    [InAttribute] unsigned int dwCookie
)
abstract LockDocument : 
        grfRDTLockType:uint32 * 
        dwCookie:uint32 -> int 
function LockDocument(
    grfRDTLockType : uint, 
    dwCookie : uint
) : int
Parameters
- grfRDTLockType
 Type: System.UInt32
 [in] Flag whose value is taken from the _VSRDTFLAGS enumeration.
- dwCookie

Remarks
COM Signature
From vsshell.idl:
HRESULT IVsRunningDocumentTable::LockDocument(
   [in] VSRDTFLAGS grfRDTLockType,
   [in] VSCOOKIE   dwCookie
);
The dwCookie parameter is the same value that is returned from the FindAndLockDocument or RegisterAndLockDocument methods.
