php to asp.net convertion

I am answering to get this out of the unanswered question list. The answer is no, unless you're paying, no-one is going to rewrite all this code using ASP.NET. You'd do better to just define the task and write it from scratch, PHP sucks.

this php code from http://anantgarg.com/2009/05/13/gmail-facebook-style-jquery-chat/[^]

The convert php to c#/vb not too tough but here problem will not solve from this conversion. here added some js & jquery file with php file.

yet...Keep Try!!

The code as after conversion ..(its not my code)

//////////////// problem in this line
items = items + "\"s\":\"0\",\"f\":\"{" + message.userfrom.ToString() + "}\",\"m\":\"{" + message.message + "}\"";

/////////////////////////////////////////////

In the Solution 5 the problem is here. The Json Message was not correct so the user cannot receive messages

try using this line

items = items + "{\"s\": \"0\",\"f\": \"" + message.userfrom.ToString() + "\",\"m\": \"" + message.message + "\"}, ";

Thanks.

I try to use this code, but i am getting the error on SendChat Method

string to = Request["to"]; // Assign POST FORM 'To' value to $to value}

((ArrayList)(Session["openChatBoxes"]))[getIndexOf(((ArrayList)(Session["openChatBoxes"])), Request["to"])] = DateTime.Now.ToString("Y-m-d H:i:s");


This line was getting this error

Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index


Can anyone guide me to fix this error

I think that[^] is you[^] (So you have two accounts?). Why do you still want that code after 2 years?

Anyway check this
