If the managed code attempts to read from another directory, a SecurityException will be thrown Likewise, if we attempt to write to a file (instead of reading it) in the proper directory, an exception is thrown If the managed code attempts anything else such as accessing the registry, opening a socket connection, or reading environment variables an exception is thrown With these few lines, we have already restricted much of what the managed code is allowed to do Now that our operational boundaries have been set using code access security, we can execute a series of checks in managed code prior to calling the unmanaged function The wrapper now performs several validation tasks Starting with basic validation of input parameters, it verifies the presence of the file path input parameter.

Figure 6-5. Double End-Of-Line resistors connected to an analog input Looking only at the right half of the circuit for now, you can see that the resistance across the sensor output wires can be one of the four different values shown in Table 6-1. Table 6-1 Sensor resistance in various states

This is the type of simple validation that we would rather handle here in managed code instead of blindly passing parameters to the unmanaged function The individual parts of the full file path are now validated, checking the existence of the directory and the requested file In this sample code, we assume that the file already exists prior to calling the function That may not be a realistic assumption, but it works well enough for demonstration purposes During validation, we throw a custom FileProcessException object if any errors are detected This simplifies any calling code, allowing it to catch a single exception regardless of the type of validation error encountered If the input parameters appear to be in order, we finally make the call to the unmanaged function Since the memory for the returned string is allocated in unmanaged code, we marshal the returned pointer as an IntPtr.

Wire shorted. Alarm to be activated unless in maintenance mode. Normal. Sensor tripped. Alarm to be activated if armed. Wire cut or tamper detected. Alarm to be activated unless in maintenance mode.

This allows us to marshal the result to a String ourselves and later free the memory In order to free the memory, we call the FreeUnmanagedString function, passing it the IntPtr that we received from the original function Notice that we do this within a finally block In the event an exception is thrown, we want to be assured that memory was properly freed..

Note You ll see in Figure 3-4 that one of the projects has a note indicating that it s an Inbox. Only e-mail enabled projects will have such a note, and you can t edit these notes yourself through the FogBugz user interface. See 5 for more information on e-mail enabling a FogBugz project.
