I'm looking for a way to allow only one user to access my web form at a time. so that if there is a user using my web page / html form.. then the next user is directed to another page. So only one user is allowed access at any given time .I was hoping there is a way to do this with Application variables.
View Repliesmy form contains two text fields(name, address) and two file field control where user can insert image(photo1 and photo2), i want to insert this data in to ms access when the user submits the form?
this is my code for insert text fields to access data base.but i have no idea about the code for image fields. In my access data base i set photo1 and photo2 as herf (binary data). Code:
We have our web site setup on two seperate servers. They are connected together through a BIG/IP server. I'm not sure how many of you are familiar with BIG/IP (load balancing) but I'll give you a quick explanation:
When a user goes to our site, they hit our BIG/IP server first. This server looks at our two web servers and determines which one has more resources to spare. The BIG/IP then redirects the user to that server, where they are on the rest of the time they are on our site.
So we have two web servers with duplicate web sites running. My problem is I need to run one application object between both servers. Is this possible, or is there a work-around?
I am developing ASP application with complicated login system. There is several group of menu options. Each have form 5 to 15 sub-options.
User can work with any combination of options and sub-options and can see only these menu options which are allowed for him. "Rights rules" are store in SQL Tables and are getting after logon.
Now a questions:
1. what is the best way to store this menu structure (Session object is not allowed because it uses Cookies) ?
2. What is the best way to handle the "rights rules" ?
Below you can find quick links to information about the Application Object. I would write a post like my CDONTS one, but I just don't have time, but when I do, I'll see if I can get one done.

HOW TO: Use the Application Object to Store ASP State
I am trying to get to the application object from a seperate class in my ASP
application and I dont want to pass the object in as the class is inherited
to lots of other classes. So i can have something like the following:
Imports System.Web.UI.WebControls.DataGrid
Namespace Classes.Inheritable
Public MustInherit Class EntityCollection
Implements IDisposable
Private mobjDataConnection As Classes.Databases.DBConnection
Public Sub New(ByVal strSQL As String)
mobjDataConnection = Application("DataConnection")
End sub
The following code exists in a Global.asa file:
----------------------------------------------
<%
Set Application("Thing")=Server.CreateObject("THINGDOER.THINGY")
%>
----------------------------------------------
Will the above code snippet:
create a non-object Application variable named "Thing" & place it in
the Contents collection of the Application object?
-----OR------
create an Application object named "Thing" & place it in the
StaticObjects collection of the Application object?
There seems to be plenty of discussion about caching in the Application Object, however, I cant find any info on what realistic limitations there are and how they are measured.
What are the factors that will limit performance / storage of many individual or single large bits of data with application scope? eg database driven list boxes (that dont require up to the minute data) 10 * 100 options? 100 * 100 options? kb's? megs of info? How much can I cache?
I'm having trouble with the workflow described bellow:
1. Asp page 1 on server A contains an iframe.
2. Asp page 1 submits a form targeted to the iframe, to Asp page 2 on
server B.
3. Asp page 2 runs in the iframe and at some point might decide to submit a
form targeted to the _top frame, to page 3 on Server B.
4. Page 3 loads in the top frame. Code:
Rather than opening and closing a new connection to the database on every page, I have placed that connection into an Application variable. This has worked fine so far.
My issue is that I have a logoff page where it closes that connection.But this means that users who are on the application will not be able to access that connection.The obvious answer is that I don't close the database connection.But my problem is, I would like to eventually close that database connection.
How can I determine if an application variable (not session variable) exists?How can I determine that there are not any users on the application?
My asp application allows a number of users to log into it. Each user has a different type of access level (General User, Manager or Administrator). I want the administrator to be able to see how many other users are logged into the application at a particular time. How can I do this? Would the use of an application object work for this?

We have pretty simple ASP (not ASP.Net) application, which has been running fine on IIS4 and IIS5. It has now been moved to a sever running in the DMZ and managed by a 3rd party. The server is Win2003 and IIS 6.0.

We’re just wondering if there is an ordering online software which has a feature to create a customised user environment (different product and prices for different user) for each login user? We really need that feature for one of our customer.
If it is not available could you please suggest a product that has this feature?

I am currently working on a small asp application. Now I would like to store the complete database connection in the application object. Note I want to store the connection NOT the connectionstring. For that purpose I wrote a small asp include which connects to the dbase and stores the connection object to the application object. However when I use this include in my pages then it doesnt work. What I am doing wrong? Here is the code:
View Replies View RelatedI'm using application variables for a web based sales tracking application. I use the variables for stuff like connection string, database name, etc. I store the values in a asp file that is included in a login page. The assignments are in a procedure that I then call on the login page. This is done everytime a user connects to
the login page.
what's happening to the variables? Are they being overwritten everytime a user accesses the page? I'm not checking for the existence of the variables. I just call the routine everytime the page is accessed. I know the values are shared for all users but, I was wondering if I should check for the existence of variables? Will it free up resources? Should I be using locks?

I am creating a web-based application with ASP and using frames. I wonder how we could trace user's browsing behaviours in this particular domain. That is, I need to know which pages the user has viewed and which pages the user has not yet visited, as this information is essential and will be used to assess their learning paths and progress.
Therefore, my question is that how to create a file which stores information about users' browsing history, i.e. the page the user visited, so that we could use these information to assess users' learning progress, or what is the right means to tackle this requirements?
I have a project where i have to use an html asp application form to insert records into an sql database.

I have created a form with simple fields such as address and phone number. I would like to, in real time, take the value a person puts in for name (ex. John Smith), check a database to see if he is there, then to populate his address fields and phone number to save the user the trouble of typing it in repeatedly.
Any ideas how to go about this? I created a button for the user to "look up" to see if his info is saved but cant seem to get the syntax write. I have written similar code for the information to be put in the database, and it works, just need to retreive it while the user is on the form.
