<br />
con = new SqlConnection(ConfigurationManager.ConnectionString["conn"].ConnectionString);<br />
This code contain two 'ConnectionString', So error appears does not contain a definition for 'ConnectionString'
it's right:
<br />
con = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);<br />

very easy.
Don't use the ConnectionStrings.
Use ConfigurationManager.AppConfig["myconn1"]

Dear All,
I have a web application from which I need to send an UDP datagram.
When I send the data through Synchronous mode it is working fine.
When I use asynchronous operation it is throwing the below error:
"A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied "
The code used is:
Asynchronous:
senderOfMessage = new UdpClient();
IPEndPoint remoteEndPoint = new IPEndPoint(IPAddress.Parse(serverIP), Convert.ToInt32(serverPort));
byte[] message = ASCIIEncoding.ASCII.GetBytes("Test Message");
senderOfMessage.BeginSend(message, message.Length, new AsyncCallback(OnSend), remoteEndPoint);
Synchronous:
Kindly help me to get rid of this issue.
Thanks a lot in advance.
Best Regards,
M. J. Jaya Chitra

What are you trying to achieve by using UDP in a ASP.NET application?

Dear Navaneeth,
I have to send a message to a windows service, the windows service in turn sends a message to another external application which is not developed in .Net.
For sending the message to external application it used the UDP, so the same UDP is used o receive the message from the web application too in the window service.
Best Regards,

You can write a page that takes an id and feeds the excel file to the client from your DB.

You're not adding any of the parameters to the command object
something like
cmd.Parameters.Add(sp1);
(Look it up - I don't have an example in front of me - but that's the issue here - upir cmd object doesn't know about the parameters.

I am sorry, but your question makes no sense. Try to rephrase it.
|
|
|
|
|
Is this a question ? If it is, is it a 'I did some research and tried this but it doesn't work' question, or an 'I'm a dumbass, do my job for me' question ?

I am developing an ASP.NET application and i want to prevent the right click option for a particular page .How can it be achieved is there any javascript.
Thanx in advance.

Just Add this line in body tag
oncontextmenu="return false;"
Fastrythem

<HTML>
<script language="javascript">
function preventEvt(evt)
{
evt.returnValue = false;
if( evt.preventDefault ) evt.preventDefault();
return false;
}
</script>
<BODY oncontextmenu="return preventEvt(event)" onmousedown="return preventEvt(event)">
</BODY>
</HTML>
This code can works in IE and Firefox, but no way in Opera

There are ways to convince an ignorant client that you did this, but I guarantee you that I can circumvent all of them, if I really wanted to right click on your web page.

What exactly are you trying to prevent?
