How does a DCOM component know where to instantiate itself?
Answer / guest
To create a remote instance of a script component, call the
CreateObject method, passing it the name of the remote
computer as a parameter.
If the remotable attribute of a script component's
<registration> element has been set to "true,"
the script component can be instantiated remotely from
another computer using Distributed COM (DCOM).
Both computers must have basic DCOM installed. Note The
ability to use CreateObject for instantiating remote script
components requires Visual Basic 6.0 or later or VBScript
5.0 or later.
The following Visual Basic example shows how to do this on
a computer named "myserver":
Set newS = CreateObject("Component.MyComponent", "myserver")
Note There can be a slight delay when you first
instantiate a remote script component while DCOM
establishes communication between the computers.
1. You can specify the machine on which you want to create
the remote server object in DCOM config ('dcomcnfg').
2. You can specify the machine name when instantiating the
remote server object. In C you can do this with a call to
CoGetClassObject or CoCreateInstanceEx (instead of
CoCreateInstance, which does not allow you to specify the
name of the machine).
In VB you can specify the name in one of the parameters in
the call to CreateObject
