I have seen several examples in Flex for passowrd validator using RegExp. But every where the validation is happend for single validation.

I have a requirement, like password validations like

• At least one Upper case letter

• At least one numeric character

• At least one special character such as @, #, $, etc.

• At least one Lower case letter

• password lenght minimum 6 digits

• password cannot be same as user name

Can anyone provide me a code for this..? I have the code only for checking the password is valid or not . check the below code.

MXML CODE

<mx:FormItem label="Username:" x="83" y="96" width="66">
    </mx:FormItem>
    <mx:FormItem label="Password:"  x="88" y="123"  width="61">
    </mx:FormItem>
    <mx:Button label="Login" id="btnLogin" tabIndex="2" click="login();" enabled="{formIsValid}"  x="327" y="162" width="84"/>
    <mx:TextInput id="txtPassword" displayAsPassword="true" change="validateForm(event);"   x="152" y="121" width="217"/>
    <mx:TextInput id="txtUserId" change="validateForm(event);"  x="152" y="94" width="217"/>

AS Code:

private function validateForm(event:Event):void 
{                    

    focussedFormControl = event.target as DisplayObject;         
    formIsValid = true;            
    formIsEmpty = (txtUserId.text == "" && txtPassword.text == ""); 

    validate(strVUserId);                
    validate(strVPassword); 
}

 private function validate(validator:Validator):Boolean
 {                

    var validatorSource:DisplayObject = validator.source as DisplayObject;
    var suppressEvents:Boolean = (validatorSource != focussedFormControl);
    var event:ValidationResultEvent = validator.validate(null, suppressEvents); 
    var currentControlIsValid:Boolean = (event.type == ValidationResultEvent.VALID);

    formIsValid = formIsValid && currentControlIsValid;

    return currentControlIsValid;
  }
