Hello Brian, I have a couple of questions regarding the playing of FLC animations: 1) In order to play a WAV file in conjunction with a FLC file, I am using the following code in conjunction with the "Animation Support Libraries R2.0" aaSound ( hAAFlicAnim, // Animation Handle NULL, // This is NULL as we asume MCI extensions have been setup lpszFlicAudioFile, // Name of the audio file ( *.wav, *.mid ) AA_SNDFREEZE ); This will sometimes result with a message box appearing with "The Specified Sound is Invalid". It is also the case that when I use the Animation Player application and hit "Get Sound" from the FILE menu, I don't get the waveaudio device listed in the Sound Devices list box and get the same message as above when I try to select a WAV file. Incidentally, Sequencer and CDAudio always appear. Now, if I change the settings for the MCI Sound Drivers from the Windows Control Panel to different values between 2 and 9 seconds of buffered audio data, the device "waveaudio" reappears in the Animation Player and my application plays the FLC and WAV file successfully!! However, this only works on a random basis across different PC's. Can you shed any light on this problem? It is especially important that we resolve this as we intend to include FLC's with audio on our CD-ROM titles and hence, do not expect the user to have to manually adjust driver settings. We load mciapp.drv to C:\WINDOWS\SYSTEM and make the appropriate changes to WIN.INI and SYSTEM.INI in our installation program for the disc. 2) Can you send a sample of 'C' code which will simply stop a FLC on it's last frame and hold it on the screen. Again this will be in conjunction with an audio file which may be longer or shorter than the duration of the animation. What I've been trying is: // Load the FLIC File hAAFlicAnim = aaLoad ( lpszFlicFile, // Animation File hWnd, // Parent window that owns the animation AA_FULLSCREEN, // wMode ptFlicOrigin.x, // x coord for top left of animation window ptFlicOrigin.y, // y coord for top left of animation window nFlicWidth, // Width of animation window nFlicHeight, // Height of animation window 0, // x coord of the animation displayed at ul 0 ); // y coord of the animation displayed at ul // Set up for play to end on the specified frame if ( (aaSetParm( hAAFlicAnim, AA_LOOPS, NULL, dwFlicFrames )) == NULL ) return (FLIC_ERR); This will indeed stop the FLC but the frame on the screen appears with a "shadow" image of itself. I've also tried: // End the animation with the sound. if ( (aaSetParm( hAAFlicAnim, AA_LOOPS, NULL, MAKELONG(AA_LOOPSOUND, AA_LOOPSOUND) )) == NULL ); return (FLIC_ERR); This doesn't stop the sound and the FLC from looping. In fact, nothing I've tried, other setting play to end on a specified frame, has been able to stop the looping behaviour. Sorry to ask for so much detail on my first visit to this forum, but I hope you will be able to give some pointers. Many Thanks, Donald MacLeod First Information Group U.K.
