The following error occurs when opening a read-only Visio Drawing from an ODMA Document Management System (DMS):
An error (110) occurred during the action Open.
Visio cannot write to the file. The file has been opened read-only.
This problem occurs if the NTFS read-only file attribute is set on the document or if ODM_VIEWMODE is specified in ODMSelectDoc.
This is a confirmed problem in Microsoft Visio 2003/2007. Visio will always try to open documents from DMS with read-write access.
