Operation limited by time (vb.net)

[IWeb]

Hello,

 

I want to process an operation (e.g. a while loop) for a certain time (in seconds).

Is there a function/way in vb.net to count the passed time?

I tried to use timevalue.seconds but this return only the seconds from 1 to 60 from the local watch.

 

thank you,

ok. i developed a working but not good solution:

 

       Dim tSpan As TimeSpan
       Dim tDate As Date
       Dim interval as integer=10

       tDate = Now

 
       While tSpan.Seconds < interval
           tSpan = DateTime.op_Subtraction(DateTime.Now, tDate)
       End While

Dim i As Int64 = DateTime.Now.Ticks
Dim interval As Int32 = 10000 'Milliseconds

While ((DateTime.Now.Ticks - i) <= interval)
   'Loop
End While
