Assembly: Microsoft.Office.Interop.Excel (in microsoft.office.interop.excel.dll)
If you want to work with a subset of the shapes on a document—for example, to do something to only the AutoShapes on the document or to only the selected shapes—construct a ShapeRange collection that contains the shapes you want to work with.
If you want to do something (like delete or set a property) to all the shapes on a sheet at the same time, select all the shapes and then use the ShapeRange property on the selection to create a ShapeRange collection object that contains all the shapes on the sheet, and then apply the appropriate property or method to the ShapeRange object.
Use Shapes(index), where index is the shape’s name or index number, to return a single Shape object.
Use Shapes.Range(index), where index is the shape’s name or index number or an array of shape names or index numbers, to return a ShapeRange collection that represents a subset of the Shapes collection.
An ActiveX control on a sheet has two names: the name of the shape that contains the control, which you can see in the Name box when you view the sheet, and the code name for the control, which you can see in the cell to the right of (Name) in the Properties window. When you first add a control to a sheet, the shape name and code name match. However, if you change either the shape name or code name, the other isn’t automatically changed to match.
You use the code name of a control in the names of its event procedures. However, when you return a control from the Shapes or OLEObjects collection for a sheet, you must use the shape name, not the code name, to refer to the control by name. For example, assume that you add a check box to a sheet and that both the default shape name and the default code name are CheckBox1. If you then change the control code name by typing chkFinished next to (Name) in the Properties window, you must use chkFinished in event procedures names, but you still have to use CheckBox1 to return the control from the Shapes or OLEObjects collection
