Listing 5-19 shows the full contents of our Execute method. As before, line numbers are included for reference only. Here s a rundown of what happens in the method: Lines 3 and 4 set some values so that we can keep track of the process of our activity. Running is the property we created earlier. ActivityStarted is a local variable used to flag that our activity has started a child activity running. We ll use it at the end to determine what value to return. Line 5 checks the Condition property we set up by calling its Evaluate method. If the condition set by the workflow builder indicates we should do some logging, we ll continue on with lines 6 through 16. Otherwise, we jump right to line 18 and begin executing our child activities. Lines 7 16 loop through our child activities looking for the logging activity, which we actually add in the ToolboxItem class in just a few minutes. In the ToolboxItem class we will set a value in the UserData property so we could identify our activity here. Line 18 begins a loop through the child activities of our composite activity that have their Enabled property set to true. This loop ends on line 27. Line 23 is where we set things up to be able to catch the event fired off when our child activity finishes executing. We make use of the generic RegisterForStatusChange method and pass in a parameter that specifies what event it is that we are looking for Activity.ClosedEvent.

Figure 6-4. Workflow designer It is even possible to host the workflow designer within your application.

In Figure 13-2, EL is the value of _editLevel in the collection, ELA is the _editLevelAdded value in each child object, and DEL is the IsDeleted value in each child object.

It is also possible to explicitly grant other assemblies access to all private types. This is usually done in unit testing scenarios. The InternalsVisibleToAttribute from the namespace System::Runtime::CompilerServices can be used to specify friend assemblies as shown here:

Using this approach, you need to pick a starting value for the normal. If you make sure your track starts out flat, you can simply use the (0,1,0) Up vector as the starting normal, so define this line before your for loop: Vector3 currentNormal = Vector3.Up; For each point of the track, you should adjust this vector to take the curving of the track into account. The curving can be expressed by the centrifugal direction: it s the direction you need to pull the car so it isn t flying out of the corners of your track, and it s shown in Figure 5-38.
