OVERVIEW:I am currently having an issue loading a large number of rows into Excel. I say large because the attached code in fact correctly inserts 50 rows into an Excel worksheet, however, as the number of rows increases to no more than500 rows the data is not inserted into the worksheet. No error is thrown by .net and the .xls filesize actually shows an increase in size, however, when the file is opened there are no rows in the spreadsheet..... Then, when the .xls file is closed the filesize is once again reduced.
Again, the code works for a small number of rows. Are there any known bugs with the OleDB driver for Excel?ADDITIONAL THOUGHTS:I have tried inserting rows to both Excel 2003 and 2007, same issue.I have tried closing the connection after each insert.... performance if horrible and it does not fix the problem.I have wrapped the ExecuteNonQuery in a transaction.... no go....
