IDelaydC::Start method

The Start method starts a capture.

Syntax

HRESULT STDMETHODCALLTYPE Start(
  [out] char *pFileName
);

Parameters

pFileName [out]

Pointer to the name of the capture file used to store the network data. Be sure to cache this file name if it is needed for future reference.

Return value

If the method is successful, the return value is NMERR_SUCCESS.

If the method is unsuccessful, the return value is one of the following error codes:

Return code Description
NMERR_CAPTURE_PAUSED
The capture is in a paused state and must be stopped before it can be restarted. Call IDelaydC::Stop to stop the capture. For more information, see the Remarks section in this topic.
NMERR_CAPTURING
The capture is already started.
NMERR_NOT_CONNECTED
The NPP is not connected to the network. Call IDelaydC::Connect to connect to the network.
NMERR_NOT_DELAYED
The NPP is connected to the network but not with the IDelaydC::Connect method.

Remarks

The location of the capture file is specified in your Windows registry, but you can use Network Monitor to change the file's location.

To restart the capture by using IDelaydC::Start and IDelaydC::Stop, you must call the IDelaydC::Configure method to reconfigure the connection each time you call the IDelaydC::Start method to restart capturing data. When you start and stop the capture with these three methods, a new capture file is created each time the capture is started.

Note

You can also start and stop the capture by using the IDelaydC::Pause and IDelaydC::Resume methods. When you use these two methods, the captured data is stored in the same capture file.
