.NET & FindControl

Hi,

I'm currently evaluating the Xtreme Suite to determine if I want to start using it in my programs.

I've hit a problem I can't work out with .NET. I'm using C# and I want to disable one of the tools in the toolbar and in a menu.

I've tried using CommandBars.FindControl([toolid]).Enabled = false;

And that just disables the first tool... using the other prototype for FindControl

Public Function FindControl( _
   Optional ByVal Type As Variant, _
   ByVal Id As Long, _
   Optional ByVal Visible As Variant, _
   Optional ByVal Recursive As Variant)

As follows:

CommandBars.FindControl(null, [toolid], null, true);

Still disables the tool, but only the first tool (i.e. it doesn't recurse). What am I doing wrong?
