linux - Why can I remove file without user permission? -

-

मैंने अनुमतियों की जांच करने के लिए छोटे परीक्षण किया: 

  test @ comp ~ / documents $ स्पर्श test1 test @ comp ~ / documents $ ls -l-rw-r - r-- 1 टेस्ट परीक्षण 0 जुलाई 24 22:14 test1 test @ comp ~ / दस्तावेज $ chmod 044 test1 test @ comp ~ / documents $ ls -l ---- r - r-- 1 टेस्ट परीक्षा 0 जुलाई 24 22:14 test1 test @ comp ~ / दस्तावेज $ cat test1 बिल्ली: test1: अनुमति अस्वीकृत @ COMP ~ / दस्तावेज $ rm test1 rm: लिखने को हटा दें -सुरक्षित नियमित रूप से खाली फ़ाइल "test1" Y प्रश्न @ COMP ~ / दस्तावेज़ $ ls -l कुल 0   
 मेरा प्रश्न यह है, क्यों जब मुझे उपयोगकर्ता पर कोई अनुमति नहीं है तो मैं फाइल नहीं पढ़ सकता, लेकिन मैं इसे निकाल सकता हूं?  लिखें  
 
 
 फाइल को हटाने के लिए  लिखने  पर अनुमति  निर्देशिका  में है जो इस फ़ाइल को शामिल करता है। अधिक जानकारी के लिए:

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...
