如何从Windows MessageBox接收反馈？

Question

我知道可以用Windows做这样的事情：

MessageBox(hWnd, "Yes, No, or Cancel?", "YNCB_YESNOCANCEL);

但是我如何对用户按下的内容作出反应（如果点击“是”时关闭窗口）？

Answer 1

MessageBox将返回一个指向按下按钮的整数。从上一个链接：

Return Value
    IDABORT      Abort button was selected.
    IDCANCEL     Cancel button was selected.
    IDCONTINUE   Continue button was selected.
    IDIGNORE     Ignore button was selected.
    IDNO         No button was selected.
    IDOK         OK button was selected.
    IDRETRY      Retry button was selected.
    IDTRYAGAIN   Try Again button was selected.
    IDYES        Yes button was selected.

类似于：

int result = MessageBox(hWnd, "Save work?", MB_YESNOCANCEL);
if (result == IDOK)
{
    // ...
}
else if (result == IDNO)
{
    // ...
}
else // cancel
{
    // ...
}

Answer 2

int result = MessageBox(hWnd,_T(""),_T("Save work?"), MB_YESNOCANCEL);
if (result == 6){
    MessageBox(NULL, _T("YES"),_T("Press"),MB_OK);
}
else if (result == 7){
    MessageBox(NULL, _T("NO"),_T("Press"),MB_OK);
}
else{
    MessageBox(NULL, _T("CANCEL"),_T("Press"),MB_OK);
}
