Background->
I would like to add something similar to my installer.  The product I am 
installing can optionally handle a lot of file extensions.  I have put 
the registry values for each extension into a feature.  I want to offer 
the user check boxes to enable support for each extension (we have found 
that if we put support for file extensions in the standard feature tree, 
some users select everything and then complain that we have stolen all 
their extensions).

The interesting* bit->
I think I have worked out how to use checkboxes to enable or disable 
features in my UI but I can't work out how to set the default values of 
the checkboxes when the user re-runs the installer and selects modify.

I add a checkbox like this->
<Control
   Id="ext1" Type="CheckBox" X="20" Y="65"
   Width="158" Height="17"
   Property='INSTALLASSOCIATIONEXT1'
   CheckBoxValue='1' Text="Support file ext 1"
/>

Then on the dialog I have a next button like this->
<Control
   Id="Next" Type="PushButton" X="236" Y="243"
   Width="56" Height="17" Default="yes" Text="Next">

      <Publish Event="AddLocal" Value="FileAssociationExt1"> 
INSTALLASSOCIATIONEXT1= 1</Publish>

      <Publish Event="Remove" Value="FileAssociationGIF">Not 
INSTALLASSOCIATIONEXT1</Publish>

</Control>

I think this is similar to how the Office 2003 installer works (the bit 
where the user decides what main apps to install) but somehow, when I 
re-run the Office installer, the "INSTWRD" property is set iff I opted 
to install Word.  How does that work?  I can't work it out from the 
verbose log.

Thanks,

Jonathan
