Using console in VCL applications

Is there a way for using the console for output in VCL applications? Where does cout actually direct the stream in VCL applications?

Solution

  • I did it as follows:

    void TForm1::Button1Click(TObject *Sender)
{
    out_to_console("Some text\n");
}
void out_to_console(std::string str)
{
    AllocConsole() ;
    AttachConsole(GetCurrentProcessId()) ;
    std::freopen("CON", "w", stdout) ;
    std::cout<<str;
}

    Two questions still remain for me open:

    1. Why I need the escape sequence \n to see the text Some text on the console?
    2. Where does stdoutpoint to in VCL applications?
