  • Embedded Lua on iPhone. What's new and what does it mean?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

  • iPhone How to set a clearcolor for my custom view

    - by user355066
    Hi, I am creating a custom StyleLabel by extending the UIView, which provides a link for particular type of strings. I have successfully implemented this functionality. I am using this label in TableViewCell along with UILabel.i set UILabel & StyleLabel background color is set to clearColor. UILabel works fine, but StyleLabel shows background in blackColor. I am not sure what is the problem with the following code. Here is the drawRect method of CustomLabel class -(void) drawRect:(CGRect)rect { CGContextRef ctx = UIGraphicsGetCurrentContext(); CGContextClearRect(ctx, rect); [[UIColor clearColor] setFill]; CGContextAddRect(ctx, rect); CGContextDrawPath(ctx, kCGPathFill); [_text drawText:ctx]; } Thanks Sasikumar

  • QT4, paginated showing elements

    - by matiit
    I am going to write an application that uses QT4 (with C++ or python it isnt important in that moment). One of functionality is "Showing all items in database". One item has a Title, author, description and photo (constant size) And there could be very many items. Let's say 400. There won't be enough space to show'em all at once time. One row will have 200px, so i need at most 4 for once time. How to paginate them? I have no idea. I can use limit and offset in SQL queries, but how to tell window: "that's 5th page"? Any solutions?

  • How to build a private "Google Apps Marketplace" apps for gmail intergration like Rapportive does

    - by Hans Klock
    Google Apps Marketplace (http://www.google.com/enterprise/marketplace/) has enabled contextual gadgets so I could integrate my functionality in gmail. I would like to do so but I don't want to publish the app. Is this possible? (http://developer.googleapps.com/marketplace/getting-started tells me I have to become a vendor.) If I can do so I can't find any example code how to integrate in gmail, e.x. access a message, add a button, ... BTW: Greasemonkey is NOT an option.

  • When to rewrite vs. upgrade?

    - by MrGumbe
    All custom legacy software needs changing, or so say our users. Sometimes they want a feature or two added and all that is necessary to change a bit of code, add a control, or some other minor upgrade task. Sometimes they want to ditch their error-prone VB5 desktop solution and rewrite the whole thing as a rich Web 2.0 ASP.NET MVC application. More often, however, the scope of changes to legacy functionality lies somewhere between these two extremes. What rules of thumb to you use to decide whether you should upgrade an existing application or start from scratch?

  • Bug Tracker - Feature set - Comparison

    - by Blankman
    Hi, I have installed and played around with a few bug tracking apps, and just wanted to get some feedback and features that a typical (or not so typical) bug tracking software has. I want to make sure I am not overlooking a feature that might come in handy. So the biggest idea is around a bug, which is associated with: Bugs - product - product version - component (specific component of the product) - status - priority - assigned to - expected time to finish - time spent on it so far - created by - historical log of bug Forums Wiki I guess the above functionality is common to all, so what exactly differentiates them? Is it simply the UI and filtering/searching that you base a decision on? (I am comparing something like Jira with FogBugz)

  • Developing a project which is an implementation of an open standard/protocol

    - by dotnetdev
    Hi, A lot of interesting code/projects are implementations of protocols, eg SNMP. How are projects like these, which depend on implementing a certain format, developed? Is the process something like get the guidelines of the protocol and then implement code which follows it. For example, XML-RPC is about transmitting XML docs between client/server, so the documentation on this protocol must outline the structure of the XML documents and then the way the transportation between client and server works, so the coder will implement this sort of functionality (xml doc construction, networking between the client and server). Projects I am thinking of (not to develop) are C# libraries which can interpret .PSDs, make VHDs, etc. So if I was to develop a C# app to implement .AI files (Illustrator files), what would be the steps I would look at (such as contacting Adobe, etc)? Is this the way such projects are developed?

  • Open source framework à la Microsoft Sync Framework suggestions?

    - by drskol
    We are implementing a warehouse management system atop an open source stack (Java, web services & friends). In this system, we want to integrate many mobile devices which should also be capable of adequate online/offline functionality, e.g. preparing database inserts while a mobile device is temporarily unconnected, and performing them on the backend database when reconnected. For a .NET stack, Microsoft Sync Framework would be a perfect solution, e.g. to do database replication and hoarding. Can anyone suggest an open source alternative to the MS Sync Framework and possibly describe his experiences with it? Thanks in advance for any answers.

  • Firebug is permanently inactive

    - by bwb
    Firebug used to work fine -- until something happened -- not sure what. FF 3.6.3 on XP PRo current. The net effect is Firebug is now always inactive. The icon is present and gray as is normal. Click on the icon and I get: It does this regardless of the site. I've uninstalled Firebug and re-installed. nada. Additionally, the Tools Firebug menu yields nothing. The only unusual issue I can think of is it may of stopped working sometime after I created an additional FF profile (which has since been removed) for a test. Somehow, in removing the extra profile, my bookmarks were deleted. I recovered them from by my online-backup service. Any suggestions? I'd really like to get the Firebug functionality back. thanks.

  • Is it weird or strange to make multiple WCF Calls to build a ViewModel before presenting it?

    - by Nate Bross
    Am I doing something wrong if I need code like this in a Controller? Should I be doing something differently? public ActionResult Details(int id) { var svc = new ServiceClient(); var model = new MyViewModel(); model.ObjectA = svc.GetObjectA(id); model.ObjectB = svc.GetObjectB(id); model.ObjectC = svc.GetObjectC(id); return View(model); } The reason I ask, is because I've got Linq-To-Sql on the back end and a WCF Service which exposes functionality through a set of DTOs which are NOT the Linq-To-Sql generated classes and thus do not have the parent/child properties; but in the detail view, I would like to see some of the parent/child data.

  • Walking through an SQLite Table

    - by galford13x
    I would like to implement or use functionality that allows stepping through a Table in SQLite. If I have a Table Products that has 100k rows, I would like to retrive perhaps 10k rows at a time. Somthing similar to how a webpage would list data and have a < Previous .. Next > link to walk through the data. Are there select statements that can make this simple? I see and have tried using the ROWID in conjunction with LIMIT which seems ok if not ordering the data. // This seems works if not ordering. SELECT * FROM Products WHERE ROWID BETWEEN x AND y;

  • WPF: how to make normal listbox left-drag-select behavior use middle mouse instead?

    - by Scott Bilas
    I'm building a special listbox control that our designers want customized in some tweaky ways. One thing they want to see is that the middle button-drag does what the left button-drag normally does (we are repurposing left-drag to other things). So it needs the two key features that left-drag does in a ListBox default implementation: While holding down the button and dragging, the selection starts where I click down and extends to where I drag. While dragging outside the listbox region, it scrolls if there is scrollable space in that direction. Before I go an duplicate this functionality by hand, is there any easy way to fool ListBox into thinking it's getting left-mouse drag events but instead is getting middle-mouse?

  • FastCGI has to be restarted for new content to be displayed on my Django site

    - by vorpyg
    I'm currently testing serving my Django site with Nginx, FastCGI and Flup. The server is configured roughly as described in the Django Advent article. I had to do some minor modifications in order to make it work in Ubuntu 9.10. The problem is that when I add new content it doesn't show up on the page before I restart the FastCGI process. I haven't enabled any caching functionality in Django, and when I query the DB from the Django shell it works as expected. Anybody got ideas to what's causing this?

  • Wpf button click when application window is not active

    - by byte
    I have a WPF application window with a button (ButtonA) which has a command binding to a View Model property. When another application is launched the focus is lost and application window is deactivated. Clicking ButtonA now doesn’t execute the command but instead only activates the window and sets the focus to the button. 2nd click is required to fire the command. The desired functionality is on click of ButtonA while the application window is not active, the application window activates and command associated with ButtonA is executed. I have also tried removing the command and adding a click handler for test purpose but this displays same behaviour. I appreciate any help with this issue.

  • Creating An OLEDB Connection From Excel To SQL

    - by Soo
    I am looking to run SQL queries using VBA code in an Excel file. It may sound like a bad way to do things, but the purpose of this is to support legacy functionality on a project I'm working on. I figured out how to create an ODBC connection, but it requires several steps which may be troublesome to implement on many computers, so I'm looking into the possibility of using OLEDB to get the job done. My question is how to go about setting things up so I can run SQL queries in Excel using VBA.

  • Simple graphics API with transparency, polygons, reading image pixels?

    - by M. Elkstein
    I need a simple graphics library that supports the following functionality: Ability to draw polygons (not just rectangles!) with RGBA colors (i.e., partially transparent), Ability to load bitmap images, Ability to read current color of pixel in a given coordinate. Ideally using JavaScript or Python. Seems like HTML 5 Canvas can handle #2 and #3 but not #1, whereas SVG can handle #1 and #2 but not #3. Am I missing something (about either of these two)? Or are there other alternatives?

  • Basic Python While loop compound conditional evaluation

    - by dbjohn
    In Python IDLE Shell it seems I cannot use a compound conditional expression and a while loop. I tried it within brackets too. k=0 m=0 while k<10 & m<10: print k k +=1 m+=1 If I write while k<10: print k k+=1 This does work. Is there a way I could achieve the first block of code with the "and" operator. I have done it in Java. Do I just need to put together "if" statements to achieve the same functionality in Python?

  • Mixing expressions and expression language (<%= %> inside of c:if)

    - by Jack
    I need to access some constants in my jsp, and sadly the EL does not offer any functionality for it. There are some options like the unstandard tag library, but I'd like to keep it a bit more standard. I tried: <%@ page import = "com.jackdane.Constants"%> <c:if test="${object.display == '<%=com.jackdane.Constants.YES %>}'"> //some display logic </c:if> But that doesn't appear to do the trick. It's been a while since I've used an expression so I might have made an error. Any input is appreciated. Edit: To clarify, the constants class is not in my control. It's inside a jar file that I recieved. It contains no getters/setters. Just private static final Strings.

  • clear cached javascript includes in FireFox

    - by user151841
    I'm working on javascript for a site, developing with FireFox, and when I refresh the page, I don't see my changes. The javascript file is in an external file. I reloaded and refreshed the page several times, but the old javascript file was still cached. Finally, I loaded the javascript page in the browser directly, saw the old script, hit 'reload', and saw my changes. How can I clear cached external javascript files? I'll need to know this also when I tell the client that the changes are made, so that they aren't seeing the old cached functionality.

  • iPhone UIImage Display Controller

    - by Bill Shiff
    Hello, I would like to be able to display a UIImage from within my app and support a lot of the functionality available in the built-in Photos app (i.e., pinch-to-zoom, pan, etc). I don't really want to write a bunch of code that someone has already written, so I'm wondering if there is a library out there already that I could just import into my project. I'm aware of the Three20 project, but I don't want to import a huge library if I don't have to. Is anyone aware of an available library that's already out there for displaying UIImages? Or part of some open-source project that can be pulled out on its own? Thanks!

  • Is it possible to avoid C++ compiler error (C2757) where 2 different header files contain same symbol for namespace & class?

    - by dharmendra
    Hi, I am facing a problem when implementing some new code to an existing library. This library already references a class with a name say 'foo'. The same name is used as a namespace in the other header file which has to be included to implement the new functionality. Since both the header files are a part of legacy code libraries I cannot amend them. So here I am looking for any way so as to avoid the Compiler Error (C2757: a symbol with this name already exists and therefore this name cannot be used as a namespace name). I am not sure whether it is possible or not. Hence, Any help shall be appreciated. Thanks For clarity here is the sample code illustration for the issue: HeaderA.h class foo {} HeaderB.h namespace foo { class ABC{} } HeaderC.h #include <HeaderA.h> #include <HeaderB.h> using namespace foo; class Toimplement{ ABC a; //Throws Error C2757 }

  • Call javascript function from Java (Groovy) class

    - by ashkanr
    Hi, I have a javascript function (very big one!) that I need its functionality in a Java (Groovy) class. It is a simple calendar converter. I can rewrite it in groovy but just want to know if it is possible to call javascript function from a java (groovy) method? I guess functional testing libraries like selenium and Canoo should have something like this, am I right? PS: I don't want to wake up a real-world browser in order to use its JS runtime env. Thanks,
