int _tmain(int argc, _TCHAR* argv[]) { CoInitializeEx(NULL, COINIT_APARTMENTTHREADED); //create an instance of the .NET object via COM IPreserveSigPtr comObj(__uuidof(DniNetPreserveSigObj)); if (comObj) { HRESULT hr; CComBSTR result; hr = comObj->CopyString(L"test", &result); _cprintf( "CopyString with string: 0x%8.8x \r\n", hr); hr = comObj->CopyString(L"", &result); _cprintf( "CopyString with empty string: 0x%8.8x \r\n", hr); hr = comObj->CopyStringPreserve(L"test", &result); _cprintf( "CopyStringPreserve with string: 0x%8.8x \r\n", hr); hr = comObj->CopyStringPreserve(L"", &result); _cprintf( "CopyStringPreserve with empty string: 0x%8.8x \r\n", hr); comObj.Release(); } CoUninitialize(); return 0; } The code calls each of the methods twice: first with a valid string and then with a zero-length string. The second call to each method should produce an HRESULT of S_FALSE (1). However, from what we have learned, it is unlikely that the CopyString method will return anything other than zero. When we execute the code, we see these results: CopyString with string: 0x00000000 CopyString with empty string: 0x00000000 CopyStringPreserve with string: 0x00000000 CopyStringPreserve with empty string: 0x00000001

Figure 15-11. USB/OBD-II PCB modified with surface-mount LEDs and with power and serial connections in place Figure 15-11 shows an ELM327-based adapter that has had the original LEDs replaced with surfacemount LEDs, and the serial cable connected to ground, TX, and RX, with the VCC lead left unconnected at the ELM end. The VCC lead is connected in the socket, but is cut short and left unconnected at the other end. You can also see the 4-pin male header fitted to the USB lead pads on the bottom left corner of the board so a USB cable can be reconnected to use the adapter as it was originally designed. Power from the car to the Arduino is going to be taken from the OBD-II connection as well, so fit a short length of hookup wire to an oriented 2-pin female header and connect the other end to the GND and +12V pads on the PCB back of the OBD-II header. You can t see it in the photo in Figure 15-11, but the pair of wires connect to the back of the 8-way header, with 0V on the left end and +12V on the right. Unless your OBD-II adapter happens to be exactly the same as ours, you ll need to check out the connections with a multimeter to figure out which is which, but it should also be fairly easy to determine by following through the pin assignments from the OBD-II plug back through to the adapter.

As expected, CopyString always returns S_OK (zero). Even when the code attempts to throw an exception for a value of 1, the success HRESULT is thrown away. However, the CopyStringPreserve method does successfully return either S_OK or S_FALSE.

Also shown in Figure 15-11 is an 8-way female header connected to a DB9 panel-mount socket for connecting to the OBD-II cable. If your OBD-II adapter has a different type of connection, you might have to alter the design accordingly.
