[xiaohuli170]

I used the cocoa of MAC to develop a plugin with safari , I used the method is : changed the plugin's MIME TYPES is application/x-shockwave-flash and extensions is swf, so when safari lanched , it will add my plugin , but Now have a problem : when the safari page showing , the swf embed it don't show , because I don't know the method of showing swf with adobe flashplayer again. And how to implement the method to show the swf with flashplayer after the safari page show all swf files in it ? Thanks a lot!
