I've got a DGV and a timer, I want to hide the DGV after 15 minutes of inactivity on my form. How can i do this? I've got a number of other controls (textboxes, buttons etc).
I thought somehow I could reset my timer every time a mouse moved on my form but would this create to much running on the mouse code when a user moved the mouse on my form?
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 ?

View 2 RepliesI'd like to find a tutorial that shows how to logout after a certain period of inactivity.By logging out, i mean writing a Row to my SQL database. The database table was designed with a column called user_status. When a user logs in, ASP writes a row called "logged in" into the database table. I want to find an automatic mechanism that writes a Row to the database after a certain pd of inactivity

I am developing a parental control application containing a feature that logs a user off of the computer after an administratively set period of time. I do not however want the application to continue counting time against the time limit when the user is not active on the computer. EXAMPLE: Child logs on and is active for an hour then leaves computer for 45 minutes to get dinner. The session timer needs to ignore the 45 minutes of inactivity. I have thought of two ways to accomplish this.
1) Use a SystemEvents.SessionSwith event (to detect the Start Menu > Log Off > SwitchUser action), or
2) Use an event which would detect user inactivity in excess of a set time, e.g. 5 minutes (similar to a screensaver).
Either event would call a method which would simulate a pause feature (as StopWatch and Timer have no pause support that I know of). I believe the 2nd option would prove to be more universally affective as 1) some users do not have Fast User Switching enabled, and 2) users would be required to manually switch users in order to prevent their inactive time from counting against them. My problem arises when I attempt to implement one of these methods. According to the IntelliSense error checking engine, I have absolutely no clue how to do either of these tasks in spite of the research I have conducted on the topic. I would prefer to go with the system idle time approach.
I have an application that provides a countdown for 60 minutes and I'm currently using the win form timer and it updates some labels and a progressbar. Now I have to change this to be a countdown for 360 minutes. Will the win form timer be sufficient or should I implement a Timers.Timer instead?
View 6 RepliesI'm curious if it is possible to hide a group of text boxes from view in a form until a particular condition is met, and to have a custom set of text boxes for that condition. To give an example; I want radio buttons offering choices for a manner of searching records, the user selects one and then a specific set of text boxes are displayed for the user to utilize, if a different option is chosen a different set of text boxes will be shown. Is this something that can be done?

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.
