Hi

is there any easy way to check if a field is empty.
I need the equivalent <table.empty> for screen controls

thanks

Hi,

empty edit controls for strings are detected easily by IF Nospace(MyEditControl) = "" THEN ...

For many controls, in the 7-Tabs-Window / Details Tab there is a check box 'Return NULL if empty' this one can be used for identifying an empty control

Kind regards,

Hi Guenter

the 'return null if empty' never crossed my mind.
that work as I can always check for 'null'

thank you
Noel
