IDispatch::GetTypeInfoCount
pctinfo)
unsigned int FAR* pctinfo
Retrieves the number of type information interfaces that an object provides
(either 0 or 1).
Parameters
pctinfo
Points to location that receives the number of type information interfaces
that the object provides. If the object provides type information, this number is
1; otherwise the number is 0.
Return Value
The SCODE obtained from the returned HRESULT is one of the following:
SCODE
| Meaning
| S_OK
| Success
| E_NOTIMPL
| Failure
|
Comments
The function may return zero, which indicates that the object does not provide
any type information. In this case, the object may still be programmable
through IDispatch, but does not provide type information for browsers, compilers, or other
programming tools that access type information. This may be useful for hiding an
object from browsers or for preventing early binding on an object.
Example
This code from the Lines sample file LINES.CPP implements the GetTypeInfoCount member function for the CLines class. (OLE Automation object.)
STDMETHODIMP
CLines::GetTypeInfoCount(UINT FAR* pctinfo)
{
return NOERROR;
}

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
