When I do a \ dt in psql, then I get a list of tables in the current schema ( public by default).
How do I get a list of all the tables in all schemas or any particular schema?
In all schemas:
= & gt; \ Dt *. *
In a particular schema:
= & gt; \ Dt public *
It is possible to use
\ dt (public | s). (S.T.T) List of Relationship Schema | Name | Type | Owner -------- + ------ + ------- + ------- Public S | Table | CPN Public | T | Table | CPN S | T | Table | CPN
An advanced user can use regular expression notes such as character classes, for example [0- 9] to match any number, all regular expressions Special characters, 9.0. Which is taken as a separator in the form of the above, which is translated into regular expression. ,? Which is the translation, and $ which is literally matched, can you simulate these pattern characters by writing? For, R for (R + |), for R , or (R |) R?. $ Is not required as the character of regular expression because the pattern should match the whole name, in contrast to the regular interpretation of regular expression (in other words, $ automatically associated with your pattern). Writing * In the beginning and / or at the end if you do not want to anchor the pattern, note that within the double quotation marks, all the regular expression special characters lose their special meaning and match it literally. Also, regular expression special characters are literally matched in operator name patterns (i.e., \\ the argument).
So I have two files for which I need to turn, call them: example.cc and example.h < / P>
We have been told that their test code will only contain "example.h". I usually include the example # example "example.cc" because it will already include example example.h is.
When I run the test code, I just get "an unspecified reference for example: Example ..", whenever I mention the example in the test code, it is clearly because the test The code can only see my delcarations in example.h, not their actual implementation.
What am I missing? I have included example.cc in Example #, but this is clearly not correct.
It appears that your professor has some other type of file, called Professor_man.cc , And they will compile this project like this:
g.+ example.cc professor_main.cc -o project
in their professor_main.cc One line will be
#include "example.h"
and also use some of your functions, and potential tests that they are doing the right thing Are:
Now, if they do not include #home.h, or if you have not created that file correctly, they will get a compilation error at professor_main.cc, Because it is not about example_add (int, int), the important line header should be in the file and it removes this error:
int example_add (int a, int b);
This is called Function Declaration.
If everything has been done properly, but your professor has made a mistake and tried to compile the project without an example. In this way:
G ++ Professor_man.cc-o project
Then they should have an "undefined reference" about a linker < / Em> error will be found "example_add ().
What is missing definition :
int example_add (int a, int b) { Return a + b;}
This should be in your example.cc file, and if the professor also includes that on their compilation command line, everyone should be well.
However, if you enter # example "example.cc" in your header file Effectively, you then copy and pasted example example.cc in professor_main.cc, because it's #included in but it's clearly still in your file, example.cc so if Your professor tried to do this:
g ++ example.cc professor_main.cc -o project
make them a several definitions < Error from linker / em>, because function example_add () is defined by twice << p> Generally, then, what you probably should do in your source file (.cc) Definitions and all your functions in your header file (.h) announcements someone other. Try compiling it with a cc file and use it to see how it works.
मैं uitableview ios6.1 में छवियों को कैसे लोड करूँ?
मैं वर्तमान में SDWebImage का उपयोग कर रहा हूं और यह काम करता है। लेकिन कभी-कभी यह छवि को लोड नहीं करता है
क्या कोई अन्य लाइब्रेरी है जो मैं उपयोग कर रहा हूं? मैं आईओएस में शुरुआत कर रहा हूं और इससे मुझे बहुत मदद मिलेगी।
अग्रिम धन्यवाद।
यह वह कोड है जो मैं अब के लिए उपयोग कर रहा हूं:
- (UITableViewCell *) तालिकादृश्य: (UITableView *) तालिका दृश्य सेलफोराअटइंडपैथ: (NSIndexPath *) सूचकांकपथ {स्थिर NSString * MyIdentifier = @ "MyIdentifier"; UITableViewCell * सेल = [टेबलव्यू डेक्यूवर पुन: योग्य CellWithIdentifier: MyIdentifier]; अगर (सेल == नीला) {सेल = [[[यूआईटीबलव्यूजेल आलोक] initWithStyle: UITableViewCellStyleDefault reuseIdentifier: MyIdentifier] autorelease]; } // यहां हम नए प्रदान किए गए सेट इमेज वाईथ URL का उपयोग करते हैं: वेब छवि को लोड करने के लिए विधि [cell.imageView setImageWithURL: [NSURL URLWithString: @ "http://www.domain.com/path/to/image.jpg"] प्लेसहोल्डर छवि: [UIImage imageNamed: @ "प्लेसहोल्डर पेज"]]; Cell.textLabel.text = @ "मेरा पाठ"; रिटर्न सेल; }
मैं इसे एक उत्तर में डाल रहा हूं क्योंकि यह टिप्पणी के लिए बहुत लंबा था :
SDWebImage पैकेज इसकी कैशिंग के लिए मजबूत है - विशेष रूप से ऑन-डिस्क कैशिंग जो आईओएस (विभिन्न ओएस संस्करणों के विभिन्न स्तर / कैशिंग के प्रकारों के समर्थन के साथ) में दर्द का एक सा हो सकता है। SDWebImage बहुत अच्छी कार्यक्षमता भी प्रदान करता है - आप अपने गीथहब पृष्ठ पर मुख्य बिंदु देख सकते हैं (यह शीर्ष पर बुलेट सूची है)।
अगर यह केवल UIImageView की श्रेणी है जो आप के बाद है (जो setImageWithURL: placeholderImage: विधि) तो कुछ (मैं 'सबसे ज्यादा' कहना चाहूंगा, लेकिन मैं डेटा / आंकड़ों के साथ इसे वापस नहीं कर सकता) लोगों को पहले से ही नहीं होने की संभावना से AFNetworking का इस्तेमाल होता है उस का उपयोग करके उनके नेटवर्क स्टैक के रूप में। हमारे उत्पादन ऐप एएफएनेटवर्किंग का उपयोग करता है + SDWebImage क्योंकि हमें व्यापक वायुसेनात्मक कार्यक्षमता की जरूरत है लेकिन डिस्क-कैशिंग पर भी।
ओह और छवियों के संबंध में डाउनलोड नहीं करना - संभव है कि यह एक नेटवर्क समस्या थी तथ्य यह है कि आपको कोई त्रुटि नहीं मिली है और एप को दुर्घटना नहीं हुई है, यह कार्यक्षमता का बहुत अधिक है, जो SDWebImage जोड़ता है। इसी तरह की विधि को कार्यान्वित करने के लिए त्रुटि मामलों (नेटवर्क त्रुटि बनाम अनधिकृत बनाम गलत यूआरएल) और मुख्य थ्रेड को अवरुद्ध किए बिना यूआईएमएजेव्यूयूई को भी अपडेट करने की आवश्यकता होगी, जो सभी लागू करने के लिए काफी जटिल हो सकते हैं न कि सिर्फ शुरुआत के लिए बल्कि मध्यवर्ती प्रोग्रामर के लिए भी । कार्यक्षमता सरल दिखती है - एक छवि डाउनलोड करें, प्लेसहोल्डर का उपयोग करें, और छवि आने पर अपडेट करें - लेकिन यह निश्चित रूप से एक तुच्छ कार्य है।
मैं जो काम पूरा करने का प्रयास कर रहा हूं वह गतिशील रूप से तय करना है कि रनटाइम पर किस दृश्य का उपयोग करना है, यह DataContext में ListBox कोड>। सरल शब्दों में, मैं & lt; दृश्य: ViewName & gt; को एक डेटा बाइंडिंग के साथ बदलना चाहता हूं जो उचित दृश्य देता है।
मैं अपने ऐप के लिए प्लग-इन्स प्रदान करने के लिए MEF का उपयोग करता हूं उचित होने पर आइटम प्रदर्शित करने के लिए कस्टम दृश्य प्रदान करने की आवश्यकता हो सकती है डिजाइन समय पर मुझे सभी संभावित दृश्य प्रकार (वे गतिशील रूप से डीएलएल से लोड किए जा सकते हैं) नहीं जानते हैं, इसलिए एक सरल DataTemplateSelector ऐसा नहीं करेगा।
फिर, प्रत्येक DataTemplate स्वचालित रूप से प्रत्येक संबंधित ViewModel को प्रस्तुत करने के लिए WPF द्वारा उपयोग किया जाएगा।
यह भी ध्यान रखें कि आप DataTemplateManager.RegisterDataTemplate () सूची बॉक्स को दिखाने से पहले किसी भी समय, ताकि आप सैद्धांतिक रूप से ऐसा कर सकते हैं जब एमईएफ भागों को लोड करते हैं।

When I try to export my database from mysqlworkbench away from local level,
I'm getting some lower version error
mysqldump version mismatch [content] mysqldump.exe is version 5.5.16, but the MySQL server has to be abandoned version 5.6.10-log. Since the version of mysqldump is older than the server, some features can not be backed up correctly. It is recommended that you upgrade your local MySQL client program, with mysqldump equivalent to the target server or with the newer version. Dump tool's path preference - & gt; Administrator - & gt; The path of the Mysqldump tool
I am trying to find a solution, I searched for a solution on Google but could not find a good answer to solve this problem.
Does anybody know how to fix this problem in mysqlworkbench?
Go to Edit - Preferences - Administrator - Path to Mysqldumptool: (For this, see Mysql / bin / then file mysqldump.exe in your MySQL server installation folder And then click OK), then try to backup it.
I am trying to validate the server certificate in an iOS application. There is a problem with
:
- (zero) connection: (NSURLConnection *) connection will be the Sandroquestfertification challenge: (NSURLAuthenticationChallenge *) challenge
When I put this method on
However, when I put it on my production server (Government Ca), this method does not just call.
This proof, I suppose, can be considered as a self-signed certificate, because if you do not have GOV serials installed, you receive the message "This Connection Unreliable" in the browser.
What is the ISENDRequestForAuthenticationChallenge called for enforcement of force in any way and can check self-signed certificates?
Thank you!
The question was asked some time ago, but I thought I would give an answer for people to come Would like to
As I unders the challenge of the sleepiness certification, only every 10 minutes per host is called accordingly. The result of the challenge is being cached for the performance. Cash expires in 10 minutes ()
Good insight is given here by jblack , which is a reference to the Apple forum:
When I had a similar question and a problem, the thing that slipped me was that I had used the same host for many operations in the app, so the challenge has been accepted elsewhere, but my Exclude from NSURL connection Halley has not expired, so I never got a challenge (no need).
Try to separate this request to the host and then you should get a callback.
I have a particle system for which I basically track coordinates. So far I was output all the coordinates in the files, then do it with a Gnuplot script and using FFPAP to make a video from PGG. To leave all file I / O, I did not take any advantage before OpenGL, so I thought of installing a pipe for Gnuplot.
I like it in MSVC 2012: FILE * gnuplotpipe = _popen (GNUPLOT_NAME, "w"); Setwuf (Gnuplotipipe, Faucet, _IONBF, Faucet); // Setbuff (GnuplotPipe, Faucet); Fprintf (gnuplotpipe, "set word png \ n"); Fprintf (gnuplotpipe, "size size 720, 480 \ n"); Fprintf (gnuplotpipe, "set size ratio -1 \"); Fprintf (gnuplotpipe, "unset \ n"); Fprintf (gnuplotpipe, "set xrange [-% d:% d] \ n", RANGE + 100, RANGE + 100); Fprintf (gnuplotpipe, "set yrange [-% d:% d] \ n", RANGE + 100, RANGE + 100); For calculating fprintf (gnuplotpipe, "% f% f \ n", particle [//] for the (time-phase) // Doo Stuffprint (gnuplotpipe, "plot" - '\ n "); (all particles) I] - end for ffush (gnuplotpipe, "e \ n"); // fflush (gnuplotpipe); _pcloce (gnuplotpipe); <-> <->, x [i] -> y); end for fprintf; gnuplot -persist instead of popen and instead of
Pclose , and setbuf instead of setvbuf . It was already with much testing and error.
This is very consistent in Linux I plot '-' command and after that can read unreadable text. Nothing opens in Windows This is amazing in Windows, as sometimes it will work and I will be able to do data streaming on the GnuPlot "MS Windows" window (I mean the console is not output and it is amazing for me because I am not using wgnuplot_pipes.exe). Nothing has been plotted. The window is closed for some time-period for a second time W Lot will, but in separate windows for each time-step. Occasionally, it will crash or it will work but send unpleasant text.
I am working with 100 particles most of the time. I can have more than 10,000 time-consuming steps. I do not know that this is a lot. I suspect cut-offs in windows or some things, though I'm setting buffer with a tap. I am working in WinXX64 and QT in MSVC in Linux Mint X64 in versionbank I am using gnuplot 4.7 (win) and 4.6.0.8 (linux). I have seen very much in SO and only one problem I have found is that -persist is not actually released in windows. Any help would be appreciated.
This question is not unanswered. Puts a single window with a silly animation.
However, I would not be surprised that some other drivers try to open a window for each frame
import subprocessation F = subprances. Popen (['/ usr / bin / gnuplot', '- persist'], stdin = subprocess.PIPE, shell = falls) f.stdin.write ('set term x11 \ n') f.stdin (I) == 50: d * = -1 i + = 1 If IRCTET = 1000 IT = = d f.stdin.write ('plot' '\' points with lines 4 PS2 \ n ') in range Range (0,500): F.stdin.write ('% f% f \ n'% (float (j), math.sin (float (j) / float (abs (i) +1)))) f.stdin.write ('e \ N ')
There is an alternative argument in the SQL stored procedure, say id (int) . For the sake of simplicity, say, I have to return a result set with the extra ... and id = @ id , if the argument is not null. If I do not only return the result set
How do I avoid writing the 'core' of the query twice? CTE in rescue?
You can try: < @id If the null query compares your ID column then <> iTool (@id, id)
for yourself, which is always true, otherwise The parameter is used.
I can get the PivotViewerItemTemplate 2 level to work properly, but not three

I want to send data from this selection (which is "mutual" for both of these forms) when any of these forms are sent (such as an additional field withind sender form ). Is this a simple solution for that?
Add a hidden information and valid markup with the initial label tag etc.
& lt; Select ID = "group_dropdown" name = "selection input" & gt; & Lt; Option value = "0" & gt; All & lt; / Options & gt; & Lt; Option value = "1" & gt; 1 option & lt; / Options & gt; & Lt; Option value = "2" & gt; 2 options & lt; / Options & gt; & Lt; / Select & gt; & Lt; Form method = "post" class = "form-inline" id = "form11" & gt; & Lt; Label & gt; & Lt; Input type = "text" name = "1forminput" placeholder = "0" /> & Lt; Input type = "hidden" name = "selection_name" /> & Lt; / Labels & gt; & Lt; Button type = "submit" class = "btn btn-success ml40" & gt; Save & lt; / Button & gt; & Lt; / Form & gt; & Lt; Form method = "post" class = "form-inline" id = "form22" & gt; & Lt; Label & gt; & Lt; Input type = "text" name = "forminput" placeholder = "0" /> & Lt; Input type = "hidden" name = "selection_name" /> & Lt; / Labels & gt; & Lt; Button type = "submit" class = "btn btn-success ml40" & gt; Save & lt; / Button & gt; & Lt; / Form & gt;
Then fill out the selected input when the value of the selection changes:
$ ('# group_dropdown'). ('Change', function () {$ ('[name = "select_value"]'). Val (this.value);}) Trigger ('change');
and selection values will be sent with both forms when they are submitted, and will be accessed:
All I am trying to do is pass the MVC action method to the array of strings / ints. But the data always comes back empty, what am I doing wrong?

I'm pretty sure that the model binder is not sure that the list / array must also be bound.
Consider:

If JSON has been passed as an array of values, then which parameter is also binded? JSAN can be more complex than FormMS submissions, so it requires a bit more definition too. For example, the following ideas will work for the previous idea.

I am trying to get started with an API to test my company's mobile applications. I want to use Python binding to write scripts, and I have to start with the Android app.
I have an appium example that all are working, I can run chunky Android and test work, and I run the sample app android.py Can i
But I'm a total newbie and in my company's app I do not have a clear picture to identify the controls. I have experience with Python, so I thought I would just make a list of control elements. And I will introspect them.
I'm stuck! All methods like driver.find_elements_by_tag_name () require a specific identifier (or at least I do not get any wildcard that works).
How can I self help an appium tree represent the Android app under testing of the elements? How can I calculate all the elements so that I can introspect them? Can I run a tree to find all the elements in the app?
I was hoping that I could capture the elements without getting the source code for the applet, I could create the app in Eclipse. But I can do this if necessary.
PS I like to use Python, but if it works better then it will open to do some more introspection. I can still write the actual tests in Python Other languages may not be quite better

Background: I have a web site that uses tinnies to edit HTML non-breaking space and ; HTML entities like x22c4; Tinymce is converting to UTF-8 characters, even if I am using entity_encoding: "named" option. I store it in a MySQL table which is UTF-8 when the same HTML is retrieved for editing again, multi-byte characters are separated by tinxes in individual characters. Tinymce has verified that this is a bug.
The question is: how do I convert all multi-byte UTF-8 characters into HTML entities without breaking the HTML?
I tried to have the following in PHP, but multi-byte UTF-8 characters have been deleted:
I also tried mb_encode_numericentity, but I could not figure out what should I use for the parametric parameter.
Update: I have PHP 5.3.17, which is not supported ENT_HTML5, so I removed it. Now it works for non-breaking space, but not for other multi-byte UTF-8 characters.
A few years ago, I went to the section of this code in PHP documentation: < Pre> function utf8_to_html ($ data) {back preg_replace ("/ ([\\ xC0 - \\ xF7] {1,1} [\\ x80 - \\ xBF] +) / E", '_tf8_to_html ( "\\ 1"), $ data); } Function _utf8_to_html ($ data) {$ ret = 0; Foreach ($ str =) ($ ($ data {0})% 252% 248% 240% 224% 192) + 128) Substr ($ data, 1)))) $ k = & gt; $ V) $ ret + = (ord ($ v)% 128) * Pau (64, $ k); Return "& # $ ret;";

I have a SWT FileDialog (style: SWT.OPEN) with several filters with many file extensions I want to include a "all known format" filter with which the application recognizes. This list is very long and will not fit on the screen. On Mac, the File Dialog filter combo box gives the width of the broad filter string. Control is easily usable because the string is very extensive to fit on-screen and the text is centered so that you can not read the filter description in the beginning.
I can hide the file extension in the FileDialog filter combo box has been dragged on-screen but still connects the extension with the filter? Anyone have alternative suggestions?
Screenshot of problem
< P>
FileDialog requires that you provide a list of details and a list of extensions to define a set of filters. I ignored the fact that my code added a description and extension list to create a more descriptive label. It was at that time when the number of supported file types was small. The answer is to provide a situation where the extension list is not associated with "all known formats". It's embarrassing ...

BufferedInputStream में = नया BufferedInputStream (socket.getInputStream ()); कोशिश (DataInputStream d = नया DataInputStream (में)) {स्ट्रिंग फाइलनाम = डी.्रेडूट एफ (); Files.copy (डी, पथ .get (फ़ाइलनाम)); }
I have some functions that change a user input as a binary number in the form of a string. This is part of a basic 'assembler' program on which I am working. Here is my code:
Function GenerNinBurnerNumber (InputWall) // only works for hash! {Var number; If (hash (input value) in it! = -1) {number = getNumberFromString (inputValue); } Return Decimal Tokyo (number); } Function hash (number) // functioning! {Var n = number.indexOf ('#'); Return n; } Function getNumberFromString (mixed input) // work! {Return (mixed input. Location ('#', '')); } Function Decimal Tutorial (Decimal) // Working! {Decimal = parsih (decimal); Return decimal Two string (2); } For example, if a user enters the value of '5', then the function returns NaN - although if they specify that # 5 works - 101 returns. I'm new to programming and javascript, if someone could point me in the right direction which would be great. Thanks!
if any #
function Generate BinaryNumber (inputValue) // only works for hash! {Var number; // if the number is not set (hash (input value) in it! = -1) {// the number is set here, but only if if statement is true number = getNumberFromString (inputValue); } // If, then hash was false, the number is undefined decimal decimal number (number); }
You only want to say var number = inputValue when you declare it
As a side note, Your paraset does not look like a radius argument (something like parseInt (decimal, 10) ) otherwise it will input as hex digits such as "010" and it will Will parse incorrectly.
मेरा एक्सएमएल डेटा पृष्ठ पर प्रदर्शित किया जा रहा है, लेकिन जब मैं ड्रॉप डाउन का इस्तेमाल करता हूं, तो यह चुनने के लिए कि मैं कौन-से विशिष्ट चयन करना चाहता हूं, यह कुछ भी बदलेगा नहीं। मुझे नहीं पता कि मैं क्या कर रहा हूं।
मेरा एक्सएमएल टैग सभी सही हैं, मैंने इसे सुनिश्चित कर लिया है।
आपके द्वारा पोस्ट किए गए कोड में, मुझे नहीं पता है कि जब आप ड्रॉप डाउन में कुछ चुनते हैं, तो आप इसे बदलने के लिए कहां करते हैं। आप इसे क्या करने की उम्मीद करते हैं? आपको ड्रॉप डाउन में एक बदलाव श्रोता जोड़ने की आवश्यकता होगी, और यह बताएं कि जब यह बदल जाएगा, तो ऐसा क्या होगा ...
$ ("# ड्रॉपडाउन")। परिवर्तन (फ़ंक्शन () {// डॉप डाउन बदल जाने पर आप क्या करना चाहते हैं। // आप इस तरह ड्रॉप डाउन का पाठ प्राप्त कर सकते हैं ... var चयनित = $ ("# ड्रॉपडाउन विकल्प: चयनित")। पाठ ( );});
इसके अलावा, एक साइड नोट के रूप में, अपने कोड को रिफैक्टर करने का प्रयास करें ताकि आप केवल एक बार AJAX कॉल कर सकें, और दोनों के लिए आउटपुट का उपयोग करें। ऐसा लगता है कि आपके समान सेवा के लिए दो बार उसी कॉलिंग को बुला रहे हैं जो बिना किसी कारण के अतिरिक्त कार्य है।
I know how to print the line of the first occurrence of the string, but I'm not sure how to print Events have to do To print the first occurrence of my string I have used
grep ", 1," my_course
I think all events Something looks like print:
while grep (the next line of the file), 1, "my_course
I'm not sure how to To do this while loop though. How can I test if the file is the next line.
EDIT: Sorry, I think grep only matches the first event. When I ran away, it only corresponds to 1 line. I did not know that only 1 line matched
In addition to this, the bonus question is if someone wants to answer ... if all the lines in my file (Mycorsy) "number, name, Credit hours, grades ", how do I get all the grades in the file and store it in an array?
I The pattern matrix can make the piece as pure Python:
& gt; & Gt; & Gt; R = (1,4)> gt; & Gt; & Gt; S = (2,5)> gt; & Gt; & Gt; [L [L] [R] [R] [1]] [[2, 3, 4], [2, 3, 4], [2, 3, 4]] < P> Which is not the easiest thing to read and is not the most efficient: -)
Question: Is there an easy way to piece an arbitrary matrix (pure Python) in the form of pure matrix? "post-text" itemprop = "text">
[7] [7]: [[2, 3, 4], [2, 3, 4], [2] 2] list :
By defining the subclass of the square you can copy the syntax of NumPy:
List (list): def __init __ (self, * args): list .__ init __ (auto, * args) def __getitem __ (self, items): try: return list .__ getitem __ (auto, item) Excluding TypeError: Rows, Cols = item row [row] [for rows] [row]] lol = LL (for category in the list (category (10)) (10)] Print (y G [1: 4, 2: 5])
also yield
[[2, 3, 4], [2, 3, 4] , [2, 3, 4]]
Lol will not win any speed test using the subclass: [85] In: [time] [row] [2: 5] [1: 4] for the line in the X 1000000 loops, the best 3: 538 in the NS loop [82]:% Timeit lol [1: 4, 2: 5] 100000 loops, the best 3 : 3.07 per loop per
But speed is not everything - Sometimes readability is even more important.
I should know if property is property or not, I just like the examples, if I < P> is an example object
var foo = {"bar": {"foobar": {"barfoo": 1}}}
and I have to check whether barfoo is present, but first I have to check that there are all other properties, because it can happen or not if any other function is running. I can not really reduce the level of this structure, so there is no alternative.
Currently I am doing something like this:
var d = Foo; If (D) {d = d.bar; If (d) {d = d. Fobar; If (D) {d = d.barfoo; If (d) {console.log (d); More Strong Solution: Check
