ui

I've got several nested classes, with the following structure:

BackupLocation contains list of BackupClients

BackupClients contains a list of BackupVersions

BackupVersions contains a list of BackupFiles

In my UI - Im populating a combo box with BackupLocations - and have several listboxes for the clients, versions, and files.

When processing the BackupLocations - I can update my status bar easily because thats the top level class that the UI creates. But how can I update the status bar and progress bar on each file being processed? Since the BackupFiles are 3 levels deep, I cant see any way to update the UI. The actual processing of the files are within the BackupVersion class - which loads its files.

I think it probably has something to do with events and delegates - but am unsure exactly how to proceed with this, any help would be appreciated.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language.

In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
