If the Visible property of a control is selected, the control displays in the window. If you want a control to be initially invisible, be sure the Visible property is not selected in the General properties page in the control’s Properties view.
Hidden controls do not display by default in the Window painter’s Layout view.
To display hidden controls in the Layout view:
Select Design>Show Invisibles from the menu bar.
To display hidden controls during execution:
Assign the value true to the Visible property of each hidden control:
controlname.Visible = TRUE
