View 1 RepliesC# - Restrict Same User To Login From Different Machines
Jun 8, 2012I have a ASP.Net Web application hosted on a server. I want to restrict same user to login on different machines over the network connection but with certain conditions to be satisfied. So I thought of adding three new columns to the User table so that we can track if same user is logged in on same or different machines.
Those columns are like :
IsLoggedIn : To check if the particular user is already logged in or not.
SessionID : To check if the same user instance is opened.
IPAddress : To check if the same user is on same or different PCs.
This should satisfy some of the below conditions, but it fails to satisfy some of them. Conditions are as follows :
Both computers are on the same LAN.
Each computer is accessing the application over the internet from different locations.
Each computer is accessing the application over the internet from the same location.
Some of the application hosted which means that IP address alone is not sufficient to distinguish different computers.
Some users just close the browser without logging out. So sessions may not be ended at this situation.
How to accomplish all these conditions to satisfy with my application ?
Mainly 4th and the 5th .

View 3 RepliesOpening An Image In Vb To Send Into A Database - Asp.Net
Apr 22, 2009I'm currently patching an asp.net program where I need to be able to send an image to an SQL Server 2005 DB. It works fine when I use the asp:fileupload control, but the trick is that when the user deletes the image, I'm supposed to replace it with an image from the server saying "empty", in code-behind. I know how to open, use and save text files in vb, but I can't find any information anywhere on how to open an image / binary file in a similar manner so that I can use it as an sql-parameter on the update query. Below is an example of how easy it is to use a file from the fileupload control.

View 4 RepliesUser Data - SQLCE Files - One Database With Multiple User On PC
Mar 3, 2010I'm designing a PC-based app that has a little local database. I'm using VB.NET with SQL Server Compact Edition. The user will only ever have access to one database file, because it's all about storing a user specific data. However I'm thinking of the situation where there could be multiple users that access the PC, each with their own Windows account. So ideally I'd need separate database files for each User.
I'm not sure how to implement this. I was hoping to deploy the 'empty' database as a ClickOnce deployment, but I can't see how I can have a database per user doing this. Also I'm not sure where to store the database files anyway. perhaps in MyDocuments for each user? Or perhaps I need to stick to just one database, but add a 'User' column into every table, so it can hold data for every user. I didn't want to do this though - because I wanted to keep the nice separation between the data offered by physically separate files.
