Allowing the User to Specify Devices and Files
You can associate a device or file with an existing MCIWnd window by using the MCIWndOpenDialog
, and MCIWndOpenInterface
macros, and the GetOpenFileNamePreview
To let a user of your application select a file to play, use MCIWndOpenDialog
. This macro displays the Open
dialog box (shown following) for choosing a file and associates the selected
file with the current MCIWnd window.
You can let a user of your application select a file to associate with an
MCIWnd window and preview that file by using GetOpenFileNamePreview
. The GetOpenFileNamePreview
function displays the Open
dialog box for choosing a file and lets the user preview (play) its contents.
When the name of an existing file is specified in the dialog box, GetOpenFileNamePreview
provides a small control to let the user preview the contents of the file.
You can associate a specified file, selected with GetOpenFileNamePreview
or specified in another manner, with an MCIWnd window by using MCIWndOpen
You can also use MCIWndOpen
to specify a device to associate with an MCIWnd window. For example, you can
use a device name, such as "CDAudio".
To associate an MCIWnd window with a file interface or data-stream interface
to multimedia data, use the MCIWndOpenInterface
macro. For more information about file and data-stream interfaces, see AVIFile Functions and Macros
Before associating a new file or device with an MCIWnd window, MCIWndOpenDialog
close any device currently associated with the window. Your application does
not need to close any open devices before using these macros.
