I've learned in College that you always have to free your unused Objects but not how you actually do it. For example structuring your code right and so on. Are there any general rules on how to handle pointers in C++? I'm currently not allowed to use boost. I have to stick to pure c++ because the framework I'm using forbids any use of...
Let's say I have a list of server names stored in a vector, and I would like to contact them one at a time until one has successfully responded. I was thinking about using STL's find_if algorithm in the following way: find_if(serverNames.begin(), serverNames.end(), ContactServer()); Where ContactServer is a predicate function object. ...
Hi, We currently maintain a suit of MFC applications that are fairly well designed, however the user interface is beginning to look tired and a lot of the code is in need quite a bit of refactoring to tidy up some duplication and/or performance problems. We make use of quite a few custom controls that handle all their own drawing (all ...
I have to develop an application which parses a log file and sends specific data to a server. It has to run on both Linux and Windows. The problem appears when I want to test the log rolling system (which appends .1 to the name of the creates a new one with the same name). On Windows (haven't tested yet on Linux) I can't rename a file ...
I am about to reenter the MFC world after years away for a new job. What resources to people recommend for refreshing the memory? I have been doing mainly C# recently. Also any MFC centric websites or blogs that people recommend? ...
Basically I want tools which generate function call graph, dependency graph etc. ...
Most of my C/C++ development involves monolithic module files and absolutely no classes whatsoever, so usually when I need to make a DLL with accessible functions I just export them using the standard __declspec(dllexport) directive. Then access them either dynamically via LoadLibrary() or at compile time with a header and lib file. H...
I've been writing C and C++ code for almost twenty years, but there's one aspect of these languages that I've never really understood. I've obviously used regular casts (i.e. MyClass *m = (MyClass *)ptr; all over the place, but there seem to be two other types of casts, and I don't know the difference. What's the difference between th...
We often hear/read that one should avoid dynamic casting. I was wondering what would be 'good use' examples of it, according to you? Edit: @Sam: yes, I'm aware of that other thread: it is indeed when reading one of the first answers there that I asked my question! ...
We would like to have user defined formulas in our c++ program. e.g. The value v = x + ( y - (z - 2)) / 2. Later in the program the user would define x,y and z -> the program should return the result of the calculation. Somewhen later the formula may get changed, so the next time the program should parse the formula and add the new valu...
For whatever reason, our company has a coding guideline that states: Each class shall have it's own header and implementation file. So if we wrote a class called MyString we would need an associated MyStringh.h & MyString.cxx. Does anyone else do this? Has anyone seen any compiling performance repercussions as a result? Does 5000 cl...
I've been looking for a tool to extract exception information from a C++ program. The most wanted feature I'm looking for: I want to know all the exceptions that can be thrown from a function (which would include all the function that is called from that function recursively). I've always thought that documenting errors and exceptions i...
I'm trying to learn C. As a C# developer, my IDE is Visual Studio. I've heard this is a good environment for C/C++ development. However, it seems no matter what little thing I try to do, intuition fails me. Can someone give good resources for how to either: learn the ins and out of C in Visual Studio recommend a better C IDE + compiler...
I work a lot with network and serial communications software, so it is often necessary for me to have code to display or log hex dumps of data packets. Every time I do this, I write yet another hex-dump routine from scratch. I'm about to do so again, but figured I'd ask here: Is there any good free hex dump code for C++ out there some...
Maybe this is a dumb question, but is there any way to convert a boolean value to a string such that 1 turns to "true" and 0 turns to "false"? I could just use an if statement, but it would be nice to know if there is a way to do that with the language or standard libraries. Plus, I'm a pedant. :) ...
You have multiple network adapters. Bind a UDP socket to an local port, without specifying an address. Receive packets on one of the adapters. How do you get the local ip address of the adapter which received the packet? The question is, "What is the ip address from the receiver adapter?" not the address from the sender which we get ...
In my browsings amongst the Internet, I came across this post, which includes this "(Well written) C++ goes to great lengths to make stack automatic objects work "just like" primitives, as reflected in Stroustrup's advice to "do as the ints do". This requires a much greater adherence to the principles of Object Oriented ...
I remember first learning about vectors in the STL and after some time, I wanted to use a vector of bools for one of my projects. After seeing some strange behavior and doing some research, I learned that a vector of bools is not really a vector of bools. Anyone out there have any other common pitfalls to avoid in C++? ...
I want to create a simple http proxy server that does some very basic processing on the http headers (i.e. if header x == y, do z). The server may need to support hundreds of users. I can write the server in C# (pretty easy) or c++ (much harder). However, would a C# version have as good of performance as a C++ version? If not, would ...
