Verifying if a ascii file

[Kori]

I am trying to find a procedure or function in Visual Basic that will go and look at a file and tell me if it is a valid Ascii file. Can anyone help????

What is your definition of " ... a valid Ascii file ... "?

I mean a valid ascii file by saying it is not a binary file.

Hmmmmmmmmmmmmm,

Interesting ... v e r y I N T E R E S T I N G!

I know of NO function to seperate files by such a distinction. It "could" - with some real definition of what you mean by an ASCII file be done fairly trivially.

I would Propose{/b] such a definition:

All bytes within the file be:
Between Chr(32) And Chr(94) OR
Between Chr(97) And Chr(126) OR
Equal Chr(10) OR
Equal Chr(12) OR
Equal Chr(13)

IF this definition - or some 'reasonable' (e.g. logically consistient) alternative is acceptable, I'm sure a 'quick and dirty soloution' can be generated. BUT, you will almost certainly be waiting for such a routine to verify a "Large" file fits such a definition (but probably not very long to find that it does NOT fit the definition).
