Ensuring That ActiveX Is Loaded

AutoCAD Visual LISP

 
Ensuring That ActiveX Is Loaded
 
 
 

ActiveX functionality is not automatically enabled when you start AutoCAD or VLISP, so your programs must ensure that ActiveX is loaded. The following function call accomplishes this:

(vl-load-com)

If ActiveX support is not yet available, executing vl-load-com initializes the AutoLISP ActiveX environment. If ActiveX is already loaded, vl-load-com does nothing.
