I have an object that I've faked with NSubstitute that has a method on it that gets called twice. I'd like to verify that the method has actually been called twice (and only twice). I've poked around the docs and Google with no luck. Any help would be appreciated. Thanks.
This currently isn't supported in NSubstitute 1.2.1 (the feature is implemented in a branch, and will make it to next release).
An alternative for now is to use substitute.ReceivedCalls() which will return an enumerable you can query. Another option is to use When..Do to increment a counter whenever the method is called, and assert that the counter ends up at 2.
Update 2011-11-19: This is supported in NSubstitute 1.3.0, using Received(int). It is documented on the Checking received calls page.

We are trying to add one additional feature to our method for TBO. The feature needs to be executed only when a new document for that object type is imported and should not be executed in any other case like checkin checkout or any changes in attributes.
However the new code is getting called everytime we make any changes to attribute to that document.
We have put that code in doSave() method.
I tried isNew method for distinguish between newly imported Document and other scenarios, however could not get success, may be missing the usage details of the method.
Can anyone suggest anything?
We are on Documentum version 7.2.
I always use isNew() method to check is object new or versioned, I don't remember having problems with it at any DFC version.
Only one thing that comes in mind is to make sure you don't use super.doSave() while inside the code since right after it method will return false.
But this is expected behaviour.
If you really need to do this - some calulations based on programatically preset data - make sure you use value saved within local variable throughout your code.
If you think you are experiencing bug with the method try with another DFC version or report a bug to the Support.
In our company, repository objects must be created with original language EN.
Is there a way to check the logon language in case of creating a new object in the ABAP repository?
Desired behaviour:
SE80 - Create program/class/data element/table/....
==> user exit/badi checks the logon language. When it is not 'EN', the creation will be refused.

I know there is a exit for this but I haven't remember exact name. You can use general purpose for finding exit. Go to SE24 and open CL_EXITHANDLER class, find GET_INSTANCE method and add break point. Then start creating item, it will pause on debugger multiple times, try to find suitable one.
As #mkysoft suggested, you may implement a check in the BAdI CTS_REQUEST_CHECK, method CHECK_BEFORE_ADD_OBJECTS, which is invoked when the object is about to be attached to a transport request. Raise the exception CANCEL to make the attachment fail (and so the object is not created too).
EDIT: sorry, ignore my answer, "this method is NOT released for Customer usage" as said in note 2150125 - Method CHECK_BEFORE_ADD_OBJECTS not triggered
DISCLAIMER: THE METHOD DESCRIBED HERE IS ABSOLUTELY NOT RECOMMENDED.
As correctly pointed out by the other members there is no standard and customer-exposed method to achieve your requirement, but if you absolutely must enable this check during creation you can use the below method. As well as the previously offered to you, it also involves modification of SAP standard.
There is a system BAdi CTS_TADIR_SUBSCREEN that is located inside enhancement point CTS_ES_TADIR_POPUP. They are SAP internal and not released for customer usage, so do this at your own risk.
Implementation procedure:
Step 0. First thing you need to change is a SAP internal usage flag, for which you need Object Access key which can be obtained from SAP or from SAP partner that made the implementation in your org. In virgin state this BAdi throws the error if you try to implement it
So hereinafter we assume that you already ticked off this checkbox in BAdi settings
Step 1.
In order to implement the BAdi one need to implement enhancement spot prior to that. This is the most complicated part, because despite we disabled internality flag the SAP-namespaced enhancements must be stored only in SAP-namespaced objects. By SAP namespace I mean non-Z, non-Y and non-T (Test). This means to implement this enhancement, besides modifying the enhancement definition, one need to create, for example, CTS_ES_TADIR named enh.impl., and save it to non-Z package, which you also need to create. Your enhancement implementations selector should look somehow like this
On the above screen only the second will work, all the rest Z will not.
Every non-Z object need Object Access Key, remember? Too bad. But just to show the proof-of-concept, I will proceed.
Step 2. After you created the enh. implementation in SAP-namespace it will propose you to create the BAdi implementation. The same principle applies here: only SAP-namespaced container for SAP-namespaced objects, hence CTS_TADIR_SUBSCREEN should have implementing class for example CL_TADIR_SUBSCREEN. During the creation of enhancement you will see many warnings
but finally you should have something like this, where all system-named objects are created and the enhancement/BAdi is activated.
Step 3. In order to get the BAdi working we need to enable this subscreen processing
during the playing with enhancement I found out that BAdi class is not being triggered standalone, without screen events not enhanced, so to make it work you need to touch a screen enhancement for screen 100
If you do not wanna modify screen elements logic, just put the dummy enhancement in SHOW_TADIR dialog module in the end of the include LSTRDO18
PROCESS BEFORE OUTPUT.
MODULE SHOW_TADIR. "<-- create the dummy enhancement here
CALL SUBSCREEN subs_info INCLUDING gv_badi_prog gv_badi_dynnr.
for example declaration statement like I did
Step 4. Activate your created BAdi class and put the necessary logic there. I wasn't able to trigger method GET_DATA_FROM_SCREEN, but PUT_DATA_TO_SCREEN worked fine
If we put this simple processing for your requirement
METHOD cts_if_tadir_subscreen~get_data_from_screen.
IF object_data-l_mstlang <> 'E'.
MESSAGE 'Objects in non-English languages are not allowed!' TYPE 'A'.
ENDIF.
ENDMETHOD.
it will not allow creating objects in languages other than English.
The check in method get_data_from_screen is being done before showing the screen so language is determined from system logon settings. If to play more with this BAdi, I suppose the method GET_DATA_FROM_SCREEN can also be enabled, which will make it possible to check user input, i.e. the case when the user gonna change the default language.
We’re using Ninject.Extensions.Interception (LinFu if it matters) to do a few things and I want to know if its possible to return a value form the method being intercepted.
EG
A Call is made into one of our repository methods
Our Interceptor gets the BeforeInvoke event, we use this to look into the ASP.NET Cache to see if there is any relevant data
- Return the relevant data (this would cause the method to return immediately and NOT execute the body of the method
- Or Allow the method to run as per normal
Extra points if in the AfterInvoke method we take a peek at the data being returned and add it to the cache.
Has anybody done something similar before?
From your question I assume that you derive from SimpleInterceptor. This will not allow to return imediately. Instead you have to implement the Iinterceptor interface. You can decide to call the intercepted method by calling the Proceed method on the invocation or not.
I wrote this code to hook API functions by changing the address in the IAT and EAT: http://pastebin.com/7d9N1J2c
This works just fine when I want to hook "recv" or "connect". However for some unknown reason when trying to hook "gethostbyname", my hook function is never called.
I tried to find "gethostbyname" in a debugger by taking the base address of the wsock32.dll module + 0x375e, which is what the ordinal 52 of my wsock32.dll is showing as offset. But that just makes me end up in some random asm code, not at the beginning of a function.
The same method however works fine for trying to find the "recv" entry point.
Does anyone see what I might be doing wrong?
I recommend this tool:
http://www.moduleanalyzer.com/
They do exactly the same and show the url that was connected with that API.
The problem is that there are more than one API to translate an url to an address. The application you are hooking may be using another version of the API that you're not intercepting.
Run some disassembler like IDA and attach to your process after you hook this functions, ida get apply changes on attaching and play process and check what is wrong.
In other way you have many libraries to do hooks with trampolines like Microsoft Detours, NCodeHook etc.
Here is a question about IMFActivate::ActivateObject and IMFActivate::ShutdownObject in Media Foundation.
According to MSDN, the component that calls ActivateObject is responsible for calling ShutdownObject.
But there are two examples not following this rule:
http://msdn.microsoft.com/en-us/library/dd388503%28VS.85%29.aspx
and
http://msdn.microsoft.com/en-us/library/dd317912%28VS.85%29.aspx
In these two examples, they call ActivateObject and then release IMFActivate interface without calling ShutdownObject method.
This is going to lead to memory leaking, right? Or there is another way to release the resource occupied by the object?
(Can I use IMFMediaSource::Shutdown to release the object instead of using IMFActivate::ShutdownObject)
Thanks in advance.
You're right that you're supposed to call IMFActivate::ShutdownObject when you're done using the object you activated. However, notice that the sample in question is instantiating an IMFMediaSource to be returned in an out param.
HRESULT CreateVideoDeviceSource(IMFMediaSource **ppSource)
If CreateVideoDeviceSource were to do a ShutdownObject on the IMFMediaSource it instantiated and then hand it back to you, it would be in a shut-down state and therefore probably unusable.
To answer your question about what you're supposed to do about this, you can probably get away with a pMyMediaSource->Shutdown() after you're all done using it.
More info: IMFActivate's other use in Media Foundation is for allowing an MF object to be instantiated in a different process (useful because the MF Media Session will play DRM-protected content in a separate process); in that case, the MF Media Session will indeed call IMFActivate::ShutdownObject on any IMFActivates you gave it.
