  • Log the method name in objective-C?

    - by vodkhang
    Currently, we are defining ourselves an extended log mechanism to print out the class name and the source line number of the log. #define NCLog(s, ...) NSLog(@"<%@:%d> %@", [[NSString stringWithUTF8String:__FILE__] lastPathComponent], \ __LINE__, [NSString stringWithFormat:(s), ##__VA_ARGS__]) For example, when I call NCLog(@"Hello world"); The output will be: Hello world Now I also want to log out the method name like: Hello world So, this would make our debugging become easier when we can know which method is getting called. I know that we also have XCode debugger but sometimes, I also want to do debugging by logging out.

  • IE8 no honoring display:none

    - by user357034
    I have the following markup on a page and unfortunately I do not have direct access to it. . This page is opened in an iframe. There is other code on the page but it is not relevant so I have not posted it. The only access to target the code in via css. I want to not display the close button so I added this to the css file img[alt='Close'] {display:none !important;} this is the markup <td align="center"><a href='javascript:window.close()'><img src='v/vspfiles/templates/100/images/buttons/btn_close.gif' alt='Close' border=0></a></td> It works as expected in all browsers that i have tested (firefox, Opera, Safari) but in IE8 it seems to ignore this css and shows the button. Not sure if it doesn't like the selector or perhaps I have a syntax error. Not sure where to go from here.

  • Problem with mysql query to replace a string

    - by alex
    I've used mysql's update replace function before, but even though I think I'm following the same syntax, I can't get this to work. Here's what I'm trying to do: UPDATE contained_widgets SET preference_values = REPLACE(preference_values, '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li>', '<li><a_href="/enewsletter"><span class="not-tc">eNewsletter</span></a></li> <li> <a_href="/projects"><span class="not-tc">Projects</span></a></li>'); Query OK, 0 rows affected (0.00 sec) Rows matched: 77 Changed: 0 Warnings: 0 I don't see what I'm missing. Any help is appreciated. I edited "a " to "a_" because the site thinks I'm posting spam links otherwise.

  • How does Twitter for iPhone bookmarklet work?

    - by Igor Zevaka
    Twitter client (formerly Tweetie) allows you to define a bookmarklet in Safari that launches the app. I want to know which iPhone API allows you to register the protocol specifier (or whatever it's called) - in this case "tweetie:" - in order for this bookmarklet to work. The instructions can be found here and the bookmarklet itself is below. javascript:window.location='tweetie:'+window.location Clicking the above bookmark is the same as typing in "tweetie:http://google.com" into the address bar. This is obviously supported on the OS/Browser level, much the same as tel: URIs. Am I correct in understanding that developers can add arbitrary URI protocol specifiers as a part of app installation?

  • Where to start with C#

    - by RobertPitt
    Hello fellow programmers. Im a pretty experienced programmer in PHP and mainly web languages but today i have decided i want to start to learn a new language! Im only 21 and I feel as I will never make it in the programming industry without a great set of languages under my belt, So i decided to have a look at C#. The reason I have chosen C# is because some C programmers have told me that C# is the best language to learn for desktop applications. I think i need to get started with the Syntax / Structure of C#, What Development Environment to use, and other things that i might face along my new journey. I hope somebody can guide me Thanks.

  • Vendor neutral SQL

    - by Sparafusile
    I'm currently working on a project for a web application that may be installed on several different servers with various software configurations. I want to make my application as flexible as possible by allowing the user to have various SQL servers installed. The problem is the SQL syntax used by any two server vendors does not match up. For a simple example, here is the same SELECT statement for MS SQL and MySQL: MS SQL - SELECT TOP 1 * FROM MyTable ORDER BY DateCreated DESC MySQL - SELECT * FROM MyTable ORDER BY DateCreated DESC LIMIT 1 Are there any standard way to abstract the statement creation for various vendors? Any online resources or books discussing this problem? Any hints or smart-alec remarks that I'd find useful? Further information: I'm writing my we application in vanilla ASP running on a Windows server. Thanks, Spara

    - by Jan
    is there a way to hide specific buttons (IBAction) when making a screenshot with UIGraphicsBeginImageContextWithOptions ? I'm using the code below: // Define the dimensions of the screenshot you want to take (the entire screen in this case) UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0); [self.view.layer renderInContext:UIGraphicsGetCurrentContext()]; UIImage *sourceImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); //now we will position the image, X/Y away from top left corner to get the portion we want UIGraphicsBeginImageContextWithOptions(self.view.bounds.size, self.view.opaque, 0.0); [sourceImage drawAtPoint:CGPointMake(0, -20)]; UIImage *croppedImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); UIImageWriteToSavedPhotosAlbum(croppedImage,nil, nil, nil); Thank you for your answer!

    I have been searching for several hours regarding how to create a user using SQL for a database I am building in Access.

However, whenever I attempt to run the query, an error saying Syntax error in CREATE TABLE statement pops up. What am I doing wrong? Thank you in advance for your help! If you're interested, the code format I am attempting to use is as follows: CREATE USER username, password, pid.

  • Problem compiling bison & flex program under vc++

    - by Eric
    I'm using bison & flex (downloaded via cygwin) with vc++. When I compile the program I got an error: ...: fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory The corresponding code in the flex-generated file is: #ifndef YY_NO_UNISTD_H /* Special case for "unistd.h", since it is non-ANSI.

  • Extract Generic types from extended Generic

    - by Brigham
    I'm trying to refactor a class and set of subclasses where the M type does extend anything, even though we know it has to be a subclass of a certain type. That type is parametrized and I would like its parametrized types to be available to subclasses that already have values for M. Is there any way to define this class without having to include the redundant K and V generic types in the parameter list. I'd like to be able to have the compiler infer them from whatever M is mapped to by subclasses. public abstract class NewParametrized<K, V, M extends SomeParametrized<K, V>> { public void someMethodThatTakesKAndV(K k1, V v1) { } } In other words, I'd like the class declaration to look something like: public class NewParametrized<M extends SomeParametrized<K, V>> { And K and V's types would be inferred from the definition of M.

  • linq to sql using foreign keys returning iqueryable(of myEntity]

    - by Gern Blandston
    I'm trying to use Linq to SQL to return an IQueryable(of Project) when using foreign key relationships. Using the below schema, I want to be able to pass in a UserId and get all the projects created for the company the user is associated with. DB tables: Projects Projid ProjCreator FK (UserId from UserInfo table) Companyid FK (CompanyID from Companies table) UserInfo UserID PK Companyid FK Companies CompanyId PK Description I can get the iqueryable(of project) when simply getting the ProjectCreator with this: Return (From p In db.Projects _ Where p.ProjectCreator = Me.UserId) But I'm having trouble getting the syntax to get a iqueryable(of projects) when using foreign keys. Below gives me an IQueryable(of anonymous) but I can't seem to convince it to give me an IQueryable(of project) even if I try to cast it: Dim retval = (From p In db.Projects _ Join c In db.Companies On p.CompanyId Equals c.CompanyId _ Join u In db.UserInfos On u.CompanyId Equals c.CompanyId _ Where u.Login = UserId)

  • How does tomcat set its executable file as a windows service?

    - by Wing C. Chen
    Firstly, I am not at all familiar with windows batch file programing. Recently I am curious about how tomcat sets itself as a windows service using a batch file. I downloaded the service.bat file from tomcat 6. However, I still don't understand some part of it. I guess this is the line that the batch actually register the exe file to the OS, is it right? Is there any syntax explanation? "%EXECUTABLE%" //IS//%SERVICE_NAME% --StartClass org.apache.catalina.startup.Bootstrap --StopClass org.apache.catalina.startup.Bootstrap --StartParams start --StopParams stop And is this used to remove the service? "%EXECUTABLE%" //DS//%SERVICE_NAME% And this is the setting of the parameters? "%EXECUTABLE%" //US//%SERVICE_NAME% --JvmOptions "-Dcatalina.base=%CATALINA_BASE%;-Dcatalina.home=%CATALINA_HOME%;-Djava.endorsed.dirs=%CATALINA_HOME%\endorsed" --StartMode jvm --StopMode jvm Thanks.

  • Is C# 4.0 Tuple covariant

    - by RichK
    (I would check this out for myself, but I don't have VS2010 (yet)) Say I have 2 base interfaces: IBaseModelInterface IBaseViewInterface And 2 interfaces realizing those: ISubModelInterface : IBaseModelInterface ISubViewInterface : IBaseViewInterface If I define a Tuple<IBaseModelInterface, IBaseViewInterface> I would like to set that based on the result of a factory that returns Tuple<ISubModelInterface, ISubViewInterface>. In C# 3 I can't do this even though the sub interfaces realize the base interfaces. And I'm pretty sure C# 4 lets me do this if I was using IEnumerable<IBaseModelInterface> because it's now defined with the in keyword to allow covariance. So does Tuple allow me to do this? From what (little) I understand, covariance is only allowed on interfaces, so does that mean there needs to be an ITuple<T1, T2> interface? Does this exist?

  • nhibernate : mapping to column other than primary key

    - by frosty
    I have the following map. My intention is for the order.BasketId to map to orderItem.BasketId. Tho when i look at the sql i see that it's mapping order.Id to orderItem.BasketId. How do i define in my order map which order property to map against basketId. It seems to default to the primary key. <property name="BasketId" column="Basket_ID" type="Int32"/> <set name="OrderItems" table="item_basket_contents" generic="true" inverse="true" > <key column="Basket_ID" /> <one-to-many class="EStore.Domain.Model.OrderItem, EStore.Domain"/> </set>

  • Suggestion for R/LaTeX table creation package

    - by aL3xa
    I've been using xtable package for a long time, and looking forward to writting my first package in R... so I reckon that if I have some "cool" idea that's worth carying out, there's a great chance that somebody got there before me... =) I'm interested in functions/packages specialized for LaTeX table creation (through R, of course). I bumped on quantreg package which has latex.table function. Any suggestion for similar function(s)/package(s)? P.S. I'm thinking about building a webapp in which users can define their own presets/templates of tables, choose style, statistics, etc. It's an early thought, though... =)

  • What's the VB.NET equivalent of this C# code for wiring up and declaring an event?

    - by Ben McCormack
    I'm working on a tutorial to build a media player in Silverlight and am trying to wire up an EventHandler to the timer.Tick event of a DispatchTimer object so that the time of the video is synced with a Slider object. The sample code is in C# and I can't for the life of me figure out the proper syntax in VB.NET with RaiseEvent and/or Handles to wire up the event. Below is the relevant C# code. I'll include comments on where I'm getting stuck. private DispatchTimer timer; public Page() { //... timer = new DispatchTimer(); timer.Interval = TimeSpan.FromMilliseconds(50); timer.Tick += new EventHandler(timer_Tick); // <== I get stuck here b/c // I can't do "timer.Tick += ..." in VB.NET } void timer_Tick(object sender, EventArgs e) { if (VideoElement.NaturalDuration.TimeSpan.TotalSeconds > 0) { sliderScrubber.Value = VideoElement.Position.TotalSeconds / VideoElement.NaturalDuration.TimeSpan.TotalSeconds; } }

  • Help! How to get the event handler with IE Dom interfaces?

    - by usfree74
    Hey Gurus, I am working to use IE Dom interface to automate IE page access. I am trying to get all event handlers defined in a page. I am using IHTMLElement object now for this purpose. If the html page defines "onclick=xxx", element.onclick returns the click handler. However, if an event handler is defined in javascript, element.onclick simply returns NULL. What's the right way to get the event handler then? Thanks, xin Below is an example that uses javascript to define event handler. $(document).ready(function(){ $("a").click(function(event){ $(this).hide("slow"); alert("Thanks for visiting!"); window.location="http://cnn.com"; }); }); jQuery

  • Customizing UISlider look

    - by tcurdt
    To customize the visual look of a UISlider you can set the thumb and track images. Part of the track images gets stretched to the appropriate with. From the documentation: A stretchable region sits between two end cap regions. The end caps define the portions of the image that remain as is and are not stretched. The stretchable region is a 1-point wide area between the end caps that can be replicated to make the image appear longer. Now the problem I have is that my stretchable region needs to be more than 1-point wide. (It's a pattern) Unfortunately the 1-point width seems to be hard coded in the SDK. Anyone having an idea how to work around this? Or will I have to write my own slider from scratch for this?

This surely works, but: I want to use the @MessageDriven annotation I want the setting not to be global for the application server I want the setting to be portable

  • STL Static-Const Member Definitions

    - by javery
    How does the following work? #include <limits> int main() { const int* const foo = &std::numeric_limits<int> ::digits; } I was under the impression that in order to take an address of a static const-ant member we had to physically define it in some translation unit in order to please the linker. That said, after looking at the preprocessed code for this TU, I couldn't find an external definition for the digits member (or any other relevant members). I tested this on two compilers (VC++ 10 and g++ 4.2.4) and got identical results (i.e., it works). Does the linker auto-magically link against an object file where this stuff is defined, or am I missing something obvious here?
