[ object, uuid(5BA5F9C4-708D-4E21-8F7D-9737DAA46D2A), dual, nonextensible, helpstring("IMxDrawUiPrEntity interface"), pointer_default(unique) ]
interface IMxDrawUiPrEntity : IMxDrawUiPrBase;MxDrawUiPrPoint.idl
例如:VC COM调用
IMxDrawUiPrEntityPtr selEnt;
selEnt.CreateInstance(__uuidof( MxDrawXLib::MxDrawUiPrEntity ));
selEnt->put_message(_T("选择图像对象"));
if(selEnt->go() != 1)
return;
IMxDrawEntityPtr spEnt(selEnt->Entity());
if(spEnt == NULL)
return;
IMxDrawImageMarkPtr spImage;
spEnt->QueryInterface(&spImage);
if(spImage == NULL)
return;
spImage->put_ImageFile(_T("d:\mxcad.jpg"));
