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 .
