By Chris Malek | Wed, Nov 16, 2016
This function uses a REGEX to validate an email pattern. The java REGEX came from emailregex.com.
Function IsValidEmailPattern(&emailIn As string) Returns boolean
Local JavaObject &jCheckEmailRegex;
Local JavaObject &jInput;
/* source http://emailregex.com */
Local string ®exString;
®exString = "(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*|";
®exString = ®exString | Char(34);
®exString = ®exString | "(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21\x23-\x5b\x5d-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])*";
®exString = ®exString | Char(34);
®exString = ®exString | ")@(?:(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?|\[(?:(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.){3}(?:25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?|[a-z0-9-]*[a-z0-9]:(?:[\x01-\x08\x0b\x0c\x0e-\x1f\x21-\x5a\x53-\x7f]|\\[\x01-\x09\x0b\x0c\x0e-\x7f])+)\])";
&jCheckEmailRegex = CreateJavaObject("java.lang.String", ®exString);
&jInput = CreateJavaObject("java.lang.String", lower(&emailIn));
If &jInput.matches(&jCheckEmailRegex) Then
Return True;
Else
