Aspx use same Class Library instance ??

[oma]

hi,

i'm using aspx with a class library project.

Problem:
Every user uses the same instance of the class library project, so i get errors like (Object not set to an instance of an object, although it is set correct, but the other user already destroyed it, because he didn't need it anymore, etc.). I get this errors only if i simulate 2 Users. With one User all works fine. But if the second one want to use the class library then it crashes.

So how can i tell the webservices to use everytime a new instance of the VB Class Library ?
(At the moment i'm using in the asp.net pages something like that: Dim ocontrol as New DllProject.Dllclass() and then Dim dummystring as String = ocontrol.checku("asas","asas") )

Or need i to change something in the VBProject ?

Thanks in advance.

I don't think that the problem is a shared instance. Your code creates a new instance before it uses it so even if one user shared the same instance and that instance was destroyed then it would recreate it. Are you putting this code in a module or a page? Module level code 'may' be shared across multiple sesssions but page variables aren't.

Post either part of your project or the exact code giving you trouble. Also the method you are using to test with multiple users.

i tested it and the problem seems to be ado. I upgraded the project and use the old ado with recordsets:

Public con As ADODB.Connection
Public odbpath As String

Sub dbopen(ByVal cdbpath As String)
con = CreateObject("ADODB.Connection")
con.Open("Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=" & odbpath & ";Jet OLEDBatabase Password=")
End Sub

Sub dbclose()
con.Close()
con = Nothing
End Sub

Everytime there is a DB Access => Error

So i will try to make a workaround.
