I'm creating a feature for my software that bans the user for 10 minutes if he/she has failed to login thrice.
The problem is, I don't know how to code that. I got ideas on how to do it but I don't know what predefined classes or functions to use.
what classes or functions to use to code this feature?

View 5 RepliesI would like to try and implement a feature wherby once you have logged into an application (straightforward winforms application) and had your credetials verified the application would then force you to log on again if no activity had been detected in the application for a certain number of minutes. In essence I want to provide some extra security for those occasions when users get up and wander away from their machines for prolonged periods.
I have all the logic for logging into the application, it's just the checking for no activity over a given period and then forcing the user to log back in again that I'm not having much luck with.
I am looking for formula that is accurate in converting Minutes to Decimal Minutes i.e 30 minutes is 50 Minutes in Decimals so 1.3 hours is 1.50 and not 1.5 i have used Minutes/60 but it is not accurate as some times i have to Multiply the result by 100 and some time 1000 to get correct results based on single digit Try 1/60, 10/60 99/60 or 100/60.What would be the most efficient and correct way to Convert the time into Minutes ?

I am writting a timer with info and code gathered here. If you just set the Minute list box to 1 you will see what I mean. Also, you need to select each Listbox which turns them blue. I would like to do that with code too. Here is the code that is problematic.
'Timer1 from toolbox needed
'I have 4 textboxes Hours, Minutes,Seconds,Milliseconds.
'When textboxes values are set the count down begins.
'You need 4 labels, label1 is alone, the other 3 are above textbox and listbox the hours minutes second
'You need 4 textboxes. The 4 textbox is hidden or out of the way.
'You need 3 Listboxes.
'Lay out the label1 at top of form. Below that are hr, min, sec. labels.Below that the three textboxes and below that
'are three listboxes.
'Textboxes only show the original time

Is it possible to configure the System.Timer to run say 30 minutes after every hour? I have searched google to figure this out but all it shows is how to set it where it goes off once an hour, if I launched the app at 2:45 then it would go off again at 3:45. I can forsee issues down the line with this approach where if it went off at a specified time it would not have that issue.
Normally i would use Scheduled Task for this however it doesn't give you the option for hourly just daily, perhaps i'm wrong about this.
I need a timespan difference result in - hours:mintues format.
