I need to construct a regular expression for the password textbox which shouldn't accept special characters($,@,!,etc).Even whitespaces,tabs. I tried the below this accepts special characters.
<asp:RegularExpressionValidator ID="RegEx" runat="server" ControlToValidate="Password"
ErrorMessage="Password must be atleast 8 characters and include a number,alphabets upper case and lower case.
"ToolTip="Password format is not correct"
ValidationExpression="^(?=.{8})(?=.*d)(?=.*[a-z])(?=.*[A-Z]).*$">
</asp:RegularExpressionValidator>

I'm looking to validate the length of a textarea using a regular expression validator. It should allow all characters and crlfs. I'm also concerned about crlfs counting as 1 or 2 characters, I'm concerned it may be different across browsers but I'm hoping ASP.NET regulates it. Also, I'm saving to a mix of varchar and nvarchar fields in MSSQL, do I need to be concerned about the way crlfs are saved there? I'm in a hurry to do this right, so I'll be researching all this on my own but I'm just hoping someone out there might have experience handling such concerns.

I have custom control for create user. I use RegularExpressionValidator with expression (?=W{1,}){7,} (lentgth min 7 character and must include not less 1 NotAlphaNumeric character) . I test this expression
function GetText(AInputText) {
var VRegExp = new RegExp(/(?=W{1,}){7,}/);
var VResult = VRegExp.test(AInputText);
return VResult;
}
it's work. But RegularExpressionValidator doesn't accept this expression for input - 1234567! or 12345qwer!

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>

I would like to create a regular expession for my login password validation (membership -> provider) but can't find an example anywhere that meets my needs.I would like to require that the paassword begin with an alpha character, contains at least one a-z, one A-Z and one 0-9. The password must be at least 8 characters long but I don't believe that needs to be in the regex.

I am using regex for server side validations.
I am facing a problem with regex. I want to check for sepecial characters like ><*&()%$@!~+...
I need to filter these special charecters...but the problem is in my 10 textboxes there only 3 are required...
I can submit the form without entering anything...but my regex is not allowing me to submit the form without giving a space from keyboard...
I just want to check for special charecters and empty textbox without giving a spacebar...
I just check these sites(http://regexlib.com/ and http://www.regular-expressions.info/) and read some documentation on regex...its kind of confusing....
Here is my regex for Middlename: ^[a-zA-Z''-'s]|[ ]{1,40}$ its worked but its not correct....then I changed it to ^[a-zA-Z''-'sd*]{1,40}$ this also not taking emptytextbox without giving a space...
My Goal:
In most of the textboxes I need to allow only numbers and - # _ in some textboxes....
For Address: need to allow alphabets and numbers and #-_' "
City: numbers and alphabets no special chars...
Main problem is I can write regex for most of these stuff but need to all textboxes without entering anything (empty textboxes).My work got stoped due to this.

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've tried many ways to solve the problem that my professor gave me but my knowledge isn't that enough to solve this problem..

I need a way to create a regular expression from a string or an array of domain names. for example string array = [URL]. Once I click save I would want to create a regular expression that would match all 3 with or without '.com' extension. Then Another task would be to pull this data out of regular expression and put it back into an array.
