Dynamate report creation....help

D

Danka

I have the following code to generate an Access report based on an Acsess
query. It depends on the number of columns (up to max. 31 that is the max
number of column headers I can assign to the letter size paper in landscape
mode) in the query and it will construct the report for it. For wharever
reason the report takes very long to generate and tahe forever to send to
the printer...last time I waited for over 1.5 hour befoer I killed the
proceess. Please can anyone point me out what is wrong with my coding. It
seems to me the "Detail1_Format" is the source of the delay/problem. For a
small recordset (20 rows and 25 columns) I managed to open the report and
send it to the printer in about 5 minutes.....however it took very long last
time with 26 columns and 200 rows in the recordset before I killed the print
job. Thanks.

"up to max. 31"... are these for days of the month? Is there a reason why you
are using a solution like this? There are possibly more efficient crosstab
reports.

Can you describe your crosstab query and data?

I'm not sure about your original table structure but there are some sample
crosstab reports at
