ruby - Send allows access to private variables -

-

निम्न कोड पर विचार करें: 

  def create_class (class_name, superclass, और ब्लॉक) क्लेस = क्लास.न्यू सुपरक्लास, और ऑब्जेक्ट ब्लॉक। ऑब्जेक्ट.कंस्ट_सेट क्लास_नाम, क्लेस एंड

मेरे द्वारा किए जाने के बाद: 

  create_class ('उपयोगकर्ता', एक्टिवरेकॉर्ड: : बेस)

निम्न ठीक है: 

  Object.send (: remove_const,: उपयोगकर्ता)

लेकिन यह: 

  Object.remove_const: उपयोगकर्ता

इस में परिणाम: 

  NoMethodError: निजी विधि `remove_const ' वस्तु के लिए कहा जाता है: कक्षा

? क्या मेरे लिए कोई मतलब नहीं है ... रूबी की एक्सेस जांच को ओवरराइड कर सकता है? कृपया मदद करें!

ऐसा लगता है कि रूबी की पहुंच जांच ओवरराइड करता है।

< / P>

मेरा अनुमान है कि आप चीजों के साथ अच्छी तरह से खेलना चाहते हैं अन्य लोगों ने निजी बना दिया है यदि आपको किसी वर्ग की विधियों को कॉल करने के लिए भेजने का उपयोग करना आवश्यक है जिसे आपने नहीं बनाया है, तो आपको इसे पहले कॉल करना चाहिए।

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
