  • C++ function call routes resolver

    - by Poni
    Hi! I'm looking for a tool that will tell/resolve for every function all the call paths (call it "routes") to it. For example: void deeper(int *pNumber) { *pNumber++; } void gateA(int *pNumber) { deeper(pNumber); } void gateB(int *pNumber) { gateA(pNumber); } void main() { int x = 123; gateA(&x); gateB(&x); } See? I need a tool that will tell me all the routes to deeper(), and more if possible. By saying "more" I mean that it will tell me if the pointer is the same as been provided to the calling function. This will greatly save me time. Thanks!

  • Calling a function when using <button> tag with jQuery Mobile

    - by u2sonderzug
    I already asked a similar question for buttons in tags, but I find that solution doesn't work using tags. So, if I am using a script that references jQuery Mobile I have the following line: <button id="buttonAnswer1" data-inline="true">Click me</button> How would I add a listener for when this button is clicked and lets say call the hello() function? i.e. <button id="buttonAnswer1" data-inline="true">Click me</button> <script> function hello(){ console.log("hello world"); } </script>

  • Automatic conversion between methods and functions in Scala

    - by fikovnik
    I would like to understand the rules when can Scala automatically convert methods into functions. For example, if I have following two methods: def d1(a: Int, b: Int) {} def r[A, B](delegate: (A, B) ? Unit) {} I can do this: r(d1) But, when overloading r it will no longer work: def r[A, B, C](delegate: (A, B, C) ? Unit) {} r(d1) // no longer compiles and I have to explicitly convert method into partially applied function: r(d1 _) Is there any way to accomplish following with the explicit conversion? def r[A, B](delegate: (A, B) ? Unit) {} def r[A, B, C](delegate: (A, B, C) ? Unit) {} def d1(a: Int, b: Int) {} def d2(a: Int, b: Int, c: Int) {} r(d1) // only compiles with r(d1 _) r(d2) // only compiles with r(d2 _) There is somewhat similar question, but it is not fully explained.

  • jquery: animate function problem

    - by Syom
    i start learning jquery just yesterday. i have a div element with some content, and i want to hide it by changing it's height: here is the script <script type="text/javascript"> $(document).ready(function(){ $("#hide").click(function(){ $("#cont").animate({ height: '0' },1500); $("#cont").hide(); }); }); </script> <input type="button" value="hide" id="hide"> <div id="cont"> text here... </div> but it doesn't work, becouse it automaticaly sets display:block to #cont element, so after animation it starts to show. when i try to set display:none to #cont element, it doesn't happen. could you help me? thanks

  • 7 - drupal overriding theme fucntions gettting notices

    - by welovedesign
    So I am overriding a theme function by putting the contents in my template.php module, the problem is that it it throwing up loads of undefined index notices because there are lots of functions that are defined in the module. How can I define these in the template.php file and prevent the notices. Note: I know i can turn them off 'uc_cart_block_content' => array( 'variables' => array( 'help_text' => NULL, 'items' => NULL, 'item_count' => NULL, 'item_text' => NULL, 'total' => NULL, 'summary_links' => NULL, 'collapsed' => TRUE, ), 'file' => 'uc_cart.theme.inc', ),

  • CouchDB: How to change view function via javascript?

    - by osti
    Hello Guys, I am playing around with CouchDB to test if it is "possible" [1] to store scientific data (simulated and experimental raw data + metadata). A big pro is the schema-less approach of CouchDB: we have to be very flexible with the metadata, as the set of parameters changes very often. Up to now I have some code to feed raw data, plots (both as attachments), and hierarchical metadata (as JSON) into CouchDB documents, and have written some prototype Javascript for filtering and showing. But the filtering is done on the client side (a.k.a. browser): The map function simply returns everything. How could I change the (or push a second) map function of a specific _design-document with simple browser-JS? I do not think that a temporary view would yield any performance gain... Thanks for your time and answers. [1]: of course it is possible, but is it also useful? feasible? reasonable?

  • Improve C function performance with cache locality?

    - by Christoper Hans
    I have to find a diagonal difference in a matrix represented as 2d array and the function prototype is int diagonal_diff(int x[512][512]) I have to use a 2d array, and the data is 512x512. This is tested on a SPARC machine: my current timing is 6ms but I need to be under 2ms. Sample data: [3][4][5][9] [2][8][9][4] [6][9][7][3] [5][8][8][2] The difference is: |4-2| + |5-6| + |9-5| + |9-9| + |4-8| + |3-8| = 2 + 1 + 4 + 0 + 4 + 5 = 16 In order to do that, I use the following algorithm: int i,j,result=0; for(i=0; i<4; i++) for(j=0; j<4; j++) result+=abs(array[i][j]-[j][i]); return result; But this algorithm keeps accessing the column, row, column, row, etc which make inefficient use of cache. Is there a way to improve my function?

  • Passing dynamic parameter to a JavaScript function using innerHTML

    - by user958263
    I am having issues passing a dynamic parameter to a JavaScript function using innerHTML. Included below is the current code that I am using: var name = "test"; frm.innerHtml = '<button name="close" id="close" title="Cancel" type="button" onclick="closeTab('+name+');">Return</button>'; When I debug the code of the CloseTab() function, the parameter specified by the name variable is null. I believe there is a problem with the declaration of the value while modifying the innerHTML property. Any help would be greatly appreciated. Thanks

  • Joining two mysql_fetch_arrays

    - by John Harbert
    I am trying to piece two queries together. Below is the code Im using. However the table is splitting up the data. How can I remedy this?

  • Multifunctioning in Javascript

    - by Starx
    The concept is running multiple functions concurrently. The reason is, I have a page which performs various actions through ajax. These actions includes making multiple backups of new files uploaded in the upload directory. But I want this process to be initiated by a moderator. As this is a very lengthy process(might even take hours to complete), it blocks others ajax requests from executing, until this process complete. I want to execute functions along with the previously executed function parallelly. I am using jQuery's Ajax to sent initiate the request.

  • Align a set of elements that are not next to each other in the HTML

    - by user1917727
    I am creating a comparison table where the columns are built as below: <div id = "wrapper"> <div id = "col1"> <div class = "row1"> text lots more text and more text </div> <div class = "row2"> text </div> <div class = "row3"> text </div> </div> <div id = "col2"> <div class = "row1"> text </div> <div class = "row2"> a lot of text </div> <div class = "row3"> text </div> </div> </div> Col1 and col2 are then displayed as an inline-block so they visually sit next to each other on the page. The problem is that the contents of each row may vary. Without setting a min-height of each row, how could i make sure that each row visually lines up with its corresponding row from the other column? I can't think of any way to achieve this in CSS alone. I'm wondering if there's some sneaky jQuery way of achieving this? EDIT: I Can't change the HTML structure. Cheers

  • Converting a macro to an inline function

    - by Rob
    I am using some Qt code that adds a VERIFY macro that looks something like this: #define VERIFY(cond) \ { \ bool ok = cond; \ Q_ASSERT(ok); \ } The code can then use it whilst being certain the condition is actually evaluated, e.g.: Q_ASSERT(callSomeFunction()); // callSomeFunction not evaluated in release builds! VERIFY(callSomeFunction()); // callSomeFunction is always evaluated Disliking macros, I would instead like to turn this into an inline function: inline VERIFY(bool condition) { Q_ASSERT(condition); } However, in release builds I am worried that the compiler would optimise out all calls to this function (as Q_ASSERT wouldn't actually do anything.) I am I worrying unnecessarily or is this likely depending on the optimisation flags/compiler/etc.? I guess I could change it to: inline VERIFY(bool condition) { condition; Q_ASSERT(condition); } But, again, the compiler may be clever enough to ignore the call. Is this inline alternative safe for both debug and release builds?

  • Call a function every hour

    - by user2961971
    I am trying to update information from a weather service on my page. The info should be updated every hour on the hour. How exactly do I go about calling a function on the hour every hour? I kind of had an idea but im not sure of how to actually refine it so it works... What I had in mind was something like creating an if statement, such as: (pseudo code) //get the mins of the current time var mins = datetime.mins(); if(mins == "00"){ function(); }

  • How can I add dynamic text from a different table where primary key is a foreign key to adynamic table being shown?

    - by Jethro Tamares Doble
    I have here a dynamic table named tb_user with column region_id and institute_id and both ids are primary key of another table tb_region (with column region_name and region_id) and tb_institute (column institute_id and institute_name). I wanted to see region_name and institute_name instead of the ids. I've used this php script <?php echo $row_institute['institution_name']; ?> and query to collect data for tb_institute mysql_select_db($database_connection_ched, $connection_ched); $query_institution = "SELECT institute_id, institute_name FROM tb_institute"; $institution = mysql_query($query_institution, $connection_ched) or die(mysql_error()); $row_institution = mysql_fetch_assoc($institution); $totalRows_institution = mysql_num_rows($institution); but it seems not to display the correct name of id. query i used to collect data: mysql_select_db($database_connection_ched, $connection_ched); $query_notification = sprintf("SELECT * FROM tb_user WHERE status = 'inactive' ORDER BY date_register ASC", GetSQLValueString($colname_notification, "text")); $query_limit_notification = sprintf("%s LIMIT %d, %d", $query_notification, $startRow_notification, $maxRows_notification); $notification = mysql_query($query_limit_notification, $connection_ched) or die(mysql_error()); $row_notification = mysql_fetch_assoc($notification); if (isset($_GET['totalRows_notification'])) { $totalRows_notification = $_GET['totalRows_notification']; } else { $all_notification = mysql_query($query_notification); $totalRows_notification = mysql_num_rows($all_notification); } $totalPages_notification = ceil($totalRows_notification/$maxRows_notification)-1;

  • Can typeid() be used to pass a function?

    - by Kerb_z
    I tried this and got the output as: void Please explain the following Code: #include <cstdio> #include <typeinfo> using namespace std ; void foo() { } int main(void) { printf("%s", typeid(foo()).name());// Please notice this line, is it same as typeid( ).name() ? return 0; } AFAIK: The typeid operator allows the type of an object to be determined at run time. So, does this sample code tell us that a function that returns void is of *type void*. I mean a function is a method and has no type. Correct?

    Hello! I have these 2 tables, Medication containing: IDMedication, IDCategory, Name, and Supplier, containing: IDSupplier, Name. I want to automatically create a relationship table, MedicationSupplier, containing: IDMedication and IDSupplier as keys, Price, and Quantity. My idea was to have a main page where i request the following data: (Medication)Name, IDCAtegory, (Supplier)Name, Price, Quantity. I'm not sure if i'm doing the right thing here. So this is what i'm receiveing in the .php where i do the insert: $Denumire=$_POST['Denumire']; //Medication Name $IDCategorie=$_POST['IDCategorie']; //IDCategory $Nume=$_POST['Nume']; //Supplier Name $Pret=$_POST['Pret']; //Price $Stoc=$_POST['Stoc']; //Quantity And this is my insert: $q_produse = "INSERT INTO produse VALUES ('','$IDCategorie','$Denumire')"; $q_prodfurniz = "INSERT INTO produsfurnizor VALUES ('','$IDFurnizor','$Pret','$Stoc')"; mysql_query($q_produse) or die($error); mysql_query($q_prodfurniz) or die($error); mysql_close(); My main problem at the moment is that i don't know how to insert IDMedication in the relationship table. Any help / suggestions of improving my code would be greatly appreciated. Thanks!

  • Reversing a hash function

    - by martani_net
    Hi, I have the following hash function, and I'm trying to get my way to reverse it, so that I can find the key from a hashed value. uint Hash(string s) { uint result = 0; for (int i = 0; i < s.Length; i++) { result = ((result << 5) + result) + s[i]; } return result; } The code is in C# but I assume it is clear. I am aware that for one hashed value, there can be more than one key, but my intent is not to find them all, just one that satisfies the hash function suffices. Any ideas? Thank you.
