|
|
* MCIWnd
|
|
*
|
|
* the MCIWnd window class is a window class for controling MCI devices
|
|
* MCI devices include, wave files, midi files, AVI Video, cd audio,
|
|
* vcr, video disc, and others..
|
|
*
|
|
* to learn more about MCI and mci command sets see the
|
|
* "Microsoft Multimedia Programmers's guide" in the Win31 SDK
|
|
*
|
|
* the easiest use of the MCIWnd class is like so:
|
|
*
|
|
* hwnd = MCIWndCreate(hwndParent, hInstance, 0, "smag.wav");
|
|
* ...
|
|
* MCIWndPlay(hwnd);
|
|
* MCIWndStop(hwnd);
|
|
* MCIWndPause(hwnd);
|
|
* ....
|
|
* MCIWndDestroy(hwnd);
|
|
*
|
|
* this will create a window with a play/pause, stop and a playbar
|
|
* and start the wave file playing.
|
|
*
|
|
* mciwnd.h defines macros for all the most common MCI commands, but
|
|
* any string command can be used if needed. Note unlike the
|
|
* mciSendString() API, no alias or file name needs to be specifed.
|
|
*
|
|
* MCIWndSendString(hwnd, "set hue to bright");

|

|
|
*
|
|
* @api HWND | MCIWndCreate | This function creates an MCIWnd window for
|
|
* using MCI services.
|
|
*
|
|
* @parm HWND | hwndParent | Specifies a handle to the parent window.
|
|
*
|
|
* @parm HINSTANCE | hInstance | Specifies the window instance.
|
|
*
|
|
* @parm DWORD | dwStyle | Specifies any flags for the window style.
|
|
* If you do not specify any of the WS_ styles, your window will
|
|
* use WS_CHILD, WS_BORDER, and WS_VISIBLE if you specify a non-NULL
|
|
* parent window, and WS_OVERLAPPEDWINDOW and WS_VISIBLE otherwise.
|
|
* Thus, to create an invisible child window, specify WS_CHILD to
|
|
* prevent the default flags from being used.
|
|
*
|
|
* The following styles are defined in addition to
|
|
* those defined for <f CreateWindow>.
|
|
*
|
|
* @flag MCIWNDF_NOAUTOSIZEWINDOW | Inhibits the changing of
|
|
* the window size when the image size changes. By default,
|
|
* the window size changes automatically to reflect changes in
|
|
* image size. The window also automatically resizes when a
|
|
* new file opens or closes.
|
|
*
|
|
* @flag MCIWNDF_NOAUTOSIZEMOVIE | Prevents stretching the
|
|
* image when window size changes. For MCI devices
|
|
* that display video in a window, MCIWnd normally
|
|
* resizes the image to fill the window.
|
|
*
|
|
* @flag MCIWNDF_NOPLAYBAR | Inhibits the display of the playbar.
|
|
* By default, a playbar is displayed. The default controls on
|
|
* on the playbar include the PLAY, STOP, RECORD,
|
|
* and MENU buttons as well as a trackbar to set the
|
|
* media position.
|
|
*
|
|
* Holding a shift key down while pressing the PLAY button plays
|
|
* the media backwards (if supported). For windowed devices,
|
|
* holding the control key down while pressing the PLAY
|
|
* button plays the device in FULLSCREEN mode if supported.
|
|
*
|
|
* @flag MCIWNDF_NOMENU | Inhibits the display of a menu button
|
|
* on the playbar and inhibits display of the popup menu
|
|
* normally available when the right mouse button
|
|
* is pressed when the cursor is over the window.
|
|
*
|
|
* @flag MCIWNDF_RECORD | Displays a record button on the playbar
|
|
* or menu, and adds a new file command to the menu.
|
|
* By default, only nondestructive
|
|
* commands are available on the playbar and menu.
|
|
*
|
|
* @flag MCIWNDF_NOERRORDLG | Inhibits display of an error dialog
|
|
* box for MCI errors. Applications can use <f MCIWndGetError>
|
|
* to determine the most recent error.
|
|
*
|
|
* @flag MCIWNDF_NOTIFYMODE | Has MCIWnd notify the parent
|
|
* window when the mode of the MCI device changes.
|
|
* Whenever the mode changes (for example,
|
|
* from stop to play) the parent window receives a
|
|
* <m MCIWNDM_NOTIFYMODE> message. The <p lParam> of the
|
|
* message contains the new state of the device (for
|
|
* example, MCI_MODE_STOP). The application can get
|
|
* the text string of the new mode with the <f MCIWndGetMode>.
|
|
*
|
|
* @flag MCIWNDF_NOTIFYPOS | Has MCIWnd notify the parent window
|
|
* when the position of the media changes. MCIWnd sends
|
|
* the <m MCIWNDM_NOTIFYPOS> message to inform the parent
|
|
* window of changes. The <p lParam> of the message
|
|
* contains the new position in the media.
|
|
*
|
|
* @flag MCIWNDF_NOTIFYMEDIA | Has MCIWnd notify the parent window
|
|
* when the media changes. Whenever a file is opened or
|
|
* closed, or a new device is loaded, MCIWnd sends the
|
|
* <m MCIWNDM_NOTIFYMEDIA> message. The <p lParam> of
|
|
* the message contains a pointer to the new filename.
|
|
*
|
|
* @flag MCIWNDF_NOTIFYSIZE | Has MCIWnd notify the parent window
|
|
* when the size of the window changes.
|
|
*
|
|
* @flag MCIWNDF_NOTIFYERROR | Has MCIWnd notify the parent window
|
|
* when an error occurs.
|
|
*
|
|
* @flag MCIWNDF_NOTIFYALL | Notifies parent window of all changes.
|
|
*
|
|
* @flag MCIWNDF_SHOWNAME | Displays the name of the open
|
|
* MCI device element in the window caption.
|
|
*
|
|
* @flag MCIWNDF_SHOWPOS | Displays the position of the MCI device
|
|
* in the window caption.
|
|
*
|
|
* @flag MCIWNDF_SHOWMODE | Displays the mode of the MCI device
|
|
* in the window caption.
|
|
*
|
|
* @flag MCIWNDF_SHOWALL | Displays all window features.
|
|
*
|
|
* @parm LPSTR | szFile | Specifies a zero-terminated string indicating
|
|
* the name of an MCI device or device element to open.
|
|
*
|
|
* @rdesc Returns a handle to an MCIWnd window if successful.
|
|
* Otherwise it returns zero.
|
|
*
|
|
* @comm Use the window handle returned by this function for the
|
|
* window handle in the MCIWnd macros. If your application
|
|
* uses this macro, it does not need to use <f MCIWndRegisterClass>.
|
|
*
|
|
* For non-windowed devices, applications need a window to
|
|
* display the toolbar and trackbar. Applications that
|
|
* access non-windowed devices (such as a waveform audio device),
|
|
* and do not display any controls, can leave the window invisible.
