I have a C++ application that embeds the Python interpreter. It calls PyImport_Import to load scripts. I need a way of getting any syntax errors as C strings. For example, if the script uses a undefined function, I would like an error saying something like 'Function xxx is undefined.' How would I do this? ...

Hi, I'm storing some classes with WideString parameters describing them (like name, description and some others). Now if I change all those WideStrings to simple "string" (I'm using alias actually so I have to change one line only), memory usage is about 5% bigger!! than previously... How is that possible, since each char of the string i...
Hello, Assume that there is an object, passed as an argument to a function. the argument name is "obj". can it be concatenated as followed? $(obj + " .className")...... OR $(obj + "[name='obj_name'])...... Thanks. ...
I have a library which needs to parse double numbers which always use a point '.' as decimal separator. Unfortunately for this case, strtod() respects the locale which might use a different separator and thus parsing can fail. I can't setlocale() - it isn't thread-safe. So I'm searching for a clean locale-independent strtod implementatio...
string::iterator it; for (it = str.begin(); it < str.end(); it++) cout << *it; cout << endl; Why not: for (int i = 0; i < str.size(); i++) cout << str[i]; cout << endl; It seems that string::iterator does not provide range check either. Why should we use string::iterator rather than index? Thanks. ...
void permute(string elems, int mid, int end) { static int count; if (mid == end) { cout << ++count << " : " << elems << endl; return ; } else { for (int i = mid; i <= end; i++) { swap(elems, mid, i); permute(elems, mid + 1, end); swap(elems, mid, i); } } ...
I have an MFC application in C++ that uses std::string and std::wstring, and frequently casts from one to the other, and a whole lot of other nonsense. I need to standardize everything to a single format, so I was wondering if I should go with CString or std::wstring. In the application, I'll need to generate strings from a string tabl...

I'm working through a Python 3 book and came across the string function isidentifier(). The text description is "s.isidentifier() : Returns True if s is non empty and is a valid identifier". I tested it in the Python Shell like this: >>> s = 'test' >>> s.isidentifier() True >>> 'blah'.isidentifier() True I would expect the 2nd state...
I have an enum: public enum Color { Red, Blue, Green, } Now if I read those colors as literal strings from an XML file, how can I convert it to the enum type Color. class TestClass { public Color testColor = Color.Red; } Now when setting that attribute by using a literal string like so, I get a very harsh warning f...
I am using strpos() to find the needle in the haystack. But, I want it to only find the needle with the same string length. E.g.: $mystring = '123/abc'; $findme = 'abc'; $pos = strpos($mystring, $findme); // THIS IS FINE $mystring = '123/abcdefghijk'; $findme = 'abc'; $pos = strpos($mystring, $findme); // THIS IS NOT FINE So, I...
I'm solving this K&R exercise: Write versions of the library functions strncpy , strncat , and strncmp , which operate on at most the first n characters of their argument strings. For example, strncpy(s,t,n) copies at most n characters of t to s . Full descriptions are in Appendix B. So i was wandering if there's a site that contains s...

The application is written in C# (.NET 3.5) and I would like to attach a method to key press e...
Do you know any solution for building string filters based on human input in PHP? E.g. foo and bar -zoo (like in search enginies) is converted to regex similar to this: .*(foo|bar).*^(zoo).*. I have found this class, but this is not exactly what I am looking for. ...
