thanx , you both cleaned my perspective with those abstract concepts ! Jarno Burger Video Jockey

hey, i must say i am letting all my friends run crazy over this world that i am in at this present moment. Troy :laugh:

Last July my boss asked me to work from home most days. I used VPN either from my home desktop or from a laptop to remote into the system in my office and access VS with no trouble. I wouldn't try to open the same solution on two systems at once.

Hi, trying to learn the GOF patterns Good thing to learn about, I finally bought the book a few months ago. trying to serialize my tree , filled with nodes I had a look into serializing a tree and I got as far as serializing the objects contained within the nodes and leaves but not the actual 'tree' information such as child/parent/leaf used to construct the tree. Which meant I could not reconstruct it. When running my (C++) program I used a Windows tree control CTreeViewCtrl to visualize the data and a third party tree container to actually hold and manipulate the data and linked the two together. I serialized the various classes that made up the objects held in the tree container using the Boost library but was not serializing the container structure. The question then arose as to should I serialize the container - which would then make the program dependant upon that container. If I did, how? This is where I left it a few months ago. my leaf objects cannot have children. Leaves cannot have children, thats correct -xml serializer cannot recognize what kind of object a child is. I used the Boost library which got round this by allowing simple additions to class code to allow each object, when serialized, to store what type of object it was - and what it inherited from. Reconstructing then created the correct objects.

If you want the command to be an enum, you have to have all the values in the same enum. However, you can create static classes with properties to create an hierarchy for the values: Enum AllCommands General_Nada Error_IO_FileNotFound Error_IO_PathNotFound Error_Access_Denied End Enum Public Shared Class Command Public Shared Class General Public ReadOnly Property Nada As AllCommands Get Return AllCommands.General_Nada End Get End Property End Class Public Shared Class Error Public Shared Class IO Public ReadOnly Property FileNotFound As AllCommands Get Return AllCommands.Error_IO_FileNotFound End Get End Property Public ReadOnly Property PathNotFound As AllCommands Get Return AllCommands.Error_IO_PathNotFound End Get End Property End Class Public Shared Class Access Public ReadOnly Property Denied As AllCommands Get Return AllCommands.Error_Access_Denied End Get End Property End Class End Class End Class Now you can get the FileNotFound command either by using AllCommands.Error_IO_FileNotFound or Command.Error.IO.FileNotFound. Despite everything, the person most likely to be fooling you next is yourself.
