MCIWndOpen macro

The MCIWndOpen macro opens an MCI device and associates it with an MCIWnd window. For MCI devices that use data files, this macro can also open a specified data file, name a new file to be created, or display a dialog box to let the user select a file to open. You can use this macro or explicitly send the MCIWNDM_OPEN message.
