AcDbObjectContextManager pointer to incomplete class not allowed

karl.sch1983 — Mon, 01 Sep 2025 02:23:14 GMT

I am trying to run the below code from this post

AcString annoName(_T("Scale 1:125")); AcDbObjectContextManager* cManager = acdbCurDwg()->objectContextManager(); AcDbObjectContextCollection* col = cManager->contextCollection(ACDB_ANNOTATIONSCALES_COLLECTION); col->removeContext(annoName);

Keep getting error - Error (active) E0393 pointer to incomplete class type "AcDbObjectContextManager" is not allowed
Can anyone guide how to proceed? I am simply trying to get the current annotation scale collection and all posts show the same approach of getting the contextManager and then the contextcollection. But it is not working for me. Please provide some guidance. I am stuck.

Did you include the headers?

#include "dbObjectContextManager.h" #include "dbObjContext.h" #include "dbAnnotationScale.h" #include "dbObjectContextCollection.h" #include "dbObjectContextInterface.h" static void AcRxPyApp_idoit(void) { AcDbObjectContextManager* cManager = acdbCurDwg()->objectContextManager(); AcDbObjectContextCollection* col = cManager->contextCollection(ACDB_ANNOTATIONSCALES_COLLECTION); for (std::unique_ptr<AcDbObjectContextCollectionIterator> iter(col->newIterator()); !iter->done(); iter->next()) { AcString annoName; AcDbObjectContext* ctx = nullptr; if (iter->getContext(ctx) != eOk) continue; if(ctx->getName(annoName) != eOk) continue; acutPrintf(_T("\nName = %ls"), (const wchar_t*)annoName); } }

Feeling stupid!! You are right. I was missing the

#include "dbObjectContextManager.h"

Thank again @daniel_cadext . Really appreciate your time.
