IWorkbook workbook = application.Workbooks.Create(1);
IWorksheet worksheet = workbook.Worksheets[0];
// Database path
string dataPath = Path.GetFullPath(@"c:\company\DB\TestDB.mdb");
// Connection string for DataSource
string ConnectionString = "OLEDB;Provider=Microsoft.JET.OLEDB.4.0;Password=\"\";User ID=Admin;Data Source=" + dataPath;
// Adding a connection to the workbook
IConnection Connection = workbook.Connections.Add("Connection1", "Sample connection with MsAccess", ConnectionString, "", ExcelCommandType.Sql);
// Adding a QueryTable to sheet object
