- For RB 10.03, the GlobalOnCreate is fired called from the
Report.InitializeParameters method. This change was made because it was
firing too late (after the autosearch dialog had been displayed). It needs
to fire before any… -

That is a mystery indeed, there must a difference between the two somewhere.

I tried a simple example here. At first I received an AV and after some
trial and error was able to get it to work by adding some code to the
Initialization section to register the TChart class.

- In Delphi code you can reference Crosstab.Matrix.Value[aColumn, aRow].
- For RAP code you will to write a pass thru function.
Run RBuilder\Demos\Crosstabs\Demo.dpr and cehck out ct126.pas, it contains
an example of formatting cell color. I was able to use the same code in RAP.
The example uses the Crosstab.OnFormatCell event and the following code to

please create a simple test case using the DBDemos data and email to

it in the debugger.

Digital Metaphor…- Ok, well like I said in a simple test here it worked. However, your code
example below is much more complex.

{Pms_Project['PMS_PROJECT-Proj Stat Funding'] value is place…

causing the AV

properly in my testing here

Please update to RB 10. RB 10 includes support for Delphi 2006, Delphi 2005,
Delphi 7, and Delphi 6. RB 10 includes many new features and hundreds of
internal improvements and fixes since RB 7. One of these features is Delphi
Try omitting that statement.
When you call TdaSQLBuilder.Free, the destructor will automatically call
ApplyUpdates if it detects that modifications have been made to the TdaSQL.
I researched this and we need to expo…
For RB 10, the internals of the designer were refactored/rewritten. Here is
an example that shows how customize the menus and toolbars.

-…I suspect the eror is elsewhere - you did no post the entire source code the
custom functions. Compare the signature of the functions, perhaps that can
provide an answer. Also, make sure that the datapipeline is not returning a

- like most all of the dialogs in ReportBuilder, the AutoSearch dialog can
be replaced. For an example of a custom autosearch dialog, check out
RBuilder\Demos\AutoSearch\Custom AutoSearch Dialog.

I recommend using RB's AutoSearch feature to implement "ask at runtime"
search criteria. RB will automatically generate the dialog and modify the
SQL Where clause for you.

You need to do it in steps.
SQLBuilder basically works like the QueryDesigner - they are organized like
the tabs of the query designer interface. They both manipulate an underlying

I tested this using RB 10.04 (the latest release and it worked). I tested

I recommend updating to RB 10.04. Over time we have fixed some intermittent
