vb 2005 and simple way to wright listview and all its propities to file

[John]

Hi not sure were to post this but would appreciate if someone knows
simple answer...... which usually never exists

hi have added all my items subitmes and colors etc to my listview1 in
vb 2005
is there a simple way to save the whole object to file
instead of iterating though each property
such as
Private Sub Form1_FormClosing(ByVal sender As Object, ByVal e As
System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing
FileSystem.FileOpen(1, "j:\test\lvobj.txt", OpenMode.Output,
OpenAccess.Write, OpenShare.Shared)

Write(1, obj.ToString)

FileClose(1)

End Sub
then read it in at program start

dim the file as a listview1
and it would have all my items and subitems and colors, you know
something simple

PS isn't there something magical like saveobj(.....................)
I know i'm dreaming

thanks in advance

I'm not sure if the listview is serializable or not, but if it is you
can just serialize it to xml or a few different formats. You should be
able to find some serialization examples on google or in the ng
archives, just try to adapt those to the listview. If the listview
cannot be serialized, than you might be able to just save the
datasource to a file and restore the listview from there. Datasets and
datatables expose a SaveXml() and LoadXml() method that you can use
for this.

Thanks,

Hi,
I'm not familiar with listview at the moment, but here is a code that
saves all the items of a "listbox" into a text file:

Dim myArray(Me.ListBox1.Items.Count - 1) As Object
Me.ListBox1.Items.CopyTo(myArray, 0)
Dim Data As String = Join(myArray, Environment.NewLine)
My.Computer.FileSystem.WriteAllText("c:\test.txt", Data, False)

Sorry, it's not listview control, but it might give you idea to
manipulate the same thing for listview control.
