Create Sockets And Communicate Over Them?
Mar 4, 2009
I am actually new to VB.net...i have managed to create Sockets and communicate over them..but i dont know how fire sql queries through sockets as they take in Byte data as a input...i want to actually pass queries through sockets and retrive those results...i am using mysql database....i have actually tried changing the connection string (the ip address) for a static network but i think sockets are better for dynamic ip networks.

I have a VB application where winsock is used. I want to convert it to VB.Net, so as I understand I should use System.net.sockets to do this.
But the problem is in the VB application multiple sockets are created by using the index feature of the winsock . example
Load Socket(isocket)
where isocket is an integer variable that is incremented each time, for a new connection request.
So how do I do the same, ie. open multiple sockets in vb.net?

I wish to communicate over usb in vb.net i realize i might need to use openfile windows api or createfile windows api but im doing a generic mouse driver which should be miles simpler to do since microsoft and usb.org already have the report descriptors available so all i want to do is just send data to the device directly using my program.

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.

If I control both applications, what is the best way to communicate between 2 exe's written in VB.Net. For example, I want to drop an XML file from one app, and pick it up with the other, but I do not want poll for the file. I've heard of named pipes, but I found it was complicated. What's the most effecient way to do this?

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

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.

I have a program that opens the command prompt and sends commands. I need to leave the first CMD open, open ANOTHER cmd and send more commands to the second one.
Then I do some processing and can close them both. How can I open more than one, and how do I refer to the first or second one?

I'm coding a restaurant program where every table, server and guest is a different object - Is there a right way of getting objects to communicate with each other?For example, one server might have 5 table objects, each table might have 2 guest objects. Is there a way to neatly tie all this information together. If a guest moves to a different table I have to change a large number of variables (number of guests served by server, table set to empty, new table sat...etc etc.)?

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.

What is an easy to implement way to communicate between 2 vb.net (3.5) form applications that are running on the same machine?
The current problem is that in each program a user needs to be logged into to use. If the user is logged into one, and clicks a button to launch another, it should pass who is logged in so they do not need to log in again in the second program.
