Dear Support

I am testing Fast Report 3.15 and Delphi 7 and I am working with standardization of the screens through inheritance and when trying to do this with Fr he/she gave it is error message in the form son to access Edit Report: CANNOT RENAME COMPONENT FRXREPORT1, COMPONENT WAS INTRODUCED AN ANCESTOR FORM

Hello

I have the same problem. I did a probe with inherited cmponent too, but after I create some controls in the report component (bands and labels in some fashion I need) I can`t assign the names to these controls. I don`t receive errors when compiling or installing the inherited component, but when I invoke the designer I receive a message about "already exists a object with this name o somethnig like this" .

This is my "code".

...

TMyRep = class(TfrxReport)
private
{ Private declarations }
public
{ Public declarations }
constructor Create(aOwner: TComponent); override;
published
end;


implementation

constructor TMyRep.Create(aOwner: TComponent);
var
//_DM : TDataModule;
//_Cfg : TADODataSet;
Page: TfrxReportPage;
BandaEnc, BandaPie: TfrxBand;
DataBand: TfrxMasterData;
MemoComp1: TfrxMemoView;
Begin
inherited Create(aOwner);
{ add a page }
Page := TfrxReportPage.Create(Self);
{ create a unique name }
Page.CreateUniqueName;
//Page.Name := 'Pag1'; // .CreateUniqueName;
{ set sizes of fields, paper and orientation by default }
Page.SetDefaults;
{ modify paper???s orientation }
Page.Orientation := poPortrait;
{ add a report title band}
BandaEnc := TfrxPageHeader.Create(Page);
//BandaEnc.CreateUniqueName;
{ it is sufficient to set the ?«Top?» coordinate and height for a band }
{ both coordinates are in pixels }
BandaEnc.Top := 0;
BandaEnc.Height := 115;
{ Objeto Competencia }
MemoComp1 := TfrxMemoView.Create(BandaEnc);
//MemoComp1.CreateUniqueName;// 'TitCompetencia';
MemoComp1.Text := 'Competencia';
MemoComp1.Top := 0; MemoComp1.Font.Size := 12;
MemoComp1.Height := 20;
MemoComp1.Align := baWidth;
MemoComp1.HAlign := haCenter;
MemoComp1.Frame.Typ := [ftLeft, ftTop, ftRight];

Hello

I think I forgot something. Now I repeated the mentioned process and I could remember.

I could assign names to reports`s bands, labels, etc and the designer showed all right, I could do preview (in design mode), but I can not compile. I receive the error:

Exception Exception in module .... at ......
prDupl


What is this? Help, please.

Thanks in advancve

frxReport CAN NOT be inherited !
