在IntelliJ IDEA Community Edition 14.0.2中,我正在尝试运行Java Applet,每次尝试运行项目时,都会遇到这个虚拟错误.

Error: Failed to create a child event loop

我试过的

1. 编译新创建的Hello World程序
2. 更新IntelliJ
3. 卸载并重新安装
4. 允许来自Windows防火墙规则
5. 禁用防病毒程序

我正在使用Windows 8.1反病毒程序Windows Defender.

我想在我的bootstrap中重复我的面板元素,for loop并mysubject在我的面板标题中显示我的变量.

例如.如果我的data.tickets.length == 4i应该有4个面板元素,每个面板都有不同的标题.你能帮助我吗？我不知道如何重复我的面板元素.到目前为止,我只是设置了标题.

这是我的代码:

HTML

<div class="col-xs-3 panel panel-default">
  <div class="panel-heading">
    <h3 class="panel-title"></h3>
  </div>
  <div class="panel-body">
    Panel content
  </div>
</div>

JS

function displaytickets(){
    var y = document.getElementById("mySecond").value;

    $.ajax({
      url: "https://cubber.zendesk.com/api/v2/users/"+y+"/tickets/requested.json",
      type: 'GET',
      dataType: 'json',
      contentType:'application/json',
      secure: true,
      beforeSend: function (xhr) {
          xhr.setRequestHeader("Authorization", "Basic " + btoa("claire.pagniez@cubber.com:"));
      },
      success: function (data) {
          console.log(data.tickets.length);
          for (i = 0; i < data.tickets.length; i++) {
              console.log(data.tickets[i]);

              console.log(data.tickets[i].description);
              console.log(data.tickets[i].status);
              console.log(data.tickets[i].subject);
              var mysubject = data.tickets[i].subject;

              $(".panel-title").append('<h3>'+mysubject+'</h3>');
          }
      }, …

我将使用C#中的OleDbDataAdapter在Access数据库中插入数据,但我在INSERT INTO命令中出现错误消息语法错误

BackgroundWorker worker = new BackgroundWorker();
OleDbDataAdapter dbAdapter new OleDbDataAdapter();
OleDbConnection dbConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=E:\\PMS.mdb");
worker = new BackgroundWorker();
worker.WorkerReportsProgress = true;
worker.DoWork += InsertJob;
worker.ProgressChanged += InsertJobCompleted;
worker.RunWorkerAsync(args);

而InsertJob函数是:

private void InsertJob(object sender, DoWorkEventArgs e)
{
     var args = (InsertJobArgs)e.Argument;
     try
        {
            dbAdapter.SelectCommand = new OleDbCommand("SELECT * FROM Sheet", dbConnection);                
            dbAdapter.Fill(args.DataTable);
            var builder = new OleDbCommandBuilder(dbAdapter);
            var row = args.DataTable.NewRow();

            row["UserName"] = args.Entry.UserName;
            row["Password"] = args.Entry.Password;
            args.DataTable.Rows.Add(row);

            dbAdapter.InsertCommand = builder.GetInsertCommand();               
            dbAdapter.Update(args.DataTable);
            builder.Dispose();
        }
        catch …
