Uninstaller needs Reboot option

Check the reboot flag (IfRebootFlag), display a message and use Reboot to reboot.

>display a message
that is one problem - i dont know how

i just captured some syntax from "if" and vars - but the MUI? Just egypt to me :/

I found similar from the system.nsh (v1.63, your work) but i can't use it - call me a dumb.

BTW. Same problem with an additional README-MUI section - never got it.

i found a code snippet like this:

IfRebootFlag "" noreboot

  re_boot:
  MessageBox MB_ICONQUESTION|MB_YESNO|MB_DEFBUTTON2 " <bla> reboot?" IDYES +2
  REBOOT
  Abort

noreboot:


But there is something wrong - it reboots always.
must the "abort" before or after the reboot or can i use a jump on that question - dont know how

Change +2 to noreboot, e.g.


re_boot:
  MessageBox MB_ICONQUESTION|MB_YESNO|MB_DEFBUTTON2 " <bla> reboot?" IDYES noreboot
  REBOOT
  Abort
noreboot:

If you want it to reboot when the user clicks yes you should change IDYES to IDNO.

kichik

it was late today and i read again again again the manual and i changed it to IDNO and it works

not easy to a newbie

thank you

but i have a solution to my problem

; Usage:
;  push dirname\dllname
;  call exchange

Function exchange
  Exch $R1
  Push $R2
  Push $R3
  Push $R4
  ; $R1=oldname
  ; $R2=newname
  ; $R3=counter
  StrCpy $R3 0
  
  ;check first if deletable
  Delete $R1
  IfFileExists $R1 0 copy

  loop:
    StrCpy $R2 $R1.$R3.tmp
    IfFileExists $R2 0 done
    IntOp $R3 $R3 + 1
    Goto loop

  done:
  Rename $R1 $R2
  
  copy:
  ;file was found and renamed
  File "yourdll.dll"
  ;delete old TMP-files on next boot
  Delete /REBOOTOK "$INSTDIR\*.tmp"

  Pop $R3
  Pop $R2
  Pop $R1
FunctionEnd


another installer gave me that hint to rename that file, copy new file and delete old one on reboot.
i dont need the other script (UpgradeDLL.nsh]any longer :)

Now it is a fine peace of work i finshed a couple of minutes ago WITH your help

PS the function isnt perfect at all but it takes someone only a minute to make it 100% variable

PPS some explanation:
the file that has to be replaced will be renamed to <oldname.ext.counter.tmp>
counter goes up from "0" to anywhere but it is quite impossible that someone has done this a million times
before renaming it is controlled if that file is not there otherwise counter=counter+1 and loop
TMP-files are deleted on reboot

Are you sure this code works? If you can't delete the file how come you can rename it?

dont ask me that - i even wondered too but it works on my dll - unfortunately i cant delete it in any case nor the folder.

as i mentioned above this is no system-dll but it is shown in the explorer context

##
damn i posted the function into the wrong topic.

Make sure it works on every system, seems a little odd...

Is there any difference between the code in this post and the code in the other post? Looks exactly the same to me.
