Maybe you could attach the files in .zip format as I think more members have winzip then winrar.
I only have winzip.

1:i found error in client class the code is client.Send(buffer, wd, Sockets.SocketFlags.None)
2: in server class error is wd = Client.Receive(buffer, PacketSize, Sockets.SocketFlags.None)
if anyone have solution of these problem plz contact me

[AkkeDaBest]

but I have this error and I cannot see any thing wrong with that line

wd = Client.Receive(buffer, PacketSize, Sockets.SocketFlags.None)

I have the same problem.

And I use visual studio 2008

What could i change them to?

Hello,
It's been more than 2 years since I posted that code.
It's easier to do the same using remoting if you ask me now.
It takes fewer lines of code...and is much more simpler.

1.)Setup a remoting server
2.) set a remoting client
3.) In the remoting server class,make a function to take screenshot of the server and return it as a memorystream.
4.)In the remoting client,call that server function and display the picture on a picturebox. (use a timer to do it repeatedly)

It's that simple. If you have no clue about what I'm talking about....trust me and follow these steps...
1.) Search for "remoting in vb.net" on google....find how to do it...
2.) Search for "screenshot vb.net" ....you'll get the code for it somewhere online
3.) Use a timer on the remoting client and call the server's screenshot function repeatedly
4.) combine those two and rock it!! :-) (This is the best solution for beginners...not for people who ask for performance.This will not work well over the internet...it will work best only through LAN)


I'd love to help you with the code....but Unfortunately,I don't have the time to do the code and post it right now....but I will soon when I can....

Trust and try the steps mentioned above.....and Success is certainly yours!!!

Hope that helps....

hi Dear
do you know something if i want to develop same applicatoin for web like msn messanger multiple users can view eachother desktop i think it will be interesting.

For anyone who is interested in improving the speed of such a program - you should look into how programs like VNC work (VNC is a remote computer control program - www.realvnc.com). From Wikipedia's VNC article:

The server sends small rectangles of the framebuffer to the client. In its simplest form, the VNC protocol can use a lot of bandwidth, so various methods have been devised to reduce the communication overhead. For example, there are various encodings (methods to determine the most efficient way to transfer these rectangles). The VNC protocol allows the client and server to negotiate which encoding will be used. The simplest encoding, which is supported by all clients and servers, is the raw encoding where pixel data is sent in left-to-right scanline order, and after the original full screen has been transmitted, only transfers rectangles that change. This encoding works very well if only a small portion of the screen changes from one frame to the next (like a mouse pointer moving across a desktop, or text being written at the cursor), but bandwidth demands get very high if a lot of pixels change at the same time, such as when scrolling a window or viewing full-screen video.

will it run to vb6??

[alphacore]

how can i view the code pls..

[paki42o]

i love tht code can i have in vb6 same code???

[cctvofnj]

Hello i gotyour code a while back i been playing with it and think its awesome do you think one day you will make a newer ver of this one. maybe add a new opition in it like what teamviewer is doing instead of putting in ip addresses can put in like numbers or something but still can do the same thing? if so please let me know thank you.....

[oliv7836]

i've just downloaded it :-) Will try it out soon ...!
