Parameters of type System.Object are exposed to COM clients as Variants. This makes sense since a System.Object can represent any .NET data type, just as a Variant does for COM. The generated typelib will use a VARIANT for any System.Object parameters or return values. For example, this C# method uses and returns a System.Object: Object MyObjectMethod(Object param); Here is the same method defined in Visual Basic .NET (VB.NET): Function MyObjectMethod(ByVal param As Object) As Object Regardless of the language, when exported to a typelib for use by COM, the method is defined like this: HRESULT MyObjectMethod( [in] VARIANT param, [out, retval] VARIANT* pRetVal); Variants include a Variant Type (VT_*) that identifies the underlying data type. The interop marshaler automatically sets the Variant Type for you based on the actual data type that is used. For example, a managed method may return a System.Object as the result value. This means the method can potentially return any data type. When the result value is marshaled back to the COM client code, the actual data type is used to set the Variant Type. If the method returns a System.Int32, then the Variant Type is set to VT_I4 (32-bit signed integer). If the method returns a System.String, the Variant Type is set to VT_BSTR. And so on. When data flows in the other direction, the marshaler has to pass data of the correct type as the System.Object parameter. If the COM client passes a Variant with a Variant Type of VT_DATE, then the managed code will see a System.DateTime value passed as the System.Object parameter. If a VT_BSTR is passed, then a System.String is provided by the marshaler. This marshaling behavior is automatic and in most cases produces exactly the results that you want.

In this chapter, you learned about the integration between FogBugz and various source code control applications. You saw how to set up the integration and were introduced to some scenarios where it s very helpful to have this in place. With that, you know almost all of the ins and outs of FogBugz: you ve gone from simply entering cases, through managing and administering the system, to using it in conjunction with your other programming tools. There s one final key point to remember, though. Because FogBugz is supplied as ASP or PHP pages as well as an unlocked database, its source code is completely open. Though Fog Creek doesn t officially support users modifying their own installations, there s nothing to prevent you from making changes if you find something that doesn t quite work the way you d like. I urge you to learn the system inside and out before you start tweaking, though. But if you do need to stretch the boundaries of FogBugz, open the pages in your favorite editor and you may find that the changes you need are easy to make.

code. While 5 covers use of COM components from managed code, much of the material is also applicable when you are exposing managed code to COM clients.

This C# code illustrates the marshaling that takes place when passing Variants to managed methods. We start by implementing an interface and managed class: using System; using System.Runtime.InteropServices; namespace DniNetVariants { public interface IVariants { string UseVariant(Object inParam, ref Object outParam); } [ClassInterface(ClassInterfaceType.None)] public class DniNetVariantsObj : IVariants { public string UseVariant(object inParam, ref object outParam) { //copy the input param to the output outParam = inParam; //return the type description return inParam.GetType().Name; } } } Here is the same class and interface implemented in VB.NET: Imports System.Runtime.InteropServices Public Interface IVariants Function UseVariant(ByVal inParam As Object, _ ByRef outParam As Object) As String End Interface <ClassInterface(ClassInterfaceType.None)> _ Public Class DniNetVariantsObj Implements IVariants
