• The C++ 'new' keyword and C

  - by Florian

  In a C header file of a library I'm using one of the variables is named 'new'. Unfortunately, I'm using this library in a C++ project and the occurence of 'new' as a variable names freaks out the compiler. I'm already using extern "C" { #include<... }, but that doesn't seem to help in this respect. Do I have to aks the library developer to change the name of that variable even though from his perspective, as a C developer, the code is absolutely fine, as 'new' is not a C keyword?

• Problem with images in upload directory after upgrading WordPress to 3.0

  - by Volmar

  I've developed a WordPress plugin and it wordked well from WP 2.0 and up to WP 3.0rc1 (haven't tried rc2) but now with rc3 and milestone 3.0 a strange and irritating error appeared. If you check out my demo page you will se that none of the cover-images is working. they are in the same place as before but they can not be hotlinked or show up when i enter the correct url. if i move the img-directory from /wp-content/uploads/my-record-collection/ to /wp-content/uploads/ the images show up if i enter the url, but not if i move it back inside my "my-record-collection"-folder. anyone know what change in rc3(or maybe rc2) that made this bug appear and what can be done to fix it?

• How can I update the version of an APK which I did not create myself

  - by sylvanaar

  I am new to Android development. I am using a x-platform development tool which builds and signs the APK for me. This tool has a bug and it does not generate APK's with the version number I specify, all APK's generated are version 1.0. I would like to unpack the APK, edit the version number, and then resign and repackage it. It was signed using my keystore originally, so I have the keys needed to sign it again. How can this be done?

• How many instructions to access pointer in C?

  - by Derek

  Hi All, I am trying to figure out how many clock cycles or total instructions it takes to access a pointer in C. I dont think I know how to figure out for example, p-x = d-a + f-b i would assume two loads per pointer, just guessing that there would be a load for the pointer, and a load for the value. So in this operations, the pointer resolution would be a much larger factor than the actual addition, as far as trying to speed this code up, right? This may depend on the compiler and architecture implemented, but am I on the right track? I have seen some code where each value used in say, 3 additions, came from a f2->sum = p1->p2->p3->x + p1->p2->p3->a + p1->p2->p3->m type of structure, and I am trying to define how bad this is

• from ggplot2 to OOo workflow?

  - by Andreas

  This is not really a programming question, but I try here none the less. I once used latex for my reports. But the people I work with needs to make small edits and do not have latex skillz. Openoffice is then the way to go. But saving ggplot images with dpi 100 makes for really ugly graphs. dpi = 600 is a no go (e.g. huge legend). So what to do? I currently save (still via ggsave) to eps - which openoffice can import. But performance is not good at all. Googling I found a bug for the poor eps performance in OOo, and also talk about a non-implemented svg feature. But none helps me right now. If you work with ggplot2 and OOo - What do you do? I have been unsuccesfull with pdf conversion for some reason.

• How can I display a hidden view in Interface Builder which is on a unattached monitor?

  - by Brennan

  I am using Interface Builder to work on NIBs and one of the NIBs must have a view on my external monitor which is not attached because I cannot see it on my MacBook. I have had this problem with editing iPad NIBs which I work on with my larger external monitor. For some reason Interface Builder is not detecting that there is now just one screen and not pulling this view onto this monitor. There has to be a way to get this back into the visible space so that I can work on it. I have tried double clicking on the view icon in the organizer which normally brings the view forward but it is not coming into view. What can I do? Is this really a bug that has been around this whole time?

• Resources for looking up differences in rendering behavior between web-browsers and browser bugs

  - by ICodeForCoffee

  I recently encountered a printing issue in Firefox that eventually turned out to be a problem with the fieldset tag we wrapped the entire page in. (Bugzilla: Bug 471015) All browsers have their own rendering quirks and issues, but it can be very hard to know what's causing different behaviors. Sure, you can Google, but that's often taking a shot in the dark about what you think is causing the problem. It also doesn't stop you from having to sort through multiple complains about the same behavior before you find someone who has the issue your looking for. Are there any websites out there that let you search for rendering behavior issues by browser version, browser function, css tag, or html tag? I've seen this SO Question, Wanted: Resource for documented Cross-Browser differences, but I'd like to find something more detailed that includes browser bugs.

• Are there any C++ tools that detect misuse of static_cast, dynamic_cast, and reinterpret_cast?

  - by chrisp451

  The answers to the following question describe the recommended usage of static_cast, dynamic_cast, and reinterpret_cast in C++: http://stackoverflow.com/questions/332030/when-should-static-cast-dynamic-cast-and-reinterpret-cast-be-used Do you know of any tools that can be used to detect misuse of these kinds of cast? Would a static analysis tool like PC-Lint or Coverity Static Analysis do this? The particular case that prompted this question was the inappropriate use of static_cast to downcast a pointer, which the compiler does not warn about. I'd like to detect this case using a tool, and not assume that developers will never make this mistake.

• vector<vector<largeObject>> vs. vector<vector<largeObject>*> in c++

  - by Leif Andersen

  Obviously it will vary depending on the compiler you use, but I'm curious as to the performance issues when doing vector<vector<largeObject>> vs. vector<vector<largeObject>*>, especially in c++. In specific: let's say that you have the outer vector full, and you want to start inserting elements into first inner vector. How will that be stored in memory if the outer vector is just storing pointers, as apposed to storing the whole inner vector. Will the whole outer vector have to be moved to gain more space, or will the inner vector be moved (assuming that space wasn't pre-allocated), causing problems with the outer vector? Thank you

• how to create a new variant in bjam

  - by steve jaffe

  I've tried reading the documentation but it is rather impenetrable so I'm hoping someone may have a simple answer. I want to define a new 'variant', based on 'debug', which just adds some macro definitions to the compiler command line, eg "-DSOMEMACRO". I think I may be able to do this as a "sub-variant" of debug, or else just define a new variant copying 'debug', but I'm not even sure where to do this. It looks like feature.jam in $BOOST_BUILD_DIR/build may be the place. Perhaps what I really want is simply a new 'feature' but it's still not clear to me exactly what I need to do and where, and I don't know if a 'feature' allows me to direct the build products to a different directory to the 'debug' build. Any suggestions will be appreciated. (In case you're wondering, I have to use bjam since it has been adopted as our corporate standard.)

• Declaring pointers; asterisk on the left or right of the space between the type and name?

  - by GenTiradentes

  I've seen mixed versions of this in a lot of code. (This applies to C and C++, by the way.) People seem to declare pointers in one of two ways, and I have no idea which one is correct, of if it even matters. The first way it to put the asterisk adjacent the type name, like so: someType* somePtr; The second way is to put the asterisk adjacent the name of the variable, like so: someType *somePtr; This has been driving me nuts for some time now. Is there any standard way of declaring pointers? Does it even matter how pointers are declared? I've used both declarations before, and I know that the compiler doesn't care which way it is. However, the fact that I've seen pointers declared in two different ways leads me to believe that there's a reason behind it. I'm curious if either method is more readable or logical in some way that I'm missing.

• Why C++ virtual function defined in header may not be compiled and linked in vtable?

  - by 0xDEAD BEEF

  Situation is following. I have shared library, which contains class definition - QueueClass : IClassInterface { virtual void LOL() { do some magic} } My shared library initialize class member QueueClass *globalMember = new QueueClass(); My share library export C function which returns pointer to globalMember - void * getGlobalMember(void) { return globalMember;} My application uses globalMember like this ((IClassInterface*)getGlobalMember())->LOL(); Now the very uber stuff - if i do not reference LOL from shared library, then LOL is not linked in and calling it from application raises exception. Reason - VTABLE contains nul in place of pointer to LOL() function. When i move LOL() definition from .h file to .cpp, suddenly it appears in VTABLE and everything works just great. What explains this behavior?! (gcc compiler + ARM architecture_)

• Newbie question: Creating a custom control

  - by Wild Thing

  Hi, I have an ASP.Net site, in which I am using a ListView with a Datapager. Apparently there is a bug with the Datapager, where it crashes if there is an empty ampersand (&) in the querystring. This is a known issue: https://connect.microsoft.com/VisualStudio/feedback/ViewFeedback.aspx?FeedbackID=357344&wa=wsignin1.0#tabs I see that there is a workaround given, but did not understand how to implement it. Can somebody point me in the right direction? Also, I see that this issue is marked as resolved. Any idea where I can find the updated version of this control? Wild Thing

• How well does Scala Perform Comapred to Java?

  - by Teja Kantamneni

  The Question actually says it all. The reason behind this question is I am about to start a small side project and want to do it in Scala. I am learning scala for the past one month and now I am comfortable working with it. The scala compiler itself is pretty slow (unless you use fsc). So how well does it perform on JVM? I previously worked on groovy and I had seen sometimes over performed than java. My Question is how well scala perform on JVM compared to Java. I know scala has some very good features(FP, dynamic lang, statically typed...) but end of the day we need the performance...

• About enumerations in Delphi and c++ in 64-bit environments

  - by sum1stolemyname

  I recently had to work around the different default sizes used for enumerations in Delphi and c++ since i have to use a c++ dll from a delphi application. On function call returns an array of structs (or records in delphi), the first element of which is an enum. To make this work, I use packed records (or aligned(1)-structs). However, since delphi selects the size of an enum-variable dynamically by default and uses the smallest datatype possible (it was a byte in my case), but C++ uses an int for enums, my data was not interpreted correctly. Delphi offers a compiler switch to work around this, so the declaration of the enum becomes {$Z4} TTypeofLight = ( V3d_AMBIENT, V3d_DIRECTIONAL, V3d_POSITIONAL, V3d_SPOT ); {$Z1} My Questions are: What will become of my structs when they are compiled on/for a 64-bit environment? Does the default c++ integer grow to 8 Bytes? Are there other memory alignment / data type size modifications (other than pointers)?

• Understanding Ruby Enumerable#map (with more complex blocks)

  - by mstksg

  Let's say I have a function def odd_or_even n if n%2 == 0 return :even else return :odd end end And I had a simple enumerable array simple = [1,2,3,4,5] And I ran it through map, with my function, using a do-end block: simple.map do |n| odd_or_even(n) end # => [:odd,:even,:odd,:even,:odd] How could I do this without, say, defining the function in the first place? For example, # does not work simple.map do |n| if n%2 == 0 return :even else return :odd end end # Desired result: # => [:odd,:even,:odd,:even,:odd] is not valid ruby, and the compiler gets mad at me for even thinking about it. But how would I implement an equivalent sort of thing, that works?

• addObjectsFromArray

  - by derek.lo

  I have a question about memory management when using the addObjectsFromArray method. Basically, I have 2 arrays defined in the appDelegate. I need these 2 arrays for the duration of my application's runtime. I therefore release them in my appDelegate's dealloc method. When I go to use these two arrays in a class, I want one array to store the values from the other, so that the other can have it's contents removed, but still stick around for use. Something like this: [appDelegate.arrayTwo addObjectsFromArray:appDelegate.arrayOne]; [appDelegate.arrayOne removeAllObjects]; I'm getting the compiler error: EXC_BAD_ACCESS because of a pointer issue? retaining issue? Any help would be greatly appreciated! Thanks

• Installing a condition handler in Common Lisp

  - by Paul Nathan

  The HTTP library Drakma on CLISP generates an error USOCKET:UNSUPPORTED due to a bug in Drakma+CLISP. However, it turns out that the CONTINUE restart seems to work fine. Therefore, I spent some time with CLtL and other references trying to determine how to write a restart handler. (defun http-request (url param) (handler-bind ((USOCKET:UNSUPPORTED #'(lambda (x) (invoke-restart 'continue))))) (drakma:http-request url :method :post :parameters param)) According to my best understanding, the above code should trap the error USOCKET:UNSUPPORTED. It doesn't; it seems to ignore the error binder. How do I fix this?

• Has anyone noticed that a WPF file dialog will pass through a click to the UI when double clicking t

  - by Ben

  I have some buttons on my WPF UI and I also need to choose files from time to time. I kept noticing strange problems where when I double-click an item in the file dialog, a button on the main UI would also get clicked. After experimenting, it seems that if you line up an item in the file dialog with a button behind it on the main UI and double click to select the file, it will single-click the button behind it as well. Has anyone else noticed this, or is it just a freak bug with the way I have my UI laid out?

• Network Security and Encryption explained in laymen terms

  - by Ehrann Mehdan

  Although I might pretend very well that I known a thing about networks or security and it might help me pass an interview, or fix a bug, I don't really feel I'm fooling anyone. I'm looking for a laymen terms explanation of nowadays network security concepts and solutions. The information is scattered around and I didn't find a resource for "dummies" like me (e.g experienced Java developers that can speak the jargon but have no real clue what it means) Topics I have a weak notion about and want to understand better as a Java developer PGP Public / Private keys RSA / DES SSL and 2 way SSL (keystore / trustore) Protecting against Man in the middle fraud Digital Signature and Certificates Is there a resource out there that really explains it in a way that doesn't require a Cisco certificate / Linux lingo / know what is subnet masking or other plumbing skills?

• Why can't QFile read from the "~" directory?

  - by hurikhan77

  I've tried the following short example to find out about a bug in a bigger program I am working on. It looks like QFile doesn't support unix (or the shell's) notation for the home directory: #include <QFile> #include <QDebug> int main() { QFile f("~/.vimrc"); if (f.open(QIODevice::ReadOnly)) { qDebug() << f.readAll(); f.close(); } else { qDebug() << f.error(); } } As soon as I replace the "~" with my real home directory path, it works. Is there an easy workaround - some setting to enable? Or do I have to go the "ugly" way and ask QDir for the home directory of the current user and prepend that manually to each path?

• Is it valid syntax to have ordered and unordered lists in sequence in markdown?

  - by nfm

  I just wrote some markdown and it doesn't seem to render correctly. Is it legal syntax to have an ordered list, followed by newlines, then followed by an unordered list? Or is this a bug in bluecloth? For example: 1. One 2. Two 3. Three * Apple * Banana * Carrot Bluecloth creates a single <ul> and nests apple, banana and carrot as <li>'s under it. Stackoverflow's markdown parser does this too. Am I just doing it wrong? Surely this is a common usage case...

• Visual C++ 2010 solution-wide macros with parameters

  - by OregonGhost

  I'm trying to compile some source code with Visual C++ 2010 Express. The code was written for GCC, and contains attributes like this: struct something { ... } __attribute__((packed)); Since this is not standard C++ syntax, Visual C++ doesn't recognize it. With this macro prior to the struct declaration, it works fine: #define __attribute__(p) But I don't want to alter the files. I created a new property sheet (GccCompat), and went to Preprocessor Definitions, and added the macro, like this: __attribute__(p) or like this: __attribute__(p)= But it doesn't work. It's simply not called. If I define just __attribute__ (without parameters) in the same location, the macro is correctly defined. Note that the command line that is generated looks fine (the macros with parameters are passed exactly the same as the ones without), but the compiler seems to ignore it. So, how can I globally define my macro with a parameter?
