.NET Forum / Languages / Managed C++ / October 2007trim heading and trailing space
Hello everyone, I think in built-in C/C++ functions, there is no direct function call to trim heading and trailing space characters, right? So, we have to implement it manually by iterating the string to check character one by one. Support not using MFC. thanks in advance, George >I think in built-in C/C++ functions, there is no direct function call to >trim heading and trailing space characters, right?

George, You're posing in a .Net group, so if you're using String ^, there is a Trim method already. If you're using native C++ using std:string, you might want to have a look at the Boost library facilities which I believe have trim facilities (http://www.boost.org/doc/html/string_algo/usage.html#id1638126) MFC's CString has its own Trim method built-in. Dave Thanks Dave, I think there is no built-in trim functions in even STL string.

There's an article on CodeProject too - http://www.codeproject.com/vcpp/stl/stdstringtrim.asp Dave Hi Dave, It is implemented by find_first_not_of and find_last_not_of of STL string, no built-in functions. regards, George > >I think there is no built-in trim functions in even STL string.

Dave Thanks Dave, I think there is no built-in trim function and the method described in CodeProject seems to be the best way. regards, George > >It is implemented by find_first_not_of and find_last_not_of of STL string, > >no built-in functions. > > Yes, that's what the CodeProject article uses. > > Dave Free MagazinesGet these publications absolutely FREE for up to 12 months.
