I use the following handler for QuickTime version checking in my stacks:
on checkForQuickTime
constant cQTversionNeeded = "4.1"
put qtVersion() into theQTvers
set itemdelimiter to "."
if item 1 to 2 of theQTvers < cQTversionNeeded then
answer warning "This program needs QuickTime " & cQTversionNeeded & \
" or later show video clips." & return & return & \
"Quit this program or Continue for now without video clips?" \
with "Quit" or "Continue (no videos)" titled "Unable to Show
Video Clips"
if it is "Quit" then
quit
end if
end if
end checkForQuickTime
I tend to check major.minor version numbers only since the third
version level (the "2" in "5.0.2") is rarely necessary.
Cheers
Peter
