title: Richedit control display the content of a string in winAPI c++ app
body: <p>I have a richedit control on a dialog. I want to populate the richedit control with a string. The richedit control itself displays properly. But I don't know how to populate the richedit control with a string. I took a guess at it below, in the resource.rc code.</p>
  
  <p>In main.cpp, I have:</p>
  
  <pre><code>case IDC_BUT_ABOUT:
              {
                  HINSTANCE   hRichEdit;  
                  hRichEdit = LoadLibrary("RICHED32.DLL"); 
                  DialogBox( hInst, MAKEINTRESOURCE(IDD_ABOUT), hDlgWnd,(DLGPROC)InitAbout );
                  //ShowWindow(hDlgWnd, SW_SHOWNORMAL); 
                  return TRUE;
              }
              break;
  </code></pre>
  
  <p>In resource.rc, I have:</p>
  
  <pre><code>IDD_ABOUT DIALOGEX 0, 0, 206, 136
  STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | DS_CENTER | WS_POPUP | WS_CAPTION | WS_SYSMENU
  CAPTION "About"
  FONT 8, "MS Shell Dlg", 400, 0, 0x1
  BEGIN
      PUSHBUTTON      "Close",IDCANCEL,77,115,50,14
      CONTROL         "",IDC_RICHEDIT21,"RichEdit20W",ES_AUTOHSCROLL | ES_READONLY | WS_BORDER | WS_TABSTOP,36,53,130,46
  END
  
  string rt  = "{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0     Arial;}{\f1\fnil\fprq2\fcharset0 Biondi;}}{\colortbl ;\red255\green0\blue0;}\viewkind4\uc1\pard\f0\fs20\par\cf1\f1 hello\cf0\f0  \ul some text here\par}";
  
  this.IDC_RICHEDIT21.Rtf = rt;
  </code></pre>
  
  <p>But this apparently isn't even close to how I should put text from a string into a rich edit control?</p>
