CString str("Hello World"); LPTSTR lpBuffer = str.GetBuffer(0); //do something with lpBuffer str.ReleaseBufferSetLength(5);
CString str("Hello World"); LPTSTR lpBuffer = str.GetBuffer(0); //do something with lpBuffer str.ReleaseBufferSetLength(-1);In this example, the same as above, a pointer to the internal buffer of the CString object is obtained. After manipulation, ReleaseBufferSetLength(-1) is called to release the buffer and reset the length of the CString to the actual length of the manipulated string. Overall, CString ReleaseBufferSetLength is part of the MFC library in C++ and is used to release the internal buffer of a CString object and set the length to a new value.
