  • overflow technique in stack

    - by metashockwave
    int main(void) { problem2(); } void doit2(void) { int overflowme[16]; //overflowme[37] =0; } void problem2(void) { int x = 42; doit2(); printf("x is %d\n", x); printf("the address of x is 0x%x\n", &x); } Would someone help me understand why overflowme[37] =0; from the doit2 function will overwrite the value of x? (please include Program Counter and Frame Pointer of the function doit2 in your explanation) Thank you! It works every time with Project properties-Configuration properties-C/C++ -Code Generation-Basic Runtime Checks set to "Default". so it's not an undefined behavior.

  • How do I dynamically create Flex 4 AddChild actions for States?

    - by TK Kocheran
    I have an application in which I need to create mx.states.State objects on the fly, as I'm reading external data in order to create the states. Each State only has a single child, so here's my code which I was using to accomplish this: var state:State = new State(); state.name = "a"; state.overrides = [new AddChild(parent, DisplayObject(view))]; this.states.push(state); However, when I actually change a state, I get a runtime error relating to the fact that you can't call addChild on a spark.components.Group component. Is there an equivalent AddElement action for adding elements to a Group during a state change?

  • How to make a resolution independent camera preview on android?

    - by histeria
    Hi all, I'm making an android 1.6 app that uses phone's camera. In order to do this app resolution independent, I need to set a compatible aspect ratio for previewing camera on a SurfaceLayout. In 1.6 sdk there is no way to get supported sizes for the camera preview. It is possible to use a 4:3 or 3:2 aspect ratio and get no errors whith that? On the other hand, I need a way to make a xml layout that represents this Surfacelayout in this (unknown) aspect ratio in every resolution. I assume that is not possible to change the SurfaceLayout size in runtime. Can I do it with "dp" units? The other way is making this layout programmatically? There are some apps like Vignette or android camera application with some tricks to make something like that, like black bars (vignette) or fixed buttons bar, but I don't know how to do it in any kind of resolution. Any ideas? Thanks!

  • MySQL: How to consume/discard the result of a query?

    - by GetFree
    I have a stored procedure which executes an optimize table statement for every table in a DB. Those optimize table statements are prepared statements of course (they have to be built at runtime) and I need to call that procedure from PHP using ext/mysql API. Unfortunately, ext/mysql does't support doing such thing because optimize table returns a result set and in order to handle that, the new mysql protocol is required, which is supported by the "new" ext/mysqli API. Well... there are several things I dont have control over, so it's not in my posibilities to upgrade to ext/mysqli any time soon, nor can I implement the procedure as PHP code rather than sql code. So I thought if it would be possible somehow to consume/discard the result of optimize table inside the stored procedure so that ext/mysql doesn't complain about it. One thing to consider is that since the optimize table statements are prepared statements, you can't use a cursor over them.

  • how to call a C++ dll from C# windows application project

    - by chathuradd
    I have created a dll in C++ using a Class Library project in Visual Studio. I need to call a method in the dll from a C# application. I got to know there are 2 approches. One is to add the dll project reference to C# project or use DllExport to export method. However when I tried in both ways it always gives the following error when the dll method is called in runtime. An unhandled exception of type 'System.BadImageFormatException' occurred in TestClient.exe Additional information: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) Can i know how to avoid this problem ? Thanks in advance!

  • OS monitoring using JAVA

    - by Puneri
    I'm planning to implement a framework for monitoring OS level resources: process network stats cpu info etc using JAVA. I see there is SIGAR API by Spring, which is implemented in native language and JAVA API being provided on top. But I will prefer not to have native stuff in my framework, rather for each OS will write a Java Class which will fetch required OS info by running system commands via JAVA Runtime. So I would like to have inputs/suggestions that one may have seen of not doing this in JAVA and use native app/api/jni. Any example will help for sure. I agree each OS has different commands to get these stats, but will prefer to have a Java Class per OS than have/load native code.

  • Qt "no matching function for call"

    - by Blin
    I have no matching function for call to 'saveLine::saveLine()' error when compiling my application. The construcor is never actually called. saveLine class definition: class saveLine { public: saveLine(QWidget *parent); private: QPushButton *selectButton, *acceptButton; QLabel *filePath; QLineEdit *allias; }; saveLine is used in another class which is defined as follows: class MWindow : public QWidget { Q_OBJECT public: MWindow(QWidget *parent=0); private: saveLine line1; }; error points to MWindow constructor implementation MWindow::MWindow(QWidget *parent):QWidget(parent) { this->setWindowTitle("Launcher"); this->resize(600,600); } What should i do? I intend to use saveLine class in a vector, to create lines at runtime.

  • How do you detect an area that can be filled in in a bitmap in ActionScript 3?

    - by 1.21 gigawatts
    I am having a tough time figuring this out. I need to be able to detect a fill area for something similar to a coloring book picture. The user will click inside the area that needs to be filled. The image is user created bitmap content and so the fill area must be detected at runtime. Any help would be tremendously appreciated! Posting Flex 4 code for review: <fx:Script> <![CDATA[ protected function myImage_clickHandler(event:MouseEvent):void { myImage.imageDisplay.bitmapData.floodFill(event.localX,event.localY,0xFFFFFF); } ]]> </fx:Script> <s:Image id="myImage" click="myImage_clickHandler(event)" source="/images/square.gif"/>

  • Read Velocity Tokens/Tag from .vm file

    - by user1801660
    I have an application where in I am trying to create a velocity template repository which will help me centralise all my email templates and will allow me to create a communication hub. All templates will be called at runtime and populates with data via services. My problem is that I need to provide users with optional and compulsory params list when they define the template inputs for the velocity template. Is there a way to read the tokens/tags from the velocity template file and extract them?? Like I want a list of tokens $name.address.streetName to be available to me from .vm file. I do not want to go for Regex . I do not have to cache or reuse them , its just going to be a one time read and store the default,compulsory & optional params in the database. I am following these patterns : http://kickjava.com/src/org/apache/velocity/test/view/TemplateNodeView.java.htm How to use String as Velocity Template? Please advice.

  • Using Boost statechart, how can I transition to a state unconditionally?

    - by nickb
    I have a state A that I would like to transition to its next state B unconditionally, once the constructor of A has completed. Is this possible? I tried posting an event from the constructor, which does not work, even though it compiles. Thanks. Edit: Here is what I've tried so far: struct A : sc::simple_state< A, Active > { public: typedef sc::custom_reaction< EventDoneA > reactions; A() { std::cout << "Inside of A()" << std::endl; post_event( EventDoneA() ); } sc::result react( const EventDoneA & ) { return transit< B >(); } }; This yields the following runtime assertion failure: Assertion failed: get_pointer( pContext_ ) != 0, file /includ e/boost/statechart/simple_state.hpp, line 459

  • "Make" system for Actionscript?

    - by Ender
    In working on larger Actionscript/Flash projects, I've started to really feel the need for some kind of "make" system, but I haven't found it yet. Does anyone know if it exists? Required features: Ability to associate SWCs with their source code and/or FLAs i.e. "this swc is compiled from this source" Ability to mark my current project as depending on these SWCs (either as compile-time or runtime libraries) A single, big shiny button, that when pressed does the following: Checks to see if any of the source files have changed, and if so, recompiles their associated SWCs Recompiles and relinks the main .swf, if necessary Runs the main .swf Have yet to find a way to get something like FlashDevelop to do this (but I don't know it well enough to be sure). Support for both code and FLA sources is preferred.

  • About first-,second- and third-class value

    - by forest58
    First-class value can be passed as an argument returned from a subroutine assigned into a variable. Second-class value just can be passed as an argument. Third-class value even can't be passed as an argument. Why should these things defined like that? As I understand, "can be passed as an argument" means it can be pushed into the runtime stack;"can be assigned into a variable" means it can be moved into a different location of the memory; "can be returned from a subroutine" almost has the same meaning of "can be assigned into a variable" since the returned value always be put into a known address, so first class value is totally "movable" or "dynamic",second class value is half "movable" , and third class value is just "static", such as labels in C/C++ which just can be addressed by goto statement, and you can't do nothing with that address except "goto" .Does My understanding make any sense? or what do these three kinds of values mean exactly?

  • Generically creating objects in C#

    - by DrLazer
    What I am trying to do is load in objects from an XML save file. The problem is those objects are configurable by the user at runtime, meaning i had to use reflection to get the names and attributes of those objects stored in an XML file. I am in the middle of a recursive loop through the XML and up to the part where I need to create an object then thought ..... ah - no idea how to do that :( I have an array stuffed with empty objects (m_MenuDataTypes), one of each possible type. My recursive loading function looks like this private void LoadMenuData(XmlNode menuDataNode) { foreach (object menuDataObject in m_MenuDataTypes) { Type menuDataObjectType = menuDataObject.GetType(); if (menuDataObjectType.Name == menuDataNode.Name) { //create object } } } I need to put some code where my comment is but I can't have a big switch statement or anything. The objects in my array can change depending on how the user has configured the app.

  • Are spinlocks a good choice for a memory allocator?

    - by dsimcha
    I've suggested to the maintainers of the D programming language runtime a few times that the memory allocator/garbage collector should use spinlocks instead of regular OS critical sections. This hasn't really caught on. Here are the reasons I think spinlocks would be better: At least in synthetic benchmarks that I did, it's several times faster than OS critical sections when there's contention for the memory allocator/GC lock. Edit: Empirically, using spinlocks didn't even have measurable overhead in a single-core environment, probably because locks need to be held for such a short period of time in a memory allocator. Memory allocations and similar operations usually take a small fraction of a timeslice, and even a small fraction of the time a context switch takes, making it silly to context switch in the case of contention. A garbage collection in the implementation in question stops the world anyhow. There won't be any spinning during a collection. Are there any good reasons not to use spinlocks in a memory allocator/garbage collector implementation?

  • Which parallel sorting algorithm has the best average case performance?

    - by Craig P. Motlin
    Sorting takes O(n log n) in the serial case. If we have O(n) processors we would hope for a linear speedup. O(log n) parallel algorithms exist but they have a very high constant. They also aren't applicable on commodity hardware which doesn't have anywhere near O(n) processors. With p processors, reasonable algorithms should take O(n/p log n/p) time. In the serial case, quick sort has the best runtime complexity on average. A parallel quick sort algorithm is easy to implement (see here and here). However it doesn't perform well since the very first step is to partition the whole collection on a single core. I have found information on many parallel sort algorithms but so far I have not seen anything pointing to a clear winner. I'm looking to sort lists of 1 million to 100 million elements in a JVM language running on 8 to 32 cores.

  • How can i create a ModalPopupExtender control dynamically from a server control?

    - by Colour Blend
    I have a composite server control that does quiet a number of things; one of which is to display a ModalPopup OnClick of a dynamically generated HtmlAnchor control. I need to create this ModalPopupExtender control dynamically in my server control and trigger it from within. I have been able to create it and trigger it from a button created at design time but not at runtime. This is as a result of the ID assign to the link is always not found by the ModalPopupExtender control. I have tried assigning a static ID but no success. Can anyone help?

  • NSPredicate aggregate function [SIZE] gives 'unsupported function expression' error

    - by jinglesthula
    iOS 4: I have entities in Core Data (using SQLite, which is a requirement) of: Request Response (which has a property personId) Revision Relationships are: Request <-- Revision Request <-- Response Revision <-- Response (e.g. each request may have many responses; each request/response pair may have many revisions) I'm trying to do a predicate to get all Responses with a given personId that have zero Revisions. Using: (personId == %d) && (Request.Revision[SIZE] == 0) in my predicate string gives me a runtime exception "Unsupported function expression Request.Revision[SIZE]" The documentation seems pretty sparse on aggregate functions, only noting that they exist, but with no syntax or examples. Not sure if it's my syntax or if the SIZE function really isn't supported in iOS.

  • How do I fix this warning in my mx:request tag?

    - by invertedSpear
    I'm running an HTTPService with the following request: <mx:request xmlns=""> <view>{myViewStack.selectedChild.name}</view> </mx:request> The idea being to pass which child is selected on the viewstack to the php page, and then get that back so I can run some logic based on which child of the viewstack was selected at the time. Everything seems to work, but I get the following warning: Data binding will not be able to detect assignments to "name". This doesn't seem to be causing any trouble, but I know warnings usually mean that I am not following the best practice. How can I fix this? I don't really need this item to be bound, because the name will never change at runtime, but I don't know how else to include it in the request.

  • RoR: Where is the "rails/info/properties" route defined?

    - by Dave Paroulek
    I'm running Rails 2.3.4. When I create a new rails project, the public/index.html file has a link named "About your application's environment" that points to "rails/info/properties". In dev mode, it gives a summary of the runtime environment. However, in production mode, it gives a 404 page cannot be found. Could someone point me in the direction of how and where the "rails/info/properties" route is configured? I'd just like to understand how it's set up.

  • Why is there "data" and "newtype" in Haskell?

    - by martingw
    To me it seems that a newtype definition is just a data definition that obeys some restrictions (only one constructor and such), and that due to these restrictions the runtime system can handle newtypes more efficiently. Ok, and the handling of pattern matching for undefined values is slightly different. But suppose Haskell would only knew data definitions, no newtypes: Couldn't the compiler find out for himself whether a given data definition obeys these restrictions, and automatically treat it more efficiently? I'm sure I'm missing out on something, these Haskell designers are so clever, there must be some deeper reason for this...

  • Unable to Access UILabel in UITableViewCell

    - by Nirmal
    I am having trouble in accessing which is in the UITableViewCell, that i have placed in my main .xib file. That Label is connected to IBOutlet servicesCell. And the Label inside the table view cell is connected through IBOutlet serviceLabel. At runtime i am not getting the text which i am assining to that label. Following is my sample code for that. static NSString *ServiceIdentifier = @"ServiceIdentifier"; UITableViewCell *cell1 = [tableView dequeueReusableCellWithIdentifier:ServiceIdentifier]; if(cell1 == nil) { [[NSBundle mainBundle] loadNibNamed:@"servicesCell" owner:self options:nil]; cell1 = servicesCell; } // label access serviceLabel = (UILabel *)[cell1 viewWithTag:1]; serviceLabel.numberOfLines = 3; serviceLabel.lineBreakMode = UILineBreakModeWordWrap; [serviceLabel setTextAlignment:UITextAlignmentLeft]; [serviceLabel setText:@"Testing String"]; Anyone have any idea then please help..

  • Access variable value using string representing variable's name

    - by Paul Ridgway
    Hello everyone, If the title was not clear, I will try to clarify what I am asking: Imagine I have a variable called counter, I know I can see its current value by doing something like: std::cout << counter << std::endl; However, assume I have lots of variables and I don't know which I'm going to want to look at until runtime. Does anyone know a way I can fetch the value of a variable by using its name, for example: std::cout << valueOf("counter") << std::endl; I feel being able to do this might make debugging large complex projects easier. Thanks in advance for your time.
