    Resolved [RESOLVED] SysAllocString

    Hi all,

    Code:
    BSTR tmp = SysAllocString(L"Hello world");
    It works! But

    Code:
    char mystr[] = "Hello world";
    BSTR tmp = SysAllocString(mystr);
    Does not compile. Any hint?

    Thanks,

    Cristina

    [SOLVED] Re: SysAllocString

    Finally, I solved as follows:

    Code:
    string str="Hello World";
    int wslen = ::MultiByteToWideChar(CP_ACP, 0 /* no flags */,
                                          str.data(), str.length(),
                                          NULL, 0);
    BSTR wsdata = ::SysAllocStringLen(NULL, wslen);
    ::MultiByteToWideChar(CP_ACP, 0 /* no flags */,
                              str.data(), str.length(),
                              wsdata, wslen);
    
    BSTR tmp = SysAllocString(wsdata);

    You can do it by clicking on "Thread tools" just above the first post in this thread, then "Mark thread resolved". (like various other features of this site, you need JavaScript enabled in your browser for this to work).
