Script to list non-Microsoft Services - windows-services

Been lookin' for a way to list the non-Microsoft Services to a *.txt file.
Either using vbs or a batch file will be sufficient.
I've tried numerous ways with WMI and the sc.exe command, but can't seem to put my finger on it.
Thanks,
Tim

The Win32_Service WMI class doesn't have a property that would return the service's manufacturer, but the CIM_DataFile class does. So I can suggest the following solution:
Query and enumerate the Win32_Service class instances.
In the loop:
Obtain the PathName property of the current service (it holds the command line for the service).
Extract the service's file name from the PathName.
Obtain the CIM_DataFile class instance corresponding to the service file.
Check the file's Manufacturer property to find out whether or not the service is Microsoft's. For example, on my Vista box, the Manufacturer of all Microsoft services is Microsoft Corporation.
Notes:
Some magic may be required when parsing the PathName and querying the CIM_DataFile class as the PathName can include command-line arguments and may not include known file extensions (e.g. exe).
The Manufacturer property may be Null for some non-Microsoft services.

How to get and cast JNDI object correctly in Liberty

I have a big problem on getting the correct instance or at least casting the instance I got with JNDI-lookup to correct interface at Web Sphere Liberty (16.0.0.4, running on Java 7, though using Oracle Java 1.8.0_45 in the back, developing on Eclipse Neon.2).
When I start the server and the ear containing the EJB, I get the following notification into the log:
The server is binding the xxx.interfaces.MyLocal interface of the MyEJB enterprise bean in the xxx-ejb.jar module of the xxx-ear application. The binding location is: java:global/xxx/MyEJB!xxx.interfaces.MyLocal
Then I have a web application (ear) which has a service provider (with #Produces) for the previously started ejb-service, which will provide the JNDI resource as injectable (#Inject) for the rest of the application (a bit tricky thing, the main idea is to allow to change the lookup location from configuration file + do some other stuff also). It seems to work correctly for all it is supposed to, but when getting the JNDI-resource, it kind of works but not correctly.
If I put the ejb part as a dependency into my web-module, I can inject it directly (#Inject MyLocal myEjb;).
As the injected resource I get an object with the signature:
EJSMyLocal0SLMyEJB_a4549339#cc5d2cdd
with lookup I get an object with signature (at the same time as the inject):
EJSMyLocal0SLMyEJB_a4549339#cdda36a7
(Not the same instance afaik, but the "type" is correct?)
The injected resource is correctly (automatically of course) cast on 'MyLocal' interface and is ok.
When I try to check the resource got with JNDI, it does not qualify as an instance of 'MyLocal' nor as 'MyRemote'? Also the actual cast fails of course with ClassCastException. (MyRemote is basically the same as the MyLocal interface ... MyLocal extends MyRemote, both interfaces are accordingly annotated with #Local and #Remote)
The EJB looks like this at the time of testing...
#Stateless
#Named
#Default
#Local(MyLocal.class)
#Remote(MyRemote.class)
public class MyEJB implements MyLocal, MyRemote { ... }
I also tried to cast the JNDI resource like this.
InitialContext ic = new InitialContext();
Object lookedUpEjb = ic.lookup(lookup); // the 'java:global...' from log
MyRemote jndiEjb = (MyRemote) PortableRemoteObject.narrow(lookedUpEjb, MyRemote.class)
// Tried also casting/checking 'instanceof' to MyLocal...
No difference with that, the same ClassCastException occurs?!

I found this documentation on the Liberty JNDI functionality:
https://www.ibm.com/support/knowledgecenter/SSAW57_liberty/com.ibm.websphere.wlp.nd.multiplatform.doc/ae/twlp_ejb_remote.html
I can't see where I go wrong. How do I cast that object from JNDI lookup to MyLocal or MyRemote interfaces?
---- Note ----
Using the #EJB annotation is not an option (it works though), since it will be hard coded reference to the resource. I want it to be optional though, thus JNDI lookup. #EJB will cause the app to crash when the resource is not available.
The problem is that each application has a different ClassLoader and the object that has been bound into JNDI was loaded with the ClassLoader of the application that defined the EJB.
This should not be an issue for Remote EJB interfaces as the ORB should have taken care of this for you. On a remote call that returns such an object, the ORB will serialize the object (from the target ClassLoader) and then deserialize using the client ClassLoader. For a lookup like this, the PortableRemoteObject.narrow should also take care of this. The failure here appears to just be a bug in the ORB.
In order to support cross application access to Local EJB interfaces, either the Local EJB interface needs to be moved to a shared library, that is used by both applications, or both applications configured to use a single global ClassLoader. See this link for more information about using Local EJB interfaces across applications: Correct way to lookup local EJB in websphere - Getting ClassCastException (Note: this link is discussing traditional WebSphere, but the issue is the same with Liberty, as is the resolution to use a shared library for the interface).

Dangers of using the same GUID in interface definitions?

Suppose:
1) HelpfulUserAtSO answers my SO question with a snippet copied from his production code:
type
IReqBase = Interface(IInterface)
['{B71BD1C3-CE4C-438A-8090-DA6AACF0B3C4}']
procedure FillWithTemplateData;
end;
2) I think Great answer! and blindly copy this into my production code.
3a) We both distribute our apps and user X wants to install both executables on his computer.
What are the consequences?
3b) I buy up HelpfulUserAtSO's company and want to integrate his code (containing the interface definition) into mine (containing the copy. Assume no scoping conflicts).
What are the consequences?
After all a GUID should be 'globally unique'...
If the same GUID are used not within the same process, this is safe to have the same GUID defined. But if, e.g. you access them via COM, it will definitively be confusing.
If you use diverse interfaces with the same GUID in the same process, e.g. by sharing Delphi code units, you may definitively have issues. By convention, an unique GUID should define an unique signature (i.e. set of methods), so the code may think that a given class instance implements all methods of the interface, and it won't be the case. As a result, the internal execution lookup tables (IMT) won't match. You will get a lot of A/V when calling methods.
Take a look at this very complete article for details about how interfaces work, and what is this internal IMT lookup table. The same GUID would mean the same IMT table, which won't be the case for you, so it will just break at runtime.
Just experienced an error due to using duplicated GUID for a new interface that's copied from another.
The consequence was that, since I use Supports, although I was intended to call InterfaceB.Method, but InterfaceA.Method1 got called wrongly even it has a different method signature...I found that with the IDE debugger.
The compiler really should report duplicated interface GUIDs as an error.

Reduce number of class files produced by BlackBerry app

I have developed an order processing application for BlackBerry. When I look at the bin folder I see more than 100 .class files.
I have created a main screen class for adding new clients. The screen has 7 LabelField objects and 7 corresponding TextField objects. This screen also creates a VerticalFieldManager and adds all these fields to it and then adds the VerticalFieldManager to the screen.
For this screen, I have 14 .class files in the bin folder. It seems there is one class file for every field in the progam.
For example:
NewClient.class
NewClient$1.class
...
NewClient$14.class
How do I design the UI in order to reduce the number of compiled classes?
Building a Java-ME app for BlackBerry is a two step process. First the java source code is compiled to class files, then those class files are compiled again into a .cod file, which can be deployed onto a simulator or a device.
'rapc' is the RIM compiler that takes java programs and turns them into a cod or alx file for deployment. 'rapc' can take either java source code, or compiled java classes. Either way, it can produce output suitable for a device.
When starting with Java source files, you can explicitly compile them to class files and hand those class files to rapc or you can pass the Java source to rapc and it will compile the source directly. rapc just defers to the JDK javac compiler when presented with java source code. This means a standard java JDK compiler is always used as the first step of compiling a BlackBerry app, and we can look at standard java behavior to understand what is happening.
In Java, every class that is instantiated has exactly one .class file. For normal classes with a declared name, like this:
public class Foo extends Bar {
}
The .class file is assigned a name that matches the declared class name. However, Java also allows anonymous classes. These take the form of a new Foo() followed by a curly brace which turns this into an anonymous class. This presents a problem, as this anonymous class must be assigned a name at the VM level, despite having none at the Java source level. The solution is to use a character that is invalid in Java source, but valid in the VM, namely $. The anonymous classes are assigned a name based on the enclosing Java class, followed by $, then an integer index based on the number of anonymous classes ahead of this one. In your case, that is NewClient, followed by 14 distinct integers.
To see the behavior you describe, your fields must all actually be anonymous implementations of those classes you mention. To reduce the number of classes, try reusing explicit classes, instead of writing custom behavior with each instantiation.

Other way is to don't use overwrite method on your code such as
btmSave.setChangeListner(new FieldChangeListner()
{
private void fieldChange()
{
}
}
);

REST Datasnap override URI mapping

I wrote a small REST server with the REST datasnap in delphi XE2.
There is a default mapping between HTTP methods (POST, PUT etc.) and the functions defined in delphi, this is done by a delphi component.
This wiki entry describes the URI mapping but also notes that the default mapping can be override by the programmer.
The mapping pattern can be overridden. The user can override the mapping for each type based on class name and method name parameters.
But I didn't find any explanation how to override the mapping.
How can I change the default mapping?
The TDSHTTPService component has events where you can specify the mapping for each type. These events are called RESTMethodNameMapDELETE, RESTMethodNameMapGET, RESTMethodNameMapPOST and RESTMethodNameMapPUT.
This is also explained in the white paper on REST by Marco Cantù, which explains a lot about REST and Datasnap.
I was wondering the same thing, and did some experiments. It seems to be at least partially possible to control the url. Specifically I tried changing the class name part of the url.
Essentially if you are using a TComponent decendant you can name the class anything. This doesn't work if you decend from TDataModule though. In this case you can create and alias class which you can name what you want which decends from your TDataModule.
You need to do some cleanup in the client binding when trying to bind to this, but it seems to work, at least for simple tests.

Best way to use an IoC container for retrieving runtime settings

I have an C# dll project for which I have to store the runtime settings in an external XML file, and this dll will be used in an ASP.NET/ASP.NET MVC application for which I also have to store the runtime settings in a external file.
Which IoC container can be used to create an object with the runtime settings loaded from a specific external file (or app.config/web.config), and also works for web applications running in medium trust? Any howto/tutorial would be greatly appreciated.
So far I've found only this articles:

I'm sending mails from my dll to a variable number of SMTP servers, based on the current record type. For type A I'm using a given SMTP server+port, for type B I'm using an alternate set of server+port values. Of course, I want to be able to modify those values after deployment, so I store them in a XML file.
If I'm storing the SMTP settings as a SMTPConfiguration class with 2 properties (SMTPServer as String and SMTPPort as Int32), is it possible to return from an IoC container the required object based on the given record type, and what is the best way to read the runtime settings in order to build the returning object?
Update2
Let's say I'm storing in the configuration file the following parameters: ASMTPServer, BSMTPServer, ASMTPPort, BSMTPPort.
I can use Castle DictionaryAdapter to read all those settings as properties of an AppConfiguration class.
What is the recommended method to specify that the required SMTPConfiguration class should use ASMTPServer and ASMTPPort values if I'm using a type A record as a parameter (and should use BSMTPServer and BSMTPPort values if I'm using a type B record as a parameter) ? Also, how can I specify that the AppConfiguration is required in this process?
