can Session.Contents can be a string array?

[Bart Plessers \(artabel\)]

Hello,

My script builds a list of files in a folder.
These files are stored in an 2-dimensional array, called "a_files".

To speed up the script, I don't want the filelist everytime being read on
the server.
Therefore I wanted to send the contents of a_files to a session variable.

However, with
Session.Contents("sFiles") = a_files

I get the following error message:
***********************
Response object error 'ASP 0106 : 80020005'
Type Mismatch
?
An unhandled data type was encountered.
***********************

Is it impossible to store an array to a session var?
Is there another way to store the array somewhere in memory so it has not to
be rebuild everytime?

Do this:
Session("sFiles") = a_files

Yes, you can.<%
Dim x(2)
x(0) = "a"
x(1) = "b"
x(2) = "c"

Session("arr") = x

Response.write Session("arr")(0)
Response.write Session("arr")(1)
Response.write Session("arr")(2)
%>

What is the rest of your code?

be rebuild everytime?

A database is another option.

hmm,
you build the array in memory.

I have build the array in code:

'**********************************
Dim a_files()
i_dim = 3 'geeft het aantal gegevens aan per j in de array. Opgelet, indien
4 gegevens nodig, dan
i_name = 0 'gives posistion in array
i_size = 1 'gives posistion in array
i_type = 2 'gives posistion in array
i_date = 3 'gives posistion in array

j = 0
For each oFile in oFiles
ReDim Preserve a_files(i_dim,j)
a_files(i_name,j) = oFile.Name
a_files(i_size,j) = oFile.Size
a_files(i_type,j) = oFile.Type
a_files(i_date,j) = oFile.DateLastModified
j = j + 1
Next
'**********************************


Then I want to pass the a_files() to a session string



Can this also be done?
Syntax if?

An array is an array.
You can store it as an array in a session variable.

do you have any idea why i get the error

***********************
Response object error 'ASP 0106 : 80020005'
Type Mismatch
?
An unhandled data type was encountered.
***********************

Session.Contents("sFiles") = a_files


Do I have do Dim the sFiles before?

I don't know. I've tried your code and do not get the error. Here is what I
tried:

Dim a_files()
i_dim = 3 'geeft het aantal gegevens aan per j in de array. Opgelet, indien
4 gegevens nodig, dan
i_name = 0 'gives posistion in array
i_size = 1 'gives posistion in array
i_type = 2 'gives posistion in array
i_date = 3 'gives posistion in array
set fso=Server.CreateObject("scripting.filesystemobject")
set oFldr = fso.GetFolder(server.MapPath("."))
set oFiles = oFldr.Files
j = 0
For each oFile in oFiles
ReDim Preserve a_files(i_dim,j)
a_files(i_name,j) = oFile.Name
a_files(i_size,j) = oFile.Size
a_files(i_type,j) = oFile.Type
a_files(i_date,j) = oFile.DateLastModified
j = j + 1
Next


Session.contents("arr") = a_files
for i = 0 to ubound(session("arr"),2)
for j = 0 to ubound(session("arr"),1)
Response.Write session("arr")(j,i) & "<BR>"
next
next

It seems like you don't have an array. Have you used IsArray to verify that
a_files is an array?

bob,


STUPID ME!!!!!!!!!

sorry to bother you with this.
The problem was that -for debugging- I had included a file "_debug.asp"
In this file, there was a line :

response.write(session("SFiles"))

just becaus SFiles was an array, the response.write could not handle
this.......


anyway,
your code pointed me to reconstruct the array, and not write it itself, so
it was very helpfull!

sorry to bother you
thanx again,

bartp
