Solved: (Regular expression for) checking correct file name

[Lammutaja]

Hi!
Can somebody give me regular expression (for Microsoft VBScript Regular Expressions 5.5) for checking correct name of file being saved in Windows XP Proffessional?

User will enter only first part of file:
For example user is saving new file with name "ThisIsmyfile.pdf".
User will enter only "ThisIsmyfile" and task is to check is this string correct for file name.

J?ri.

Hi J?ri,

I'd be glad to help you, but honestly I'm not sure what it is you're asking. What do you want to verify? What exactly do you mean by:

User will enter only "ThisIsmyfile" and task is to check is this string correct for file name.

How do you define correct/incorrect for a file name?

do you mean to check for valid characters?
I think there may something in the kb for that (!?)

J?ri,
The following function should work exactly as you need:[vba]Function ValidFileName(ByVal TheFileName As String) As Boolean
Dim RegEx As Object
Set RegEx = CreateObject("vbscript.regexp")
RegEx.Pattern = "[\\/:\*\?""<>\|]"
ValidFileName = Not RegEx.Test(TheFileName)
Set RegEx = Nothing
End Function[/vba]Matt
