block flow until a condition is met
Hi all,
I hope this is not too trivial question.
I'd like to stop the installation process until a custom function return true, is there a way to poll the function repeteadly? Or is there a way to control the "Next" button in order to pass to the next page only if my condition is true?

thanks in advance

Just have a loop with a Sleep 1000 in it.

Loop:
 Call Function
 Pop $R0
 StrCmp $R0 1 +3
  Sleep 1000
  Goto Loop

Hi,
thanks for answering, this could be a way, I was wondering how to do that in a cleaner way, I mean check only when user wants to pass to the other page and stay in my page while the condition is false.

thanks again

bye

You can create a custom post function (that is called when the code is getting ready to leave the current page).

Page License "" "" LicensePost
...
Function LicensePost
    Call MyFunction
    Pop $0
    StrCmp $0 1 +2
    Abort
FunctionEnd
