The Property Context (PC) dialog visualizes property bags in the PST. Property bags internally are
BTH structures, with the "key" being the prop id and the "value" being a six byte blob, the first two bytes of which indicate the type and the last 4 bytes indicate the value (the interpretation of which depends on the type).

At the top of the dialog is a file range control. This is NYI for this dialog.
Below that is a table view, each row corresponding to a single property on this PC.
- Property The property id followed by the property name, if known.
- Type The property type as an integer and a string.
- Value The interpretted value of this property.
