LINEDEVSTATUSFLAGS_ Constants
The LINEDEVSTATUSFLAGS_ bit-flag constants describe a collection of Boolean
line device status items.
LINEDEVSTATUSFLAGS_CONNECTED
Specifies whether the line is connected to TAPI. If TRUE, the line is
connected and TAPI is able to operate on the line device. If FALSE, the line is
disconnected and the application is unable to control the line device through TAPI.
LINEDEVSTATUSFLAGS_MSGWAIT
Indicates whether the line has a message waiting. If TRUE, a message is
waiting; if FALSE, no message is waiting.
LINEDEVSTATUSFLAGS_INSERVICE
Indicates whether the line is in service. If TRUE, the line is in service; if
FALSE, the line is out of service.
LINEDEVSTATUSFLAGS_LOCKED
Indicates whether the line is locked or unlocked. This bit is most often used
with line devices associated with cellular phones. Many cellular phones have a
security mechanism that requires the entry of a password to enable the phone to
place calls. This bit may be used to indicate to applications that the phone
is locked and cannot place calls until the password is entered on the user
interface of the phone so that the application can present an appropriate alert to
the user.
No extensibility. All 32 bits are reserved.
LINEDEVSTATUSFLAGS_ constants are used within the dwDevStatusFlags field of the LINEDEVSTATUS data 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 » |
