c++ - Error 12006 in WinHttpCrackUrl -


i'm trying build address variable. can pass winhttpopenrequest.

    char *unameaddr = (char*) exebaseaddress + 0x34f01c;     printf("%s \n", unameaddr);      string url = "http://xxxx.xxxx.com/xxxx/?u=";     string username = unameaddr;       string combine = url + username;      cout << combine << endl;     //http://xxxx.xxxx.com/xxxx/?u=myusername <--      url_components urlcomp;     lpcwstr pwszurl1 = (lpcwstr)combine.c_str();     dword dwurllen = 0;

then have pass here:

hrequest = winhttpopenrequest( hconnect, l"get", urlcomp.lpszurlpath,                                null, winhttp_no_referer,                                winhttp_default_accept_types,                                0);

urlcomp.lpszurlpath should http://xxxx.xxxx.com/xxxx/?u=myusername

any advice? application crashes when gets process part.

error

 12006       error_internet_unrecognized_scheme              url scheme not recognized or not supported. 

lpcwstr pwszurl1 = (lpcwstr)combine.c_str();

std::string::c_str returns const char *. lpcwstr const wchar_t *.

casting lpcwstr lying compiler , yourself, combine.c_str() returns not pointer wide-character string.

you'll have better success std::wstring, represents wide-character strings.

consider reading unicode in windows api more information.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
