IScanningTunerEx::ResumeCurrentScan method (tuner.h)
[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]
This topic applies to Windows Vista and later.
The ResumeCurrentScan method resumes scanning the range of frequencies specified in PerformExhaustiveScan.
Syntax
HRESULT ResumeCurrentScan(
[in] HEVENT hEvent
);
Parameters
[in] hEvent
Handle to an event created by the application. When the tuner locks onto a signal, it signals this event.
Return value
Returns an HRESULT value. Possible values include the following.
| Return value | Description |
|---|---|
|
No scan has been started yet. |
|
Invalid hEvent argument. |
|
Success. |
When the method succeeds, it returns S_OK. Otherwise it returns an HRESULT error code.
Remarks
When the application calls PerformExhaustiveScan, the tuner scans until it locks onto a signal. Then it sets the application's event handle. To resume scanning for the next valid signal in original range of frequencies, the application can call ResumeCurrentScan.
