Saving User Data on back

Hi,
I am wondering if anyone knows how I could set the values of text fields when the user presses the back button..
something like this:

Function OnChange

    Pop $0 ; HWND

    System::Call user32::GetWindowText(i$Text_ccip,t.r0,i${NSIS_MAX_STRLEN})

    Strcpy $CCIP $0

FunctionEnd



; on the bottom of my verification page i have the 

; following code just before the end of the custom page 

; function



; GetFunctionAddress $clnow clearnow

;    nsDialogs::OnBack /NOUNLOAD $clnow

;   nsDialogs::Show /NOUNLOAD

;FunctionEnd



Function clearnow

    nsDialogs::SetUserData /NOUNLOAD $Text_ccip $CCIP

    ${NSD_SetText} $Text_ccip $CCIP

    Strcpy $Text_ccip $CCIP    

  

FunctionEnd

I am saving value entererd in the above text box into $CCIP.
when the user presses the back button the text fields (here text_ccip gets cleared. I want the user entered data to remain in the text box on pressing the back button. how could I use either the above or NSD_getstate? Any suggestions?

this is taken from the Memory section of the nsDialogs section of the manual and modified with your vars (I think)
anyways it compiles fine and does save the text in the text box when they click back

!include nsDialogs.nsh

!include LogicLib.nsh



Name "nsDialogs Example"

OutFile "nsDialogs Example.exe"





Var Text_ccip

Var Text_ccip_State



Page custom nsDialogsPage nsDialogsPageLeave

Page directory ;--need a page to go back from 





Function nsDialogsPage



	nsDialogs::Create /NOUNLOAD 1018

	Pop $0



	${NSD_CreateText} 10u 60u -20u 13u $Text_ccip_State

	Pop $Text_ccip





 nsDialogs::Show

   

FunctionEnd





Function nsDialogsPageLeave



	${NSD_GetText} $Text_ccip $Text_ccip_State

	



FunctionEnd

Hi, thx for your reply..
I tried the above code but it did not work..
Have attached the script i wrote...
it's a messy script so i apologize for the aesthetics/logic.

Suggestions are welcome.

Thanks

Solved

Solved:

I was calling nsdialogs:: onback unecessarily in the script. @ZmAn3: your code works.
Thanks.
