MS Office Word Ribbon Addin

Hi guys.

I've been programming for a while but am new to programming Office Applications and AddIns in VS2010 so I hope you will bear with me.

I've created a new project WordAddIn1
and added a Ribbon and configured it with buttons

In my ThisAddIn_Startup code I want to interogate the current document and based on whether a customproperty exists or not, I want to disable the buttons.

but when I do the btn1.enable = false I get a error... as per the image.

I'm sure this is a basic error on my part so many thanks for the help in moving forward.

btnAcceptErr
Private Sub ThisAddIn_Startup() Handles Me.Startup

        wrdDoc = Me.Application.ActiveDocument

        Dim properties As Microsoft.Office.Core.DocumentProperties
        properties = CType(wrdDoc.CustomDocumentProperties, Office.DocumentProperties)

        If ReadDocumentProperty("docProperty") = Nothing Then
            btn1.enable = false
        End If

...
    End Sub

Private Function ReadDocumentProperty(ByVal propertyName As String) As String
        Dim properties As Office.DocumentProperties
        properties = CType(wrdDoc.CustomDocumentProperties, Office.DocumentProperties)

        Dim prop As Office.DocumentProperty

        For Each prop In properties
            If prop.Name = propertyName Then
                Return prop.Value.ToString()
            End If
        Next

        Return Nothing

    End Function

At your Ribbon1.Designer.cs, check that: (I assume your ribbon is called Ribbon1)
private Microsoft.Office.Tools.Ribbon.RibbonButton btnAccept

is internal or public. (You can do this using the property window as well)

Apologies in VB will be : shared or public
Private Dim btnAccept As Microsoft.Office.Tools.Ribbon.RibbonButton
Next time include the question in the VSTO zone.

Also, the ribbon button names will not be directly accessible from within the ThisAddin class - you can access them through Globals like so:

Globals.Ribbons.MyRibbonName.MyButtonName

Where MyRibbonName is the name of the ribbon and MyButtonName is the najme of the button e.g. btnAccept.
