In the Writing Components topic of Mr. Grimes' book on Managed C++, he
states that if a component is ultimately derived from either
MarshalByRefObject or MarshalByValueComponent, it should implement a second
constructor which takes an IContainer in order to add itself to a component
container. I have a few questions regarding this:
1) What container creates a component calling this second constructor ?
2) Why does MarshalByRefObject or...

Hi all,
At a high level here is what is going on -- I built a C# COM object. I need to call this com object from SQL Server using the sp_OACreate stored procedure in SQL Server. I build the COM object, register it using regasm, but when I try to call it in SQL Server I get the following error message - "0x80070002 Extended Procedure The system cannot find the file specified."

Hi, i have a problem. I try to create a non visual component. This is
a simple component that makes database connection. I use the following
code. But in design time i can't see the properties. I use public
properties. Everything seems ok but in design time i can not see the
properties that i have defined. I defined server name,database name,

Hello,
I have a fairly simple class that I created and it works great. Basically
it remembers a certain amount of strings. When a new one comes in the oldest
drops off. The problem is, when I have the test page open in multiple
browsers, they are all getting the same data. I don't want this to happen.
I have tried different uses of protected, internal, static and such with no
luck. Can anyone help me here?

I make a similar post in another newsgroup, but this example is
simplified somewhat.
I have a component (cmpMyComponent) with 2 properties. The 1st property
is a string value (Description) and the 2nd property is a strongly typed
collection class (myCollectionProperty).
The collection contains a simple class (myCustomClass) which has 1 text
property (TextProperty).

Hello everyone,
I have created a custom component and one of its properties is a class
object with it's own properties. During runtime, I can assign values to the
class object properties just fine. However, when attempting to assing
default values as designtime in the propertygrid, nothing is working on the
class object. I know that I am doing it wrong, any ideas what it is?
Thanks in advance

The definition of a component model I use below is a class which allows
properties, methods, and events in a structured way which can be
recognized, usually through some form of introspection outside of that
class. This structured way allows visual tools to host components, and
allows programmers to build applications and libraries visually in a RAD
environment.
The Java language has JavaBeans as its component model which allows Java...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
