Dim a!, b!, c!
Dim l(1 To 5)  As Single
Dim h(1 To 5)  As Single
Dim Ls(1 To 5) As Single
Adodc1.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=F:\电影\Database13.mdb;Persist Security Info=False"
= adCmdUnknown
Adodc1.RecordSource = "select * from 表1"
Adodc1.Refresh
For a = 1 To 5
   l(a) = Val(Adodc1.Recordset.Fields(1))
   Adodc1.Recordset.MoveNext
Next a
For a = 1 To 5
   h(a) = Val(Adodc1.Recordset.Fields(2))
   Adodc1.Recordset.MoveNext
Next a
c = 1
Do While c < 6
  Ls(c) = h(c) + l(c)
  Label1.Caption = Label1.Caption & Ls(c) & vbCrLf
  c = c + 1
Loop
End Sub

出现上述错误代码，主要是这段代码
Adodc1.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=F:\电影\Database13.mdb;Persist Security Info=False"
= adCmdUnknown
Adodc1.RecordSource = "select * from 表1"
Adodc1.Refresh

connection对象和recordset对象没执行open方法打开，当然没有记录
