rClsid
[in] The
CLSID of the class for which the information is required.
fIsLinkedObject
[in] TRUE if
the original object is a linked object; FALSE otherwise.

of the original class.
Return Values
TRUE
The specified
class can be converted to or activated as another class.

OleUICanConvertOrActivateAs searches the registry for classes that include wFormat
in their \Conversion\Readable\Main, \Conversion\ReadWriteable\Main, and
\DataFormats\DefaultFile entries.
This function
is useful for determining if a Convert... menu item should be disabled. If the
CF_DISABLEDISPLAYASICON flag is specified in the call to OleUIConvert, then the Convert... menu
item should be enabled only if OleUICanConvertOrActivateAs returns TRUE.
