Using a message box to make a choice

It is possible to use a MsgBox to make a choice in your program. You first of all assign a integer variable to the MsgBox then you change the buttons attributes to vbYesNo. vbYesNo is a VB constant that represents a value, the use of the constant means that you do not need to memories the number, vbYes and vbNo are other examples of these VB constants. An IF statement is then used to make the selection.
