• UITableViewController truncating section header title

  - by dl

  I've got an iPad app with a UITableViewController. I am setting the header titles for my table sections using - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section When the table loads, if I scroll down too quickly, when a section header appears on screen it will be truncated to the first letter and ... (ie "Holidays" is trucated to "H..."). If I keep scrolling down until the header goes off the top of the view and then scroll back up to it, the title appears correctly in full. Has anyone ever experienced this?

• .NET 2.0: Invoking Methods Using Reflection And Generics Causes Exception

  - by David Derringer

  Hi all, I'm new to Stack Overflow, so forgive me. I've just started transititoning over to C# and I am stuck on a problem. I am wanting to pass a generic class in and call a method from that class. So, my code looks as such: public void UpdateRecords<T>(T sender) where T : new() //where T: new() came from Resharper { Type foo = Type.GetType(sender.GetType().ToString()); object[] userParameters = new object[2]; userParameters[0] = x; userParameters[1] = y; sender = new T(); //This was to see if I could solve my exception problem MethodInfo populateRecord = foo.GetMethod("MethodInOtherClass"); populateMethod.Invoke(sender, userParameters); } Exception thrown: "Object reference not set to an instance of an object." Again, I really apologize, as I am nearly brand new to C# and this is the first time I've ever handled reflection and generics. Thank you!

• Reallocating memory via "new" in C++

  - by BSchlinker

  Quick question regarding memory management in C++ If I do the following operation: pointer = new char [strlen(someinput_input)+1]; And then perform it again, with perhaps a different result being returned from strlen(someinput_input). Does this result in memory being left allocated from the previous "new" statement? IE, is each new statement receiving another block of HEAP memory from the OS, or is it simply reallocating? Assuming I do a final delete pointer[]; will that deallocate any and all memory that I ever allocated via new to that pointer? Thanks

• What is the benefits and drawbacks of using header files?

  - by vodkhang

  I had some experience on programming languages like Java, C#, Scala as well as some lower level programming language like C, C++, Objective - C. My observation is that low level languages separate out header files and implementation files while other higher level programming language never separate it out. They use some identifiers like public, private, protected to do the jobs of header files. I saw one benefit of using header file (in some book like Code Complete), they talk about that using header files, people can never look at our implementation file and it helps with encapsulation. A drawback is that it creates too many files for me. Sometimes, it looks like verbose. It is just my thought and I don't know if there are any other benefits and drawbacks that people ever see and work with header file This question may not relate directly to programming but I think that if I can understand better about programming to interface, design software.

• problem with HttpWebRequest.GetResponse perfomance in multithread applcation

  - by Nikita

  I have very bad perfomance of HttpWebRequest.GetResponse method when it is called from different thread for different URLs. For example if we have one thread and execute url1 it requires 3sec. If we ececute url1 and url2 in parallet it requires 10sec, first request ended after 8sec and second after 10sec. If we exutet 10 URLs url1, url2, ... url0 it requires 1min 4 sec!!! first request ended after 50 secs! I use GetResponse method. I tried te set DefaultConnectionLimit but it doesn't help. If use BeginGetRequest/EndGetResponse methods it works very fast but only if this methods called from one thread. If from different it is also very slowly. I need to execute Http requests from many threads at one time. ?an anyone ever encountered such a problem? Thank you for any suggestions.

• A submenu (`ToolStripMenuItem`) does not show automatically.

  - by czuk

  I have encountered strange problem with a three-level context menu. In some situation the sub menu does not show automatically. I have following structure of the menu: * AAA - level 1 * BBB - level 1 * CCC - level 2 * xxx - level 3 * yyy - level 3 * DDD - level 2 * zzz - level 3 * vvv - level 3 I start from a menu with two option AAA and BBB. After I move the cursor over BBB the second-level menu appears with two other options CCC and DDD. So far OK. Now, when I quickly move the cursor over DDD the third-level sub menu does not show up, but when I move the cursor back to CCC the sub menu shows up, and when I go back to DDD then the sub menu also shows. Why it does not show at first time? Have you ever encountered such a problem? I fixed the problem with MouseEnter and MouseLeave events, but I still wonder why it does not work properly without the events.

• Making Django ignore string literals

  - by James

  UPDATE: It turns out this is a deeper question than I thought at first glance - the issue is that python is replacing the string literals before they ever get to django. I will do more investigating and update this if I find a solution. I'm using django to work with LaTeX templates for report generation, and am running into a lot of problems with the way Django replaces parts of strings. Specficially, I've run into two problems where I try to insert a variable containing latex code. The first was that it would replace HTML characters, such as the less than symbol, with their HTML codes, which are of course gibberish to a LaTeX interpreter. I fixed this by setting the context to never autoescape, like so: c = Context(inputs) c.autoescape = False However, I still have my second issue, which is that Django replaces string literals with their corresponding characers, so a double backslash becomes \, and \b becomes a backspace. How can I force Django to leave these characters in place, so inputs['variable'] = '{\bf this is code} \\' won't get mangled when I use {{variable}} to reference it in the django template?

• Finding files with bash and copy to another location and reducing depth of folders

  - by Kevin F

  I'm trying to recover a mates hard drive, there is no structure what so ever so music and images are everywhere but in named folders sometimes 5 folders deep, I've managed to write a one-liner that finds the files and copies them to a mounted drive but it preserves the file structure completely. What I'm after is a bit of code that searches the drive and copies to another location and copies just the parent folder with the mp3/jpg files within and not the complete path. The other issue I have is the music is /folder/folder/folder/Artist/1.mp3..2.mp3..10.mp3 etc etc so I have to preserve the folder 'Artist' to give him any hope of finding his tracks again. What I have working currently: find /media/HP/ -name *.mp3 -fprintf /media/HP/MUSIC/Script.sh 'mkdir -p "/media/HP/MUSIC/%h" \n cp "%h/%f" "/media/HP/MUSIC/%h/"\n' I then run the script.sh and it does all the copying. Many Thanks

• Rails fixtures seem to be adding extra unexpected data

  - by Mason Jones

  Hello, all. I've got a dynamic fixture CSV file that's generating predictable data for a table in order for my unit tests to do their thing. It's working as expected and filling the table with the data, but when I check the table after the tests run, I'm seeing a number of additional rows of "blank" data (all zeros, etc). Those aren't being created by the fixture, and the unit tests are read-only, just doing selects, so I can't blame the code. There doesn't seem to be any logging done during the fixtures setup, so I can't see when the "blank" data is being inserted. Anyone ever run across this before, or have any ideas of how to log or otherwise see what the fixture setup is doing in order to trace down the source of the blank data?

• C++ Header Guard issues

  - by JP

  I am making a small C++ framework, which contains many .h and .cpp. I have created a general include which include all my .h file such as: framework.h #include "A.h" #include "B.h" #include "C.h" each .h header are protected with include guard such as #ifndef A_HEADER #define A_HEADER ... #endif The issues is, I would like to be able to include "framework.h" inside all the sub .h such as, but it cause lots of compiler error: #ifndef A_HEADER #define A_HEADER #include "framework.h" ... #endif If instead I use the real header file for each sub header, and the framework.h for what ever use my framework it works fine.. I would just like to include the main header inside all my sub .h so I dont need to include all the dependency everytime. Thanks :)

• Loss of precision - int -> float or double

  - by stan

  I have an exam question i am revising for and the question is for 4 marks "In java we can assign a int to a double or a float". Will this ever loose infromation and why? I have put that because ints are normally of fixed length or size - the precision for sotring data is finite, where storing information in floating point can be infinite, essentially we loose infromation because of this Now i am a little sketchy as to whetehr or not i am hitting the right areas here. I very sure it will loose precision but i cant exactly put my finger on why. Can i getsome help please Thanks

• How can I make CAPTCHA work across multiple pages?

  - by jm04469

  Ever visit a website such as myspace where they leverage CAPTCHA to prevent spam? The typical pattern is to present a challenge to each URL that is opened, yet the challenge doesn't actually belong to the page itself which causes additional bandwidth usage. So, if I open up six pages at the same time and want to present a challenge on each page. I want the challenge to be tied to the page and not to the session. How can I make this work with Spring and/or Struts.

• Does normalization really hurt performance in high traffic sites?

  - by Luke101

  I am designing a database and I would like to normalize the database. I one query I will joining about 30-40 tables. Will this hurt the website performance if it ever becomes extremely popular? This will be the main query and it will be getting called 50% of the time. The other queries I will be joining about 2 tables. I have a choice right now to normalize or not to normalize but if the normalization becomes a problem in the future i may have to rewrite 40% of the software and it may take me a long time. Does normalization really hurt in this case? Should I denormalize now while I have the time?

• Make multiple lightboxes (facebox) execute one after each other.

  - by Jigs

  I have a php application that sometimes creates two lightboxes on the same page - the result is the last one to be called is the only one shown. How might I ensure that they show one after anohter? I call a facebox at the bottom of the page like so: jQuery.facebox('blah'); Currently multiple facebox's are called like so: jQuery.facebox('blah');jQuery.facebox('blah2'); But only blah2 will ever show. I need to wait for 'blah' to close before calling 'blah2'...

• Why doesn't MySQL support millisecond / microsecond precision?

  - by Byron Whitlock

  So I just found the most frustrating bug ever in MySQL. Apparently the TIMESTAMP field, and supporting functions do not support any greater precision than seconds!? So I am using PHP and Doctrine, and I really need those microseconds (I am using the actAs: [Timestampable] property). I found a that I can use a BIGINT field to store the values. But will doctrine add the milliseconds? I think it just assigns NOW() to the field. I am also worried the date manipulation functions (in SQL) sprinkled through the code will break. I also saw something about compiling a UDF extension. This is not an acceptable because I or a future maintainer will upgrade and poof, change gone. Has anyone found a suitable workaround?

• Why can't I access Jetty running on my Mac via my iPhone?

  - by bpapa

  I'm developing an iPhone app that has a network component. I'm developing the app in Java (Google App Engine actually), running on port 8080. And it works, when I test my app in the iPhone simulator. But now I am trying to test on the device, and I can't hit my Jetty instance. I can certainly access my Mac via the iPhone because I'm able to hit http://10.0.1.7/~brianpapa/ and view my Home Folder when Web Sharing is turned on. But when I try to hit http://10.0.1.7:8080/, it says it can't connect to the server. Interestingly, if I try to hit http://10.0.1.7:8080/ from my mac, it doesn't work either - I have to use localhost as the hostname instead, then it's fine. Has anybody ever encountered this before, and know how to fix it?

• How to use Eclipse's Display View for Debug?

  - by jzd

  At the link below it explains that the "display view allows you to manipulate live code in a scrapbook type fashion (see Figure 8). To manipulate a variable, simply type the name of the variable in the Display view, and you'll be greeted with a familiar content assist." http://www.ibm.com/developerworks/library/os-ecbug/ However, I am having trouble getting it to work. I have the view open but all the buttons are disabled. I have tried putting code in the view, selecting code in the view, selecting code in other views, while running and while not running debug, but the only button that is ever enabled on the view is "clear console". Suggestions on what I am doing wrong?

• Image Upload directly from client to remote server? Spring/Tomcat

  - by Prem

  Just wondering what the common solution is for this. We have two web servers that are load balanced and a separate server that holds our images. Our current process is that a user uploads an image directly to the web server (which ever they are connected to) and we enter a job into our DB. Another process checks for image jobs every few mins and copies the image from the web server up to the image server. The delay from when a user uploads to when its visible is not ideal. We could tighten the loop on how often we check for image jobs but ideally I would like to have user uploaded images to go directly to the image server rather than copying twice. How should this be done? Is there anything in spring to deal with this ? Seems like how most would deal with a CDN i would think? I want to limit the time it takes for an image that a user uploads is available on our site...

• Securing a REST API

  - by Christopher McCann

  I am in the middle of developing a REST API - the first one I ever have. The data being passed through the API is not of such a critical nature that there will be loss of life, economics etc if it was intercepted but at the same time I would like it to be secure. The data being transferred is simply like the data that would be transferred on Twitter or Facebook - not overly confidential but still should be kept private. What is the best way to secure this data? Am I best to use HTTP Basic Auth over SSL or should I be looking into something like OAuth. I have never really used REST much before so bit of a first for me. Thanks

• Determining Terminal lines/cols via PHP CLI

  - by eFrane

  I know that it is quite easy to figure out a terminal's size parameters via the stty -a command. When using local CLI PHP scripts, there is no problem at all on grabbing that output via system() or so. But I am trying the same thing via a php script started from an ssh command. Sadly, all that stty ever returns is: stty: standard input: Invalid argument. The calling code is: exec('stty -a | head -n 1', $query); echo $query[0]; So the question is: If I can output to the terminal and read input from it (e.g. can fread() from STDIN and fwrite() to STDOUT in PHP, shouldn't stty also have valid STDIN and STDOUT?

• Autofiltered List; cross-row formula

  - by Chris Gunner

  I have a large Autofiltered list (~600 rows), with some of the rows being summary rows that I want to use a UDF to display the lowest priority listed in any of the 'child' cells. I can pass to my formula the right cells, but they are no longer correct if the list is re-ordered in any way. Is there a way to give the formula the right cell and have it recognise that I want that row and only ever that row? I can do it with a VLOOKUP to look at a hidden column that lists wether the 'child' row matches the right criteria, but with 600 rows and each parent row requiring about a dozen 'child' cells each, it's too slow.

• Create a javascript chome extention that does not execute in 6 months

  - by user1907657

  I have just started learning programming and I would like to make a script into a chrome extension. Its a basic script and I hope to practice more and more and develop bigger projects and set myself bigger tasks This script has to do the following : reload a page every 20 seconds (say google.com) after 6 months the script must not run (maybe prompt a window saying "its over 6 months") The code should be able to go into a small chrome extension and also the 6 month time period should be absolute not relative to the time the script was started; for example should the browser crash and i have to turn on the extension again it should not restart the 6 month counter. Also if anyone could recommend any good sources for JavaScript to learn (preferably books; nothingIi read online ever seems to stick)

• TeamCity build triggers don't automatically run

  - by Phil.Wheeler

  I've been playing around with and learning a bit about TeamCity and have the server correctly set up with my .Net MVC project committed in Subversion successfully and build configurations and triggers sorted to kick off when any changes are committed to the repository. TeamCity polls on its default time period and is picking up that changes have been committed, but it is adding these to the queue without actually ever running them. I have to manually click the "Run" button to kick them off. What setting do I need to change in order to ensure that any new changes are automatically run?
