Hi ,

I am doing the conversion from php chat application to asp.net chat application.
In php chat application work fine,

so i am converting now, the problem i am facing from php is, they used some array with session variable i dont know the correct equalent in Asp.net. this is the code

in php:

PHP

$_SESSION['openChatBoxes'][$chat['from']] = "from value";

in .net i tried:

VB

DirectCast((Session("openChatBoxes")), ArrayList)(getIndexOf(DirectCast((Session("openChatBoxes")), ArrayList), "fromname")) = "messagecontent"

Its shows the error message for me as follows

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

Please help me. its very urgent

Solution 1

in .net I think you should remove 1 from index. see the updated line here

DirectCast((Session("openChatBoxes")), ArrayList)(getIndexOf(DirectCast((Session("openChatBoxes")), ArrayList), "fromname") - 1) = "messagecontent"

Hope this will work.

This is not an answer. Further expecting a code is not the way it works here. You need to make effort and share what you have done.
