用C语言编写的替代Boost.Program_options的任何好的替代方案？鉴于它能够解析:

1. 短期选项如-h
2. 像--help --input-file这样的长选项
3. 解析重复的键/选项
4. 接受键值对: - mysql =/usr/lib
5. 解析环境变量和XML/INI文件是可选的.

我总是想知道这一点,但为什么运算符重载不适用于Delphi中的类？

我记得在跑步时读了一次答案,它说它会与某些东西发生冲突,但我记不起来了.据我所知,只有隐式运算符可能会导致一些问题,因为类存储在堆上并且赋值实际上是堆地址的副本(基本上是复制指针).

我想检查一个数字是否可被6整除,如果不是,我需要增加它直到它可以被整除.

我怎样才能做到这一点 ？

我有一个测试用例:

class LoginTestCase(unittest.TestCase):
    ...

我想在不同的测试用例中使用它:

class EditProfileTestCase(unittest.TestCase):
  def __init__(self):
    self.t = LoginTestCase()
    self.t.login()

这引起了:

ValueError: no such test method in <class 'LoginTest: runTest`

我查看了调用异常的unittest代码,看起来测试不应该以这种方式编写.是否有标准的方法来编写您要测试的内容,以便以后的测试可以重用它？或者有解决方法吗？

我现在添加了一个空runTest方法LoginTest作为一个可疑的解决方法.

我现在正在研究其他用户的PHP代码,以便更好地理解和学习.在下面的代码中,它是用户类的一部分.当我使用if/else块进行编码时,我将它们格式化为...

if(!$this->isLoggedIn()){
    //do stuff
}

但是在下面的代码中它更像是这样

if (! $this->isLoggedIn())
    return false;

同样在下面的函数中,您可以看到有几次可以有RETURN值.所以我的问题在于,当调用RETURN时,它之后是否运行任何代码？就像它结束那个功能的脚本那样？

在这种情况下,如果这是...

if (! $this->isLoggedIn())
        return false;

Does it continue to run the code below that?

Here is the function

<?PHP
private function logout($redir=true)
{
    if (! $this->isLoggedIn())
        return false;

    $this->obj->session->sess_destroy();

    if ($this->isCookieLoggedIn())
    {
        setcookie('user','', time()-36000, '/');
        setcookie('pass','', time()-36000, '/');
    }
    if (! $redir)
        return;

    header('location: '.$this->homePageUrl);
    die;
}
?>

It makes me confused when I read the article by Zarko Gajic today:

"Multithreaded Delphi Database Queries"

Article URL: http://delphi.about.com/od/kbthread/a/query_threading.htm

With the code of "TCalcThread.Execute" procedure, Why the following code do not need to be placed in the Synchronize() method to run?

Line 188:    ListBox.Items.Add('*---------*');

These codes are operating the VCL components, and are related to the UI updates. In my knowledge, …

I'm trying to display a Wpf Treeview with items sorted by a CollectionViewSource.

Currently, everything is working except sorting using this code in my resource dictionary:

<HierarchicalDataTemplate DataType="{x:Type books:Container}" ItemsSource="{Binding Path=Items}">
    <nav:ContainerControl />
</HierarchicalDataTemplate>

What would be the syntax for changing the HierarchicalDataTemplate to bind to a CollectionViewSource that in turn pulls from the Items property?

I've tried variations of the code posted on Bea Stollnitz's blog with no success. I can't figure out how to set the source of …

Is there a way to determine the Object type, when passing a reference to a function?

I'm using a security permissions function, which determines if the user has permission to view/edit the Form passed to it by reference. I'd like to expand this to include reports as well.

To keep the function generic, I'd like to pass a ref for either a Form or a Report as an Object, eg: function gfSecurity_Permission(obj as Object)

但是,我需要确定type函数中的对象.

有谁知道这样做的方法？
