UnisntallData.RemoveItem() question

[jassing]

I have this code in a "post install" screen

UninstallData.RemoveItem(UNINDATA_SESSIONVARS, "%RawReg2%");

As we don't want to expose the value of "RawReg2" to the user.

However, this variable still shows up in the uninstall.xml file.

How do we go about removing it using this call? I have a LOT of invested time into using this call -- so I'd rather not have to resort to using the xml plugin to remove these entries....

Thanks

Josh,

I am not totally clear on what the question is. At first glance I would say that you need to expand the session variable but that may not be what you are asking. Please explain further

Thanks Adam.

When I run thru my installer, the uninstall.xml file contains a session variable "%rawreg2%".

I want this variable removed from the uninstall.xml file -- the reverse of
UninstallData.AddItem()

I didn't ADD it to additem, but assume it's there becuase of the sessionvariable declaration.

So; the question is --

1) How can I remove the specific session variable from uninstall.xml?
B) does UninstallData.RemoveItem() work?

I couldn't get this working either. I have logged for a dev to look into. REF:14937

Rats.

I don't suppose you have some xml.stuff() code that could remove items based on <name></name>?

An xml file is just a text file. You could use something like TextFile.ReadToString and String.Replace on the item in question. No idea what this would do to your uninstall.

This is the code I came up with.

function uRemoveSessionVar( cName )
  local nElements = XML.Count( "SUF70UninstallData/SessionVars", "Var") ;
  for x = 1,nElements do
    if XML.GetValue("SUF70UninstallData/SessionVars/Var:"..x.."/Name") == cName then
      XML.RemoveElement("SUF70UninstallData/SessionVars/Var:"..x);
      x=nElements;  -- force end of loop
    end
  end
end

Since I'm removing a lot of variables that just aren't needed in the uninstall;
I do this in my "post install" routine:

if File.DoesExist( UninstallData.GetConfigurationFile() ) then
    Application.SetLastError(0);
    XML.Load( UninstallData.GetConfigurationFile() );
    if Application.GetLastError() ~= 0 then
      -- Error loading XML
    else
      -- Pull elements out.
      uRemoveSessionVar( "%RawReg2%" );

      XML.Save( UninstallData.GetConfigurationFile() ) ;
    end
  else
    -- File isn't there.
  end

Of course, i could make this a lot more useful by including the various values
UNINDATA_SHORTCUTS, UNINDATA_SESSINVAR etc and adjusting the code; but all I care about (for now) is the session var....
