disable back button
Hello.
Sorry to dump this in the forum but I couldn't find anything in the docs, in the forum,or in the archives.
I guess this is an very old question .... :(

I need to disable the back button once I reach the components page.

I know how to disable the backbutton on a custom page. but I don't know how to do that on a normal page.
Any ideas ?

Thanks,
Crisp

Maybe you could get it to call Abort from the page's Pre function (not the current page, but the page before it)
This way when the user clicks back, he won't go anywhere.

Page Components CompPre
Page Directory DirPre
Function CompPre
 StrCmp $R0 Abort 0 +2
 Abort
FunctionEnd
Function DirPre
 StrCpy $R0 Abort
FunctionEnd

Is there a solution to this?

I'm needing to disallow going back from the components page.

Get the handle of the Back button using GetDlgItem (the ID of the back button is 3) and use EnableWindow to disable it.

an example of this would be extremely helpful, using the getdlgitem and sendmessage functions in nsis have been extremely confusing for me.

thanks for your time,

Var BACKBUTTON

GetDlgItem $BACKBUTTON $HWNDPARENT 3
EnableWindow $BACKBUTTON 0
