Restrict Access To AVI Files?

Aug 7, 2010

I need to create a helpsystem for my work. There's two user types ... common users and admin users. The common user needs to se all stuff except admin stuff - admin must see it all.

I use Camtasia to make screencasts - AVI files, which I need to put in my helpsystem. Seams like I can't stream the AVI from embedded resources, so I guess I need to save the AVI files to the users harddrive.

I need to copy all stuff to the client PC in case of network problems.

how to I prevent common users going to their harddrives and watch admin AVI files?

Restrict The Input On An InputBox?

Oct 6, 2009

I am wanting to restrict the input on an InputBox and I am confused about how to do that. I know what to do on a text box to restrict input to numbers, the ".", and the backspace key, but I cannot figure out how to tie the input restrictions to the pop up InputBox. Do InputBox 's have an object name attached to them? Or are they just called InputBox.whatever?

C# - Restrict Same User To Login From Different Machines

Jun 8, 2012

I 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 .

Restrict Access To A Tab In A Form Application?

Apr 25, 2011

I am building a simple windows form application in Visual Basic 2010 with two tabs. It's a program that will allow a business to enter contact information for display to an end user client.

One tab displays the business contact information for the end user client, which I have the data filled from a App.config file.The other tab acts as a settings page. The business fills in their contact data on the settings tab for the App.config file.

Once the business contact information is entered into through the settings tab, I want to be able to restrict the end user client access to the settings tab.It doesn't need to be highly secure, just a way to prevent the average end user from getting into the settings tab.
