FR 3.16 Update Problem

ShaneStump

I just finally updated to 3.16 (I believe the last version I was using was 3.12 or so).

Any how, I add variables to my TfrxReport object as such in my C++ code:

Report->Script->Variables["bShowMasterNotes"] = true;


From within the Fast Report fr3 file, I access it as such:

procedure MasterNotesChildBandOnBeforePrint(Sender: TfrxComponent);
begin
with MasterNotesChildBand, Engine do
begin
Visible := ((<AccessoryMasterTable_."Notes"> <> '') AND (<bShowMasterNotes> = True));
end
end;


~~

The <bShowMasterNotes> reference in the script causes an Invalid Variant Operation.

How do I fix this?

Regards,

Shane

Anybody from FR home?

Two of my applications are now BROKEN again because of the recent upgrade.

Is there any way to get a copy of version 3.12 again since there seems to be no support for version 3.16?

I am getting a lot of complaints from customers.

If no one can recommend a fix for Fast-Report, can anyone recommend a report writer that works with C Builder that comes with support?

Hi Shane,

the problem seems to be a incompatibility within fr316 because they changed the <> Variable - Tags to old [] behavoir (fr25). So you have to change all your scripts
from

<MyVar>:=<MyVar>+1;
to
[MyVar]:=[MyVar]+1;


I also went back to a earlier version because its immpossible for our team to change all customer - reports. I hope fr will fix this in the next release but got no awnser till now.

Thanks.

I was able to get a copy of my backup of version 3.12 from our server and I have reinstalled it for now (my primary business is in New Orleans so I am very busy now and don't have time either to fix several hundred reports).

Best Regards,

This bug fixed in FastReport 3.17 (today release).

Michael,

Thanks - I am downloading FR 3.17 from my car now as my partner and I drive to New Orleans to check out our office.

I will try it later tonight / tomorrow with my hobby program Drivers Log.

Best Regards,

And answer from Alexander Tzyganenko for all such cases:
---
you should use [] or <> (what you want - both are equals) for:
- dataset/field: <ds1."fld1"> or [ds1."fld1"]
- system variables: <Page> or [Page]
- variables supplied by TfrxReport.OnGetValue event: <myVar> or [myVar]
- report variables defined in the Report|Variables menu, or passed by
TfrxReport.Variables := ... : <myReportVar> or [myReportVar]

all other things such as script variables (defined in a script, or passed by
TfrxReport.Script.Variables := ..), functions, methods, objects -
should be acessed without [] or <>.
