Question about SectionGetFlags

Hi,

I have the following structure in my installer:

Section /o "Automatic Drive Partitioning" SEC_PART

	${myLogText} "**** Automatic Drive Partitioning ****"

	Call startPartitioner

	Call readPartitionerLog

SectionEnd



Section /o "Modify Windows Settings" SEC_WIN

	${myLogText} "**** Windows Settings Configuration ****"

	Call instWin

SectionEnd

In a separate file called Dialogs.nsi, I have defined some functions that display custom pages. These pages are only to be displayed if a certain section is selected. In order to do this, I use something like this:

Function preWin

	SectionGetFlags 1 $R0 

	IntOp $R0 $R0 & ${SF_SELECTED} 

	IntCmp $R0 ${SF_SELECTED} show 

 

	Abort 

 

	show: 

...

FunctionEnd

Thus, if section SEC_WIN is selected, I would see the function that starts with the above code.

My "problem" is that if I have to add a new section and I want it to appear before an existing one, I would have to modify my Dialogs.nsi every time to update the section index.

In order to avoid this, I tried using the section ID instead of the index, as such:

Function preWin

	SectionGetFlags ${SEC_WIN} $R0 

	IntOp $R0 $R0 & ${SF_SELECTED} 

	IntCmp $R0 ${SF_SELECTED} show 

 

	Abort 

 

	show: 

...

FunctionEnd

Problem is, when I do this, I get a compile error stating that:
warning: unknown variable/constant "{SEC_VID}" detected, ignoring (Dialogs.nsi:50)
Usage: SectionGetFlags section_index $(user_var: output flags)

I suppose this is because the Dialogs.nsi file is included before my sections are defined and as such, the variables ${SEC_WIN}, etc. don't exist yet. Is there any way to avoid using the section index numbers and use the identifiers instead?

Thanks,
Mircea

Include the file after your sections.

Ok, I needed to change some things around there (had also some variables declared) but this works. Thanks for the simple solution!

If you don't want to move things around in the include file you could put the code that uses the section ids in a macro, this allows you to include the file early and insert the macro after the sections...
