I am trying to put version information to my C# GUI framework retrieved from the latest ClearCase label. This was originally done from Visual Soursafe as below.
I really wish that the COM interfaces had better documentation, or were more obvious. Or that the code to ClearCase Explorer or Project Explorer were open source.
I've done a few cool things, but I pretty much started by adding COM references to my C# project, and then started screwing around with the interfaces I found.
Good luck!
