• Multiple Controls on a Page with Multiple Instances of Javascript

  - by mattdell

  I have created a Web Control in ASP for use in integrating with Telligent CommunityServer. The control is written in ASP with some 10 lines of C# backend for controlling visibility of the UI elements based on permissions, but I'd say 90% of the functionality is straight-up Javascript. The control works beautifully, until you drop two instances of the Control on the same page--since they reference the exact same Javascript functions, only one control works. How can I take this functionality that I have, this 1200 lines of Javascript, and make it so that each instance of the control can reference its each unique instance of Javascript?

• How do I pass custom variables to javascript events?

  - by RoboShop

  I have a user control with a javascript function which references some controls within the user control. This user control works perfectly when there is only one instance of it, but I'm now building a page where I have two instances of the user control. In IE7, it works fine, but in FireFox, it is getting confused that there is two functions of the exact same name and signature. So on UserControl1, it'll be running the function in UserControl2 and modifying that content. I'm thinking my best solution would be to pass the clientID of the components I need TO the function instead of just directly referencing it in the function. How would I do that? The signature of the javascript function is like this function nodeClicking(sender, args) and I'm calling it in an event like this <telerik:RadTreeView runat="server" ID="OrgUnitTreeView" OnInit="TreeViewLoad" OnClientNodeClicking="**nodeClicking**" EnableViewState="true" DataTextField = "OrganisationUnitName" DataValueField = "OrganisationUnitCode" DataFieldParentID = "ParentOrganisationUnitCode" DataFieldID = "OrganisationUnitCode"> How do I add extra variables to the function signature.

• SEARCHING AND REPLACING BRACKETS IN A STRING IN ORACLE 10G

  - by Tunde

  hello, Thanks as usual for your prompt and kind suggestions. i am currently developing a function that is meant to execute dynamically created SQL statements. this is done by concatenating the columns and fetching them via cursors. the problem is that when there is a function with a comma between its arguments, the concat concatenates the contents of the functions inclusive. Is it possible to skip contents of every bracket found in a string using REGEXP_SUBTR or REGEXP_REPLACE? Many thanks for the anticipated response.

• UIView Animation won't run transition

  - by dpelletier

  So, I've searched quite a bit for this and can't seem to find a solution. This code works: CGContextRef context = UIGraphicsGetCurrentContext(); [UIView beginAnimations:nil context:context]; [UIView setAnimationDuration:5]; [c setCenter:CGPointMake(200, 200)]; [UIView commitAnimations]; This code doesn't: CGContextRef context = UIGraphicsGetCurrentContext(); [UIView beginAnimations:nil context:context]; [UIView setAnimationBeginsFromCurrentState:YES]; [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:c cache:YES]; [UIView setAnimationDuration:5]; [c exchangeSubviewAtIndex:0 withSubviewAtIndex:1]; [UIView commitAnimations]; And I know the call to exchangeSubViewAtIndex is working because if I remove it from the animation block it functions as expected. Anyone have any insight as to why this transition won't run? Something I need to import?

• How i draw the graph including X- and Y-axis lines?

  - by Rajendra Bhole

  Hi, I want to make an application in which i want to make simple graph using NSObject class and using CGContext method. All lines should be displaying dynamically in X and Y-axis interval text also, i trying develop something like following code, CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextSetLineWidth(ctx, 2.0); //(number of lines) CGContextMoveToPoint(ctx, 30.0, 230.0); CGContextAddLineToPoint(ctx, 30.0, 440.0); //CGContextAddLineToPoint(ctx, 320.0, 420.0); //CGContextStrokePath(ctx); for(float x = 20.0; x <= 320.0; x++) { CGContextSetRGBStrokeColor(ctx, 2.0, 2.0, 2.0, 1.0); CGContextMoveToPoint(ctx, x, 420.0); CGContextAddLineToPoint(ctx, x+45.0, 420.0); CGContextStrokePath(ctx); } How i develop using above functions? Thanks.

• Using free function as pseudo-constructors to exploit template parameter deduction

  - by Poita_

  Is it a common pattern/idiom to use free functions as pseudo-constructors to avoid having to explicitly specify template parameters? For example, everyone knows about std::make_pair, which uses its parameters to deduce the pair types: template <class A, class B> std::pair<A, B> make_pair(A a, B b) { return std::pair<A, B>(a, b); } // This allows you to call make_pair(1, 2), // instead of having to type pair<int, int>(1, 2) // as you can't get type deduction from the constructor. I find myself using this quite often, so I was just wondering if many other people use it, and if there is a name for this pattern?

• How to use Zend Cache with SimpleXML objects?

  - by Jeremy Hicks

  I'm trying to cache the user timeline of a Twitter feed using Zend_Service_Twitter which returns its results as a SimpleXML object. Unfortunately the regular serialize functions (which Zend Cache uses) don't play nice with SimpleXMl objects. I found this http://www.mail-archive.com/[email protected]/msg18133.html. So it looks like I'll need to create some kind of custom frontend for Zend Cache to be able to change the serialize function used. Anybody ever done this already or can point me where to look to start?

• Declare two classes from eachother.

  - by tumba25

  I'm writing a app in NetBeans. I have two classes MyApp_View and MyApp_Functions. The MyApp_View class starts like this public class MyApp_View extends FrameView { MyApp_Functions My_functions = new MyApp_Functions(); public MyApp_View(SingleFrameApplication app) { super(app); In MyApp_Functions I have MyApp_View my_view = new MyApp_View(null); I want to access the public variables in MyApp_View from MyApp_Functions and the public methods in functions from view, but have no success with this. Is this doable? And how?

• Data Access Layer in an ASP.NET website

  - by user3519124

  :) i have a DAL class file in my project, that my teacher sent me and explained to me but i did not really understand it. It has number of functions, and I understand only few of them, like with connecting to the database or creating a command object but there are 2 that I dont understand: public static DataTable GetTable(string str) { OleDbConnection con = DAL.GetConnection(); OleDbCommand cmd = DAL.GetCommand(con, str); DataTable dt = new DataTable(); OleDbDataAdapter adp = new OleDbDataAdapter(); adp.SelectCommand = cmd; adp.Fill(dt); return dt; } public static int ExecuteNonQuery(string str) { int num = -1; OleDbConnection con = DAL.GetConnection(); con.Open(); if (con.State == ConnectionState.Open) { OleDbCommand cmd = DAL.GetCommand(con, str); num = cmd.ExecuteNonQuery(); con.Close(); } return num; } thank you :)

• How can I fix the scroll bug when using Windows rich edit controls in wxpython?

  - by ChrisD

  When using wx.TextCtl with the wx.TE_RICH2 option in windows, I get this strange bug with the auto-scroll when using the AppendText function. It scrolls so that all the text is above the visible area, which isn't very useful behaviour. I tried just adding a call to ScrollLines(-1) after appending the text - which does scroll it to the correct position - but this can lead to the window flashing when it auto-scrolls. So I'm looking for another way to automatically scroll to the bottom. So far, my solution is to bypass the AppendText functions auto-scroll and implement my own, like this: def append_text(textctrl, text): before_number_of_lines = textctrl.GetNumberOfLines() textctrl.SetInsertionPointEnd() textctrl.WriteText(text) after_number_of_lines = textctrl.GetNumberOfLines() textctrl.ScrollLines(before_number_of_lines - after_number_of_lines + 1) Is there a better way?

• Converting a jQuery plugin to work on all objects, not just the DOM

  - by Jon Winstanley

  I am using the jQuery physics plugin for a pet project I am working on. The plugin enables the moving of DOM objects in realistic ways using velocity, gravity, wind etc. However I want to use the plugin to calculate where objects are to be placed inside a canvas element, not DOM object. How do I change the plugin script to work for ANY object with 'top' and 'left' properties rather than only working with DOM objects found with a jQuery selector? Currently the script functions look like this: jQuery.fn.funname = function() { return this; };

• Show javascript execution progress

  - by Midhat

  I have some javascript functions that take about 1 to 3 seconds. (some loops or mooML templating code.) During this time, the browser is just frozen. I tried showing a "loading" animation (gif image) before starting the operation and hiding it afterwords. but it just doesnt work. The browser freezes before it could render the image and hides it immediately when the function ends. Is there anything I can do to tell the browser to update the screen before going into javascript execution., Something like Application.DoEvents or background worker threads. So any comments/suggestions about how to show javascript execution progress. My primary target browser is IE6, but should also work on all latest browsers

• cross-domain data with AJAX using JSONP

  - by kooshka

  I'm trying to get data from Geobytes. One of the templates returns JSON and I need to cross-domain access it. I wrote these 2 functions function getCountry(ip) { var surl = "http://www.geobytes.com/IpLocator.htm?GetLocation&template=json.txt"; $.ajax({ url: surl, data: '{"ipaddress":"' + ip + '"}', dataType: "jsonp", jsonp: "callback", jsonpCallback: "jsonpcallback" }); } function jsonpcallback(rtndata) { alert(rtndata.message); } The call is executed but I get 1 warning: Resource interpreted as Script but transferred with MIME type text/html: "http://www.geobytes.com/IpLocator.htm?GetLocation&template=json.txt&callback=jsonpcallback&{%22ipaddress%22:%22200.167.254.166%22}&_=1353148931121" 1 Error: Uncaught SyntaxError: Unexpected token : The error is thrown on the returned data at {"geobytes":{"countryid":117, I think is maybe because it's 117 and not "117" but I obviously can't control the returned data How can I fix these 2 issues?

• need identical string comparison function in php and java

  - by steelbytes

  I have sorted list of strings that I move between php and java. to be able to bsearch on this data, I need the same comparison function. any idea what string compare functions I can use that will always give the same result in both? eg php's strcmp() vs java's String.compareTo() yes I know I could make my own string compare that does char by char carefully, but I was hoping there's a simple answer. PS, don't care if case sensitive or not, as long as it is consistant.

• SQLAlchemy custom sorting algorithms when using SQL indexes

  - by David M

  Is it possible to write custom collation functions with indexes in SQLAlchemy? SQLite for example allows specifying the sorting function at a C level as sqlite3_create_collation(). An implementation of some of the Unicode collation algorithm has been provided by James Tauber here, which for example sorts all the "a"'s close together whether they have accents on them or not. Other examples of why this might be useful is for different alphabet orders (languages other than English) and sorting numeric values (sorting 10 after 9 rather than codepoint order.) Is this possible in SQLAlchemy? If not, is it supported by the pysqlite3 or MySQLdb modules, or for any other SQL database modules supported by python for that matter? Any information would be greatly appreciated.

• 3D effect to distort paper

  - by donpal

  This may be a little hard to describe since I don't have a sample. I'm trying to find a math function or full 3d function in php or a similar language that can help me with the following effect: imagine if you were to take a flat sheet or paper and glue it on a glass of water. It wouldn't be flat any more. It would have a curve, and one of its sides might end up being slightly hidden. Anyone can refer me to a good library or resource on the web where such functions can be found?

• Naming Optional Parameters in VSB

  - by SteveNeedsSheetNames

  In Visual Basic, I have Functions with a lot of Optional arguments. I would like to be able to pass just a few of these Optional arguments to a Function without having to use numerous commas and spaces to get to the ones I want. Somewhere I saw a way to name params such as OptVar:=val, but that does not seem to work. Just wondering if there is a way to do this. This would help readability. Thanks in advance for the replies.

• UTF-8 xml file shows Gibberish

  - by Adam

  I have a UTF-8 encoded xml file, which was exported from a Wordpress MySQL database. While the file is saved as UTF-8, and the encoding is UTF-8, I get gibberish instead of the Hebrew text that is supposed to be in there, which looks like this: ™×•×˜×•×ª How can I find the original encoding or charset and convert the text into proper Hebrew? PHP's mb_detect_encoding($str); returns UTF-8 Tried all sorts of php encoding functions, with different settings and input/output charsets, but they all just print different looking gibberish blocks, like: ÃâÃËÃâ¢Ãâ¢ÃËà and ?? ××©×ž× ...Any Ideas how to go about this?

• Query Only Specified Number Of Items From Parent/Child Categories

  - by RogeR

  I'm having trouble figureing out how to query every item in a certain category and only list the newest 10 items by date. Here is my table layout: download_categories category_id (int) primary key title (var_char) parent_id (int) downloads id (int) primary key title (var_char) category_id (int) date (date) I need to query every file in a main category that lets say has 100 items and 5 child categories and only spit out the last 10 added. I have functions right now that just add up all the files so I can get a count by category, but I can't seem to modify the code to only display a certain amount of items based on the date.

• Microsoft _stprintf warning

  - by mnh

  Why I get the following warning for the following code :) Code: _stprintf(m_szFileNamePath,_T("%s"),strFileName); warning C4996: '_swprintf': swprintf has been changed to conform with the ISO C standard, adding an extra character count parameter. To use traditional Microsoft swprintf, set _CRT_NON_CONFORMING_SWPRINTFS. I know _strprintf is a macro which if _UNICODE is defined will evaluate to _swprintf else it will be sprintf. Now what is this _swprintf. There is a function swprintf, but why is _stprintf evaluating to _swprintf instead of swprintf. What is the difference b/w the _xxx and xxx functions? EDIT: Okay there are two definitions for the UNICODE version of _stprintf, which one is included? The one in tchar.h or strsafe.h?

• Error in R for missing object

  - by griffin

  I have several nested functions, some of which as called in lapply clauses. In the process, sometimes I don't set a default for a parameter and instead check if it was supplied using the missing function. I'm getting a strange error right now when I'm not passing a value for a parameter, it has no default, yet missing resolves to FALSE. And when I try to use or check the parameter in any other way (using length, exists, etc.), I get an error: Error in try(length(x)) : argument "data" is missing, with no default Has anyone experienced this failure of the missing function before?

The issue comes in when I try to call a few php functions on the image... such as getimagesize or fopen... they both return 404 errors even though the image is there. Does anyone know that could be causing this? Thank you for your time.

• Why must "stride" in the System.Drawing.Bitmap constructor be a multiple of 4?

  - by Gorchestopher H

  I am writing an application that requires me to take a proprietary bitmap format (an MVTec Halcon HImage) and convert it into a System.Drawing.Bitmap in C#. The only proprietary functions given to me to help me do this involve me writing to file, except for the use of a "get pointer" function. This function is great, it gives me a pointer to the pixel data, the width, the height, and the type of the image. My issue is that when I create my System.Drawing.Bitmap using the constructor: new System.Drawing.Bitmap(width, height, stride, format, scan) I need to specify a "stride" that is a multiple of 4. This may be a problem as I am unsure what size bitmap my function will be hit with. Supposing I end up with a bitmap that is 111x111 pixels, I have no way to run this function other than adding a bogus column to my image or subtracting 3 columns. Is there a way I can sneak around this limitation?

• Unable to access global variable defined in settings.php [Drupal]

'/another/path'; doSomething($fullPath); } But I am getting NULL as the value of $ge_path. Why am I not able to access the global variable defines in settings.php? How can I get the proper value inside my module functions? The funny thing is, I am able to access $db_url['default'] and $db_url['mydatabase'] etc.. which are defined just two lines above $ge_path in settings.php!
