VGSecurityManagerSetSecurity Method (Object)

public static void SetSecurity(
	Object target
)

Public Shared Sub SetSecurity ( 
	target As Object

You need to call this method only once for each object instance.In most of case, this method must be called at the end of constructor of the object (after the call of InitializeComponent method for components). This method registers the object in Visual Guard then it executes the actions defined for this target to be executed when the security is loaded.If some actions must be executed on other events, It handles these events. The actions associated to these events will be executed each time the events are raised.
