c# - Initialize child class from base definition -

-

Apologies if this is a commonly asked question, but I have a lot of googling for a while to spend the answer and no definitive answer could get .

I have an abstract class in which fields are included (definitions of) Other abstract classes are then used for the solid implementation of properties. However, when I want to start implementing that intangible class, then I want to populate those areas with the special implementation of the field. . In fact, even that seems confusing here so here Example 

  // My main abstract class public abstract class Log {public virtual bool AppendLog {set {_logWriter .ppend = value; }} Internal logger _logWriter; // LogWriter is another abstract class public abstract zero zero addEntry (string input); } // abstract class implementation of the public square SyncLog: Log {public SyncLog {// I // Want to start LogWriter abstract class parents with the actual implementation SyncLogWriter: LogWriter _logWriter = new SyncLogWriter (); } Public override zero AddEntry (string input) {content.AddEntry (input); _logWriter.Write ("hello"); }}

Although it technically complies with and works, there is a problem. Use _logWriter while I could use only declare methods and properties in the abstract class LogWriter am, but is not implemented in addition to the additional child (Sinklograitr). While technical it makes sense I wonder if there is any way to approach the same, but all the extra stuff available available in SyncLogWriter is available?

An additional member _syncLogWriter got square inherited SyncLog < / Code>. Apart from this, it is even better to get started using your _logWriter builder for the base class and make it private. 

  // My main essence log for the public abstract category {protected log (logword log log) • {_logWriter = logWriter; } Public Virtual Bull AppendLog {Set {_logWriter.Append = value; }} Private logger_log author; // LogWriter is another abstract class public abstract zero zero addEntry (string input); } // abstract class implementation of the public square SyncLog: Log {private SyncLogWriter _syncLogWriter public SyncLog (): this (new SyncLogWriter ()) {} private SyncLog (SyncLogWriter logWriter): base (logWriter) {_syncLogWriter = logWriter; } Public override zero AddEntry (string input) {content.AddEntry (input); _syncLogWriter.Write ("hello"); }}

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 ...
