Tech Tip: How to modify the DatabaseName stored
with a DADE Query
-------------------------------------------------
Currently when DADE is used to create dat… -
Here is an example of a report that contains a custom query and two detail
queries on orders. The first orders query contains an autosearch criteria on
SaleDate, the second query contains an a search criteria (but not
autosearch… -
I think the issue here is that it is too late to add autosearch criteria -
the autosearch dialog has already been displayed.
I think you want to define the second search criteria using the Query
Designer and define it as A… -
The report, datapipeline, etc. all need to have the same Owner. The Owner is
typically a Form/DataModule. This enables the all of the object references
to be resolved when the .rtm is loaded. (RB is using standard Delphi

Unfortunately we cannot make the source code to RAP available. The
competition blatantly copies our trade secrets when this occurs. To date no
competitors have anything close to RAP or RB Server. The reason for this is
that they… -
Have not heard of this before. There is nothing in RAP that requires any
special version or capabilities of Windows. I use Windows 2000 on my Tech

Use the Report.OnPrintDialogClose event to set the ModalResult to 2 - this
is equivalent to mrCancel (mrCancel is not currently defined to the RAP
RTTI). I just tested this from RAP and it worked.

I tried a simple example in which I created a report, configured the
NoDataBehaviors and then save the report to an .rtm. I then changed the
TppReport.NoDataBehaviors back to the defaults and wrote a Button OnClick

1. In my testing here the NoDataBehaviors property is working correctly.
Note that this is a published property. Therefore when you load a report
from .rtm or database, the NoDataBehaviors that were saved with the report

Sorry, there is no way to suppress the dialog. The only way it is not shown
is if the report is being loaded into a separate thread (i.e. not the main
thread of the app).
Probably the simplest solution is manually load eac… -
1. I researched this and was able to detect it in the FooterBand.BeforePrint
event. (The DetailBand.AfterPrint is too early).

You can change the names of the DataSources via the Data workspace. Access
the Query Designer and select the SQL tab.
To customize the AutoSearchDialog, see RBuilder\Demos\AutoSearch\Custom

Sorry for not responding sooner. Thanks for pointing that out the flaw.
Looks like the code needs to modified so that the ModifiedNames object is

The FModifiedNames TStringList object is created in the the

First try to implement something using Delphi code and then convert it to
RAP pass-thru functions. My first try would be to traverse the records in
the report.DataPipeline.

Thanks for the feedback.
I'll add this to the list of requested enhancements. Because of the way in
which the Parser is currently handling comments, it is not a trivial change.

I tried a simple example like this

Try clearing all ShiftRelative relationships first and then in a second step
define the new relationships:
{clear shift relative relationships}
myDBMemo1.ShiftRelativeTo := nil;
myDBMemo2.ShiftRelativeTo := nil;
…
That is a mistake.
Thanks for pointing that out, we'll get it fixed for the next release...

Sorry, I do not understand the question. You can specify search criteria
like that via the Data tab by using the Query Designer. Specify the Like
operator. Designate the criteria as AutoSearch if you want a dialog to be

I researched this and currently there is no way to cancel a report that is
invoked from the report explorer. The ClientReport demo is using the

I assume that are using RB Server Edition and creating a ClientReport app
that connects to an RB Server. In a Server environment all of the RAP code
executes on the server, thus you cannot write RAP code that displays any
