My MFC application generates a C program. I need to incorporate a C compiler into it which can compile this code and indicate the lines of errors. Can someone suggest me a good OpenSource C Compiler which I could use? I am using Visual Studio .Net to develop my application Thanks in advance.

How can I emove an item in STL iterator without use the STL algorithm? I know we can use stl erase, find_if to remove items from a STL vector , but how can I do the same without using STL algorithm? vector<int> srcVector; vector<int> destVector; for (vector<int>::iterator itr = srcVector; itr != srcVector; itr++) { int i = (*itr);

Hi, I have a project that's supposed to create a program for a "Dating Service". The first part of the program is to read a textfile of profiles which include names, age, etc...into a string array, and be able to add,edit,remove to the textfile of profiles during runtime. What would be the most efficient way to do this to make it easiest as...

Hi Group, I've got a problem I couldn't find a good solution. I am working with scientific data files in netCDF format. One of the properties of netCDF data is that the actual type of data is only known at run time. Therefore a lot of template based trick isn't too useful. Considering datafile float x(3) 3.5, 2.5, 8.9 double y(3)...

Hi, I have a bit of code where I am relying on empty base member optimisation. The bit of code is below: template<typename Enum> struct EncodePrefix { template<Enum e> struct Apply

I would like to merge together several STL integer vectors using STL's merge() function. What is the best way to do this while avoiding unnecessary vector copying? Is the following a good approach? vector<vector<int> > data; // already filled up properly with integers vector<int> result; // temp space

A very simple example of something that acts quite odd: class TopClass { public: TopClass(){ } virtual ~TopClass(){ } virtual int myFunc() = 0; };

As we all know, iostreams cannot be assigned or copied. This gives me a problem: suppose we have class Foo { std::istream in; public: Foo::Foo(std::istream& in_) : in(in_.rdbuf()) {} }; This would not compile, as std::ios_base has a private copy constructor.

delete this; I have seen it used occasionally, and I would have a use for it. Is it allowed? Assuming, of course, that I do nothing to the object thereafter. Thanks, Mike.

I mean to write the DES Algorithm myself.

Hi there, I have some trouble using STL containers. I'm working on a multithreaded (pthread) application making heavy usage of STL containers. All accesses to containers are made in locked sections (using mutexes). But sometimes it happens that the application crashes on container operations. The 2 last crashes are : * calling push_back on...

I have read several messages on converting packed decimals (EBCDIC) in a C++ program, but they were all for AS400 systems. I am looking for a way to convert the packed decimals in a COBOL program that is on a MVS (z/OS) system in a C++ program. Anyone have any idea how to do this? Is there a header or class that will do this?? Thanks in...

My application was developed under Visual C++ 6.0, ATL, MFC & PlatformSDK Feb2003 (the last VC6 compatible version). I am wondering if PlatformSDK Feb2003 is compatible with Visual Studio.NET 2003? I am having major problems trying to port/build my application under Visual Studio.NET 2003 using the unmanaged/native C++ compiler. I was...

Okay, this if my first post so go easy on me plus I've only been using C for a couple of weeks. I'm working on a program currently that requires me to read data from a .dat file into a 2d array and then print out the contents of the 2d array to the screen. I wil also need to append data to the .dat file but mostly right now I'm worrying about...

Hi! The following program gcc returns error: class Z { int a; int b; };

EXECryptor Software Copy Protection and License Management System is updated to version 2.3.7 Added full Unicode support for serial numbers. Using Unicode registration names they are transformed in UTF-8 representation and then are treated by relevant same-name ANSI functions. As the representation of string that contains only latin...

I have a template class template <Class W> class WS At some point I have to use a STL list WS<W>objects so, I define #include <list>

I am about to pull my hair out! I have VS 2005 PRO and I am coding in C++ I have a console program that parses data and creates a text output. I need to use MSWords mailmerge to merge the text output and save the doc for emailing later. I have a macro in MSWord that merges the data from the textfile with the doc. I have looked everywhere...

Hello all, does any one know a scource code for a keylogger, invisible one and doesn't appear any where on the computer and send the log file via email? thanks in advance...

Does c++ pronounce c plus plus? Thanks.

Hello, Supposed sizeof(short) == 2 and sizeof(int) == 4 and argument passing in a stack. When doing: int i1; int i2; printf("%d %d", i1, i2); // OK. 2 arg of size 4

Hi, I'm a newbie. Can someone please explain to me what will happen if I use "delete this". Is it bad to use it? Thanks, Gaurav

fread hangs before reaching eof() Hi, I'm reading the datat from the file. I could read the data by fread but it hangs on last data. its juz before reaching eof(). The same file could read all the data in debug mode but could not read in executable mode. I'm using VS .net 2003 and VC++ 7.1

I want to enfore the implementation of the operator overloading eg class Interface_ { public: virtual void operator = (const Interface &other)=0; virtual void operator +=(const Interface &other)=0; } but in the sub class
