Regex - .NET: Manipulating TextBox Input: Dash Every 5 Characters And Removing Special Characters?

Dec 21, 2011

Essentially I am trying to replicate the Windows 7 (In-Windows) activation key TextBox form. The Form where it will auto capitalize letters, remove or deny all non alphanumeric characters except dashes every 5 characters that will be auto-input.I assume this can be done with a fairly complicated replacement Regular Expression but I cannot seem to create one to fit the needs.

This is an Example of what I have right now, but it creates an infinite loop as it removes all characters including dashes, than adds a dash, which changes the text and removes the dash again.

Way To Disable Numeric Characters

Nov 11, 2009

Well, it's really my first time to try Visual Basic .NET, then I realized that not all my previous experience with VB6 will work smoothly in VB.NET. I am creating a simple program that will enter a name in the TextBox and will greet them by using the MessageBox class. But I wonder, since the TextBox that I'll be using is for inputting a name, I want to "trap" all numeric keys in my keyboard, I just don't know how to do it. This is fair easy in VB6, using the Text1_KeyPress(KeyAscii As Integer) subroutine.

Check If A String Contains Characters Other Than Numeric?

Jul 7, 2009

is there a way to check if a string contains characters other than numeric? ive used isnumeric quite a bit and its pretty usefull, but cant find a way to check for text in a string. Having searched around theres a few ways of doing it slowly that ive found using an array of letters and a loop / instring, but thats much more hassle than checking for numbers, so strikes me there must be a way.

Highlight Numeric Characters In A Maskedtextbox?

Apr 14, 2011

I am using a masked text box to allow users to enter a serial number. The problem is that this serial number has to be communicated over the phone and people seem to be having trouble differentiating between O and 0 and I and 1.

I thought that a good solution to this might be some way of highlighting which characters in the textbox were numeric characters (as opposed to alphabetic characters). Obviously there is no way to do this without using a richtextbox and then I lose the masking ability. Highlight numeric characters in a maskedtextbox?

is there any function to validate if a string has only numerical characters? I can cross character for character and verify if it is a number. But I look for something simpler or if already a function like that exists.

I cannot use IsNumeric or IsDigit because it returns numbers to True with point or comma.

Using Regex To Extract Between Two Characters?

Sep 4, 2011

Im trying to extract ALL urls from a webpage in between two sets of strings.

I have the code to extract all links, but I am

href="http://www.blah.com/yadayada?tf=info"

Using regex; I want to grab everything between href=" and the quotation mark at the end .

This was a snipit I found that works for extracting in between 'href="' and </a>

HTML

Regex.Matches(data, "href=""(.*?)"".*?>(.*?)</a>")

I learn best by example, and I tried piecing it together by comparing the regex match above, to a URL in between hreft" and </a> - but I couldnt do it. Ive been working on this project for a while, and im getting tired.

Replace Characters Inside Parenthesis Using Regex?

Sep 30, 2010

To search a pattern containing parenthesis, they must be escaped using backslashes. So to search for (Streetname) you must use (Streetname). If you don't use , whatever is between () will be retained and available for reference through the variables $1, $2 etc... Exemple, in the sentence "It's worth noting that (StreetName) can be anything...(Post), (TreeStump)", $1=StreetName, $2=Post, $3=TreeStump

Regex - .NET Regular Expressions, Matching Escape Characters?

Dec 3, 2010

I want to use Regex.Replace to replace a Match with a context sensitive value. I use the MatchEvaluator for this. But to make things simpler lets say I'm matching %v I want %v to be escapable, so if I use \%v it will not match. Anything else should match.

The pattern I came up with is this: (?:[^\]|^)%v It basically matches %v if it occurs at the beginning of the string, or if it follows any character except . It doesn't capture the first part of the expression.I know this isn't the "right" way to do it. But it worked just fine until I noticed that when I use this pattern in a replace, it includes the character before %v in the replacement(duh, right?)So, if I have ThisIsAValue:%v and I do Regex.Replace, replacing with the string Value, my result will be ThisIsAValueValue instead of ThisIsAValue:ValueI've tried googling this but the fact that "escape character" is so heavy in RegEx, all the results are geared towards the USAGE of escape characters instead of picking them out with a pattern.

Regex Replace All Characters In Variable Length String?

Oct 6, 2010

Using VB or C#, I am getting a string of variable length from the database. This information is sensitive information that only certain users will be able to see.I have two cases that will use the same logic (I think).scenario 1: replace all characters with xscenario 2: replace all characters with x except the last 4 characters (assume length > 4 - this check is being done).I thought that this would be easiest using Regex.Replace(input, pattern, replacestring). As opposed to a lot of string handling with substrings and forcing a length of 'x's.
