Interesting bugs in automation CorelDraw X7 + VS2010
First bug:
This code (vb.net) gives an error:

Dim cdrapp As New VGCore.Application

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click       
        Try
            cdrapp.ActiveShape.Outline.Justification = VGCore.cdrOutlineJustification.cdrOutlineJustificationOutside
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try
    End Sub

But this code (VBA) works fine:

Public Sub test()
  ActiveShape.Outline.Justification = cdrOutlineJustificationOutside
End Sub

Second bug:

This code (vb.net) gives an error:

Dim cdrapp As New VGCore.Application

    Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click       
        Try
            cdrApp.FrameWork.Automation.InvokeItem("13f1794d-bf6b-455a-969c-47f80bd6b912") 'select master shape for clones
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try
    End Sub

But this code (VBA) works fine:

Public Sub test()
 Application.FrameWork.Automation.InvokeItem ("13f1794d-bf6b-455a-969c-47f80bd6b912")'select master shape for clones
End Sub

Can you give more details? What errors do you get?

For Justification - Error:
"Attempt to read or write Protected Memory. This is often an indicating that other memory is corrupt"

For Automation.InvokeItem - Error:
"The stub received bad data. (Exception from HRESULT: 0x800706F7)"

Has anyone figured this out? I am hitting the same issue. It seems to be the same in CorelDraw 2018 also.

Anyone have any ideas???
