Dec 6, 2010I've been hammering at this over the weekend with no joy - been through page after page of RegEx Language documentation too.It's very easy to negate a match on characters. For example:
Dim MatchString As System.String = "<test0><test0><test1></test1></test0></test0><test0></test0>"

View 2 RepliesRegex.Replace Not Working?
Aug 15, 2011I am trying to replace text in my xsl file. I have to replace all the http and https. But I can leave any links that start with <a href>
Ie; http://www.google.com has to replaced. But < a href="google.com">google.com</a> has to remain as it is.
I am using regex to find all the http(s) and a hrefs in the text. I am struck here.
My code is,
Dim href As New Regex("(<a.*?>.*?</a>)", RegexOptions.IgnoreCase)
Dim hrefs As New Regex("http(s)?://([w+?.w+])+([a-zA-Z0-9~!@#$\%^&*()_-=+\/?.:;',]*)?", RegexOptions.IgnoreCase)

I am trying to use Regex.Replace to replace my https. But I am unable to write the evaluate function.
My regex.replace replaces all the values with a single value.
HTML Tag Replacement Regex Not Quite Working Correctly?
Sep 14, 2009This is a follow up to another question of mine.

Mar 4, 2010I am pretty good with perl regular expressions but evidently I am at a loss on why this doesn't work.The code below stores "Person Test" in output variable.
im output As String
Dim userName As String = "Test, Person"

View 3 RepliesConcatenating A Variable With A Regex Group Match In Regex.replace?
Apr 5, 2012I am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].

This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?

Regex Builder That Actually BUILDS RegEx From A Highlight
Nov 17, 2011I've been working straight since yesterday trying to get this to work.

VS 2008 Cannot Seem To Get A Working Filter In Working Order
Jun 18, 2009It appears that my favorite thing in the world is tackling projects that are beyond my current knowledge and abilities. I have a little project that I am working on which is a simple image viewer stocked with (upon completion) your standard Load..., Next/Previous, Zoom In/Out, Actual Size, and Full Screen capabilities. However, I am running into a few snags:
(1) I've been able to get my "Load..." button to display a file dialog box, but I cannot seem to get a working filter (with which only image file types are allowed to be selected) in working order.
(2) I have a PictureBox object (entitled PictureBox1) that displays the image selected via the file dialog box, but it loads images in their full size (1:1/100% zoomed) state without scrollbars, etc. to allow me to navigate the loaded image. I would like to have it load the image, initially, to fit within the dimensions of PictureBox1 and from there be able to zoom in/out via my "Zoom In/Out" and "Actual Size" buttons and be able to scroll if the zoom level is beyond the dimensions of PictureBox1.
(3) It dawned on me that I haven't the faintest idea how to get my "Next/Previous" buttons to allow the user (me) to navigate, in succession, the images contained in the folder in which the currently loaded image is stored. [code]
