SectionSetSize when updating

[superruzafa]

Hi.

I'm patching several files which are already installed in HD.

I need to File them to extract in $TEMP folder and then use them as patch. NSIS uses these file sizes to estimate the size of the section contains them.

Since I'm not making an installer but a updater, I'd need the section size shows 0 Kb when a user select it (I have several categories for updating)

I've tried two ways to get this:
[list=1][*] Dinamically, in .onInit, I have set all sections to 0 Kb, with SectionSetSize. Doesn't work.[*] Add in whole sections a AddSize instruction with the negative file size of that section. (this is a bit wicked) Doesn't work [/list=1]

Maybe I'd need to use a merge of both solutions, but I want to ask if anybody happens this.

A newbie bug

A used SectionSetSize SEC_INDEX instead of SectionSetSize ${SEC_INDEX}

Thanks anyway.
