ErrorMessage="Password must be atleast 8 characters and include a number,alphabets upper case and lower case.

I've built a web application that employees sign on to and take tests, get certifications, etc. My client wants all employees set up so that their user name is their real name, in the format of "Lastname, Firstname". It doesn't look like MembershipProvider will allow commas or spaces in the user name. Am I going to have to store this in a separate column in another table, or is there a way to tell the provider to accept those characters...
View 2 RepliesI am using Forms Authentication in a new ASP.NET 3.5 Application.I have created the Tables in my database and run the Web Site Administration Too.When I try to create a user I get a password error no matter what I throw at it and I am becoming sure of that this is a symptom of an a setup error and not a password problem.One of the things that I notice is that my aspnet_Applications is empty and I am not sure what is supposed to fill it.I have tried to delete all the aspnet tables and done the procedure again but with the same result.
View 1 RepliesI gave an option to user to change password but the text boxes are taking - / @ (special characters). How to check at runtime that user may not enter these characters?
View 21 Replies1. In the asp.net configuration tool I can create a user without a problem. When I enter the password it performs some validation on it and if I've not entered a reasonably strong password it gives me an error saying "the minimum password length is 7 characters and must contain at least 1 non-alphanumeric character." I've got no problem with this and I don't want to get side-tracked into the merits of password security. Is it possible to change this validation so that it accepts anything I enter? Surely, as weak as it is if I wanted to enter "password" I should be allowed to? Perhaps you can't change it which is fine but if you can how would you go about it?2. If I add an asp change password control to a page I was sort of hoping I might be able to override any global setting (1 above) and find a property that would let me set the pattern at run time? I can't but maybe there is a way to do it in code?

View 1 RepliesI've got a program that in a nutshell reads values from a SQL database and writes them to a tab-delimited text file.
The issue is that some of the values in the database have special characters (TM, dash, ellipsis, etc.) When written to the text file, the formatting is lost and they come across as junk "â„ or â€" etc"
When the value is viewed in the immediate window, before it is written to the txt file, everything looks fine. My guess is that this is an issue of encoding. But, I'm not real sure how to proceed, where to look, or what to look for.
Is this ASCII or UTF-8? If it's one of those how do I correct it before it's written to the text file.
Here's how I build the text file (where feedStr is a StringBuilder)
objReader = New StreamWriter(filePath)
objReader.Write(feedStr)
objReader.Close()
I'm fairly new to ASP.NET and have the following problem:
I add data to an Access database through a form on a aspx.-page. Now my problem is, if the user enters characters like " or & the syntax of the SQL command i send to access changes and the whole thing crashes. :-(
It should nevertheless be possible to write special characters in the Access database. How can I do that??
Seconde question:
I put a GridView under my form to display the data entries from the access database to the user. This GridView has 3 Options in every Line at the beginning (Edit, Delete and Select) by default. OK, when i klick on Delete it comes the following error message (hand-translated from german into english ;-] )
"Deleting is not suppoorted from the datasource "AccessDataSource" unless the DeleteCommand is not specified.
[NotSupportedException: Das Löschen wird von der Datenquelle "AccessDataSource2" nicht unterstützt, sofern nicht DeleteCommand angegeben wurde.]

I'm using the code below to allocate tags in an XMl document into groups using the char[] alphabet below.
This works great for tags that start a-z. However I have some tags in the XML document that can start with special characters (eg 0-9, ! @ # $ & * etc)
I'd like to put them all in one group called "SP". Is there a way to do that?

View 2 RepliesI am creating a site in asp.net with URL rewriting.
My initial url is like /mypage/languagename/ASP.NET
it is working fine when I am excepting taking the language name with
HttpApplication app = (HttpApplication)sender;
app.Request.RawUrl // this is giving me ASP.NET
but when the initial URL is/mypage/languagename/C#
I am getting only C from the rawURL instead of C#.
buildLetter.Append("</head>").AppendLine();
buildLetter.Append("").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
Assume the above contents resides in a file. I want to write a snippet that removes any line which has empty string "" and put escape character before the middle quotations. The final output would be:
buildLetter.Append("</head>").AppendLine();
buildLetter.Append("<style type="text/css">").AppendLine();
The outer " .... " is not considered special chars. The special chars may be single quotation or double quotation. I could run it via find and replace feature of Visual Studio. However, in my case i want it to be written in c# or VB.NET
I have a requirment to filter out all users in the database by starting letter. so we will be having link buttons for A B C D E..... Z. If user clicks on A, all users whose name starts with A is retrieved Now the concern is, if there are users whose name starts with any special chars how they can be classified under any filters OR just copy pasting what the client asked me. In terms of filtering UTF characters, is there no way to set it up so that all 'A' (i.e. Ä, Á etc.) characters are assigned to A (i.e. some way of grouping together in an "if else" kind of rule)?

How to programatically insert string with special characters into RTF? I have rtf template I load to string and then replace all $MY_VARIABLE$ with data. Data contains special chars like 'ąęść' and the problem is that in result file these characters are replaced with '?'. It's something wrong with encoding but what?
My code looks like:
StreamReader reader = new StreamReader("template.rtf");
StringBuilder form = new StringBuilder(reader.ReadToEnd());
// here I replace variables in rtf with data
Encoding srcEncoding = new UTF8Encoding();
Encoding dstEncoding = new ASCIIEncoding();
byte[] utf = srcEncoding.GetBytes(form.ToString());
byte[] asci = Encoding.Convert(Encoding.UTF8, Encoding.ASCII, utf);
return dstEncoding.GetString(asci);

I have to replace XML characters that are being sent to me like this:
Private Balcony & Patios w/Storageto instead be this:
Private Balcony & Patios w/Storage
I want to make sure I have an exhaustive list of all possible characters, so we don't find one later after my programming change.
I was told to do these (by a developer at the client site who is passing me the xml as he gets it from the database and wants me to parse it):
replace all "&" to "&" as well as any of other 3 reserved characters:
">" to "<"
"<" to ">" and
"%" to "%"
But when I googled more infor on XML special characters, I found this list:
& &
< <
> >
" "
' '
Which says nothing about the % but mentions the quote and apostrophe.
So what is the exhaustive list?
I would like to transform an html input to xml. But the input will have as part of its content an "&", e.g. Texas A&M. But calling XslCompliledTransform.Transform(htmldocument, xmlwriter) causes an xmlexception to be thrown.
