Working with VS 2019

Before using Add-in Express, I used to work with the Workbook_Open Event by placing the code in ThisAddIn.vb 


Public Class ThisAddIn
    '~~> Show hide ribbon based on whether a workbook is opened or not
    Private Sub Application_WorkbookOpen(ByVal doc As Excel.Workbook) Handles Application.WorkbookOpen
        If Application.Workbooks.Count > 0 Then
            If Globals.Ribbons.Ribbon1.Tab1.Visible = False Then Globals.Ribbons.Ribbon1.Tab1.Visible = True
        End If
    End Sub
End Class


How do I do this in Add-in Express?

Hello (BTW, whats your-name?)

You put an Excel Events component onto the add-in module and handle its WorkbookOpen event. A Ribbon tab is controlled using an ADXRibbonTab component that you also put onto the module. 


Imports Excel = Microsoft.Office.Interop.Excel
...
    Private Sub AdxExcelAppEvents1_WorkbookOpen(sender As Object, hostObj As Object) Handles AdxExcelAppEvents1.WorkbookOpen
        Dim doc As Excel.Workbook = CType(hostObj, Excel.Workbook)
        Dim workbooks As Excel.Workbooks = ExcelApp.Workbooks
        If workbooks IsNot Nothing Then
            If (workbooks.Count > 0) Then
                If Me.AdxRibbonTab1.Visible = False Then Me.AdxRibbonTab1.Visible = True
            End If
            Marshal.ReleaseComObject(workbooks) : workbooks = Nothing
        End If
    End Sub

You are welcome, Mike.

BTW, the Add-in Express manual is the PDF file in the folder {Add-in Express}\Docs on your development PC.

Pay attention to section Development Tips. We will consider renaming it to Best Practices.

Yes I am using that. Couldn't find certain things (Sometimes I can be really blind) in the Excel section for example what you recomended "MyAddin28.CurrentInstance.ExcelApp" in my other post. For the rest, I guess I am managing prettry well I must say. :)

Thanks Again!

That's not blindness, this means something is missing in the structure of the manual. If you find something you don't like or, well, anything, please let me know.
