  • for question about autorotation

    - by user177893
    my superview is UItabelview and my subviews are UITabelview and UIDatePicker. for my subviews didn't able to call (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration why? bcoz this method calls when view rotates and at that time i want to set autoresizingmask method for that view so that when my subview rotates from Portrait to landscape mode it's view resizes automatically?

  • g++ Linking Error on Mac while compiling FFMPEG

    - by Saptarshi Biswas
    g++ on Snow Leopard is throwing linking errors on the following piece of code test.cpp #include <iostream> using namespace std; #include <libavcodec/avcodec.h> // required headers #include <libavformat/avformat.h> int main(int argc, char**argv) { av_register_all(); // offending library call return 0; } When I try to compile this using the following command g++ test.cpp -I/usr/local/include -L/usr/local/lib \ -lavcodec -lavformat -lavutil -lz -lm -o test I get the error Undefined symbols: "av_register_all()", referenced from: _main in ccUD1ueX.o ld: symbol(s) not found collect2: ld returned 1 exit status Interestingly, if I have an equivalent c code, test.c #include <stdio.h> #include <libavcodec/avcodec.h> #include <libavformat/avformat.h> int main(int argc, char**argv) { av_register_all(); return 0; } gcc compiles it just fine gcc test.c -I/usr/local/include -L/usr/local/lib \ -lavcodec -lavformat -lavutil -lz -lm -o test I am using Mac OS X 10.6.5 $ g++ --version i686-apple-darwin10-g++-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664) $ gcc --version i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5664) FFMPEG's libavcodec, libavformat etc. are C libraries and I have built them on my machine like thus: ./configure --enable-gpl --enable-pthreads --enable-shared \ --disable-doc --enable-libx264 make && sudo make install As one would expect, libavformat indeed contains the symbol av_register_all $ nm /usr/local/lib/libavformat.a | grep av_register_all 0000000000000000 T _av_register_all 00000000000089b0 S _av_register_all.eh I am inclined to believe g++ and gcc have different views of the libraries on my machine. g++ is not able to pick up the right libraries. Any clue?

  • mvn deploy to AWS (ssh via distributionManagement)

    - by Dexter
    I am working on deploying the WAR file to AWS using Maven. I am planning to use 'mvn deploy' for the same which would ssh the war file to AWS.

  • Advantages/disadvantages of browser-based interface vs. graphics

    - by Josh
    Hello everyone, I'm in the design phase for a desktop-based application. Because of the nature of this particular application, I believe it would benefit greatly from a web-based approach (i.e., allowing a user to interface with the application through a browser running in kiosk mode) in order to leverage the simplicity of HTML/CSS/JS and the availability of many great JS interface plugins. Does taking this approach (rather than coding in a native or cross-platform graphics library) come with any gotchas?

  • java 6 web services share domain specific classes between server and client

    - by user173446
    Hi all, Context: Considering below defined Engine class being parameter of some webservice method. As we have both server and client in java we may have some benefits (???) in sharing Engine class between server and client ( i.e we may put in a common jar file to be added to both client and server classpath ) Some benefits would be : we keep specific operations like 'brushEngine' in same place build is faster as we do not need in our case to generate java code for client classes but to use them from the server build) if we later change server implementation for 'brushEngine' this is reflected automatically in client . Questions: How to share below detailed Engine class using java 6 tools ( i.e wsimport , wsgen etc )? Is there other tools for java that can achieve this sharing ? Is sharing a case that java 6 web services support is missing ? Can this case be reduced to other web service usage patterns? Thanks. Code: public class Engine { private String engineData; public String getData(){ return data; } public setData(String value){ this.data = value; } public void brushEngine(){ engineData = "BrushedEngine"+engineData; } }

    I have a Asp.net web application running with the following config setting. <xhtmlConformance mode="Legacy"/> This limits use of AJAX and compatibility with multiple browser. If my understanding is correct, the HTML code of the aspx pages need to be fixed to comply with XHTML 1.0 Transitional. There are alot of HTML pages, ~1000, is there a tool that could speed up this process?

    Hi, it is possible to change global mouse cursor from c#? the thing is i use a global hook shortcut key to capture a window like spywindow and i want to change mouse cursor globally when i select my handle and restore it when i click left mouse. Another question is about the click itself. When I'm in capture mode can i take click just for my purpose?it will be nice if i didn't press stuff on screen when i select my window!. Thanks!

  • Performing full screen grab in windows

    - by Steven Lu
    I am working an idea that involves getting a full capture of the screen including windows and apps, analyzing it, and then drawing items back onto the screen, as an overlay. I want to learn image processing techniques and I could get lots of data to work with if I can directly access the Windows screen. I could use this to build automation tools the likes of which have never been seen before. More on that later. I have full screen capture working for the most part. HWND hwind = GetDesktopWindow(); HDC hdc = GetDC(hwind); int resx = GetSystemMetrics(SM_CXSCREEN); int resy = GetSystemMetrics(SM_CYSCREEN); int BitsPerPixel = GetDeviceCaps(hdc,BITSPIXEL); HDC hdc2 = CreateCompatibleDC(hdc); BITMAPINFO info; info.bmiHeader.biSize = sizeof(BITMAPINFOHEADER); info.bmiHeader.biWidth = resx; info.bmiHeader.biHeight = resy; info.bmiHeader.biPlanes = 1; info.bmiHeader.biBitCount = BitsPerPixel; info.bmiHeader.biCompression = BI_RGB; void *data; hbitmap = CreateDIBSection(hdc2,&info,DIB_RGB_COLORS,(void**)&data,0,0); SelectObject(hdc2,hbitmap); Once this is done, I can call this repeatedly: BitBlt(hdc2,0,0,resx,resy,hdc,0,0,SRCCOPY); The cleanup code (I have no idea if this is correct): DeleteObject(hbitmap); ReleaseDC(hwind,hdc); if (hdc2) { DeleteDC(hdc2); } Every time BitBlt is called it grabs the screen and saves it in memory I can access thru data. Performance is somewhat satisfactory. BitBlt executes in 50 milliseconds (sometimes as low as 33ms) at 1920x1200x32. What surprises me is that when I switch display mode to 16 bit, 1920x1200x16, either through my graphics settings beforehand, or by using ChangeDisplaySettings, I get a massively improved screen grab time between 1ms and 2ms, which cannot be explained by the factor of two reduction in bit-depth. Using CreateDIBSection (as above) offers a significant speed up when in 16-bit mode, compared to if I set up with CreateCompatibleBitmap (6-7ms/f). Does anybody know why dropping to 16bit causes such a speed increase? Is there any hope for me to grab 32bit at such speeds? if not for the color depth, but for not forcing a change of screen buffer modes and the awful flickering.

  • Loading a helper elsewhere than the autoload.php?

    - by drpcken
    I inherited a project and I'm cleaning up a bit and trying to finish it. I noticed that they used (or wrote) a breadcrumb helper. It is in my helpers folder and is named breadcrumb_helper.php It has a single function to build a breadcrumb menu with links and pass it to the view breadcrumbs.php. Here's the code: function show_breadcrumbs() { $ci =& get_instance(); $ci->load->helper('inflector'); $data = ''; //build breadcrumb and store in $data $this->load->view("breadcrumbs", $data) } I was trying to figure out how this helper worked and I checked the autoload.php but there is no reference to the helper in there. In face here is my autoload: $autoload['helper'] = array('url','asset','combine','navigation','form','portfolio','cookie','default'); This show_breadcrumbs() function is used quite a bit in some of my pages so I'm confused as to how its loading if it isn't in the autoloader. It is called like this in a few of my pages: <?=show_breadcrumbs()?> What am I missing? Why isn't this in my autoload? I even did a global search and couldn't find anywhere the helper is being loaded.

  • Where to store application global variable?

    - by Shawn Mclean
    I'm using silverlight, project structure is similiar to any other .net app. I have a map control that I would like to store what mode it is in (either road or aerial) so that other controls can access this. Where do I put this enum variable, I plan to use 2 way binding on it so both are updated when either changes. Thanks.

  • Need help with strange Class#getResource() issue

    - by Andreas_D
    I have some legacy code that reads a configuration file from an existing jar, like: URL url = SomeClass.class.getResource("/configuration.properties"); // some more code here using url variable InputStream in = url.openStream(); Obviously it worked before but when I execute this code, the URL is valid but I get an IOException on the third line, saying it can't find the file. The url is something like "file:jar:c:/path/to/jar/somejar.jar!configuration.properties" so it doesn't look like a classpath issue - java knows pretty well where the file can be found.. The above code is part of an ant task and it fails while the task is executed. Strange enough - I copied the code and the jar file into a separate class and it works as expected, the properties file is readable. At some point I changed the code of the ant task to URL url = SomeClass.class.getResource("/configuration.properties"); // some more code here using url variable InputStream in = SomeClass.class.getResourceAsStream("/configuration.properties"); and now it works - just until it crashes in another class where a similiar access pattern is implemented.. Why could it have worked before, why does it fail now? The only difference I see at the moment is, that the old build was done with java 1.4 while I'm trying it with Java 6 now. Workaround Today I installed Java 1.4.2_19 on the build server and made ant to use it. To my totally frustrating surprise: The problem is gone. It looks to me, that java 1.4.2 can handle URLs of this type while Java 1.6 can't (at least in my context/environment). I'm still hoping for an explanation although I'm facing the work to rewrite parts of the code to use Class#getRessourceAsStream which behaved much more stable...

  • Unknown and unreproducible crash causes App Store rejection

    - by Daniel Johnson
    After submitting our application several times, we continue to receive the following response: Thank you for submitting My App to the App Store. We've reviewed your application and determined that we cannot post this version of your iPad application to the App Store because My App is crashing on iPad running iPhone OS 3.2 and Mac OS X 10.6.2. My App crashes upon launch. Unfortunately, crash logs have not been generated. However, resigning the same build with the AdHoc entitlements and loading the build onto the device yields no such crash. After a number of attempts, the application simply does not crash as reported by the reviewer. Furthermore, the reviewer does not provide any useful logging that may have been generated by SpringBoard such as an exit status or event if it had worked properly for any other device. There are no calls to explicitly exit or quit the application in the code line and yet the application terminates on startup. What might cause an application to terminate in such a manner? Under what conditions is an application tested that might not be found under a development environment? Could it be a result of a signing issue that the submission validation system is simply unable to catch? Thanks in advance.

  • UNIX find for finding file names NOT ending in specific extensions?

    - by Cristi Diaconescu
    Is there a simple way to recursively find all files in a directory hierarchy, that do not end in a list of extensions? E.g. all files that are not *.dll or *.exe UNIX/GNU find, powerful as it is, doesn't seem to have an exclude mode (or I'm missing it), and I've always found it hard to use regular expressions to find things that don't match a particular expression. I'm in a Windows environment (using the GnuWin32 port of most GNU tools), so I'm equally open for Windows-only solutions.

  • C#: how to obtain the current clock speed of an Intel i-series CPU when TurboBoost is activated

    - by shifuimam
    I know that it's possible to get this information - Intel's own TurboBoost sidebar gadget appears to use an ActiveX control to determine the current clock speed of an i3/i5/i7 CPU when TurboBoost is active. However, I'm wanting to do this programmatically in C# - obtaining the CurrentClockSpeed value from WMI tops out at the set maximum clock speed of the CPU, so in TurboBoost mode, it doesn't report the current actual clock speed.

  • How to force emacs to use \n instead of \r\n

    I have to use windows to write some shell scripts. I decided to use emacs, but I get a weird error when running the script: /bin/bash^M: bad interpreter: No such file or directory Correct me if I'm wrong, but that looks like the shebang ends in \r\n instead of just \n. How can I tell emacs to only write \n? I'm in Shell-script major mode. It's quite surprising this isn't fixed by default.

  • Problems with rails and saving to the database.

    - by Grantismo
    I've been having some difficulty in understanding the source of a problem. Below is a listing of the model classes. Essentially the goal is to have the ability to add sentences to the end of the story, or to add stories to an existing sentence_block. Right now, I'm only attempting to allow users to add sentences, and automatically create a new sentence_block for the new sentence. class Story < ActiveRecord::Base has_many :sentence_blocks, :dependent => :destroy has_many :sentences, :through => :sentence_blocks accepts_nested_attributes_for :sentence_blocks end class SentenceBlock < ActiveRecord::Base belongs_to :story has_many :sentences, :dependent => :destroy end class Sentence < ActiveRecord::Base belongs_to :sentence_block def story @sentence_block = SentenceBlock.find(self.sentence_block_id) Story.find(@sentence_block.story_id) end end The problem is occurring when using the show method of the Story. The Story method is as follows, and the associated show method for a sentence is also included. Sentence.show def show @sentence = Sentence.find(params[:id]) respond_to do |format| format.html {redirect_to(@sentence.story)} format.xml { render :xml => @sentence } end end Story.show def show @story = Story.find(params[:id]) @sentence_block = @story.sentence_blocks.build @new_sentence = @sentence_block.sentences.build(params[:sentence]) respond_to do |format| if @new_sentence.content != nil and @new_sentence.sentence_block_id != nil and @sentence_block.save and @new_sentence.save flash[:notice] = 'Sentence was successfully added.' format.html # new.html.erb format.xml { render :xml => @story } else @sentence_block.destroy format.html format.xml { render :xml => @story } end end end I'm getting a "couldn't find Sentence_block without and id" error. So I'm assuming that for some reason the sentence_block isn't getting saved to the database. Can anyone help me with my understanding of the behavior and why I'm getting the error? I'm trying to ensure that every time the view depicts show for a story, an unnecessary sentence_block and sentence isn't created, unless someone submits the form, I'm not really sure how to accomplish this. Any help would be appreciated.

  • How to define an extern, C struct returning function in C++ using MSVC?

    - by DK
    The following source file will not compile with the MSVC compiler (v15.00.30729.01): /* stest.c */ #ifdef __cplusplus extern "C" { #endif struct Test; extern struct Test make_Test(int x); struct Test { int x; }; extern struct Test make_Test(int x) { struct Test r; r.x = x; return r; } #ifdef __cplusplus } #endif Compiling with cl /c /Tpstest.c produces the following error: stest.c(8) : error C2526: 'make_Test' : C linkage function cannot return C++ class 'Test' stest.c(6) : see declaration of 'Test' Compiling without /Tp (which tells cl to treat the file as C++) works fine. The file also compiles fine in DigitalMars C and GCC (from mingw) in both C and C++ modes. I also used -ansi -pedantic -Wall with GCC and it had no complaints. For reasons I will go into below, we need to compile this file as C++ for MSVC (not for the others), but with functions being compiled as C. In essence, we want a normal C compiler... except for about six lines. Is there a switch or attribute or something I can add that will allow this to work? The code in question (though not the above; that's just a reduced example) is being produced by a code generator. As part of this, we need to be able to generate floating point nans and infinities as constants (long story), meaning we have to compile with MSVC in C++ mode in order to actually do this. We only found one solution that works, and it only works in C++ mode. We're wrapping the code in extern "C" {...} because we want to control the mangling and calling convention so that we can interface with existing C code. ... also because I trust C++ compilers about as far as I could throw a smallish department store. I also tried wrapping just the reinterpret_cast line in extern "C++" {...}, but of course that doesn't work. Pity. There is a potential solution I found which requires reordering the declarations such that the full struct definition comes before the function foward decl., but this is very inconvenient due to the way the codegen is performed, so I'd really like to avoid having to go down that road if I can.
