![]() ![]() The respective string types are then respectively ( TCHAR and LPCTSTR or WCHAR and LPCWSTR or CHAR and LPCSTR). ![]() On windows, you can compile to MBCS or ASCII. Set the resulting string as the text of your TextBox.ĭepending on your preferences regarding multi character strings and globalization, you might decide to stick to the ASCII versions at first.Convert the vector back to a string, which is the inverse of your split function (Hint: std::ostringstream).Convert string to a std::vector, using your split function (see the other question for how to do that).So, all you have to do is a sort of round trip: How to turn that string into a list/vector of strings, with words being the elements of that list/vector is in fact an STL problem.īasically, you are looking for the C++ equivalent of the C# function String.Split().Īnd there is already a good question and answer for that, here: While not the only way, you found a solution to transfer a string back and forth to your edit box. Now, since your C++ code is already Windows-specific, that should not be a problem.Īnd, anyway, IMO the standard should be fixed to allow something like overwriting the terminating NUL with another NUL a valid well-defined operation.Your problem is not a winapi problem. However, it seems to work just fine in Visual Studio (tested on both 20). However, note that overwriting the NUL terminator in STL strings with another NUL terminator seems to be "undefined behavior", at least according to this discussion on Stack"" This approach is more efficient than having a separate std::vector for buffer allocation, with a separate dynamic memory allocation, and then a deep-copy into the std::wstring. However, you have to pass the whole destination buffer length (*including* the terminating NUL) to GetWindowText() as third parameter. Note that the length value returned by GetWindowTextLength() excludes the terminating NUL. Str.resize(len) // make enough room in string Something like this: int len = GetWindowTextLength(hwnd) Then how are you supposed to get any window text ?Īn option would be to make enough room inside the string for storing text in it. ![]()
