Extract compressed files by 7z.dll

[mbnoimi]

Hi all,

I want to extract a specific password protected *.7z file by using 7z.dll so I've to use CallInstDLL because I couldn't find any NSIS plugin.

I tried to use:

code:
Push "x"

Push "-t7z"

Push "files.7z"

Push "-psecret"

CallInstDLL "$INSTDIR\7z.dll" "IInArchive"

but it didn't work because of these two missing points:

1. I don't know what's the needed 7zip function to make extract process
2. I'm not sure what if I called CallInstDLL correctly or it?

Could you please help me?

I read these resources but they didn't help me here:
