Comment, Tag
These two properties are there for
you when you need them. Both of them let you store any character
string you want and use it however you'd like.
Usage
|
oObject.Comment = cValue
cValue = oObject.Comment
oObject.Tag = cValue
cValue = oObject.Tag
|
Don't let the name Tag fool you. It has nothing to do
with indexes. It's a carryover from Visual Basic, where it means
a tag like the one you find in your shirt. It's just a place to
put identification information.We've been tempted occasionally to
use one of these properties to hold the value of another property
temporarily, so we can change it in one method and restore it in
another. (Otherwise, we have to add a custom property to the
object to hold the value.) We haven't done it because we're
concerned that someone else might do the same thing and clobber
our saved value. The right way to do this is to preserve whatever
values you might find in Tag, and append your value to the end of
the Tag. Wrap your values in delimiters that (you hope) no one
else would duplicate. This is similar to the method FoxPro uses
in its generated RI code.At design-time, both of these properties
are limited to 255 characters. However, at runtime they appear to
hold unlimited text. (We've tested them up to 100,000 characters,
far more than we'd ever be likely to store there.)
Example
|
This.Comment = "This is my whiz-bang fancy spinner sample"
oObject.Tag = oObject.Tag + CHR(13) +"*** Tamar's Add-On ***"+;
AddOn.Value + "*** EOF Tamar's Add-On ***"+CHR(13)
