  • SQL join produces one result only

    - by Rami
    Can anyone please tell me why this result is generation only one results? taking in mind that everything is set right and the three tables are populated correctly, i took out the group_concat and it worked but of course with a php undefined index error! SELECT `songs`.`song_name`, `songs`.`add_date`, `songs`.`song_id`, `songs`.`song_picture`, group_concat(DISTINCT artists.artist_name) as artist_name FROM (`songs`) JOIN `mtm_songs_artists` ON `songs`.`song_id` = `mtm_songs_artists`.`song_id` JOIN `artists` ON `artists`.`artist_id` = `mtm_songs_artists`.`artist_id` ORDER BY `songs`.`song_id` DESC LIMIT 10 so i'm guessing it's something related to group_concat. best regards, Rami

  • What data formats does PowerShell most easily read ?

    - by Jim
    I'm trying to use PowerShell with SharePoint. I'd like my PowerShell scripts to load my SharePoint farm configuration from files rather than either hard coding the configuration in the scripts, or having to pass in the same parameters each time. This the kind of information I need to store. WebFrontEnds: Web1, Web2, Web3 CentralAdmin: Central1 Index: Web1 ContentWebApps: http://user1, http://user2 Does PowerShell easily load this data from CSV, XML, or other formats?

  • Where are Kohana config files?

    - by elmonty
    I've just installed Kohana 3.0.4.2 and I have run the index.php file successfully. According to the documentation, the next step is to edit the config files in the application/config folder. I have that folder but there are no files in it! I downloaded the package again to make sure it wasn't corrupted, but the same problem exists. Why is the application/config folder empty?

  • Phonegap web view thinks device screen taller than it is - results in offscreen tabbar

    - by Stin
    I have a jQTouch application loaded via server, so all I need to do is display the webpage full screen in PhoneGap for a faux-Native app. Unfortunatley each solution I've tried in PhoneGap has an issue: it thinks the screen size is taller than it is. This resuls in the tabbar that is pinned to the bottom being permantly offscreen and there fore unusable. You should be able to recreate this with my code below and going to the iTabbar online demo. Any thoughts on how to correct this issue? For background, going to the app page in iOS safari works fine, as well as saving the page to the home screen. In both cases the webview stops at the bottom of the screen and the tabbar is therefore viewable. Also, I'm using build.phonegap.com to compile (I'm not compiling locally) I've tried two methods: load the childBrowser plugin and call up the page (with navbar hidden via options) set the following config.xml parameter to prevent phonegap from switching to Safari, and then just load the link (preferable as it's cleaner in my mind. I've pasted my index.html and config.xml below) Details on the config.xml paramater: Open all links in WebView stay-in-webview with values true or false example: <preference name="stay-in-webview" value="true" /> if set to true, all links (even with target set to blank) will open in the app's webview only use this preference if you want pages from your server to take over your entire app default is false (Source: https://build.phonegap.com/docs/config-xml) my index.html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-type" content="text/html;charset=utf-8"> <title>MyApp</title> <script src="phonegap.js"></script> </head> <body> <p><a href="http://www.itabbar.com/itabbar/demo.html#home">Launch iTabbar</a></p> </body> </html> my config.xml: <?xml version="1.0" encoding="UTF-8" ?> <widget xmlns = "http://www.w3.org/ns/widgets" xmlns:gap = "http://phonegap.com/ns/1.0" id = "com.phonegap.myapp" versionCode="10" version = "1.0.0"> <!-- versionCode is optional and Android only --> <name>MyApp</name> <description> My app is... </description> <author href="https://myurl.com" email="[email protected]"> me </author> <preference name="stay-in-webview" value="true" /> </widget>

  • Accessing ArrayBuffer from PHP $_POST after xmlHTTPrequest send()

    - by Dan
    I'm following the tuitions on XMLHttpRequest 2 from : https://developer.mozilla.org/en/DOM/XMLHttpRequest/Sending_and_Receiving_Binary_Data and http://www.html5rocks.com/en/tutorials/file/xhr2/#toc-send-arraybuffer They're great tutorials for the client side, and here is a working extract from my script: var imagebuffer = new ArrayBuffer(size); // create the readonly memory buffer var imagedata= new Uint8Array(imagebuffer); // create a view to manipulate data // do some cool stuff with imagedata var exchange=new XMLHttpRequest(); exchange.open("POST",url,true); exchange.send(arraybuffer); So far so good, and I can see from the both client and server control panels that plenty of data is being transferred. Here's my problem: how do I access the ArrayBuffer with PHP at the server? I'm used to the $_POST superglobal wanting parameters passing from a HTML form so it can be accessed as an array but I can't find any reference for how to access this binary array and stick it in my MySQL database.

  • Drawing individual pixels with iphone sdk.

    - by blob8108
    Hi, I've been trying to figure out how to make a powder toy style game on the iPhone. My problem is how to draw pixels to the screen. From what I've read, OpenGL is better for games as it is faster/hardware accelerated, but there is no method to draw pixels directly to the screen. Apparently drawing pixels to an off-screen frame buffer is the way to go, but how do I then pass this to OpenGL? Do I use a texture? (this is assuming I have no previous knowledge of iPhone graphics programming). Thanks!

  • Pruning data for better viewing on loglog graph - Matlab

    - by Geodesic
    Hi Guys, just wondering if anyone has any ideas about an issue I'm having. I have a fair amount of data that needs to be displayed on one graph. Two theoretical lines that are bold and solid are displayed on top, then 10 experimental data sets that converge to these lines are graphed, each using a different identifier (eg the + or o or a square etc). These graphs are on a log scale that goes up to 1e6. The first few decades of the graph (< 1e3) look fine, but as all the datasets converge ( 1e3) it's really difficult to see what data is what. There's over 1000 data points points per decade which I can prune linearly to an extent, but if I do this too much the lower end of the graph will suffer in resolution. What I'd like to do is prune logarithmically, strongest at the high end, working back to 0. My question is: how can I get a logarithmically scaled index vector rather than a linear one? My initial assumption was that as my data is lenear I could just use a linear index to prune, which lead to something like this (but for all decades): //%grab indicies per decade ind12 = find(y >= 1e1 & y <= 1e2); indlow = find(y < 1e2); indhigh = find(y > 1e4); ind23 = find(y >+ 1e2 & y <= 1e3); ind34 = find(y >+ 1e3 & y <= 1e4); //%We want ind12 indexes in this decade, find spacing tot23 = round(length(ind23)/length(ind12)); tot34 = round(length(ind34)/length(ind12)); //%grab ones to keep ind23keep = ind23(1):tot23:ind23(end); ind34keep = ind34(1):tot34:ind34(end); indnew = [indlow' ind23keep ind34keep indhigh']; loglog(x(indnew), y(indnew)); But this causes the prune to behave in a jumpy fashion obviously. Each decade has the number of points that I'd like, but as it's a linear distribution, the points tend to be clumped at the high end of the decade on the log scale. Any ideas on how I can do this?

  • How can I match at the beginning of any line, including the first, with a Perl regex?

    - by JoelFan
    According the the Perl documentation on regexes: By default, the "^" character is guaranteed to match only the beginning of the string ... Embedded newlines will not be matched by "^" ... You may, however, wish to treat a string as a multi-line buffer, such that the "^" will match after any newline within the string ... you can do this by using the /m modifier on the pattern match operator. The "after any newline" part means that it will only match at the beginning of the 2nd and subsequent lines. What if I want to match at the beginning of any line (1st, 2nd, etc.)? EDIT: OK, it seems that the file has BOM information (3 chars) at the beginning and that's what's messing me up. Any way to get ^ to match anyway? EDIT: So in the end it works (as long as there's no BOM), but now it seems that the Perl documentation is wrong, since it says "after any newline"

  • OpenCV to use in memory buffers or file pointers

    - by The Unknown
    The two functions in openCV cvLoadImage and cvSaveImage accept file path's as arguments. For example, when saving a image it's cvSaveImage("/tmp/output.jpg", dstIpl) and it writes on the disk. Is there any way to feed this a buffer already in memory? So instead of a disk write, the output image will be in memory. I would also like to know this for both cvSaveImage and cvLoadImage (read and write to memory buffers). Thanks! My goal is to store the Encoded (jpeg) version of the file in Memory. Same goes to cvLoadImage, I want to load a jpeg that's in memory in to the IplImage format.

  • Included php file calling Javascript function

    - by Illes Peter
    Hi there! Here's the deal. I've got index.php which links to an internal JS file in it's header. index.php then includes another .php file, which outputs this: + add file. addFile() is a Javascript function defined in the external JS file. By doing this nothing happens, the included php does not "see" the JS function. Encapsulating the JS in the included PHP makes it all work. But I don't want to do it that way. Any ideas? EDIT: here's the source <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>Archie</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <link rel="stylesheet" href="/screen.css" type="text/css" media="screen"/> <script src="/lib/js/archie.js" type="text/javascript"></script> </head> <body> ... ... //included php starts here <form action="/lib/course.php" method="post"> <fieldset> <div id="addFileLocation"></div> <a href="#" onClick="addFile()">+ add file</a> <input type="hidden" id="addFileCount" value="0"/> </fieldset> </form> //ends here ... ... </body> </html> and the js: <script type="text/javascript"> //Dynamically add form fields //add file browser function addFile() { var location = document.getElementById('addFileLocation'); var num = document.getElementById('addFileCount'); var newnum = (document.getElementById('addFileCount').value -1)+ 2; num.value = newnum; var newname = 'addFile_'+newnum; var newelement = document.createElement('input'); newelement.setAttribute('name',newname); newelement.setAttribute('type','file'); location.appendChild(newelement); } </script>

    In Notepad++, I can use ctrl + shift + up/down to move the current line up and down. Is there a similar command to this in Vim? I have looked through endless guides, but have found nothing. If there isn't, how could I bind the action to that key combination? Edit: Mykola's answer works for all lines, apart from those at the beginning and end of the buffer. Moving the first line up or the bottom line down deletes the line, and when moving the bottom line up it jumps two spaces initially, like a pawn! Can anyone offer any refinements?
