Problem with custom blockReference

[Anonymous]

Hi,

I made a class inherited from AcDbBlockReference:

class PICBlock : public AcDbBlockReference
{
public:
	ACRX_DECLARE_MEMBERS(PICBlock);
	static void makeMembers(AcRxMemberCollectionBuilder& collectionBuilder, void* customData);

protected:
	static Adesk::UInt32 kCurrentVersionNumber;

public:
	PICBlock();
	PICBlock(const AcGePoint3d& position, AcDbObjectId  blockTableRec);

	Acad::ErrorStatus dwgOutFields(AcDbDwgFiler* pFiler) const final;
	Acad::ErrorStatus dwgInFields(AcDbDwgFiler* pFiler)final;

	Acad::ErrorStatus dxfOutFields(AcDbDxfFiler* pFiler) const final;
	Acad::ErrorStatus dxfInFields(AcDbDxfFiler* pFiler)final;

	Acad::ErrorStatus subClose()override;
	void setManagedWrapper(gcroot<Autodesk::PIC::MgPICBlock^> p);

private:

	gcroot<Autodesk::PIC::MgPICBlock^> m_pManaged; // the managed wrapper pointer.  
};


Adesk::UInt32 PICBlock::kCurrentVersionNumber = 1;

ACRX_DXF_DEFINE_MEMBERS_WITH_PROPERTIES(
	PICBlock, AcDbBlockReference,
	AcDb::kDHL_CURRENT, AcDb::kMReleaseCurrent,
	AcDbProxyEntity::kNoOperation, PIC-BLOCK,
	PICBLOCK
	"|Product Desc:     PIC-ACAD"
	"|Company:          So.Build"
	"|WEB Address:      www.sobuild.fr",
	PICBlock::makeMembers
	)


void PICBlock::makeMembers(
	AcRxMemberCollectionBuilder& collectionBuilder,
	void* customData)
{
	readFromResource("PIC_Attributs.xml", collectionBuilder);
}


PICBlock::PICBlock() : AcDbBlockReference()
{
	//
}

PICBlock::PICBlock(const AcGePoint3d& position, AcDbObjectId  blockTableRec) : AcDbBlockReference(position, blockTableRec)
{
	//
}

Acad::ErrorStatus PICBlock::dwgOutFields(AcDbDwgFiler* pFiler) const
{
	Acad::ErrorStatus retStat = AcDbBlockReference::dwgOutFields(pFiler);
	if (retStat != Acad::eOk)
		return retStat;

	retStat = pFiler->writeUInt32(PICBlock::kCurrentVersionNumber);
	return retStat;
}

Acad::ErrorStatus PICBlock::dwgInFields(AcDbDwgFiler* pFiler)
{
	assertWriteEnabled();
	Acad::ErrorStatus retStat = AcDbBlockReference::dwgInFields(pFiler);
	if (retStat != Acad::eOk)
		return retStat;

	Adesk::UInt32 uiVersion = 0;
	retStat = pFiler->readUInt32(&uiVersion);
	return retStat;
}

Acad::ErrorStatus PICBlock::dxfOutFields(AcDbDxfFiler* pFiler) const
{
	Acad::ErrorStatus retStat = AcDbBlockReference::dxfOutFields(pFiler);
	if (retStat != Acad::eOk)
		return retStat;

	retStat = pFiler->writeUInt32(AcDb::kDxfInt32, PICBlock::kCurrentVersionNumber);
	return retStat;
}

Acad::ErrorStatus PICBlock::dxfInFields(AcDbDxfFiler* pFiler)
{
	assertWriteEnabled();
	Acad::ErrorStatus retStat = AcDbBlockReference::dxfInFields(pFiler);
	if (retStat != Acad::eOk)
		return retStat;

	resbuf data;
	Adesk::UInt32 uiVersion = 0;
	retStat = pFiler->readItem(&data);
	if ((data.restype != AcDb::kDxfInt32) || (retStat != Acad::eOk))
		return (retStat != Acad::eOk) ? retStat : Acad::eNotApplicable;
	uiVersion = data.resval.rint;

	return retStat;
}

Acad::ErrorStatus PICBlock::subClose()
{
	Acad::ErrorStatus es;
	if ((es = AcDbBlockReference::subClose()) != Acad::eOk)
		return es;

	if (isWriteEnabled() == Adesk::kTrue)
	{
		//You have to cast it back to the managed type to do a null check:
		if (static_cast<Autodesk::PIC::MgPICBlock^>(m_pManaged) != nullptr)
		{
			// Call the method on the wrapper which will propagate to all managed
			// listeners of this event...
			m_pManaged->PICBlockModified(ToObjectId(objectId()));
		}
	}

	return Acad::eOk;
}

void PICBlock::setManagedWrapper(gcroot<Autodesk::PIC::MgPICBlock^> p)
{
	m_pManaged = p;
}


ACDB_REGISTER_OBJECT_ENTRY_AUTO(PICBlock)

but I can't have attributes I have an exception "illegal entity type"

and I can't create a dynamic block.

What I'm doing wrong ?

Thanks.

Classes derived from AcDbBlockReference cannot have AcDbAttributes.
