	FALSE	Unlock the class object's associated vector.

Comments

Locking a vector handle has precedence over locking layers within the vector handle. Therefore, if a vector handle is locked, the layers within that vector handle cannot be edited, even if the layers are not locked.

To lock a layer, set the bLocked member of a VECTORLAYERDESC structure to TRUE and update the layer information using the LVectorLayer::SetLayerDesc function.
