"...The best solution is to use a class instead of a code module. You can then initialize the class in each of the activities. It will allow you to share more features between the activities..."
These are the word of Erel
The question is: how write a class to obtain a messagebox usable from code/service module?
For example, an app with 3 form and 1 module
When app start form1 is displayed, then operator press and go on form2, on module1 an sms is received and the code on module1 need to visualize a message
How write a class to display the messagebox and how instantiate it in form1, form2, form3?
