CLASS: CShellUrl
|
|
|
|
DESCRIPTION:
|
|
This object was created to keep track of a FULL SHELL URL.
|
|
This includes any object in the shell name space and how
|
|
to interact with that object. Objects can be specified as
|
|
PIDLs and then will be handled appropriately when executed,
|
|
which means it will Navigate to the object if the object
|
|
supports navigation or "browse in place" (registered DocHost,
|
|
Shell Folder, Internet URL)
|
|
otherwise the Shell Url will be executed (files, shell items).
|
|
|
|
If a string is inputed by the user, the ::ParseFromOutsideSource()
|
|
method should be called. This will take all of the environment
|
|
information into consideration (CurrWorkDir & Path) and parse
|
|
the URL. If the string needs to be shell executed, it will
|
|
generate the command line arguments and current working directory
|
|
string. If the object is to be navigated to, it will determine
|
|
the navigation flags (for AutoSearch and similar things).
|
|
|
|
PERF:
|
|
This object was build so that if you specify a PIDL or String,
|
|
it should be able to hold that information without a perf hit.
|
|
If you want to take advantage of ::ParseFromOutsideSource() or
|
|
::Execute(), it will require a little more CPU time to do the
|
|
full functionality.
|
|
|
|
GOAL:
|
|
The goal of the parsing is to make it into a normal internet
|
|
URL unless the algorithm can with certainty assume that the string
|
|
entered is specifying a Shell Name Space item or action. This means
|
|
that CShellUrl will only assume the entered text is a Shell Item to be
|
|
Navigated to if it can successfully bind to the destination pidl.
|
|
It will assume it's an item to be executed and use the end of the
|
|
string as Command Line Arguments if: 1) It can bind to the end PIDL,
|
|
and 2) The end pidl is not "Browsable" or "Navigatible", and 3)
|
|
the char after the string specifying the PIDL is a Space.
