• Problem when exiting search in iPhone

  - by camilo

  Hi. I have a search display controller, and it is searching well. I'm searching in a table with several sections and I have a viewForHeaderInSection function working as it's supposed to. When I start searching, my numberOfSectionsForTableView returns 1, and I have a special view saying "Search Results" wich I use in self.searchDisplayController.searchResultsTableView. The problem happens when I select a row in my searchResultsTableView: I change the view, and when I return and try to exit the searchDisplayController (by pressing the CancelButton), the tables change nice, but changing the viewforHeader for my first section is not "pretty". I have a "kind-of-click" anymation. I would like it to not be so noticeable for the user, having a more "fluid" change. Anybody had the same problem and knows how to solve it? In a different question (which would work as a workaround): how can I hide the keyboard while searching without pressing the Cancel or Search buttons? Thanks a lot!

• Using "Go To Controller" and "Go To View" in Visual Studio 2008 when controllers are in different as

  - by ElvisLives

  The title is basically the question. We decided to move our controller classes to a separate library and reference it in our asp.net mvc 2 application. It works just fine when running the application, meaning the controllers are being referenced while the application is running. But when doing development (in Visual Studio 2008) and I am in a View and try to use the context menu "Go To Controller" it can't find our controllers in the new assembly. Same with when I am inside a controller, I don't have the Context menu to "Add View" or "Go To View" anymore. Does anyone one know how to remedy this? I searched like crazy but haven't found any solutions or even half solutions. Thanks!

• Resizing Ubuntu x64 Server Partition with VirtualBox not reflected in OS

  - by daleyjem

  I've already resized my virtual disk with VirtualBox, but now need to extend the partition of my Ubuntu VM itself. I thought I was on my way with GParted live CD, but after I resize the "extended" filesystem partition, and then the child "lvm2 pv" filesystem partition to fill the unallocated space, df -h still shows the original disk size after I reboot into the VM. Any tips on this? I've scoured the webs tirelessly. Should I be resizing the boot (/dev/sda1) partition instead? Should I try to convert my lvm2 to ext4 or something? I'm lost on this. Note: VirtualBox hard disk is "dynamic". Specs: VBox 4.2.18 Ubuntu 12.04.2 amd64 Gparted 0.16.2-1b-i486

• Is it bad practice to initialize a variable to a dummy value?

  - by froadie

  This question is a result of the answers to this question that I just asked. It was claimed that this code is "ugly" because it initializes a variable to a value that will never be read: String tempName = null; try{ tempName = buildFileName(); } catch(Exception e){ ... System.exit(1); } FILE_NAME = tempName; Is this indeed bad practice? Should one avoid initializing variables to dummy values that will never actually be used? (EDIT - And what about initializing a String variable to "" before a loop that will concatenate values to the String...? Or is this in a separate category? e.g. String whatever = ""; for(String str : someCollection){ whatever += str; } )

• How to split the chance to display SWFs evenly among banner collection?

  - by Michael Mao

  Hi all: I am working on The ausdcf.org to try adding several banner ads in swf format to the top. Everything starts to work, but I've got several questions that need your help: The client chose not to go with Google AdManager, but prefer a "minimal approach" to do this task. What I am trying to do is sort of "mimicking" the way Google AdManager does for banners, that is, to split the chance of each particular swf to be shown to the visitor evenly among the banner collection. Definitely I can add some jQuery code to do this from client-side, a random number generator and if-else statement would work - just $.load() it! However, what if I'd like to make sure those disabled Javascript (is there any now btw?) still be able to see different swfs in each visit. Any suggestion on how to approach this? Many thanks in advance.

• How to read output of android process command

  - by kevdliu

  I am trying to get the output of android shell command 'getprop' with java since getprop() always returns null no matter what. I tried this from developer.android.com: Process process = null; try { process = new ProcessBuilder() .command("/system/bin/getprop", "build.version") .redirectErrorStream(true) .start(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } InputStream in = process.getInputStream(); //String prop = in.toString(); System.out.println(in); process.destroy(); However what is printed is not the output but a bunch of characters and numbers (dont have the exact output right now). How can i get the output of the process? Thanks!

Any ideas whats happening here?

• Methods specific only to an instance? What are they called in Ruby?

  - by daremarkovic

  I know there are "instance methods", "class methods" but what are these types of methods called, for eg: s1 = "This is my STRING!" def s1.m1 downcase end p s1 # => "This is my STRING!" p s1.m1 # => "this is my string!" What type of method is the "m1" method called on the s1 "instance" of the "string" class? It's really weird because I didn't know this was possible at all if I try: s2 = "This is ANOTHER string" s2.m1 # => Won't work! Which kind of makes sense, but not sure why defining methods like m1 on instances on a class are useful at all.

• How does the increment operator (++) work on DateTime in C#

  - by sohtimsso1970

  What happens if you use the increment operator (++) on a DateTime type in C#? For instance, if I did this: DateTime blah = new DateTime(2010, 12, 24); blah++; What does blah become? Does that increment by a tick or a day? Or is that even legal? I don't have a dev environment around, and won't for a few days, or I would just try it and find out. I was too curious to wait so I figured I'd ask the community.

• Index out of range exception when using this query from C#

• Is PThread a good choice for multi-platorm C/C++ multi-threading program?

  - by RogerV

  Been doing mostly Java and smattering of .NET for last five years and haven't written any significant C or C++ during that time. So have been away from that scene for a while. If I want to write a C or C++ program today that does some multi-threading and is source code portable across Windows, Mac OS X, and Linux/Unix - is PThread a good choice? The C or C++ code won't be doing any GUI, so won't need to worry with any of that. For the Windows platform, I don't want to bring a lot of Unix baggage, though, in terms of unix emulation runtime libraries. Would prefer a PThread API for Windows that is a thin-as-possible wrapper over existing Windows threading APIs. ADDENDUM EDIT: Am leaning toward going with boost:thread - I also want to be able to use C++ try/catch exception handling too. And even though my program will be rather minimal and not particularly OOPish, I like to encapsulate using class and namespace - as opposed to C disembodied functions.

• Creating a JSONRepresentation of my NSDictionary messes up the order?

  - by Lewion

  Hi all, To pass data to my webservice, I create an NSDictionary with the objects and keys I need, and use JSONRepresentation to format it nicely so I can post it to my service. It all worked fine with the previous version where only 2 parameters were required. An array with listitems, and a UDID. No I also need to pass a version number because we need to provide more data for people with the application at this new version. Only problem is when I create my JSONRepresentation now, the order of things are all messed up. NSMutableDictionary *rowDict = [[NSMutableDictionary alloc] initWithObjectsAndKeys:arrayDict,@"basketListV2",sharedData.udid,@"UDID",@"1.4",@"version",nil]; It prints out version first, then UDID and then basketListV2. Anyone know what I can do to maintain the order of my NSDict? I tried both NSDictionary and NSMutableDictionary (Probably doesn't have to do anything with it but for testing purposes I had to try it.) Thanks in advance. Lewion

• Error occurs while using SPADE method in R

  - by Yuwon Lee

  I'm currently mining sequence patterns using SPADE algorithm in R. SPADE is included in "arulesSequence" package of R. I'm running R on my CentOS 6.3 64bit. For an exercise, I've tried an example presented in http://en.wikibooks.org/wiki/Data_Mining_Algorithms_In_R/Sequence_Mining/SPADE When I tried to do "cspade(x, parameter = list(support = 0.4), control = list(verbose = TRUE))" R says: parameter specification: support : 0.4 maxsize : 10 maxlen : 10 algorithmic control: bfstype : FALSE verbose : TRUE summary : FALSE preprocessing ... 1 partition(s), 0 MB [0.096s] mining transactions ... 0 MB [0.066s] reading sequences ...Error in asMethod(object) : 's' is not an integer vector When I try to run SPADE on my Window 7 32bit, it runs well without any error. Does anybody know why such errors occur?

• Notepad++ regular expression find and replace $_REQUEST with $_GET but a more secure

  - by David

  What I am doing is replacing, in a large program, all $_REQUEST['var'] and mysql_escape_string($_REQUEST['var']) with either the 1st or 2nd line below the dotted line. Now, I have figured out this much of the regular expression but I would like to make it simpler. Instead of having to run the top one first then the 2nd one I would like to just run one all together. I tried this but it did not work. (mysql_escape_string\()*$_REQUEST\[\'([^']*)\'\]\)(\)*) So below is what works but again have to do it twice. $_REQUEST\[\'([^']*)\'\] mysql_escape_string\($_REQUEST\[\'([^']*)\'\]\) (isset($_GET['\1'])?mysql_real_escape_string($_GET['\1']):false) (isset($_POST['\1'])?mysql_real_escape_string($_POST['\1']):false) ============================ Update: Yeah, after some research I figured out that Notepad++ does not support most regular expressions. I guess one additional step can not hurt a person. It's just laziness. *NOTE: BUT if anyone wants to try feel free to comment. At least it is just 2 steps and not 20.

• Capture subprocess output

  - by schneck

  Hi there, I learned that when executing commands in Python, I should use subprocess. What I'm trying to achieve is to encode a file via ffmpeg and observe the program output until the file is done. Ffmpeg logs the progress to stderr. If I try something like this: child = subprocess.Popen(command, shell=True, stderr=subprocess.PIPE) complete = False while not complete: stderr = child.communicate() # Get progress print "Progress here later" if child.poll() is not None: complete = True time.sleep(2) the programm does not continue after calling child.communicate() and waits for the command to complete. Is there any other way to follow the output?

• Mysterious c debugging problem when trying to utilize printfs

  - by O_O

  Ok, folks. I've never encountered this before and it boggles the mind and is illogical. I have a somewhat complex loop and I want to try and see if everything is working by putting some printf statements. I look the intermediate products using printf and verify that the answer is ok. Then, when I comment out the printf to the intermediate products, the answer is WRONG. Has anyone ever encountered this? This is driving me insane and I don't see how the printfs could change an answer.... X_x If it helps, I am using a c/c++ compiler for a DSP. Thanks for any advice.. Here is a snippet... printf("splitBackground = %d, numWindowPoints = %d\n", splitBackground, numWindowPoints); splitBackground = splitBackground/numWindowPoints; printf("%d ", splitBackground); This is good but when I comment out the first line of code, it turns out to be hugely incorrect. :(

• Tomcat + Struts + OpenID raising ServletExceptions

  - by Rocjoe

  I am working with Tomcat 5.5.x with Struts 1.2 to run a rather large website (large w.r.t. source code). I'm looking to add OpenID to my website, mostly to access attribute exchange to help accelerate the registration process. Every Java implementation for OpenID I have attempted to use will cause a ServletException. Tracing this has been very difficult, but it seems merely instancing any class that makes use of Apache HttpClient will cause the crash. Is this a configuration problem I can address in the JVM, or is it positively wrong to try to initiate an outbound Http request from within an inbound Http request?

• What is your favorite colorscheme FOR PROGRAMMING in Vim?

  - by ThomasGHenry

  I think this is a relevant question for programmers and I'd like to hear other people's answers because some syntax highlighting color schemes are better on the eyes than others. This can affect productivity as much as ergonomic keyboards or anything else on here. It's about comfort and productivity. So, I'm curious. Do you find some color schemes better adapted for some languages over others? At the other end of the spectrum, I think coding without syntax highlight is awful and slow going. Does anyone work better like this? Thanks! EDIT: so we'll try it as a community wiki. Similar Question
