How to access external objects ?

robertonicchi

I read in FR3 features:

Access to any object inside your application (in case you've allowed this). Standard libraries to access to base classes, controls and forms. Easily expandable library architecture.

I suppose that this means that inside a Fr3 script i can refere to objects and variables defined out of FR3


but how i can do this ?
If i try to refere to an external object in my form the script stop with an error: undeclared identifier

thank you

The key phrase is "in case you've allowed this".
You can access to any object in your project, but you should add it (using FastScript interface) beforehand. You may add an object to the TfrxReport.Script or fsGlobalUnit. See FS documentation for details.

GREAT !!!

i see that if i do:

frxreport1.script.AddForm(self);

before the report is created i can refere to all the components in the form at runtime



I don't have problems with standard components like the form, a Tbutton or Tlabel
but when i try to use a third party component (NexusDb) i have an error.

what i do is:

frxreport1.script.AddForm(self);
frxreport1.script.addclass(TnxTable,'TnxTable');
frxreport1.script.addclass(TnxDatabase,'TnxDatabase');
frxreport1.ShowReport(true);


in the FR script i do:

form1.nxtable1.tablename:='mytable';
form1.nxtable1.database:=form1.nxdatabase1;
form1.nxtable1.open;

when the script is executed at runtime i have the error:

Script error at 4.45: 'Class TnxDatabase', 'Class TnxDatabase'

Anyway i'll check the FastScript manual/demo that i see is available for download

thank you !!!!

P.S. I like this new toy

robertonicchi

it seems that in the script only the line

form1.nxtable1.database:=form1.nxdatabase1

doesn't works

other methods/property can be used

ex:

nxtable1.tablename:='articoli';
// nxtable1.database:=nxdatabase1;
nxtable1.open;

jflabel1.value:=nxtable1.fieldbyname(description).asstring;

where jflabel1 is a TjfLabel from JfCOntrols components suite

You should add nexus db components by fsGlobalUnit.AddClass method.
