I have a report, that contains a datawindow, which itself contains a
datawindow. Everything is working fine until the number of retrieved lines
get's over about 1100 primary and over about 3200 retrieved nested lines.
Although the task manager (I'm using Powerbuilder 7.0.3 on Windows 2000)
shows me, that there is still enough free memory, the data retrieval stops
and Powerbuilder (or the application which called the Retrieve() method)
ends itself without any error message. That allways happens when the
datawindow has allocated about 70 MB of virtual memory. (About 99% of those

...nested datawindow within another nested datawindow?
I was trying to create a report which has a nested datawindow within another
nested datawindow, and PB didn't seem to go for this... got memory errors.
Is this even possible? I searched all of the usual resources and couldn't
find anything about this... maybe they assumed nobody would be dumb enough
It is perfectly legal to have multiple levels of nested reports. However,
nesting isn't supported for certain DW types like grid and n-up. Try testing
your DWs on their own to ensure that they work properly. Then nest them one
at a time and try to i...Child datawindows (Nested DataWindows)
Hello all...I was wondering... I have used Child Datawindows
for quite some time under PB9.03. These are invaluable when
a user is in the Parent DataWindow and must choose a value
from a list of choices provided by the Child DataWindow. The
kind of Child DataWindow I am talking about is a
DropDownDataWindow (DDDW). This is the only kind I have ever
used. I was simply wondering whether there are more kinds of
Child DataWindows other than the DDDW? Any info would be
The next most popular use is of child DWs within
Composite Presentation Style parents.

How Can I access/modify object/control from a Datawindow within Datawindow.
When i access/modify object/control from a Datawindow i used
dw_1.modify("name.text = 'new val'") but within another datawindow or child
datawindow it doesnt work.
Your description is difficult to understand due to the terminology. First,
a datawindow is assigned to a control - either a datawindow control or a
datastore. Second, the Modify function can only be called within a script.
With that as a basis, can you rephrase the question and describe more
precisely what you want to do? ...DataWindows and datawindow objects
Difference between Datawindow and datawindowobjects?
- datawindow is a control on a userobject or a window
- datawindowobject (DWObject) is a control within a datawindow, defined in
the dataobject of the datawindow.
You refer to it as <datawindow-instance>.Object.<datawindow object>

Add direct setting and getting capability for the datawindow where clause.
This would have to be a string array in case of unions.
Return ONLY the where clause(s) in the main select (in case of sub-selects,
ignore the where clause or somehow list it as a subselect in the where or a
subselect in the select).
It would be great if I could just get and set this as a value and have the
datawindow automatically change (or add) the where clause as specified.
This is for setting the where clause dynamically at run time. Currently
have to parse through the datawindow.table.select looking f...Datawindows with child datawindows
I want to create a datawindow whose only data is three columns that will
themselves be drop-down data windows. These child datawindows will be
populated in PB script with dw_1.GetChild(). When I create that parent
datawindow (New | Datawindow | Freeform), what do I choose in the next
dialog box ("Which datasource would you like to use?") External?
That depends on how you want to populate and use the columns of the main DW.
The DDDW is an edit style that assists the user in selecting a value for the
column in the main DW. If you want to retrieve the values ...datawindows in composite datawindow used in datawindow.NET, are not sliding up
