  • mysql_close(): supplied argument is not a valid MySQL-Link resource

    - by Illes Peter
    Here's what I'm trying to do: I've got a db.php file that does all the db manipulation. It has 2 static methods, connect and deconnect. In my other file i simply use db::connect() and db::deconnect(). The mysql_close($con) in the deconnect method just doesn't know who $con is. Since I don't want to instantiate my class static is the only way to go. Declaring 'private $con' in class db doesn't seem to have an effect. Any ideas? class db { public static function connect() { $dbData = parse_ini_file($_SERVER['DOCUMENT_ROOT'].'/config.ini'); $con = mysql_connect($dbData['host'],$dbData['user'],$dbData['pass']); $db = mysql_select_db($dbData['db']); if ((!$con) || (!$db)) return 0; else return 1; } public static function deconnect() { mysql_close($con); } }

  • NHibernate: how to do lookup a specific date

    - by Daoming Yang
    How I can lookup a specific date in Nhibernate? I'm currently using this to lookup one day's order. ICriteria criteria = SessionManager.CurrentSession.CreateCriteria(typeof(Order)) .Add(Expression.Between("DateCreated", date.Date.AddDays(-1), date.Date.AddDays(1))) .AddOrder(NHibernate.Criterion.Order.Desc("OrderID")); I tried the following code, but they did bring the data for me. Expression.Eq("DateCreated", date) Expression.Like("DateCreated", date) Note: The pass in date value will be like this 2010-04-03 00:00:00, The actual date value in the database will be like this 2010-03-13 11:17:16.000 Can anyone let me know how to do this? Many thanks.

  • Using C# to iterate form fields with same name

    - by itsatrp
    I have a section of a form that I need to handle differently from the rest of form results. In the section that needs special handling I need to iterate over 3 form fields that have the same name. They have to have the same name, I can't change it. The section of the form I am referring to looks something like this: <td><input name="Color" size="20" value="" type="text"></td> Using C# I try something like this: I try to handle it like this: int i; for (i = 1; i <= Request.Form["Color"][i]; i++) { colorName.Text += Request.Form["Color"]; } Which leads to the following exception: System.NullReferenceException: Object reference not set to an instance of an object. How should I be handling form fields with the same name?

  • Counting array in API JSON Response

    - by bryan
    I'm trying to do a simple count of how many refunds are in my Stripe Response but count() isn't working and I don't really know any other way of achieving this. Could anyone point me in the right direction? $retrieve_event = Stripe_Event::retrieve("evt_00000000000000"); $event_json_id = json_decode($retrieve_event); $refund_array = $event_json_id->{'data'}->{'object'}->{'refunds'}; die(count($refund_array)); This is the response of $retrieve_event { "created": 1326853478, "livemode": false, "id": "evt_00000000000000", "type": "charge.refunded", "object": "event", "request": null, "data": { "object": { "id": "ch_00000000000000", "object": "charge", "created": 1402433517, "livemode": false, "paid": true, "amount": 1000, "currency": "usd", "refunded": true, "card": { "id": "card_00000000000000", "object": "card", "last4": "0028", "type": "Visa", "exp_month": 8, "exp_year": 2015, "fingerprint": "a5KWlTcrmCYk5DIYa", "country": "US", "name": "First Last", "address_line1": "null", "address_line2": null, "address_city": "null", "address_state": "null", "address_zip": "null", "address_country": "US", "cvc_check": null, "address_line1_check": "fail", "address_zip_check": "pass", "customer": "cus_00000000000000" }, "captured": true, "refunds": [ { "id": "re_104CKt4uGeYuVLAahMwLA2TK", "amount": 100, "currency": "usd", "created": 1402433533, "object": "refund", "charge": "ch_104CKt4uGeYuVLAazSyPqqLV", "balance_transaction": "txn_104CKt4uGeYuVLAaSNZCR867", "metadata": {} }, { "id": "re_104CKt4uGeYuVLAaDIMHoIos", "amount": 200, "currency": "usd", "created": 1402433539, "object": "refund", "charge": "ch_104CKt4uGeYuVLAazSyPqqLV", "balance_transaction": "txn_104CKt4uGeYuVLAaqSwkNKPO", "metadata": {} }, { "id": "re_4CL6n1r91dY5ME", "amount": 700, "currency": "usd", "created": 1402434306, "object": "refund", "charge": "ch_4CL6FNWhGzVuAV", "balance_transaction": "txn_4CL6qa4vwlVaDJ" } ], "balance_transaction": "txn_00000000000000", "failure_message": null, "failure_code": null, "amount_refunded": 1000, "customer": "cus_00000000000000", "invoice": null, "description": "this is a description", "dispute": null, "metadata": {}, "statement_description": "this is a description", "fee": 0 } } }

  • C++ union assignment, is there a good way to do this?

    - by Sqeaky
    I am working on a project with a library and I must work with unions. Specifically I am working with SDL and the SDL_Event union. I need to make copies of the SDL_Events, and I could find no good information on overloading assignment operators with unions. Provided that I can overload the assignment operator, should I manually sift through the union members and copy the pertinent members or can I simply come some members (this seems dangerous to me), or maybe just use memcpy() (this seems simple and fast, but slightly dangerous)? If I can't overload operators what would my best options be from there? I guess I could make new copies and pass around a bunch of pointers, but in this situation I would prefer not to do that. Any ideas welcome!

  • Call load using a div id that has been passed into a function, div id is a parameter

    - by tittatty
    I am dynamically creating divs within a jquery accordion that are loaded with data as when the user clicks on the accordion title. I have this all working except that when I pass the div id into the load details method, the call to .load() does not work. What can I do to fix this? It seems like a simple javascript string eval would work but I can not find what I am looking for. Code: Here is the basic function: function loadDetails(div_id) { var load_string = "ajax/get_details.aspx"; $(div_id).load(load_string); } This function is called correctly on the click event and the div_id is passed in correctly but the load function is not working. If I use code like this it work correctly: $('#test').load(load_string);

  • Including associations optimization in Rails

    - by Vitaly
    Hey, I'm looking for help with Ruby optimization regarding loading of associations on demand. This is simplified example. I have 3 models: Post, Comment, User. References are: Post has many comments and Comment has reference to User (:author). Now when I go to the post page, I expect to see post body + all comments (and their respective authors names). This requires following 2 queries: select * from Post -- to get post data (1 row) select * from Comment inner join User -- to get comment + usernames (N rows) In the code I have: Post.find(params[:id], :include => { :comments => [:author] } But it doesn't work as expected: as I see in the back end, there're still N+1 hits (some of them are cached though). How can I optimize that?

  • Write a dll that is accessable from VS 2003 VC++ code

    - by John
    I need to be able to write a DLL in either C# or VC++ that is accessible from code that is written in Visual Studio 2003 VC++. It looks like the code is unmanaged (uses * for pointers) VC++ and this DLL needs to be able to drop right in and be accessed by the current code. The DLL is an RS232 driver that needs to be able to return an int for an error code and pass back, by reference, some measured values, to the calling program. Will I even be able to write this in C#? If not, I only have access to Visual Studio 2005 or 2008. Will I be able to write my code in either, and will that DLL be able to be called from the current code base? Or do I have to go looking on ebay for a copy of VS 2003?

  • Managing Data Prefetching and Dependencies with .NET Typed Datasets

    - by Derek Morrison
    I'm using .NET typed datasets on a project, and I often get into situations where I prefetch data from several tables into a dataset and then pass that dataset to several methods for processing. It seems cleaner to let each method decide exactly which data it needs and then load the data itself. However, several of the methods work with the same data, and I want the performance benefit of loading data in the beginning only once. My problem is that I don't know of a good way or pattern to use for managing dependencies (I want to be sure I load all the data that I'm going to need for each class/method that will use the dataset). Currently, I just end up looking through the code for the various classes that will use the dataset to make sure I'm loading everything appropriately. What are good approaches or patterns to use in this situation? Am I doing something fundamentally wrong? Although I'm using typed datasets, this seems like it would be a common situation where prefetching data is used. Thanks!

  • Ruby gems in lib - spare tire principle

    - by fregas
    Hi, I'm working on a console ruby application (not rails!) I will be installing this application on several machines. I was wondering if there is a way i can build it so i dont have to install the games i'm using for the app on each machine. I'd like to be able to just copy the directory to each machine and run it. Ideally, i'd like to put the gems in the lib folder or something and reference them from there, so i don't have to even install them on my dev machine. Is there a way to do this? In .net, we call this the "spare tire" principle. thanks, Craig

  • PHP Convert variable names to lowercase?

    - by VeeBee
    I have an api listener script which takes in get parameters. But I seem to be having issues when users tend to pass mixed case variable names on the parameters. For example: http://mylistenerurl.com?paramName1=Hello&paramname2=World I need my listener to be flixible in such a way that the variable names will be interpreted case-insensitively or rather still all in lower case like after I process the query string on some function, they are all returned as lower-cased variables: extract(someFunction($_GET)); process($paramname1, $paramname2); Can anybody shed some light on this? *much appreciated. thanks!

  • Constructor type not found

    - by WaffleTop
    Hello, What I am doing: I am taking the Microsoft Enterprise Library 4.1 and attempting to expand upon it using a few derived classes. I have created a MyLogEntry, MyFormatter, and MyTraceListener which derive from their respective base classes when you remove the "My" from their names. What my problem is: Everything compiles fine. When I go to run a test using Logger.Write(logEntry) it errors right after it initializes MyTraceListener with an error message: "The current build operation (... EnterpriseLibrary.Logging.LogWriter, null]) failed: Constructor on type 'MyLogging.MyFormatter' not found. (Strategy type ConfiguredObjectStrategy, index 2) I figured it was something to do with the constructor so I tried removing it, add it, and adding a call to the base class LogFormatter. Nothing has worked. Does anyone have insight into this problem? Is it maybe a reference issue? Bad App.config configuration? Thank you in advance

  • [JS/jQuery] Using argument (this) passed via element eventhandler

    - by Kel
    Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

  • Is it possible to position an element relative to the border-box of its parent?

    - by Timwi
    Consider the following jsfiddle for reference: http://jsfiddle.net/apmmw2ma/ As you can see, the “inner” box (with the red border) is positioned relative to the outer’s padding-box: left:0 positions it just to the right of outer’s border, and top:100% appears to mean “100% of the content plus padding, but not the border”. Unfortunately, adding box-sizing: border-box to the outer div seems to have no effect. I want to position a child element directly below its parent’s border-box, i.e. the two borders should abut no matter how thick they are. Is this possible?

  • Assign bitset member to char

    - by RedX
    I have some code here that uses bitsets to store many 1 bit values into a char. Basically struct BITS_8 { char _1:1; (...) char _8:1; } Now i was trying to pass one of these bits as a parameter into a function void func(char bit){ if(bit){ // do something }else{ // do something else } // and the call was struct BITS_8 bits; // all bits were set to 0 before bits._7 = 1; bits._8 = 1; func(bits._8); The solution was to single the bit out when calling the function: func(bits._8 & 0x128); But i kept going into //do something because other bits were set. I was wondering if this is the correct behaviour or if my compiler is broken. The compiler is an embedded compiler that produces code for freescale ASICs.

  • Question regarding two dimensional array

    - by Sherwood Hu
    I have some problems using two dimensional array in the code and need some help. static const int PATTERNS[20][4]; static void init_PATTERN() { // problem #1 int (&patterns)[20][4] = const_cast<int[20][4]>(PATTERNS); ... } extern void UsePattern(int a, const int** patterns, int patterns_size); // problem #2 UsePattern(10, PATTERNS, sizeof(PATTERNS)/sizeof(PATTERNS[0])); in the first statement, I need to cast the const off the two dimensional array PATTERNS. The reason for this is that the init function is called only once, and in the remaining code, PATTERNS is strictly read-only. In the second statement, I need to pass PATTERNS array to the int** argument. Direct passing resulted a compile error. Thanks!

  • Whats the python way for recursively setting file permissions?

    - by Geoff
    What's the "python way" to recursively set the owner and group to files in a directory? I could just pass a 'chown -R' command to shell, but I feel like I'm missing something obvious. I'm mucking about with this: import os path = "/tmp/foo" for root, dirs, files in os.walk(path): for momo in dirs: os.chown(momo, 502, 20) This seems to work for setting the directory, but fails when applied to files. I suspect the files are not getting the whole path, so chown fails since it can't find the files. The error is: 'OSError: [Errno 2] No such file or directory: 'foo.html' What am I overlooking here?

  • Whats are basic things you should kept in mind while writing functional tests?

    - by piemesons
    Hello, what kind of functionality should be covered in functional test? How to prioritize what are the functionality that must be covered in functional test. I can understand it depends upon on the project, whats the functionality present the project. Lets take a example of stackoverflow. Suppose we are developing a basic working model of this. What kind of functional test must be covered in this. Just brief what the key points while writing functional tests. (taking any basic functionality from this site just to understand the reference) Still its platform independent question.I am using ruby on rails developer, but keeping ruby on rails as mind will be preferable.

  • Is it possible to programmatically control c# health monitoring without using the web.config file?

    - by Adam
    I have developed my own custom provider for the health monitoring; however, I use parameters in the constructor and this is not allowed when using the health monitoring from the web.config file. Does anyone know if I can turn on/off the monitoring and have it watch properly through code (possibly in my global.asax file on application startup). Or, is it possible for me to create my own watcher that will do the same thing as the health monitor. Or, finally - can I just pass variables from the web.config setup (i'm not familiar with the public token part of the provider type declaration). Thanks in advance

  • Reflection & Parameters in C#

    - by Jim
    Hello, I'm writing an application that runs "things" to a schedule. Idea being that the database contains assembly, method information and also the parameter values. The timer will come along, reflect the method to be run, add the parameters and then execute the method. Everything is fine except for the parameters. So, lets say the method accepts an ENUM of CustomerType where CustomerType has two values of CustomerType.Master and CustomerType.Associate. EDIT I don't the type of parameter that will be getting passed in. ENUM used as an example END OF EDIT We want to run Method "X" and pass in parameter "CustomerType.Master". In the database, there will be a varchar entry of "CustomerType.Master". How do I convert the string "CustomerType.Master" into a type of CustomerType with a value of "Master" generically? Thanks in advance, Jim

  • C# - Copy dlls to the exe output directory when using dependency injection with no references?

    - by NotDan
    I have a C# solution that I am using dependency injection to resolve references between dlls. I have an exe project and some other dll projects that are not referenced by the exe (It uses the dlls through the IoC container). The project settings are the default, visual studio settings where it builds each dll in it's own folder. Since the exe doesn't reference the dlls, they never get copied to the output directory of the exe and don't get found by the IoC framework. How do you handle this? Do you build them all in the same directory? Use post build copy commands? Or something else?
