ArcObjects Library Reference (ArcMapUI)

MxDocument CoClass

Esri Mx Document.

Product Availability

Available with ArcGIS Desktop.

Description

The map document (MxDocument) is the ArcMap running application. The overall role of the map document is to control the representation of data . This object implements several interfaces including IMxApplication and IDocument. IMxDocument is a starting point for accessing most of the other ArcMap objects including the collection of maps, the page layout, and the style gallery. The IDocument interface provides access to the document's title, type, accelerator table, CommandBars collection, and VBA project.

There is one map document per session of ArcMap. Instantiating a new MxDocument starts a new ArcMap application. Actually, creating a new MxDocument really creates a new Application object which in turn co-creates a new MxDocument.

To edit the contents of a map document saved to a file (*.mxd) outside of an ArcMap session or without instantiating a new Application (ArcMap process), see IMapDocument. IMapDocument provides the ability to edit and save the contents of a map document.

Supported Platforms

Windows

Extended Error Information

Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
