Ideally a DLL custom action would be added. It would be great if that were
contributed back so that everyone could benefit.
One other concern: the blank guid on your Plugin component means that this file
association, including the Open verb registration, would not be removed when
the product/plugin was uninstalled. You should create and preserve a GUID for
that component.

> Hi,
> I'm developing a plugin for XMetaL(an document editor), and set XMetaL
> the default program for a new file type, let's say, myxml. I think Wix
> Progid element can help dealing with all of this. My code is as below:
> <Component Id="Plugin" Guid=""> <ProgId Id='Authoring.myxml'
> Description='my File Type'> <Extension Id='myxml' ContentType='text/xml'>
> <Verb Id='open' Command='Open' TargetProperty='XMETALAUTHOREXE'
> Argument='"%1"' /> </Extension> </ProgId> <CreateFolder /> </Component>

> Here is my scenario: First I create a file called abc.myxml, the current
> icon of this file is blank page. Then I install my plugin, it sets XMetaL
> as the deafult program of myxml files. After the full installation, the
> icon of myxml files should change to XMetaL's icon. When I double click
> abc.myxml, it will be opened by XMetaL.
> What troubles me is that after installing the plugin, the icon of myxml
> files won't change. When I try to open abc.myxml, it raises XMetaL, which

> I found this on MSDN: "Note Any time a file association is created
> or changed, notify the system that a change has been made by calling
> SHChangeNotify, specifying the SHCNE_ASSOCCHANGED event. If this is
> not done, the Shell might not recognize any changes made until the
> system restarts."
