wine users - Jan 2005 - file associations in wine

hi there

first of all, please excuse my poor english...
I know I can associate a file extension in wine with a linux application like 
i did for .sxw in this .reg-file:

REGEDIT4

[HKEY_CLASSES_ROOT\.sxw]
@="sxw.document"
[HKEY_CLASSES_ROOT\sxw.document]
@="sxw.document"
[HKEY_CLASSES_ROOT\sxw.document\shell]
[HKEY_CLASSES_ROOT\sxw.document\shell\open]
[HKEY_CLASSES_ROOT\sxw.document\shell\open\command]
@="C:\\windows\\command\\start.exe kdestart.exe \"%1\""

where kdestart.exe is a link to the following script:

#!/bin/bash
i=`winepath -u "$*"`
kfmclient exec "$i"

so now sxw-files open in OpenOffice like I wanted. But now I would like to 
have a file association to each filetype unknown to wine, so that all these 
files will be openend with the corresponding KDE programs. I tried:

[HKEY_CLASSES_ROOT\*]
[HKEY_CLASSES_ROOT\*\shell]
[HKEY_CLASSES_ROOT\*\shell\open]
[HKEY_CLASSES_ROOT\*\shell\open\command]
@="C:\\windows\\command\\start.exe kdestart.exe \"%1\""

because i thought that would be the default file association, but it doesn't
work...

Is this possible? It would be a great step for the integration of wine with 
KDE (or GNOME, because a similar script could be developed)

thanks for any help
