I have a paradox table with a memo.  I need to find records containing a certain text in the memo.
I'm using a OnFilterRecord to do that.

Procedure TDataModule1.Table1FilterRecord(DataSet: TDataSet; var Accept: Boolean);
Begin
 Accept := Pos('Hello world', Table1.Memo.Text) ;
End ;

But it do not work.  I have an error message telling the memo can not be access in a filter.
How can I do that ???

Thank you.

Try this. It assumes that you have a field called memo in Table1.

Begin
  Accept := Pos('Hello world', Table1.FieldByName('Memo').AsString) > 0 ;
End ;

if  nnbbb09 comment not work, then it could be impossible,
except you don't have replaced 'Memo' with your real fieldname

but, maybe this helps, (just modified nnbbb09 comment, not tested)
Begin
  Accept := Pos('Hello world', TBlobField(Table1.FieldByName('Memo')).AsString) > 0 ;
End ;

I just tested  nnbbb09 comment and it works fine.
Created a form a table a source a grid and a button.
The grid displays the COMPONENTTYPE Field of the table.
When you turn on the filter only the Records in the
table that have 'COMPUTER' in them show.

*******************************************************
procedure TForm1.Table1FilterRecord(DataSet: TDataSet;
  var Accept: Boolean);
begin
  Accept := Pos('COMPUTER', Table1COMPONENTTYPE.Value) > 0;
end;
******************************************************
procedure TForm1.Button1Click(Sender: TObject);
begin
  Table1.Open;
  Table1.Filtered := True;
  Table1.Refresh;
end;

No comment has been added lately, so it's time to clean up this TA.
I will leave a recommendation in the Cleanup topic area that this question is:

Accept nnbbb09's comment as answer

Please leave any comments here within the next seven days.
 
PLEASE DO NOT ACCEPT THIS COMMENT AS AN ANSWER!
