    I just recently jumped from VB6 to VB.Net and I was wondering if VB still had the problem of hogging memory and not properly unloading all the forms?

    I tried googling for code to include in my applications but I did not come up with anything.

    I would greatly appreciate it if someone has the solution to this

    Just Dispose of objects when you're done with them, don't declare more than you need, don't reference a library if you don't have to.  It's that simple Wink [;)].  Oh, and Task Manager doesn't really give you a very good picture of how much memory your application is actually using (or so I've heard).

    Try to create some very large string and dispose it, do it in cycles and app will fall with not enough memory ... It wouldn't catch up with clearing memory... e.g.

    sub main()
     call cs()
    end sub

    sub sc()
    dim x as string=space(100 000 000)
    end sub

    Big Smile [:D] ... only joke, but it will really fall after few cycles

    Haha, well my system wouldn't even do that once, no error, it just didn't do it.  I was thinking more along the lines of:
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
          Dim i As Integer

          For i = 0 To 100
             Dim bmp As New Bitmap(10000, 10000)

             Me.Text = i.ToString

       End Sub

    This code actually runs, albeit slowly since it's allocating 10,000 x 10,000 x 3 (Width x Height x Bytes per Pixel) = 300,000,000 bytes of memory (about 286 megabytes).

    Long story short, you shouldn't have to worry about .NET and it's garbage collector.
