SUMMARY

The AVIWIN sample demonstrates how you can open and close AVI files in the background while playing another AVI file. This sample also demonstrates the MCI_WINDOW and MCI_PUT commands.

NOTE: The Open command takes 1 to 2 seconds to complete. On slower machines, the playback of one AVI is slightly disrupted if you try to open another AVI file in the background. This disruption might cause some video frames to be dropped or skipped.

When you run the AVIWIN.EXE file, remember that you can only play an AVI if you have already opened it. The menu items are always enabled, even when the command should not be run. For example, the Play menu commands are always enabled, even when the MCI_PLAY command would fail. If you try to play an AVI before you open it, you get the following message box: 

   Reminder: Did you Open the first/second AVI? [Yes] [No]
If you click "Yes," you see the error message that returned from the mciSendCommand() function. If you click "No," the focus returns to the AVIWIN.EXE file, and you are then able to open an AVI file.
