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.

OpenGL and DirectX engines lock the vector handle automatically.

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