atl和VB比起来的优势在哪里？

大侠，给我点信心吧。
VB Code:
If objInspector.CurrentItem.Class = olMail Then

My ATL code:
CComQIPtr<Outlook::_Inspector> spInspector(Ctrl);


//we only handle the first selected email
IDispatch *ppItem;
//get the mail item
spInspector->get_CurrentItem(&ppItem);

//the mailitem we want!
//-------------below line have some problem---------
//because I do not know what is ppItem's item, may be mailitem or
//note item or contact item, I have to get_Class() and know it type.
//Now the key problem is IDispatch* do not have get_Class Method and
// I do not find <Outlook::Item> type in the type library
//what should I do?
CComQIPtr<Outlook::_MailItem> spItem(ppItem);
//temporary variable is not useful

enum OlObjectClass type;
spItem->get_Class(&type);
ppItem->Release();
if(type!=olMail){
return;
}


//CComQIPtr<Outlook::MailItem> spMailItem(Ctrl);
}

楼上，我需要励志吗？

这个场合C++确实用起来很麻烦，但是在有些场合中，C++要比VB方便，如DirectX编程方面
