  See a Programmer's manual:

  1.12 Creating a report form from code
  As a rule, you will create most reports using the designer. Nevertheless, in some
  cases (for example, when the report???s form is unknown) it is necessary to create a report
  manually, from code.
  To create a report manually, one should perform the following steps in order:
  - clear the report component
  - add data sources
  - add the "Data" page
  - add report???s page
  - add bands on a page
  - set bands??? properties, and then connect them to the data
  - add objects on each band
  - set objects??? properties, and then connect them to the data
  Let us examine creation of a simple report of the ?«list?» type. Assume that we have
  the following components: frxReport1: TfrxReport and frxDBDataSet1: TfrxDBDataSet
  (the last one is connected to data from the DBDEMOS, the ?«Customer.db?» table). Our
  report will contain one page with the ?«Report Title?» and ?«Master Data?» bands. On the
  ?«Report Title?» band there will be an object with the "Hello FastReport!" text, and the
  ?«Master Data?» one will contain an object with a link to the "CustNo" field.
  Pascal:
  var
  DataPage: TfrxDataPage;
  Page: TfrxReportPage;
  Band: TfrxBand;
  DataBand: TfrxMasterData;
  Memo: TfrxMemoView;
  { clear a report }
  frxReport1.Clear;
  { add a dataset to the list of ones accessible for a report }
  frxReport1.DataSets.Add(frxDBDataSet1);
  { add the "Data" page }
  DataPage := TfrxDataPage.Create(frxReport1);
  { add a page }
  Page := TfrxReportPage.Create(frxReport1);
  { create a unique name }
  Page.CreateUniqueName;
  { set sizes of fields, paper and orientation by default }
  Page.SetDefaults;
  { modify paper???s orientation }
  Page.Orientation := poLandscape;
  { add a report title band}
  Band := TfrxReportTitle.Create(Page);
  Band.CreateUniqueName;
  { it is sufficient to set the ?«Top?» coordinate and height for a band }
  { both coordinates are in pixels }
  Band.Top := 0;
  Band.Height := 20;
  { add an object to the report title band }
  Memo := TfrxMemoView.Create(Band);
  Memo.CreateUniqueName;
  Memo.Text := 'Hello FastReport!';
  Memo.Height := 20;
  { this object will be stretched according to band???s width }
  Memo.Align := baWidth;
  { add the masterdata band }
  DataBand := TfrxMasterData.Create(Page);
  DataBand.CreateUniqueName;
  DataBand.DataSet := frxDBDataSet1;
  { the Top coordinate should be greater than the previously added band???s top + height}
  DataBand.Top := 100;
  DataBand.Height := 20;
  { add an object on master data }
  Memo := TfrxMemoView.Create(DataBand);
  Memo.CreateUniqueName;
  { connect to data }
  Memo.DataSet := frxDBDataSet1;
  Memo.DataField := 'CustNo';
  Memo.SetBounds(0, 0, 100, 20);
  { adjust the text to the right object???s margin }
  Memo.HAlign := haRight;
  { show the report }
  frxReport1.ShowReport;

  thanks for the suggestion but I'm still not clear, so the need for example in delphi. i am tried 2x and both failed, one of for the code below :
  
  code 1:
  
  procedure TForm1.SettingMemoClick(Sender: TObject);
  var Memo: TfrxMemoView;
  begin
  Memo.CreateUniqueName;
  Memo.Text := 'Hello FastReport!';
  Memo.Height := 20;
  Memo.Align := baWidth;
  Memo.SetBounds(StrToInt(EditTopMargin.text), 0, 100, 20);
  frxReport1.ShowReport;
  
  end;
  
  or code 2:
  
  procedure TForm1.SettingMemoClick(Sender: TObject);
  var Memo: TfrxMemoView;
  begin
  Memo:= StrToInt(EditCOL_PAGE.text);//for Column page
  Memo:= StrToInt(EditRow_PAGE.text);//for maximum limit of rows
  Memo:= StrToInt(EditTopMemo.text);//for Top Memo
  Memo:= StrToInt(EditLeftMemo.text);//for Left Memo
  Memo:= StrToInt(EditWIDTH.text);//for width memo
  Memo:= StrToInt(EditHEIGHT.text);//for height memo
  Memo:= StrToInt(EditLine_Spacing.text);//for line spacing memo
  frxReport1.ShowReport;
  
  end;

  in each of your procedures you need to have a report component reference.
  or if you are trying to add to an existing report you must have loaded the report into a tfrxreport component and then use findobject to get the object to which the new memoview will be added.

  Use for example
  TfrxMemoView(frxReport1.FindObject('Memo1')).Left := 100;

  if i want to set the Line Spacing to what the same for memo :
  TfrxMemoView (frxReport1.FindObject ('Memo1')). LineSpacing: = 100;

  Yes. Why you can't to try your code?
