Webaddress = WebAddressField.value // WebAddress is a TextField As previously said, these are not silver bullets Р В Р вЂ Р В РІР‚С™Р вЂ™Р’В¦ but there is a good chance that most of the wrong cases are caught and returned as not valid.Р В РІР‚СњР В РІР‚РЋor example, you can use them like this: Var email, webaddress As StringР В РІР‚СњР вЂ™Р’В®mail = EmailField.value // EmailField is a TextField Once done, you can start using these new method extensions to validate the input data from the user. Rx.SearchPattern = '^(http://Var match As RegExMatch = rx.Search(Value)Р В РІР‚СњР В РІР‚С›s you can see, we are using the same technique here, changing the pattern string we are using for the search of a valid URL address in the data provided as Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўsourceР В Р вЂ Р В РІР‚С™Р РЋРЎС™.

Then, put the following snippet of code in the associated Code Editor for the Method: // Some previous text cleaningР В РІР‚СњР В РІР‚С›s you can see from the code, it uses the power of Regular Expressions to search the expected format for an email address if it returns a match, then that means that we are dealing with a valid email address.Р В РІР‚СњР В РІР‚С›dd now the second Method and name it Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўValidatedURLР В Р вЂ Р В РІР‚С™Р РЋРЎС™, using the following signature in the Inspector Panel:Р В РІР‚СњР В РІР‚С›nd put the following piece of code in the associated Code Editor: Value = Value.Trim LetР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s name the first of these methods as Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўValidatedEmailР В Р вЂ Р В РІР‚С™Р РЋРЎС™, using the following signature in the Inspector Panel:

So, the first thing is adding a new Module to your project (you may name it Р В Р вЂ Р В РІР‚С™Р РЋРЎв„ўString ExtensionsР В Р вЂ Р В РІР‚С™Р РЋРЎС™, for example), and a couple of new Global methods on it.

I want to share with you a couple of String Class extensions you can use to see (and conform) whether the user typed a valid email or URL,Р В РІР‚в„ўР вЂ™Р’В this is not a silver bullet (there are always exceptions), but it can save you some time now and in future projects.Р В РІР‚СњР вЂ™Р’В«efore we start, letР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s remember that a Class extension is a really convenient way to provide additional functionality to an existing class without needing to subclass it. For example, getting a valid email addresses or URL. Often in our projects we need to apply some kind of validation of the user input so we get the data we are expecting.
