Comment on Datawindow Buffers by Ivaylo Ivanov

One little addition to your description for the Original buffer:

You can indirectly modify the values in this buffer by performing SetItem for the column and then SetItemStatus to NotModified! which transfers Primary! buffer value into the Original one.

Note that such change would reflect the contents of the Where clauses of the issued SQL Update/Delete statements!

Usually such behaviour can be experienced when trying to issue DeleteRow() for a newly inserted row with status of New! or NewModified! – they’re are not supposed to be moved into the Delete! buffer, because they shouldn’t issue any SQL statement on the next Update().

Check if this is your case. Use GetItemStatus() with colindex=0 to obtain the status of an entire DW row.

Great site! Thanks for the hints!

Comment on Working with DDDW Properties by Gord Cross

Hello,

Thanks for the site. It has alot of helpful info.

This is sort-of related, I am trying to modify a graph that is on a composite datawindow. Is there any way to do this?

I’ve tried to get the datawindow containing the graph using getchild(). This gives me a DataWindowChild upon which I can only execute Modify() commands as it does not support going after the graph (gr_1) directly, nor does it support SetSeriesStyle(). Unfortunately, something as easy as setting the series color is not possible (at least I couldn’t figure out how) in either the painter or using a Modify() command.

Do you have any ideas?

Thanks in advance.

Thanks for the code.

One minor point…
Use Longs instead of integers for insert row numbers and file counts as the PB max for integer (32767) can easily be exceeded.
