Pleaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaas Help.....

I thought over anothor approach.

At first I load RVF From database to stream and then I load this stream into

RichView. after that I edit documents and then insert RVF to stream and post

it to table. but my problem dosent solve.

here is my code:

var

IsEmpty: boolean;

Stream: TMemoryStream;

begin

with RVStyle.TextStyles do

begin

Add;

Items[Count].Jump := True;

Items[Count].FontName := 'Badr';

Items[Count].Size := 14;

Items[Count].Color := clBlue;

Items[Count].HoverColor := clRed;

Items[Count].BackColor := clNone;

end;

Stream := TMemoryStream.Create;

DM.Matn.First;

while not DM.Matn.Eof do

begin

Stream.Clear;

DM.MatnMatn.SaveToStream(Stream);

Stream.Position := 0;

RVE.LoadRVFFromStream(Stream);

RVE.Format;

if DM.Matn.RecNo > 10 then exit;

IsEmpty:= (rve.ItemCount=0) or ((rve.ItemCount=1) and (rve.GetItemStyle(0)>=0)

and (rve.GetItemText(0)=''));

if IsEmpty then begin DM.Matn.Next; continue; end;

DM.tblEstelah.First;

while not DM.tblEstelah.Eof do

begin

RVE.SetSelectionBounds(0, 0, 0, 0);

while RVE.SearchText(Trim(DM.tblEstelah.FieldByName('Estelah').Text),

[rvseoDown, rvseoWholeWord]) do

RVE.ApplyTextStyle(RVStyle.TextStyles.Count);

DM.tblEstelah.Next;

end;

Label1.Caption:=IntToStr(DM.Matn.RecNo);

Label1.Update;

Stream.Clear;

RVE.SaveRVFToStream(Stream, False);

Stream.Position := 0;

DM.Matn.Edit;

DM.MatnMatn.LoadFromStream(Stream);

DM.Matn.Post;

DM.Matn.Next;

Stream.Clear;

end;

ShowMessage('Complete');
