how to know a shortcut target is invaild

[Billow]

hello.
I'm now very anxious to find how to know a shortcut target is invaild.
for example: test.lnk points to c:\windows\a.txt
but a.txt was deleted. so test.lnk is invaild.
how can I know it?


Thank you,
I'M LOOKING FORWARD TO YOUR REPLY!

from VB Setup-CDROM,
We can find a unsupported tools directory.
in it.
there is a shelllink class module which can verify whether the shortcut target is invaild
