Hello
For a project I have to generate a password with four characters. This characters can be digit from 0 to 9, letters from A to D and composed of two characters “*”, “#”
Thank you for your help
Ok, so what's the problem?
Is this homework?
Welcome Sami.
What you intend to do can be done several ways.
A search of the community regarding password generator. provides links of all the discussions in this community regarding creating a password generator. Perhaps you can adapt one of these to your Project.
A way to do this might be to randomly select from a list containing 0,1,2,3,4,5,6,7,8,9,A,B,C,D,*,# four times, each time adding the selected item to a label to get something like 3#C7 .
Here are some resources to help you learn to use the AI2 tools. A very good way to learn App Inventor is to read the free Inventor's Manual here in the AI2 free online eBook App Inventor 2 Book: Create Your Own Android Apps ... the links are at the bottom of the Web page. The book 'teaches' users how to program with AI2 blocks.
There is a free programming course here Course In A Box and the aia files for the projects in the book are here: App Inventor 2 Book: Create Your Own Android Apps
