Managing Sections depending on License Feature
 

Hi all,

i have a Setup that is supposed to react to features that are extracted out of a license file.

I will get back a string like "Feature1,Feature2,Feature4,Feature5" for all valid features.

I disable all(!) Sections and SectionGroups using SectionSetFlags.

Now i check for the single Features using ${Wordfind} and if a feature exists i (re)enable certain sections.

There are quite a few sections (roughly 30) and i am looking for an easier way to manage that stuff since i have to enable some sections twice (e.g. once for Feature1 and once for Feature3)

Has anyone done something like that before and would like to share knowledge?

I have attached the part of the script that i am talking about.

Thanks for your help.

could you loop over the sections, grab their text, and compare the text to a featureset variable that is based on the features enabled?

code:


Function Test

	StrCpy $0 0

	_loop:

		ClearErrors

		SectionGetText $0 $1

		${If} ${Errors}

		    goto _done

		${Else}

		    MessageBox MB_OK "[$1]"

		${EndIf}

 		IntOp $0 $0 + 1

		goto _loop

	_done:

FunctionEnd

( you might be able to abuse the section flags as well as there's quite a few bits unused )


Alternatively, perhaps you could use InstTypes with SectionIn? ( though I think that adds an installation type drop-down above the components which you would subsequently have to hide from the user )



Mind you, limiting installation features based on a 'license' like this is pretty poor protection unless used in conjunction with other functionality to prevent the user from e.g. simply extracting the files (if only file extraction would be needed).

I know, but it was (luckily) not my decision to do it that way, sadly i have to implement it :(

well, I hope the method above might be of use, then - it would provided fully automated handling of section enabled/disabled states, without having to adjust a separate section of code each time you add/remove a section to the list/etc.
