CEdit实现文本换行

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

DWORD dwStyle = WS_VISIBLE | ES_MULTILINE | ES_WANTRETURN;
CEdit *pEdit = new CEdit;
RECT rect = {0, 0, 80, 80};
pEdit->Create(m_hWnd, rect, NULL, dwStyle);
HFONT hfont = (HFONT)GetStockObject(SYSTEM_FONT);

pEdit->SetFont(hfont);
pEdit->SetWindowText("
Hello,World.");
