Option strictI'd assume on, but then so many things break looks like it will take long time to rewrite existing prog. example: Option Strict On disallows implicit conversions from 'Object' to 'Autodesk.AutoCAD.Interop.AcadApplication'. but the variable wasn't declared as Object it was early bound Private m_AcadApp As AcadApplication = Nothing ....then later Private Function GetAutoCADInstance() As AcadApplication Try m_AcadApp = Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication Catch ex As Exception End Try Return m_AcadApp End Function sorry but i don't see the implicit conversion thanks for any info mark Am 25.04.2010 20:23, schrieb mp:

Did you consider this? Are you sure that 'AcadApplication' will _always_ be of type Autodesk.AutoCAD.Interop.AcadApplication? If you are, then cast the object to that type before the assignment. -- Armin

The type of the 'Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication' property (as I assume) should not be 'Object'. However, maybe this is out of your control. In this case, read the documentation on the property carefully. Maybe a cast ('DirectCast') is required to cast the returned value to 'AcadApplication'. -- M S Herfried K.
