Figure 6-2. Schematic for security sensor inputs EOL resistors can also be used with normally open (N.O.) sensors simply by putting the resistor in parallel with the sensor output instead of in series with it (see Figure 6-4). In this scenario the line will go into a low-resistance state if the sensor is triggered, but otherwise operates in a similar way to an N.C. sensor.

String.Format( _ "File {0} does not exist", filePath), _ Nothing) End If Try 'call the unmanaged function stringPtr = ProcessTestFile(filePath) If Not stringPtr = IntPtr.Zero Then 'marshal the returned pointer to a string result = Marshal.PtrToStringAnsi(stringPtr) End If Finally If Not stringPtr = IntPtr.Zero Then 'free the memory from unmanaged code FreeUnmanagedString(stringPtr) End If End Try Return result End Function End Class End Module This code implements a number of security-related features. Starting with the class declaration for FileProcessWrapper, we have declared the class in C# using the internal access modifier: internal class FileProcessWrapper This access modifier restricts the use of this class to the current assembly only. Managed classes that are packaged in other assemblies are prohibited from referencing this class. This is a simple way to limit the access to the unmanaged function, since we presumably trust the other code in the same assembly. While this works in the example code, it obviously would cause issues if you were developing a library of managed code that was to be used by multiple applications. After declaring the unmanaged functions that the code will call, we reach the heart of the wrapper, the static ProcessFile method. The first task in this method is to establish our requirements for code access security using this code: //set up permissions that we need PermissionSet pSet = new PermissionSet(PermissionState.None); //restrict IO to only a single known directory pSet.AddPermission(new FileIOPermission( FileIOPermissionAccess.Read | FileIOPermissionAccess.PathDiscovery, @"c:\InteropTest")); //add permission to execute unmanaged code pSet.AddPermission(new SecurityPermission(

Tip Don t make the mistake of thinking that projects absolutely must map directly to products. If your requirements are unusual, it may make more sense to brainstorm an alternative arrangement. For example, if your primary business is customizing an off-the-shelf product for a vertical market, and you assign customization to representatives around the country, you may want to set up one project for each geographical region.
