The rexec protocol works as following :
Client makes TCP connection to REXEC port (512).
Client sends TCP port number (decimal ascii, null-terminated) of port. If the first byte is a NULL, then server won't make any stderr connection
Server makes TCP connection to client's port
Client sends target username (null-terminated).
Client sends target password, NULL, remote command, NULL, and then command's stdin, followed by a FIN.
Server sends one null byte (=no error), or a non-null byte, followed by error message(s).
Server sends output of command.
Server sends FINs on stdout, stderr connections.

If you have done any Socket programming I suggest you go through examples provided by Microsoft.
Once you familiar with creating sockets and tcp/udp protcols (conection based and connectionless) and sending and receiving, implementing rexec is simple.

Thanks for your updates.
I am not aware of socket programming. Some of my friends told me, through
the socket programmin we can tranfer the file but they don't know  how to
execute the remote system (Like Solaris,Linux) files. Please guide me.
If you provide some sample code that will be very helpful for me.
Thanks,
Tharma

hello

Are you writing a VB.Net windows form application, or are you using VB.Net with ASP.Net?

hello
i'm using vb.net with asp.net.
plz help me.
i'm stuck becoz of this problem
|
|
|
|
|
in the code behind page:
..
Private Sub btnDelete_Init(...) Handles btnDelete.Init
btnDelete.Attributes.Add("onclick", "return confirmDelete();")
End Sub
...
on the aspx page:
..
<script language="javascript" type="text/javascript">
function confirmDelete() {
var strMessage = 'Are you sure you want to Delete this record?');
return window.confirm(strMessage);
}
</script>
...
This script will provide a confirm dialog which asks the user is they are sure they want to delete this record, and if the user has selected 'Ok' then the script will submit the page back to the server and you can use the btnDelete_Click event to process the action. If the user selects 'Cancel' from the prompt, the page will not post back.
Hope that helps.

Need help on this.. i search in search engineer but all gave me playback of video file or Capture picture shot.
Any pro here know how to record video or have the program?
|
|
|
|
|
You have three options, at least:
1) Buy an OCX and read the code samples it come along with (i.e. Pegasus Capture Pro, or the Viscom I remember)
2) Install, read Microsoft DirectX SDK and browse the sample code provided
3) Write your own from scratch based on VfW (old, tough and I think pointless).

i haf try DirectX, it only help to capture photo, play audio and video files. But not Record VIDEO.
|
|
|
|
|
It does capture video to AVI or WMV. There samples available on MSDN Library as well.
But I suggest you also to have a look at the implementation presented on this site about capturing video with a DirectX class.
Just use the search function on the code project and you'll get plenty of ideas.
Like:
http://www.codeproject.com/cs/media/directxcapture.asp (it's C# but you can simply use the DLL in VB.NET)
This one will give you details about DirectX video capture:
http://www.codeproject.com/directx/MPEG2_Capture_Device.asp
Others are available.

Any particular reason why you used OleDb rather than the SqlDataAdapeter?
