Hi!

Can you introduce a simple sample scenario to reproduce the behaviour? What DLL you use and how? Also, TextBox is not capable to edit NULL values well. When you edit the date and clear the text box, this produces the empty date value, and asa result the replacing in ODBC by minimum ODBC date value. Are you sure you worked with NULL value? That is what I'm asking.

>Hmm, I really appreciate your help Vlad, but something is not right with these .NULL. and ODBC thing. I forgot to tell you that I use dll as the control source for textboxes... Try this and you'll find it interestingly weird....
