  • iphone - double tap fail safe way

    - by mike
    I am trying to detect double taps on a view, but when the double tap comes, the first tap triggers an action on TouchesBegan, so, before detecting a double tap a single tap is always detected first. How can I make this in a way that just detects the double tap? I cannot use OS 3.x gestures, because I have to make it compatible with old OS versions. thanks

  • Long overdue (for me) question about disposing managed objects in .Net, VB.Net, C#

    - by Jules
    I can't believe I'm still confused about this but, any way, lets finally nail it: I have a class that overrides OnPaint to do some drawing. To speed things up, I create the pens, brushes etc before hand, in the construtor, so that OnPaint does not need to keep creating and disposing them. Now, I make sure that I always dispose of such objects, but I have the feeling I don't need to because, despite the fact they implement IDisposable, they're managed objects. Is this correct?

  • Abstraction is for lame programmers ? [closed]

    - by Zaban Khuli
    Hi, there's this senior developer in my company who's (in his own opinion) a pretty good C programmer. I happen to be from functional background (ML, to be specific) and so for me composition and abstraction are the two basic elements of programming. But this MrSmartyPants has got some kind of superiority complex and he'd always argue with me that abstraction is for lame programmers and _real_ programmers do not need it. Is it a problem with this guy or all C programmers have this opinion that abstraction is for lame programmers?

    - by SDReyes
    Hi guys, I have two SQL Server 2008 databases called Anna and Bob. Bob has to pull and transform data from Anna to keep updated his tables. Ideally Bob will be always synchronized with Anna, but some delay would be acceptable. What is the best way to do this? Thanks in advance.

  • Is it possible to prevent just horizontal scrolling when overflow-x is hidden?

    - by Andrew LeClair
    I have a web page that has content which extends past the right edge of the browser window. I set overflow-x: hidden on <body> to turn off the bottom scrollbar, but I can still scroll horizontally with the trackpad, which is not what I want. Is there any way to prevent the browser from scrolling horizontally? As a side note: Safari 4.0.4 only scrolls horizontally sometimes, and the scrolling feels "sticky" and "jumpy," whereas Firefox always smoothly scrolls horizontally.

  • When is lazy evaluation not useful?

    - by Cherian
    Delay execution is almost always a boon. But then there are cases when it’s a problem and you resort to “fetch” (in Nhibernate) to eager fetch it. Do you know practical situations when lazy evaluation can bite you back…?

  • Read excel 2007 file with OLEDB using a specific culture

    - by Derek Ekins
    I am trying to read an excel 2007 file (using OLEDB) that has dates in the UK format. The server is (sometimes) set to US format and so the normal date format problems are in play. This is my connection string: Provider=Microsoft.ACE.OLEDB.12.0;Data Source=myfile.xlsx;Extended Properties="Excel 12.0 Xml;HDR=NO;IMEX=1" I want to ensure that the file is always opened using the en-GB culture. Is there a way to specify the culture using the connection string?

  • Black hat knowledge for white hat programmers

    - by Dinah
    There's always skepticism from non-programmers when honest developers learn the techniques of black hat hackers. Obviously though, we need to learn many of their tricks so we can keep our own security up to par. To what extent do you think an honest programmer needs to know the methods of malicious programmers?

  • EXT-GWT Portal: How to get all Portlets?

    - by Lars
    Hi all this is my first Question here! Im just making my first steps with (Ext-) GWT. I´m testing the Ext-GWT libraries and really: These are absolute great! Now my question: Is it possible to make a kind of "clear-Portal" or "hide all portles" for a defined Portal? Or have i always manually clear the portal like in my example code above? My sample code looks like this: //define the Portal, 2 columns, each 50% auf width, with borders and Backgroundcolor portal = new Portal(2); portal.setBorders(true); portal.setStyleAttribute("backgroundColor", "white"); portal.setColumnWidth(0, .50); portal.setColumnWidth(1, .50); //define a Portlet for showing all Users portletUser = new Portlet(); portletUser.setHeading("Benutzer"); configPanel(portletUser); portletUser.setLayout(new FitLayout()); CompUserList compUserList = new CompUserList(); portletUser.add(compUserList); portletUser.setHeight(250); //define a Portlet for showing all Vehicles portletVehicles = new Portlet(); portletVehicles.setHeading("Fahrzeuge"); configPanel(portletVehicles); portletVehicles.setLayout(new FitLayout()); CompVehicleList compVehicleList = new CompVehicleList(); portletVehicles.add(compVehicleList); portletVehicles.setHeight(250); //define a portlet for showing all countries portletCountries = new Portlet(); portletCountries.setHeading("Länder"); configPanel(portletCountries); portletCountries.setLayout(new FitLayout()); CompCountryList compCountryList = new CompCountryList(); portletCountries.add(compCountryList); portletCountries.setHeight(250); //add both Portlets to Portal portal.add(portletUser, 0); portal.add(portletVehicles, 1); So first of all this works fine and looks great :-) Now i have a a button in a accordeon menu. The Listener on this button should hide all portlets in the portal (at this time its the portletUser and portletVehicles) and then add another portlet (for example the portletCountries): portletUser.hide(); portletVehicles.hide(); portal.add(portletCountries, 0) Question from above again ;-) Is it possible to make a kind of "clear-Portal" or "hide all portles" for a defined Portal? Or have i always manually clear the portal like in my example code above? What is the best practice for this functionallity? Thanks all for your tips! Lars.

  • How to update maven repository in eclipse?

    - by Stephane Grenier
    Assuming you're already using the m2eclipse plugin, what can you do it doesn't update the dependencies to the latest in your repo. For example, on the command line you can just add the -U flag as in: mvn clean install -U to force the dependencies to be updated. Is there something like this within eclipse since it doesn't always seem to pick up the latest updates.

  • ModelVisual3D vs Model3DGroup

    - by bitbonk
    Is there any disadvantage of using ModelVisual3D over Model3DGroup. How much can the resource/performance impact possibly be? ModelVisual3D gives me much more than Model3DGroup does but AFAIK everything that can be done with Model3DGroup can alos be done with ModelVisual3D. So why not just always use ModelVisual3D?

  • Does the asp.net RoleManager really cache the roles for a user in a cookie if so configured?

    - by Ralph Shillington
    In my web.config I have the Role Manager configured as follows: <roleManager enabled="true" cacheRolesInCookie="true" cookieName=".ASPROLES" cookieTimeout="30" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" cookieProtection="All"> however in our custom RoleProvider it would seems that the GetRolesForUser method is always being called, rather than as I would have expected, the RoleManager serving up the roles from its cookie. We're using something like to get the roles for a user: string[] myroles = Role.GetRolesForUser("myuser"); Is there something that I'm missing in the configuration, or in the use of the RoleManager Thanks in advance

  • ActiveRecord + CodeIgniter - Return single value from query, not in array form.

    - by txmail
    Say you construct an activerecord query that will always just return a single value, how do you just address that single value instead of getting an array in return? For instance I am using an ActiveRecord query to return the SUM of a single column, it will only return this one single SUM, instead of having to parse the array is there a way to assign the value as a function return equal to that value instead of getting an array?

  • using htmlpurifier for input or output escaping/filtering

    - by user214545
    I am processing a user input from the public with a javascript WYSIWYG editor and I'm planning on using htmlpurifier to cleanse the text. I thought it would be enough to use htmlpurifier on the input, stored the cleaned input in the database,and then output it without further escaping/filtering. But I've heard other opinions that you should always escape the output. Can someone explain why I should need to cleans the output if I'm already cleaning the input?

  • Using Selenium, how can I test a web UI that returns XML instead of HTML?

    - by Kurt W. Leucht
    I'm using Selenium to unit test my Perl cgi script and all works fine except in one case where my cgi script returns XML content to the web browser instead of returning HTML content. I'm new to Selenium and only pasted in their sample script to get started, but I can't seem to find a Selenium command in any of the documentation that will recognize that my XML response has been returned. The Selenium commands seem to assume that an HTML page is always being returned.
