Does anyone have any code that will allow me to search in a DBMemo field.

Thanks

The following deals with TMemo, but it should work also with TDBMemo:

Place a TMemo on a form and try this one, it's case sensitive:

procedure TForm1.Button1Click(Sender: TObject);
var FText: string;
size: integer;
Buffer, FindBuf: PChar;
A: array[0..255] of char;
begin
if InputQuery('Find Text', 'Enter text to find:', FText) then
  with memo1 do begin
    setfocus;
    size:=gettextlen+1;
    GetMem(Buffer,Size);
    GetTextBuf(Buffer,Size);
    FindBuf:=StrPos(Buffer,strPCopy(A,FText));
    if FindBuf<>nil then
    begin
      selstart:=Size-StrLen(FindBuf)-1;
      sellength:=length(FText);
    end
    else
      showmessage('not found');
    FreeMem(Buffer,Size);
  end;
end;

to make the search in case not sensitive write:                             FindBuf:=StrPos(strupper(Buffer),strupper(strPCopy(A,FText)));
instead of
  FindBuf:=StrPos(Buffer,strPCopy(A,FText));

Thanks ronit for the above solution, what I need to also do is to implement a find again option, i.e. I might have two or more occurences of the same word I am looking for in the dbmemo, and I need the user to be able to search again in the same memo, any code would be appreciated
To do find next expand this basic procedure for your own needs, say run this procedure a number of times as the number of words you need to find, so that each time you load to a buffer the rest of the text, needed to be searched (that is from cursor position to the end of the memo).
