  • buffer overflow with boost::program_options

    - by f4
    Hello, I have a problem using boost:program_options this simple program, copy-pasted from boosts' documentation : #include <boost/program_options.hpp> int main( int argc, char** argv ) { namespace po = boost::program_options; po::options_description desc("Allowed options"); desc.add_options() ("help", "produce help message") ("compression", po::value<int>(), "set compression level") ; return 0; } fails with a buffer overflow. I have activated the "buffer security switch", and when I run it I get an "unknown exception (0xc0000409)" when I step over the line desc.add_options()... I use Visual Studio 2005 and boost 1.43.0. By the way it does run if I deactivate the switch but I don't feel comfortable doing so... unless it's possible to deactivate it locally. So do you have a solution to this problem? EDIT I found the problem I was linking against libboost_program_options-vc80-mt.lib which wasn't the good library.

  • Why is it so hard to find a C++ 3d game tutorial

    - by Dave
    I'm planning on learning 3d game development for the iphone using a 3d engine, but because of lack of tutorials for the iphone I was planning on using C++ game tutorials and making the necessary changes. The problem is that I've had limited success when searching for things such as 'c++ 3d fps tutorial ' I dont really get anything useful. Are there any 3d c++ tutorials you can recommend?

  • Why I can't draw in a loop? (Using UIView in iPhone)

    - by Tattat
    I can draw many things using this : NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"dummy2.png" ofType:nil]; UIImage *img = [UIImage imageWithContentsOfFile:imagePath]; image = CGImageRetain(img.CGImage); CGRect imageRect; double x = 0; double y = 0; for (int k=0; k<someValue; k++) { x += k; y += k; imageRect.origin = CGPointMake(x, y); imageRect.size = CGSizeMake(25, 25); CGContextDrawImage(UIGraphicsGetCurrentContext(), imageRect, image); } } CGImageRelease(img.CGImage); So, it works, so, I put it into a command object's execute method. Then, I want to do similar thing, but this time, my execute method only do this: NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"dummy2.png" ofType:nil]; UIImage *img = [UIImage imageWithContentsOfFile:imagePath]; image = CGImageRetain(img.CGImage); CGRect imageRect; double x = inComingX; double y = inComingY; imageRect.origin = CGPointMake(x, y); imageRect.size = CGSizeMake(25, 25); CGContextDrawImage(UIGraphicsGetCurrentContext(), imageRect, image); CGImageRelease(img.CGImage); This time, this is also a Command, and it is the execute method. But I take the for loop away. I will have another method that pass the inComingX , and inComingY into my Command object. My Drawing method is simply execute the Cmd that passed in my drawingEngine: -(void)drawInContext:(CGContextRef)context { [self.cmdToBeExecuted execute]; } I also have the assign method to assign the command,: -(void)assignCmd:(Command* )cmd{ self.cmdToBeExecuted = cmd; } And this is the way I called the drawingEngine for(int k=0; k<5; k++){ [self.drawingEngine assignCmd:[DrawingCmd setDrawingInformation:(10*k):0:@"dummy.png"]]; [self.drawingEngine setNeedsDisplay]; } It can draw, but the sad thing is it only draw the last one. Why? and how to fix it? I can draw all the things in my First code, but after I take the loop outside, and use the loop in last code, it just only draw the last one. Plz help

  • Copying a byte buffer with JNI

    - by Daniel
    I've found plenty of tutorials / questions on Stackoverflow that deal with copying char arrays from C/JNI side into something like a byte[] in Java, but not the other way around. I am using a native C library which expects a byte array. I simply want to get data from a byte[] in java, into preferably an unsigned char[] in C. Long story short: What is the best way of copying data from a jBytearray in JNI? Is there any way to detect it's size?

  • How to change the UIImageView image content by code?

    - by Tattat
    I use this to assign image: UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImage" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; imageView.image = [UIImage imageWithCGImage:imageRef]; [self addSubview:imageView]; CGImageRelease(imageRef); Now, I want to change the image from myImage to myImage2, so I do that: UIImage *img = [UIImage imageWithContentsOfFile: [[NSBundle mainBundle] pathForResource:@"myImage2" ofType:@"png"]]; CGRect cropRect = CGRectMake(175, 0, 175, 175); CGImageRef imageRef = CGImageCreateWithImageInRect([img CGImage], cropRect); imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 175, 175)]; imageView.image = [UIImage imageWithCGImage:imageRef]; [self addSubview:imageView]; It works, but not the way I want, I want to change the image, not add a imageView on top of the pervious one. How can I modify my code? thx u.

  • Objective-C properties are not being recognized in header file?

    - by Greg
    Hey folks, I wonder if I'm doing something completely stupid here... I'm clearly missing something. I've gotten used to the pattern of defining properties of a custom class, however I seem to be hitting a point where extended classes do not recognize new properties. Case of point, here's my header file: import import "MyTableViewController.h" @interface MyRootController : MyTableViewController { NSMutableArray *sectionList; } @property (nonatomic, retain) NSMutableArray *sectionList; @end Now, for some reason that "sectionList" property is not turning green within my interface file (ie: it's not being recognized as custom property it seems). As a result, I'm getting all kinds of errors down in my implementation. The first is right at the top of my implementation where I try to synthesize the property: import "MyRootController.h" @implementation MyRootController @synthesize sectionList; That synthesize line throws the error "No declaration of property 'sectionList' found in the interface". So, this is really confusing. I'm clearly doing something wrong, although I can't put my finger on what. One thought: I am extending another custom class of my own. Do I need to specify some kind of super-class declaration to keep the architecture from getting sealed one level up? Thanks!

  • Crystal Reports and WMF image

    - by Eve
    I have a problem with inserting a vector graphics (WMF) into report (Crystal Reports v10.5 from Visual Studio 2008). The image is static, inserted by choosing "Insert Picture" during report design in VS. The problem is that it displays differently (size and aspect ratio) on machines with different operating systems and screen resolutions. Converting to bitmap isn't possible beacause loss of the quality of print isn't acceptable. I thought about dynamic loading of the image, but in this version of CR. I don't see a possibility to set dynamic graphic location in picture properties. Is there any way to solve this problem?

  • How can I remove the present view when I have added more than one subView ?

    - by srikanth rongali
    How can I remove the present view when I touched the close button. I did [self.view removeFromSuperView] when I added only one subView. It worked. But, I have now added another subView to the previous subView. I need to to get the parent view . How can I do it. My code of adding the subView is here. When I did the following only one view is removed. //FirstViewController: UIViewController -(void)libraryFunction:(id)sender { LibraryController *libraryController = [[LibraryController alloc]init]; [self.view addSubview:libraryController.view]; } //LibraryController: UIViewController -(void)viewDidLoad{ RootViewController *rootViewController = [[RootViewController alloc] initWithStyle:UITableViewStylePlain]; UINavigationController *aNavigationController = [[UINavigationController alloc] initWithRootViewController:rootViewController]; self.navController = aNavigationController; [aNavigationController release]; [rootViewController release]; [self.view addSubview:navController.view]; } //RootViewController: UITableViewController - (void)viewDidLoad { [super viewDidLoad]; self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Close" style:UIBarButtonItemStyleBordered target:self action:@selector(close:)]; } -(void)close:(id)sender { [self.view removeFromSuperview]; } Thank You.

  • How can I get .NET/Silverlight source code symbols to work in VS 2010?

    - by mattx
    Back when M$ first released the ability to point visual studio at a symbol server and actually debug into .NET code I got it up and working no problem on VS2008. Now trying to do this with VS2010 or my local copy of VS2008 doesn't seem to work. It successfully downloads the symbols and the stack frames turn from gray to black but there is no source available. Has anyone gotten this working? If so what's the secret? Also is there source available for Silverlight included?

  • Custom action getting published multiple times on user's timeline for same object

    - by serpent403
    I just noticed that when I publish an action on the user's timeline for the same object multiple times, using facebook's 'built-in' action type (eg: 'read' an article), i get an error response, something like "action is already associated to the user on this object". But when i try to do the same for a custom action that i created(eg: 'agreed' with an article), I don't get any error message, instead the actions gets published multiple times. I want my custom action to behave just like facebook's default action-type.

  • Child Activity in Android

    - by Martin Marinov
    So I have two Activities. The main is called Main, and the child one is called Child. When a button is clicked in the main activity it triggers the following piece of code: Intent i = new Intent(Main.this, Child.class); Main.this.startActivity(i); That opens the Child activity. As soon as I call finish() or press the back button within the child activity instead of going back to the main one, the app just closes. Can you give me a hint where the problem might be :( P.S. By trial and error I found out that if edit AndroidManifest.xml and add android:theme="@android:style/Theme.Dialog" within the declaration of Child the back button and calling finish() behaves as expected: closes the child activity and brings the main into focus. The problem is that when I start typing in an EditText the screen starts flickering (rather bizzare). So I can't use it as a dialog. My main activity uses the camera, so that might be making problems. Although when the child activity is started, the onPause event is fired and it stops the camera until onResume is called.

  • Render only a portion of a PDF on iPhone/iPad

    - by Infinity
    Hello guys! I am rendering my pdf in an UIView's drawRect method. Here's my code: - (void)drawRect:(CGRect)rect2 { NSString *filename = @"lol.pdf"; CFStringRef path = CFStringCreateWithCString (NULL, [filename UTF8String], kCFStringEncodingUTF8); CFURLRef url = CFURLCreateWithFileSystemPath (NULL, path, kCFURLPOSIXPathStyle, 0); CGPDFDocumentRef pdf = CGPDFDocumentCreateWithURL(url); CGPDFPageRef page = CGPDFDocumentGetPage (pdf, 1); CGAffineTransform m; CGContextRef context = UIGraphicsGetCurrentContext(); CGRect aRect = CGRectMake(0, 0, 768, 1024); CGContextTranslateCTM(context, 0.0, aRect.size.height); CGContextScaleCTM(context, 1.0, -1.0); m = CGPDFPageGetDrawingTransform (page, kCGPDFMediaBox, aRect, 0, YES); CGContextSaveGState (context); CGContextConcatCTM (context, m); CGContextClipToRect (context,CGPDFPageGetBoxRect (page, kCGPDFCropBox)); CGContextDrawPDFPage (context, page); CGContextRestoreGState (context); } It renders the whole pdf. How can I render only a part from it? Can you help me with it?

  • How big can I make an Android application's canvas in terms of pixels?

    - by user279112
    I've determined an estimate of the size of my Android emulator's screen in pixels, although I think its resolution can be changed to other numbers. Quite frankly though that doesn't eliminate the general problem of not knowing how many pixels on each axis I have to work with on my Android applications in general. The main problem I'm trying to solve is this: How do I make sure I don't use a faulty resolution on Android applications if I want to keep things' sizes constant (so that if the application screen shrinks, for instances, objects will still show up just as big - there just won't be as many of them being shown) if I wish to do this with a single universal resolution for each program? Failing that, how do I make sure everything's alright if I try to do everything the same way with maybe a few different pre-set resolutions? Mainly it seems like a relevant question that must be answered before I can come across a complete answer for the general problem is how big can I always make my application in pixels, NOT regarding if and when a user resizes the application's screen to something smaller than the maximum size permitted by the phone and its operating system. I really want to try to keep this simple. If I were doing this for a modern desktop, for instance, I know that if I design the application with a 800x600 canvas, the user can still shrink the application to the point they're not doing themselves any favors, but at least I can basically count on it working right and not being too big for the monitor or something. Is there such a magic resolution for Android, assuming that I'm designing for API levels 3+ (Android 1.5+)? Thanks

  • Why does the token returned by LogonUser() in Win x64 not belong to LOCAL group?

    - by edwinbs
    Hi, I have a piece of code that calls LogonUser() followed by CreateProcessAsUser(). In Win32, the resulting process belongs to a user (say, TESTDOMAIN\user1) who belongs to the LOCAL group. However, in x64, the process owner does not belong to LOCAL. The owner still belongs to all other groups (Authenticated Users, Everyone, etc.) Does anyone know if this is a documented behavior change? Or am I supposed to put some special flag in x64 when calling LogonUser()? Thanks.

  • touchesMoved QuartzDemo application

    - by BittenApple
    I am modifying the QuartzDemo application to include swipe detection while UIView is active (a PDF page being displayed in it via Quartz). This will not work, the event never gets to the QuartzView.m because it sits under scrollview? touchesBegan works fine and I can use single tap. How can I go about with catching touchesMoved while PDF page is being displayed? I need a simple example with code that does nothing on touchesMoved, I'll build up on that later. Please keep in mind that I still want to use the UIScrollview as it is and show PDF content based on selection in that scrollview.

  • Reverse geocode street name and city as text

    - by Taylor Satula
    Hello, I have been having some trouble finding a good way to output just the street name and city as text (Infinite Loop, Cupertino shown here) that can be displayed in my iPhone app. This needs to be able to dynamically change as you change streets and city. I don't have the slightest idea of how to do this, I hope someone can help. I have attached a very rough image of what I am trying to acheave. I have found this (http://code.google.com/apis/maps/documentation/javascript/services.html#Geocoding) for google maps about how to reverse geocode using javascript, but what I do not understand is how this would be done in a iPhone development setting. I work in web design and I see how it would be done in HTML but I am very new to iPhone development and don't have the slightest clue of how it would be done here. If someone could spell out how to do this I would be extremely grateful. I cannot seem to find what I am looking for by searching Google.

  • ImageViews sometimes not displaying in FrameLayout activity

    - by Ken
    The top level layout in my activity is a framelayout. I have completed, debugged and tested this app and it works exactly like it should in all respects on my g1 and on various emulators. But on 3.7-inch displays running 2.1+, some imageviews packed in a linearlayout are periodically not visible. I know that they are there because you can touch and drag them with effect in the app. So I assume somehow they have gotten under the SurfaceView that is the main component of the app. This is apparently so even though the SurfaceView is declared in the xml prior to the LinearLayout. However, the ImageViews IN the LinearLayout are added programmatically towards the end of onCreate(). Framelayout stacks everything that is added to it, one on top of the other--the only way you will see more than one child of a frame layout is if they are smaller than the screen and are placed apart from eachother. Oddly, sometimes the imageviews ARE visible--it is random. Anyway, I've been trying to combat this with framelayout.bringChildToFront(View v) on the linearlayout without success. I wonder if anyone has any insight into how the behavior could be random like that, and how I should code these imageviews to keep this from happening, and why the problem appears only to occur on 3.7 vs 3.2 inch screens (as it happens, the two 3.2-inch screens were both htc, so vendor might be factor too). [edit] Actually, I've determined that this is a 2.2 issue, not a screen size (or even vendor) issue. Can't ensure that ImageViews added to a framelayout with a SurfaceView in it will appear on top of the surfaceview. I ran some tests in the respective onDraw() methods and the imageviews are 'visible' (0), and nothing does anything to the alpha of the drawables, which are there as well at ondraw(). [/edit] Any insight would be welcomed. Ken T.

  • Broken if statement

    - by Vladimir Nani
    Maybe I am crazy but how that could be? some == null is always false but debugger goes into if-statement body anyway. Any ideas? I have restarted visual studio I have cleaned every bin/obj folder It is not the case that i don`t understand that WindowsIdentity.GetCurrent() may return null. That was my first idea. var some = new object(); if (some == null) { throw new Exception("hi!"); } else { do(); } My code: private void GetCurrentWindowsIdentity() { var identity = WindowsIdentity.GetCurrent() if (identity == null) { throw new Exception(Errors.IdentityIsNullException); } try { if (CurrentAuthenticationWrapper.AuthenticationType == AuthenticationType.Windows) { CurrentLogin = _identity != null ? _identity.Name : string.Empty; } } catch (Exception ex) { ViewManager.ShowError(ex); } _identity = identity; }
