小编Luc*_*tos的帖子

我想知道该import陈述是如何运作的.

我问这个是因为我的imports项目中有以下内容:

import static com.googlecode.javacv.jna.highgui.cvCreateCameraCapture;
import static com.googlecode.javacv.jna.highgui.cvGrabFrame;
import static com.googlecode.javacv.jna.highgui.cvReleaseCapture;
import com.googlecode.javacv.CanvasFrame;
import com.googlecode.javacv.FrameGrabber;
import com.colorfulwolf.webcamapplet.gui.ImagePanel;
import com.googlecode.javacv.OpenCVFrameGrabber;
import com.googlecode.javacv.jna.cxcore.IplImage;

我的项目中没有这些软件包,那么,这将如何导入？

如果我用我的所有类创建一个JAR文件,我的服务器将托管这个JAR文件,必须是免费的Internet访问才能获得这些文件package吗？

我有一些问题,我Applet有这些进口,我问这个问题,了解是否可以成为互联网规则.

我在我的解决方案中创建了一个MVC 4 Web API应用程序,但我现在收到2个错误,我需要一些帮助.

'System.Web.Http.HttpConfiguration'不包含'MapHttpAttributeRoutes'的定义,也没有扩展方法'MapHttpAttributeRoutes'接受类型为'System.Web.Http.HttpConfiguration'的第一个参数'(你是否缺少using指令)或汇编参考？)

以下代码发生此错误

文件:WebApiConfig.cs(在App_Start文件夹中)

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Http;
using System.Web;

    public static class WebApiConfig
    {
        public static void Register(HttpConfiguration config)
        {
            // Web API configuration and services

            // Web API routes
            config.MapHttpAttributeRoutes();

            config.Routes.MapHttpRoute(
                name: "DefaultApi",
                routeTemplate: "api/{controller}/{id}",
                defaults: new { id = RouteParameter.Optional }
            );
        }
    }

另一个是Global.asax

'System.Web.Http.GlobalConfiguration'不包含'Configure'的定义

文件:Global.asax.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Http;
using System.Web.Http.WebHost;
using System.Web.Mvc;

using System.Web.Routing;

如何通过OpenXml更改文档的字体系列？我尝试了一些方法但是,当我打开文档时,它总是在Calibri中

按照我的代码,我尝试了.

我认为Header Builder无用于发布

private static void BuildDocument(string fileName, List<string> lista, string tipo)
{                
    using (var w = WordprocessingDocument.Create(fileName, WordprocessingDocumentType.Document))
    {
        var mp = w.AddMainDocumentPart();
        var d = new DocumentFormat.OpenXml.Wordprocessing.Document();
        var b = new Body();
        var p = new DocumentFormat.OpenXml.Wordprocessing.Paragraph();
        var r = new Run();

        // Get and format the text.                                    
        for (int i = 0; i < lista.Count; i++)
        {
            Text t = new Text();                    
            t.Text = lista[i];
            if (t.Text == "          ")
            {
                r.Append(new CarriageReturn());
            }
            else
            { …

如果某些列返回FALSE,如何显示不同的值,

例如,

COLUMN"BASIC"返回FALSE,但我需要为用户显示YES或NO.情况FALSE,返回NO.

当我把glyphicons.css我的BundleConfig中调用的特定CSS文件发生以下错误时

An exception of type 'System.IndexOutOfRangeException' occurred in WebGrease.dll but was not handled in user code

并且该文件存在于我的解决方案中的特定路径中,就像所有其他CSS文件一样.

有人遇到过这个问题吗？

    bundles.Add(new StyleBundle("~/Content/css").Include(
                "~/Content/css/bootstrap.css",
                "~/Content/css/uploadfyBoot/style.css",
                "~/Content/css/uploadfyBoot/jquery.fileupload.css",
                "~/Content/css/tipografia.css",
                "~/Content/css/glyphicons.css"
                ));

如果我删除对glyphicons.css的引用它可以工作.

我正在尝试在我的Angular应用程序中使用Jasmine进行一些单元测试,但我遇到了一些错误.

错误

Error: [$injector:modulerr] Failed to instantiate module LocalStorageModule due to:
Error: [ng:areq] Argument 'fn' is not a function, got string

规格

describe("testing the controller", function () {

   var $controllerConstructor;
   var scope;

   beforeEach(module('app', ['ngRoute', 'LocalStorageModule']));
   beforeEach(inject(function ($controller, $rootScope) {
       $controllerConstructor = $controller;
       scope = $rootScope.$new();
   }));

   it("should validate a contact", function () {
       var ctrl = $controllerConstructor('crmContatosCtrl', { $scope: scope });
   });
});

App.js

angular
    .module('app', ['ngRoute', 'LocalStorageModule'])
    .config(['$routeProvider', '$locationProvider', function ($routeProvider, $locationProvider) {
       // My routeProvider here
    }]);

我还没有使用Yeoman和Karma,因为这是我使用Angular的fisrt应用程序. …

我怎么能这样做query用LINQ and LAMBDA？

QUERY

Select san_negocio.imovel_id
      ,san_negocio.negocio_id
      ,san_imovel.credenciada_id
      ,san_proposta.proposta_id
      ,san_proposta.credenciada_id
  from san_negocio
  join san_proposta
    on san_negocio.imovel_id = san_proposta.imovel_id
  join san_imovel
    on san_negocio.imovel_id = san_imovel.imovel_id
 where san_negocio.credenciadacaptadora_id is null
   and san_negocio.credenciadavendedora_id is null
   and san_proposta.statusproposta_id = 2

我试过了:

var objetos = db.San_Negocio.Join(db.San_Proposta, a => a.Imovel_Id, b => b.Imovel_Id, (a, b) => new { San_Negocio = a, San_Proposta = b })                
    .Join(db.San_Imovel, a => a.San_Negocio.Imovel_Id, c => c.Imovel_Id, (a, c) => new { San_Negocio = a, San_Imovel = …

我需要阅读所有的Child Nodes我的<Imovel>标签,问题是,我有超过1(一)<Imovel>在我的XML文件中的标记,每个之间的区别<Imovel>标签是所谓的ID属性.

这是一个例子

<Imoveis>
   <Imovel id="555">
      <DateImovel>2012-01-01 00:00:00.000</DateImovel>
      <Pictures>
          <Picture>
              <Path>hhhhh</Path>
          </Picture>
      </Pictures>
      // Here comes a lot of another tags
   </Imovel>
   <Imovel id="777">
      <DateImovel>2012-01-01 00:00:00.000</DateImovel>
      <Pictures>
          <Picture>
              <Path>tttt</Path>
          </Picture>
      </Pictures>
      // Here comes a lot of another tags
   </Imovel>
</Imoveis>

我需要阅读每个标签的所有<Imovel>标签,并且在我在<Imovel>标签中进行的每次验证结束时,我需要进行另一次验证.

所以,我认为我需要做2(2)foreach或a for和a foreach,我不太了解LINQ但是按照我的样本

XmlReader rdr = XmlReader.Create(file);
XDocument doc2 = XDocument.Load(rdr);
ValidaCampos valida = new ValidaCampos();

//// Here I Count …

我试图<!CDATA>在我的XML文件中放入一个特定的标签,但结果是<![CDATA[mystring]]>

有人可以帮帮我吗？

编码

XmlProcessingInstruction pi = doc.CreateProcessingInstruction("xml", "version=\"1.0\" encoding=\"utf-8\"");

我是怎么做的

texto.InnerText = "<![CDATA[" + elemento.TextoComplementar.ToString() + "]]>";

我正在尝试使用 Jasmine 进行单元测试并调用我的 Angular 5 服务，但出现以下错误

TypeError: this.dailySalesService.resetValues is not a function

调用changeDatein方法时会发生这种情况component.changeDate(new Date());。在changeDate我dailySalesService正确调用的方法内部，所以我认为我的组件中没有错误。
