Access static class variable of parent class in Python -

Access static class variable of parent class in Python -

September 15, 2013

मेरे पास ऐसा कुछ है

  class A: __a = 0 def __init __ (self) : ए .__ ए = ए .__ ए + 1 डीईफ़ ए (स्व): रिटर्न ए .__ एक क्लास बी (ए): डीएफ़ __इनट __ (एसआई): # मैं ए। ए .__ ए = ए .__ ए + 1 # डीईफ़ ए (स्वयं) काम नहीं करता है: रिटर्न ए .__ ए

क्या मैं __ ए वर्ग चर < कोड> बी ? यह a के बजाय __ ए लिखना संभव है, क्या यह एकमात्र तरीका है? (मुझे लगता है कि जवाब शायद कम हो सकता है: हाँ:)

अतः, __ एक स्थिर चर नहीं है, यह एक क्लास चर है और डबल अग्रणी अंडरस्कोर की वजह से, यह एक चर है। यह छद्म निजी बनाने के लिए है, इसे स्वचालित रूप से _ & lt; classname & gt; __ & lt; variablename & gt; के बजाय __ & lt; variablename & gt; के नाम से बदल दिया गया है। यह अभी भी उस वर्ग के के रूप में __ & lt; variablename & gt; के उदाहरणों तक पहुँचा जा सकता है, उपवर्गों को यह विशेष उपचार नहीं मिलता है।

  मैं सुझाऊंगा कि आप डबल अग्रणी अंडरस्कोर का उपयोग नहीं करते हैं, (ए) से चिह्नित करें कि यह निजी है, और (बी) नाम मैंगलिंग से बचने के लिए।

Unable to get a fresh ASP.NET MVC project running with Visual Studio
2008 -



    This is a very basic question. I'm asking this silly about this, but I'm stuck something else and hopefully That something here can save me some time. So I open VS2008, to download the new ASP.NET MVC web application and click OK I want to prepare a test project. I debug my new MVC project to hit F5 then I enable the debugging to the web. I choose to modify the config file. It goes where I get a page load error.   Firefox can not establish a connection to the server on the local host: 57323.   Do I have to do something special for Vista? Or I should do something with IIS   Thanks for helping a noob   6/30/2009 update   OK, I think that I VS2008 may need to be reinstalled with the ASP.NET Development Server port. I have tried to do everything that I have suggested. I've marked Default.aspx as the start page. I tried to open it in Firefox / IE 8 / and Chrome. I tried to uninstall / reinstall ASP.NET MVC, which was not working. I tried telnetting with Putin with a local ho...






delphi - Mouseover hint for TChart series value -



    I am using a TChart in Delphi 7, and I want to display charts sometime. I am using the following code to set the chain value to a database query:    chart1.FreeAllSeries; Chart1.SeriesList.Clear; Chart1.AddSeries (TBarSeries.Create (self)); TBarSeries (chart1.Series [0]) BarStyle :. = BsRectGradient; Stop starting with Query 1; Executed; While EOF does not start chart1.Series [0]. Add (field 'flags' ('sum_actual_days'), Field Astrstring ('contract_no')); the upcoming; End; End;    Each time (value) is now showing both the label below the bar and in a yellow rectangle above the bar.   Rather than repeating the amount of label twice, I have some additional information from the query that I would like to show above the bar rather than the label (or, preferably, as a mouseover signal). Can it be done with TChart? And how ...?      This can be done with a TChart using the onMouseMeave event of the chart. Something like this should start with you:    Process TForm...






sql - Incorrect syntax near the keyword 'table' -



    I'm getting this error what I'm doing is trying to get data from a table and a db and Keep it in another DB and table. The tables are not exactly the same, I am using a FETCH cursor, so I get the first line from the DB1 table and then keep each column value in the declared variable. Then I run an assembly statement in db2 table and get the next value. All of these are working properly because it runs properly, but in the end I get this error,   Wrong syntax near the keyword 'table'.   In the entire transaction details, an attempt / catch with the error of expression in the Cat block, apart from this, I do not know what is the reason for it.   Here is the code    added to prevent additional result set at SET NOCOUNT - Interfering with the SELECT statement. Set nosenate on; TRY begin transaction sets ITENDITY column off --TURN identity_insert [dB] start [dbo] [TEST] all CONSTRAINTS table --TURN [dB] change [dbo] [TEST] NOCHECK barrier All -....
