MCI_LOAD
The MCI_LOAD command loads a file. Digital-video and video-overlay devices recognize this
command.
MCIERROR mciSendCommand(MCIDEVICEID wDeviceID, MCI_LOAD,
DWORD dwFlags, (DWORD) (LPMCI_LOAD_PARMS) lpLoad);
Parameters
wDeviceID
Device identifier of the MCI device that is to receive the command message.
dwFlags
MCI_NOTIFY, MCI_WAIT, or, for digital-video devices, MCI_TEST. For information
about these flags, see The Wait, Notify, and Test Flags.
lpLoad
Address of an MCI_LOAD_PARMS structure. (Devices with additional parameters might replace this structure
with a device-specific structure. For digital-video devices, the lpLoad parameter points to an MCI_DGV_LOAD_PARMS structure.)
Return Values
Returns zero if successful or an error otherwise.
Remarks
The following additional flag applies to all devices supporting MCI_LOAD:
MCI_LOAD_FILE
The lpfilename member of the structure identified by lpLoad contains an address of a buffer containing the filename.
The following additional flag is used with the overlay device type:
MCI_OVLY_RECT
The rc member of the structure identified by lpLoad contains a valid display rectangle that identifies the area of the video
buffer to update.
For video-overlay devices, the lpLoad parameter points to an MCI_OVLY_LOAD_PARMS structure.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
