I've asked a couple of questions here but am still having issues. I'd appreciate if you could tell me what I am doing wrong in my code. I run the code above from a ASP.Net page and get "Cannot Access a Closed Stream". var doc = new Document(); MemoryStream memoryStream = new MemoryStream(); PdfWriter.GetInstance(doc, memoryStream); doc.Open(); doc.Add(new Paragraph("First P
我在这里问了几个问题,但仍然有问题。 如果你能告诉我我的代码中我做错了什么,我将不胜感激。 我从ASP.Net页面运行上面的代码,并得到“无法访问封闭的流”。 var doc = new Document(); MemoryStream memoryStream = new MemoryStream(); PdfWriter.GetInstance(doc, memoryStream); doc.Open(); doc.Add(new Paragraph("First Paragraph")); doc.Add(new Paragraph("Second Paragraph")); doc.Close(); //if I remove thi
We have a dynamic languaging system that doesn't use conventional resource files; fetching resources from a database, via a language manager library instead. Based on a legacy (VB6) solution, it languages controls according to the resource name in the control's tag property. After the page has initialised we fire off a method that takes LayoutRoot and recurses it's children applyin
我们有一个不使用传统资源文件的动态语言系统; 而是通过语言管理器库从数据库获取资源。 基于传统(VB6)解决方案,它的语言根据控件的标签属性中的资源名称进行控制。 在页面初始化之后,我们引发一个采用LayoutRoot的方法,并递归它的子应用字符串的控件从标签中查找字符串。 这被证明是笨拙的,递归例程变成了怪物来迎合不同控件的微妙之处,我想改为使用数据绑定来应用字符串。 我意识到我可以声明属性来绑定到每个控
Is there anyone with a working piece of sample C code that implements LiveView using the Canon EDSDK? The sample code in the documentation looks great until you get to this bit: // // Display image // Yup, that's it. They don't show how to BLT an image to a window using the data retrieved from the camera. They just say, "Display image." Thanks, Canon. I have hunted th
是否有任何人使用Canon EDSDK实现LiveView的示例C代码工作片? 文档中的示例代码看起来很棒,直到您找到这个位: // // Display image // 是的,就是这样。 他们没有说明如何使用从相机检索到的数据将图像BLT到窗口。 他们只是说,“显示图像”。 谢谢,佳能。 我已经搜寻了互联网(包括这个论坛),但我还没有找到一个C代码示例,说明如何做到这一点。 我正在寻找避免MFC,VB,托管代码或C#。 肯定有可能在香草C中
how we used data validation on asp.net? date can't be insert greater than the current date. Use a CompareValidator. Most people use this for comparing two values entered into two textboxes, but you can also use it to compare one entered value with a set value as in your case. <asp:CompareValidator id="Compare1" ControlToValidate="TextBox1" Type="Date" runat="se
我们如何在asp.net上使用数据验证? 日期不能大于当前日期。 使用CompareValidator。 大多数人使用它来比较输入到两个文本框中的两个值,但也可以用它来比较一个输入值和一个设置值,就像你的情况一样。 <asp:CompareValidator id="Compare1" ControlToValidate="TextBox1" Type="Date" runat="server"/> 在后面的代码中设置Compare1.ValueToCompare = new DateTime(...); 和Compare1.Oper
I've recently added WEB API to an existing VS desktop application and everything worked fine, until yesterday when I had to add a GET method that took three parameters, one of them a Date. Well, at first I thought that that was going to be a piece of cake, but much to my surprise I noticed that when I sent 2014/07/09 (9th July) on the server where the application was installed it was treated
我最近添加了WEB API到现有的VS桌面应用程序,并且一切正常,直到昨天我必须添加一个带有三个参数的GET方法,其中一个是Date。 那么,起初我认为这将是一小块蛋糕,但我很惊讶,我注意到,当我在安装应用程序的服务器上发送2014/07/09(7月9日)时,它被视为2014年/ 09/07(9月7日),所以我所有的比较从未奏效。 我尝试过从GET方法更改为POST方法,在服务器上将区域和语言选项设置更改为相同,将日期作为字符串传递,并使用
We want to show some JSON to a user who is testing our application. So we call our REST service in the ASP.NET code behind file and return a string, which holds a lot of JSON. We then put it in a PRE element in the page, call beautify to create nice readable JSON and all is good: sort of human readable content is shown. Good but for one thing: all the dates are shown in the normal JSON forma
我们想向正在测试我们的应用程序的用户展示一些JSON。 所以我们在ASP.NET代码后面的文件中调用我们的REST服务,并返回一个字符串,它包含很多JSON。 然后,我们将它放在页面中的PRE元素中,调用美化来创建可读的JSON,并且都很好:显示了一些可读的内容。 好,但有一件事:所有日期都以正常的JSON格式显示,如“/ Date(1319266795390 + 0800)/” 我想要做的是在JSON(C#)字符串中用'普通'日期替换那些JSON日期
This question already has an answer here: The “right” JSON date format 10 answers See the Stack Overflow question Format a Microsoft JSON date?: var date = new Date(parseInt(jsonDate.substr(6))); Stack Overflow question The "right" JSON date format is more specific and direct to your question. It's auto-conversion: 2013-01-09 02:18:11.117 = "/Date(1357690691117)/"

If you serialize and deserialize a DateTime using embedded .net JavaScriptSerializer, you get two different dates if you are in UTC+something ! Example (suppose you are in UTC+2 like I am now) JavaScriptSerializer myJson = new JavaScriptSerializer(); DateTime myDate = DateTime.Now; //suppose 2016-03-29 16:12:00 strSerialized = myJson.Serialize(myDate); //DO WHAT YOU NEED WITH IT... DateTime
如果使用嵌入式.net JavaScriptSerializer对DateTime进行序列化和反序列化,如果使用UTC +,则会得到两个不同的日期! 例子(假设你现在在UTC + 2中) JavaScriptSerializer myJson = new JavaScriptSerializer(); DateTime myDate = DateTime.Now; //suppose 2016-03-29 16:12:00 strSerialized = myJson.Serialize(myDate); //DO WHAT YOU NEED WITH IT... DateTime myDateDes = myJson.Deserialize<DateTime>(strS
Isn't there a (simple) way to tell Linq To SQL classes that a particular DateTime property should be considered as UTC (ie having the Kind property of the DateTime type to be Utc by default), or is there a 'clean' workaround? The time zone on my app-server is not the same as the SQL 2005 Server (cannot change any), and none is UTC. When I persist a property of type DateTime to the
是不是有一种(简单)的方法来告诉Linq To SQL类,一个特定的DateTime属性应该被认为是UTC(即默认情况下,将DateTime类型的Kind属性设置为Utc),还是有一个“干净的”解决方法? 我的应用程序服务器上的时区与SQL 2005 Server不同(不能更改任何内容),且没有一个是UTC。 当我将DateTime类型的属性保存到dB时,我使用UTC值(因此db列中的值是UTC),但是当我读取值(使用Linq To SQL)时,我得到DateTime的.Kind属性值为'
