COM interop doesn t provide a direct way to return a success HRESULT to a COM client. When managed code throws an exception, an error HRESULT is returned to the caller. The same does not hold true for success HRESULT codes such as S_FALSE or a custom success HRESULT. Success HRESULT values are simply thrown away when a managed method returns. And there is no direct mechanism to even set an HRESULT from managed code. However, using the PreserveSig attribute, you can pass multiple success HRESULT values to the calling code. This attribute can be found in the System.Runtime.InteropServices namespace. Without this attribute, the default behavior is to transform all managed methods to return an HRESULT and to not preserve the original method signature. For instance, consider this managed method: string MyMethod(int paramA);

When exported to a COM typelib, this method will be defined like this: HRESULT MyMethod([in] long paramA, [out, retval] BSTR* pRetVal); The result string is turned into an [out,retval] and the actual return value is an HRESULT This is a very typical signature for a COM method We can apply the PreserveSig attribute to the method like this: [PreserveSig] string MyMethod(int paramA); When the method is exported to a typelib, it is defined like this, preserving the original method signature: BSTR* MyMethod([in] long paramA); Now that you know what the PreserveSig attribute does, how does it help you return an HRESULT Instead of allowing the marshaler to provide an HRESULT, you can define a method that explicitly returns an HRESULT If you add PreserveSig to the method, the signature of the method will not be transformed You can then return an HRESULT using the method as you have defined it.

Figure 15-8. Gaining access to TX and RX pins by bending LEDs On the other adapter, we removed the original LEDs entirely and soldered tiny surface-mount LEDs in 0805 (2mm 1.25mm) packages directly to the pads on the PCB. The result is a very slick, lowprofile board. If you don t have access to surface-mount LEDs, you could simply resolder the existing 3mm LEDs flush down on the board without the plastic spacers. Because the FTDI chip provides a high-impedance connection to the ELM327, you might not need to disconnect it. On one of our adapters, we left the connections in place and soldered jumper wires directly to pins 17 and 18 of the ELM327, and it worked fine. Leaving the connection in place allows you to reconnect the USB cable and use the adapter with your laptop again as described previously. Breaking the TX and RX connections between the ELM327 and the FTDI chip will prevent you from using the adapter again via USB, but might be necessary depending on the model of adapter. If you need to disconnect pins 17 and 18, you can use a sharp scriber to lever up each pin while simultaneously melting the solder with a very fine soldering iron tip, as shown in Figure 15-9.

You will be in control and the marshaler will not attempt to set the HRESULT automatically for you To demonstrate this, consider this interface implemented in C#: public interface IPreserveSig { void CopyString(string inParam, ref string outParam); [PreserveSig] [return: MarshalAs(UnmanagedTypeError)] int CopyStringPreserve(string inParam, ref string outParam); } The CopyString method uses the default marshaling It accepts a string as the first parameter and a string passed by reference as the second It doesn t have a return value that we have defined The CopyStringPreserve method is defined the same way except that it returns an integer It also has two attributes, PreserveSig and MarshalAs The MarshalAs attribute is applied to the return value (the integer) and forces it to be marshaled as UnmanagedTypeError This means it will be marshaled as an HRESULT.
