我用MFC控件做的小程序，但编译不通过，大家帮我看看
#include "stdafx.h"
#include "TEST.h"
#include "TESTDlg.h"
#ifdef _DEBUG
#define new DEBUG_NEW
#undef THIS_FILE
static char THIS_FILE[] = __FILE__;
。。。。。。。。。。。。
void CTESTDlg::OnOk6()
{
cstatic* static1=(cstatic*)getdlgltem(idc_static1);
static1->setwindowtext("明日科技")；
    
}

void CTESTDlg::OnOk7()
{
   if(!iswindow(m_dynamic.m_hwnd))
       m_dynamic.create("欢迎你！",ws_child,crect(110,50,180,100),this,1525);
   m_dynamic.showwindow(sh_show);

}
