Named pipes might be one you want. They are kind of like shared files but not written to disk and you won't have access problems. &nbsp;VS help has examples.

i am a beginner can there be an unsecured more easy code<br />
just for testing<br />
<br />
ex: if i change a value of text box on one computer it should reflect on other computer<br />
&nbsp;
</div>


<div>
'NamedPipeServerStream' not defined error is coming at running the above program
</div>


<div>
That happens when you run it or compile it, and what line?
</div>


<div>
when i press f5 on line no 19
</div>


<div>
Dim pipeServer As New NamedPipeServerStream(&quot;tes<wbr />tpipe&quot;, _<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; PipeDirection.InOut, numThreads)<br />
&nbsp;<br />

</div>


<div>
a green line is also coming on <br />
imports system.io.pipes
</div>


<div>
You might have to add a project reference to the System.Core assembly.
</div>


<div>
it is not there in refrences<br />
i have searched everywhere<br />

</div>


<div>
Sorry, my mistake. &nbsp;I didn't realize the named pipe classes are only available in the latest framework, which I think means VS 2008 is required. &nbsp;Sockets or remoting would be some other options, but neither is trivial. &nbsp;I'd opt for the file with polling.
</div>


<div>
plz can u tell me one of the techniques <br />
i understand rmi and all
</div>


<div>
but i have never implemented on vb.net can u suggest some examples<br />

</div>


<div>
how can i query sql server persistantly to retrieve the updated data from the database
</div>


<div>
Polling a database would be a good alternative. &nbsp;You don't have Visual Studio documentation? &nbsp;It will have examples. &nbsp;You would use SqlCommand to run a query, and Timer to periodically invoke the query. &nbsp;Or I imagine google on SqlCommand for one example and Windows.Forms.Timer would get you the other.

Visual Basic .NET (VB.NET) is an object-oriented programming language implemented on the .NET framework, but also supported on other platforms such as Mono and Silverlight. Microsoft launched VB.NET as the successor to the Visual Basic language. Though it is similar in syntax to  Visual Basic pre-2002, it is not the same technology,

Office Productivity refers both to the act of being productive and efficient in an office or professional environment, as well as the software applications used to "produce" information. This includes the development of professional skills, creating work processes, and almost any program used to create or modify a document, image, audio or video clip. However, business application suites such as Microsoft Office, which include word processing, spreadsheet and presentation programs, are typically called productivity software, as contrasted with a "utility program," such as a file manager, which is used to organize files and folders on the computer. Many office- and business-oriented groups of programs are organized into suites.

File sharing is the practice of distributing or providing access to digital media, such as computer programs, multimedia (audio, images and video), documents or electronic books. Common methods of storage, transmission and dispersion include manual sharing utilizing removable media, centralized servers on computer networks, World Wide Web-based hyperlinked documents, distributed peer-to-peer networking (P2P) and cloud-based file syncing.
