Android Question Timers

[Paul Boyle]

Hi

I have an app with multiple games, each with a button the main activity/page. One requires a timer, so that when this games button (eg. btn_MyGame) is pressed it starts that game's activity and the timer is started.

I'm wondering how to start the timer when btn_MyGame is pressed and show the time elapsed on a label within the MyGame activity.

So after 3 mins of playing MyGame the label would read: Session Time 0h 3m

I know very little about timers (obviously).

Any help appreciated.

Many Thanks.

P.

You start a timer by calling Timer.Enabled = True.
You can store the current time in a global variable and then compare DateTime.Now to the stored time in the Tick event. Search the forum. There are examples of clocks / timers.

What data type is the variable for storing the current time.

Dim Timer01 as Timer
-------------------------------

If FirstTime = True Then
Timer01.Initialize("Timer01",1000)
End If

---------------------------------

If Timer01.Enabled = False Then
Timer01.Enabled = True
End If
----------------------------------

Dim StartTime as ???????

Dim GameTime as ??????

GameTime = DateTime.Now - StartTime

Anyone got any handy code for displaying Hrs, mins & secs in a label.


This errors out.

DateTime.TimeFormat = "HH:mm:ss"

lng_GameTime = DateTime.Now - lng_StartTime01
lng_GameTime =DateTime.Time(lng_GameTime)

lbl_Timer.Text = lng_GameTime


Or is it better to use the Mod math function?

What was the error message ?? majority of times it will point directly to the problem .

try this ..

Dim lngStartTime, lngEndTime, lngGameTime As Long  
lngStartTime = DateTime.Now
'.............
'...... game over
lngEndTime = DateTime.Now + 62000 '...  @@@ for example only ! .. add 1m:02sec)
lngGameTime = lngEndTime - lngStartTime

DateTime.TimeFormat = "HH:mm:ss"  
Log (DateTime.Time(lngGameTime))

Thanks a lot. I have the below code which works but for one thing.

Sub Timer01_Tick
   
    lng_GameTime = DateTime.Now - lng_StartTime01
   
    DateTime.TimeFormat = "HH:mm:ss"
   
    lbl_Timer.Text=  DateTime.Time(lng_GameTime)
   

End Sub

lbl_Timer.Text starts up as 01:00:00 instead of 00:00:00, which is probably down to summer/winter time zone. Is there a way to determine if its +/- 1hr ?

Thanks.
