显示实时实时变化的数

fj1303020304 · 发表于 2017-6-12 10:15:10

请教一下，我现在用EMWIN能显示出时间，但是不能够实现实时刷新，请问是哪儿的问题？
还有一个问题就是怎么将函数的返回值显示出来？以下是我的程序，请问是什么地方不对啊？非常感谢！

static void _cbDialog(WM_MESSAGE * pMsg) {
  WM_HWIN hItem;
int    NCode;
  int    Id;

  switch (pMsg->MsgId) {

      case WM_PAINT:

         GUI_SetFont(&GUI_FontHZ16);
         GUI_SetColor(GUI_BLACK);
         GUI_GetTime();
         sprintf((char*)ttbuf1,"%02d-%02d-%02d",calendar.w_year,calendar.w_month,calendar.w_date);
         GUI_DispStringAt((const char*)ttbuf1,65,13);
         sprintf((char *)ttbuf1,"%02d:%02d:%02d",calendar.hour,calendar.min,calendar.sec);
         GUI_DispStringAt((const char*)ttbuf1,155,13);


         WM_CreateTimer(TextDialoghWin,0,100,0);
      break;

break;

NCode = pMsg->Data.v;
//    switch(Id)
