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. 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. You can rate examples to help us improve the quality of examples. These are the top rated real world C++ (Cpp) examples of CStatic::GetWindowText extracted from open source projects. However, you have to pass the whole destination buffer length (*including* the terminating NUL) to GetWindowText() as third parameter. C++ (Cpp) CStatic::GetWindowText - 3 examples found.
Note that the length value returned by GetWindowTextLength() excludes the terminating NUL. Str.resize(len) // make enough room in string For instance, // Set ip address to IPAddressCtrl CString csIpAddress '125.0.0. You can use SetWindowText () to set ip address in string to IPaddressCtrl. Something like this: int len = GetWindowTextLength(hwnd) This is in extension to my previous post. 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.
