What does it mean?

You have to make your own logic. Just send a mail with a link that has the unique identification in its querystring. Now when user activates the link place the active boolean field in the database to true.

Hey this could be done 1000 ways.. So better you make your own logic. Big Grin | :-D

How to put GridView control into edit mode

I've got GridView control consisted of a template and a bound field.
I defined either autogenerated edit buttons, or added the one in item template.
I also added edit template for GridView control.

When I click that edit button as the view is populated with 1 record to edit it, the rowediting evet fires in which I set GridView.EditIndex = e.NewEditIndex

Page post back happen, but GridView does not change that row into edit mode.
Nither item template to edit template nor bound field???

SqlDataReader Problem

Hi All,

I am implementing 3 tier architecture

From the UI

in UI

 MySqlDataReader reader = businessLogic.GetRoles();

        ddRole.DataSource = reader;
        ddRole.DataBind();

In DAl


        public MySqlDataReader ExecuteReader(String query)
        {
 MySqlConnection con = new MySqlConnection((connectionString));

            MySqlCommand cmd = new MySqlCommand(query, con);

            con.Open();

            MySqlDataReader reader =cmd.ExecuteReader();

            con.Close();
            
            return reader;
     }

but when i close the connection reader also get close so that it returns null
how can i solve this probs

This is an expected behavior. When you close the connection, everything is closed with it.

If you really want to create the connection, the command and the reader in the same method, to then return the reader, I think you should implement a wrapper class that also contains the connection.
For example:

The MyReader class implements dispose as:
connection.Close();

And implements the IDataReader interface, making everycall redirect to
[return ]reader.Method([parameters]);

This way, users will still see a IDataReader returned, but when closing the reader the connection (command and reader) are closed.

Another way, more simple, is to return an struct that contains Connection, Command and Reader public acessible... so the calling method can use the reader, and at the end it is responsible for calling Connection.Close().

To summarize :

SqlDataReader required a open connection to read data.

Yes.. Why do you need to show this in browser. Writing excessive data in browser will eat up all the memory of the process associated with the browser. And this leads to hang your browser.

I recommend to do pagination do overcome this situation.

This sounds like an interview question Smile | :)

AFAIK, all four can host .NET apps (I'm doubtful about Windows Shell though)

Actually IIS is the main hosting environment for web applications.
Internet Explorer is the client for the IIS (which is not obviously the host, but client), ASP.NET is the technology, and Windows Shell is the platform.

so if this is your interview question, you need to pick only IIS.

Rich text editor for html code

Abbas_here12-Nov-09 22:50

12-Nov-09 22:50

Hey, this could go one of two ways. I want a rich text editor for my website, the information typed into the text editor will be saved to an sql server database under either char or varchar format that supports up to 8000 characters per field. I want it to save as html code. This content will then be pulled from the database to be displayed in a label. Now my question is, what is a good C# html rich text editor (must be free) OR how can I make one for C# (preferred).

Thanks in advance
Abbas

Check your code. Put break point. Debug it. Check in which line it throws the error. It clearly says that the object that you are using is not found.
