[python-win32] Getting the associated icon of a file type

[Richard Philips]

Hello all,

How can I retrieve the associated icon of a file type ?

I tried the following:

def getDefaultIcon(filename):
    '''Retrieve the default icon of a filename'''
    (root, extension) = os.path.splitext(filename)
    if extension:
        value_name = _winreg.QueryValue(_winreg.HKEY_CLASSES_ROOT, 
extension)
        try:
            value_name = _winreg.QueryValue(_winreg.HKEY_CLASSES_ROOT, 
extension)
        except _winreg.error:
            value_name = None
    else:
        value_name = None
    if value_name:
         try:
             icon = _winreg.QueryValue(_winreg.HKEY_CLASSES_ROOT, 
value_name + "\\DefaultIcon")
         except _winreg.error:
            icon = None            
    else:
        icon = None
    return icon
   
if __name__ == "__main__":
    print getDefaultIcon("icon.html")
    print getDefaultIcon("icon.py")


This works fine.

The result is:

1) None
2) *.ico file (e.g. D:\Python\Py.ico)
3) *.dll, *.exe
4) "%1" (e.g. .html -> "%1")

1) and 2) are ok for me.

3) and 4) pose problems.

Any help on this issue would be helpful.

Thanks,

Richard
