Session Variable Arrays?

[stsuing]

Is is possible to make a session Variable an Array?

I am putting together a survey and want to store all the answers in a session variable instead of making multiple updates to s database. There are 77 questions on 8 asp pages.

Thanks in advance

Hello stsuing!

Sure it's possible. Here is how to use Session and arrays taken from IIS 5 Documentation (write again, if you don't find it clear enough):


If you store an array in a Session object, you should not attempt to alter the elements of the stored array directly. For example, the following script will not work:

<% Session(&quot;StoredArray&quot(3) = &quot;new value&quot; %>

This is because the Session object is implemented as a collection. The array element StoredArray(3) does not receive the new value. Instead, the value is indexed into the collection, overwriting any information stored at that location.

It is strongly recommended that if you store an array in the Session object, you retrieve a copy of the array before retrieving or changing any of the elements of the array. When you are done with the array, you should store the array in the Session object again so that any changes you made are saved. This is demonstrated in the following example:

---file1.asp---
<%
'Creating and initializing the array
Dim MyArray()
Redim MyArray(5)
MyArray(0) = &quot;hello&quot;
MyArray(1) = &quot;some other string&quot;

'Storing the array in the Session object.
Session(&quot;StoredArray&quot = MyArray

Response.Redirect(&quot;file2.asp&quot
%>

---file2.asp---
<%
'Retrieving the array from the Session Object
'and modifying its second element.
LocalArray = Session(&quot;StoredArray&quot
LocalArray(1) = &quot; there&quot;

'Printing out the string &quot;hello there.&quot;
Response.Write(LocalArray(0)&LocalArray(1))

'Re-storing the array in the Session object.
'This overwrites the values in StoredArray with the new values.
Session(&quot;StoredArray&quot = LocalArray
%>
