The problem, The INSERT statement works fine in the form load but not in the button click event?
User need to select their prefferable data to show in report. What i did is i have a clear command first to delete the temporary table. The temporary table is basically a table to stored user selection parameter data. After the clear command, i have
a insert command to insert user selection data into the temporary table. What happened now is when i run the program exe, first run of the report is work fined, but not the second and the following times of execution. It will return null or blank report. The weird thing is when i execute it from development environment, it seem like the report is able to pick up user selection parameter and run the report for the first times and the subsequent execution.
I'm trying to create this select command against Access Database----Keeps giving me error saying operator is missing I just can't seem to figure it out

I've been using SQL OleDB commands to grab data from some excel files and it's working well, but I'm having a really hard time finding a good resource for the actual command strings on the web. I figure I must not be using the proper terminology in my searches. Take this line:
Dim da as New OleDb.OleDbDataAdapter("Select * From [" & sheetName & "]", Conn)
My question this morning was: Can I pass a command that will grab all sheets from the excel document instead of just one in particular?
In my .NET application I have to get results from a MS Access database. I would like to add error checking to make sure a row was returned from my SELECT statement.

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....
