Edited again because it originally wasn't clear that I'm trying to initialize the arrays at compile time, not at run time... I've got the following reduced testcase: typedef struct TestStruct { int length; int values[]; }; TestStruct t = {3, {0, 1, 2}}; TestStruct t2 = {4, {0, 1, 2, 3}}; int main() { return(0); } This...
I've already done some little things using Visual Basic and some nice things with eMbedded Visual Basic, but now I want to go on the scripting way, then I want to know if Linux, BeOS and other OSes browsers will support VBScript pages. ...
Hi, I have a network software which uses UDP to communicate with other instances of the same program. For different reasons, I must use UDP here. I recently had problems sending huge ammounts of data over UDP and had to implement a fragmentation system to split my messages into small data chunks. So far, it worked well but I now encoun...
TiddlyWiki is a great idea, brilliantly implemented. I'm using it as a portable personal "knowledge manager," and these are the prize virtues: It travels on my USB flash memory stick and runs on any computer, regardless of operating system No software installation is needed on the computer (TiddlyWiki merely uses the Internet browser)...
I want a portable C++ IDE for general development, and too to develop basic Windows GUI applications. In my research, I've found this (with latest version date): CodeLite IDE (2010-04-02) Ultimate++ (2010-03-16) Qt Creator (2010-02-01) NetBeans (2009-12-10) Code::Blocks (2008-02-28) Bloodshed Dev-C++ (2005-02-22) But I don't know if...
If a compiler doesn't "support" RTTI, does that mean that the compiler can not handle class hierarchies that have virtual functions in them? Or have I been misunderstanding the literature about how RTTI isn't portable, and the issues lie elsewhere? Thank you all for your comments! ...
Please refer to my previous question here: Link Here Will this project type be useful for installing the necesary database on a servers machine? ...
I’m looking into multithreading, and GCD seems like a much better option than manually writing a solution using pthread.h and pthreads-win32. However, although it looks like libdispatch is either working on, or soon going to be working on, most newer POSIX-compatible systems… I have to ask, what about Windows? What are the chances of lib...
I came up with this as a quick solution to a debugging problem - I have the pointer variable and its type, I know it points to an array of objects allocated on the heap, but I don't know how many. So I wrote this function to look at the cookie that stores the number of bytes when memory is allocated on the heap. template< typename T > i...
As the title suggests — can I be reasonably sure that mktemp will exist on any unix-y operating system I'm likely to encounter? ...
I have an algorithm that uses the following OpenSSL calls: HMAC_update() / HMAC_final() // ripe160 EVP_CipherUpdate() / EVP_CipherFinal() // cbc_blowfish These algorithm take a unsigned char * into the "plain text". My input data is comes from a C++ std::string::c_str() which originate from a protocol buffer object as a encoded UTF-8 ...
FastCGI servers, for example, impose an execution time limit on PHP scripts which cannot be altered using set_time_limit() in PHP. IIS does this too I believe. I wrote an import script for a PHP application that works well under mod_php but fails under FastCGI (mod_fcgid) because the script is killed after a certain number of seconds. ...
Which features of regular expressions are standard, and which are idiosyncratic ? What should I do, and not do, if I want to use the same regex in different context, languages, platforms ? ...
I'm trying to have classes serialized using MS runtime and Mono runtime. While using MS runtime everything goes fine, but using Mono I give me some exception and program startup. The following exception are thrown: There was an error reflecting a type: System.TypeInitializationException (a class) There was an error reflecting a type: ...
Hi, in Java I think it is possible to cruise through jar files like they were not compressed. Is there some similar (and portable) thing in C/C++ ? I would like to import binary data into memory from a large (zipped or similar) file without decompressing to disk first and afterwards writing to disk in a compressed way. Maybe some tr...
I have a situation where I am trying to draw a semi-transparent rectangle over a background that is not using openGL and so I can not use blending. I decided to use polygon stippling for a 'screen door transparency' effect as recommended by some. It works fine on my machine and some others, but on some machines with slightly old Intel ...
How do I type a floating point infinity literal in python? I have heard inf = float('inf') is non portable. Thus, I have had the following recommended: inf = 1e400 Is either of these standard, or portable? What is best practice? ...
Hey, I'm creating a little GLUT application and need help with hiding/removing the console window. I am developing on windows and I already know of the various methods to hide the console window on a windows system, however is there no portable method of hiding it? Thanks... ...
I know how they work conceptually, but how are signals and slots implemented in the Qt framework? Qt Creator treats them as keywords, but are they simply a set of macros, or is a special pre-processor required before these source files can be compiled? In other words, if I use Qt's signal/slot features in my code, can I easily compile ...
I've created an ASP.NET solution on my computer. There is a business layer in the project, which uses Linq-To-Sql for Database operations. How can I open the same project on another computer? I am having problems, becuse of connection string or etc. ...
