Dynamic Memory Deletion in vc++

enter image description hereI am using _aligned_malloc in my code. But it is throwing error error as shown in image.

CString sBuffer = _T("Hello");
TCHAR*   pBuffer; 

pBuffer = (TCHAR *)_aligned_malloc(1024, 16);

if (pBuffer == NULL) {
    ...............Error .. msg 
}

pBuffer =  sBuffer.GetBuffer(sBuffer.GetLength());

..................................................
.........................................................

sBuffer.ReleaseBuffer(sBuffer.GetLength());

if (pBuffer != NULL) {
    _aligned_free(pBuffer);
}

The CString class implements (LPCTSTR) cast operator that you can use to get const TCHAR*. Please note that TCHAR is defined as char in MBCS mode, and as wchar in UNICODE mode. For more details please refer to tchar.h where its defined.

If you'd like to modify the content of the buffer you'll need to use GetBuffer() method. Don't forget to call ReleaseBuffer() when you done. So, there is no need to allocate memory manually.

You can also easily construct CString from TCHAR*. There is a constructor to do that.
