|< 1||An error occurred. Refer to Return Codes.|
This function is used to update the object information of the class object.
To use this method, declare a variable of type VECTORCIRCLE and pass the address to the LVectorCircle::LockObject () function. After modifying the vector object settings, call LVectorCircle::UnlockObject (). LVectorCircle::LockObject () and LVectorCircle::UnlockObject () should always be called in pairs.
Before an object has been added to the LVectorBase object, using LVectorBase::AddObject or LVectorLayer::AddObject, LVectorCircle::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 [LVectorCircle: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 LVectorCircle::UnlockObject ().
To get the current object information for a class object, call LVectorCircle::LockObject.
LVectorCircle::LockObject and LVectorCircle::UnlockObject must be called in pairs.
