Hi Matthew,
No need to apologize as VSTO is at best confusing for most Excel developers 
I assume You target 2003 and not 2007. Below is all the code in the ThisAddin.VB module. I hope it will be understandable and if not please just ask.
Imports System.Windows.Forms
Public Class ThisAddIn
Private WithEvents MyButtonA As Office.CommandBarButton
Private WithEvents MyButtonB As Office.CommandBarButton
Private Sub ThisAddIn_Startup(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Startup
' Start of VSTO generated code
Me.Application = CType(Microsoft.Office.Tools.Excel.ExcelLocale1033Proxy.Wrap(GetType(Excel.Application), Me.Application), Excel.Application)
' End of VSTO generated code
Dim cbMain As Office.CommandBar = Application.CommandBars(1)
Dim oCtl As Office.CommandBarPopup = CType(cbMain.Controls.Add(Office.MsoControlType.msoControlPopup, Temporary:=True), Office.CommandBarPopup)
Try
With oCtl
.Tag = "MyAddin"
.Caption = "ExcelGroup"
MyButtonA = CType(.Controls.Add(Type:=Office.MsoControlType.msoControlButton), Office.CommandBarButton)
With MyButtonA
.BeginGroup = True
.Caption = "My 1st Procedure"
.FaceId = 296
.Style = Office.MsoButtonStyle.msoButtonIconAndCaption
End With
MyButtonB = CType(.Controls.Add(Type:=Office.MsoControlType.msoControlButton), Office.CommandBarButton)
With MyButtonB
.BeginGroup = True
.Caption = "My 2nd Procedure"
.FaceId = 298
.Style = Office.MsoButtonStyle.msoButtonIconAndCaption
End With
End With
Catch ex As Exception
MessageBox.Show(ex.ToString, My.Application.Info.Title.ToString)
Finally
oCtl = Nothing
cbMain = Nothing
End Try
End Sub
Private Sub ThisAddIn_Shutdown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shutdown
Dim oCtl As Office.CommandBarControl
Try
For Each oCtl In Application.CommandBars.FindControls(Tag:="MyAddin")
oCtl.Delete()
Exit For
Next
Catch ex As Exception
'Skip
Finally
oCtl = Nothing
End Try
End Sub
Private Sub MyButtonA_Click(ByVal Ctrl As Microsoft.Office.Core.CommandBarButton, ByRef CancelDefault As Boolean) Handles MyButtonA.Click
MessageBox.Show("You clicked on the A button")
End Sub
Private Sub MyButtonB_Click(ByVal Ctrl As Microsoft.Office.Core.CommandBarButton, ByRef CancelDefault As Boolean) Handles MyButtonB.Click
MessageBox.Show("You clicked on the B button")
End Sub
End Class
With kind regards,
