V4RB2 bug 648 -> REALBASIC BUG

[Sims, John]

Hi Olivier,

Yes, that looks better.

Out of curiosity, I tried a similar experiment with VB.NET (I'm at work and am forced to use M$ products).  Here is my code in a pushbutton:

 	  Dim i As Integer
        Dim st(999) As String
        Dim iStart As Int64
        Dim iEnd As Int64

        iStart = Now.Ticks
        For i = 0 To 999
            st(i) = "jhljhljhljhljhljhljhljhljhljhjhkjhzzzzzzz"
        Next i
        iEnd = Now.Ticks
        Console.WriteLine(iEnd - iStart)
        iStart = Now.Ticks
        For i = 1000 To 1999
            Try
                st(i) = "jhljhljhljhljhljhljhljhljhljhjhkjhzzzzzzz"
            Catch err As Exception
            End Try
        Next i
        iEnd = Now.Ticks
        Console.WriteLine(iEnd - iStart)

Results:
First run
No handler: 0 ticks
Handler: 63090720 ticks

Second run (crappy .NET never does well on the first run of anything :-/)
No handler: 0 ticks
Handler: 33648384 ticks

In .NET, a tick is defined as "The value of this property is the number of 100-nanosecond intervals that have elapsed since 12:00 A.M., January 1, 0001"
