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 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!

View 1 RepliesI'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 need to construct a regular expression for the password textbox, Min:8,Max:16 and must include atleast a number(0-9),alphabets upper and lower case. I am unable to limit the length to 16.
<asp:RegularExpressionValidator ID="RegEx" runat="server" ControlToValidate="Password"
ErrorMessage="Password must be min:8,max:16 characters and include a number,alphabets upper case and lower case.
"ToolTip="Password format is not correct"
ValidationExpression="^(?=.{8})(?=.*d)(?=.*[a-z])(?=.*[A-Z]).*$">
</asp:RegularExpressionValidator>
I need to construct a regular expression for the password textbox which shouldn't accept special characters($,@,!,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 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'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 also want to add to the expression the text that I pre-populate in the txtbox ("Enter your email address") so on postback, after sending the message, I can clear the fields and repopulate that box.
How do I add that wording to the current expression: w+([-+.']w+)*@w+([-.]w+)*.w+([-.]w+)*
I am using Regular Expression validator for a text box. The below is working fine.It is not performing validation when I enter values like 0000..001.How can I modify validation expression? But it would allow values like 100,...5000 i.e zeros after a number.
<asp:RegularExpressionValidator ID="reg2" runat="server" ControlToValidate="rng2"
ValidationExpression="^[0-9]+" ErrorMessage="*Please Enter a Valid Number for Second Range."
ForeColor="Red" Font-Bold="True"></asp:RegularExpressionValidator>

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.
I have one field in database Mobile No.
In that I want to put validation which accepts "+" and numbers that is not more then 15.
And in that "+" should at the first place in value.
I got this code from a regular expression library to get the src of the image found in a given input. However I can't get it to work because the double quotes(") in the regular expression is closing the string under the second parameter for the .Match function. I tried changing double quotes(") to " but it doesn't work too.

If i am giving the text
hjghj bvgfh . it is failing
This expression is to check number > 1
^[1-9]+[0-9]*$
what is the expression to check if it's greater than a given value, say "99" ? what about a value less than, 99?
Update:
I'm using ASP.NET validation control.
I currently have this regular expression for a whole number with optional decimal to 2 places.
I need to change it so that the number has to be greater than 1.
Code:
[0-9]+(.[0-9][0-9]?)?
