Opening Drawings in AutoDesk Map 2005

We've got VBA macros that we've used for several years to manage our drawings (with both AutoCAD and AutoDesk Map). The macros basically open and close a large amount of drawings and extract or change attribute information. The GetObject function is used to open drawings (i.e. - Set AcadDoc = GetObject(FileName)). The macros work fine with AutoCAD 2005, but not with AutoDesk Map 2005. With Map 2005 every time the GetObject function is used to open a drawing, first a temporary drawing (called Drawing1.dwg, Drawing2.dwg, etc) is created, closed, and then the desired drawing is opened. Everytime a temporary drawing is closed a dialog box asking "Save changes to Drawing1.dwg?" is displayed. Macro execution then stops until a user responds to the dialog box.
Has anybody else run across this, and is there a fix?

 

Just a little more information - In looking at previous postings I found a similar problem a user was having with ACAD 2002 (GetObject(strDwgName) (6 replies), Posted by: Mark Propst, Date: Mar/13/04 - 17:30 (GMT))

 

A code change was made which gives a workable solution (i.e. a dialog box pops up on the first drawing, but not on subsequent drawings). Previously each drawing was opened with
Set AcadDoc = GetObject(FileNm)

The new code opens drawings with
On Error Resume Next
Set AcadDoc = AcadApp.Documents.Open(FileNm)
If Err Then
Err.Clear ' Clear the error if it exists
Set AcadDoc = GetObject(FileNm)
Set AcadApp = AcadDoc.Application
End If
