Create Regular Expressions from a string programmatically

Posted By:      Posted Date: April 10, 2011    Points: 0   Category :WPF

I have a situation where users can set up masks for items such as phone numbers or postal codes.  Behind the scenes in the program the mask is applied to these data values as appropriate so they can be displayed in message boxes or labels.  So for example, a user can save a mask for a phone number to be (###) ###-####, or a Canandian postal mask of &#& #&3 (Example Toronto postal code M4B 1B3).  As you can see from the two masks that # represents numbers and & represents characters.  Is there a way programmatically (VB would be nice) that you can take a mask similar to these and turn it into a regular expression pattern so the mask can be applied to a value?

Programmatically create an InfoPath form


I'm programmatically creating an InfoPath form using this article: http://www.bizsupportonline.net/infopath2007/programmatically-create-infopath-form-console-app.htm.


Everything works well up to 29 fields (my:field1 ... my:field29). After that it runs without an error and posts a form to the library however the icon does not switch to an infopath icon and the filename stays blanks. I don't believe this field specific, it seems to be happening when I use any 29 to 30 fields so I'm thinking its a memory issue with the stream reader.

Has anybody every had this issue before, is there a way to fix this?

Combining email and numeric regular expressions

Hi, I am using the following regular expression within an XSD to validate a combination of email ID's and six digit employee ID's separated by a semicolon (;). for example : vedansh.mm@fgfgfg.com;ghgh@ff.com;333333;555555 ^((\s*;?\s*[0-9a-zA-Z_]([-.\w]*[0-9a-zA-Z_])*@([0-9a-zA-Z][-\w]*[0-9a-zA-Z]\.)+[a-zA-Z]{2,9})+\s*(;\d{6})*)*$ It works for the following vedansh.mm@fgfgfg.com;ghgh@ff.com;333333;555555 but does not work when the six digit number preceeds the email, like below 222333;vedansh.mm@ct.com;ghgh@ff.com;333333;555555;fhfhf@gggg.com or if the input contains only numbers, like 555555 What am I doing wrong. The numbers and email address count may or may not be the same. Thank you for all your help Vedanshu
