I'm using RegularExpressionValidator controls to impose password rules when creating new passwords. I want to avoid repeatitons such as 'aaaa' or sequences such as '12345' in the password.
How do I write the validationexpression to a RegularExpressionValidator to impose this rule? I do not want to do thing using C#, just with a regular expression that could be put within the validator control like below:
<asp:RegularExpressionValidator
ID="RegularExpressionValidator3"
runat="server"
ErrorMessage="Password
should contain Minimum 8 Characters"
ControlToValidate="txtPwd"
ValidationExpression="w{8,30}"><asp:RegularExpressionValidator>
Regular expression validator  for not acception special characters and space.
View 1 RepliesThere may be an easier way, and if there is I'm all for it. However - my ASP.NET page has a TON of controls on it, and I've given them all ID's that start with underscore. I copied all the markup into Notepad++ and I'm trying to find a regular expression that will find everything but the controls and replace it with whitespace. that way I'll have a text file that has all my control names which I'll probably throw into Excel and do some string manipulation to add ".Text = " etc.

I am now trying to remove them globally.

i have to check if an input string is valid based on the given regular expression.. this is the regular expression.
(a(bb+aaa+((ab)*bb+(aba)*aa)(a+b)*) + (b(aa+bbb+((ba)*aa+(bab)*bb)(a+b)*)
+ is an OR
* is a LOOP, it is optional, it may be done as many as a user wants.

I'm trying to use the validator to work on a email form to ensure that they enter a valid from email address. That part works.

I am using a regex to detect forum tags within posts, such as "[quote]text[/quote]" and then replace them with HTML formatting. I posted a question Forum tags. What is the best way to implement them? about a problem with nested tags.
I need this regex modified
string regex = @"[([^=]+)[=x22']*(S*?)['x22]*](.+?)[/(1)]";
Right now this matches an opening and closing tag, with match groups for the tag name, the tag content, and an optional value like the value after the equals in this forum tag [url=www.google.com]click me[/url].
What I need is for the expression to match the opening tag OR the closing tag and have a match group containing the tag name (including the '/' for the closing tag). I then want to iterate through them sort of like this:
Dictionary<string, int> tagCollection = new Dictionary<string, int>();
inputString = Regex.Replace(inputString, @"expression I'm asking for here",
match =>
{
[Code]....
So now, each tag is appended with a number and I could use the original regex to perform the tag functions and properly handle nested tags as separate tags.
