New Post: Does ClosedXML instantiate a new instance of Excel?

I already did that and there is no error. It works OK on my laptop (but then again, I have Excel – thus the reason why I thought it was req’d). I attached the snippet of code that does this. I have plenty of logging in it to trap any errors. None found.

var workbook =newXLWorkbook();

wsname = wsname + PayDate.ToString("MMDDYYYY");

fn = sFilePath + sNomenclature +".xlsx";

var worksheet = workbook.Worksheets.Add(wsname);

sql ="SELECT EmployeeID, PayDate, CostCenter4, CostCenter5, Costcenter6, Qty, PieceWork "+

"FROM WRFXUpld "+

"WHERE cast(PayDate as smalldatetime) >= cast(@PayDate as smalldatetime) "+

"ORDER BY EmployeeID, PayDate, CostCenter6, CostCenter5 ";

SqlConnection mySQLConnection =newSqlConnection(sConnectionString);

mySQLConnection.Open();

SqlCommand mySQLCommand =newSqlCommand(sql, mySQLConnection);

mySQLCommand.Parameters.Add("@PayDate",SqlDbType.Char);

mySQLCommand.Parameters["@PayDate"].Value = cPayDate;

try

{

string s15 ="Attempting to SELECT fields from WRFXUpld for the spreadsheet...";

Log(s15);

SqlDataReader mySQLReader = mySQLCommand.ExecuteReader();

string s16 ="Finished SELECT fields for the spreadsheet...";

Log(s16);

if (mySQLReader.Read())

{

string indcell ="";

int i = 1;

string s17 ="Going into loop to populate spreadsheet...";

Log(s17);

while (mySQLReader.Read())

{

indcell ="A"+ i.ToString();

worksheet.Cell(indcell).Value = mySQLReader["EmployeeID"].ToString().ToUpper().Trim();

string s17a ="In the spreadsheet loop for EmployeeID = "+ mySQLReader["EmployeeID"].ToString().ToUpper().Trim();

Log(s17a);

indcell ="B"+ i.ToString();

worksheet.Cell(indcell).Value = mySQLReader["PayDate"].ToString().ToUpper().Trim();

indcell ="C"+ i.ToString();

worksheet.Cell(indcell).Value = mySQLReader["CostCenter4"].ToString().ToUpper().Trim();

indcell ="D"+ i.ToString();

worksheet.Cell(indcell).Value = mySQLReader["CostCenter5"].ToString().ToUpper().Trim();

indcell ="E"+ i.ToString();

worksheet.Cell(indcell).Value = mySQLReader["CostCenter6"].ToString().ToUpper().Trim();

indcell ="F"+ i.ToString();

worksheet.Cell(indcell).Value = mySQLReader["Qty"];

indcell ="G"+ i.ToString();

worksheet.Cell(indcell).Value = mySQLReader["PieceWork"];

i = i + 1;

}

string s18 ="Finished looping to populate spreadsheet...";

Log(s18);

mySQLReader.Close();

mySQLReader.Dispose();

workbook.SaveAs(fn);

string s19 ="SAVED the spreadsheet!!!";

Log(s19);

}

else

{

string s20 ="No spreadsheet to save due to no data.";

Log(s20);

}

mySQLConnection.Close();

mySQLConnection.Dispose();

}

catch (Exception e4)

{

mySQLConnection.Close();

mySQLConnection.Dispose();

string s ="Unable to create spreadsheet due to: "+ e4.Message;

Log(s);

}

}

Thanks!
