This next example also uses the AddSomeNumbers function, making a different type of mistake when it is declared: //incorrect type of parameters [DllImport("FlatAPILib.DLL" ,CharSet=CharSet.Unicode)] public static extern int AddSomeNumbers(char charOne, int numTwo); Here, we ve declared the first parameter as a char rather than an integer. We run the test with this code: //incorrect parameter type try { //this doesn't throw an exception. Instead, it uses the //unicode value of an 'A' (65) as an integer. int result = ErrorAndExceptionTest.AddSomeNumbers('A', 100); Console.WriteLine("Result from AddSomeNumbers = {0}", result); } catch(Exception e) { Console.WriteLine("Exception from AddSomeNumbers: {0}", e.Message); } If you expected to see the same EntryPointNotFoundException, you might be surprised with the result. As the code comments indicate, this test doesn t throw any exception at all. Instead, the interop marshaler is able to make the most of what we ve declared and find the matching function. How is it able to do this Remember that the char that we ve declared is actually a Unicode char (16-bit). PInvoke is able to pass the char to the unmanaged function as an integer. The result is that the unmanaged function adds the decimal value for the character 'A' (65) to the other number we passed as a parameter (100), and returns a value of 165: Result from AddSomeNumbers = 165 Not all mistakes end up as exceptions. More often than not, they end up as puzzling, incorrect results that require some investigation. In this case, it would have been easier to detect and correct the problem if we had received an exception.

lcd_gotoXY(clearStart,row); for (byte cleanup = clearStart; cleanup < clearEnd; cleanup++) { lcd_dataWrite(' '); } } For maintenance purposes, one of the most important pieces of information available via OBD-II is the response to mode 0x03, Show diagnostic trouble codes It s also one of the most complex because of the variations in the type of data that it needs to return Mode 0x03 doesn t contain any PIDs, so there s no need to request anything but the mode itself, and it always returns four bytes of data A typical response could be as follows: 43 17 71 00 00 00 00 The 43 header is because it s a response to a mode 0x03 request, and response headers always start with the mode plus 0x40 The rest of the message is three pairs of bytes, so this example would be read as 1771, 0000, and 0000.
