Creating Dispatch Pointers in C++
Applies to: MapObjects 2.0
When using MFC C++ and MO2 you need to create dispatch pointers. To do that
you supply a class ID or GUID. Alternatively, you can supply a text
description. This document lists the text descriptions used by MapObjects
2.0.
TEXT Strings Needed to CreateDispatch Pointers
Within a MFC application that uses MapObjects2
you may need to create a new MO object from scratch, that is, you will not be using an object that is
returned from a function as shown below:
CMoRectangle
m_rect( m_map.GetExtent() );
If you need a new MO object you will also need to create a new dispatch pointer to go with it, as shown below:
CMoRectangle m_rect;
m_rect.CreateDispatch(TEXT("MapObjects2.Rectangle")); The text string that is used to represent the MO GUID for the object in question is not always obvious. The following is a list of all createable MapObjects2 class descriptions.
