我有程序MSMQ使用GetAllMessages 读取,但它不会从队列中删除消息,所以我有以下代码; 不断获得相同的消息.我不想一次又一次地处理同样的消息.如何确保MSMQ删除已收到的消息或至少我没有收到消息？

while()
{
    Messages[] receivedMessage = queue.GetAllMessages()

    foreach(Message msg in receivedMessage)
    {
        ... Processing
    }
}

我一直很难找到一个易于学习的教程或使用Ninject使用拦截扩展的例子,或者理想情况下是一个工作示例.

我已经尝试了下面的教程,但是立即遇到了让命名空间用于the Intercept()调用的问题:

我有2组数据:

现在我想找到一个使用StableDistribution []的估计分布

对于第一个数据集,我执行以下操作:

dist1 = EstimatedDistribution[d1, StableDistribution[alpha, beta, mu, sigma]]

我得到一条消息和输出

FindMaximum::sdprec: Line search unable to find a sufficient increase in the function value with MachinePrecision digit precision. >>

StableDistribution[1,0.863446,1.,-0.0781627,0.0345779]

输出看起来不错(不太适合数据,但也不是太糟糕)但是消息对输出意味着什么？

对于第二个数据集,d2

 dist2 = EstimatedDistribution[d2, StableDistribution[alpha, beta, mu, sigma]]

我收到了不同的消息.

Optimization`ModifiedCholeskyDecomposition::herm: The matrix {{2.76856*10^157,-1.75574*10^159,-1.84519*10^157,-2.26892*10^157},{7.88598*10^159,0.,6.41507*10^159,7.88598*10^159},{1.82386*10^157,6.41507*10^159,1.13495*10^157,1.82386*10^157},{-2.26892*10^157,-1.75574*10^159,-1.84519*10^157,1.68961*10^157}} is not Hermitian or real and symmetric.

并输出:

StableDistribution[1,0.834688,1.,-0.0101189,0.0181306]

所以,我有几个问题.谁能解释这些消息及其相关性？在我看来,Mathematica尝试了许多不同的方法来估计分布,有些方法不能很好地工作.

谢谢.

单元是一个类还是一个组件(多个类)？

什么应该是单元测试？一个单位的粒度应该多少？

我注意到Silverlight for Windows Phone 7中缺少Effect Property,所​​以我做了一些谷歌搜索,并且由于性能原因,它显然被删除了.我基本上想做这样的事情

<TextBlock ...>
    <TextBlock.Effect>
        <DropShadowEffect/>
    </TextBlock.Effect>
</TextBlock>

和

<Image ...>
    <Image.Effect>
        <DropShadowEffect/>
    </Image.Effect>
</Image>

那么有没有其他方法来获得DropShadowEffectSilverlight for Windows Phone 7？有没有新闻,如果它将在下一个版本中？

谢谢

我有一个python类"foo",其中包含:

• 数据(整数,浮点数)
• 列表(整数,浮点数和其他对象)
• 字典(整数,浮点数,其他对象)

假设没有反向引用(循环),是否有一种简单的方法来衡量"foo"对象的总内存使用量？

基本上,我正在寻找"sys.getsizeof" 的递归版本

少数的,我碰到的工具包括:heapy,objgraph和GC,但我不认为任何人都能够胜任工作(我可以在此进行校正)

建议赞赏!

我试图实现一个专门的集合,其工作就像ObservableCollection封装了一些更多的机制,为此我也让我的集合继承Collection而且我也实现了相同的接口.

我只是不知道如何实际实现整个集合 - 更改 - 逻辑,例如Collection<T>.Add没有被覆盖(它甚至没有标记为虚拟),那么如果使用该方法添加项目,如何ObservableCollection触发CollectionChanged事件？

它似乎只是在开发服务器端代码时非常有用的东西.如果您知道浏览器不会在服务器端使用javascript,则可以轻松容纳用户.或者,如果你只是觉得它,将它们重定向到一个页面,上面写着'嘿......我们需要你为我们的应用程序使用javascript'等.

有人知道为什么吗？

我正在研究缓冲区溢出(在IA32架构上),我想用这个示例程序澄清一个特殊的事情:

int main(int argc, char **argv) {
  char array[512];
  if(argc > 1)
    strcpy(array, argv[1]);
}

我在执行汇编代码时跟踪了ebp,esp寄存器更改:函数main的汇编代码转储:

   0x080483c4 <+0>:     push   ebp
   0x080483c5 <+1>:     mov    ebp,esp
   0x080483c7 <+3>:     sub    esp,0x208
   0x080483cd <+9>:     cmp    DWORD PTR [ebp+0x8],0x1

是否可以使用COM将自定义对象(如MyClass [])从C#传递给VBA？

如果没有,哪个是最好的解决方案让这个工作？
