Make sure you have rows. Do like:

if(dt.Rows.Count > 0 )
{
   ar.Add(dt.Rows[0]["EmailColumnName" OR Index no].ToString());
   ar.Add(dt.Rows[0]["FaxColumnName" OR Index no].ToString());

   if( ar[0].Contains("@") )
       //Bind Array2
 }

If you are looking something else then let me know.

SQL Server Enterprise? You're running a server OS on your development machine?

All you need is SQLExpress. If you look at the machine.config you will see the default connection string is to a SQLExpress instance.

I know the language. I've read a book. - _Madmatt

Assuming that you have to attach the mdf as a static file in your project due to licensing on the SQL Server or for some other reason can't deploy the MSSQL server to your deployment environment, you should perhaps look into using SQLLite and not MSSQL. Clickey

thanks for your reply, guys.
i have done the following steps:
I installed VS2008 and MSSQL2008;
I design database and its table in SQLServer2008.
I don't installed SQLExpress.

now, I am developing an MVC Web Application;
the problem is when right click in App_Data folder and choose existing item to add the created database in SQLServer2008, get this error: Access Denied.
Could you please tell me what is the problem? is there any solution to remove fix this error without installing SQLExpress?

SQl Express is not an answer. Your problem is that you cannot connect a db the way your are trying to. You have to create objects that connect with the SQL Server. You are getting Access Denied because SQL Server owns and controls the file.

XML deserialization

Hi All,

I have XML string as below. I am trying to deserialize this xml string in to a Request Object or NewHire Object. I have designed the Request class as it holds
the instance of NewHire class as a public property. I did in two ways

1. First time when I tried for the Request type it was giving exception like error in identifying property NewHire.

2. Then I deleted the Request element from the xml and kept from NewHire to /NewHire part only and then tried to deserialize the object for the NewHire type.
Then its not giving the exception but all the values in the NewHire instance it is giving null. Its not reading the values.

XML File :
----------
string strXML = "" + "<Request>" + "<NewHire>"
+ "<CompanyCandidateCode>CandCode</CompanyCandidateCode>"+ "<SSN>SSS</SSN>"
+ "<LastName>6456</LastName>"+ "<FirstName>3434</FirstName>"
+ "<MiddleName>676</MiddleName>"+ "<EthnicGroup>546456</EthnicGroup>"
+ "<Address>tuituiu</Address>"+ "<City>dfgfd</City>"
+ "<State>ghjgjg</State>"+ "<Zip>345345</Zip>"
+ "<HomePhone>bvnbvn</HomePhone>"+ "<OtherPhone>234234</OtherPhone>"+ "</NewHire>"+ "</Request>";

Deserialize Code:
----------------
            try
            {
                System.Xml.Serialization.XmlSerializer serializer = new System.Xml.Serialization.XmlSerializer(typeof(Request));
            System.IO.TextReader reader =
                new System.IO.StreamReader(new MemoryStream(ASCIIEncoding.Default.GetBytes(strXML))); 
           
            Request ObjItems;

            ObjItems = (Request)serializer.Deserialize(reader);
                reader.Close();

                string str = Convert.ToString(ObjItems.NewHire.Address);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }

I want to read this in to my Request or NewHire objects any of the above two methods ok. I prefer for the first one to fill the Request ojbect but if it can fill only NewHire
object and cant fill an object containing another object, I will adjust with NewHire only.

Can anybody please help me in this regard as I have to deserialize it in anyway.

RSS Feed Aggregation

I want to create (or borrow if one exists) a "news ticker" for our website that aggregates RSS feeds from vendors and news outlets into a section of our webpage. I want to maintain the functionality of being able to click through to the stories as you would when using an RSS reader. Is there something out there that already exists and I'm just not looking for the right thing? I know I've seen this on other websites and was just wondering if this is something that every website has developed on their own? Any help is much appreciated, thanks!

When I don't pass certain value in textbox. It gives me above exception.
Here's the code.

cmd.Parameters.Add("DOB", SqlDbType.SmallDateTime).Value = txtDOB.Text;

I want to ignore NULL values. How to tackle this problem.

I know it should have been easy. But anyhow, I stuck .

If the value in txtDOB.Text is a null or whitespace character, you need to set Value to DBNull.Value.

thanks for quick response.

So to my best understanding, I can replace

old phrase

cmd.Parameters.Add("DOB", SqlDbType.SmallDateTime).Value = txtDOB.Text;

with this one

cmd.Parameters.Add("DOB", SqlDbType.SmallDateTime).Value =  (string.IsNullOrEmpty( txtDOB.Text)) ? DBNull.Value.ToString() : txtDOB.Text;

Is there any way shorter to do this.

I normally use a utility method like this:

public static object GetValueForParameter(string value)
{
  if (!string.IsNullOrWhitespace(value))
    return value;
  return DBNull.Value;
}

Then you can replace your code with cmd.Parameters.Add("DOB", SqlDbType.SmallDateTime).Value = Utility.GetValueForParameter(txtDOB.Text);

if u want to do it from codebehind, make your main div to runat="server" so that you can access it from codebehind.
e.g.

my popup content

After the code for inserting a new row executes the very last thing u must now do is to show the modal.
e.g.

public void InsertTableRow()
{
   //here i have inserted a new row into my table..

   //now i will show the updates in a popup modal like so:
   popupModal.Style.Value = "display:block;";
   //watch here, am applying new style for this div on a div-id, which then mean that all your fancy css styles should be appended to your class(e.g. myPopupClass). if u include all your css on your id and u execute the above code to show your modal the css is going to be overwritten....
}

hope that helps...

You can use Open() method of ModalPopupExtender in code behind when new row is added.

Dataset VS SQL Server Database

Hi,
I am developing ASP.net and VS2010; I am using MVC; I right click on Model Folder to choose an Data Model; just wondering to know what is difference between Dataset and SQLServerDatabase?

Re: Dataset VS SQL Server Database

Dataset are inmemory objects, these are used to store data (in table form).We fetch data from the databse, fill it in databse. Now we do our manipulation in the dataset and show the results accordingly. .NET provides the facility to do most of the opertaion that we can do with database table. We use dataset , when there is low no records in resultant table.

While SQLServerDatabase, we store in database. Ther are stored in files at harddisk.Obusly we have bit more flexibility over dataset. If number of records are higher, we use databse for all the manipulation..
