Socket : Tcp Protocol : Message not instantly delivered.

Posted By:      Posted Date: October 12, 2010    Points: 0   Category :.NET Framework


Now that I have solved the problem from my previous issue, I'd like some information or explanation regarding the workings of the Socket on the TCP protocol. I'm aware that the Sockets implement the Naggle algorithm to prevent the network from beeing flooded by small network packages. However, I'm encountering a strange issue in my client - server architecture:

When I click on the GUI to send out a command to my server, the server reports the data as beeing received, but the reply is not always send back immediatly. Sometimes I need to click the button twice before the reply actually comes back. When I debug the applications and step through everything slow enough, the command is send back on the first time, but when running in release mode the reply is not always send back the first time.

I've disabled the Nagle algorithm, but I still notice that really short commands still get grouped together in a single "message" from the socket. How can I force the socket to immediatly start pumping the data over the network as soon as I've finished writing the data in the socket send buffer ?

Inserting personal error message in ValidationSummary



I am creating a web form that requires a lot of validation. I use many of the validation control in asp.net already like RequiredFieldValidator and CompareValidator. 

My Problem: after my custom validation for the value entered return an error message, and I pressed enter key when the field is empty, my custom error message is overlapped by my ValidationSummary. 

Setting my custom error to visible = false on button click also does not seem to work as it requires for me to enter the value first.

This made me think, is there a way to insert my custom validation inside the ValidationSummary as an error message like for other validation control?

Thanks in advance

UpdatePanel is not a known element - message when upgrading to 1.0 ajax


It worked on one of my old pages.  I change the web.config, renamed all the <asp.

On some aspx page it doesn't recognize the updatepanel.  It only does on one page.  If I create a new aspx page with a different name - then it works.

Should I just create a new web project ajax - then copy all my code into there?  Or is there a way to get those old pages to recognize the new ajax controls?

Very Basic Question - Error message running first page


Hi Everyone,

I am running Windows 7 and I have gone into Control Panel and activated all of the IIS Functions.

The web application I am running was downloaded from the net (and has worked on other machines previously).  Once I downloaded it, I moved it into C:/inetpub/wwwroot/code/main.asp

I am a bit of a novice at this!  But I am hoping someone can point me in the right direction!


I get the following error when I try and run the web application through IE:

"An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error."

(When i click the "click here" button it just goes to the IIS site).


Appreciate any help I can get!

Secure It: WS-Security and Remoting Channel Sinks Give Message-Level Security to Your SOAP Packets


As more organizations adopt XML-based Web Services, the need for message-level security has become evident. WS-Security, now supported in the Microsoft .NET Framework, addresses this need. Using the WS-Security framework, developers can implement channel sinks to intercept Remoting messages as they pass through the .NET Remoting infrastructure. The sink can read the message, change it, and pass it along. During this process, the message can be signed for added security. This article explains how to implement a Remoting channel sink that will modify the Remoting message by including a UserName token in the header, then sign the body using the token.

DIME: Sending Files, Attachments, and SOAP Messages Via Direct Internet Message Encapsulation


Direct Internet Message Encapsulation (DIME) is a new specification for sending and receiving SOAP messages along with additional attachments, like binary files, XML fragments, and even other SOAP messages, using standard transport protocols like HTTP. In this article, the author explains what DIME is and how it differs from MIME encapsulation. A detailed description of the message format and how it is parsed, as well as working with SOAP and extending it with WSDL, is also included.
