Custom AcDbEntity And Dynamic Properties

[Anonymous]

I create two custom entities. And add two new dynamic property for them.But unable to switch property in property inspector when I select them.
When I select one kind of custom entity and other basic enitty from cad, such as AcDbLine. Attribute to switch to normal in property inspector.
Such as,
OPM_DYNPROP_OBJECT_ENTRY_AUTO(CMyProOneName, MyCusOne)
OPM_DYNPROP_OBJECT_ENTRY_AUTO(CMyProTwoName, MyCusTwo)
MyCusOne And MyCusTwo area two kind of custom entities.
CMyProOneName And CMyProTwoName area their property.

I found the GetCurrentSelectionSet in IDynamicPropertyNotify2. It contain all kind of custom entities form my define.
But I had define the dynamic property for them each other.
In general, the GetCurrentSelectionSet in IDynamicPropertyNotify2 should contain a kind of class if I switch class in property inspector.
Such as, I select AcDbLine , AcDbCircle, AcDbArc. When I switch AcDbLine class , the GetCurrentSelectionSet in IDynamicPropertyNotify2 contain AcDbLine only.
And It is right if I define one kind of custom entity only. But now I can't switch class and show their property between MyCusOne And MyCusTwo in property inspector.

Maybe both class has identical display name?

I don't know if it will be problem in static properties.

In dynamic properties, 

STDMETHODIMP CMyProOneName::GetDisplayName (BSTR *pBstrName) {
if ( pBstrName == NULL )
return (E_POINTER) ;
*pBstrName =::SysAllocString (L"CusOneName") ;

return (S_OK) ;
}

I had set identical display name.

I had define CMyProOneName class. Both MyCusOne And MyCusTwo link to CMyProOneName class,

Although I created dynamic property CMyProOneName for MyCusOne only.

OPM_DYNPROP_OBJECT_ENTRY_AUTO(CMyProOneName, MyCusOne) 

Such as, I Select two entities from MyCusOne And MyCusTwo. The CMyProOneName class will run two times. 

The premise condition is I select MyCusOne entity first, and select MyCusTwo entity next. Because CMyProOneName is the property of MyCusOne.

If I don't define property for MyCusTwo and select MyCusTwo entity first,  MyCusOne entity won't link to CMyProOneName class. Nothing will happer. I don't show any property.

Have your custom entities COM-wrappers? GetDisplayName in my post is COM-wraper method and not dynamic property method.

[Anonymous]

virtual Acad::ErrorStatus subGetClassID(CLSID* pClsid) const;

I don't know how to set  pClsid in dynamic property.

I had try in static property.

Is it your meaning?

I mean that every Custom Entity must have its own COM-wrapper. COM-wrapper class has GetDisplayName method which has return display name of entity: http://forums.autodesk.com/autodesk/attachments/autodesk/34/32974/1/com_wrapper_tutorial_2010%5B1%5D.pdf
