  • How do i get (is it possible to) a reference to the class that creates an instance of another class.

    - by Cadde
    Odd situation... I need to create a new instance of a class that needs a member of the calling class. But i can't pass a reference to the calling class through the constructor. The solution i am looking for is something like this: Public Class ChildClass Public Sub New(args) _MyMember = GetMemberFromCallingClass() ... ... End Sub End Class I want this to work without having to manually pass any references or variables from the calling class to the new instance of ChildClass. Is this possible and if so, what should i look at to make this part of my code.

    My code is below: var statement = "test_oracle.sql"; F = aqFile.OpenTextFile(statement, aqFile.faRead, aqFile.ctANSI); F.Cursor = 0; while(! F.IsEndOfFile()){ s = F.ReadLine(); oResult = Project.Variables.oConnection.Execute_(s); CheckResult(oResult, "Unable to run SQL script to add documents"); The first line that "s" reads is: set serverout on size 10000 An error is returned as "ORA-00922: missing or invalid option" Can anyone provide guidance?

  • PHP __call vs method_exists

    - by neo
    The Project I'm working on contains something like a wrapper for call_user_func(_array) which does some checks before execution. One of those checks is method_exists (In Case the supplied first argument is an instance of a class and the second is a method name) The other is_callable. The function will throw an exception if one of those checks fails. My Code contains an array with function names (setFoo, setBar, etc.) and the php magic function for overloading (__call) which handles setting, replacing and deletion of certain variables (better certain array elements). The Problem: method_exists will return false if the function is not defined. Do I have any chance to get a true if the __call function does proper handling of the request?

  • ID cannot be null (Auto Increment)

    - by THeK
    I'm using an INSERT ON DUPLICATE KEY statement for my website. It's for creating news items, so I figured I could use the same MySQL command for both creating and updating news items. However, when I use the following: INSERT INTO table (id,title,content) VALUES(NULL,"Test","Test"); Instead of creating a new auto increment value it throws an error. However, the command works on my main development server. But not on my laptop. Both versions of MySQL are the same, the only difference being MySQL was installed manually on my server, and with WAMP on my laptop. Are there any MySQL Variables that could be causing this?

  • C++ string how to

    - by typoknig
    This is a very simple question and I feel stupid for asking it, but I am pressed for time and I need to figure it out :) I just need to know how to make a string that contains text and other variables. For instance in Java I can just do this: String someString; for(int i = 0; i>10; i++){ someString = ("this text has printed " + i + " times"); //how do I create this line in C++? System.out.println(someString); i++; }

  • [C++] Start a thread using a method pointer

    - by Michael
    Hi ! I'm trying to develop a thread abstraction (POSIX thread and thread from the Windows API), and I would very much like it to be able to start them with a method pointer, and not a function pointer. What I would like to do is an abstraction of thread being a class with a pure virtual method "runThread", which would be implanted in the future threaded class. I don't know yet about the Windows thread, but to start a POSIX thread, you need a function pointer, and not a method pointer. And I can't manage to find a way to associate a method with an instance so it could work as a function. I probably just can't find the keywords (and I've been searching a lot), I think it's pretty much what Boost::Bind() does, so it must exist. Can you help me ?

  • How do you pass objects between View Controllers in Objective-C?

    - by editor
    I've been trudging through some code for two days trying to figure out why I couldn't fetch a global NSMutableArray variable I declared in the .h and implemented in .m and set in a the viewDidLoad function. It finally dawned on me: there's no such thing as a global variable in Objective-C, at least not in the PHP sense I've come to know. I didn't ever really read the XCode error warnings, but there it was, even if not quite plain English: "Instance variable 'blah' accessed in class method." My question: What am I supposed to do now? I've got two View Controllers that need to access a central NSMutableDictionary I generate from a JSON file via URL. It's basically an extended menu for all my Table View drill downs, and I'd like to have couple other "global" (non-static) variables. Do I have to grab the JSON each time I want to generate this NSMutableDictionary or is there some way to set it once and access it from various classes via #import? Do I have to write data to a file, or is there another way people usually do this?

  • session expires to soon in php

    - by user1669425
    I want to extend a session time so that a session variable does not expire until after 12 hours. Problem is that after 24 minutes (default time for a session until it expires) of inactivity it still expires the session and hence gives me undefined indexes for those SESSION variables. What else do I need to do in the code below in order to be able to extend the sessions so that it does not expire on its own until 12 hours has passed: <?php ini_set('session.gc_maxlifetime',12*60*60); ini_set('session.cookie_lifetime',12*60*60); phpinfo(); session_start(); ....//rest of code below ?> in phpinfo() it states this below for gc_maxlifetime: Local Value Master Value session.gc_maxlifetime 43200 1440 session.cookie_lifetime 43200 0

  • How to hide URL from users when submitting this form?

    - by Camran
    I have a form with many many fields... When submitting these fields, I use the POST method which hides the actual variables passed along to the PHP page. However, I can't get rid of the complete link. Changing from GET to POST did make all the form fields invisible in the URL, but this part is still visible: mydomain.com/bin/query# I want it to be invisible, or say: mydomain.com/search I have mod_rewrite enabled so there is a possibility to do this with mod_rewrite I think, but I am new to mod_rewrite so I need your help... How should I hide this URL? If you need more input let me know...

  • jQuery Animation and Classes

    - by ehdv
    Assume you have a list item, <li id="foo"> which you want to fade from one color to another when moused over, and that you are using jQuery. This is fairly easy: $('li#foo').bind('mouseenter' , function(e) { $(this).animate({backgroundColor: '#F00'} , 300); }); However, what if you wanted to get the resulting color or other style rules from a class defined in CSS without also declaring them in JavaScript? It seems there's no way to learn style information from CSS rules without having an example of the rule already in the document, which would require you to animate the <li> to the target appearance, then in the animation-finished callback, set the class which leads to redundant style declarations and can foul up your CSS at "runtime". Sorry if this question's unclear: It doesn't occur in the context of any specific project, I'm just curious how you'd go about this. Also, I know CSS3 hypothetically includes support for such transitions but using CSS for dynamic behavior like this seems such an ugly hack.

  • Javascript: adding methods using prototype descriptor

    - by LDK
    Sorter.prototype.init_bubblesort = function(){ console.log(this.rect_array); this.end = this.rect_array.length; this.bubblesort(); } Sorter.prototype.init = function(array,sort_type){ this.rect_array = array; this.init_bubblesort(); } The code above works as expected, but when I change the init function to: Sorter.prototype.init = function(array,sort_type){ var sort_types = {'bubblesort':this.init_bubblesort, 'quicksort':this.init_quicksort, 'liamsort':this.init_liamsort}; this.rect_array = array; sort_types[sort_type](); } the init_bubblesort function results in an error saying this.rect_array is undefined. I'm trying to wrap my head around why init_bubblesort no longer as access to it's instance's variables.

    - 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', ),

  • Best place to create windows form objects

    - by user333484
    I'm creating a windows app in c# 2008 that will have around 8-10 dialog boxes. I want these forms to exist throughout the life of the program. Where's the best place to create and store the objects? I'm coming from Delphi, where Form objects were usually stored in global variables. I'm tempted to do it in the static Program class. Should I put them in the main form instead? Thanks for helping a C# newb out.

  • How to query one table and add rows to another using that first query? MySQL

    - by Nickelbids
    Hello, I have some users setup in a MySQL table with different variables. I am trying to figure out what would be the best way to do this. Basically I want to award all of my registered and active users with bids which are stored in another table. So for the Table "users" I have ran this query: SELECT * FROM users WHERE active = 1 AND admin = 0 ORDER BY users.id ASC Which will show all active users who are not administrators. Now I would like to give each one of these users which are identified by the "ID" field in another table. So in the "bids" table I would need to add a new row for each one of those users with all of the same values except for the "user_id" field which will basically match the "id" field of the table "users" What would be the best approach for this. There are approximately 6,000+ users coming up in the first query. Please be gentle as I am not a programmer. Just need some friendly advice.

  • How to check an exectuable's path is correct in PHP?

    - by nickf
    I'm writing a setup/installer script for my application, basically just a nice front end to the configuration file. One of the configuration variables is the executable path for mysql. After the user has typed it in (for example: /path/to/mysql-5.0/bin/mysql or just mysql if it is in their system PATH), I want to verify that it is correct. My initial reaction would be to try running it with "--version" to see what comes back. However, I quickly realised this would lead to me writing this line of code: shell_exec($somethingAUserHasEntered . " --version"); ...which is obviously a Very Bad Thing. Now, this is a setup script which is designed for trusted users only, and ones which probably already have relatively high level access to the system, but still I don't think the above solution is something I want to write. Is there a better way to verify the executable path? Perhaps one which doesn't expose a massive security hole?

  • VB to c++ or c#?

    - by hilzmas
    I am trying to translate this code but I don't understand how to use the GET / PUT part of the code in another language like c++ or c#. This is the code : Private Sub cmd_Click() Dim i As Integer, a As Integer a = 10 For i = 1 To a Dim file As String Open "txt" For Binary As #1 file = Space(LOF(1)) Get #1, , file Close #1 Randomize Open "txtpath" & "\" & i & "txtname" For Binary As #1 Put #1, , file Put #1, , Rnd Close #1 Next i End Sub The code could have bug because I replaced variables with plain text. What I understand is that the code get a file and then save it with some random data added to make it look different than the original. I don't use vb since years and I don't remember anything about it. Can someone help me porting this snippet to c++ or c#?

  • Dynamically choosing css property in animation

    - by paddywhack
    Hi, It seems a straightforward thing but I'm not having much success. I'm just implementing a simple animation moving a div left or up using animate() but I would like to be able to set the "top" and "left" css properties dynamically. I would like to use the same function rather than have to have two, one for "left" and one for "top". Here's some code which gives the idea. function test($element){ $element.click(function(){ var cssProperty; var direction = "left"; var moveTo = "100px"; if (direction === "top") { cssProperty = "top"; } else { cssProperty = "left"; } /*Using variable as CSS property - This doesn't work */ $(this).animate({ cssProperty: moveTo }, 1000); /*Using variable as the CSS Values - This does */ $(this).animate({ left: moveTo }, 1000); }); } Variables works on the css value side but not on the css selector side. Anyone have any suggestions? Thanks

(i don't want the Modelbinder to use New() and instantiate obj, but I want to deliver the object from a custom repository.) Is this possible? Edit: The loading from the repository should be done based on the id parameter of EditObject...

  • db2 stored procedure. locking / releasing table

    I use a stored procedure to read/update/return certain fields in a journaled as400 table. I want to lock the table first and then release it after the record is updated. I tried tons of stuff, but releasing table is a problem. SP defines and opens cursor, selects record into variables and updates the record. I tried 'begin atomic', then lock table in exclusive mode and then when it's over, it doesn't release. Is there any statement i missing or do i need to compile it with certain parameters? I use a simple create procedure statement in AS400 navigator's sql panel to compile it. Will very appreciate some help with example. Thanks.
