Question about component page

Hi Guys,

i wonder if you could help me out here, i have been creating a new script for NSIS and i am having a problem in a couple of areas, if you could help me out i would appreciate it, have already searched through the forums and google before asking to make sure it hadnt been covered.

Basically i want my UNINSTALLER component page to have the checkboxes either enabled or disabled depending on a registry value (i.e. is that software installed and if it is make the box have a tick in it and if its not remove the tick) - im currently using a single section group and 3 products within that group

here is the relevant code:

Function un.onInit
;READ REGISTRY STRINGS AND SET THE CHECKBOXES ACCORDING TO WHAT IS INSTALLED

ClearErrors
EnumRegKey $0 HKLM "Software\MySoftware\MyApp\Sections" "Product1"
IfErrors 0 keyexist1
!insertmacro UnselectSection ${unSec01}
SectionSetText ${unSec01} ""
keyexist1:
!insertmacro SelectSection ${unSec01}
SectionSetText ${unSec01} ""

the above doesnt seem to work as sometimes the checkboxes on the components page disappear completely!

anyone got any ideas?

thanks,

Dazza

err, yeah, lets try moving this thread to the NSIS discussion area and out of the breaking news forum, you might get a response!


/ohhh, look, I don't think I've ever posted in here before, hai guyz!

Setting no text on a section hides it from the components page. You need to use the SetSectionFlag macro in Sections.nsh and set ${SF_RO}.

yes that works however i didnt explain myself properly above, i want to add/remove the tick in the checkbox and not disable it

thanks for such a quick response too

There are macros to select and unselect sections in Sections.nsh.
