    - by Gendaful
    I am a new bee to sencha 2.I wanted to run a basic application using sencha touch but unable to load the application. Here is what I have done. I have downloaded the notesApp from miamicoder and i am trying to run the first chapter. I have attached the folder structure in the screenshot. Please have a look to understand the folder structure. Here is my index.html <!DOCTYPE html> <html> <head> <title>My Notes</title> <link href="sencha-touch.css" rel="stylesheet" type="text/css" /> <script src="sencha-touch-debug.js" type="text/javascript"></script> <script src="app.js" type="text/javascript"></script> </head> <body> </body> </html> I have downloaded sencha sdk 2.1 and took sencha-touch-debug.js and sencha-touch.css and placed in the root of the folder and referred from index.html as mentioned below. I used to to the same thing in sencha 1 and I was getting success but I am getting below error if I am trying to do the same with sencha 2. I am getting errors as below.

  • Gap appears between navigation bar and view after rotating & tab switching

    - by Bogatyr
    My iphone application is showing strange behavior when rotating: a gap appears between the navigation title and content view inside a tab bar view (details on how to reproduce are below). I've created a tiny test case that exhibits the same problem: a custom root UIViewController, which creates and displays a UITabBarController programmatically, which has two tabs: 1) plain UIViewController, and 2) UINavigationController created programmatically with a single plain UIViewController content view. The complete code for the application is in the root controller's viewDidLoad (every "*VC" class is a totally vanilla UIViewController subclass with XIB for user interface from XCode, with only the view background color changed to clearly identify each view, nothing else). Here's the viewDidLoad code, and the shouldAutorotateToInterfaceOrientation code, this code is the entire application basically: - (void)viewDidLoad { [super viewDidLoad]; FirstVC *fvc = [[FirstVC alloc] initWithNibName:@"FirstVC" bundle:nil]; NavContentsVC *ncvc = [[NavContentsVC alloc] initWithNibName:@"NavContentsVC" bundle:nil]; UINavigationController *svc = [[UINavigationController alloc] initWithRootViewController:ncvc]; NSMutableArray *localControllersArray = [[NSMutableArray alloc] initWithCapacity:2]; [localControllersArray addObject:fvc]; [localControllersArray addObject:svc]; fvc.title = @"FirstVC-Title"; ncvc.title = @"NavContents-Title"; UITabBarController *tbc = [[UITabBarController alloc] init]; tbc.view.frame = CGRectMake(0, 0, 320, 460); [tbc setViewControllers:localControllersArray]; [self.view addSubview:tbc.view]; [localControllersArray release]; [ncvc release]; [svc release]; [fvc release]; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } Here's how to reproduce the problem: 1) start application 2) rotate device (happens in simulator, too) to landscape (UITabBar properly rotates) 3) click on tab 2 4) rotate device to portrait -- notice gap of root view controller's background color of about 10 pixels high beneath the Navigation title bar and the Navigation content view. 5) click tab 1 6) click tab 2 And the gap is gone! From my real application, I see that the gap remains during all VC push and pops while the NavigationController tab is active. Switching away to a different tab and back to the Nav tab clears up the gap. What am I doing wrong? I'm running on SDK 3.1.3, this happens both on the simulator and on the device. Except for this particular sequence, everything seems to work fine. Help!

  • PHP does not return errors at all

    - by ErJab
    I am running PHP and nginx and I use a production version of php.ini. So the variable display_error is set to Off and there is a good reason I want it this way. But for certain files I need to enable error reporting. I used ini_set to turn on error reporting. But a simple code snippet like: <?php error_reporting(E_ALL); ini_set("display_errors", 1); echo "hi"errorrrrr ?> does not trace the error. It simply returns a HTTP 500 Internal Server Error message. What should I do to enable error reporting?

  • ASP.NET - Overriding Gridview OnRowCreated to add sort images -- columns are null

    - by Zach
    I'm overriding the onrowcreated to add sort images to the header row of a gridview. This works, but actually adding a sortexpression doesn't. What I want to do is set the images as imagebuttons and set their commandarguments to the sort expression of the column they are sorting for. I would assume I could get the cell and from it's index get the gridviewcolumn. Then, I could just get the sortexpression of the gridview column, but this does not work. The columns are null. OnRowCreated Code snippet below: //if this is the header row, we add sort images to each cell if (row.RowType == DataControlRowType.Header) { //iterate through the cells for (int i = 0; i < row.Cells.Count; i++) { //if the column is sortable and visible if (this.Columns[i].SortExpression != string.Empty && this.Columns[i].Visible) { string strSort = this.Columns[i].SortExpression; } } } Can we not get columns in OnRowCreated like this?

  • Fairness: Where can it be better handled?

    - by Srinivas Nayak
    Hi, I would like to share one of my practical experience with multiprogramming here. Yesterday I had written a multiprogram. Modifications to sharable resources were put under critical sections protected by P(mutex) and V(mutex) and those critical section code were put in a common library. The library will be used by concurrent applications (of my own). I had three applications that will use the common code from library and do their stuff independently. my library --------- work_on_shared_resource { P(mutex) get_shared_resource work_with_it V(mutex) } --------- my application ----------- application1 { *[ work_on_shared_resource do_something_else_non_ctitical ] } application2 { *[ work_on_shared_resource do_something_else_non_ctitical ] } application3 { *[ work_on_shared_resource ] } *[...] denote a loop. ------------ I had to run the applications on Linux OS. I had a thought in my mind, hanging over years, that, OS shall schedule all the processes running under him with all fairness. In other words, it will give all the processes, their pie of resource-usage equally well. When first two applications were put to work, they run perfectly well without deadlock. But when the third application started running, always the third one got the resources, but since it is not doing anything in its non-critical region, it gets the shared resource more often when other tasks are doing something else. So the other two applications were found almost totally halted. When the third application got terminated forcefully, the previous two applications resumed their work as before. I think, this is a case of starvation, first two applications had to starve. Now how can we ensure fairness? Now I started believing that OS scheduler is innocent and blind. It depends upon who won the race; he got the largest pie of CPU and resource. Shall we attempt to ensure fairness of resource users in the critical-section code in library? Or shall we leave it up to the applications to ensure fairness by being liberal, not greedy? To my knowledge, adding code to ensure fairness to the common library shall be an overwhelming task. On the other hand, believing on the applications will also never ensure 100% fairness. The application which does a very little task after working with shared resources shall win the race where as the application which does heavy processing after their work with shared resources shall always starve. What is the best practice in this case? Where we ensure fairness and how? Sincerely, Srinivas Nayak

  • C++ Program Always Crashes While doing a std::string assign

    - by bbazso
    I have been trying to debug a crash in my application that crashes (i.e. asserts a * glibc detected free(): invalid pointer: 0x000000000070f0c0 **) while I'm trying to do a simple assign to a string. Note that I'm compiling on a linux system with gcc 4.2.4 with an optimization level set to -O2. With -O0 the application no longer crashes. E.g. std::string abc; abc = "testString"; but if I changed the code as follows it no longer crashes std::string abc("testString"); So again I scratched my head! But the interesting pattern was that the crash moved later on in the application, AGAIN at another string. I found it weird that the application was continuously crashing on a string assign. A typical crash backtrace would look as follows: #0 0x00007f2c2663bfb5 in raise () from /lib64/libc.so.6 (gdb) bt #0 0x00007f2c2663bfb5 in raise () from /lib64/libc.so.6 #1 0x00007f2c2663dbc3 in abort () from /lib64/libc.so.6 #2 0x00000000004d8cb7 in people_streamingserver_sighandler (signum=6) at src/peoplestreamingserver.cpp:487 #3 <signal handler called> #4 0x00007f2c2663bfb5 in raise () from /lib64/libc.so.6 #5 0x00007f2c2663dbc3 in abort () from /lib64/libc.so.6 #6 0x00007f2c26680ce0 in ?? () from /lib64/libc.so.6 #7 0x00007f2c270ca7a0 in std::string::assign (this=0x7f2c21bc8d20, __str=<value optimized out>) at /home/bbazso/ThirdParty/sources/gcc-4.2.4/x86_64-pc-linux-gnu/libstdc++-v3/include/bits/basic_string.h:238 #8 0x00007f2c21bd874a in PEOPLESProtocol::GetStreamName (this=<value optimized out>, pRawPath=0x2342fd8 "rtmp://127.0.0.1/mp4:pop.mp4", lStreamName=@0x7f2c21bc8d20) at /opt/trx-HEAD/gcc/4.2.4/lib/gcc/x86_64-pc-linux-gnu/4.2.4/../../../../include/c++/4.2.4/bits/basic_string.h:491 #9 0x00007f2c21bd9daa in PEOPLESProtocol::SignalProtocolCreated (pProtocol=0x233a4e0, customParameters=@0x7f2c21bc8de0) at peoplestreamer/src/peoplesprotocol.cpp:240 This was really weird behavior and so I started to poke around further in my application to see if there was some sort of memory corruption (either heap or stack) error that could be occurring that could be causing this weird behavior. I even checked for ptr corruptions and came up empty handed. In addition to visual inspection of the code I also tried the following tools: Valgrind using both memcheck and exp-ptrcheck electric fence libsafe I compiled with -fstack-protector-all in gcc I tried MALLOC_CHECK_ set to 2 I ran my code through lint checks as well as cppcheck (to check for mistakes) And I stepped through the code using gdb So I tried a lot of stuff and still came up empty handed. So I was wondering if it could be something like a linker issue or a library issue of some sort that could be causing this problem. Are there any know issues with the std::string that make is susceptible to crashing in -O2 or maybe it has nothing to do with the optimization level? But the only pattern that I can see thus far in my problem is that it always seems to crash on a string and so I was wondering if anyone knew of any issues that my be causing this type of behavior. Thanks a lot!

  • What defines writing PHP?

    - by cdburgess
    When writing PHP code for any given project, do you find you can write code off the top of your head? Or do you make multiple round trips to php.net? If it is the later, can you still be considered a good coder. This is a legitimate question as I find I have difficulty always remembering all of the functions that are available to me so I find I use php.net as a crutch. Is there anyway to improve this?

  • compiler warning at C++ template base class

    - by eike
    I get a compiler warning, that I don't understand in that context, when I compile the "Child.cpp" from the following code. (Don't wonder: I stripped off my class declarations to the bare minuum, so the content will not make much sense, but you will see the problem quicker). I get the warning with VS2003 and VS2008 on the highest warning level. The code AbstractClass.h : #include <iostream> template<typename T> class AbstractClass { public: virtual void Cancel(); // { std::cout << "Abstract Cancel" << std::endl; }; virtual void Process() = 0; }; //outside definition. if I comment out this and take the inline //definition like above (currently commented out), I don't get //a compiler warning template<typename T> void AbstractClass<T>::Cancel() { std::cout << "Abstract Cancel" << std::endl; } Child.h : #include "AbstractClass.h" class Child : public AbstractClass<int> { public: virtual void Process(); }; Child.cpp : #include "Child.h" #include <iostream> void Child::Process() { std::cout << "Process" << std::endl; } The warning The class "Child" is derived from "AbstractClass". In "AbstractClass" there's the public method "AbstractClass::Cancel()". If I define the method outside of the class body (like in the code you see), I get the compiler warning... AbstractClass.h(7) : warning C4505: 'AbstractClass::Cancel' : unreferenced local function has been removed with [T=int] ...when I compile "Child.cpp". I do not understand this, because this is a public function and the compiler can't know if I later reference this method or not. And, in the end, I reference this method, because I call it in main.cpp and despite this compiler warning, this method works if I compile and link all files and execute the program: //main.cpp #include <iostream> #include "Child.h" int main() { Child child; child.Cancel(); //works, despite the warning } If I do define the Cancel() function as inline (you see it as out commented code in AbstractClass.h), then I don't get the compiler warning. Of course my program works, but I want to understand this warning or is this just a compiler mistake? Furthermore, if do not implement AbsctractClass as a template class (just for a test purpose in this case) I also don't get the compiler warning...?

    Hello I just can't get this thing. How is ZeroClipboard supposed to work? Why does it need to move the flash-element over the copied text? I've read this thing: http://code.google.com/p/zeroclipboard/wiki/Instructions Can someone provide me a short snippet, which makes it possible to copy a text in variable to users clipboard, when user clicks a link. Is this even possible? I don't care, if it doesn't work on all browsers (IE6 for example). I'm using jQuery. Martti Laine

  • IE6 Bug - Div within Anchor tag: inline images not links

    - by thorn100
    I'm trying to get everything in the anchor tag to be a clickable link. Unfortunately, in IE6 (which is the only browser I'm concerned with currently), the only thing that isn't a clickable link are the inline images. I know that it's not valid html to put a div inside of an anchor but it's not my markup and I've been asked to avoid changing it. Any suggestions to altering the CSS to enable the images as clickable links? If changing the markup is the only solution... any suggestions there? My initial thought was to set the image as a background of it's parent (.ph-item-featured-img), although I'm unclear if that will solve the problem. Thanks! <div class="tab-panel-init clear ui-tabs-panel ui-widget-content ui-corner-bottom" id="ph-flashlights"> <a href="#" class="last ph-item-featured clear"> <div class="ph-item-featured-img"> <img src="#"> &nbsp; </div> <strong> PRODUCT CODE </strong> <p> PRODUCT CODE Heavy Duty Aluminum Led Flashlight </p> <span>Learn more &gt;</span> </a> <a href="#" class="last ph-item-featured clear"> <div class="ph-item-featured-img"> <img src="#"> &nbsp; </div> <strong> PRODUCT CODE </strong> <p> PRODUCT CODE Heavy Duty Aluminum Led Flashlight </p> <span>Learn more &gt;</span> </a> </div>

  • var undefined = true;

    - by Andreas Grech
    I'm doing some experimenting with this malicious JavaScript line: var undefined = true; Every uninitialized variable in JavaScript has the value of undefined which is just a variable that holds the special value of 'undefined', so the following should execute the alert: var undefined = true, x; if (x) { alert('ok'); } But it doesn't, and my question is why? On further experimentation, I tried the following: var undefined = true, x = undefined; if (x) { alert('ok'); } This time, the alert is executed. So my question is...since in the first snippet x holds undefined (because it is not initialized), why didn't the alert execute? The strange thing is that when explicitly stating that x is undefined (x = undefined), the alert executed...

  • Printf in assembler doesn't print

    - by Gaim
    Hi there, I have got a homework to hack program using buffer overflow ( with disassambling, program was written in C++, I haven't got the source code ). I have already managed it but I have a problem. I have to print some message on the screen, so I found out address of printf function, pushed address of "HACKED" and address of "%s" on the stack ( in this order ) and called that function. Called code passed well but nothing had been printed. I have tried to simulate the environment like in other place in the program but there has to be something wrong. Do you have any idea what I am doing wrong that I have no output, please?

  • Issue with multipart upload in servlet on seam

    - by stacker

I refer to the function heading the string that looks like this: int someFunction(int i, int b) {
