Don’t use Marshal::StringToHGlobalUni<\/code> in C++\/CLI.<\/p>\n

Use either<\/p>\n

    \n
  1. PtrToStringChars<\/code> (accesses Unicode characters in-place, no allocation) or<\/li>\n
  2. marshal_as<std::wstring><\/code> (manages the allocation with a smart pointer class that will free it correctly and automatically)<\/li>\n<\/ol>\n

    Apart from the fact that StringToHGlobalUni<\/code> requires you to free the memory manually, the name of that function is completely misleading. It has absolutely no connection to HGLOBAL<\/code> whatsoever.<\/p>\n<\/p><\/div>\n
