帮我改错：Private Sub seek_Click() Dim mystyle As String Dim mycon As ADODB.Connection Set mycon = New ADODB.Connection mystyle = "学号" mycon.Open "dsn=mymy", "sa" Set myres1 = New ADODB.Recordset myres1.Open "select * from 班级情况 where " & mystyle & " = " & Text6.Text & "'", mycon, adOpenDynamic, adLockOptimistic If myres1.BOF And myres1.EOF Then Text1.Text = "" Text2.Text = "" Text3.Text = "" Text4.Text = "" Text5.Text = "" MsgBox "没有满足条件的记录！" Else Text1.Text = myres1.Fields(0) Text2.Text = myres1.Fields(1) Text3.Text = myres1.Fields(2) Text4.Text = myres1.Fields(3) Text5.Text = myres1.Fields(4) MsgBox "查询成功！" End If End Sub

您的代码中有一些错误，下面是改正后的代码：

Private Sub seek_Click()
    Dim mystyle As String
    Dim mycon As ADODB.Connection
    Dim myres1 As ADODB.Recordset '需要声明myres1变量

    Set mycon = New ADODB.Connection
    mystyle = "学号"
    mycon.Open "dsn=mymy", "sa"

    Set myres1 = New ADODB.Recordset
    myres1.Open "select * from 班级情况 where " & mystyle & " = '" & Text6.Text & "'", mycon, adOpenDynamic, adLockOptimistic

    If myres1.BOF And myres1.EOF Then
        Text1.Text = ""
        Text2.Text = ""
        Text3.Text = ""
        Text4.Text = ""
        Text5.Text = ""
        MsgBox "没有满足条件的记录！"
    Else
        Text1.Text = myres1.Fields(0)
        Text2.Text = myres1.Fields(1)
        Text3.Text = myres1.Fields(2)
        Text4.Text = myres1.Fields(3)
        Text5.Text = myres1.Fields(4)
        MsgBox "查询成功！"
    End If

    myres1.Close '关闭记录集
    mycon.Close '关闭连接
End Sub

改正的错误包括：

1. 没有声明 `myres1` 变量。
2. SQL 查询语句中的 `Text6.Text` 需要加上单引号。
3. 忘记关闭记录集和连接对象，应该在代码的最后加上 `myres1.Close` 和 `mycon.Close`。
