Can you had the '[' ']' elements to expression filter. Rave reports use this an it says parcing error zexprs... etc. It works with '(MOVID)=19' but not with '[MOVID]=19'. I solved just patching the code on setfilter with stringreplace but is not good. So can you add next verson this. Thanks :idea:

Does any one know a way to use master detail field without posting master ??? I can use the detail field disconnected and put 0 value on the detail field and when i save the master record just change the detail field into detail records. But this is a bit worky. There is other way to do this ? Thanks

Ok this solved tehre is a fb SQL command witch is COMMENT so comment fields

Use the createblobfield function. var aBlob : TBlobField; begin aBlob := TBlobField.Create(Field,Mode); aBlob.Write(); aBlob.Read(); end; But the best is to create a function to read and other to write and the parameter is (aBlob:TBlobField;var Value:string) : Boolean; This could help you a bit. :)

What is EHLIB wher can i find it

It suppose to work with all zeos datasets or all dataset descendent. I dont think copying the data to a local dataset is good idea becaus e i have it on some part of other softwares and it stays a bit slow (im thinking this could work without slowing at least with 3 million rows). Im doing this beca...
