Win32 SDK创建RichEdit Control控件

HMODULE hRichEditDll = NULL;

WM_CREATE:
{
 hRichEditDll = LoadLibrary(_T("RICHED20.dll"));
 HWND hRichEdit = CreateWindowEx(WS_EX_CLIENTEDGE,
  _T("RichEdit20W"), 
  NULL,
  WS_CHILD | WS_VISIBLE | WS_VSCROLL | WS_HSCROLL | ES_MULTILINE | ES_NOHIDESEL,
  0, 0, 100, 100, hWnd, 0, hInstance, 0);
}
break;

// 最后释放DLL
FreeLibrary(hRichEditDll);hRichEditDll = NULL;

利用CreateWindowEx创建RichEdit Control之前，需先加载RICHED20.dll这个库，然后才可以CreateWindowEx(..,_T("RichEdit20W"),...);否则的话,CreateWindowEx会失败，GetLastError()返回值为1407: 找不到窗口类名.
