MCI_SYSINFO
The MCI_SYSINFO command retrieves information about MCI devices. MCI supports this command
directly rather than passing it to the device. Any MCI application can use this
command. String information is returned in the application-supplied buffer
pointed to by the lpstrReturn member of the structure identified by lpSysInfo. Numeric information is returned as a doubleword value placed in the
application-supplied buffer. The dwRetSize member specifies the buffer length.
MCIERROR mciSendCommand(MCIDEVICEID wDeviceID, MCI_SYSINFO,
DWORD dwFlags, (DWORD) (LPMCI_SYSINFO_PARMS) lpSysInfo);
Parameters
wDeviceID
Device identifier of the MCI device that is to receive the command message.
dwFlags
One or more of the following standard and command-specific flags:
MCI_SYSINFO_INSTALLNAME
Obtains the name (listed in the registry or the SYSTEM.INI file) used to
install the device.
MCI_SYSINFO_NAME
Obtains a device name corresponding to the device number specified in the dwNumber member of the structure identified by lpSysInfo. If the MCI_SYSINFO_OPEN flag is set, MCI returns the names of open devices.
MCI_SYSINFO_OPEN
Obtains the quantity or name of open devices.
MCI_SYSINFO_QUANTITY
Obtains the number of devices of the specified type that are listed in the
registry or the [mci] section of the SYSTEM.INI file. If the MCI_SYSINFO_OPEN flag
is set, the number of open devices is returned.
lpSysInfo
Address of an MCI_SYSINFO_PARMS structure.
Return Values
Returns zero if successful or an error otherwise.
Remarks
The wDeviceType member of the structure identified by lpSysInfo is used to indicate the device type of the query. If the wDeviceID parameter is set to MCI_ALL_DEVICE_ID, it overrides the value of wDeviceType. For a list of device types, see Constants: Device Types.
Integer return values are doubleword values returned in the buffer pointed to
by the lpstrReturn member of the structure identified by lpSysInfo.
String return values are null-terminated strings returned in the buffer
pointed to by the lpstrReturn member of the structure identified by lpSysInfo.

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 » |
