Rave Param Equivalent in FR

JohnPattison

I am converting from Rave to Fast Reports.
My rave project has a number of parameters which are set programatically from a Delphi form :
eg:
rvProject.SetParam('lblCriteria',rsCriteria);

This sets a parameter in the rave project which I then use in a data text component on the report.
I set the component's DataField property to Param.lblCriteria

What is the equivalent in Fast Reports?

I prefer to use TfrxReport.OnGetValue

I can't find an OnGetValue Event on my report.
I created one like page 33 or the Programmers Manual:

procedure TForm1.frxReport1GetValue(const VarName: String;
var Value: Variant);
begin
if CompareText(VarName, 'My Variable') = 0 then
Value := 'test'
end;

and on the report:
create the report and lay the "Text"
object to it. Type the following text in this object:
[My Variable]


But when I run the report it says error in expression 'My Variable': ';' expected.

You must create the variiable in the categorized variable list

I have not referred to TfrxReport.OnGetValue from the report but from the source.
TForm1.frxReport1GetValue is assigned to TfrxReport.OnGetValue from your source.
I do not create the variable in the report and it works.
But you can not use spaces in variable names.
"MyVariable" is OK, but "My Variable" is not.
