Standard Toolbox Controls
In the previous section, we listed some common properties
that most controls support. In this section, we will
describe the most useful standard toolbox controls.
By taking a brief tour of the controls and their properties,
you'll better understand the purpose for the controls.

Do not try to memorize all the
properties for all the controls. |
The Form
Form objects are the basic building blocks of a Visual
Basic application. Many form properties correspond
with other control properties that you learned in
the previous section. However, the form is unique
because that it does not reside on a form.
|
The form's Left, Top, Width,
& Height properties all correspond to
the edge of the screen and not to a Form window. |
Some more important properties of form:
- BorderStyle: This
property determines how the Form window responds
to the user's efforts to resize it.
- ControlBox: This
property value of True or False determines whether
the form's Control menu appears.
A Control menu is the menu that appears when you
click a window's icon in the upper-left corner
of the window. The Control menu enables you to
move, size, minimize, maximize, and close a window. |
- Icon: This property
specifies an icon filename for the Windows taskbar
icon that appears when the user minimizes the form.
- MaxButton: This property
determines whether the form contains an active Maximize
window button.
- MinButton: This property
determines whether the form contains an active Minimize
window button.
- Movable: This property
determines whether the user can move the form or
if the form is to remain in its displayed location.
- ShowInTaskbar: This
property determines whether the open form appears
on the user's Windows taskbar.
- StartUpPosition:
This property determines the starting position of
the form on the screen.
- WindowState: This
property determines the size (normal, maximized,
or minimized) of the form.
