I have the following style applied to treeviewitem container. Basically, used to override selection color: <Style x:Key="element-designer-node-host" TargetType="{x:Type TreeViewItem}"> <Style.Resources> <SolidColorBrush x:Key="{x:Static SystemColors.ControlBrushKey}" Color="{DynamicResource nav-tvi-sel-bg1}" /> <SolidColorBrush

I'm now looking for quite some time for a solution to this, and nothing worked for me until now: I have a C# console application from which i open an Application in a new Window that i designed using the designer. I made a new solution and copied the window in the new solution and now the designer throws the upper exception. The program itself runs well but the designer simply denies to w
我现在正在寻找相当长的一段时间来解决这个问题，到现在为止我还没有为我工作： 我有一个C＃控制台应用程序，我使用设计器在一个新窗口中打开应用程序。 我提出了一个新的解决方案，并在新的解决方案中复制了窗口，现在设计者抛出了上面的异常。 程序本身运行良好，但设计者拒绝工作。 使用的代码是： <Window ...Some Description...> <DockPanel>...Content...>/DockPanel> </Window> 在
I'm writing a WPF 4 app (with VS2010 RC) using MVVM Light V3 alpha 3 and am running into some weird behaviour here... I have a command that opens a Window , and that Window creates the ViewModel and so on - nothing weird there. In that Window I have some RelayCommand s, for example: CategoryBeenSelected = new RelayCommand(() => OnCategoryUpdate = true); Nothing weird again - it works
我正在使用MVVM Light V3 alpha 3编写WPF 4应用程序（使用VS2010 RC），并在这里遇到一些奇怪的行为... 我有一个打开Window的命令，并且该窗口创建ViewModel等等 - 在那里没什么奇怪的。 在那个Window我有一些RelayCommand ，例如： CategoryBeenSelected = new RelayCommand(() => OnCategoryUpdate = true); 没有什么奇怪的 - 它按我的预期工作。 问题是我不能有一个通用的RelayCommand的CanExecute方法/ lambda表
I would like to understand how this particular case works. Here is the shot from msdn article where INotifyPropertyChanged interface is explained (https://msdn.microsoft.com/query/dev12.query?appId=Dev12IDEF1&l=EN-US&k=k%28System.ComponentModel.INotifyPropertyChanged%29;k%28TargetFrameworkMoniker-.NETFramework,Version%3Dv4.5%29;k%28DevLang-csharp%29&rd=true) As it's said in mar

I can no longer create log files with ASP.NET RC1 and the HttpPlatformHandler. This is the warning in the event log: The description for Event ID 1004 from source HttpPlatformHandler cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event o
我不能再使用ASP.NET RC1和HttpPlatformHandler创建日志文件。 这是事件日志中的警告： The description for Event ID 1004 from source HttpPlatformHandler cannot be found.

If the event originated on another computer, the
I'm using a diagram control which contains a Node with links to its parents as well as its children. I want to flatten the tree but in order. What's the fastest and most efficient way to do this; preferably in C#. Here's an example of a tree. I'm having difficulties coming up with a good description of the order so I apologize. The order should list all nodes in order of th
我正在使用一个图表控件，其中包含一个带有指向其父母及其子女的链接的节点。 我想扁平化树，但要按顺序。 什么是最快和最有效的方式来做到这一点; 最好用C＃。 这是一个树的例子。 我很难提出对订单的很好的描述，所以我很抱歉。 订单应按照其创建顺序列出所有节点。 例如，在树木击打中，有效顺序是（Root，A，B，C，G，D，H，E，F）。 这个命令保证没有节点被添加到它的父节点之前的列表中。 你的图不是树，因为一
I tend to use either getopt() or getopt_long to parse command-line arguments when working with console-based programs. However, most of the time I end up using global variables to store configuration parameters that I can use across all *.c files. So I'm interested to know what patterns do you use, and what would be a better alternative to global variables. I generally define a structure
在使用基于控制台的程序时，我倾向于使用getopt()或getopt_long来分析命令行参数。 但是，大多数情况下，我最终使用全局变量来存储我可以在所有*.c文件中使用的配置参数。 所以我很想知道你使用了什么样的模式，以及什么样的模式更适合全局变量。 我通常定义一个结构： struct ConfigurationOpts { int interval; int fullscreen; /* ... */ }; 并将一个指向struct ConfigurationOpts的实例的指针传递给其他
I have a single string that contains the command-line parameters to be passed to another executable and I need to extract the string[] containing the individual parameters in the same way that C# would if the commands had been specified on the command-line. The string[] will be used when executing another assemblies entry-point via reflection. Is there a standard function for this? Or is ther
我有一个包含要传递给另一个可执行文件的命令行参数的单个字符串，并且需要以与C＃中命令相同的方式提取包含各个参数的字符串[]，如果命令已在命令行上指定。 当通过反射执行另一个组件入口点时，将使用字符串[]。 有这个标准功能吗？ 还是有一个首选的方法（正则表达式？）正确分裂参数？ 它必须处理可能正确包含空格的'''分隔字符串，所以我不能仅仅分割''。 示例字符串： string parameterString

I am trying to figure out when and why to use a Dictionary or a HashTable. I have done a bit of a search on here and have found people talking about the generic advantages of the Dictionary which I totally agree with, which leads the boxing and unboxing advantage for a slight performance gain. But I have also read the Dictionary will not always return the objects in the order they are inserted
我想弄清楚何时以及为什么要使用Dictionary或HashTable。 我在这里做了一些搜索，发现人们在谈论字典的通用优势，我完全同意这种看法，这会带来拳击和拆箱优势，从而获得轻微的性能提升。 但是我也读过字典并不总是按照它们插入的顺序返回对象，它对它进行排序。 作为HashTable将在哪里。 据我所知，这导致HashTable在某些情况下要快得多。 我的问题是，这些情况会是什么？ 我在上面的假设中错了吗？ 你可以用什么情况
