A client-propagated model. The client thread s priority gets sent to the server using the INVOCATION CONTEXT, as illustrated in the figure below.

Allow Allows third-party applications to establish the connection any time they want to Deny Denies third-party applications from establishing connections Prompt Prompts the end user, asking if the connection attempt is allowed Custom Allows different settings for different programs; that is, some programs could be denied, while others may be allowed or generate a prompt

.

A server-declared model. The priority is set in the POA and sent to clients as part of the ABSOLUTE OBJECT REFERENCE. The following figure illustrates this.

always passed nevertheless To get the memory address of the object (which you need only when it is time to free the memory), simply call VarPtr(This) or the equivalent VarPtr(ThispVTable) In the CreateLightEmpty function, a LightEmpty structure is filled and then copied into an allocated memory location The point of transfer seems pretty complicated Your first attempt might involve just coding the copy with a simple CopyMemory call CopyMemory ByVal ThisPtr, Struct, LenB(Struct) There are two problems with this code when you apply it to an arbitrary structure These problems don't exist with the LightEmpty structure because it isn't complex enough, but you must watch out for them in general The first problem occurs if Struct contains string parameters If you use a CopyMemory API call declared in VB, any string parameters undergo UNICODE/ANSI translation during the API call You can prevent string translation by replacing Struct with ByVal VarPtr(Struct) In the case of a lightweight object, however, the first element of the structure is a Long, which doesn't undergo translation during an API call Combine the lack of translation on a Long with the fact that VarPtr(Struct) and VarPtr(Struct<FirstMember>) are always equivalent, and you see that ByVal VarPtr(Struct) is equivalent to ByRef StructpVTable Of course, if the CopyMemory is typelib declared, such as the VBoostTypes-declared CopyMemory function, you won't have this potential problem, but the code shown in the listing is always safe The second problem with the single CopyMemory call is that VB thinks the data in Struct needs to be freed when the function goes out of scope VB has no way of knowing that ownership of the structure has moved elsewhere If the structure contains object or variable-size String or array types, VB will kindly free them for you when the object goes out of scope But you are still using the structure, so this is an unwanted favor To prevent VB from freeing referenced memory in the stack object, simply ZeroMemory the structure When you apply the CopyMemory call's ANSI/UNICODE precautions to ZeroMemory, you get the transfer code seen in the listing There is an additional memory problem to watch out for In this situation, you are responsible for explicitly freeing pointer-type members in the structure.

In the following code example we register a CORBA object with the POA for the client-propagated model. Operations are invoked with the
