Regex doesn't match when test string is in middle of fileHi Everyone,
I am using a regex to check for a string. When all the file contains is my test string the regex returns a match, but when I embed the test string in the middle of a text file a match is never returned. The string that I give to the regex is one that contains the entire contents of a text file. I'm using the multi-line option and I've also tried stripping out the VbCr and VbLf's and replacing them with an " ", nothing helped. What am I missing? Thanks, Chris Chris,
Without posting your expression it would be impossible to answer your question. I would recommend downloading RegEx Designer.Net by Chris Sells. It is an excellent tool for testing your expressions. Attached is the GotDotNet workspace url. http://www.gotdotnet.com/workspaces/workspace.aspx?id=01e0dfb7-0182-45cd-94f7-2ed2df2504a9 Look at Chris' site for a screenshot. http://www.sellsbrothers.com/tools/#regexd Jared Show quoteHide quote "Chris" wrote: > Hi Everyone, > > I am using a regex to check for a string.

I'm using Regex Buddy right now for testing. I also already have Expresso, The Regulator, and the RegEx Designer...I've been going crazy trying to get some help. Dim ssnRegex As String = "^(?!000)([0-6]\d{2}|7([0-6]\d|7[012])) ([ -])? (?!00)\d\d([ -|])? (?!0000)\d{4}$" Dim options As System.Text.RegularExpressions.RegexOptions = System.Text.RegularExpressions.RegexOptions.Multiline Dim oSSNRegex As New Regex(RegExTypes.ssnRegex, RegExTypes.options) Inside Regex Buddy, or any of the others, if I use their method to import the text from a test file everything works great and the RegEx returns a match. However, when I view the debugger in Visual Studio and take a look at the string I see all of the square like VbCrLf's in with the string that represents the file I'm testing. If I paste the string that represents the file I'm testing from the watch list in Visual Studio to Regex Buddy, or any of the others, the RegEx fails to make a match. Additionally, I've also tried replacing all of the VbCr and VbLf's with just a blank space " ". Here is a representation of the filecontents I'm looking at (from inside the Visual Studio debugger). I've replaced all of the actual VbCrLf's with readable values: FileContents = "Microsoft (R) Windows Script Host Version 5.6vbCrLfCopyright (C) Microsoft Corporation 1996-2001.
