hi all, can you help me how to solve this: My app play flash by using play method in flash.ocx . Now, i want to enable / disable sound of flash, but the flash.ocx doesnot support these methods. So, i find out: 1. Whatever C++ codes that can support flash.ocx to enable / disable flash sound. 2. Functions/Methods from win32 that i can mute/unmute sound from my app.
