Invocations between objects
When an object invokes another object, how is information passed? For instance, an object that requires the user to enter a country and calls a listing to print the attractions in that country.
Version: GeneXus 17
GeneXus Core course
A web panel is used to request data from the user. A variable is used in it as dynamic combo box, that is: a variable that loads all countries for the user to make his selection. We study the parm rule to declare the parameters that an object receives. We use “in” to indicate that a parameter is input. Only the case where the parameters declared in parm rule are variables is studied here.

Presentation
Objective:
Through the development of an application, we will teach you the basics of GeneXus that will allow you to understand its logic and quickly build any type of application, now or in the future.
Prerequisites:
Basic programming and database skills. If you do not have them, we recommend that you study this material prior to the start of the course.
Suggested methodology for this course:
Alternate the theory with practice exercises you can download from the “Materials” section.
Watch every video and in parallel do the practice exercises corresponding to those topics, until you have completed all the videos of the course.
Approximate duration:
Theory/Practice: 45 hours (not including the optional "bonus videos" that appear at the end of the course)
If you purchase the course, you will work on it within a study platform (LMS) and you will also have:
Exam:
It is a computer-based exam, with multiple choice and true/false questions and exercises.
When you pass the exam, you will receive an internationally valid “GeneXus Junior Analyst” certification and will be included in the list of GeneXus-Certified Technicians.
Here you can see the Exam Calendar.
