怎么成功在UCGUI中改变EDIT的值？

我想按键一按下去就改变EDIT中的值，但我像下面这样写，按键一暗下去就会死机，不知道问什么，有没有人能说一下？
sta tic void _cbDialog(WM_MESSAGE * pMsg) {
WM_HWIN hItem;
int NCode;
int Id;
// USER START (Optionally insert additional variables)
// USER END
switch (pMsg->MsgId) {
case WM_INIT_DIALOG:
//
// Initialization of 'Edit'
//
hItem = WM_GetDialogItem(pMsg->hWin, ID_EDIT_0);
// EDIT_SetText(hItem, "123");
EDIT_SetDecMode(hItem,0,0,1000,0,0);
EDIT_SetValue(hItem, 23);
// USER START (Optionally insert additional code for further widget initialization)
// USER END
break;
case WM_NOTIFY_PARENT:
Id = WM_GetId(pMsg->hWinSrc);
NCode = pMsg->Data.v;
switch(Id) {
case ID_BUTTON_0: // Notifications sent by 'Button'
switch(NCode) {
case WM_NOTIFICATION_CLICKED:
// EDIT_SetDecMode(hItem,0,0,1000,0,0);
EDIT_SetValue(hItem, 800);
//GUI_Exec1();
//GUI_CreateDialogBox(_aDialogCreate, GUI_COUNTOF(_aDialogCreate), _cbDialog, WM_HBKWIN, 0, 0);
//EDIT_SetValue(hItem, 23);
//EDIT_SetText(hItem, "ad");
// USER START (Optionally insert code for reacting on notification message)
// USER END
break;
case WM_NOTIFICATION_RELEASED:
// USER START (Optionally insert code for reacting on notification message)
// USER END
break;
// USER START (Optionally insert additional code for further notification handling)
// USER END
}
break;
case ID_EDIT_0: // Notifications sent by 'Edit'
switch(NCode) {
case WM_NOTIFICATION_CLICKED:
// USER START (Optionally insert code for reacting on notification message)
// USER END
break;
case WM_NOTIFICATION_RELEASED:
// USER START (Optionally insert code for reacting on notification message)
// USER END
break;
case WM_NOTIFICATION_VALUE_CHANGED:
// USER START (Optionally insert code for reacting on notification message)
// USER END
break;
// USER START (Optionally insert additional code for further notification handling)
// USER END
}
break;
// USER START (Optionally insert additional code for further Ids)
// USER END
}
break;
// USER START (Optionally insert additional message handling)
// USER END
default:
WM_DefaultProc(pMsg);
break;
}
