hi,
i tried the changes suggested. but the problem persists. i am giving
the codes of inputall_gui.c and inputall.c below. i would like to know
if any changes are to be made.
also in fdesign in the attributes menu when any thing is added to the
object name or callback fields i get messages like.
Invalid C Identifier Specified for Object Name
float_input
i had to manually add the object names in the inputall_gui.fd file to
affect the changes. what do you think is the problem?
thanks in advance
gopi
