer to 5 seconds and still every 5 seconds the video stutters. I thought that maybe sockets would be the answer, so I looked for examples of vb.net socket servers and php socket clients. I tried implementing a solution but the php cannot seem to connect to the vb.net server. I googled around and saw that maybe php cannot communicate with a vb.net application.

Communicate With Another .Net Process?

May 8, 2009

I have a library that interacts with our phone system, ie, Hey phone, call this number for me. This library is used in one of our in house products. I would like to put this instead in a service, so that any of our in house products can send the service a message to place a phone call. So basically I want to communicate from a program built in .Net 3.5 with a service running on the same machine also built in the 3.5 framework. I have done some work with WCF and was considering using this but thought I would ask what others have done or would do.

.net - Communicate/Send Image To App?

Aug 12, 2010

I am writing a VB.Net application wherein I would like to be able to communicate with it from a remote computer. Specifically, I would like to be able to send (from a remote computer) both text data and also images (jpg, png, etc.) and then have the application use the sent information by displaying it to the user. How would I code the VB.Net app to be able to handle incoming data like this?

If possible I'd like to not be dependent on .Net technology on the "sending" side so I'm not sure if I would just use sockets or a web service or what.
