Hi Folks,
I'm trying to build a better mousetrap in a client-server environment
that displays information in a set of listboxes.
I have three listboxes:
lbJobDefinitions
lbSystems
lbFiles
The first contains a list of job definitions that each contain a list
of systems and selected paths on the systems
• The row listindexes in the first lb match the array positioning
for the definitions.
• The definitions contain a list of systems and paths that will be
represented like this:
"/My Solaris Server/usr/local/somedir"
• The path is separated by the slash character and the first entry
is the system name that will match the systems in the second lb.
The second contains the list of authorized systems (should match the
contents of the various jobs in lbJobDefinitions)
The third is a filesystem hierarchical display for the selected system.
My goal is to synchronize the contents of the three listboxes using a
combination of arrays (based on the first lb) and dictionaries that
compare the third lb to the file selections contents (another array)
based on the currently selected item in the second lb. Therefore, if
I select a job that has 3 systems with multiple paths selected, as I
select each system in the second lb and expand its filesystem
components in the third listbox, I want to update the hi-light for
the entries in lb three to indicate a match to the filesystems in the
job selected in the first lb.
If you're still with me, currently as I expand each element of the
filesystem in lb three, I store the full shellpath for the displayed
item in a hidden column in that new row. This string value is what I
compare against the members of the array for the selected system.
This is where I believe that a dictionary will really speed things up
since each system could have hundreds of filesystem selections.
Currently, I'm comparing each row of the lb three as a new folder is
expanded, but a for next comparison loop through ALL of the
selections gets progressively worse the more comparisons that most be
performed. If I use a dictionary, the use of a construct such as:
If d.HasKey(lbFiles.Cell(theRow, PathCol) Then
// hi-light as a match in lb three
End If
My current sticking point is how to maintain the dictionaries across
multiple methods that are global in scope and not part of the
listboxes' parent window's code scope.
I'm very open to thoughts and design guidance since I'm now going
bald from my own hair pulling ...
Thanks for any thoughts,
Tim
