View 4 RepliesI just made a multidimensional array that was 1024 x 1024 x 1024. I get an OutOfMemory exception. What is the largest size multidimensional array that is safe to use? I'm doing this in VB.net so all .net answers are acceptable.
EDIT
When I said safe, I mean, a good size for just about any computer. What size would run smoothly on a 32bit operating system. I didn't realize that the 1024 size was 4G. I'm hoping for something a 16th of that.

I'untangle a particularly malodorous collection of spaghetti code. Anyway, I have the following XAML code:
<UserControl.Resources>
<CollectionViewSource x:Key="XMLObjectGroups" Source="{Binding Path=XMLObjectList}">
<CollectionViewSource.GroupDescriptions>
<PropertyGroupDescription PropertyName="IsDateType"/>
[code].....
On the second line XMLObjectList is a readonly property of a ViewModel class, returning a Collections.ObjectModel.ReadOnlyObservableCollection(Of MyOrder).On the final line SelectedOrder is a property of the same ViewModel class, which allows setting and getting of a MyOrder object.
I have confirmed that XMLObjectList is being correctly referenced by renaming the property, mistyping the string, breakpoints, etc. XMLObjectList definitely references the XMLObjectList property of this particular ViewModel class.The SelectedOrder property, however, is never accessed at runtime, meaning that it isn't properly hooked up to the SelectedItem of this ListView.
