.NET

[#1]

Hello everybody.

I had this piece of code in 2010. Now when I re-reference the dll to 2012 . I get a warning message showing:

Public Sub IntersectWith( blah blah blah ) is obsolete. "Use the overload taking IntPrt instead.".  I don't know how . Anybody can help me with this ?

Already appreciated .

Janet,

Here is code.

Dim intpts As New Point3dCollection()

List_Entities(I).IntersectWith(List_Entities(I + 1), Intersect.OnBothOperands, intpts, 0, 0)

I had the same thing come up, and while the "obsolete" version still works for now, it eventually won't.  As it turned out , the function where I had this warning come up was not being used, so my fix has not been tested.

Anyway, seeing that you were just passing zero (as I was) I think you just want to pass New IntPtr(0).

Thanks for Reply ,Chief.

What I need is just finding all intersections of objects Not only intpts(0). Is there anything wrong with the Zero I assigned for

thisGraphicSystemMarker  and otherGraphicSystemMarker ?. Is that what you referring to ?

Maybe this will clear my intention better.

 Dim intpts As New Point3dCollection()
                List_Entities(I).IntersectWith(List_Entities(I + 1), Intersect.OnBothOperands, intpts, 0, 0)
                If intpts.Count = 1 Then
                    ' Do this
else
   ' do something else.
end if.

My reply says New IntPtr (0), not intpts(0)...

I mean to pass New IntPtr(0) for the graphics system markers, but like I said, it doesn't give any compile errors, but I have not tested it to make sure that it works as expected.

Using your code example, changing the function call to this should work:

List_Entities(I).IntersectWith(List_Entities(I + 1), Intersect.OnBothOperands, intpts, IntPtr.Zero, IntPtr.Zero)

Stephen, Thanks. That was the trick.

It is hard for a girl to understand these things.

Regards,

Janet.
