ObjectClass

Anonymous — Fri, 09 Apr 2010 03:31:29 GMT

Help. I need ObjectClass in ObjectId but my Visual Studio 2008 does not recognize ObjectClass as one of the properties of ObjectId what is wrong with my code?

Dim bObject As New EditorInput.PromptNestedEntityOptions("")
Dim opt As EditorInput.PromptPointOptions = New EditorInput.PromptPointOptions("Pick point: ")
bObject.NonInteractivePickPoint = myEd.GetPoint(opt).Value
bObject.UseNonInteractivePickPoint = True

Dim bRes As EditorInput.PromptNestedEntityResult = myEd.GetNestedEntity(bObject)
If bRes.Status = EditorInput.PromptStatus.OK Then
Using ta As Transaction = tm.StartTransaction
myEnt = ta.GetObject(bRes.ObjectId, OpenMode.ForRead)
Dim id As DatabaseServices.ObjectId = myEnt.ObjectId
id.ObjectClass <---- does not exists
end using
end if

Hi

The ObjectClass property isn't available prior ObjectARX 2010.

Prior 2010, you can use the Entity.GetType() method

or evaluate the entity type :
{code}if (myEnt is Polyline)
{
// Do something here with the polyline
}{code}

or try an explicit cast to the requiered type (Curve in this example):
{code}Curve curveEnt = ta.GetObject(bRes.ObjectId, OpenMode.ForRead) as Curve
if (curveEnt != null)
{
// Do something here with the curve
}{code}

ObjectClass is available in 2009 or later.

Oops!...
I upgraded from 2007 to 2010, so I don't know much about 2008 and 2009.
