Bug or error in script ( IntCmp)

BioDuo · 30th August 2005, 12:46

Well for some reason, yet unknown to me.
The following script will jump each time to "install"
is it a bug in IntCmp that it can't reconise a '.' in it
or is it something else?

Function .onInit

StrCpy $0 "1.64"

IntCmp $0 1.65 install old 0
IntCmp $0 1.71 install 0 new

old:
MessageBox MB_YESNO|MB_ICONEXCLAMATION|MB_TOPMOST|MB_DEFBUTTON2 "Older version" IDYES install
Abort

new:
MessageBox MB_YESNO|MB_ICONEXCLAMATION|MB_TOPMOST|MB_DEFBUTTON2 "Newer version" IDYES +2
Abort

install:
FunctionEnd

Int signifies an integer. Since your numbers have decimals, they're not integers, and IntCmp won't work.

You should be able to use StrCmp instead.

No, those are version numbers. There are functions in the wiki that compare between version numbers, but I can't access the wiki right now to indicate them to you.
