HRESULT SetHelpContext(
unsigned long dwHelpContext
);
Sets the Help context ID for retrieving general Help information for the type library.
The return value of the returned HRESULT is one of the following:
| Return value | Meaning |
|---|---|
| S_OK | Success. |
| STG_E_INSUFFICIENTMEMORY | Out of memory. |
| E_OUTOFMEMORY | Out of memory. |
| E_INVALIDARG | One or more of the arguments is invalid. |
| TYPE_E_INVALIDSTATE | The state of the type library is not valid for this operation. |
Calling SetHelpContext with a Help context of zero is equivalent to not calling it at all, because zero indicates a null Help context.
