How to determine the form Mode?
I mean How to Know if the form is in Edit mode or insert mode?

it depends on your tool-bar.
when you disable “update” and the “go forward” “go backward” - buttons, your form will automaticly be in insert mode.
when you disable insert-button and enable update, you are in update mode withour navigation and without insert-option.
when you enable navigation, user can navigate.

when you enable all these tools, the user can do both: update data and insert new.

when you want to change behavior, make two forms, one just for updating, one just for insert
i dont know - i never used - if there is a macro for showing/hiding these buttons to change the mode of the form without using a second form.

But I need with code or macro determinete if the form Is in mode Edit or Is in mode Insert, for execute other scripts
