closing objects after returning value in function ??

[dotnettester]

Hi,

I am maintaining some code and I see in some functions..

Function myFunction

set someobj = Server.CreateObject("MYOBJ")
.....
....
set myFunction = "somedataToReturn"
set someobj = nothing

End Function

 

[dotnettester]

sorry, my question is, is it valid to close an object after the return
statement and would it work?

I believe both Dave and I answered the question. Nothing after the End
statement is executed.

Oops. Ignore my previous. I thought we were still on the Response.End
statement.

There is no "return" statement in vbscript. All statements in a procedure
will be executed until the statement that ends the procedure is executed,
unless an Exit <function|sub> statement is encountered.

So in this example "set someobj = nothing" will be executed. It's easy
enough to test this:

<%
dim globalvar
globalvar="initial value"
function changevar()
changevar = "I ran"
globalvar="new value"
end function
response.write changevar()
response.write "<BR>" & globalvar
%>

Actually, this question is slightly different from the Response.End
question. In this case, dotnettester is asking whether the statements after
a function return value assignment are processed. Specifically, does
"someobj" get deallocated in the above example? The answer is yes. Here's a
proof of concept demonstrating the behavior:

<%
Option Explicit
Function Foo(bar)
Foo = 1
Response.Write "Hello World!"
End Function
Response.Write "<br>Foo(0):" & Foo(0)
%>

To add to what Bob said, while there is no return statement in VBScript,
there is in JScript. It is also worth noting that the return statement in
JScript behaves as you would expect. That is, it exits the function
immediately. Therefore, the JScript counterpart to these examples would NOT
execute the statements following the return value assignment. The template
for JScript would look like this:

function foo(bar){
var retVal;
var myobj;
myobj = new ActiveXObject("My.Object");
retval = myobj.property;
myobj = null;
return retVal;
}

Thanks all.
