Time
Limit
You can limit
the duration of a capture operation by using the fLimitEnabled and wTimeLimit
members of the CAPTUREPARMS
structure. The fLimitEnabled member indicates whether the capture
operation is to be timed, while wTimeLimit specifies the maximum
duration of the capture operation.
You can
retrieve the values for fLimitEnabled and wTimeLimit by using the
WM_CAP_GET_SEQUENCE_SETUP
message (or the capCaptureGetSetup macro). You can enable a timer for the capture
operation by specifying TRUE as the value of fLimitEnabled, or you can
set the duration of the capture operation by specifying a value, in seconds,
for wTimeLimit. After you set these members, send the updated CAPTUREPARMS structure to the capture
window by using the WM_CAP_SET_SEQUENCE_SETUP message (or the capCaptureSetSetup macro). The default value
of fLimitEnabled is FALSE.
