This property is read-only at run time and is only applicable for MDI Form type.
Use the MDIActiveForm property to access a form's properties or to invoke its methods — for example:
MDIActiveForm.MousePointer = aformMousePointerHourGlass
This property is applicable to multiple-document interface (MDI) Forms where a button on a toolbar must initiate an action on a control in an MDI child form. For example when a user clicks the Copy button on the toolbar, your code can reference the text in the active control on the MDI child form and copy it to the clipboard (assuming tb is an ATextBox control):
Clipboard.SetText(MDIActiveForm.tb.SelText, acfText)
Note: When an active MDI child form isn't maximized, the title bars of both the parent form and the child form appear active.
The following statement set the MDI Form caption to the name of the active MDI child form::
if MDIActiveForm=Nothing
Caption="My Edit"
else
Caption="My Edit - "+MDIActiveForm.Caption
endif
