Is there any way to measure time from starting flash without using system time? System time can be changed by user when flash running
I'm also not sure what exactly you mean but if you want to grab a time which cannot be altered by user you could e.g. call a webservice and get "accurate" time.
Check this website here http://www.earthtools.org/webservices.htm.
By passing parameters for a certain region to the request you will get the appropriate time.
Other than retreiving time from a server there is no way to make sure the (system)time has not been altered by user.
There is also a function called "getTimer()" which returns the number of milliseconds that have elapsed since your app started. Refer to this url:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/utils/package.html#getTimer()
The Timer class is the interface to timers, which let you run code on a specified time sequence. Use the timer.start() method to start a timer.
Add an event listener for the timer event to set up code to be run on the timer interval.

I have a SSIS package which contain 5 sequence task container and inside that other control flow task. all are running parallel.
i am trying to have all audit and metadata information like package name,task name and current status of task (running,completed or failed.)
The Bigger Problem i feel here is how to handle once the status of the task got changed.
this information i am trying to save in sql table
package name i can get from system variable, how to get current status of Task.
i am trying to store status value like "start","in-progress","end".
May someone please share your thoughts.
Thanks
You can capture the change of a task's state by using SSIS's Event Handlers. To do this, click on the task itself and then click on the Event Handlers tab at the top of the design-time window. This will bring up a blank window with a blue link in the middle of the page as follows:
Before you click on the blue link, select a specific Event Handler that you want to handle:
From here, you can execute specific tasks. For example, you can run an SMTP mail task in the OnError Event Handler to send an e-mail alert regarding a task error. Or, you can run an Execute SQL Task in the OnPostExecute Event Handler to send data to the database once a task has completed.
I think for your specific problem (how to get Run Time for a task), you will need two Event Handlers:
OnPreExecute: Capture the system's datetime value via GETDATE() and write it to a SQL table as SequenceContainerTaskNameStartTs
OnPostExecute: Capture the system's datetime value via GETDATE() and write it to a SQL table as SequenceContainerTaskNameEndTs
Where 'Ts' stands for TimeStamp.
You can then calculate the runtime with the DATEDIFF() function and specify the time interval (e.g., seconds, minutes, hours, etc.). This value can either be stored in a separate field on the table (i.e., SequenceContainerRunTime) or simply generated on-the-fly in a SQL SELECT.

I was creating a script and i want to know how do i make the game wait until a funcion is called
If someone awnser me,ill be thankful
Firstly do not use loops, use events!
To wait for an event to happen you can use the wait method, like so:
print("Starting to wait for touch")
workspace.Part.Touched:Wait()
print("Touched!")
This will wait for the part to be touched before it continues the script.
But ofcourse, other scripts will still run, the game is not "paused", it is just that script's execution that is suspended until the event is fired.
You can also make custom "wait for call" by using for example a BoolValue like so:
local WaitObject = Instance.new("BoolValue")
function WaitOn()
WaitObject.Changed:Wait()
end
function StopWait()
WaitObject.Value = not WaitObject.Value
end
You can also place the BoolValue in the game and do the wait and stop wait in separated scripts.
If you do it in same script, remember to use different threads
I know that the Node's update method will be called every frame if we call scheduleUpdate for the current node. Is the delta parameter in the update method the same on all devices and platforms? If not, then how can I calculate what the frame rate or the delta value is on the device running my game?
I the AppDelegate you will see a line like below:
director->setDisplayStats(true);
If the value passed down is set to true you will see the frame rate of your game in the bottom left corner. You can follow that code to see how they calculate the FPS, if you want to add constant frame rate functionality to your code.
[EDIT: Based on the comment below]
The way I have done what you want in the past is by having a dedicated game controller which has a scheduled update function and I use that to set a delta value that can be passed around or accessed by other components of the game.
I am quite new to windows 8 phone and I don't know all the life cycle methods and when what is called.
My problem is the following: I have a page that loads some data from the disk and when the user exits the program ( or suspends ) the data should be saved. As far as I can tell Page doesn't have an OnSuspending method only someOnNavigatingFrom, but those are not called when you just exit the program. So I read that I should use the OnSuspending in my App.xaml.cs, but this class doesn't have this data and also shouldn't have it, maybe only for OnSuspending. But I don't know how to get the data from my page in the OnSuspending method.
The OnSuspending event is quite fragile and you cannot expect it to run and save the state for a long time. But it depends on how long it would take for you to save. It doesn't even get triggered when you hit the home key while closing the app. If you really want an easy way. Just register a background task. While your app is in the background, the state can be saved and when you open the app again things are in place.
There are certain constraints With Background task as well, you cant do heavy lifting etc...here's a link you could use.

Implement an observer pattern (i.e. pub/sub) for your view-models to subscribe to in the event that your app is being suspended.
Your app handles the suspended event. As a result, publish a message for your view-models to respond to within your app's method handler for the suspended event.
You can use an EventAggregator or MessageBus (that I wrote).
I have an html form which inserts data into a database. I just built it.. it's very basic, as I'm just doing this to learn. In doing this, I see that I can hit the back browser button and post again.. and again.. and again.. and it keeps writing to the db.
I've seen sites where I try to resubmit info and it tells me I must wait 60 seconds (or whatever). Is this the preferred method to solve this problem? If so, how does one go about implementing it?
Or maybe you would handle it a different way?
When you insert a row, store the submission time in the table, or in the user's session.
Whenever you process the form, compare that time to the current time. If it's within 60 seconds, display an error instead of inserting a row.
There are two methods :
i) Simple client side javascript:
Store the time of last event in a javascript variable,
when the user does the event again , send an alert message about timing.
( This method can be fooled though by users knowing javascript )
ii) Store the time of last event in your database at backend when the form post is done. When the same form post is done again, check for the time, if it is allowed, do the processing, else reply with a message about the timing.
