    यह मेरा PHP कोड है: <पूर्व> & lt; html & gt; & Lt; शीर्ष & gt; & Lt; title & gt; एसक्यूएल डीबी प्रबंधन & lt; / title & gt; & Lt; / head & gt; & LT; बॉडी & gt; & Lt; h1 & gt; mysqladmin & lt; / h1 & gt; & LT; तालिका & gt; & LT; टीआर & gt; & Lt; th & gt; & lt;! - शीर्षक 1 - & gt; & lt; / th & gt; & Lt; th & gt; & lt;! - हेडिंग 2 - & gt; & lt; / th & gt; & Lt; th & gt; & lt;! - इसे खाली छोड़ें - & gt; & lt; / th & gt; & Lt; / टीआर & gt; & Lt;? Php $ db_host = "mysql.freehostingnoads.net"; $ Db_username = ""; $ Db_password = ""; $ db_name = ""; $ db_table = ""; $ db = mysqli_connect ($ db_host, $ db_username, $ db_password, $ db_name); अगर (mysqli_connect_errno ()) (मर ("MySQL से जुड़ने में असफल:"। Mysql_connect_error ());} $ content = mysqli_query ($ db, "SELECT * FROM"। $ Db_table); जबकि ($ line = mysqli_fetch_array ($ सामग्री)) {गूंज ("& lt; tr & gt;"); गूंज ("& lt; td & gt;"। $ पंक्ति ['सी 1']। "& lt; / td & gt;"); गूंज ("& lt; td & gt;"। $ पंक्ति ['सी 2']। "& lt; / td & gt;"); #delete बटन गूंज ("& lt; td & gt; & lt; form action = 'del.php' method = 'GET' & gt; & lt; इनपुट प्रकार = 'टेक्स्ट' नाम = 'c1' मान = '"। $ Line [' c1 ']। "' / & Gt; & lt; input type = 'text' name = 'c2' मान = ''। $ Line ['c2']। '' / & Gt; & lt; इनपुट प्रकार = 'बटन' मान = ' DEL '/ & gt; & lt; / form & gt; & lt; / td & gt; "); गूंज ( "& lt; / टीआर & gt;"); }? & Gt; & Lt; / body & gt; & Lt; / html & gt;

    और बस & lt; head & gt; को पढ़ना छोड़ दें, यह मुझे मिली चेतावनी है:

    चेतावनी: mysqli_fetch_array ()

    मैं खोज की है लेकिन जवाब नहीं मिल सकता पैरामीटर 1 mysqli_result होने की उम्मीद है, बूलीयन /home/u273577101/public_html/index.php में लाइन 23 पर दिया

    यहां समस्या क्या है?
    कोई कनेक्शन त्रुटि नहीं है, मुझे लगता है। यह मुझे कनेक्ट करने के बारे में कोई त्रुटि संदेश देने में प्रतीत नहीं होता।

    mysqli_query बूलीयन FALSE लौट रहा है क्योंकि आपका $ db_table वेरिएबल एक रिक्त स्ट्रिंग पर सेट है और इसलिए परिणामस्वरूप आप जो क्वेरी दे रहे हैं वह अमान्य है।

    आप बस एक वैध तालिका नाम के लिए $ db_table चर सेट करना होगा।

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...

I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

C# code to obtain Maximum SQL Server 2012 Write Performance -

I want to know whether we are already performing the fastest SQL EEE for our application. We have created a sample application that performs a bulkopy operation in the local SQL Server database. Bulk CoP writes 100,000 rows of data from the dataTable in the Operation Memory. There is no index in the table inserted. The reason for this is that we want to achieve the maximum write speed of SQL Server only. The schema of this table that we are putting in: create table [dbo] [history score values] [[history paramatid] [bininata] null, [sourstimestamp] ] [Datetime2] (7) no tap, [architaimstamp] [datetime2] (7) no tap, [valutas] [int] tap, [arcastastas] [integer] no, zero, [integer] [int] Double walled] [float] spare null, [stringvalue] [varchare] (100) special null, [ennomedetext] [courtesy] (100) [Primary] We measure performance from our C # code on [Pure null, [anumumericvalue] [int] spare noal, [enumerative value] [varchar] (256) special noise) .
