Yes, that user is log on server.
also he has sysadmin rights on db server.
some time he is able to execute his query using ssms.
but some time in middle of query execution he is getting above error.

hi this is also giving error

Excel.Worksheet activeSheet = ((Excel.Worksheet)(Microsoft.Office.Interop.Excel.Application.ActiveSheet));

an object reference is required for the non static field method or property '_application.activesheet'

suppose I have put it on following path
then in following code what should be placed instead of "Product.xml"
xmlFile = XmlReader.Create("Product.xml", new XmlReaderSettings());

when I have Used as
using (XmlReader reader = XmlReader.Create(@"D:\VSTO_Vinayak\Product.xml"))

it is giving exception as {"Could not find file 'D:\\VSTO_Vinayak\\Product.xml'.":"D:\\VSTO_Vinayak\\Product.xml"}

Its working but when I am assign list values to string variables if null then throwing exception

MSubject = iteam.Subject.ToString(); // if null throwing exception

if I put it into in if block to handle null
MSubject = iteam.Subject.ToString();

then MSubject variable is not accessible outside
so how can handle this

public Email FetchEmail(int emailId)
if (IsResponseOk(SendCommand("TOP " + emailId + " 0")))
return new Email(ReadLines());
return null;

protected string ReadLines()
StringBuilder b = new StringBuilder();
while (true)
string temp = ReadLine();
if (temp == ".\r\n" || temp.IndexOf("-ERR") != -1)
return b.ToString();

I want Mail Body in Insert Method() but it is giving only following

ContentType = iteam.ContentType.ToString();
From = iteam.From.ToString();
Headers = iteam.Headers.ToString();
Subject = iteam.Subject.ToString();
To = iteam.To.ToString();
MailDate = iteam.UtcDateTime;

Here I want Mail Body Also

[index].Value here Value showing Error i.e Red Line

Code now is

//foreach (DataColumn column in HeaderColumns.Columns)
// string columnName = HeaderColumns.Rows[0][column.ColumnName].ToString();
for (int index = 0; ; ++index)
string columnName = HeaderColumns.Rows[0][index].Value.ToString();
if (string.IsNullOrEmpty(columnName))
// etc

Showing Error Object does not contain a definition for 'Value' accepting first argument of type object could not be found (are you missing) a using directive or an assembly reference
