javascript - How force use "this" in coffeeScript? -

-

मुझे ऐसे मदर क्लास में एक स्थिर विधि को परिभाषित करना होगा: 

  class @ motherclass @ परीक्षण = = & gt; Foo.bar (this) # @ @   
 के साथ, लेकिन अगर आप इसे कोशिश करते हैं :, आप देखेंगे कि यह "मदरक्लास" में स्वत: संकलन करता है।  
 इसलिए, यह वही है, लेकिन वास्तव में नहीं!  
 वास्तव में, मेरे पास मदरक्लास के साथ विरासत में बाल क्लास है  
  @ChildClass @MoreClass तक फैलता है   < P> तो ChildClass.test () परिभाषित किया गया है लेकिन इस तरह से:  
  फ़ंक्शन () {वापसी फूबार (मदरक्लास); };   
 मुझे फू.बार के प्रथम परम की आवश्यकता है ChildClass में ChildClass (और ChildClass2 अगर मैं ChildClass2 वर्ग बना देता हूँ ...), नहीं MotherClass इसलिए मुझे इस गतिशील की ज़रूरत है, स्थिर नहीं।  
 कॉफी स्क्रिप्ट में "यह" कितनी ताकत लिखती है?  
 thx।  
 संपादित करें: मैंने पाया "बुर्क!" समाधान ^^ = & gt; "एवल ('यह')", लेकिन यह वास्तव में crapy तरीके है कैसे बेहतर है?   
 
 
 वसा तीर के बजाय स्कीनी तीर का प्रयोग करें:  
  वर्ग @ मार्थ क्लास @ टेस्ट = - & gt; Foo.bar (this)   
 वसा तीर आपकी कार्य को  MotherClass ।

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...
