Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0025] An embodiment of the present invention provides a host container for playing Flash in WPF, the host container is located in a WPF window, see figure 1 As shown, the WPF form hosts the Flash animation through the host container, and the host container builds a Win32 form based on the graphics device interface GDI+ (Graphics Device Interface, graphics device interface), and sets a transparency of 10% to 15% for the Win32 form, visually It will not cover other controls; the Win32 form loads the ActiveX control to play Flash; the host container periodically captures frame-by-frame screenshots from the Win32 form, and renders the captured pictures in the host container to form an animation playback effect. Since the host container sets a transparency of 10% to 15% for the Win32 form, it will not cover other controls visually, nor wi...

Abstract

The invention discloses a host container and method for playing Flash in a WPF and relates to the field of Flash playback. The host container is located in a WPF window, the WPF window loads Flash animation through the host container, the host container establishes a Win32 window body based on a graphics device interface GDI+, the transparency of 10%-15% is set for the Win32 window body, and other controls are not blocked visually. The Win32 window body loads an ActiveX control to play the Flash. The host container shoots pictures from the Win32 window body at regular intervals, and cut pictures are rendered in the host container to form an animation playing effect.
