Suppressing the dialog window for all messages.

Hello,

I am trying to write a batch routine that will have no user interaction. I'm
using AutoCAD 2004 and the file that is giving me problems is an AutoCAD
2000 file. The dialog box I get when I try opening this file is as follows:

"This drawing was last saved by an earlier version of this application.
Saving the drawing will upgrade it to the current version which is
incompatable with the earlier version."

First of all I don't care of the incompatability problem due to the fact
that I'm opening all of the files in READ ONLY mode. I have tried setting
EXPERT to 5 using s::starup, however I still get this message. The odd thing
is, is that for most of my other AutoCAD 2000 and even AutoCAD 14 files I
don't get this dialog popping up.

Here is a sample of my VB.NET code:

If objAcadApp.Documents.Count < 1 Then
objAcadDoc = objAcadApp.Documents.Add("acad.dwt")
Else
objAcadDoc = objAcadApp.ActiveDocument
End If
objAcadApp.Visible = True
objAcadDoc.SetVariable("SDI", 0)

For Each objDataRow In objFileDataTable.Rows
'Open DWG file
objAcadDoc =
objAcadApp.Documents.Open(Path.Combine(objDataRow.Item("File_Path"),
objDataRow.Item("File_Name")), objReadOnly)
objAcadDoc.SetVariable("SDI", 0)

 

This is not the best solution but may be a temp fix.
