Description

Determines whether the specified map document (*.mxd, *.mxt, *.pmf) is a valid map document and can be loaded into the MapControl. The method verifies the file exists and verifies the file internals conform to an expected storage format. The method does not read and validate the entire contents of the file; use the LoadMxFile to do this.
