[RESOLVED] Excel & reading cells content

[Saeed]

I have functions that use
OleDbCommand , OleDbDataReader and OleDbCommand
to read values of cells within an excel sheet.

it works fine for everything else , however in some cases like:
Row 12-15 ,Column Z , it returns null and i have no idea why
What is about these cells that is giving me the grief ..

Cheers

            OleDbCommand query = new OleDbCommand(strSql, connection);
            reader = query.ExecuteReader();
// blaa blaa
            while (reader.Read())
            {
                foreach(string column in columns)
                {
                    iColumn++;
                    string x = null;
                    try
                    {
                        x = reader[column].ToString();
