Description

Loads an map Document into the MapControl. The map document can be an ArcMap document, an ArcMap template or an ArcReader document. Use the CheckMxFile method to determine  if the specified map document is a valid map document.

Remarks

When LoadMXfile is used the user may be prompted for a password; refer to the tables below to determine when this may occur. Additionally, password prompts may be given if accessing MapDocuments using either the MapControl's PropertyPage, ArcMap or ArcReader; the tables also show in what circumstances this will occur.

Loading Map Documents (*.mxd, *.mxt, *.pmf) which reference IMS Services (with and without security)

* The Connection to the Internet server must have the Save User/ Password setting enabled. This can be set, for example, when using Add Internet Server in the Add Layers Dialog. Additionally, in the case of PMF files the ArcPublisher Cache password in PMF file setting must be enabled.

Loading Published Map Files (*.pmf) (with and without password protection)
