C / C++ / MFC

Thanks for reply. Somehow I did not get the message across and the main question is getting muddled by stuff I am not so concerned about. The bottom line - which I actually just wanted someone to confirm - is that casting pointers from integer to double is a stupid idea. Thanks Case closed

The code is correct C++, except that this header file will only compile if included after Core, as it is in Eigenvalues: #ifndef EIGEN_EIGENVALUES_MODULE_H #define EIGEN_EIGENVALUES_MODULE_H #include "Core" ... #include "src/Eigenvalues/HessenbergDecomposition.h" src/Eigenvalues/HessenbergDecomposition.h is not supposed to be included directly. What is the cpp file that you're trying to compile?

Lots and lots of things in C++ (and C for that matter) can lead to undefined behavior if preconditions are not met. Signed integer arithmetic is just one of many. If you're programming in this language, you should be used to dealing with narrow contracts. So, no, they shouldn't be avoided. Deal with them depending on the situation, in many cases an assert will suffice. Pretending it's not a problem is fatal. (and no, gcc isn't the only compiler that assumes that naive signed overflow checks are always false)

I am canning this routine as the vector may end up being modified. Thx for the input.

You are welcome. Don't become discouraged, maybe rounding made things more complex in your case. THESE PEOPLE REALLY BOTHER ME!! How can they know what you should do without knowing what you want done?!?! -- C++ FQA Lite

Well that seems to be your answer.

You can use the wide char versions of atof()[^] or strtod()[^]. If the string does not begin with the numeric value (spaces are ignored), you must parse the string and pass a pointer to the value's offset.

Run "ipconfig /all" at the command prompt. Look at the results, there should be data given about each NIC card on YOUR machine. Look at the line that says "IP Address.......xxx.xxx.xxx.xxx" (there may be several). Make a list of these IP addresses. If "86.57.91.237" is not in that list, then you can not bind to it. Meaning it is not an IP address associated with a NIC on your computer.

atof() is part of the standard C library that uses the general 'C' locale by default while stringstream is C++ which uses the current system locale by default. You can use the setlocale()[^] function to change the locale for the standard C library functions (pass an empty string to use the environment's default locale).

It doesn't work because it is wrong. Quote: std::vector::iterator* it= myVec[i]; You are trying to assign a value (not an address) to an iterator. Please note, even std::vector::iterator* it= &myVec[i]; Would NOT WORK, because iterators are not exactly pointers. THESE PEOPLE REALLY BOTHER ME!!

Thank you Richard, deleteing CPrintInfo object is excluded, the destructor is the only place where I explicity delete this object ... I have to dig in ...

As the other reply stated, a full error message would be handy. Just a thought, you're definitely linking against a static library built for ARM as well ?

Since both rely totally on the .NET framework I do not think that is correct. If you do not want to rely on .NET then C++ (with or without MFC) is your only real choice.

The message is telling you what is wrong, you need to investigate why it is happening. See http://msdn.microsoft.com/en-gb/library/windows/desktop/bb759846(v=vs.85).aspx[^].
