We have a 2003 spreadsheet with a check box. We are trying to retrieve
the values from this through a .NET 2008 windows application.
1. We have included Office.Interop.Excel and VBE.Interop.Forms in the
code.
2. We have added the checkbox from the toolbar and not through code.
3. We tried
Excel.CheckBox cb =
(Excel.CheckBox)workSheet.Shapes.Item("CheckBox4") .OLEFormat.Object;
and got
Specified Cast is not Valid
4. We tried
Forms.CheckBox cb =
(Forms.CheckBox)workSheet.Shapes.Item("CheckBox4") .OLEFormat.Object;
and got
Specified Cast is not Valid

Please help.
