How to check from .net code whether "Trust access to the VBA project object model" is enabled or not for an Excel application?

Manually I can check it from Excel application- File>Options>Trust Center>Trust Center Settings>Macro Settings>Trust access to the VBA project object model

Answer 1

This worked for me

Function VBATrusted() As Boolean
    On Error Resume Next
    VBATrusted = (Application.VBE.VBProjects.Count) > 0
End Function

Private Sub Workbook_Open()
    If Not VBATrusted() Then
    MsgBox "No Access to VB Project" & vbLf & _
      "Please allow access in Trusted Sources" & vbLf & _
      "File > Options > Trust Center > Trust Center Settings > Macro Settings > Trust Access..."
    End If
End Sub
