Hey,

I am running RC0.  I ran the "Shared add-in" project wizard to create the boilerplate for an
 addin.  I am using early-bound calls to add a command bar (which is successful) and then ad
d a button to it (throws ArgumentException, "The parameter is invalid", no info on which par
ameter).  Here is my code:

        try
        {
                m_ExcelApp = (Excel.Application) appObject;
                m_AppType = Type.GetTypeFromProgID( "Word.Application" );
                string barName = "MyBar10";
                string btnName = "Button";
                bool bMenuBar = false;
                bool bTemp = false;
                bool bTemp2 = false;
                Office.CommandBar cmdBar;
                Office.CommandBarControl cmdBarCtrl;
                int id = 0;
                int before = 0;

                // This one works
                cmdBar = m_ExcelApp.CommandBars.Add( barName, MsoBarPosition.msoBarFloating,
                        bMenuBar, bTemp );

                // This one fails - "The parameter is invalid"
                cmdBarCtrl = cmdBar.Controls.Add( MsoControlType.msoControlButton, id,
                        btnName, before, bTemp2 );
                // Kaboom!
        }
        catch( System.Exception e )
        {
                Trace.WriteLine( e.Message );
        }

I have tried about two dozen variations of the cmdBar.Controls.Add method, from setting all 
the parameters after the first to null (they are optional parameters after all), to no avail
.  Anyone have any suggestions?  Switch to VB ;-)?  I may try late-bound calls next.

Thanks,

Eric
