Parameters
rClsid
Points to the CLSID of the specified class.
fIsLinkedObject
TRUE if the original object is a linked object; FALSE otherwise.

TRUE
The specified class can be converted to or activated as another class.

Comments
Notes to Implementors
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.
