虽然研究的URLConnection类我偶然在一个参考系统默认包中的API文档URL类在这里.

谁知道那是什么？
谢谢.

我想弄清楚一些java代码.我在方法标题中遇到了一些我以前没见过的东西

private static object [] methodName(NodeList nodes, String... Names)

什么是运营商...？

谢谢,抱歉,有些搜索在其他地方找不到

我在"wave"中返回控制台输出时遇到问题.例如,控制台每秒输出一些东西,例如事件每分钟触发60次(同时所有事件).

我的代码:

Process Proc = new Process();
Proc.StartInfo.FileName = SSMS.BinaryDir + "HldsUpdateTool.exe";
Proc.StartInfo.Arguments = "-command update -game tf -dir " + SSMS.RootDir + Key;
Proc.StartInfo.UseShellExecute = false;
Proc.StartInfo.RedirectStandardOutput = true;
Proc.StartInfo.RedirectStandardError = true;

Proc.EnableRaisingEvents = true;
Proc.StartInfo.CreateNoWindow = false;

Proc.ErrorDataReceived += new DataReceivedEventHandler(Proc_ErrorDataReceived);
Proc.OutputDataReceived += new DataReceivedEventHandler(Proc_OutputDataReceived);
Proc.Exited += new EventHandler(Proc_Exited);

Proc.Start();
Proc.BeginErrorReadLine();
Proc.BeginOutputReadLine();

我可能怀疑更新工具有问题.其他带控制台输出的程序运行正常.

触发事件时的时间线:( =什么都没发生; |事件被触发)

如何捕获WinForm主窗体的键盘事件,其他控件是.所以我想抓住一个事件Ctrl+ S并且无关紧要.但是没有Pinvoke(钩子等......)只有.NET管理内部电源.

我有一个Silverlight 4应用程序,在表单底部附近有一个ComboBox.Dropdown中可以有大约30到100个项目.

当我第一次打开ComboBox时,没有SelectedItem,Dropdown向上打开,它可以看到大约23个条目; 只要我没有选择项目,每次重新打开Dropdown时它都会继续这种行为.一旦我选择了一个项目,每次我打开ComboBox后,它总是向下打开Dropdown,并且只显示3个条目.

我猜Dropdown仅限于3项,因为这是我在屏幕上最大化时窗口的下限.

即使先前已选择某个项目,如何让它显示更多项目？

下面是一个示例Silverlight应用程序,它演示了浏览器内外的行为.

我正在尝试使用NUnit对自定义WPF控件进行单元测试.该控件是按钮的ListView,绑定到列表(DataContext在控件的构造函数中设置).

我想编写测试(例如)将项目添加到列表中并检查是否有新按钮添加到视图中等等.但是,当我在NUnit测试中将项目添加到列表时,它仍会报告ListView为空.但是,当我运行我的应用程序时,一切正常.

我在下面列出了相关代码.我需要做些什么来测试这个？

XAML:

<ListView x:Class="SoundBlock"
          xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
          xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
          xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
          xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
          ItemsSource="{Binding Path=Sounds}">
    <ListView.ItemTemplate>
        <DataTemplate>
            <Button Content="{Binding Title}" />
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

类定义

public partial class SoundBlock : ListView
{
    public SoundBlock(Board xiBoard)
    {
        // Initialize.
        InitializeComponent();

        // Set the data context for this block.
        DataContext = xiBoard; // Board has an ObservableCollection<Sound> 
                               // property called Sounds.
    }
}

测试用例

[Test]
public void TestAddSound()
{
    board = new Board();
    block = new SoundBlock(board);
    Assert.AreEqual(0, block.Items.Count);

    sound = new Sound("sound.mp3");
    board.Sounds.Add(sound);
    Assert.AreEqual(1, …

如何在运行时更改WPF静态资源的值？

我有以下资源

<UserControl.Resources>
    <sys:String x:Key="LengthFormat">#.# mm</sys:String>
    <sys:String x:Key="AreaFormat">#.# mm²</sys:String>
    <sys:String x:Key="InertiaFormat">#.# mm?</sys:String>
</UserControl.Resources>

一些文字块参考

<TextBlock Grid.Row="2" Grid.Column="1" 
 Text="{Binding Path=Breadth, StringFormat={StaticResource ResourceKey=LengthFormat}}" />

然后根据要绑定到控件的对象,我想改变格式.我在控件中设置了如下属性:

public string LengthFormat
{
    set
    {
        this.Resources["LengthFormat"] = value;
    }
}
public string AreaFormat
{
    set
    {
        this.Resources["AreaFormat"] = value;
    }
}
public string InertiaFormat
{
    set
    {
        this.Resources["InertiaFormat"] = value;
    }
}

然后在绑定之前我设置每个字符串.

但它不起作用,有人建议whynot？

干杯

包含Javascript <head>与OPENING <body>标签之后的相反有什么区别？

Facebook Like小部件就是一个例子,他们建议在开始<body>标记之后立即放置代码.SiteCatalyst还建议使用它们的分析代码.

虽然在<head>元素中包含代码而不是在结束</body>标记之前存在明显的区别,但我不确定<head>开始<body>标记之后和之后的区别.
