Unused Subs/Functions
I expect that the compiler just ignores unused subs and functions.

How do I find then in the source so I can clean up?
MZ-Tools does not seem to have anything for that or maybe I just do not
know the terminology.

Anything else out there that will do that? All I need is a list and I
can do the cleanout.

With MZ-Tools you can invoke a Source Code Review
http://www.mztools.com/v3/onlinehelp/index.html?html_review_sourc...
Although as noted this will only work with "Private" declarations.

For "Public" declarations you need to do your clean-up by hand. Simply
do a Project-wide search for each declaration. This is something that
you should be be doing periodically anyway - if you wait - it becomes
a grind.

If you have large block of functions you think are no longer used you
can simply comment out (or conditional directive) the block and then
attempt to make. Make will immediately error if it needs something.

I often use conditional compile directives while developing with
testbed functions. Something like this ...

#Const USE_TESTBED = 1

#If USE_TESTBED Then
Public Function foo() As String
....
End Function
...
#EndIF

Easy to come back later and delete the whole block. And that way I
seldom leave trash behind.

Check Aivosto Project Analyzer: http://www.aivosto.com/project/pr...

I think it does it.

Source Review (I use it) finds unused Dims and such.

I have used

#Const USE_TESTBED = 1

#If USE_TESTBED Then
Public Function foo() As String
....
End Function
...
#EndIF

but put the USE_TESTBED = 1 in the Conditional compile line.

Nice to know about using
#Const USE_TESTBED = 1

What other syntax is available?

e.g. searching Help for #if only finds if. Strange?
searching for "conditional near compile" only finds #if #else #endif

Seems someone should by now have written the XREF for VB6 (feebee).

Go to Project properties, Make tab, and at the bottom, check "Conditional
Compilation Arguments". Click the help button for more details. Here they
would apply to the whole project rather than having to use #Const in each
module. For more than one argument, use ":". Example:

USE_TESTBED = 1 : DEMO = 1

MZTools' Find callers can do this for you and works well for methods.
If you're using it on properties or genericly named members (.enabled,
..add, etc) then it struggles a bit more.

While noted in the documentation it is often over-looked that the
#Const directive is 'private' to the module in which it appears and
will over-ride any 'public' directive, whether through the project
attributes or command line. Thus a module that contains
#Const DEMO = 0
will not compile any conditional blocked with DEMO within the module
regardless of any public directive.

Because of this I often place this bit of fluff at the top of modules
that contain conditional compiles just to remind myself. <g>

' Use Public directive
'#Const DEMO = 0

But that only does it when the cursor in in the sub and not across the
entire source. Or do I not understand.

I found an XREF on planet by Ulli.
Unfortunately it has two failings for my purposes.
1) uses the clipboard badly - fails on many of my apps (but not all)
trying to write the tree when working with the icons. I coded around
it but then ... you don't get the ouput.
2) identifies discrepencies by coloring but you cannot click on the
tree node and get back the code line (has the module line and column
but that is very time consuming).

If I understood Add-Ins better I might try to mod it but alas ...

Correct, I was only expanding on the "clean up by hand" and "project
wide search".
