I see that Visual Studio 2008 and later now start off a new solution with the Character Set set to Unicode. My old C++ code deals with only English ASCII text and is full of: Literal strings like "Hello World" char type char * pointers to allocated C strings STL string type Conversions from STL string to C string and vice versa using S...
Hello. I use inline assembly massively in a project where I need to call functions with an unknown number of arguments at compile time and while I manage myself to get it to work, sometimes, in linux (in windows I don't recall having that problem) strange things like this happen: If I have something like for(int i = 1; i >= 0; i--) ...
Hello, I am developing C++ in NetBeans 6.7.1. When I press CTRL + space for autocomplete there is shown only method's signature. I am using JavaDoc for commenting my code but NetBeans doesn't show it. I have installed Doxygen plugin but it is only for generating complete documentation. Is there any way how to force the IDE to show sign...

Hi, I have a big app using many static libs, which is platform independant and deployed under Windows and Linux. All static libs and the main() itself are compiled with two defines: -DVERSION=1.0.0 -DBUILD_DATE=00.00.0000 These defines are used by macros inside each static lib and inside the main to store the current lib version ins...
Hello, I get to the very last linking command (the actual executable is being linked) but i get a BUNCH of undefined symbols (and they're in cpp and look so scary to me, a simple c programmer) --its probably something simple but i cant get what im supposed to put as linker (its using gcc here...? is that appropriate? g++ told me too ma...

I am updating a GUI of a Win32 Application in white text on black background. Thats simple for my content. But how can i change also the color of my child windows (Titlebar, Scrollbar etc.). i Know there is WM_CTLCOLORDLG to set the color of Dialogs. I also know there is WM_NCPAINT, but that would leave all painting (i.e of Scrollbars) ...
CFUserNotificationDisplayAlert and CFUserNotificationDisplayNotice creates a non-modal window and this is bad because it could bring your application UI in a very undesired state if you select the original application window (the message box is hidden but the applicaton does not respond). The old SystemAlert was modal but this one doesn...
I have a templated function that operates on a template-type variable, and if the value is less than 0, sets it to 0. This works fine, but when my templated type is unsigned, I get a warning about how the comparison is always false. This obviously makes sense, but since its templated, I'd like it to be geenric for all data types (signe...
I have a method that has a few pointers as parameters. This method can be called with either named pointers from the callee or dynamically create a pointer to a new object and pass it in as an argument directly as the method is being called. myClass *myPtr = new myClass(...); myMethod(myPtr); Verus myMethod(new myClass(...)); The ...
Hi, I have a c++ client which needs to send a file to a c++ server. I'm splitting the file to chunks of PACKET_SIZE (=1024) bytes and send them over a TCP socket. At the server side I read at most PACKET_SIZE bytes to a buffer. When the client sends files which are less than PACKET_SIZE, the server receives more bytes than sent. Even wh...
I'm getting console input from the user and want to encode it to UTF-8. My understanding is C++ does not have a standard encoding for input streams, and that it instead depends on the compiler, the runtime environment, localization, and what not. How can I determine the input encoding? ...
Hi all, I have some C++ code where I need to implement cache replacement using LRU technique. So far I know two methods to implement LRU cache replacement: Using timeStamp for each time the cached data is accessed and finally comparing the timeStamps at time of replacement. Using a stack of cached items and moving them to the top if ...
I would like to get started developing native (C/C++) OpenGL ES 2.0 applications for Windows Mobile (version 5 or later, any version would do, really). I do however have trouble finding appropriate headers and libraries. What I am looking for is a OpenGL ES 2.0 SDK for Windows Mobile, or an SDK which contains the appropriate headers and...

I am writing an arduino library to post http request on web. I am using the String class from http://arduino.cc/en/Tutorial/TextString My code is behaving strangely when I am referring to my defined string objects after a function call.

I want to use the STL's Map container to lookup a pointer by using binary data as a key so I wrote this custom function object: struct my_cmp { bool operator() (unsigned char * const &a, unsigned char * const &b) { return (memcmp(a,b,4)<0) ? true : false; } }; And using it like this: map<unsigned char *, void *,...
Hi! is it possible/ok to return a const reference even if the value the function returns is a local variable of this function? i know that locals are not valid anymore once the function returns - but what if the function is inlined and the returned value is only used within the callers scope? then the locals of the function should be in...
I am wondering if you can : lock only a line or a single character in a file in linux and the rest of the file should remain accessible for other processes?
