• Unable to Access UILabel in UITableViewCell

  - by Nirmal

  I am having trouble in accessing which is in the UITableViewCell, that i have placed in my main .xib file. That Label is connected to IBOutlet servicesCell. And the Label inside the table view cell is connected through IBOutlet serviceLabel. At runtime i am not getting the text which i am assining to that label. Following is my sample code for that. static NSString *ServiceIdentifier = @"ServiceIdentifier"; UITableViewCell *cell1 = [tableView dequeueReusableCellWithIdentifier:ServiceIdentifier]; if(cell1 == nil) { [[NSBundle mainBundle] loadNibNamed:@"servicesCell" owner:self options:nil]; cell1 = servicesCell; } // label access serviceLabel = (UILabel *)[cell1 viewWithTag:1]; serviceLabel.numberOfLines = 3; serviceLabel.lineBreakMode = UILineBreakModeWordWrap; [serviceLabel setTextAlignment:UITextAlignmentLeft]; [serviceLabel setText:@"Testing String"]; Anyone have any idea then please help.. Thanks in advance..

• Access variable value using string representing variable's name

  - by Paul Ridgway

  Hello everyone, If the title was not clear, I will try to clarify what I am asking: Imagine I have a variable called counter, I know I can see its current value by doing something like: std::cout << counter << std::endl; However, assume I have lots of variables and I don't know which I'm going to want to look at until runtime. Does anyone know a way I can fetch the value of a variable by using its name, for example: std::cout << valueOf("counter") << std::endl; I feel being able to do this might make debugging large complex projects easier. Thanks in advance for your time.

• NSTableView doesn't populate with array objects until a new object is added via the controller

  - by Luke

  I have an NSTableView and an array controller set up as shown here, using cocoa bindings: https://developer.apple.com/library/mac/documentation/Cocoa/Conceptual/TableView/PopulatingViewTablesWithBindings/PopulatingView-TablesWithBindings.html#//apple_ref/doc/uid/10000026i-CH13-SW3 In my app delegate during applicationDidFinishLaunching I have the following snippet in here, initialising the array and filling it with objects array = [[NSMutableArray alloc] init]; SomeObject* foo = [[Object alloc] init]; foo.text = @"sup"; [array addObject:foo]; //Repeat this a few times However, when I build the app and run it I end up with an empty table. However, if I bind a button to the array controller's add: input and click it during runtime (this adds a new object to the array and table) then the table will show the new object first, with the objects added during applicationDidFinishLaunching following it. Why does this happen? And is there a way to make my table populate without having to add an element first?

• An RMIPRoxyFactoryBean factory in Spring?

  - by Robert Munteanu

  I'm currently using a Spring RmiProxyFactoryBean to access remote services. Since requirements have changed, I need to specify at runtime a different host - there can be many of them - , but the remoteServiceInterface and the non-host components of the remoteServiceUrl remain the same. Conceptually speaking, I'd see a bean definition similar to: <bean class="org.springframework.remoting.rmi.RmiProxyFactoryBeanFactory"> <property name="serviceInterface" value="xxx"/> <property name="serviceUrl" value="rmi://#{HOST}:1099/ServiceUrl"/> </bean> which exposes a Object getServiceFor(String hostName); Is there such a service available with Spring? Alternatively, do you see another way of doing this? Please note that the host list will not be known at compile or startup time, so I can't generate it in the xml file.

• select from multiple tables with different columns

  - by Qaiser Iftikhar

  Say I got this sql schema. Table Job: id,title, type, is_enabled Table JobFileCopy: job_id,from_path,to_path Table JobFileDelete: job_id, file_path Table JobStartProcess: job_id, file_path, arguments, working_directory There are many other tables with varying number of columns and they all got foreign key job_id which is linked to id in table Job. My questions: Is this the right approach? I don't have requirement to delete anything at anytime. I will require to select and insert mostly. Secondly, what is the best approach to get the list of jobs with relevant details from all the different tables in a single database hit? e.g I would like to select top 20 jobs with details, their details can be in any table (depends on column type in table Job) which I don't know until runtime. Thanks in advance. Regards,

• Load python module not from a file

  - by user575061

  Hello, I've got some python code in a library that attempts to load a simple value from a module that will exist for the applications that use this library from somemodule import simplevalue Normally, the application that uses the library will have the module file and everything works fine. However, in the unit tests for this library the module does not exist. I know that I can create a temporary file and add that file to my path at runtime, but I was curious if there is a way in python to load something in to memory that would allow the above import to work. This is more of a curiosity, saying "add the module to your test path" is not helpful :P

• Interesting or unique types encountered?

  - by user318904

  What is the most strange or unique type you have seen in a programming language? I was thinking the other day about a "random variable", ie whenever it is evaluated it yields a random value from some domain. It would require some runtime trickery. Also I bet there can be some interesting mapping of regular expressions into a type system. It does not necessarily have to be a built in or primitive type, but some random class that implements a domain specific type won't really be interesting just unique.

• How to find dynamically loaded modules (the static ones) programatically in windows

  - by Ryan Rohrer

  I'm trying to port the unix utility ldd to windows, because dependency walker and cygcheck don't quite give me the usage I'm looking for. (also for the learning experience) Ive been looking all over MSDN, for a windows API that lists dll dependencies of an executable, or even the storage format in the complied exe (just to filter it out), but I've been unable to find anything. If anyone knows what API call windows uses for listing modules to load, or what patterns I can search for in an executable to find modules to load, please help me out :) thanks! -note: I'm not looking to profile for dynamic modules, just list the ones that are required at runtime

• Delphi: How to assign dynamically an event handler without overwriting the existing event handler?

  - by user193655

  I need to loop through Components and assign an event handler (for example Dynamically assigning OnClick event for all TButton to ShowMessage('You clicked on ' + (Sender as TButton).Name); The problem is that in some cases I alreasy assigned the TButton OnClick event. Is there a way to solve the problem? Let's imagine I have Button1 for which the harcoded onclick event handler is: ShowMessage('This is Button1'); After my "parsing" I would like that the full event handler for Button1 becomes: ShowMessage('This is Button1'); // design time event handler code ShowMessage('You clicked on ' + (Sender as TButton).Name); // runtime added Note: I am looking for a soliution that allows me to use TButton as it is without inheriting from it.

My code works for direct path (something like 'path/to/directory') but not for dynamic path taken from runtime. $directory_self = dirname($_SERVER['PHP_SELF']); $folder = $_POST['folder_name']; //final folder $toupload = $_SERVER['DOCUMENT_ROOT'] . $directory_self .'/files'. $folder; $uploadsDirectory = str_replace (" ", "", $toupload); When i echo $uploadsDirectory it shows the exact path. Could any one help me what could be wrong in this?

• API for configuring static IP addresses in an android application

  - by awoodland

  Is it possible to set the IP address of an interface in Android within an application? I can query the available interfaces and their current addresses using java.net.NetworkInterface, but this doesn't provide a facility to change these. Did I just miss something somewhere or is it not allowed? I was hoping to be able to make my application either change or add an alias to one or more of the existing interfaces at runtime on an "off the shelf" device. (2.1/2.2). Ideally I'd like to do this for both IPv4 and v6 addresses.

• Are conditional subqueries optimized out, if the condition is false?

  - by Tobias Schulte

  I have a table foo and a table bar, where each foo might have a bar (and a bar might belong to multiple foos). Now I need to select all foos with a bar. My sql looks like this SELECT * FROM foo f WHERE [...] AND ($param IS NULL OR (SELECT ((COUNT(*))>0) FROM bar b WHERE f.bar = b.id)) with $param being replaced at runtime. The question is: Will the subquery be executed even if param is null, or will the dbms optimize the subquery out? We are using mysql, mssql and oracle. Is there a difference between these regarding the above?

• Converting table based layout into a div/css based one.

  - by nimo9367

  I'm supposed to rewrite the UI for a rather large web application. The thing is that the layout is completely based on tables and if I could somehow, semi automatically, convert the tables into divs it would save me a huge amount of time. What are the best practices when doing something like this? Is this a good idea at all? The application use layout files (containing something similar to helpers) that are parsed into html at runtime and the application itself also output html at specific places. So the work will consist of converting these helpers and the htmloutput code within the application.

• Locale C++ shared library in /usr/local/lib

  - by Dave

  I'm venturing into the world of C++ and Linux, and am having problems linking against a shared library. I have a library, libicuuc.so.44.1, installed in /usr/local/lib. There is also a link in the same directory, libicuuc.so.44 pointing to that library. My /etc/ld.so.conf reads: include /etc/ld.so.conf.d/*.conf I have a file, /etc/ld.so.conf.d/libc.conf, that contains: # libc default configuration /usr/local/lib However, when I compile my program (that includes LIBS += -licuuc), I get the following error at runtime: error while loading shared libraries: libicuuc.so.44: cannot open shared object file: No such file or directory I am using Qt Creator on Ubuntu 10.04. Any help is greatly appreciated!

• The best practice to setup hierarchy data

  - by eski

  I'm trying to figure out the best practice to setup hierarchy data that i take from a database into some contoller that would show the hierachy. Basicly this would look like a normal tree but when you press the items that are under "chapters" you get a link to another page. I have these tables and this is the way they are connected Period Courses Subjects Chapters I select Period from a DropDownBox and then i want all the courses in that period to line up. Under each course would be the subject and under them are the chapers, typical hierarchy. The tables are linked together with refrences to each other in linear way. I have tried to use treeview to show this, but dont understand how to do it. I though i could use <ul><il> tags and do it at runtime. Reapeter or datalist, possible ? Is it better to do this with databinding in XAML or in code ?

• How do I run Eclipse using Oracle's new 1.7 JDK for the Mac?

  - by sanity

  I'm trying to get the new 1.7 JDK working with Eclipse (this is Oracle's official release). I don't mean just pointing Eclipse to it so you can use it in projects, this works fine, but actually making Eclipse run using the 1.7 JVM. I've moved the new JVM to the top of the list in Java Preferences, but Eclipse still starts with 1.6. If I disable 1.6 in Java Preferences I get a dialog immediately after I double-click on Eclipse saying "Failed to create the Java Virtual Machine". edit: I added the following to my eclipse.ini just before the -vmargs: -vm /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home/bin/java Yet in the Eclipse installation details dialog I still see: java.runtime.version=1.6.0_31-b04-415-11M3646 edit 2: here are the contents of my eclipse.ini file: https://gist.github.com/2512578

• Is there any way to prevent a Delphi application from using Virtual Storage on Vista/Win 7 without e

  - by croceldon

  The question pretty much says it all. I have an app with an older component that doesn't work right if runtime themes are enabled. But if I don't enable them, the app always ends up messing with the virtual store. Thanks! Update: Using Mark's solution below, the application no longer writes to the Virtual Store. But, now it won't access a tdb file (Tiny Database file) that it needs. This tdb file is the same file that was being written to the Virtual store. Any ideas on how I can give it access to the tdb file and still prevent writing the Virtual Store?

• Ajax image upload and javascript edit on the fly with ASP.NET MVC (without saving to disk)

  - by gavss

  1) Uploadimage action gets requests from form posts. <form action="/content/uploadimage" method="post" enctype="multipart/form-data"> It reads HttpPostedFileBase stream data and sends it to the response. I need to show the image in a div container instead of sending it to the response as a file so that users can manipulate the image using jcrop. Image source is generated at runtime. I can't pass an action name to the src attribute. Is this possible using MVC and without using control viewstate? 2) I don't want to use flash or silverlight. Is there an easy ajax alternative to the method I use to get files from user?

• R looking for the wrong java version

  - by Veit

  Hi, I installed/uninstalled java jre/jdk now many times and finally installed the older version 1.6.0_17 which is now located at "C:\Program Files\Java\jre6\bin". Now after all if I call 'java -version' within R i can see that R is looking for Java at the old path which is now wrong. The question is: Why is R looking for Java at the wrong path even so the windows path is set correctly? There are no double entrys within the windows path as far as I can see and I restarted R as well as Windows more then once since then. Any Ideas where R takes the wrong path from? On windows shell: $set [..] OS=Windows_NT Path=C:\Program Files\Java\jre6\bin; [..] $ java -version java version "1.6.0_17" Java(TM) SE Runtime Environment (build 1.6.0_17-b04) Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01, mixed mode) within R: $system("java -version") Error: could not open `C:\Program Files (x86)\Java\jre6\lib\i386\jvm.cfg'

• ASP.Net website makes browser load unwanted (non-referenced) plugins

  - by alec0001

  I've found that some of my ASP.Net web apps prompt the browser to load plugins that I'm not explicitely using and certainly haven't deliberately referenced in the project settings. Two that come to mind are for MS MediaPlayer and the "SVG Viewer for Netscape". The only commonality I've determined so far is that the two sites/apps affected both use Master pages (nested in some cases). We don't use SVG file types (just the normal mix of jpg/gif/png) and no video/audio (not yet anyway). Can anyone provide a hint as to where the references for these might be creeping in? e.g. Is it a server-level include? Or a .Net runtime default when using master pages? Does anyone else even experience this, or is it just me? No urgency, I'd just like to remove it if possible. Thanks. Al

• Sharing memory between modules

  - by John Holecek

  Hi, I was wondering how to share some memory between different program modules - lets say, I have a main application (exe), and then some module (dll). They both link to the same static library. This static library will have some manager, that provides various services. What I would like to achieve, is to have this manager shared between all application modules, and to do this transparently during the library initialization. Between processes I could use shared memory, but I want this to be shared in the current process only. Could you think of some cross-platform way to do this? Possibly using boost libraries, if they provide some facilities to do this. Only solution I can think of right now, is to use shared library of the respective OS, that all other modules will link to at runtime, and have the manager saved there.
