CEdit实现文本换行

CEdit控件若要在字符串中插入换行字符("\r\n")实现换行效果，必须指定两个风格 ES_MULTILINE和ES_WANTRETURN。

   1: DWORD dwStyle = WS_VISIBLE | ES_MULTILINE | ES_WANTRETURN;

   2: CEdit *pEdit = new CEdit;

   3: RECT rect = {0, 0, 80, 80};

   4: pEdit->Create(m_hWnd, rect, NULL, dwStyle); 

   5: HFONT hfont = (HFONT)GetStockObject(SYSTEM_FONT);

   6:  

   7: pEdit->SetFont(hfont);

   8: pEdit->SetWindowText("\r\nHello,World.");
