Validation Using Regular Expressions?
Jun 24, 2011I'm trying to do is some password validation. It needs to have at least 1 lower case character, 1 uppercase character, 1 number and at least 6 characters in length. I figured I could do this using "RegularExpressions" however I can't figure out how to determine the "at least one occurance" of each. For example I thought the following would work but it only validates that what is input is a lower case, uppser case or numeric character, not that the input has at least one of each. The user should be able to enter any characters but at least one of lower case, upper case and numeric characters.
Dim
myMatch
As
Match

C# - Using Regular Expressions To Get A Word In Between Two Key Words?
Jul 27, 2009It has been a while since I have used regular expressions and I'm hoping what I'm trying to do is possible. I have a program that sends automated response regarding a particular file and I'd like to grab the text between two words I know will never change. In this example those words are "regarding" and "sent"
Dim subject As String = "Information regarding John Doe sent."
Dim name As String = Regex.IsMatch(subject, "")
So in this case I'd like to be able to get just "John Doe". Every regexp I'm coming up with includes the words "regarding" and "sent". How can I use those words as the boundaries but not include them in the match?

Regular Expressions - Show First Match Only?
Sep 11, 2010I'm trying to use regular expressions to find a matching model within the game. This part works perfectly! The only problem is that if it finds more than one match it'll try to place all matches it finds which I don't want it to do. Anyone more advanced in Regex can they tell me how to use regular expressions to only show one match or the first match it finds?
If Messege.ToLower.StartsWith("^place model") Then
Dim Regex As String = Messege.Remove(0, 13)

Regex - .NET Regular Expressions, Matching Escape Characters?
Dec 3, 2010I 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 - Separating Text From Numbers Using Regular Expressions?
Nov 7, 2010I'm having trouble parsing some text. Here's an example of the text:

705 W 1 PC 0.000 135.000 0.295 39.825 0.000 0.000 135.000 0.000
2106 ONL 9.99 41.141 3.000 4.110 12.330 3.000 0.000 0.000 29.970
Here's the latest incarnation of the code I've been trying:
objInfo = System.Text.RegularExpressions.Regex.Split(
newLine,"(d{3,5})|([0-9]+[.]+[0-9]+)|(w*)")
I'm having trouble because I'm avoiding getting many blank spaces in the array after splitting. I'm trying to avoid using the optional | character but I get no results when I set it up without it!
I've spent much of the evening reviewing regular expressions and I've downloaded the following programs:
