Jill,
This may seem elementary, but sometimes that's the hardest to see...
1) Did you change "dw_1" to your appropriate target DW control name?
2) Did you code of_SetQuerymode(TRUE) for your target DW control?
3) Before you can "Save" a query, QueryMode must first be enabled (i.e.
your user must be in QueryMode to "Save" a query. So we normally
disable/enable our command button appropriately.
When does your null object reference error occur? Do you ever see the
system Open File dialog window appear (the one that will get the user's
filename selection)? Any other code in the button?
Any other suggestions?
Good luck - Let us know what it is when you figure it out.
Have fun,
~Sharon
