By default, parameters of type System.String are marshaled as a COM BSTR. This makes perfect sense since the BSTR is a core type that was specifically designed for use within COM applications. The System.String and BSTR types both also use Unicode to internally represent strings. Because of this, most COM components use a BSTR for strings. Therefore, most of the time you can use the default behavior and allow your System.String parameters to be marshaled as a BSTR. When a typelib is generated, the COM directional attributes will change depending on how the string is passed to the method. For instance, a string may be passed to a method by value like this: void ReadOnlyString(string myString); In this case, the string parameter will be marshaled as an [in]BSTR like this: HRESULT ReadOnlyString([in] BSTR myString); On the other hand, a string can be passed by reference to a method like this: void RefString(ref string myString); For this method, the string will be passed as an [in,out]BSTR* like this: HRESULT RefString([in,out] BSTR* myString); Strings returned from a method like this: string ReturnAString();

Having a very large capacitor on the input of the voltage regulator provides enough reserve power to keep the voltage regulator running at its rated voltage for a few extra milliseconds after power is disconnected from the input By having the CPU detect input failure through the voltage divider, it can use that time to quickly put its house in order before the power drops out entirely Tasks it might need to do in that time include closing any files that are open on the USB memory stick, because if the power fails while a file is open it probably won t be written properly and could end up corrupted or even entirely empty with all your logged data gone forever Fit the LM2940CT-5 to the prototyping shield, with the common (center) pin connected to ground on the shield and the output (right) pin connected to +5V.

are marshaled as an [out,retval]BSTR* like this: HRESULT ReturnAString([out,retval] BSTR* pRetVal); Optionally, you can modify how strings are marshaled by applying the MarshalAs attribute. This attribute can be applied to individual parameters or to the return value for a method. For example, this method accepts a string passed as a LPWSTR (a pointer to a Unicode character array) instead of a BSTR: void UseRawString([MarshalAs(UnmanagedType.LPWStr)] string myString); This method returns a string as a LPWSTR: [return:MarshalAs(UnmanagedType.LPWStr)]string ReturnRawString();

The Mega prototyping shield from NKC Electronics we used in our prototypes has handy ground and 5V rails beside each other down the center of the board, so the voltage regulator can be fitted straight across them with two of the pins on the two supply rails The input (left) pin will eventually be connected to the car s +12V supply line via the OBD adapter If the pins of the voltage regulator are just a little too big to fit comfortably through the holes in the prototyping shield, you can cut them off to about half length and very carefully trim a fraction off the thickness of each leg with wire cutters or a small file.

Caution Be careful when using the MarshalAs attribute. It is possible to return strings in a format that is
