Embedding Macromedia Flash Player v. 9

[José Roca]

 
The Macromedia Flash Player is a multimedia and application player created and distributed by Macromedia. It runs SWF files which can be created by the Macromedia Flash authoring tool, Macromedia Flex or a number of other Macromedia and third party tools.

The following example demonstrates how to create an instance of the ShockWaveFlash player in a SDK window, load and play a movie and setting properties.

Note: To use ATL71.DLL as the container, add $ATL_DLLNAME = "ATL71.DLL" before #INCLUDE "ATL.INC" and change "AtlAxWin" to "AtlAxWin71" in CreateWindowEx.
