File Name Validator

[Brahm]

Hi Folks,

do you know a file name validator ?

I am reading a text file and I am creating new files in runtime. In some
cases it is found string with invalid characters so. I
have errors.

I was able to avoid the problem with this character "/"

Is there anything peace of code already ready for this ?

Any help is appreciated.

Thanks.

Hi,

Use a regular expression.

dim rFile as new
regex([A-Z]:\\[^/:\*\?<>\|]+\.\w{2,6})|(\\{2}[^/:\*\?<>\|]+\.\w{2,6})")
if rFile.isMatch(strFilename) then
'you have a valid file name
end if

Brahm,

You can use the System.IO.Path class.

Path.GetFileName will throw an exception if the filename contains invalid
characters.
