From Dr. Dobbs: Concepts were to have been the central new feature in C++0x Even after cutting "concepts," the next C++ standard may be delayed. Sadly, there will be no C++0x (unless you count the minor corrections in C++03). We must wait for C++1x, and hope that 'x' will be a low digit. There is hope because C++1x...
I have to read a text file which is Unicode with UTF-8 encoding and have to write this data to another text file. The file has tab-separated data in lines. My reading code is C++ code without unicode support. What I am doing is reading the file line-by-line in a string/char* and putting that string as-is to the destination file. I can'...

I have a VCL gui developed in Codegear.

Now because I only want some of the child components to be drop targets (not the whole form), I only have the DragEnter method return S_O...
I understand you can use the inline keyword or just put a method in a class declaration ala short ctor or a getter method, but does the compiler make the final decision on when to inline my methods? For instance: inline void Foo::vLongBar() { //several function calls and lines of code } Will the compiler ignore my inline declarati...

I'm trying to compile an unspecified piece of software, and I'm getting errors in the standard headers such as stdio.h. The errors are mostly undeclared identifiers such as _In_. IntelliSense finds their definitions just fine. In what general direction should I look for the cause of this? Added: For example, in one cpp file stdio.h is t...
I'm downloading a file using QNetworkAccessManager::get but unlike QHttp::get there's no built-in way to directly write the response to a different QIODevice. The easiest way would be to do something like this: QIODevice* device; QNetworkReply* reply = manager.get(url); connect(reply, SIGNAL(readyRead()), this, SLOT(newData())); and...

Hello, I have a function that allocates two variables on the heap and returns them to the caller. Something like this: void Create1(Obj** obj1, Obj** obj2) { *obj1 = new Obj; *obj2 = new Obj; } Usually, in similar cases, when I have a function with one variable I use the "source" trick with auto_ptr: auto_ptr<Obj> Create2() ...
Hi, I'm a little confused as to how the model should 'work' in my basic C++ implementation, or rather how the data from say the database backend should be encapsulated/worked with. My thoughts at the moment are for a model with for example a static findById() method, which would return an instance of that same model, which would then r...

For example: QFile file(resource_name); file.open(QIODevice::ReadOnly); uchar* ptr = file.map(0, file.size()); When I try this, ptr == 0, indicating an error. It works fine if I try to map a regular file. I am running qt on linux, which supports QFile::Map. ...
