you can try below code to get the object id of a selected object.


 <CommandMethod("TST")> Public Sub TESTObject()
        Dim doc As Document = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument
        Dim db As Database = doc.Database
        Dim ed As Editor = doc.Editor
        Dim peo As PromptEntityOptions = New PromptEntityOptions(vbLf & "Select an object:")
        Dim per As PromptEntityResult = ed.GetEntity(peo)
        If per.Status <> PromptStatus.OK Then
        End If
        Dim id As ObjectId = per.ObjectId
    End Sub
