LookupItemDetailBlit results: 111,9988,10012002,5.49 One final point. We saw earlier that a class (a reference type) is seen by unmanaged code as a pointer or C++ reference to a structure when it is marshaled as a formatted class. If we pass an instance of a formatted class by reference, how is that used in unmanaged code It is seen as a pointer to a pointer. Consider this revised C# code that now passes a class by reference: [DllImport("FlatAPIStructLib.DLL")] public static extern bool LookupItemDetailByRef( ref ManagedItem item); //pass a class instance by ref ManagedItem item = new ManagedItem(); item.ItemId = 111; //call the unmanaged function passing the class by ref result = LookupItemDetailByRef(ref item); //show the results Console.WriteLine( "LookupItemDetailByRef results: {0},{1},{2},{3},{4}", item.ItemId, item.ItemDesc, item.TaxCategoryId, item.CategoryCode, item.UnitPrice);

Those four IDs correspond to temperature, humidity, rainfall, and wind sensors, respectively To extract the sensor ID we grab the appropriate byte from the message packet, then apply a shiftright operator and apply a logical AND to mask out the rest of the byte that we don t care about b = bICP_WSR_PacketData[bICP_WSR_PacketOutputPointer][5]; b = (b >> 4) & 0x03; Then it s a simple matter of checking the value of the sensor ID and processing the rest of the message to suit the requirements of that particular sensor Sensor ID 0 is the temperature sensor which puts the first temperature digit in the lower nibble of byte 7 We extract that and multiply it by 100 because it s in the hundreds column, then put the value into the si variable.

Note When passing a class instance by reference, you are not required to add the In and Out attributes.

We then move on to processing the additional temperature digits in the upper and lower nibbles of byte 8, multiplying the tens digit by 10 and simply adding the ones digit as is switch( b ) { case 0: { si = ((bICP_WSR_PacketData[bICP_WSR_PacketOutputPointer][7] & 0x0F) * 100); si += ((bICP_WSR_PacketData[bICP_WSR_PacketOutputPointer][8] >> 4) * 10); si += (bICP_WSR_PacketData[bICP_WSR_PacketOutputPointer][8] & 0x0F); At this point we re very close to having the value we need, but because the value that is sent through is an unsigned number it can t represent negative values and it also doesn t have a decimal point Not much good if the temperature drops below 0 The number sent through is, therefore, multiplied by 10 to.

In order to use the class instance passed by reference, the function needs to be rewritten like this: bool LookupItemDetailByRef(UnmanagedItemStruct** ppItemStruct) { if (ppItemStruct == NULL) { return false; } //lookup item and fill the struct (*ppItemStruct)->CategoryCode = 10012002; (*ppItemStruct)->TaxCategoryId = 9988; (*ppItemStruct)->UnitPrice = 5.49; (*ppItemStruct)->ItemDesc = (char*)CoTaskMemAlloc(255); strcpy_s((*ppItemStruct)->ItemDesc, 255, "item description"); return true; }

FogBugz has an internal notion of when your team should be at work. This working schedule is used for two purposes. First, it calculates an automatic due date for incoming e-mail, based on the e-mail policies you ve set up. Suppose, for example, your policy is to respond to all e-mail within 12 hours. If an e-mail comes in at 3 p.m. Friday, and you only work 9 a.m. until 6 p.m. on weekdays, and not at all on weekends, FogBugz is smart enough to set the due date to 9 a.m. on Tuesday. The second use for the working schedule is to convert between hours and days when storing estimates for a case. Administrators can customize the working schedule to fit their company s needs. To do so, log on as an administrator and click the Site link in the Administrative Tools bar. Scroll down on the site configuration page and click the Working Schedule link to open the Working Schedule screen, shown in Figure 3-17.

remove the decimal place and then offset by 300 above the actual value, so to determine the real value we subtract 300 from whatever value the sensor reported and then divide by 10 siWSR_CurrentTemperature = (si - 300); The value is then printed to the host via the serial port, but even this requires a little trick because after we ve divided the number by 10 it will become a decimal value and can t be passed directly to Serialprint Therefore we print the divided value which will print just the part before the decimal point, then manually send a period, then send the modulus of the temperature to get just the decimal part Serialprint("TEMPERATURE="); Serialprint( (siWSR_CurrentTemperature/10), DEC ); Serialprint( '', BYTE ); if( siWSR_CurrentTemperature < 0 ) { Serialprintln( ((0-siWSR_CurrentTemperature)%10), DEC ); } else { Serial.

While this code isn t as straightforward as the prior examples, it does work. When you see that a function expects a pointer to a pointer to a struct (or class), you should be prepared to pass a class by reference.
