DK11 for ActiveX | TatukGIS_XDK11.ITGIS_LayerVector.GetNewUid | Methods | Properties
Gets the Uid for a new shape.
Syntax
// C# public OleVariant GetNewUid();
' VisualBasic Public Function GetNewUid() As OleVariant
// Oxygene public function GetNewUid : OleVariant;
Result
| Type | Description |
|---|---|
| OleVariant | 0 if Uid not assigned (in fact, only for pixel layers) or Uid value. |
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 etc.
