MFC question...

I have a problem to write an MFC application that will display whatever the user types in the client area. Also I need to restore (repaint) everything when user minimize the window.

Right now I am using the code from the book that allows user to enter one char and to restore the same one but I dont know how to that for more lines. New line should start when user press enter.

Code:

---


// Process a WM_CHAR message.
afx_msg void CMainWin::OnChar(UINT ch,
                              UINT count, UINT flags)
{
  CClientDC dc(this);

  dc.TextOut(1, 1, "  ", 3); // erase previous char

  wsprintf(str, "%c", ch);
  dc.TextOut(1, 1, str, strlen(str));


}

// Process a WM_PAINT message.
afx_msg void CMainWin::OnPaint()
{
  // If we use CClientDC instead we will have a LOT of paint messages.
  CPaintDC dc(this);

  // this line redisplays the last character
  dc.TextOut(1, 1, str, strlen(str));
}

---

this is what i'm using so far (copy/paste from the book)

everything will help
Thanks

Instead of using a char* you should change it to using CString (MFC) or string (STL) that way in the OnChar() function you could do variable += ch to add the char on the end of the string.
