I'm new to WinDbg and ADPlus, and have a pretty basic question. The documentation in ADPlus.doc talks about an <AllExceptions> section. But I have seen example adplus.config files that use <Exception Code="*">.
What is the difference between these two? Do they do the same thing? Does it matter which one I use?
When using Exception Code you can specify different action for different exceptions.
This is the most common usage in a debug situation.
The AllExceptions is handy if you want to have the same action for all types of exception. However the Log is probably the only sensible action here.
I have never tried to mix both in the same config file !

I am new to Doxygen but I want to use it for a technical documentation for our team.
The background: We have several services in .NET which are going to be called from a JAVA backend through RPC.
Therefore it is quite useful to have those services documented for the JAVA guys.
Using the Doxywizard did help in the first place, but it created a huge overflow of data, which I want to filter, but have no clue how to.
What I want to achieve is, that Doxygen ONLY will use methods, which does have a specific attribute.
For example:
[RpcMethod(id: "GetNumDemo", description: "A demo method")]
public async Task<int> GetNumDemo(JavaDTO dtoObject, int randNum)
I want to have the method within the documentation found by Doxygen since it has the RpcMethod attribute and also cause it have a JavaDTO object, I want to have this class documented as well.
But I am overwhelmed with it ... do you guys can help me? ... at least with a hint within the Doxygen documentation.
Read through the documentation and goodled
Roald has written an excellent guide for the Twincat Eventlogger.

For us this is exactly what we want, there is however 1 thing I haven't figured out. How to get the sourcename of the alarm in multiple languages in the HMI. params::sourceName gives the path in the software (example: MAIN.fbConveyor1.Cylinder1) This path can be customized when initializing the alarm (as Roald has shown). This doesn't work in my case, since I would like to define a generic alarm (example: "Cilinder not retracted within maximum time") that is instantiated multiple times.
I was thinking of using the source as a way to show the operator where the alarm occurs. We use this way (path) already for saving machine settings among other things. The machines we build are installed all over the world, so multilanguage is a must.
Beckhoff does support multilanguage alarm names (when defined), but the source is not defined, but dynamically generated.
Anyone have an idea how this problem can be solved?
If I understand your question correctly, then being able to parameterize the event text with information of the source of the problem should help you out.
If you define the event text as Cylinder {0} has not retracted in time. then you can add the arguments of that text during runtime.
IF bRaiseAlarm THEN
bRaiseAlarm := FALSE;
fbAlarm.ipArguments.Clear().AddString('Alice');
fbAlarm.Raise(0);
END_IF
However, since this also stated in the articles you mentioned, I am unsure if this would solve your problem.
'Alice' in this example, can be hard to localize. The following options come to my mind.
The string can be based on an ENUM. Enums can have textlist support, so if you add your translations there, that should allow multilingual output. However... this does require a lot of setup, placing translations inside your code, and making sure the PLC application is aware of the language that the parameter should use.
Use tags to mark the source device, as tags can be language invariant. It is not the most user-friendly method, but it could work for you. It would become something like: "Cylinder 'AA.1123' did not retract in time.". 'AA.1123' as a tag would have to be stored inside your PLC code as a string. You will have to trust that your operator can relate the tag back to the actual source.
Hopefully, this helped, or else please help me understand the problem better.
I want ask if there is way to get an instance of a component if a job (ex:tmap, tmysqlinput) in tjava code and then manipulate it manually using code?
Thank you
Very hazardous. Looking at the generated Java code will give you some answers (I think so).
In fact, accessing to some objects properties is possible (there is blogs and articles about this) but changing anything seems to be dangerous (IMHO).

Cache2k looks like a very promising caching implementation. Unfortunately the documentation is very limited, which is why I need some help with the following issue. I am using the latest version 0.26-BETA.
According to the documentation the cache is supposed to be created like this:
Cache<String,String> c =
CacheBuilder.newCache(String.class, String.class).build();
String val = c.peek("something");
assertNull(val);
c.put("something", "hello");
val = c.get("something");
assertNotNull(val);
c.destroy();
Unfortunately at least 2 of these methods are deprecated, including the CacheBuilder class itself. I therefore tried creating the cache like this:
org.cache2k.Cache<String, Object> newCache = Cache2kBuilder.of(String.class, Object.class)
.name(cacheKey.toString())
.entryCapacity(100000)
.eternal(true)
.build();
This however throws the "java.lang.UnsupportedOperationException: loader not set" exception.
The question therefore is: how am I supposed to build the cache so that I do not get this exception?
EDIT:
This gives me the same exception:
org.cache2k.Cache<Object, Object> newCache =
CacheBuilder.newCache(Object.class, Object.class)
.eternal(true)
.build();
EDIT #2:
Just one more note: When I copy&paste the code from the wiki page I get an error - as can be seen in the image below.
With what jdk version are you testing? I'll try just removing the <> that are causing the problem for now.
Thanks very much in advance!

Thanks :)

There are new interfaces in place. The deprecated one is still there to support users of old cache2k versions. That will get cleared up in the next weeks. Sorry for the confusion.
Please take a look here for the latest getting started information:
https://github.com/cache2k/cache2k/blob/master/doc/src/docs/asciidoc/user-guide/sections/_start.adoc
This however throws the "java.lang.UnsupportedOperationException: loader not set" exception.
The question therefore is: how am I supposed to build the cache so that I do not get this exception?
Short answer: Either use cache.peek() or wait for 0.27, since then it is working with cache.get() transparently.
Longer answer: In our own applications I use cache.get() only when a loader is defined and cache.peek() when no loader is defined or when I want to inspect the cache only. Reserving cache.get() only for the read through usage, seemed like a good idea. However, I reasoned that it might be a caveat for new users, so I change that behavior and align it to other cache solutions.
Answer to Edit 2:
For an untyped cache use the factory method Cache2kBuilder.forUnkownTypes(). Constructing the anonymous class is only needed for specific types.
(I am also using .NET 4.0 and VS 2010.)
I created a function import returning a complex type, as explained at http://msdn.microsoft.com/en-us/library/bb896231.aspx. The function import and new complex type appear in my .edmx file and in the Designer.cs file. However, the function does not appear when I view the service in the browser, and when I add or update a service reference in the client project, the function does not appear there either - as is to be expected, given the first result.
Creating an imported function and using it seems conceptually very simple and straightforward, and one would think it would just work, as Microsoft's step-by-step instructions appear to suggest: http://msdn.microsoft.com/en-us/library/cc716672.aspx#Y798 (which article shows the SP returning entity types - I tried this also, and it doesn't work for me either).
This blog post shows the addition of a method to the DataService class, which Microsoft's instructions omit: http://www.codegain.com/articles/wcf/miscellaneous/how-to-use-stored-procedure-in-wcf-data-service.aspx I tried adding one method returning a list of entity types and another returning a list of complex types, and still had no success. I still could not access the functions, either directly via the browser or from the client application via a service reference.
Thanks in advance for any help with this.
config.SetServiceOperationAccessRule("*", ServiceOperationRights.All);
MS would do well to add a note to the walkthroughs stating that the above bit of code must be there. (It may be better to enable each operation explicitly than to use "*".)
http://www.codegain.com/articles/wcf/miscellaneous/how-to-use-stored-procedure-in-wcf-data-service.aspx shows that line of code. Also, something it is there in the code, commented out, when one creates the WCF Data Service. Some of us like to delete commented-out code that we aren't using and that seems irrelevant - perhaps doing so a bit prematurely, sometimes.
