Background I am working on a phonetic converter program which converts english text into equivalant regional language text. Regional languages will have more characters than english letters and regional language fonts uses almost all positions (1-255) in a font. My program supports different fonts and I have created a font class which...

I've got a bug from one of our customers and believe that the problem lies with MSVCR80.DLL v8.0.50727.3053 - a version which I cannot find for download anywhere, however a google search turns up plenty of other crash reports. Latest version on my system (and others here) is 8.0.50727.1433 and the Microsoft Visual C++ 2005 SP1 Redistrib...
I'm just starting to learn C++ so you'll have to bear with my ignorance. Is there a way to to declare functions such that they can be referenced without being written before the function that uses them. I'm working with one cpp file (not my decision) and my functions call themselves so there is not really a proper order to place them in....
In GCC this code won't compile, because T gets shadowed, however in VS2005 it compiles with no warnings, so what are the assumptions VS compiler is making? template<typename T> class Foo { template<typename T> void Bar(const T& bar) { ... } }; ...
When comparing enums that come from different sources such as those of the following code GCC emits warnings. Is there a way to avoid these warnings without c-style casts? struct Enumerator { enum { VALUE = 5 }; }; template<int V> struct TemplatedEnumerator { enum { VALUE = V }; }; if(Enumerator::VALUE == TemplatedEnumerator<5...
Is it possible to have variable size (owner draw) items in the Win32 ListView, if yes, how? ...
Is it always necessary to allocate memory from the heap to facilitate dynamic polymorphism? All the examples i've come across so far point to the same. Dynamic memory allocation is usually avoided in real-time-programming.So,is there any disadvantage of using the stack for dynamic polymorphism as shown in the code below. class Base { ...
Well as the topic says, I want to know if there is a tool or a tutorial that can help me access IE, get in a certain URL, do some action on that website. So I would have a program to do that for me instead of doing it myself every time. ...

I want to suppress specific warnings from g++. I'm aware of the -Wno-XXX flag, but I'm looking for something more specific. I want some of the warnings in -Weffc++, but not all of them. Something like what you can do with lint - disable specific messages. Is there a built in way in gcc to do this? Do I have to write a wrapper script? ...
Hi! What do you think is best practice when creating public header files in C++? Should header files contain no, brief or massive documentation? I've seen everything from almost no documentation (relying on some external documentation) to large specifications of invariants, valid parameters, return values etc. I'm not sure exactly wha...
I have to implement a set of 60 functions, according to the predefined signatures. They must be global functions, and not some class's member functions. When I implement them, I use a set of nicely done classes provided by 3rd party. My implementation of most functions is quite short, about 5-10 lines, and deals mostly with different ac...
I am creating a game using Allegro/C++. The game is almost done and now, I want to create a map editor. The game contains numerous classes and their number will vary depending on the number of objects the map requires. I was thinking of creating a separate structure to hold level data and store it as a map. The problem is that the size v...
Hi all, I am a complete newbie to C++ so bear with me ;-) I have developed a console ATL application and want to trap the close?, exit?, terminate? event so that I can close log files and perform a general cleanup on exit. How can I trap the 'terminate' event that would result from someone ending the .exe in the task manager? Appreci...

I have several functions in my program that look like this: void foo(int x, int y) Now I want my program to take a string that looks like: foo(3, 5) And execute the corresponding function. What's the most straightforward way to implement this? When I say straightforward, I mean reasonably extensible and elegant, but it shouldn't t...
