  • PHP: Escape illegal chars in .ini-files

    - by Martin
    The documentation on parse_ini_file (http://php.net/manual/en/function.parse-ini-file.php) states that you can't use these chars {}|&~![()^" in the value. Is there some way to escape these chars? I need to use them. Normal escaping with \ doesn't seem to work.

  • Rearrange a python list into n lists, by column

    - by Ben R
    Trying to solve this at this hour has gotten my mind into a tail-spin: I want to rearrange a list l into a list of n lists, where n is the number of columns. e.g., l = [1,2,3,4,5,6,7,8] n = 5 ==> [[1,6][2,7][3,8][4][5]] another example: l = [1,2,3,4,5,6,7,8,9,10] n = 4 ==> [[1,5,9],[2,6,10],[3,7][4,8] Can someone please help me out with an algorithm? Feel free to use any python awesomeness that's available; I'm sure theres some cool mechanism that's a good fit for this, i just can't think of it.

  • How do I "rebind" the click event after unbind('click') ?

    - by Ben
    I have an anchor tag <a class="next">next</a> made into a "button". Sometimes, this tag needs to be hidden if there is nothing new to show. All works fine if I simply hide the button with .hide() and re-display it with .show(). But I wanted to uses .fadeIn() and .fadeOut() instead. The problem I'm having is that if the user clicks on the button during the fadeOut animation, it can cause problems with the logic I have running the show. The solution I found was to unbind the click event from the button after the original click function begins, and then re-bind it after the animation is complete. $('a.next').click(function() { $(this).unbind('click'); ... // calls some functions, one of which fades out the a.next if needed ... $(this).bind('click'); } the last part of the above example does not work. The click event is not actually re-bound to the anchor. does anyone know the correct way to accomplish this? I'm a self-taught jquery guy, so some of the higher level things like unbind() and bind() are over my head, and the jquery documentation isn't really simple enough for me to understand.

  • Sqlite + Java: table not updating

    - by Ben L
    I'm using a Java wrapper for SQLite called SQLiteJDBC - this may have some bearing on any answers... I have a table which I've displayed in a GUI, within that UI I have a button for the fields for an individual row of that table. When I save my changes I do this... Statement stmt = connection.createStatement(); stmt.execute("update 'tableName' set 'fieldName'=1 where userid=1"); int updateCount = stmt.getUpdateCount(); My connection is valid, I get no exceptions thrown and getUpdateCount() returns '1' indicating that one row has been updated. However my table is not updated. I've spent the last few hours trying to work out what's going on but I'm not having any luck. Help!!

  • C++ String tokenisation from 3D .obj files

    - by Ben
    I'm pretty new to C++ and was looking for a good way to pull the data out of this line. A sample line that I might need to tokenise is f 11/65/11 16/70/16 17/69/17 I have a tokenisation method that splits strings into a vector as delimited by a string which may be useful static void Tokenise(const string& str, vector<string>& tokens, const string& delimiters = " ") The only way I can think of doing it is to tokenise with " " as a delimiter, remove the first item from the resulting vector, then tokenise each part by itself. Is there a good way to do this all in one?

  • Converting code to perl sub, but not sure I'm doing it right

    - by Ben Dauphinee
    I'm working from a question I posted earlier (here), and trying to convert the answer to a sub so I can use it multiple times. Not sure that it's done right though. Can anyone provide a better or cleaner sub? sub search_for_key { my ($args) = @_; foreach $row(@{$args->{search_ary}}){ print "@$row[0] : @$row[1]\n"; } my $thiskey = NULL; my @result = map { $args->{search_ary}[$_][0] } # Get the 0th column... grep { @$args->{search_in} =~ /$args->{search_ary}[$_][1]/ } # ... of rows where the 0 .. $#array; # first row matches $thiskey = @result; print "\nReturning: " . $thiskey . "\n"; return $thiskey; } search_for_key({ 'search_ary' => $ref_cam_make, 'search_in' => 'Canon EOS Rebel XSi' });

  • Nested functions not allowed in drawrect problem

    - by Martin
    I have a custom view onto which I draw some graphics from the drawrect function, which works fine. However I like to draw based on the contens of an array I pass on the the view just before I do a setNeedsDisplay. In the drawRect function I try to access the array but then I get a nested functions error which I do not understand. Here's my code: // // MyView.h // window // #import <UIKit/UIKit.h> @interface MyView : UIView { NSArray * nary; } @property (nonatomic, copy) NSArray *nary; @end // // MyView.m // window // #import "MyView.h" @implementation MyView @synthesize nary; CGContextRef c; CGFloat black[4] = {0.0f, 0.0f, 0.0f, 1.0f}; - (id)initWithFrame:(CGRect)frame { if (self = [super initWithFrame:frame]) { // Initialization code } return self; } - (void)drawRect:(CGRect)rect { c = UIGraphicsGetCurrentContext(); CGContextSetStrokeColor(c, black); NSLog(@"mview"); NSArray *ns = [nary objectAtIndex:0]; } - (void)dealloc { [super dealloc]; } @end

  • EF4 + STE: Reattaching via a WCF Service? Using a new objectcontext each and every time?

    - by Martin
    Hi there, I am planning to use WCF (not ria) in conjunction with Entity Framework 4 and STE (Self tracking entitites). If i understnad this correctly my WCF should return an entity or collection of entities (using LIST for example and not IQueryable) to the client (in my case silverlight) The client then can change the entity or update it. At this point i believe it is self tracking???? This is where i sort of get a bit confused as there are a lot of reported problems with STEs not tracking.. Anyway... Then to update i just need to send back the entity to my WCF service on another method to do the update. I should be creating a new OBJECTCONTEXT everytime? In every method? If i am creaitng a new objectcontext everytime in everymethod on my WCF then don't i need to re-attach the STE to the objectcontext? So basically this alone wouldn't work?? using(var ctx = new MyContext()) { ctx.Orders.ApplyChanges(order); ctx.SaveChanges(); } Or should i be creating the object context once in the constructor of the WCF service so that 1 call and every additional call using the same wcf instance uses the same objectcontext? I could create and destroy the wcf service in each method call from the client - hence creating in effect a new objectcontext each time. I understand that it isn't a good idea to keep the objectcontext alive for very long. Any insight or information would be gratefully appreciated thanks

  • OnPaint event during a callback when the form is below?

    - by Martín Marconcini
    Imagine the following scenario: this.SetStyle(ControlStyles.UserPaint, true); //this doesn’t change anything … void OpenSomeForm() { SomeForm sf = new SomeForm(); sf.SomeEvent += new … (SomeEventOcurred); sf.ShowDialog(); } private void SomeEventOcurred(…) { OnePanelInThisForm.Invalidate(); } private void OnePanelInThisForm_Paint(object sender, PaintEventArgs e) { DoSomeDrawing(e.Graphics); } Now, OnePanelInThisForm draws correctly when the form loads. But if SomeEventOcurred is Fired from “SomeForm”, the paint event is not fired. If I close and reopen the form it correctly repaints. If I add a button to the form that executes: OnePanelInThisForm.Invalidate(); the panel is correctly repaint. What am I missing?

  • Can I ReRender the entire tree of a component?

    - by Ben
    Hi, I have a JSF application with several major components and a component tree under each. On a certain event (Value change) I would like to reRender the entire component tree for one of those components. For example: can I rerender components 1,2 and 3 in one shot here: <h:panelgroup id="1"> <h:panelgroup id="2"> <h:panelgroup id="3"> <h:panelgroup/> <h:panelgroup/> <h:panelgroup/> <h:commandButton rerender="1*"> <--- Made up code. Is that possible? Another Idea - Can I reRender with wildcards? (I.E - ReRender all components who's ID's begin or contain: "UpdateMe") Thanks!

  • How do you automatically remove the preview window after autocompletion in Vim?

    - by Ben Davini
    I'm using omnifunc=pythoncomplete. When autocompleting a word (e.g., os.), I get the list of eligible class members and functions, as expected, as well as a scratch buffer preview window with documentation about the selected member or function. This is great, but after selecting the function I want, the preview window remains. I can get rid of it with ":pc", but I'd like it just to automatically disappear after I've selected my function, a la Eclipse. I've played around with "completeopt" but to no avail.

  • XSLT for-each from query results

    - by Ben Record
    I've been on a hunt for a while trying to find a solution to this but I cannot find anywhere that addresses this problem. I'm running a SQL query through XSLT which will return three rows. Here is the query: <query name="OrderedProductNames" rowElementName ="OrderedItem"> <sql> <![CDATA[ select OrderedProductName, Quantity from Orders_ShoppingCart where OrderNumber = 101689 // Hard coded order number for testing purposes. ]]> </sql> </query> Ideally, I would like to iterate through each row returned and do a choose when which is tested on a variable from the current row being inspected in the for-each loop, but I am not entirely sure thhis is possible. My secondary thought would be to use the for-each loop as a way to inject hidden HTML input elements with the values I would need, then I could write a javascript function to complete what I'm trying to do. Any suggestion on how I would go about completing either task would be greatly appreciated.

  • numberOfSectionsInTableView is requested in/after viewDidLoad ONLY if tableview is empty

    - by Ben Packard
    A simple tableviewController, empty. A modal that can be launched from a button. No data in the data source for the tableview, and no rows displayed. I open the modal, use it to add an item, and return to the tableview controller. The tableview updates itself automatically, and the new row is displayed. I add a second item. The table view does NOT update automatically. I can tell by logging inside numberOfSectionsInTableView that even if I go to add the first item and cancel, the tableview refreshes - it asks for the number of sections, rows, and the cell to display (if there is one). But not if there is one pre-existing row in the table. I've scoured my code but can't find anything that would cause the tableview to know when the first item is added, but none afterwards. Any ideas? EDIT - I have further narrowed my issue so will close this shortly and post a more specific question

  • Setting Up TFS Server outside of a domain

    - by Ben
    Hi Im trying to set up TFS 2010 on a machine that is connected to a network, but not on the domain. I am trying to connect this to a SQL Server that is also connected to the network and also not on the domain. When I run through the TFS configuration Wizard and try to connect to the SQL Server, it fails with a message "A connection can not be made...." which looks like it cant see the Server. However when i connect through SQL Management Studio it works when i use SQL Authentication (not Windows Auth). I beleive its failing because TFS needs to connect using Windows Authetication (please correct me if im wrong). I can not add the Windows Authentication for my TFS machine onto the SQL machine becuase they are on different domains (again, pleas correct me if I'm wrong). Does anyone have any suggestions? Thanks.

  • Set background of UITableview in interface builder?

    - by Martin
    In iPhone I need to set the background view of a UITableview. From 3.2 SDK I can in code use something like: [self.tableView setBackgroundView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"mycustombackground.png"]]]; But how can I do the same in interface builder? It would be great if I could just set the background view directly in interface builder. But can't seem to find this property, where is it? Thanks!

  • A simple php form in Joomla?!

    - by Ben Fransen
    Hi all, Someone came to me and asked me if I could add a form to their Joomla page. I figured this should be easy since Joomla is widely used and such thing should be supported. I'm googling arround for 1,5h now, and I have given 4 formcreators a try but this is driving me crazy. The editors are all very complex for the simplest task I want. A simple form with: 5 text input; 1 radio selection criteria; the message a visitor sends. So I've given pretty much up upon formbuilders. Is there a simple way to include an external, self-built very easy php form, into the contactpage? I hope to hear from you... Greetings from Holland

  • How can I share code across static libraries without duplicate symbol errors?

    - by Ben Flynn
    I am new to building static libraries and would like to create 2(+) libraries each of which has some unique code and some shared code. My intention is that other projects will link one or more of these static libraries. Util.h/m <-- Shared ImplOne.h/m <-- Unique to 'ImplOne' ImplTwo.h/m <-- Unique to 'ImplTwo' I am using XCode and generating the libraries by building Util.m and ImplOne.m in one case, and Util.m and ImplTwo.m in the other. Of course the issue is that I now cannot use these libraries together because they will have duplicate symbols. What is a better architecture for this situation?

  • How might a C# programmer approach writing a solution in javascript?

    - by Ben McCormack
    UPDATE: Perhaps this wasn't clear from my original post, but I'm mainly interested in knowing a best practice for how to structure javascript code while building a solution, not simply learning how to use APIs (though that is certainly important). I need to add functionality to a web site and our team has decided to approach the solution using a web service that receives a call from a JSON-formatted AJAX request from within the web site. The web service has been created and works great. Now I have been tasked with writing the javascript/html side of the solution. If I were solving this problem in C#, I would create separate classes for formatting the request, handling the AJAX request/response, parsing the response, and finally inserting the response somehow into the DOM. I would build properties and methods appropriately into each class, doing my best to separate functionality and structure where appropriate. However, I have to solve this problem in javascript. Firstly, how could I approach my solution in javascript in the way I would approach it from C# as described above? Or more importantly, what's a better way to approach structuring code in javascript? Any advice or links to helpful material on the web would be greatly appreciated. NOTE: Though perhaps not immediately relevant to this question, it may be worth noting that we will be using jQuery in our solution.

  • Loop not working when I try to traverse a Simple XML Object

If I change the code within the foreach loop to echo $album->name; it shows nothing at all. What am I doing wrong?
