This function is used to update the object information of the class object.
To use this method, declare a variable of type VECTORLINE and pass the address to the LVectorLine::LockObject () function. After modifying the vector object settings, call LVectorLine::UnlockObject (). LVectorLine::LockObject LVectorLine::LockObject () and LVectorLine::UnlockObject () should always be called in pairs.
Before an object has been added to the LVectorBase object, using LVectorBase::AddObject or LVectorLayer::AddObject, LVectorLine::UnlockObject () can be used to change ALL properties of an object. However, once the object has been added to the LVectorBase object, some properties cannot be changed using LVectorLine::UnlockObject (). Specifically, nPointCount, *Point, pszText, and pbyType cannot be changed. However, as long as the number of points does not change, the coordinates of the individual points can always be modified using LVectorLine::UnlockObject ().
To get the current object information for a class object, call LVectorLine::LockObject.
LVectorLine::LockObject and LVectorLine::UnlockObject must be called in pairs.
