Selecting a NIC Using GetNPPBlobFromUI

  • Article

With Network Monitor, selecting a NIC programmatically is a two-step process. First, create the filter BLOB by calling the CreateBlob method. Then, select the NIC by calling the GetNPPBlobFromUI method.

In this example a filter BLOB is used to select the required NIC:

DWORD rc;

// Call CreateBlob to create a filter blob.
///////////////////////////////////////////
HBLOB hFilterBlob;
rc = CreateBlob(&hFilterBlob);
if (FAILED (rc));
{
  // Failed creating filter BLOB. Add appropriate error handling.
}


// Call GetNPPBlobFromUI to retrieve the NPP Blob.
//////////////////////////////////////////////////
rc = GetNPPBlobFromUI(hwnd,
                      hFilterBlob,
                      &hBlob);
if (FAILED (rc));
{
  // Failed retrieving NPP BLOB. Add appropriate error handling.
}
