QuestionHow to get Interface to Control after #importing Pin
JohnnyG24-Apr-10 12:31
JohnnyG24-Apr-10 12:31 
I'm using VC6 and the MapWindowGIS control, MapWindowGIS.OCX. It has many interfaces but few examples on how to use it using VC6. I'm kind of new to using COM so my terminology is probably incorrect to some degree.

The problem is I can get to one of the interfaces, IShapeFile, using their example using:

IShapefilePtr* pShapeFile = new IShapefilePtr; 

HRESULT hr = pShapeFile->CreateInstance(__uuidof(Shapefile)); 

CreateInstance(), but when I try this on other interfaces such as IGrid and IGridHeader, CreateInstance() fails with the "Class Not Registered" error (0x80040154).

Since, the control, MapWindowGIS.OCX is registered, and I was able to get the IShapeFile interface, I'm assuming that I need to call QueryInterface() but the IGrid and IGridHeader interfaces are not part of the IShapeFile interface. So, I'm assuming then I need to get a pointer to the MapWindowGIS control but I'm not instantiating it directly since it is #import(ed).

VC6 created the .tli and tlh files and a CWnd derived class from the OCX called, CMap1. Is there something I can call in CMap1 that will return the main object's interface pointer so I can then call QueryInterface()?
