2 Reg Keys, 1 Install Dir

hi!

i want to search for reg key A und reg key B. when the one of these keys is found it should be the install dir.

i tried it with

InstallDirRegKey ...
InstallDirRegKey ...

but it don't work

...

Do something like this:

function .onInit

ReadRegStr $0 [RegAddress_A]

StrCmp $0 "" 0 Found

ReadRegStr $0 [RegAddress_B]

StrCmp $0 "" NotFound

Found:

StrCpy $INSTDIR $0

...

NotFound:

...

functionend

What error does it give you?

I'ld have written ...

function .onInit
ReadRegStr $0 [RegAddress_A]
ReadRegStr $1 [RegAddress_B]

; if $0 and $1 are null -> goto notfound else continue

StrCmp $0 $1 NotFound 0

; (we dunno which one is the right one)
; so if $0 is empty, copy $1 (which is not) into $0

StrCmp $0 "" 0 Continue
StrCpy $0 $1

; now $0 has got the right path

...

NotFound:
...

functionend

.. sorry, i forgot a label 😁 !


StrCmp $0 "" 0 Continue
StrCpy $0 $1
Continue:

😉

veekee, my code works fine.
weidhas, an example? The code supplied already was an example. But ok.

outfile 2regs.exe

name 2regs



function .onInit

  ; Make sure we have a regentry

  WriteRegStr HKLM "Software\2regs" "dir" "c:\My docs"



  ; Now check the regentries as if

  ; we don't know the info above

  ReadRegStr $0 HKLM "Software\skjgllfsg" "dir"

  StrCmp $0 "" 0 Found

  ReadRegStr $0 HKLM "Software\2regs" "dir"

  StrCmp $0 "" NotFound

  Found:

  StrCpy $INSTDIR $0 ; So $INSTDIR contains install dir

  MessageBox MB_OK $INSTDIR

  Goto Continue

  NotFound:

  MessageBox MB_OK "No regsettings found!"

  Continue:

functionend



section

  DeleteRegKey HKLM "Software\2regs"

sectionend
