Have a label box to display the QPA and command buttons to calculate the QPA and to exit the program. Set the tab index values for the two arrays in order to make it easy to tab through the boxes and enter data. Test your program and save the project on your disk. Print both the form and the code for your instructor. In this lab, you specified that a set of textboxes was to be treated as what Visual Basic terms a control array.
Arrays are common to many programming languages.
This is an efficient way to handle similar sets of data. When the same sets of data are required for more than one program, a business will design and set up a database. In the next lab, you will set up a Visual Basic interface for a database.
