Invoke Lisp functions from ObjectARX in AutoCAD 2015

Hi,

I am facing issues while invoking simple Lisp function from ObjectARX in AutoCAD 2015.

The Lisp Function

---------------------------------------

(defun myFunc2()
(alert "myFunc2")
)
(vl-acad-defun 'myFunc2)

If I call this function from ObjectARX the AutoCAD freezes. This is happening only when executing from VLIDE editor. If I use AutoCAD command prompt no issues.

My ObjectARX code to call the above function is...

resbuf *rb_in = acutBuildList(RTSTR, TEXT("myFunc2"),
RTNONE);
resbuf *rb_out = NULL;
int rc = acedInvoke(rb_in, &rb_out);
acutRelRb(rb_in);
rb_in = NULL;
acutRelRb(rb_out);
rb_out = NULL;

Thanks in advance.

Hi,

If you're using .NET (managed code), since AutoCAD 2011, you can use the Application.Invoke() method which wraps acedInvoke().
