问:如果我有两个这样的DataTable:

DT1(emp_num,emp_name,type)

DT2(emp_num,emp_name,type)

我想联盟他们并订购结果emp_name.

我在DataTable中有非规范化数据.

数据包含员工姓名,以及他们在一系列薪资周期中获得的薪酬.即:

我的DataTable包含:

Employee 1    Jan-1-2012     $100
Employee 2    Jan-1-2012     $300
Employee 1    Feb-1-2012     $400
Employee 2    Feb-1-2012     $200
Employee 1    Mar-1-2012     $150
Employee 2    Mar-1-2012     $325

如何将此数据加载到父DataTable包含员工姓名的DataSet中,子DataTable包含薪水检查的详细信息？

我已经成功实现了Ignited-Datatables.但是,在输入数据库时​​,输入"非拉丁"字符,如"İ,ş,ğ,.."

POST http://vproject.dev/module/user/ign_listing 500 (Internal Server Error)

细节是:

Illegal mix of collations for operation 'like' while searching
... (u.id_user LIKE '%Ä°%' OR u.first_name LIKE '%Ä°%' OR u.last_name LIKE '%Ä°%' OR ue.email LIKE '%Ä°%' OR u.last_login LIKE '%Ä°%' ) ...

%Ä°% 部分根据您输入的非拉丁字符而变化.

有什么想法解决这个问题？

我缩小了图像,缩小了缩放到图像的原始大小.当图像处于缩小状态时,图像质量非常差.有什么方法可以改善吗？

(这是一个jsfiddle:https://jsfiddle.net/w9o2chmn/7/ )

$(document).ready(function() {
    var zoomed = false;
    var card = $("#card0");
    card.click(function() {
        zoomFunction();
    });

    function zoomFunction() {
        if (zoomed) { //card flipped so front is invisible and back is visible. 
            zoomed = false;
            card.removeClass('zoom');
        } else { //card not flipped so front is visible and back is invisible
            zoomed = true;
            card.addClass('zoom');
        }
    };
});

html {height: 100%;}
.zoom {transform: scale(1.0);}
img {
  transform: scale(0.5);
  transform-style: preserve-3d;
  transition: 1s;
}

<img id="card0"  src="http://valtterilaine.bitbucket.org/png/vihainen.png">

我有一个ASP.NET MVC网站,它有一个下拉列表,在视图中使用它创建...

@Html.DropDownList("Programs")

程序从Business Object集合填充,并填充到Home Controller上的索引操作中的ViewBag中......

\\get items...
ViewBag.Programs = items;

该视图还有三个我在同一视图中得到的文件...

<input type="file" name="files" id="txtUploadPlayer" size="40" />  
<input type="file" name="files" id="txtUploadCoaches" size="40" />  
<input type="file" name="files" id="txtUploadVolunteers" size="40" /> 

所有上述控件都包含在使用...在视图中创建的表单中

@using (Html.BeginForm("Index", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
     <!--  file and other input types  -->
     <input type="submit" name="btnSubmit" value="Import Data" />
}

我的问题是我找不到处理所有文件的方法并引用表单字段.

具体来说,我需要知道用户从下拉菜单中选择的程序.

我可以使用这段代码处理文件没有问题...

[HttpPost]
public ActionResult Index(IEnumerable<HttpPostedFileBase> files)
//public ActionResult Index(FormCollection form)
{

    _tmpFilePath = Server.MapPath("~/App_Data/uploads");

    if (files == null) return RedirectToAction("Index");
    foreach (var …

我有一个3层架构并使用tcp套接字在传输层(TCP客户端)中发送一些数据这种方法是使用BeginSend方法异步的.

public void TransportData(Stream stream)
{
    try
    {
        SetTransporterState(StateObject.State.SendingData);
        if (clientSock.Connected)
        {
            ASCIIEncoding asen = new ASCIIEncoding();
            stream.Position = 0;
            byte[] ba = GetStreamAsByteArray(stream);
           if (clientSock.Connected)
              clientSock.BeginSend(ba, 0, ba.Length, SocketFlags.None, new AyncCallback(SendData), clientSock);
           else
               throw new SockCommunicationException("Socket communication failed");

         }
         catch (SocketException sex)
         {
             throw sex;
         }
         catch (SockCommunicationException comex)
         {
             bool rethrow = ExceptionPolicy.HandleException(comex, "TransportLayerPolicy");
         if (rethrow)
         {
             throw;
         }
       }
     }
   }
   catch (SocketException soex)
   {
     throw soex;
   }
   catch (SockCommunicationException comex)
   {
      bool rethrow = ExceptionPolicy.HandleException(comex, "TransportLayerPolicy"); …

有没有办法做到这一点？

//Example function taking in first and last name and returning the last name.
public void lastNameGenerator() throws Exception{
    try {
        String fullName = JOptionPane.showInputDialog("Enter your full name");
        String lastName = fullName.split("\\s+")[1];
    catch (IOException e) {
        System.out.println("Sorry, please enter your full name separated by a space.")
        //Repeat try statement. ie. Ask user for a new string?
    }
    System.out.println(lastName);

我想我可以使用扫描仪代替这一点,但我很好奇是否有办法在捕获异常后重复try语句.

我有一个MVC4应用程序Windows Authentication.用户可以键入10个视图中的任何一个的url来加载应用程序.没有特定的主页

如果用户闲置超过一分钟,我需要重定向到会话超时视图.我将配置文件中的会话超时值保持为一分钟.我创建了一个action filter检查一个特定会话值的方法.此特定会话值设置Session_Start为Global.asax.

但是,当超时时间结束时,请求再次命中Session_Start并且它正在分配值.因此我的动作过滤器不会重定向到错误视图.有什么可能的解决方案来解决这个问题？

Web.Config中

<system.web>
    <!--Impersonate-->
    <identity impersonate="true"/>
        <!--Session Mode and Timeout-->
    <sessionState mode="InProc" timeout="1" />
    <authentication mode="Windows">
    </authentication>
    <authorization>
      <allow users="?" />
    </authorization>    
</system.web>

动作过滤器

[AttributeUsage(AttributeTargets.Method, Inherited = true, AllowMultiple = false)]
public class SessionCheckAttribute : ActionFilterAttribute
{
    public override void OnActionExecuting(System.Web.Mvc.ActionExecutingContext filterContext)
    {
        string controllerName = filterContext.ActionDescriptor.ControllerDescriptor.ControllerName.ToLower();
        HttpSessionStateBase session = filterContext.HttpContext.Session;
        var activeSession = session["IsActiveSession"];
        if (activeSession == null)
        {
            //Redirect
            var url = new UrlHelper(filterContext.RequestContext); …

我正在尝试使用Except方法比较两个列表,但它无法正常工作:

List<Customer> PotentialSharedCustomer = new List<Customer>();
PotentialSharedCustomer.Add(new Customer { AccountId = Guid.Empty, AccountNumber = "01234", Name = "Hans Jürgen" });
PotentialSharedCustomer.Add(new Customer { AccountId = Guid.Empty, AccountNumber = "05465", Name = "Beate Müller" });
PotentialSharedCustomer.Add(new Customer { AccountId = Guid.Empty, AccountNumber = "15645", Name = "Sabine Meyer" });
PotentialSharedCustomer.Add(new Customer { AccountId = Guid.Empty, AccountNumber = "54654", Name = "Moritz Kummerfeld" });
PotentialSharedCustomer.Add(new Customer { AccountId = Guid.Empty, AccountNumber = "15647", Name = "Hanna Testname" });

List<Customer> ActualSharedCustomer = new …

我试图得到一个看起来像一个规格的图表.

我已经在我的其他图表中使用jQuery Flot,所以可以使用Flot或纯Javascript吗？有人可以帮我开始编码吗？
