  • A generic Re-usable C# Property Parser utility

    - by Shyam K Pananghat
    This is about a utility i have happened to write which can parse through the properties of a data contracts at runtime using reflection. The input required is a look like XPath string. since this is using reflection, you dont have to add the reference to any of your data contracts thus making pure generic and re- usable.. you can read about this and get the full c# sourcecode here. Property-Parser-A-C-utility-to-retrieve-values-from-any-Net-Data-contracts-at-runtime Now about the doubts which i have about this utility. i am using this utility enormously i many places of my code I am using Regex repetedly inside a recursion method. does this affect the memmory usage or GC collection badly ?do i have to dispose this manually. if yes how ?. The statements like obj.GetType().GetProperty() and obj.GetType().GetField() returns .net "object" which makes difficult or imposible to introduce generics here. Does this cause to have any overheads like boxing ? on an overall, please suggest to make this utility performance efficient and more light weight on memmory

  • I am trying to access the individual bytes in a floating point number and I am getting unexpected results

    - by oweinh
    So I have this so far: #include <iostream> #include <string> #include <typeinfo> using namespace std; int main () { float f = 3.45; // just an example fp# char* ptr = (char*)&f; // a character pointer to the first byte of the fp#? cout << int(ptr[0]) << endl; // these lines are just to see if I get what I cout << int(ptr[1]) << endl; // am looking for... I want ints that I can cout << int(ptr[2]) << endl; // otherwise manipulate. cout << int(ptr[3]) << endl; } the result is: -51 -52 92 64 so obviously -51 and -52 are not in the byte range that I would expect for a char... I have taken information from similar questions to arrive at this code and from all discussions, a conversion from char to int is straightforward. So why negative values? I am trying to look at a four-byte number, therefore I would expect 4 integers, each in the range 0-255. I am using Codeblocks 13.12 with gcc 4.8.1 with option -std=C++11 on a Windows 8.1 device.

  • Is it best to make fewer calls to the database and output the results in an array?

    - by Jonathan
    I'm trying to create a more succinct way to make hundreds of db calls. Instead of writing the whole query out every time I wanted to output a single field, I tried to port the code into a class that did all the query work. This is the class I have so far: class Listing { /* Connect to the database */ private $mysql; function __construct() { $this->mysql = new mysqli(DB_LOC, DB_USER, DB_PASS, DB) or die('Could not connect'); } function getListingInfo($l_id = "", $category = "", $subcategory = "", $username = "", $status = "active") { $condition = "`status` = '$status'"; if (!empty($l_id)) $condition .= "AND `L_ID` = '$l_id'"; if (!empty($category)) $condition .= "AND `category` = '$category'"; if (!empty($subcategory)) $condition .= "AND `subcategory` = '$subcategory'"; if (!empty($username)) $condition .= "AND `username` = '$username'"; $result = $this->mysql->query("SELECT * FROM listing WHERE $condition") or die('Error fetching values'); $info = $result->fetch_object() or die('Could not create object'); return $info; } } This makes it easy to access any info I want from a single row. $listing = new Listing; echo $listing->getListingInfo('','Books')->title; This outputs the title of the first listing in the category "Books". But if I want to output the price of that listing, I have to make another call to getListingInfo(). This makes another query on the db and again returns only the first row. This is much more succinct than writing the entire query each time, but I feel like I may be calling the db too often. Is there a better way to output the data from my class and still be succinct in accessing it (maybe outputting all the rows to an array and returning the array)? If yes, How?

  • [c++/STL] Selective iterator

    - by rubenvb
    FYI: no boost, yes it has this, I want to reinvent the wheel ;) Is there some form of a selective iterator (possible) in C++? What I want is to seperate strings like this: some:word{or other to a form like this: some : word { or other I can do that with two loops and find_first_of(":") and ("{") but this seems (very) inefficient to me. I thought that maybe there would be a way to create/define/write an iterator that would iterate over all these values with for_each. I fear this will have me writing a full-fledged custom way-too-complex iterator class for a std::string. So I thought maybe this would do: std::vector<size_t> list; size_t index = mystring.find(":"); while( index != std::string::npos ) { list.push_back(index); index = mystring.find(":", list.back()); } std::for_each(list.begin(), list.end(), addSpaces(mystring)); This looks messy to me, and I'm quite sure a more elegant way of doing this exists. But I can't think of it. Anyone have a bright idea? Thanks PS: I did not test the code posted, just a quick write-up of what I would try

  • Using jQuery .find() with multiple conditions at the same time?

    - by fuzzybabybunny
    I know that there are other ways of grabbing radio button values, but I want to know how to do this with .find(). I only want to log the value of the selected radio button, so it requires finding by two conditions at the same time: The button with name=area The button with selected=selected <div class="radio"> <label> <input class="track-order-change" type="radio" name="area" id="area1" value="area1" checked="checked"> Area 1 </label> </div> <div class="radio"> <label> <input class="track-order-change" type="radio" name="area" id="area2" value="area2"> Area 2 </label> </div> <div class="radio"> <label> <input class="track-order-change" type="radio" name="area" id="area3" value="area3"> Area 3 </label> </div> When anything with the class track-order-change changes, it will run the function UpdateOrderSubmission. $('.track-order-change').on('change', function() { updateOrderSubmission() }); I want the updateOrderSubmission function to console log the value of the radio button that is selected. var updateOrderSubmission = function() { var orderSubmission = { area: $('#submit-initial-form').find('[name=area],[checked=checked]').this.val() } console.log(orderSubmission) }; The code above doesn't work. How do I grab the value of the selected radio button? I need to do .find() with two conditions (name and checked), not just one condition.

  • Unit Conversion from feet to meters

    - by user1742419
    I have to write a program that reads in a length in feet and inches and outputs the equivalent length in meters and centimeters. I have to create three functions: one for input, one or more for calculating, and one for output; And include a loop that lets the user repeat this computation for new input values until the user says he or she wants to end the program. I can't seem to get the input from one function to be used in the conversion function and then outputted by the next function. How do I do that? Thank you. #include <iostream> #include <conio.h> using namespace std; double leng; void length(double leng); double conv(double leng); void output(double leng); int main() { length(leng); conv(leng); output(leng); _getche(); return 0; } void length(double leng) { cout<<"Enter a length in feet, then enter a length in inches if needed: "; cin>>leng; return; } double conv(double leng) { return leng = leng * .3048; } void output(double leng) { cout<<"Your input is converted to "<<leng; return; }

  • Javascript in php

  • How do I remove unnecessary options from a select field in a Drupal form?

    - by thismax
    I'm using the better_exposed_filters module to create a set of exposed filters for a view. One of the filters is being displayed as a select field, and I would like the field to only display options that are actually associated with content in the database. Currently, I am doing this using the hook_form_alter() method. For simplification, in the following example the field is called 'foo' and the content type with that field is called 'bar': function my_module_form_alter(&$form, $form_state, $form_id) { // Get all the values of foo that matter $resource = db_query('select distinct field_foo_value from {content_type_bar}'); $foo = array(); while($row = db_fetch_object($resource)) { $foo[$row->field_foo_value] = $row->field_foo_value; } $form['foo']['#options'] = $manufacturers; } This works great -- the form displays only the options I want to display. Unfortunately, the view doesn't actually display anything initially and I also get the following error message: An illegal choice has been detected. Please contact the site administrator. After I filter options with the form once, everything seems to work fine. Does anyone know how I can solve this problem? I'm open to an entirely different way of weeding out filter options, if need be, or a way that I can figure out how to address that error.

  • Is this the best way to grab Common element from a Hash of arrays?

    - by Hulihan Applications
    I'm trying to get a common element from a group of arrays in Ruby. Normally, you can use the & operator to compare two arrays, which returns elements that are present or common in both arrays. This is all good, except when you're trying to get common elements from more than two arrays. However, I want to get common elements from an unknown, dynamic number of arrays, which are stored in a hash. I had to resort to using the eval() method in ruby, which executes a string as actual code. Here's the function I wrote: def get_common_elements_for_hash_of_arrays(hash) # get an array of common elements contained in a hash of arrays, for every array in the hash. # ["1","2","3"] & ["2","4","5"] & ["2","5","6"] # => ["2"] # eval("[\"1\",\"2\",\"3\"] & [\"2\",\"4\",\"5\"] & [\"2\",\"5\",\"6\"]") # => ["2"] eval_string_array = Array.new # an array to store strings of Arrays, ie: "[\"2\",\"5\",\"6\"]", which we will join with & to get all common elements hash.each do |key, array| eval_string_array << array.inspect end eval_string = eval_string_array.join(" & ") # create eval string delimited with a & so we can get common values return eval(eval_string) end example_hash = {:item_0 => ["1","2","3"], :item_1 => ["2","4","5"], :item_2 => ["2","5","6"] } puts get_common_elements_for_hash_of_arrays(example_hash) # => 2 This works and is great, but I'm wondering...eval, really? Is this the best way to do it? Are there even any other ways to accomplish this(besides a recursive function, of course). If anyone has any suggestions, I'm all ears. Otherwise, Feel free to use this code if you need to grab a common item or element from a group or hash of arrays, this code can also easily be adapted to search an array of arrays.

  • How to detect if a RGB is fully transparent?

    - by omega
    In java, I want to make a fully transparent RGBA, and I do that by using public static int getTransparentRGB() { int r = 0; int g = 0; int b = 0; int a = 0; int new_pixel = (a << 24) | (r << 16) | (g << 8) | b; return new_pixel; } Color color = new Color(getTransparentRGB()); System.out.println(color.getAlpha()); // -> 255 ?! I purposely keep all rgba values 0. However after I create the Color object with the rgba value as the constructor, if I call .getAlpha(), I get 255 even though I made the rgb value with a 0 alpha. If it returns 255, how could I tell the difference between a Color object that wasn't transparent, because that would also have a 255 alpha. I expect the color object to return a 0 alpha based on the function above. Does anyone know whats going on? Thanks

  • Class Inside Structure

    - by Knvn
    Could some one please explain, What happens when a reference type is defined inside the value type. I write the following code: namespace ClassInsideStruct { class ClassInsideStruct { static void Main(string[] args) { ValueType ObjVal = new ValueType(10); ObjVal.Display(); ValueType.ReferenceType ObjValRef = new ValueType.ReferenceType(10); ObjValRef.Display(); Test(ObjVal, ObjValRef); ObjVal.Display(); ObjValRef.Display(); Console.ReadKey(); } private static void Test(ValueType v, ValueType.ReferenceType r) { v.SValue = 50; r.RValue = 50; } } struct ValueType { int StructNum; ReferenceType ObjRef; public ValueType(int i) { StructNum = i; ObjRef = new ReferenceType(i); } public int SValue { get { return StructNum; } set { StructNum = value; ObjRef.RValue = value; } } public void Display() { Console.WriteLine("ValueType: " + StructNum); Console.Write("ReferenceType Inside ValueType Instance: "); ObjRef.Display(); } public class ReferenceType { int ClassNum; public ReferenceType(int i) { ClassNum = i; } public void Display() { Console.WriteLine("Reference Type: " + ClassNum); } public int RValue { get { return ClassNum; } set { ClassNum = value; } } } } } Which outputs: ValueType: 10 ReferenceType Inside ValueType Instance: Reference Type: 10 Reference Type: 10 ValueType: 10 ReferenceType Inside ValueType Instance: Reference Type: 50 Reference Type: 50 I'm curious to know, after calling the method Test(ObjVal, ObjValRef), how the values of ReferenceType is changed to 50 which resides inside the ValueType who's value is not changed?

  • SQL Trigger Need to set x from a value

    - by Eric
    Im stuck on a the type of trigger needed to for this constraint. I will have a price and a commission. The price determines the commission amount, < 100 - 4%, < 200 - 5% etc. My idea. the database contains a separate table that will hold 4 price values , 101, 201, 401, 601, with their own matching comission %, this will be called PC. When i create a property listing i want to calculate the commission they earn depending on the price entered. on insert, i need to check the new.price and compare it to the prices in PC. Once new.price is less than the price tuple, i set the price to that commission value create or replace TRIGGER findCommission BEFORE INSERT OR UPDATE ON HASLISTING FOR each ROW BEGIN IF (:NEW.ASKING_PRICE < 100001) THEN :NEW.COMMISSION = 6.0; END IF; IF (:NEW.ASKING_PRICE < 250001) THEN :NEW.COMMISSION = 5.5; END IF; IF (:NEW.ASKING_PRICE < 1000001) THEN :NEW.COMMISSION = 5.0; END IF; IF (:NEW.ASKING_PRICE > 1000000) THEN :NEW.COMMISSION = 4.0; END IF; END;

  • Categorize data without consolidating?

    - by sqlnoob
    I have a table with about 1000 records and 2000 columns. What I want to do is categorize each row such that all records with equal column values for all columns except 'ID' are given a category ID. My final answer would look like: ID A B C ..... Category ID 1 1 0 3 1 2 2 1 3 2 3 1 0 3 1 4 2 1 3 2 5 4 5 6 3 6 4 5 6 3 where all columns (besides ID) are equal for IDs 1,3 so they get the same category ID and so on. I guess my thought was to just write a SQL query that does a group by on every single column besides 'ID' and assign a number to each group and then join back to my original table. My current input is a text file, and I have SAS, MS Access, and Excel to work with. (I could use proc sql from within SAS). Before I go this route and construct the whole query, I was just wondering if there was a better way to do this? It will take some work just to write the query, and I'm not even sure if it is practical to join on 2000 columns (never tried), so I thought I'd ask for ideas before I got too far down the wrong path. EDIT: I just realized my title doesn't really make sense. What I was originally thinking was "Is there a way I can group by and categorize at the same time without actually consolidating into groups?"

  • Returning a dynamically created array from function

    - by informer2000
    I'm trying to create a function that would dynamically allocate an array, sets the values of the elements, and returns the size of the array. The array variable is a pointer that is declared outside the function and passed as a parameter. Here is the code: #include <cstdlib> #include <iostream> using namespace std; int doArray(int *arr) { int sz = 10; arr = (int*) malloc(sizeof(int) * sz); for (int i=0; i<sz; i++) { arr[i] = i * 5; } return sz; } int main(int argc, char *argv[]) { int *arr = NULL; int size = doArray(arr); for (int i=0; i<size; i++) { cout << arr[i] << endl; } return 0; } For some reason, the program terminates on the first iteration of the for loop in main()! Am I doing something wrong?

  • Tigther code - javascript object array

    - by Scott Silvi
    Inside the callback of a $.getJSON call, I have the code outlined below. The first for block aggregates 'total' & assigns values to sov[i]. The map function calculates the percentage of total. I then instantiate a variable called sovData. With the jQuery Flot graph, any objects that are empty aren't added to the pie chart, so this works for up to 7 different slices/datasets. What I'd like to do is only initialize the ones I need (e.g. sovData would have up to 'howMany - 1' (kws.length -1 ) objects inside of it, likely via something similar to dashboards[i] & sov[i]. How would I do this? Code: var sov = [], howMany = kws.length, total = 0, i = 0; for ( i; i < howMany; i++) { total += sov[ i ] = +parseInt(data.sov['sov' + ( i+1 ) ],10) || 0; } var dashboards = data.dashboards; sov = $.map( sov, function(v) { var s = Math.round( ( (v / total) * 10e3 ) / 100); return s < 1 ? 1 : s; }); var sovData = [{ label : dashboards[0], data : sov[0] }, { label : dashboards[1], data : sov[1] }, { label : dashboards[2], data : sov[2] }, { label : dashboards[3], data : sov[3] }, { label : dashboards[4], data : sov[4] }, { label : dashboards[5], data : sov[5] }, { label : dashboards[6], data : sov[6] } ]

  • Need help finding a unique value in array

  • jQuery accessing objects

    - by user1275268
    I'm trying to access the values of an object from a function I created with a callback, but have run into some trouble. I'm still fairly new at jQuery/javascript. I call the function as follows: siteDeps(id,function(data){ $.each(data,function(key,val) { console.log(key); console.log(val); }); }); The function runs 5 ajax queries from XML data and returns data as an multidimensional object; here is a excerpt showing the meat of it: function siteDeps(id,callback) { var result = { sitecontactid : {}, siteaddressid : {}, sitephoneid : {}, contactaddressid : {}, contactphoneid : {} }; ...//.... var url5 = decodeURIComponent("sql2xml.php?query=xxxxxxxxxxx"); $.get(url5, function(data){ $(data).find('ID').each(function(i){ result.delsitephoneid[i] = $(this).text(); }); }); callback(result); } The console.log output shows this: sitecontactid Object 0: "2" 1: "3" __proto__: Object siteaddressid Object 0: "1" __proto__: Object sitephoneid Object 0: "1" 1: "5" 2: "54" __proto__: Object contactaddressid Object 0: "80" __proto__: Object contactphoneid Object 0: "6" __proto__: Object How can I extract the callback data in a format I can use, for instance sitephoneid: "1","5","54" Or is there a better/simpler way to do this?

    So I have this code to pass items from database to my order table. When I'm echoing the session. The session variable contains something so there's no problem with that. But when I echo those variables under numrows, it only shows nothing. Is there something wrong? <?php error_reporting(E_ALL ^ E_NOTICE); session_start(); require("connect.php"); $UserID = $_SESSION['CustNum']; $UserN = $_SESSION['UserName']; $ProdGTotal = $_SESSION['ProdGTotal']; $queryord = mysql_query("SELECT * FROM customer WHERE UserName = '$UserN'"); $numrows = mysql_num_rows($queryord); if(numrows == 1){ $row = mysql_fetch_assoc($queryord)or die ('Unable to run query:'.mysql_error()); // fetch associated: get function from a query for a database $dbstreet = $row['Street']; $dhousenum = $row['HouseNum']; $dbcnum = $row['CelNum']; $dbarea = $row['Area']; $dbbuilding = $row['Building']; $dbcity = $row['City']; $dbpnum = $row['PhoneNum']; $dbfname = $row['FName']; $dblname = $row['LName']; } else die(mysql_error()); $query4=mysql_query("INSERT INTO orderdetails VALUES ('', '$UserID', Now(), '$dbhousenum', '$dbstreet', '$dbarea', '$dbbuilding', '$dbcity', '$dbfname', '$dblname', '$dbcnum', '$dbpnum', '$ProdGTotal')",$connect); if ($query4){ header("location:index.php"); } else die(mysql_error()); ?>

  • How do I size a second div to be 100% height underneath a fixed image?

    - by mk
    I'm using semi-transparent PNGs (due to the designer's overlapping of elements) and trying to achieve a layout that represents the design while still working well on the web. Thus I have simple HTML: <div id="right"> <div id="welcome"></div> <div id="welcomeRepeatingBottom"></div> </div> And I'm trying to use CSS as follows: #right { height: 100%; position: absolute; right: 0px; top: 0px; width: 430px; } #welcome { background-image: url("welcome.png"); height: 614px; width: 430px; position: absolute; top: 0px; left: 0px; } #welcomeRepeatingBottom { background: url("welcomeBottom.png") repeat-y; height: 100%; left: 0px; position: absolute; top: 614px; width: 430px; } The problem is...the #welcomeRepeatingBottom div can't overlap the #welcome div because of the transparency. What I really want is the #welcomeRepeatingBottom div to be height: 100% - 614px, but of course you can't do that. Am I missing something here or do I need to manipulate these values with JavaScript/JQuery?
