Hi guys, I'm having a little problem here, I want to validate an entry in a text field using the regex pattern "\d{10}". the said field should have exactly 10 digits, but my application is accepting all entries matching 10+ digits :-( What should I do? -- Everyone's days are numbered. It's called a calendar
Never mind, I used if (!match.Success || txtAccountNum.Text.Length != 10) throw Exception else Endelea() On 3 March 2010 14:14, Simon Mbuthia <simon.mbuthia@gmail.com> wrote:

the posix regex for 10 digits looks like this : [0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]
Thats a handfull. Perl Regex (which I believe .NET implements) would be /[0-9]{10}/ ... And to be absolutely sure : /[0-9]{10,10}/ Its also possible that the slight differences between these regex engines is the reason our good friend was pulling at his hairs. -- Ndungi Kyalo biblia.kenya.or.ke On Wed, Mar 3, 2010 at 11:44 AM, <ashok+skunkworks@parliaments.info<ashok%2Bskunkworks@parliaments.info>

The regex you have is right. But it is also wrong \d{10} means a number with 10 digits. A number with eleven digits also has ten digits. If you mean that you want a string with exactly ten digits the regex you want is this one ^\d{10}$ On Wed, Mar 3, 2010 at 3:08 PM, Ndungi Kyalo <ndungi@gmail.com> wrote:

Thank Conrad... but I think the engine is the one that's wrong, coz what would then be the difference between ^\d{10} and ^\d{10,} ? On 4 March 2010 00:27, Rad! <conradakunga@gmail.com> wrote:

There is nothing wrong with the engine. It is perfectly correct. But you have to be very specific how you explain what you want or your intentions will not be understood. ^ and $ are very important because they signify that the regex should start matching from the beginning of the string to the end. Which is why \d{10} and ^\d{10}$ work differently Given the following strings 1234567890 12345678901 123456789012 1234567890134 \d{10} will match all of them because it means look for strings that have 10 digits following each other. If you want it to find COMPLETE strings that with with 10 digits following each other use ^\d{10}$. This will only match the first string On Thu, Mar 4, 2010 at 9:58 AM, Simon Mbuthia <simon.mbuthia@gmail.com>wrote:
