Hi Palbinder, (group),

thanks for your response.

As per the link you said, an ID of "1234" is *not* acceptable ("every 
identifier must begin with either a letter or an underscore"), which is why I 
think heat does some magic to avoid that ID for a directory called "1234".

It seems that in one case heat generates the ID "Directory1234" and in another 
"_1234", and I'm wondering if this is something that one can control in heat 
(or if, perhaps, this is due to different versions of heat...)

Thanks,
Sam

Directory ID's can be anything you like as long as they're valid
identifiers (see http://msdn.microsoft.com/en-gb/library/aa369212.aspx)
since they go directly into the Directory table. They don't need to
reflect the actual name of the directory.

Just rename it after harvesting.

Subject: [WiX-users] heat: the ID of a directory with numeric name

Hi,

I am harvesting (heat dir) a directory structure like this:

foo
+ bar
   + 1234
      + a.a
      + b.b

The output is as follows:

        <DirectoryRef Id="TARGETDIR">
            <Directory Id="foo" Name="foo">
                <Directory Id="bar" Name="bar">
                    <Directory Id="_1234" Name="1234">

I am wondering about the Id "_1234". I suppose the Id cannot be purely
numeric, so the underscore is prepended.

However, I'm trying to mimic another MSI package, and that one has the
Id of "Directory1234":

        <DirectoryRef Id="TARGETDIR">
            <Directory Id="foo" Name="foo">
                <Directory Id="bar" Name="bar">
                    <Directory Id="Directory1234" Name="1234">

How can that be achieved?

Thanks,
Sam
