 Valid Filenames?

Hey all. There must be an easier way to check a users input to see if it's a
valid filename than what I've been doing. I'm using VB6 Pro. is there any
way other than looking for the existance of every invalid char?

Dear Tommy,

I don't know of an API that checks, but you could just go ahead and attempt to
write the file (OPEN "test.fil" FOR OUTPUT as #1) inside an error handling
routine.  If the file opens without error, it's a valid filename.  Otherwise,
issue your warning.  Then just KILL the test file you opened.  

If the file already exists, then just open it for input first and then close
it.  If found, then all is well.
