Visual Basic (Usage)

Full path and name of file to open


This event is only fired when opening these SolidWorks files: parts, drawings, and assemblies. It is not fired when opening files like templates, translator files, and so on.


This event is fired before SolidWorks begins loading the file. A SolidWorks file can be opened in many ways; for example, File, Open in the user interface, ISldWorks::OpenDoc6 in the API, Load Model from a Detached drawing, Lightweight component being resolved, and so on. This event is fired in all of these cases.


If you want to allow SolidWorks to open the file, return S_OK (or 0) from the handler. If you do not want to allow SolidWorks to open the file, return S_false (or any code other than S_OK) from the handler.


The event that occurs after this event is DocumentLoadNotify.


If developing a C++ application, use swAppFileOpenPreNotify to register for this notification.


SolidWorks 2004 SP4, Revision Number 12.4
