There is no good way to do this. However, you may need to rethink
your plan of having this done in the key event handler. It is possible
to have a filename string that will go though an invalid state before
becoming a valid name.
The easiest way to know that you are "valid" is to limit the name to
alpha-numeric (A-Z,0-9) characters and a single "."
(Even worse, 8.3 for DOS systems but most things are beyond that)
There may be a way to create a file object (which is not the same as
creating the file) but that may not provide the final check for you.
