Hi, have a look at the Encoding class, in particular UTF8 property and GetChars/GetString
methods.

I was unaware of class UInt16Converter.

However the MSDN doc says "You should never create an instance of a UInt16Converter.
Instead, call the GetConverter method of TypeDescriptor."

So you may want to modify your code snippet.

So how is your code now? And what does that syntax error says? Mark's code was ok...

change datacolumn position

Hello,

I had a query related to selecting Only few columns from one datatable to another datatable.

I was trying something like this (Using Select query):
string query = "shorttitle,Identifier";
DataRow[] foundRows = dt.Select(query);

But failed as it throws error.
If There is a solution for the above issue to get only few selected columns from another datatable. It will be great.

Alternative to this is Is it possible to change the order of the columns
example

Original DataTable
name, age, date of birth

New datatable

Dateofbirth,name, age.

Please suggest. Tried hard but not working?

Regards,
Pavas

It might be helpful to include the error you are getting, and the code you are using to import the rows into the second DataTable.

You are probably getting something like, "row already belongs to another DataTable". Try this

foreach(DataRow row in foundRows)<br />
{<br />
   newDataTable.Rows.Add(row.ItemArray);<br />
}

Is there any common event for all Editable control in a webform?

My Requirement is : I have a webform with some editable controls and a button.
On Page load event i have given default values to all ediatble controls.

now i am changing data in one of the editable control and when i click on button, i should tell to user that " data has been modified" .

how can we achieve this scenario?

Note: Think if we have 100 editable controls in a webform.

Since you clearly state that this is an ASP.NET question, try posting it to that forum.

That's a lot of controls. Are you sure you need that many?

Hi Thaer,
Try to use this.

using Microsoft.SqlServer.Management.Smo;

private static Server srvSql;

<code>
     // Create a new backup operation
     Backup bkpDatabase = new Backup();
    // Set the backup type to a database backup
    bkpDatabase.Action = BackupActionType.Database;
   // Set the database that we want to perform a backup on
      bkpDatabase.Database = "Your Selected Database"
    // Set the backup device to a file
   BackupDeviceItem bkpDevice = new BackupDeviceItem(BackupFileName.bak, DeviceType.File);
     // Add the backup device to the backup
             bkpDatabase.Devices.Add(bkpDevice);
     // Perform the backup
       bkpDatabase.SqlBackup(srvSql);
</code>

Let me know if you have any problem !!!
