[Guest]

hi,
i'm a newbie to regex....

i need to check if a given string has more than two occurences of . in the
begiining of string

for ex, if string has value .test is valid but ..test is invalid

Can you help me out with the pattern for such strings?

match patterns:

^[.]{2,}\w+
[if a given string has more than two occurences of [dot] .]

^[.]\w+
[if string has value .test is valid but ..test is invalid]

This would acheive the same thing, but without using regular expressions.

If String.StartsWith(".") = True And String.StartsWith("..") = False Then
'String starts with only one period.
Else
'String starts with no periods or starts with more than one period.
End If
