I'm bit frustrated because my app is giving me problems.... It compiles without any errors.
I have a function to get text from a field and another function to save the text to a database. But when I call the "InsertRecord()" function, the simulator craches (I also try the code in PDA, with same results.. ). I can't guess what's the problem.... can anyone help?
Thanks a lot!
