Writing values of a file to a text box in MFC

Hi,
Im trying to write to an edit control window in and MFC project. Im reading values from a file into a string, and im using IDC_OUT.SetWindowText(stringtoprint). This gives me an error"CWnd::SetWindowTextA' : cannot convert parameter 1 from 'std::string' to 'LPCTSTR'".

How else can I write to the text box?Thanks!

Use explicit std::string method:
IDC_OUT.SetWindowText(stringtoprint.c_str()).

THanks!

      fstream foutput;

      foutput.open("resultsfile.txt");
        if (foutput.is_open())
        {
            while (! foutput.eof() )
            {
                  getline (foutput,output);
                  IDC_OUT.SetWindowText(output.c_str());

Hello
Use ReplaceSel CEdit method
example
{
    fstream foutput;

      foutput.open("resultsfile.txt");
        if (foutput.is_open())
        {
            while (! foutput.eof() )
            {
                  int len = IDC_OUT.GetWindowTextLength();
                  IDC_OUT.SetSel(len, len);
                  getline (foutput,output);
                  IDC_OUT.ReplaceSel(output.c_str());
            }
            foutput.close();
      }}
