These examples pass parameters only as input (by value, or [in]). If we need to pass a parameter that is updatable by the COM method ([in,out]), the code is slightly more complicated. The example C# code that follows uses the DniDataTypes COM component introduced in a prior recipe. It implements a number of methods that use [in,out] parameters, including the following UseLong method. This method is defined in IDL like this: [id(3), helpstring("method UseLong")] HRESULT UseLong([in] long inParam, [in,out] long* outParam); It is implemented like this: STDMETHODIMP CDniDataTypesObj::UseLong(long inParam, long* outParam) { *outParam = inParam; return S_OK; } Here is the C# code needed to call this method with late binding: //Retrieve the Type for the COM object Type comType = Type.GetTypeFromProgID( "DniDataTypes.DniDataTypesObj"); //create an instance of the COM object Object comObj = Activator.CreateInstance(comType); //tell the marshaler that the 2nd parameter is by ref ParameterModifier paramMod = new ParameterModifier(2); paramMod[0] = false; paramMod[1] = true; //in/out ref param //set our array of parameters Object[] args = { 123, 0 }; //show the arguments prior to the call Console.WriteLine( "Arguments prior to COM call - In:{0}, Out:{1}", args[0], args[1]); //execute the COM method Object result = comType.InvokeMember( "UseLong", BindingFlags.InvokeMethod, null, comObj, args, new ParameterModifier[] { paramMod }, null, null); //remember that the in/out param is in the array! Console.WriteLine( "Late-bound in/out method - In:{0}, Out:{1}", args[0], args[1]);

Note We can apply the principle of this optocoupler-based isolation circuit to provide a mains synchronised 50Hz/60Hz reference signal. Figure 16-12 shows the general approach: 12 VAC is provided from a plugpack/wall wart to power the LED in the optocoupler. The external diode means that the optocoupler only sees voltage for one half of the mains cycle and so the transistor will be turned on at 50 or 60Hz depending on the local mains frequency. The external diode is preferred to relying on the LEDs own diode action because it ensures the reverse voltage on the optocoupler isn t exceeded. The plugpack can, of course, be used to power the rest of the circuitry through a suitable bridge rectifier, filter, and regulator.

Cases from customers and others outside of your development group are likely to get into the system via e-mail. Most FogBugz administrators will want to set up one or more mailboxes to receive incoming cases. Figure 2-2 shows a typical case that arrived via e-mail, before anyone from the project team worked on it.

Two recipes cover the use of a new lightweight transactional model that was introduced in the .NET Framework 2.0. It provides an alternative to using ServicedComponent and COM+ when only transaction support is needed. The first of these recipes covers the use of transactional code blocks, while the other demonstrates how to write your own resource manager. The ability to develop a resource manager enables the use of transactions for tasks that traditionally do not use transactions. The final recipe demonstrates the use of services without components. This feature allows you to use COM+ services such as transactions without the need to implement a COM+ component.
