c++ - 如何接收来自 Windows MessageBox 的反馈？

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使用react(比如如果他们单击"is"则关闭窗口)？

Answer 1

MessageBox将返回一个整数，指的是按下的按钮。来自上一个链接:

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.

所以像这样:

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