File version check for file
'H:\WINDOWS\System32\Macromed\Flash\Flash32_11_2_202_235.ocx' returned false for
operation type versiongreaterorequal.
Checking file version 11.2.202.235 is versiongreaterorequal (than) 11_2_202_235
- got result -1.
It was never claimed to work like this. Version 11.2.202.235 is clearly a
different string than 11_2_202_235 and therefore it's not equal.
I've even tried to point this out in my first reply. Since for WPKG there are
not version delimiters (".") in the underscored version string it is regarded as
being "one version component". As a result WPKG compares the first components
which means it's comparing 11 against "11_2_202_235". Internally WPKG assures
that both string get equal number of components:
11-0-000-000
11-2-202-235
Which makes WPKG finally believe that 11.2.202.235 is a lower version than
11_2_202_235.
And before you ask. I thought about accepting underscores as component
delimiters seamlessly as dots. But finally I came to the conclusion that it's a
bad idea as some underscores might be used by some software in the same way as
dashes are used sometimes:
- 1.0
- 1.0-1 (or 1.0_1)
- 1.1-0 (or 1.1_0)
- 1.1-1 (or 1.1_1)
- 1.1-2 (or 1.1_2)
I believe that the current algorithm is very stable and flexible. But comparing
two completely differently formatted version string is almost impossible to do
with full automatic detection. So for flash you might either define two
variables with dotted and underscored versions or just use either of them. But
do not mix.
If you're checking for file version of a file which has the version already in
the file name itself, then a simple file exist check should be sufficient as
it's extremely unlikely that a file named Flash32_11_2_202_235.ocx contains a
version other than 11.2.202.235.
