This screen can only be opened when the password entered by the user is higher than that set by the user, and the current user level is decided by the level password just entered by the user.

 

Macros:

"Open macros" displays a list of macros. The user can select one to execute when press the button. Only compiled macros can be displayed in the drop-down list.

 

The "Label" page of the Screen Button is similar to that of the "Bit Button" control. Because the Screen Button has only one state, its Label page only has Status 1 Text and Status 1 Picture. Apart from that, the functions are the same.

 

The "Advanced" and "Visibility" pages of the "Screen Buttons" are the same as those of the "Bit Button" control, which can be used with reference to the Bit Button.

 

After setting all the properties, click "OK" and the mouse cursor will turn into a cross. Left click in the view area to add the control to the screen.
