Applies to: Office 2013 | Visio 2013
Opens a Microsoft Visio document, if it's not already open, and activates the document window.
Multiple OPENFILE function calls are queued and executed in order of evaluation. If the current Visio document is activated for visual (in-place) editing, a new Visio instance is launched with the requested file name.
This function always returns FALSE.
In earlier versions of the Visio application, this function appears as _OPENFILE. Visio versions 4.0 and later accept either style.
