我的窗体是主窗体，试了下你们的方法，直接关闭了
而 FormCloseQuery 方法的能隐藏第一次，第二次再让他隐藏它就不甩我了

在窗体的OnCloseQuery事件里，
void __fastcall TForm1::FormCloseQuery(TObject *Sender, bool &CanClose)
{
CanClose=false; //不退出
this->Visible =false; //隐藏窗体。
}
但是要再让它显示出来，得有个地方将该窗体Visible=true;
void __fastcall TForm1::FormCloseQuery(TObject *Sender, bool &CanClose)
{
CanClose=false; //不退出
this->Visible =false; //隐藏窗体。
}

Action: 的取值有
Value Meaning
caNone
The form is not allowed to close, so nothing happens.
caHide
The form is not closed, but just hidden. Your application can still access a hidden form.
caFree
The form is closed and all allocated memory for the form is freed.
caMinimize
The form is minimized, rather than closed. This is the default action for MDI child forms.
