Document.FormsDesign Property (Word)
Published: July 16, 2012
True if the specified document is in form design mode. Read-only Boolean.
The FormsDesign property always returns False if it’s used in code that is run from Microsoft Word, but it returns the correct value if it is run through Automation. For example, if you run the example from Microsoft Excel, it will return True if you’re in design mode.
When Word is in form design mode, the Control Toolbox toolbar is displayed. You can use this toolbar to insert ActiveX controls such as command buttons, scroll bars, and option buttons. In form design mode, event procedures don't run, and when you click an embedded control, the control's sizing handles appear.
