Call Function only if two sections selected

[HelluvaEngineer]

What's the most efficient way to call a function only if two sections have been selected by the user, using SectionGetFlags? Sorry if this is a dumb question, I just figured there was some way to do it quickly with an IntOp & operation.

Ooops, actually meant if one OR the other is selected. What I am trying to do is check the selections from the user. They can install documentation only if one or another part of an SDK was selected. Will this work?:

PHP Code:

SectionGetFlags ${SDKDOC} $R1
IntOp $R2 $R1 & 0x80000000
IntCmp $R2 0 Skip
    SectionGetFlags ${CPPSDK} $R1
    SectionGetFlags ${COMSDK} $R2
    IntOp $R3 $R1 | $R2    
    IntCmp $R3 0x80000000 Skip
        Call InstallSDKDocStartShortcuts
Skip:

This should do it:

PHP Code:

SectionGetFlags ${SDK_PART1} $0
SectionGetFlags ${SDK_PART2} $1
IntOp $0 $1 | $0
# SECTION_SELECTED should be defined according to the NSIS version
IntOp $0 $0 & ${SECTION_SELECTED}
StrCmp $0 ${SECTION_SELECTED} 0 nonSelected
  # do whatever you want to do if one or the other is selected
  Goto done
nonSelected:
  # do whatever you want to do if non is selected
done:

Also tried

PHP Code:

SectionGetFlags ${CPPSDK} $R1
SectionGetFlags ${COMSDK} $R2
IntOp $R3 $R1 | $R2    
IntOp $R4 $R3 & 0x80000000
IntCmp $R4 0 Skip 


Still no luck. It always installs if it enters this segment.

From where are you trying to call this code? I would suggest you call it from .onSelChange, and uncheck the docs section if non of the two SDK sections are selected.

[HelluvaEngineer]

OK, the last bit of code works. Another section was calling that function.

[HelluvaEngineer]

Absolutely correct. I decided to pull this function. In the future, I will readdress it by using OnSelectChange, so that the user is aware of what's going on.

As a side note, I didn't realize that StrCmp worked for these comparisons. I was only using IntCmp. I will keep that in mind for the future.

Thanks!
