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)?
I want to be sure a user only enters alphabetic characters for a field that accepts strings. They should only be able to enter a-z, no numbers. Can the minimum and maximum values be set to a and z, respectively?

I'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.] System.Web.UI.WebControls.SqlDataSourceView.ExecuteDelete(IDictionary keys, IDictionary oldValues) +1648440 System.Web.UI.DataSourceView.Delete(IDictionary keys, IDictionary oldValues, DataSourceViewOperationCallback callback) +89 System.Web.UI.WebControls.GridView.HandleDelete(GridViewRow row, Int32 rowIndex) +714 System.Web.UI.WebControls.GridView.HandleEvent(EventArgs e, Boolean causesValidation, String validationGroup) +869 System.Web.UI.WebControls.GridView.RaisePostBackEvent(String eventArgument) +207 System.Web.UI.WebControls.GridView.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument) +10 System.Web.UI.Page.RaisePostBackEvent(IPostBackEventHandler sourceControl, String eventArgument) +13 System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) +175 System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +1565
The equvivalent error message appears when I klick on the "Edit"-Button... How do I have to specified the Delete and EditCommand?
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?

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...
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:
