Hellow everyone...
i have to validate a my folderpath field...
could you people suggest any reqular expression to validate a valid
path...
that field should not accept input like “My Documents”
but should accept “c:\Backup”
i searched the web and i tried this...
Regular Expression:
^((([a-zA-Z]:)(\\{2}[a-zA-Z]+)(\\{2}\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}))(?=(\\(\w[\w
]*)))(\\\w[\w ]*)*)$
.but was not usefull...
pls favour for me...
Thanks for any helps

No spaces, no special characters, absolute paths only, something else ? Also what about platforms where paths are delimited in different ways ? What will you be doing with this path ?

You''ll have to give the client a download link and let the browser program take care of saving it OTOH, if this is on the server side, you can construct the path in a way that you know will be valid. In either case, there is *no point* to the validation you''re trying to do.> and i m on windows ...Doesn''t mean your clients will be, so you can''t only accept Windows-style paths! Really, there''s no validation that can do what you want here.
