  • adding a UIScrollView as a superview of 2 UITextview

    - by Risma
    hi i have 2 textview in a viewcontroller. the 1st textview is not editable, but the 2nd is editable. i want to make both of them scroll in the same position and size when the keyboard is appear. I think i have to use UIScrollView as base of both of textview. And then i add the UIScrollView in xib (bot of textview are made in xib too). and this is the picture if this hierarchy : in the viewDidLoad method, i add this code : - (void)viewDidLoad { [super viewDidLoad]; [scrollTextView addSubview:lineNumberTextView]; [scrollTextView addSubview:_codeTextView]; [lineNumberTextView bringSubviewToFront:scrollTextView]; [_codeTextView bringSubviewToFront:scrollTextView]; } but when i tap on the 2nd textview, the keyboard is not appear. What i have to do? thx for the advices

  • Why would a 'public event EventHandler cccc' be null?

    - by Matt
    Why would a 'public event EventHandler cccc' be null? I have a class that's public class Builder { public event EventHandler StartedWorking; public Builder() { // Constructor does some stuff } public void Start() { StartedWorking(this, eventargobject); //StartedWorking is null -- } } This seems straightforward and something I do all the time? Am I missing something obvious or is there something that could cause this? EDIT: Does this mean that if I fire an event that is not subscribed to in a client class I have to check that it is not null? EDIT-2: I guess I'd never had events that were never not subscribed to and hence never ran into this -- You learn something new every day Sorry about the seemingly stupid question....

  • jEdit+JythonInterpreter: how to import java class?

    - by JChao
    Hi, I'm running jEdit with the JythonInterprete and I have a .jar file called JavaTest.jar. JavaTest has a class called SampleJavaClass which has a method printerCount. From my .py file, I want to do: from javatest import SampleJavaClass class SampleClass(SampleJavaClass): def pymain(self): SampleJavaClass.printerCount(4) Java code: package javatest; public class SampleJavaClass { public static void printerCount(int i){ for(int j=0; j< i; j++){ System.out.println("hello world"); } } (etc...) In the JythonInterpreter, I have already tried clicking "Edit Jython Path" and adding the .jar file then running the interpreter again, but it still gives me ImportError: cannot import name SampleJavaClass

  • How to increment a value using a C-Preprocessor?

    - by mystify
    Example: I try to do this: static NSInteger stepNum = 1; #define METHODNAME(i) -(void)step##i #define STEP METHODNAME(stepNum++) @implementation Test STEP { // do stuff... [self nextFrame:@selector(step2) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step3) afterDelay:1]; } STEP { // do stuff... [self nextFrame:@selector(step4) afterDelay:1]; } // ... When building, Xcode complains that it can't increment stepNum. This seems logical to me, because at this time the code is not "alive" and this pre-processing substitution stuff happens before actually compiling the source code. Is there another way I could have an variable be incremented on every usage of STEP macro, the easy way?

  • (C++) If statement not effective

    - by Galileo
    void spriteput(int x,int y, int stype) { char sprite1[5]="OOOO"; char sprite2[5]="OOOO"; char sprite3[5]="OOOO"; char sprite4[5]="OOOO"; if (stype == 1) { char sprite1[5] = " OO "; char sprite2[5] = "OOOO"; char sprite3[5] = "OOOO"; char sprite4[5] = " OO "; mvprintw(2,y,"%s \n",sprite1); } mvprintw(x+1,y,"%s \n",sprite2); mvprintw(x+2,y,"%s \n",sprite3); mvprintw(x+3,y,"%s \n",sprite4); } If I'm correct that block of code should print out on a NCURSES screen OO OOOO OOOO OO Instead however, it prints out the default text (the first char statements). Can anyone tell me why this is? The "printw" statement inside the If-block prints out the proper text, so it's being assigned correctly. Thank you in advance.

  • how do i close a frame yet open a new frame?(revisited)

    - by altvali
    I'm new at Java and I'm trying to do what the title says, my application has page A, a jpanel with some controls and a specific button, and when the user clicks the button i want page A to disappear and page B to appear (page B has controls that depend on the choices that are made by the user on page A). This has been asked before but there was no satisfactory answer. In the ActionListener implementation, namely public void ActionPerformed(ActionEvent e) from my jpanelForPageA class i can comfortably write this.setVisible(false), but how can i set page B to a visible state?

  • Pushing UIViewController onto a UINavigationController

    - by Gregg
    The other day I asked about using a UINavigationController as a child of a UIViewController. I got that working via the answer. Now what I'm trying to do is push a controller onto the nav stack. When a table cell is touched, I do the following: - (void) showSetup { NSLog(@"Showing Setup"); SetupViewController *controller = [[SetupViewController alloc]initWithNibName:@"SetupViewController" bundle:nil]; self.setupViewController = controller; self.setupViewController.title = @"Setup"; [self.navigationController pushViewController:self.setupViewController animated:YES]; [controller release]; } I can see the log statement in my console, but the view never changes. Am I missing something?

  • Is it possible to use RedirectToAction() inside a custom AuthorizeAttribute class?

    - by Lance McNearney
    Using ASP.Net MVC 2, is there any way to use the RedirectToAction() method of the Controller class inside a class that is based on the AuthorizeAttribute class? public class CustomAttribute : AuthorizeAttribute { protected override bool AuthorizeCore(HttpContextBase context) { // Custom authentication goes here return false; } public override void OnAuthorization(AuthorizationContext context) { base.OnAuthorization(context); // This would be my ideal result context.Result = RedirectToAction("Action", "Controller"); } } I'm looking for a way to re-direct the user to a specific controller / action when they fail the authentication instead of returning them to the login page. Is it possible to have the re-direct URL generated for that controller / action and then use RedirectResult()? I'm trying to avoid the temptation to just hard-code the URL.

  • Why timed lock doesnt throws a timeout exception in C++0x?

    - by Vicente Botet Escriba
    C++0x allows to lock on a mutex until a given time is reached, and return a boolean stating if the mutex has been locked or not. template <class Clock, class Duration> bool try_lock_until(const chrono::time_point<Clock, Duration>& abs_time); In some contexts, I consider an exceptional situation that the locking fails because of timeout. In this case an exception should be more appropriated. To make the difference a function lock_until could be used to get a timeout exception when the time is reached before locking. template <class Clock, class Duration> void lock_until(const chrono::time_point<Clock, Duration>& abs_time); Do you think that lock_until should be more adequate in some contexts? if yes, on which ones? If no, why try_lock_until will always be a better choice?

  • How to keep a Generic list unmodified when its copy is modified?

    When I create a copy of the original list lstStudent in lstCopy and send the lstCopy to modification function, the lstStudent also gets modified. I want to keep this list unmodified.

  • Objective C: App freezes when using a timer

    - by Chris
    It took me hours to figure out how to implement a timer into my program, but when it runs, the app doesn't load completely as it did before the timer. In my main.m: int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; OutLauncher *theLauncher = [[OutLauncher alloc] init]; NSTimer *theTimer = [theLauncher getTimer]; [theTimer retain]; [[NSRunLoop currentRunLoop] addTimer: theTimer forMode: NSDefaultRunLoopMode]; [[NSRunLoop currentRunLoop] run]; [pool release]; return 0; } The file OutLauncher is being imported into that, which looks like this: - (void)doStuff { NSLog( @"Doing Stuff"); } - (NSTimer *)getTimer{ NSTimer *theTimer; theTimer = [NSTimer scheduledTimerWithTimeInterval:1.0 target:self selector: @selector(doStuff) userInfo:nil repeats:YES]; return [theTimer autorelease]; } The timer works, the console updates every second with the phrase "doing stuff" but the rest of the program just won't load. It will if I comment out the code I added to int main though

  • c: memory allocation (what's going on)

    - by facha
    Hi, everyone Please take a look at this piece of code. I'm allocating one byte for the first variable and another byte for the second one. However, it seems like the compiler allocates more (or I'm missing something). The program outputs both strings, even though their length is more the one byte. void main() { char* some1 = malloc(1); sprintf(some1,"cool"); char* some2 = malloc(1); sprintf(some2,"face"); printf("%s ",some1); printf("%s\n",some2); } Please, could anyone spot some light on what's going on when memory is being allocated.

  • Problem with default member functions of class in C++ (constructor, destructor, operator=, copy cons

    - by Narek
    We know that compiler generates some member functions for user-defined class if that member functions are not defined but used, isn't it. So I have this kind of code: class AA { }; void main() { AA a; AA b(a); a = b; } This code works fine. I mean no compiler error. But the following code.... class AA { int member1; int member2; }; But this code gives an run time error, because variable "a" is used without being iniltialized!!! So my question is this: when we instantiate an int, it has a value. So why the default constructer doesn't work and by using those two int numbers initializes variable "a"??

Why ?

  • __FILE__ In .h what does it resolve to

    - by Pablitorun
    Is there a specification on how the FILE macro will be expanded if it is in a .h? So if I #define MYFILE __FILE__ in foo.h and foo.c #includes "foo.h" void main(){ printf("%s",MYFILE); .... does this output foo.h or foo.c? (Yes I realize this is a stupid example) Sorry for what should be a simple question. The documentation on the web seems conflicting. For what it is worth VS2008 comes back as foo.c which is what I would expect....I think. I am just trying to confirm if this is defined behavior.
