IRequiredExtensions::GetFirstExtension method (mmc.h)
The IRequiredExtensions::GetFirstExtension method enables the snap-in to specify the first extension snap-in its list of required extension snap-ins.
Syntax
HRESULT GetFirstExtension(
[out] LPCLSID pExtCLSID
);
Parameters
[out] pExtCLSID
A pointer to the CLSID of the first snap-in in the list of required extension snap-ins.
Return value
This method can return one of these values.
Remarks
MMC calls this method if IRequiredExtensions::EnableAllExtensions returns a value that is not S_OK.
If this method returns S_OK, MMC adds the extension snap-in specified by pExtCLSID and then calls IRequiredExtensions::GetNextExtension to get the next extension snap-in in the list. If any other value is returned, MMC treats the required list as if it were empty by not adding the extension snap-in specified by pExtCLSID and not calling IRequiredExtensions::GetNextExtension.
