Where the parameter Visibility value is as follows:

Line number parameter meaning
1 sw_hide hides this form and activates other forms.
2 Sw_maximize maximizes the specified form.
3 sw_minimize minimizes the specified form and activates the topmost form sequentially.
4 Sw_restore activates and displays the form. If the form is minimized or maximized, the form reverts to the original large
Small and set. The application specifies the markup when a minimized form is restored.
5 Sw_show activates and displays the form at its current size and position.
6 Sw_showdefault
7 sw_showmaximized activates and maximizes the display of the form.
8 sw_showminimized activates and minimizes the reality form.
9 sw_showminnoactive Minimize the form and keep it active.
Sw_showna displays the form in its current state, keeping it active.
Sw_shownoactivate displays the form in its current size and position and retains its active status.
Sw_shownormal activates and displays a form. If the form is maximized or minimized, the form reverts to its original size and position. When the form is first displayed, the application records the markup
