It took me a while to get some time to look into this again, but you do have an excellent point. You cannot reassign the object itself unless it is passed ByRef. Here's the Q&D test I did:

Private Sub test()
	Dim a As New ItsAClass("The Original text")

	MsgBox(a.text)

	modifyClassByVal(a)
	MsgBox(a.text)

	modifyClassByRef(a)
	MsgBox(a.text)

End Sub

Private Sub modifyClassByVal(ByVal c As ItsAClass)
	c.text = "The text can be changed"
	c = New ItsAClass("Can't change this object")
End Sub

Private Sub modifyClassByRef(ByRef c As ItsAClass)
	c.text = "The text will be lost when the new object is set."
	c = New ItsAClass("A new object")
End Sub

Public Class ItsAClass
	Public text As String

	Public Sub New(ByVal t As String)
		Me.text = t
	End Sub

End Class

re: Read the Zune Collection in .NET from Zune's own API

Everytime I try and run the first three lines it deletes my ZuneStore.sdf file. Any idea why that happens? Could you post like a project file or vb file that I could download and try?

Implement a method to swap two objects

Sub Swap(ByVal Obj as Type1, ByVal Obj as Type2).

This is will be a nice example to show, ByVal and ByRef indeed have differences for class

I'm not I agree 100% with you. It's the same old story as C/C++. ByVal for a class means you can't change the class e.g consider the following.

private static void PassClassByRef(ref Class1 class1)

{

class1 = new Class1();

}

private static void PassClassByVal(Class1 class1)

{

class1 = new Class1();

}

If you write out the hashcode of a quick test for this you get...

start: 45653674

after byval: 45653674

after byref: 41149443

start: 39785641

after byref: 45523402

after byval: 45523402

Thus showing that the Byval prevents the inner function from changing the class itself rather than the state of the class as you have illustrated.

re: The Simple Sortable List for Databinding in DataGridViews

anachostic — Sat, 09 Feb 2008 03:45:12 GMT

First, make sure your listbox is set to sorted=true. That's working for me..

If you're working with a datagrid and you have the new item appearing at the bottom, try:

If dgResults.SortedColumn IsNot Nothing Then dgResults.Sort(dgResults.SortedColumn, CType(IIf(dgResults.SortOrder = SortOrder.Ascending, ListSortDirection.Ascending, ListSortDirection.Descending), ListSortDirection))

after adding the new item. Your datagrid needs to be sorted for this to work.

THANK YOU!!!

I've been searching for a couple of hours looking for this code. I found a C# version, but it uses anonymous delegates and stuff, and I'm not at that level yet.

Your code works great. I'm using it for a data bound listbox right now. The only thing not working right is that when I insert a new item into the bindingsource, it sticks it onto the end, and not into the correct sort position.

Any ideas?
