Think of your VirtualVolume file as a file system, and root is the
highest directory you can access.
I have an application whose file format is a bunch of different
folders within the root, each of which may contain anywhere from one
to several different files. I chose to organize it that way to keep it
better organized from my perspective. The files could have all been
stored within the root (i.e. no subfolders), instead, but I chose this
way of doing it. It's totally up to you.
So the way you get something out of a VirtualVolume file is to get the
root FolderItem and then dig down from there to wherever you have
saved your data in the structure you created. Hope that makes sense.
Ahh.. ok.
Well I got a VV file made and stuffed with data.. I think.
Now getting it out seems a bit tricky. I want
to get each file (Name) listed in a listbox.
Dim vv As VirtualVolume
Dim realFile As FolderItem
Dim virtFile As FolderItem
Dim inp As BinaryStream
realFile = GetFolderItem("").Child("VirVol")
vv = realFile.OpenAsVirtualVolume
If vv = Nil then
MsgBox "Unable to open virtual volume"
else
virtFile = vv.Root.child("Data")
inp = virtFile.openAsBinaryFile()
//ListBox1.addRow inp.readPString
end if
exception
quit
