// C++ Builder
public:
  virtual TGIS_Uid* GetNewUid(void);

Result

Type Description
TGIS_Uid

Remarks

Use this method to find the Uid for a new shape. It simply uses GetLastUid method to determine the next available id. See example in GetLastUid.

When using this operation, never call any function which uses FindFirst..FindNext (i.e., any function which iterates through the shapes using it). So never use inside an operation like Locate, PaintScope>, etc.
