Multiple User application - help required.

I am hoping that someone can guide me through the solution to the following 
question.

I have a disconnected ADO recordset that uses a join between two tables, 
this recordset is then used to populate a form. A TDBNavigator control 
allows the user to move through the recordset and delete or edit a record. I 
should say that there are TDBLookupComboBoxes that hold values. Not sure if 
this makes a different to the task.

I would like to allow for multiple users so I will have to cater for a user 
either deleting or editing a record that another user may have say edited.

So far I have used:
a) the BeforePost event to check all the values are correct.
b) the OnPostError event to try and manage the error, eg. the record has 
been edited.

I found some code written by Brian Bushay that allow the application to 
write over the users values with the ones that the other user has posted.
    ADODataSet1.RecordSet.ReSync(adAffectCurrent, adResyncAllValues);
    ADODataSet1.UpdateCursorPos;
    ADODataSet1.Cancel;
    Action := daAbort;

This is OK but how do you manage a deleted record?

I would like to inform the user of the changes that the user has made and 
let them make the decision to accept heir changes or write over the new 
values with theirs. How can this be done?

Any comment gratefully accepted.

Multiple applications and users
We have multiple applications (100+) and lots of users. Some users need access to multiple applications. We have a central administration application, that handles all user management. We use membership, role and profile providers. Question: Should I create an record in the aspnet_Applications for each application, or is it better to use a central single "domain" name in the aspnet_applications table and use the aspnet_Roles table to store the applications, the user has access to?Johan TheunissenMCPD, MCSE, MCTS BizTalk 2006==============================Please mark the most he...

User control for multiple applications
I am trying to build a user control which I can use across multiple applications - All the applications I am developing will have the same header, so naturally I have created a user control for this. As far as I understand, you need to create a strong key for the user control and add the dll to the GAC, and add a reference to the machine.config file. I have read an article on this but have not been able to get it to work:(http://www.ondotnet.com/pub/a/dotnet/excerpt/aspdotnetian_6/index4.html). The error occurs when I try to register the usercontrol on the .aspx page, eg. <%@ Regis...

Applications That Do Not Require User Interaction
My major client operates out of a secure facility such that I only have access to their 35 or so machines 7:00 am to 5:00 pm (07:00 to 17:00) Monday through Friday. Consequently routine maintenance is a tough thing to do. Most of the users turn off their machines every evening so leaving them running or asking the users to leave them on one night a week or something like that is a non-starter. To deal with this I have put together a framework that hides the "Turn Off Computer" button and replaces it with a similar looking button that actuates my "system" ...

User Application load-balancing + fault tolerance ; User Application scaleability
Hello all, Please bare with these rather naive questions regarding the U.A. I'm trying to confirm/infirm some possibilities for a customer and I cannot find all the information I'd need in the Novell documentation. Is there any other way to do load balancing + fault tolerance with U.A. beyond using JBoss clustering ? I suppose one way would be to have two completely distinct U.A. installs (each with its own DB) and do load-balancing through a dedicated device (web gateway/proxy). Any other idea ? I highly suspect running two separate instances of the U.A. using the same...

Single user with access to multiple applications
Hi There I am implimenting the .NET 2.0 Membership system within a set of applications I am working on.  I am using the SqlMembershipProvider. I want to know if it is possible to give 1 user account access to multiple applications.  Looking at the DB schema, there seems to be a 1 to 1 membership between a User and an Application. Ideally I want a 1 to Many relationship.  This would affectively allow us to grant an existing user access to new applications as they are developed.  It would also allow a user to log in, and be presented with a list of Applications they...

Mapping a single user to multiple applications
I want to implement a single user sign on system for several web applications using the membership provider in asp.net 2.0 but having examined the schema of the generated schema for the database I have found a problem. The primary key in the aspnet_users table is user_id as it is in the aspnet_membership table. This makes it difficult for a user to use the same login for several applications. I know it is possible to apply the same application name to the web.config file in several sites so that the user list applies across applications. The only problem with this is that&nb...

Shared User Controls Between multiple Web Applications
Hi, Just wondering if it is possible to have design-time shared user controls.  E.g.  I have followed the process to setup a 'base' web project that contains a number of shared user controls and configured IIS.  I then use these user controls in a number of web application projects.  This works fine as per http://support.microsoft.com/kb/825996.  However the limitation is that you need to code the registering and using of the user controls rather than drag and drop. I want to know if it is possible to add these user controls(through vss sharing) to each web ap...
