What have we learned so far? • • • •

Saving Projects properly Placing Controls on the Form Changing the Name Property of a Control Setting other properties of a Control

Form at Run Time

What makes a program work?

Accessing the Code Window • Clicking on the View Code button Project Explorer Window • Selecting a Control and Pressing F7 • Double-Clicking on a Control

on the

Parts of the Code Window

Object List Box • Lists the objects or controls in the form

Event List Box • Lists all events or procedures related to the selected control

Terms to Remember • Controls – also called objects • Procedure – events; declarations that are performed when you do an action to an object • Private – indicates that the procedure will only take place inside the form • Sub – stands for subprocedure • Private Sub – start of a subprocedure • End Sub – end of a sub procedure

Sample Code Private Sub cmdYes_Click () lblText.Caption = “Welcome!!!”

End Sub

Good Programming Practices To improve the readability of your code: • Indent the lines between the Private Sub and End Sub • Places spaces between lines

Good Programming Practices To be more accurate in creating subprocedures • Double-click the control (this automatically types the Private Sub and End Sub) • When typing the Property, choose from the list box that comes out after typing the first letters then press Space
