How could metaprogramming be used to reduce redundancy in this Ruby code? -

- 

 <कोड> वर्ग डिवाइस डीईएफ़ प्रारंभ (DEVICE_ID, data_resource) @id = DEVICE_ID @data_resource = data_resource अंत डीईएफ़ display_device मोड = @ data_resource.get_display_device_mode (@id) प्रीसेट = @ data_resource.get_display_device_presets (@id) सारांश = "display_device: # {मोड} ($ # {प्रीसेट})" वापसी "* # {सारांश}" अगर प्रीसेट == "XTC909" सारांश अंत डीईएफ़ चिप मोड = @ data_resource.get_chip_mode (@id) प्रीसेट = @ data_resource.get_chip_presets (@id) सारांश = "चिप: # {मोड} ($ # {प्रीसेट})" वापसी "* # {सारांश}" प्रीसेट अगर == "XTC909" सारांश अंत डीईएफ़ input_device मोड = @ data_resource.get_input_device_mode (@id) प्रीसेट = @ data_resource.get_input_device_presets (@id) सारांश = "input_device: # {मोड} ($ # {प्रीसेट})" वापसी "* # {सारांश} "यदि presets ==" XTC909 "सारांश के अंत का अंत

जैसा कि आप ऊपर दिए गए कोड से देख सकते हैं, वहाँ बहुत कम है redundan तरीकों के भीतर सीआई चाहे इस अतिरेक को कम करने का सबसे अच्छा तरीका मेटाप्रोग्रामिंग है , मुझे यह जानने की उम्मीद है कि रूबी में मेटाप्रोग्रामिंग का उपयोग करने के लिए कुछ पुनरावृत्ति को कम करने के लिए अगर कोई कुछ सुझाव प्रदान कर सकता है।

< / Div>

यहाँ एक ऐसा संस्करण है जो मेटाप्रोग्रामिंग का उपयोग करता है, हालांकि मैं उस पद्धति में डालकर यह डुप्लिकेशेशन को निकाल देता हूं जहां यह संबंधित है। / p> 

 <कोड> वर्ग डिवाइस डीईएफ़ प्रारंभ (DEVICE_ID, data_resource) @id = DEVICE_ID @data_resource = data_resource अंत डीईएफ़ resource_summary (RESOURCE_NAME) मोड = @ data_resource.send ( "मिल _ # {RESOURCE_NAME} _mode", @id ) Presets = @ data_resource.send ("get_ # {resource_name} _presets", @id) सारांश = "# {resource_name}: # {मोड} ($ # {प्रिसेट्स}}" वापसी "* # {सारांश}" अगर प्रीसेट == "XTC909" सारांश अंत डीएफ़ self.resource_accessor (* नाम) names.each {| संसाधन | Define_method (संसाधन) {resource_summary संसाधन}} अंत resource_accessor: display_device,: चिप,: input_device end

यदि आप वास्तव में उस कार्यक्षमता के लिए एक विधि बनाना नहीं चाहते थे, तो आप इसे बदल सकते हैं संसाधन_समुरी पद्धति को संसाधन_समुरी विधि के शरीर से कॉल करें।

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...

PHP - get image from byte array -

-
I am trying to create a back-end for my mobile application. I am sending the content of an image in the body of the HTTP request (output stream) as a byte array, I want to read this stream of bytes in PHP scripts and take back an image. Can anyone tell me how can I do this? Thank you. You can obtain the request body $ body = Reading from file_get_contents ('php: // input'); What you do with that data Depending on you, you can write the data in a file as you mentioned that this is image data, you can drop the data into the object can do. Another option is to use and load the image.

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...
