Memory Leak

[Thrain]

VB.Net code

Public Class Form1

Public aTimer As System.Timers.Timer

Public Sub Main()

Dim test As Object = CreateObject("AutoItX3.Control")

End Sub

Public Sub Start()

aTimer = New System.Timers.Timer

AddHandler aTimer.Elapsed, AddressOf OnTimer

aTimer.Interval = 2500

aTimer.Enabled = True

End Sub

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

Start()

End Sub

Public Sub OnTimer(ByVal source As Object, ByVal e As Timers.ElapsedEventArgs)

Main() 'fill WH & PK arrays

End Sub

End Class

When i executed the following code, my compiled exe constantly grows 4K each time the timer is executed. Apperently, .net garbage collection does not work on unmanaged code? If I replace this line:

Dim test As Object = CreateObject("AutoItX3.Control")

with this:

Dim test As integer = 0

the problem is solved. Thus, it is fair to say that I am constantly creating AutoItX3 type objects and the memory is not be reassigned after the sub routine finishes execution. I am not sure how I should fix this problem. Any ideas? thx!

I was able to solve the problem by doing this:

Public oAutoIt = CreateObject("AutoItX3.Control")

CODE GOES HERE...

oAutoIt = Nothing

Public oAutoIt = CreateObject("AutoItX3.Control")

oAutoIt = Nothing

May I also suggest this:

Public oAutoIt as New AutoItX3Lib.AutoItX3

Wouldnt you prefer early binding and the intellisense support!?!?!
