小编sw2*_*020的帖子

我试图将两个值加在一起,例如14.0 + 2.1 = 16.1但我继续将它们相加,例如14.0 + 2.1 = 14.02.1

var miledistance = miledistance1 + miledistance2;

当我尝试连接到一个不存在的实例时,UI在我的应用程序中锁定我尝试使用新线程,但这似乎不起作用

//从主类打电话

 Dispatcher.BeginInvoke(new Action(
 () => Timedtask(instance, database)));    

 //Method

  public void Timedtask(string instance, string database)
        { 
            Timer.Start();
            Timer.Tick += delegate
            {
                if (!TimedTask.timer_Tick(instance, database))
                {
                    Dispatcher.CurrentDispatcher.Invoke(Stopped);
                }
            };

        }   

    // Try an open connection

         using (var con1 = new SqlConnection
                {
                    ConnectionString = @"Data Source=" + instanceName1 + ";Integrated Security=SSPI;" +
                 "MultipleActiveResultSets=true;"
                })


                {

                //more code
                 con1.Open();               
                //more code
                }

我想在填充后从数据集中选择一个特定的列（例如列等级）并将值放入列表中

string excelFile = @"C:\Scores.xlsx";
if (File.Exists(excelFile))
{
    string connString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source="+excelFile+";Extended Properties=Excel 12.0;";
    var dataAdapter = new OleDbDataAdapter();
    var objConn = new OleDbConnection(connString);

    //SELECT [Name],[Grade],[Location] ect...
    const string query = "SELECT * FROM [TeamScores$]"; 
    var objCmd = new OleDbCommand(query, objConn);

    var table = new DataSet();
    dataAdapter.SelectCommand = objCmd;
    dataAdapter.Fill(table);               

    //I would like to filter the DataSet to select only [Name] and populate the values into a List<string>

    dataGridView1.DataSource = table.Tables[0]; //Will show all results                

}

我正在努力解决如何将javascript中生成的值添加到php页面,以便将结果发送一封电子邮件.

function sendmemail(){

        var data = 'result=' + result.val();

$.ajax({

            url: "process.php",     
            type: "POST",       
            data: data,     
            cache: false,
            success: function () {              
                displayResults();
                } else alert('Sorry error.');               
            });     
        }
