我试图将文本设置为标签Label_caller.Text = phone_number,我收到此错误:"System.InvalidOperationException:跨线程操作无效:控件'Label_caller'从其创建的线程以外的线程访问." 我该如何克服这个问题？我如何使用关键字Me？

我有字符串数组列表:

"1A", "12A", "12B", "6", "A", "5B", "B", "13".

如果我这样做,myList.Sort();那么我得到:

"1A", "12A", "12B", "13", "5B", "6", "A", "B".

但我需要的是先按照前面的数字排序,然后按字母排序:

"1A", "5B", "6", "12A", "12B", "13", "A", "B".

我可以用

public class CustomComparer : IComparer
{
    Comparer _comparer = new Comparer(System.Globalization.CultureInfo.CurrentCulture);

    public int Compare(object x, object y)
    {
        // Convert string comparisons to int
        return _comparer.Compare(Convert.ToInt32(x), Convert.ToInt32(y));
    }
}

但它抛出异常.我如何得到我需要的东西？

在Oracle我有:

SELECT t2.Regkood, t2.naitatel, t2.naitafaks, t3.lahtiolekuaeg, t1.*
FROM table1 t1, table2 t2, table3 t3
WHERE t1.client = t2.client AND t1.client = t3.client(+) AND t1.client = 414246

如何在SQL Server中获得相同的内容？

谢谢

我正在使用此代码来获取数据:

 Dim connetionString As String
    Dim connection As SqlConnection
    Dim sqlq As String

    sqlq = "select top 1 * from table1 where smth"

    Dim ds As New DataSet
    connetionString = "Data Source=db;Initial Catalog=ic;User ID=id;Password=pass"
    connection = New SqlConnection(connetionString)

    Try
        Using connection
            Dim command As SqlCommand = New SqlCommand(sqlq, connection)
            connection.Open()
            Dim reader As SqlDataReader = command.ExecuteReader()
            If reader.HasRows Then
                Do While reader.Read()
                    x = reader.GetString(5)
                Loop
            End If
            reader.Close()
        End Using
    Catch ex As Exception
    End Try

这种类型的连接(与不同的sqlq [查询])我在diffenrent函数中使用了很多,每次我关闭连接.我想优化它,以便获取数据所需的时间更少.我怎么做？

如何使用带有HTML正文的MAPI发送邮件？我需要在消息正文中创建表。我正在使用vb6和MAPI控件。有任何想法吗？

Function MailSend(sSendTo As String, sSubject As String, sText As String) As Boolean
    On Error GoTo ErrHandler

    With MAPISession1
        If .SessionID = 0 Then
            .DownLoadMail = False
            .LogonUI = True
            .SignOn
            .NewSession = True
            MAPIMessages1.SessionID = .SessionID
        End If
    End With
    With MAPIMessages1
        .Compose
        .RecipAddress = sSendTo
        .AddressResolveUI = True
        .ResolveName
        .MsgSubject = sSubject
        .MsgNoteText = sText
        .Send False
    End With
    MailSend = True
    Exit Function
ErrHandler:
    'MsgBox Err.Description
    MailSend = False
End Function

我正在尝试使用 Jira REST API 包含组件来创建问题。我正在发布此 JSON，但我得到远程服务器返回错误：(400) 错误请求。

问题是：-没有组件就没有错误，但是当组件有问题时。有什么帮助吗？JSON：

{
  "fields": {
    "project": {
      "key": "keyGoesHere"
    },
    "assignee": {
      "name": "name.surname"
    },
    "component": {
      "name": "someName"
    },
    "summary": "test2",
    "description": "test2",
    "issuetype": {
      "name": "Task"
    }
  }
}
