Not all controls require a pop-up menu to be created. Certain controls that
ship with Visual Basic, such as the TextBox control, already have a pop-up menu
built into them, as shown in Figure 3.7. Visual Basic has no method to disable
such built-in, pop-up menus.
FIGURE 3.7 - The built-in pop-up menu of
the TextBox control.
If the PopupMenu method is used with a control
that has its own built-in, pop-up menu, the
built-in menu will always be displayed first.
The custom menu will only be displayed subsequently.
Displaying two separate menus is not usually
the desired effect for the user interface.
The benefit of built-in menus is that they do not require program code for
their functionality. The control provides all mouse handling and functions.
