exception - CX_ROOT with Message Class -

-

I have several custom exception classes, which were created "with message class" since I did not receive a message directly from them So, I want to create a utility method which returns BAPIRET2 to IF_T100_MESSAGE ~ T100KEY with the exceptions given on the basis of values. However, I can not provide that method with a normal CX_ROOT import parameter because it is not class-enabled message. I can not even create a normal message-enabled exception class because the new classes are CX_STATIC_CHECK is inherited from one of the , CX_DYNAMIC_CHECK , or CX_NOCHECK .

How do I get message details with an unspecified exception? Should I make any such method that gets a CX_ROOT and then three calls to the imported methods for each of the three potential sub-classes? Or what are the better options?

You can prepare a type descriptor (one time) of the interface: 

  data: lr_t100_descr type reef to cl_abap_intfdescr lr_t100_descr? = Cl_abap_typedescr = & gt; description_by_name ('IF_T100_MESSAGE')   
 And then check each exception because it comes your way:  
  Data: lr_t100_exception Type Reef to I_t100_message. IF lr_t100_descr-> Does apply_ (ir_any_exception) = abap_true Lr_t100_exception? = Ir_any_exception "... ENDIF.

python - Writing Greek in matplotlib labels, titles -

Image
I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

c# - LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method -

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...
