Assignment operators

I know that in C++ using +=, -=, ... is faster. I was trying to see if it is faster in VB.NET or not, but I get almost same results. Maybe I'm coding it wrong(I know very very little about .NET)

can someone look at this, maybe it's kinda wrong. But I almost get the same result by using both kind of operators

VB Code:

Module Module1
 
    Sub Main()
        Console.WriteLine(OldOps())
        Console.WriteLine(newOps)
        Console.ReadLine()
    End Sub
 
 
 
    Private Function OldOps() As String
        Dim i As Long
        Dim tmp As Byte
        Dim startTime As Date
        startTime = Now()
 
        For i = 1 To 500000000
            tmp = tmp + 1
            tmp = tmp - 1
        Next
 
        Return "OldOps took " & DateDiff(DateInterval.Second, startTime, Now).ToString & " seconds"
 
    End Function
 
    Private Function newOps() As String
        Dim i As Long
        Dim tmp As Byte
        Dim startTime As Date
        startTime = Now()
 
        For i = 1 To 500000000
            tmp += 1
            tmp -= 1
        Next
 
        Return "NewOps took " & DateDiff(DateInterval.Second, startTime, Now).ToString & " seconds"
 
    End Function
End Module

I dont think you'll see any speed increase from those operators.

yeah that's what happened. I though maybe that's not a good test:rolleyes:
But I think i C++ there is a difference in speed

in my post woooo hooooo i posted on app i tried to use ++ in this app and it would not compile. Option Strict is On.

Anyone know whats up with that..? i asume that it has to be done i += 1

I dont think ++ is suported in VB with or without option strict.

I think in C++ the speed increase is because (correct me if I'm wrong!) it complies to ASM as

Code:

---

INC whatever
instead of
ADD whatever, 1

---

since VB compiles to the MSIL, I don't think you'll see a speed increase.
