  • error in running recursion

    - by GOsha
    if running function returns server misconfiguration error function build_path($cid) { $result = array(); $DB = new MySQLTable; $DB->TblName = 'shop_categories'; $where['cat_id']['='] = $DB->CleanQuest($cid); $res = $DB->Select('cat_id,cat_name,cat_parent', $where); if($res !== 'false') { $pid = mysql_fetch_array($res); if($pid['cat_parent'] !== 0) { Echo $pid['cat_parent']; build_path($pid['cat_parent']); } else { Echo $pid['cat_id']; return true; } } return false; } I can't find an error here. Please help. Sorry for disturbing you all. The trouble was in comparison 'if($pid['cat_parent'] !== 0)': $pid['cat_parent'] was a string with int(0) Can i build this function to store full path without using GLOBALS and SESSION vars?

  • Breaking from for loop in MATLAB GUI

    - by Nick
    I have a for loop in the opening function of a GUI in MATLAB and I'm trying to use a callback button to break the loop. I'm new to MATLAB. Here's the code I have: %In the opening function of the GUI handles.stop_now = 0; for i=1:inf if handles.stop_now==1 break; end end % Executes on button press function pushbutton_Callback(hObject, eventdata, handles) % hObject handle to end_segmenting_button (see GCBO) % eventdata reserved - to be defined in a future version of MATLAB % handles structure with handles and user data (see GUIDATA) handles.stop_now=1; guidata(hObject, handles); For some reason, despite defining the variables with handles, the loop doesn't break upon pressing the button. Anyone know what's going on? Thanks.

  • Two buttons in a form, Both called

    - by coffeeaddict
    Here's my ASP.NET form. When I click one button it calls both jQuery functions. It's probably a rudimentary HTML question but I'm not sure why: <form id="form1" runat="server"> <div id="testDialog"> </div> <p><input type="button" id="invoke1" value="test 1" /></p> <input type="button" id="invoke2" value="test 2" /> </form> <script type="text/javascript"> $(function() { $("input:invoke1").click(function(){ showSomething("testDialog"); }); $("input:invoke2").click(function(){ showSomething2("test.aspx", options); }); }); </script>

  • A good way to look back arbitrary number of items in the Array.Fold in F#

    - by tk
    In the folder function of the Array.Fold operation, i want to look back arbitrary number of items. The only way i can figure out is like this. let aFolder (dataArray, curIdx, result) (dataItem) = let N = numItemsToLookBack(result, dataItem) let recentNitems = dataArray.[curIdx - n .. curIdx - 1] let result = aCalc(result, dataItem, recentNitems ) dataArray, curIdx + 1, result myDataArray | Array.fold aFolder (myDataArray, 0, initResult) As you can see, I passed the whole dataArray and index to the folder function to get the "recentNitems". But this way allows the folder function to access not only preceding data, but also the following data. Is there a better (or more functional) way?

  • Why isn't this infinite recursion? How does default variable initialization work in VB.NET?

    - by froadie
    I just made an interesting mistake in my code: Dim endColumn As Integer = startColumn + endColumn - 1 The code was actually supposed to be: Dim endColumn As Integer = startColumn + numColumns - 1 The interesting thing is, I would think that this code should be recursive and loop indefinitely, as the initialization of endColumn sort of calls itself. However, it seems that the code just treats the uninitialized variable as a 0 and so I get startColumn + 0 - 1. What is happening here behind the scenes? When does a variable get assigned a default value?

    I want to know whether I can calculate the running time for each thread. I implement a multithread program in C++ using pthread. As we know, each thread will compete the CPU. Can I use clock() function to calculate the actual number of CPU clocks each thread consumes? my program looks like: Class Thread () { Start(); Run(); Computing(); }; Start() is to start multiple threads. Then each thread will run Computing function to do something. My question is how I can calculate the running time of each thread for Computing function

  • C - memset segfault for statically allocated char array

    - by user1327031
    I get a segfault when trying to memset an array of chars that was allocated statically, but not for an array of the same length that was allocated using malloc. variable definitions: //static char inBuff[IN_BUFF_LEN]; //dynamic char * inBuffD; function call: //static, cast used because char** != char (*) [n] serverInit(portNum, (char**) &inBuff, &serv_addr, &sockfd) //dynamic serverInit(portNum, &inBuffD, &serv_addr, &sockfd) use within the function: memset(*inBuffAdr, 0, IN_BUFF_LEN); I suspect that my problem is in the difference of the function calls, or to be more precise, my incomplete understanding of the "char** != char (*) [n]" situation. But I have been banging at this for too long and can't see the forest from the trees so any hints and advice would be very appreciated.

  • Better alternatives to know whether a control is valid in javascript?

    - by Anthony
    I want to know whether a control is valid or not in javascript. Is there a direct client side API available in Asp.Net which can tell me whether a control is valid or not? Eg. If I have 2 validators attached to a textbox, I need a function that can tell me whether the textbox is valid or not. If even 1 validator is not valid then it should return false. I can't seem to find a function that can give me this. Here is a little helper that I wrote which does the job but is inefficient: function isControlValid(control) { for (i = 0; i < Page_Validators.length; i++) { var validator = Page_Validators[i]; var controlId = validator.controltovalidate; if ($(control).attr('id') == controlId && validator.isvalid == false) { return false; } } return true; } Anybody has any better alternatives?

  • MVC partial page update

    - by GB
    Hello, I have an MVC project where I have a form with fields a user can enter and save. On that same page I have a table which shows a brief listing of information that the user just saved. The problem I am having is trying to update only the table after a save and not an entire page refresh. Is this possible in jquery or MVC? If so does anyone have an example. Here is what the action in the controller looks like: public ActionResult RefreshList() { string _employeeID = Request.QueryString["empIDSearch"]; this.ViewData["coursehistorylist"] = _service.ListCoursesByEmpID(_employeeID); return View("CourseHistoryList"); } The function in the view: (and this is where I'm confused on how to update only the table) $.ajax({ url: "/Home/RefreshList", type: "POST", success: function(result) { alert("got here"); }, error: function(xhr, ajaxOptions, thrownError) { alert(xhr.status + " " + thrownError + " " + ajaxOptions); } }); Thanks.

  • Is there any injection vunerability in the body of an email?

    - by Brett
    Hey guys..... AFAIK there is only a vulnerability within the HEADERS of an email when using user data correct? I am using the below function to sanitize my data, however I have some textarea fields on the page & hence these may contain linebreaks.. so was wondering if that user data is only going to be put in the body of the email, can it not bother with being sanitized - apart from stripping html of course? Here is the function: function is_injected($str) { $injections = array('(\n+)', '(\r+)', '(\t+)', '(%0A+)', '(%0D+)', '(%08+)', '(%09+)' ); $inject = join('|', $injections); $inject = "/$inject/i"; if (preg_match($inject,$str)) { return true; } else { return false; } } As a side note, surprised there wasn't currently a tag for mail-injection / email-injection. Thanks!

  • Javascript Autocomplete Text

    - by WPS
    Hi All, I need to implement an autocomplete text field using JavaScript and JSF. When the user types some character in a text field, I need to make an AJAX request and get the values based on the values entered. I've an input text field, on "keyup" I'm triggering a function which submits the value to the server side. var timeoutid = 0; function intitiateTypeAhead(){ clearTimeout(timeoutid); if (document.getElementById("inputText").value.length >= 2) { timeoutid = setTimeout('clickButton', 500); } return false; } function clickButton(){ //submits the value to the server } <h:inputText id="inputText" onkeyup="intitiateTypeAhead()"></h:inputText> This works properly, but certain times the request is made for each character entered by the user. I'm not sure if there is anything wrong with the implementation. Can someone please help me to fix this?

  • In OCaml, how can I create an out_channel which writes to a string/buffer instead of a file on disk

    - by Tianyi Cui
    I have a function of type in_channel -> out_channel -> unit which will output something to an out_channel. Now I'd like to get its output as a string. Creating temporary files to write and read it back seems ugly, so how can I do that? Is there any other methods to create out_channel besides Pervasives.open_out family? Actually, this function implemented a repl. What I really need is to test it programmatically, so I'd like to first wrap it to a function of type string -> string. For creating the in_channel, it seems I can use Scanf.Scanning.from_string, but I don't know how to create the out_channel parameter.

  • PHP inheriting/extending a particular instance of an Object

    - by delta9
    Is there any way to force PHP to extend an existing/particular (and for that matter, already instantiated) instance of an object? This imaginary code should explain what I am wondering: class Base { public $var; function __construct($var){ $this->var = $name; } } class Extender extends Base { function __construct($parent) { parent = $parent; } } $base = new Base('yay!'); $extender = new Extender($base); echo 'Extended base var value: '.$extender->var.'<br/>'; Output (would be): Extended base var value: yay! To be clear, I am wanting to instantiate an object that extends a PARTICULAR INSTANCE of another object, one that has already been instantiated. I am aware that I can pass a reference to an object to another object (via it's constructor function) and then add it as a property of the receiving object, I'm wondering if there is a real way to do this?

  • Adding an integer onto an array

    - by Ohmnastrum
    I'm trying to add random numbers onto the end of this array when ever I call this function. I've narrowed it down to just this so far. when ever I check to see if anything is in the array it says 0. So now i'm quite stumped. I'm thinking that MutableArray releases the contents of it before I ever get to use them. problem is I don't know what to use. A button calls the function and pretty much everything else is taken care of its just this portion inside the function. NSMutableArray * choices; -(void) doSomething { int r = arc4random() % 4; //The problem... [choices addObject:[NSNumber numberWithInt:r]]; int anInt = [[choices objectAtIndex:1] integerValue]; NSLog(@"%d", anInt); //I'm getting nothing no matter what I do. //some type of loop that goes through the array and displays each element //after it gets added }

  • Is there a way to read 10000 lines from a file in python?

    - by windsound
    I am relatively new in python, was working on C a lot. Since I was seeing so many new functions in python that I do not know, I was wondering if there is a function that can request 10000 lines from a file in python. Something like this is what I expect if that kind of function exist: lines = get_10000_lines(file_pointer) Did python have a build-in function or is there any module that I can download for this? If not, how do I do this to be easiest way. I need to analyze a huge file so I want to read 10000 lines and analyze per time to save memory. Thanks for helping!
