Title: Search text in your MEMO
Question: How can i search text in a Memo like MS Word?
Answer:
In many of my applications I must to work with MEMOS and accomplish search of text with the following procedure:
1. Put a Memo, this too is valid for a DBMEMO component.
2. Put a FindDialog component.
3. In the event OnFind of the component FindDialog put the following code:
procedure TForm1.FindDialog1Find(Sender: TObject);
var Buffer, Pos, tPointer : PChar;
BuffLength : Word;
begin
With Sender as TFindDialog do
begin
GetMem(tPointer, Length(FindText) + 1);
StrPCopy(tPointer, FindText);
BuffLength:= Memo1.GetTextLen + 1;
GetMem(Buffer,BuffLength);
Memo1.GetTextBuf(Buffer,BuffLength);
Pos:= Buffer + Memo1.SelStart + Memo1.SelLength;
Pos:= StrPos(Pos, tPointer);
if Pos = NIL then MessageBeep(0)
else
begin
Memo1.SelStart:= Pos - Buffer;
Memo1.SelLength:= Length(FindText);
end;
FreeMem(tPointer, Length(FindText) + 1);
FreeMem(Buffer,BuffLength);
Memo1.SetFocus; //This line highlight the found text
end;
end;
4. Call to the FindDialog1.Execute and see the results.
I hope this serve to you
