Accessing main report TppParameterList

rbuser

Hi,

I have a Master with several parameters (Factor2, Factor3, UnitPerCrate). I
have a child report that NEED to access these parameters. I tried the
following statement :

ContTemp := TotalCont -
(int(TotalCont / TppReport(Report.MainReport).Parameters['Factor2']) *
TppReport(Report.MainReport).Parameters['Factor2']);
Value := ContTemp;

It causes an Access Violation. I comment the ContTemp assignment and the AV
goes away (but my value is still incorrect). How can I access the MainReport
parameters ?

Report.MainReport should return a reference to the main TppReport object.

1. Delphi code

When using Delphi code, the syntax

Report.Parameters['ParamName']

returns a reference to the TppParameter object. Then you need to use the
TppParameter.Value property to access the value. Example:

var
lParameter: TppParameter;
begin

lParameter := ppReport1.Parameters['ppParameter1'];

ShowMessage(lParameter.Value);

end;

2. RAP code

For RAP code we were able return the Value when using the syntax

Report.Parameters['ParamName']

Example:

ShowMessage(TppReport(Report.MainReport).Parameters['ppParameter1']);

3. Nested expressions

When using RAP, sometime nested expressions do not work well. In this case,
use more intermediate local variables
