Same problem with basic windows forms controls:
'GroupBox' is an ambiguous reference between 'System.Windows.Forms.GroupBox' and 'Aspose.Cells.GroupBox' C:\...\mysource.cs 64 17 mysource
You can either:
a) Remove the "using Aspose.Cells;" statement and fully qualify the Aspose object names (i.e. Aspose.Cells.GroupBox) in the source files where you are having problems.
or
b) Move all of the Aspose-related items to another source file that doesn't contain a "using System.Windows.Forms;" statement and use the identifiers without qualification.
Since all of my UI controls are in the same source file that the UI designer uses, and all of the code that handles the Excel access is in another module, I've gone with option (b). Hope this helps!
