How using code from MSVC C++

[Mikeeeeee]

Hi!
I have this code [this code(https://www.experts-exchange.com/articles/3096/Convert-RTF-to-HTML-and-HTML-to-RTF.html).
How I con using this code in QT?

// Rtf2Html.cpp : Defines the entry point for the console application. 
// 
#include "stdafx.h" 
#include "Rtf2Html2.h" 
#include "afxhtml.h" 
 
CWinApp theApp;  // Win32 App with MFC support 
 
CRichEditCtrl g_ctlRichEdit;  // the two controls 
CHtmlEditCtrl g_ctlEditHtml; 
 
// This is needed to load the RichEdit control from a file 
static DWORD CALLBACK  
MyStreamInCallback(DWORD dwCookie, LPBYTE pbBuff, LONG cb, LONG *pcb) 
{ 
   CFile* pFile = (CFile*) dwCookie; 
   *pcb = pFile->Read(pbBuff, cb); 
   return 0; 
} 
 
void LoadRtfFile( LPCTSTR pszFilename ) 
{ 
    wchar_t szFilter[] = L"RTF files (*.rtf)|*.rtf;|" 
                         L"All Files (*.*)|*.*||"; 
    CFileDialog dlg(TRUE,0,pszFilename,6,szFilter ); 
    if ( dlg.DoModal()!=IDOK ) { 
        return; 
    } 
    CFile cf( dlg.GetPathName(),CFile::modeRead ); 
 
    // CFile cf( pszFilename,CFile::modeRead ); 
    EDITSTREAM es; 
    es.dwCookie = (DWORD)&cf; 
    es.pfnCallback = MyStreamInCallback;  
    g_ctlRichEdit.StreamIn( SF_RTF, es ); // load from the file 
} 
 
int _tmain(int argc, TCHAR* argv[], TCHAR* envp[]) 
{ 
    AfxWinInit(::GetModuleHandle(NULL), NULL, ::GetCommandLine(), 0); 
    AfxInitRichEdit2(); // needed for using CRichEditCtrl 
 
    CWnd* pWnd = CWnd::GetDesktopWindow(); 
    CRect r(0,0,200,200); 
 
    g_ctlRichEdit.Create( ES_MULTILINE, r, pWnd, 1111); 
    g_ctlEditHtml.Create( 0,0, r, pWnd, 2222 ); 
 
    LoadRtfFile( argv[1] );     // read the RTF file into the ctrl  
    g_ctlRichEdit.SetSel(0,-1); // select all in the RTF ctrl 
    g_ctlRichEdit.Copy();       // copy to clipboard 
    g_ctlEditHtml.Paste();      // paste into the Html Edit ctrl 
    g_ctlEditHtml.SaveAs( L"C:\\temp\\test.html");  // save HTML 
 
    return 0; 
}

Well, copy paste and change what needs to be changed.
Your question is too generic.
For example remove this CWinApp thing and use QApplication instead.
This code uses some libraries (Rtf2Html2, afxhtml) you will need to add them to your project if there is no replacement in Qt.
