Here's a question that I've not been able to get a definitive answer to.
Creating an STA object (such as a typical VB6 object) and assigning to the
ASP Session store is a bad thing.
It's a bad thing because it forces IIS to affiliate the Session with the
Thread on which the STA object is created.
This means all subsequent requests for that session can only be handled by
that worker thread and can therefore result it in poor performance as
requests queue up to access the thread they are affiliated with.
My question(s) is/are this:
Is this affilation now set in stone for the life time of the session?
Does removing the STA object from the session remove the affiliation or is
IIS/ASP just not that clever?
i built an adminisrator page that needs to be under SSL,when its under SSL i cant use the Session object so i cant really know if he is an administrator. i can make a unique password to the page but the problem is its a page that reloaded often to show different things & then each time he will need to enter the password, a little bit annowing.
I am writing a new asp.net program. Here in, the user has to click on a button on a web page, and a new excel sheet should open up.
I could do it successfully using Office 2k3 PIA's for the click event handler for the button. Then I decided to create a new thread and complete the process of creating an excel sheet in the new thread itself.
But I am getting the following error.
An unhandled exception of type 'System.UnauthorizedAccessException' occurred in Unknown Module.
Additional information: Access is denied
But, the code executes successfully when i remove the thread and directly code it in the click event handler for the asp button.
What might be the problem?? How can I give access permission to the thread?? Should set some permission in the Internet Information Services Manager.
Does the issue posted in http://support.microsoft.com/?kbid=243543 apply to IIS 5.0 and IIS 6.0 whereby storing objects in session or application objects causes thread affinity thus removing all benefit of a thread pool
Is there an explanation somewhere as to how IIS6 determins how many ASP threads its actually going to use?I have configured IIS6 to have 20 threads (ASPProcessorThreadMAX) but it uses them all.
I am using the MACT test tool to stress test and with 50 concurrent users I quite often see only a single ASP thread being used the other 49 are on the Requests Queued. The Request Wait Time in Perfmon can be averaging around 5 or 6 seconds and there is plenty of spare CPU.
The application quite often has long running queries(15 to 20 seconds per request)and rather than use another thread IIS will quite often just keep ticking along with the threads its using with the result that the Request Wait Time can jump significantly.
I am working on a web store that has been having some problem with memory leakage; so I am working thought my code and I am just following up on an issue I have discovered I don’t know the answer to. I am self taught so if my question looks stupid please bear with me.
Set objMyObject = Server.CreateObject(Name)
Do I need to use the objMyObject.Close? before the Set objMyObject = Nothing is called? Could someone please explain or expand as to when and why I use the .Close call.
I created a class ImageEdit to help me get more from an image component i'm using. The class has few private properties and public methods. One of the methods is the Load() method which requires 1 parameter: the complete path to the image.
As long as i have the class definition included in the page and create and instance of the class on a page and use the properties and methods, everything is fine. The problem arises when i try to set this instance in a session variable like so:
set session("imageedit") = new ImageEdit
And this also seems to work fine as long as i'm still executing the code on the same page the new object has been created on. However... i can not get this object to work on any other page. Weather i use this: Code:
This is a strange thing. My Session object is expiring when the page is refreshed.This is happening in just one partiular page. Rest of the pages are working fine
Public Property Let TableName (sNewTableName) if sNewTableName <> "" Then sTableName = sNewTableName end if End Property
Public Property Get TableName () TableName = sTableName End property
.....
Then in a login page i do this
Set Session("cart") = New CShoppingCart
so now, the cart is a session object that can be called from every page in this session BUT.... when i do this in a different page:
Response.Write Session("cart").TableName
I get an asp error (Erreur d'exécution Microsoft VBScript (0x800A01B6) )saying this is not a supported method (the error is actually in french! i can paste it if u want)
The object seems to be valid (IsNull return false and IsObject returns true) but i cannot invoke its methods and read its properties ....
I would like to be able to get the type of object that a session variable contains (for example, determine whether it is a string, integer, single precision floating point, ADODB.Recordset, etc...)
I need to know this for a ASP <----> ASP.NET session management script I am writing. I would like to be able just to copy strings and numbers. I already have code that does this, but I don't want my script to blow up when it finds a recordset in the session object.Is there any easy way to detect the object type in ASP?
I have a session object Session("login") whereas I need to extend the time on this to 1 hour, instead of the default 20 minutes. After initializing Session("login"), how would I change the timeout value?
I'm wondering where the data is stored for Session objects. Is it passed to the browser, and then passed back to the server during page requests? Or, is the Session data always on the server, and the browser simply passes the server it's unique session id?
I am putting the thread details into the Thread_Table table, and so creating a new record in that table. THen I need to create a new post in the Post_Table, and need to pass it the ThreadID that I just created in the Thread_Table. Code:
I'm completely lost as to what's causing this error on my browser. When i try to view my site with Internet Explorer my asp pages show nothing but the below error:
Session object error 'ASP 0102 : 80004005'
The problem is we are still getting orders and the tech support from our hosting company says he's not getting the error so it seems i'm the only one getting it, to make it stranger if i look at my site using Mozilla Firefox i don't get any error. This seems to conflict with the fact that asp is a server side script and so the browser shouldn't make any difference to asp errors but in my case it does?
What's stranger still is if i try to log into my sites Helm control panel i get a similar asp error but this time no matter what browser i use i get the same error and can't log in.
If anyone has any idea what could be causing this or more importantly what i can do to fix it I'd be very grateful to hear about it. I hadn't changed anything on my site or my browser when this error started appearing about 2 days ago and the tech support say if they aren't getting the error their end they can't fix it so I've no idea what to do.
I have an xml file, which is to be updated by an asp script (vbs) when users are submitting forms from their browsers. Now I wonder if there is anything that stops the following to occur: Code:
I am using ASP + IIS + MS access, when running the following codes:
set Conn=Server.CREATEOBJECT("ADODB.CONNECTION") conn.open "DRIVER={Microsoft Access Driver (*.mdb)}; " & Server.MapPath("db.mdb")
The following erorr is show:
General error Unable to open registry key 'Temporary (volatile) Jet DSN for process 0x508 Thread 0x634 DBC 0x2181024 Jet'.
I have shared the MS knowledge base and try to grant the modify Permissions to IUSR_SERVER on the folder that holding the database, and set the script authority in IIS, the error is still exist. If I create a system DNS for that Access file and modify the second code as ...
conn.Open "AKmobile"
Another error is show:

But there is no problem when conencting with MS SQL Server.

I'll admit my ASP skills are very rusty, and come seeking help.
I'm currently using a dictionary object to store a multi-dimensional array.
I want to pass this dictionary object to an object, which holds an array of dictionary objects.
However I'm finding that the array is not getting set, thus I'm having great issue with dynamically resizing the object's property for every new dictionary object I'm adding.
I have a VC++ COM object which fires an event. I've written VB EXE apps against it and they receive the event notification.
I've now built a simple VB COM object which uses the VC++ COM object internally.
My question is, assuming the ASP page which loads the object does not immediately exit, will the VB COM object be able to receive the events from the internal object?
We are using .net 1.1 on windows 2003 server. This is we are facing in our production server.
When we are doing the load testing we are getting the bellow error. While the load testing this error is not coming frequently. When we run 20 threads for 3 mins we are getting this error message 2 or 3 times. But this line of code is executed by all the threads. Code:
I want to open a recordset object on an .asp page. When I open the recordset I would like to use a stored procedure that expects a parameter to be passed for the stored procedure. I will then use the recordset to loop thru the recordset, update values from the recordset and then update the database by passing parmeters to another stored procedure.
I would like to use the recordset object but can it be used to pass a parameter to a stored procedure? Do I need to use a command object to open the records instead in order to pass the parameter to a stored procedure?
A three-tier user authentication system was running without a problem for almost a year and now is suddenly dysfunctional. We don't know of any changes to any of the servers. It's quite maddening. The details:
1) We know the COM+ app is instanced on the COM+ server (Win 2000). The component graphic spins when CreateObject is called.
2) The proxy is installed on an IIS server (Win 2000) with delivers the interface, written in ASP, to the client PC.
3) These are the error messages displayed when a method of DAMS is called: Code:
I have a site that I'm trying to migrate to ASP.NET from ASP, and the foremost stumbling block I'm hitting is session state between the ASP and ASP.NET applications. In order to access this information, I'm doing a HttpWebRequest from the ASP.NET side into an .asp page, passing the session name on the get in order to request it from the ASP side and write it back to the response stream, giving ASP.NET access to it. Of course I change sessions each time I make the call from the ASP.NET side.
Soooooo, I'm thinking to myself, "Self, shouldn't you be able to fake out the server by getting the session cookie from the initial usage of the asp, pass that data to the ASP.NET, and use that to send a request back the ASP side under the appropriate session?"
From a real high level, I enter the site via a .asp page. This page in turn calls .aspx page from within a frame ......
I want to create an administration page which lists all the current users who are on the site at the moment.
I know coldfusion has this feature built in using the SessionTracker class... does ASP have something similar? If not... is there any way I can just iterate through all the session files on the server...?
I have a site developed using ASP, but each page I enter has a different session id when accessing the site using the domain name of the site. When accessing the site from my network and using the internal IP address, it is OK. Any ideas?
I have one column in my access database named 'picture'. I uploaded the pictures in the database using OLE Object. Now I want to have a picture of an employe in my ASP form. It gives me an error. The page works without that code-line where picture is mentioned. Code:
