Question

用什么类型变量保存Dlg.Domodal按钮返回值？

弹出对话框有三个按钮，请问用什么变量来保存返回值？方便做多次判断.
如：CDlgOver dlg;
if(dlg.Domodal()==ID_REPLAY)
{Replay();}
这样可以判断“重玩”,但是怎么判断ID_QUIT呢？
而：if(dlg.Domodal()==ID_REPLAY)
{Replay();}
if(dlg.Domodal()==ID_QUIT)
{Quit();}
这样，又会弹出两个对话框

Answer 1

int iDlgRet = dlg.DoModal();
if( iDlgRet == ID_REPLAY )
{
}
else if( iDlgRet == ID_QUIT )
{
}
