  • How to create newline in a rebol block ?

    - by Rebol Tutorial
    let's say I have a config.txt which contains: "param11" "param12" "param21" "param22" I'll load it in memory with config: load %config.txt I can save it back with save %config.txt config So far so good. Now the problem occurs for me when I want to add "param31" "param32" I have tried append config reduce [newline "param31" "param32"] save %config.txt config But that doesn't give the expected result "param11" "param12" "param21" "param22" "param31" "param32" but this instead "param11" "param12" "param21" "param22" #"^/" "param31" "param32" So how to ?

  • block write access to table from an application in mysql

    - by hoberion
    Hello, We have a CMS plugin that writes statistics to 1 table, this creates performance issues on the entire platform. We decided to use another statistics plugin which can connect to a different database server (the first plugin couldn't!) however we need parts of the first plugin. I want to lock the statistics table to prevent misusage (not allowed to drop it by the developer) So I was wondering if a lock table could do this or if I can implement some sort of read only table

    Given the Thread class with it current method. Now inside a test, I want to do this: def test_alter_current_thread Thread.current = a_stubbed_method # do something that involve the work of Thread.current Thread.current = default_thread_current end Basically, I want to alter the method of a class inside a test method and recover it after that.

  • Set reference = null in finally block?

    - by deamon
    A colleague of mine sets reference to null in finally blocks. I think this is nonsense. public Something getSomething() { JDBCConnection jdbc=null; try { jdbc=JDBCManager.getConnection(JDBCTypes.MYSQL); } finally { JDBCManager.free(jdbc); jdbc=null; // <-- Useful or not? } } What do you think of it?

  • Creating a "Universities Attended" Profile field/block (Drupal)

    - by Frank0051
    Interesting question for everyone. So I have am thinking of adding a "university attended" field to the profile page of members in Drupal. I guess I am trying to figure out the best way to go about it. I was originally thinking of a text field, but than I thought you could get multiple instances of of university names, making it hard to sort people by school (ie. UF, University of Florida, Florida, U of F, etc). I then began to think about creating a drop down, but I wasn't quite sure where I could get a listing of all the schools. Perhaps I could find a database population that a site like LinkedIn or Facebook uses. Then I thought of what happens when someone has attended multiple schools, how would I account for that? So, I guess I wanted to pose the question of how would you go about adding a University(ies) attended field to profile pages if you had to design a site to do so?

  • Strange behaviour when simply adding strings in Lazarus - FreePascal

    - by linkcharger
    The program has several "encryption" algorithms. This one should blockwise reverse the input. "He|ll|o " becomes "o |ll|He" (block length of 2). I add two strings, in this case appending the result string to the current "block" string and making that the result. When I add the result first and then the block it works fine and gives me back the original string. But when i try to reverse the order it just gives me the the last "block". Several other functions that are used for "rotation" are above. //amount of blocks function amBl(i1:integer;i2:integer):integer; begin if (i1 mod i2) <> 0 then result := (i1 div i2) else result := (i1 div i2) - 1; end; //calculation of block length function calcBl(keyStr:string):integer; var i:integer; begin result := 0; for i := 1 to Length(keyStr) do begin result := (result + ord(keyStr[i])) mod 5; result := result + 2; end; end; //desperate try to add strings function append(s1,s2:string):string; begin insert(s2,s1,Length(s1)+1); result := s1; end; function rotation(inStr,keyStr:string):string; var //array of chars -> string block,temp:string; //position in block variable posB:integer; //block length and block count variable bl, bc:integer; //null character as placeholder n : ansiChar; begin //calculating block length 2..6 bl := calcBl(keyStr); setLength(block,bl); result := ''; temp := ''; {n := #00;} for bc := 0 to amBl(Length(inStr),bl) do begin //filling block with chars starting from back of virtual block (in inStr) for posB := 1 to bl do begin block[posB] := inStr[bc * bl + posB]; {if inStr[bc * bl + posB] = ' ' then block[posB] := n;} end; //adding the block in front of the existing result string temp := result; result := block + temp; //result := append(block,temp); //result := concat(block,temp); end; end; (full code http://pastebin.com/6Uarerhk) After all the loops "result" has the right value, but in the last step (between "result := block + temp" and the "end;" of the function) "block" replaces the content of "result" with itself completely, it doesn't add result at the end anymore. And as you can see I even used a temp variable to try to work around that.. doesnt change anything though.

  • Drupal: Views: grouping relationship in block list

    - by Ronn
    I have a question about views, specifically about grouping a relationship. I have a "partner" node that has many "docs", I want to list the name of the "partner" along with its corresponding "docs" below. I have the relationship set up correctly(I think) but can't figure out how or where to group it correctly. I get this: partner name 1 - doc name 1 partner name 1 - doc name 2 partner name 1 - doc name 3 partner name 2 - doc name 4 partner name 2 - doc name 5 partner name 3 - doc name 6 but would like this: partner name 1 - doc name 1 - doc name 2 - doc name 3 partner name 2 - doc name 4 - doc name 5 - doc name 6

  • External Javascript file fails to receive variables from previous javascript block

    - by Franc
    I've been searching the net for several hours and can't find an answer in the whole "external js file"-jungle. I hope you guys can help! In short: My external javascript file doesn't seem to get the variables which I defined in the main.php file.. On main.php I define php variables and "transform" them into javascript variables <head>... <script type="text/javascript"> var phpmain_img = <?php echo json_encode($main_img); ?>; var phpvar1_large = <?php echo json_encode($var1_large); ?>; var phpvar2_large = <?php echo json_encode($var2_large); ?>; var phpvar3_large = <?php echo json_encode($var3_large); ?>; var phpvar4_large = <?php echo json_encode($var4_large); ?>; </script> ... <script language="javascript" type="text/javascript" src="/wshop/ext.js"></script> </head> In my ext.js file I want to process those variables. In the ext.js file I defined a the function swapImage() that will be used back in the main PHP: var imgArray = new Array( phpmain_img, phpvar1_large, phpvar2_large, phpvar3_large ); function swapImage(imgID) { var theImage = document.getElementById('theImage'); var newImg; newImg = imgArray[imgID]; theImage.src = newImg; } function preloadImages() { for(var i = 0; i < imgArray.length; i++) { var tmpImg = new Image; tmpImg.src = imgArray[i]; } } Result: The swapImage() in the main.php... doesnt work <div id="image"> <img id="theImage" src="<?=$main_img; ?>" alt="" /> </div> <div id="thumbs"> <?php echo "<img src=\"<$main_img_small\" alt=\"\" onmouseover=\"swapImage(0);\">"; echo "<img src=\"$var1_small\" alt=\"\" onmouseover=\"swapImage(1);\">"; echo "<img src=\"$var2_small\" alt=\"\" onmouseover=\"swapImage(2);\">"; echo "<img src=\"$var3_small\" alt=\"\" onmouseover=\"swapImage(3);\">"; ?> <br /> </div> Any help is greatly appreciated! UPDATE: I don't get a specific error, the swapImage functions doesn't work at mouseover. However, I tried to output the variables with e.g. document.write(phpimg_main) but nothing appears which makes me believe that there's something wrong with the handing over of the variables... here's the source code browser output `<html> <head> <link href="../demo.css" rel="stylesheet" type="text/css" /> <style type="text/css"> .... </style> <script type="text/javascript"> var phpmain_img = {"0":"http:\/\/path\/to\/main\/image.jpg"}; var phpvar1_large = {"0":"http:\/\/path\/to\/image1.jpg"}; var phpvar2_large = {"0":"http:\/\/path\/to\/image2.jpg"}; var phpvar3_large = null; var phpvar4_large = null; </script> <script language="javascript" type="text/javascript" src="/wshop/ext.js"></script> </head> <body onload="preloadImages()"> <div id="image"> <img id="theImage" src="http://path-to-main-image.jpg" alt="" /> </div> <div id="thumbs"> <img src="http://path-to-main-image.jpg" alt="" onmouseover="swapImage(0);"><img src="http://path-to-image1.jpg" alt="" onmouseover="swapImage(1);"><img src="http://path-to-image2.jpg" alt="" onmouseover="swapImage(2);"> <br /> </div> </body> `

  • divide the image into 3*3 blocks

    - by Jayanth Silesh
    I have a matrix that does not happen to have dimensions that are multiples of 3 or it might. How can we divide the entire image into blocks of 3*3 matrices. (Can ignore the last ones which does not come under the 3*3 multiples. Also, the 3*3 matrices can be be saved in arrays. a=3; b=3; %window size x=size(f,1)/a; y=size(f,2)/b; %f is the original image m=a*ones(1,x); n=b*ones(1,y); I=mat2cell(f,m,n);

  • How to drop a sortable block?

    - by Pentium10
    I have a list which is reordered using sortable. I defined a trash can div, and I want to achieve that when the blocks are dropped on this div to get deleted. So far I can't seam to fine the way to fire the drop event, when I release the item gets back to his previous position. I have this code: $(document).ready(function() { var order = null; $("#order-list").load(location.href+" #order-list>*",""); $("#order-list").sortable({ handle : '.handle', update : function (e, ui) { order = $(this).sortable('serialize'); $("#info").load("process-sortable.php?"+order); } }); }); and $("#trashcan").droppable({ drop: function(event, ui) { draggedid = ui.draggable.attr('id'); alert(draggedid); // doesn't fire $.get("process-add-subcat.php", { "action" : "delete_subcategory", "draggedid": draggedid }, function(data){ }); } });

  • How to parse multiple dates from a block of text in Python (or another language)

    - by mlissner
    I have a string that has several date values in it, and I want to parse them all out. The string is natural language, so the best thing I've found so far is dateutil. Unfortunately, if a string has multiple date values in it, dateutil throws an error: >>> s = "I like peas on 2011-04-23, and I also like them on easter and my birthday, the 29th of July, 1928" >>> parse(s, fuzzy=True) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/pymodules/python2.7/dateutil/parser.py", line 697, in parse return DEFAULTPARSER.parse(timestr, **kwargs) File "/usr/lib/pymodules/python2.7/dateutil/parser.py", line 303, in parse raise ValueError, "unknown string format" ValueError: unknown string format Any thoughts on how to parse all dates from a long string? Ideally, a list would be created, but I can handle that myself if I need to. I'm using Python, but at this point, other languages are probably OK, if they get the job done. PS - I guess I could recursively split the input file in the middle and try, try again until it works, but it's a hell of a hack.

  • jquery .blur for entire block of HTML

    - by Stacey
    I have an HTML item for a 'drop down menu', structured like this... <li class="ui-dropdown-list" > <a href="#">Right Drop Down Menu</a> <ul> <li><a href="#">Item</a></li> <li><a href="#">Item</a></li> <li><a href="#">Item</a></li> </ul> </li> Using jQuery to make this a dropdown list, with the following code. jQuery.fn.dropdown = function () { var defaults = { button: null, menu: null, visible: false }; var options = $.extend(defaults, options); return this.each(function () { options.button = $(this); options.menu = $(this).find("ul"); // when the parent is clicked, determine whether dropdown needs to occur options.button.click(function () { options.visible ? lift(options.menu) : drop(options.menu); options.visible = !options.visible; }); // drop the menu down so that it can be seen. function drop(e) { options.button.addClass("open"); options.menu.show(); } // lift the menu up, hiding it from view. function lift(e) { options.menu.hide(); options.button.removeClass('open'); } }); }; I am trying to wire it up so that if the user clicks anywhere outside of the menu, it will collapse it. This is proving much more difficult than I anticipated; even trying to use page level events. Any suggestions? The menu itself never really 'receives' focus, so using .blur doesn't seem to be suiting the purpose.

  • Understanding c++ block of code

    - by kotoko
    I was given a c++ main and have to code it so it works. I am having some trouble understanding the code as I am a bit new to cpp. Here is the code int main(int argc, char *argv[]) { Class::setAtribute("string"); Class(Class::CONSTANT) << "starting up..."; } Some questions: How can the first line work with no variables? Is it static? The second line is really strange for me, what I can make out is a Constructor that takes in a class constante and then prints it out somehow? If someone could explain me this bit of code it would be great! Thanks in advance.

  • Difference in declaring IDisposable member in using block or at using block declaration?

  • Block upload of executable images (PHP)

    - by James Simpson
    It has come to my attention that a user has been trying to create an exploit through avatar image uploads. This was discovered when a user reported to me that they were getting a notice from their Norton Anti-virus saying "HTTP Suspicious Executable Image Download." This warning was referencing the user's avatar image. I don't think they had actually achieved anything in the way of stealing information or anything like that, but I assume it could be possible if the hole is left open long enough. I use PHP to upload the image files, and I check if the file being uploaded is a png, jpg, or gif.

  • Lua Tables w/ Changing Variables - Mental Block

    - by bottles
    I always assumed that changing the value of k from "x" to 20 would eliminate "x". So why then in this example are we able to go back and reference "x"? a = {} k = "x" a[k] = 10 print(a[k]) ---> Returns 10 print(a["x"]) ---> Returns 10 a[20] = "great" k = 20 print(a[k]) ---> "great" a["x"] = a["x"] + 1 print(a["x"]) --> 11 Why does that last print command work, and return 11? I thought we set k = 20. Why is "x" even in the picture?
