license keys along with the CLSID values using the DumpClassData utility mentioned earlier in this chapter The license strings are available only for controls that have a design-time license on the current machine Since you don't use New or CreateObject to load a custom control, you can't use the functions from COMDlILoaderbas functions to directly load a COM control the way you would an object from a DLL You need to let VB create a control for you, and then redirect all requests to the VB-created control to a control object you've custom loaded from an OCX Making an object appear to be another object is easy with the VBoost objects, but there are some drawbacks to this technique that I need to mention before I show you the code You have to decide if it is worth trading these limitations for the DLL heaven and code-reuse advantages that custom DLL-loading provides Custom OCX loading doesn't let you use the property sheet to set native control properties However, all the extender properties and property pages are fully accessible Also, any properties you set at design time are written correctly to the containing Frm, Ctl (UserControl), or Dob (UserDocument) files and are reflected when the control is instantiated at runtime See "VTable Binding Custom Control Interfaces" in 4 for more information on native and extender properties of custom controls Custom OCX loading doesn't allow you to receive native control events directly through the control variable Instead, you must receive extender events (GotFocus, and so on) through the normal mechanism and use a separate WithEvents variable to get the native events You must block support for the IQuickActivate interface, which increases the performance of loading custom controls IQuickActivate fails to reconcile the event interface it expects with the one that the custom-loaded control actually supports If you can accept these limitations, you can custom load OCX files just like DLLs You simply need to know the OCX's location (relative to the application path) and the CLSID of the control To dynamically load the control, add a new UserControl to your project and run the following code for every control you.

As you can see, there are multiple steps that IT personnel need to take to protect their BlackBerrys from malware. This includes keeping the BlackBerry infrastructure up-to-date and configured securely, protecting the endpoint BlackBerry device with antivirus/antimalware software, and keeping abreast of vulnerabilities and exploits to the devices and their supporting infrastructure.

MyActivator activator; PortableServer::ServantManager_var servant_manager = &activator; servant_manager_poa->set_servant_manager (servant_manager);

At this point, an object reference to the as-yet inactive remote object is created with a user-defined OBJECT ID, which allows us to identify requests for a specific servant.

There are several additional typelibs that carry the VBoost name to make them easy to find in the Project/References dialog These typelibs also use types from the main type library to eliminate redefinition of common types These files include VBoost: Object Creation and Security (ObjCreateOlb), VBoost: Ole Type Definitions (OleTypesOlb), VBoost: Type Library Types and Interfaces (TlbTypesOlb), VBoost: API declares used for threading (ThreadAPlOlb), and VBoost: ROT Hook Types (ROTHookTypesOlb) VBoost itself does not require references to the additional libraries You'll need to initialize a VBoost variable before running the samples in this book This is easily done with the following steps: Use the Project/References dialog to add a reference to VBoost Object Types (60) and VBoost Object Implementation (60) Add the VBoostBas file from your local copy of the PowerVB\Code directory on the book's CD Call InitVBoost somewhere early in your code It is easiest to do this from Sub Main, but there is minimal penalty for calling InitVBoost more than once just to be sure You are now ready to pull any of the files from the PowerVB\Code directory and write your own code against the VBoost extensions

Direct attacks are always very dangerous. The reason they are so devastating is that a hacker is making conscious decisions on how to exploit the device, while actively connected to the device. It s quite simple to see why that is a problem. There are two ways main mobile devices are susceptible to direct attacks:

PortableServer::ObjectId_var object_id = PortableServer::string_to_ObjectId ("Foo"); CORBA::Object_var object = servant_manager_poa->create_reference_with_id (object_id, "IDL:Foo:1.0");

A hacker finds their IP addresses and attempts to run exploits directly against them Malware, such as a Trojan, is somehow loaded onto the device, which gives a hacker direct remote control access over the device.
