programatically changing pages?

[fromcat2me]

hey, new to this thread.

I'm making an installer whose first page (custom page using IO) replaces the "back" and "next" buttons. I want the "next" button to run some code and exit (this works). I want the "back" button to continue onto the next page. Is this possible?

One solution I though of (if you can't just jump around to different pages, which is what i hope i can do) is to put a dummy page before it (so it goes back to it) which sets a global var, so the next time through the func i can just return, but if i hit "back" it keeps going back and back and back (somehow the state isnt' getting cleared?)

so basically

Page custom dummy1 ""
Page custom dummy2 ""
Page custom realFunction

if user hits "back" in realFunction
and dummy1 and 2 do nothing
shouldn't it go

dummy1
dummy2
realFunction (back)
dummy2
realFunction

?

instead i get

dummy1
dummy2
realFunction (back)
dummy2
dummy1

any help appreciated

There is a way to do this.
Have a dummy page before you're real page.

In you're dummy page put "Abort" in the main creation function.

In you're real page use this:

Function MyDialog
InstallOptions::dialog "mydialog.ini"
Pop $R0
StrCmp $R0 "success" exit ;next
StrCmp $R0 "back" back ;back
StrCmp $R0 "cancel" exit ;back

back:
### Add you're function/script here ###

exit:
FunctionEnd

I would do this, but what i want the "back" button to do is continue with the other pages in the installer. I can't seem to get rid of the fact that "back" was hit.

the structure i was thinking (similar) was

Page custom blankFunc
Page custom MyCustomFunc
Page components
Page directory
Page instfiles

where MyCustomFunc should have

InstallOptions::dialog test.ini
Pop $R1

StrCmp $R1 "back" "endLabel" "quitLabel"

quitLabel:
; do some stuff
Quit

endLabel: ; continue onto Page components
Function End


but, this doesn't continue at all, it goes back to the blankFunc page, and after blankFunc gets called it'll try and go to the page before that!

Ah ok.
I have another idea.
Do this:

code:


Page custom blankFunc "" " - A blank page!"

Page custom MyCustomFunc "" " - My title"



Function blankFunc

FunctionEnd



Function MyCustomFunc 

InstallOptions::dialog "mydialog.ini" 

Pop $R0 

StrCmp $R0 "success" success ;next 

StrCmp $R0 "back" back ;back 

StrCmp $R0 "cancel" exit ;back 



success: 

### Add you're function/script here ### 

Goto exit



back:

Abort



exit: 

FunctionEnd 

The should work...

Lacking a better idea, let the hacking begin. See attached script.
