I have downloaded Privoxy few weeks ago and for the fun I was curious to know how a simple version of it can be done. I understand that I need to configure the browser (client) to send request to the proxy. The proxy send the request to the web (let say it's a http proxy). The proxy will receive the answer... but how can the proxy send back the request to the browser (client)? I have se
我已经在几周前下载了Privoxy,为了好玩,我很想知道它的简单版本是如何完成的。 我知道我需要配置浏览器(客户端)向代理发送请求。 代理将请求发送给Web(假设它是一个http代理)。 代理将收到答案...但代理如何将请求发送回浏览器(客户端)? 我在网上搜索了C#和http代理,但没有找到让我了解它在场景后面如何正确工作的内容。 (我相信我不想要反向代理,但我不确定)。 你们有没有一些解释或一些信息让我继续这
Sleep() is very accurate, so for example if I want to sleep for 10 hours: Sleep(36000000); // sleep for 10 hours My thread will wait for exactly 10 hours (plus the time that Windows needs to wake up my thread, which is negligible). However, since Sleep() will block my UI thread, I which to use Windows Timers instead. So is a Windows Timer as accurate as Sleep() ? that is, will it wait for e
Sleep()是非常准确的,所以例如,如果我想睡10个小时: Sleep(36000000); // sleep for 10 hours 我的线程将等待10个小时(加上Windows需要唤醒我的线程的时间,这可以忽略不计)。 但是,由于Sleep()会阻塞我的UI线程,所以我使用Windows定时器。 那么Windows计时器是否与Sleep()一样精确? 也就是说,它会等待10个小时(加上我的窗口过程接收WM_TIMER消息所需的时间)吗? 是的, Sleep()和SetTimer()下面的基本管道是
I'm looking for a website that offers API for retrieving the words from English WordNet database. I do not want to download the WordNet database and implement it in my server. Simply I want to call API and get back some results in XML format from that web site. I have a web application in ASP.net that is written in C#. Here there is a sample from WordNet, I want to do something like th
我正在寻找一个提供API来检索英文WordNet数据库中的单词的网站。 我不想下载WordNet数据库并在我的服务器中实现它。 简单地说,我想调用API并从该网站获取XML格式的一些结果。 我在ASP.net中有一个用C#编写的Web应用程序。 这里有一个来自WordNet的示例,我想在我的web应用程序中做类似的事情。 WordNet Online 看来,这是不公开的API。 根据Related Projects站点,WordNet数据的一部分可通过abbreviations.com以A
I am writing an analysis application in C# that has to deal with a lot of memory. I use ANTS Memory Profiler 7.4 for optimizing my memory management. While doing so, I realized that all of my double[,] arrays I use (and i need them) are placed on the LOH although the largest of these arrays is about 24.000 bytes. Objects should not be put there before 85.000 bytes as far as I know. The proble
我正在用C#编写一个分析应用程序,它必须处理大量内存。 我使用ANTS Memory Profiler 7.4来优化我的内存管理。 虽然这样做,我意识到我使用的所有double [,]数组(尽管这些数组中的最大值是大约24.000字节)放在LOH上。 就我所知,对象不应该放在85.000字节之前。 现在的问题是,由于我有大约数千个这样的double [,]数组实例,因此我有很多内存碎片(我的总内存使用量的大约25%是我无法使用的可用内存)。 存储在LOH中
In C# how can I copy a file from a camera to my local drive? The camera is connected via USB and it does not show up as a standard drive. I am using a Sony Handycam HDR-CX160. I want to write a small c# windowsform app that copies the video files from the device. So how does my app copy files from the device connected via usb? It does not show up as a drive but it shows up in windows explo
在C#中,我如何将文件从相机复制到本地驱动器? 相机通过USB连接,不会显示为标准驱动器。 我正在使用Sony Handycam HDR-CX160。 我想写一个小型的c#windowsform应用程序,从设备复制视频文件。 那么我的应用程序如何从通过USB连接的设备上复制文件? 它不会显示为驱动器,但会显示在Windows资源管理器中。 当我在C#中搜索驱动器时,它不在列表中? 谢谢! ======== UPDATE ======= 我会尝试以不同的方式提出这
We are using .NET4.5 , SQL2012 and FluentMigrator to control our database migrations. We are running multiple databases in our solution and we need to run some data inserts into some databases but not the others. How can I run some database migrations based on specific database name? I have introduced this class that controls which databases it should run on. So rather when inheriting from
我们使用.NET4.5 , SQL2012和FluentMigrator来控制我们的数据库迁移。 我们在解决方案中运行多个数据库,我们需要将一些数据插入到一些数据库中,而不是其他数据库中。 我如何根据特定的数据库名称运行一些数据库迁移? 我已经引入了这个类来控制它应该运行的数据库。 所以,当从Migration继承时,您现在将从OnlyRunOnSpecificDatabaseMigration继承: 一个注意!:如果DatabaseNamesToRunMigrationOnList中没有列出任
Assume that I have a DataGridView which is populated by a number of different strings (different length, numbers and plain text) in Cells. Want I want to do is to copy and paste these strings, which could be any selection of Cells. My approach to copy is: if (e.Control && e.KeyCode == Keys.C) { // copy DataGridViewSelectedCellCollection tmpCells = this.MyDataGridView.Selected
假设我有一个DataGridView ,它由Cells中的许多不同的strings (不同的长度,数字和纯文本)填充。 我想要做的是复制和粘贴这些字符串,这可能是任何选择的单元格。 我的复制方法是: if (e.Control && e.KeyCode == Keys.C) { // copy DataGridViewSelectedCellCollection tmpCells = this.MyDataGridView.SelectedCells; Clipboard.SetDataObject(tmpCells); } 哪个工作正常。 我的粘贴方法是:
I would like to copy a region of cells from a dataGridView and then paste that data into MS Excel. I am able to copy data and paste into MS Word or Notepad but not excel. There are lots of examples of copying from Excel and Pasting into a DataGridView but not the other way around. private void frm_KeyDown(object sender, KeyEventArgs e) { if (e.Control && e.KeyCode == Keys.C) {
我想复制dataGridView中的单元格区域,然后将该数据粘贴到MS Excel中。 我能够复制数据并粘贴到MS Word或记事本中,但不是Excel。 有很多从Excel复制和粘贴到DataGridView但不是相反的例子。 private void frm_KeyDown(object sender, KeyEventArgs e) { if (e.Control && e.KeyCode == Keys.C) { this.dataGridView1.ClipboardCopyMode = DataGridViewClipboardCopyMode.EnableWithoutHeaderText;
