    problem outputing data from internetreadfile()

    this is the code I'm having problems with(internetopen/connect and httpopenrequest all work):

    Code:
    DWORD bytesRead;
    wchar_t temp[1025] = L"";
    if (InternetReadFile(irequest, (LPVOID)temp, 1024, &bytesRead) == TRUE && bytesRead > 0)
    {
    	TextOut(hdc,700,100, (LPCWSTR)temp, sizeof(temp)); 
    }
    there is no error-code, but as output I get chinese sings, does anyone know what goes wrong?

    InternetReadFile reads bytes and then you are trying to output them as wide chars in TextOut. If you are using Unicode, then you need to convert the bytes read by InternetReadFile into wide chars before passing to TextOut.

All my code is tested (unless stated explicitly otherwise) with the latest version of Microsoft Visual Studio (using the supported features of the latest standard) and is offered as examples only - not as production quality. I cannot offer advice regarding any other c/c++ compiler/IDE or incompatibilities with VS.
