这代码需要改吗？ 不是用的 ADODB.Connection 和 ADODB.RecordSet 吗？

可以了，问题已经解决了
Dim cn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim sql1 As String
Dim sql2 As String
cn.ConnectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=MZJJSFXT;Data Source=."
cn.Open
sql1 = "select 结算方式 as 收款方式,count(收据号)as 收据数,sum(总金额)as 金额 from 收费单据信息表 where 操作员='" + Txtsky.Text + "'and 收据号 between '" + Txtsjn1.Text + "'And '" + Txtsjn2.Text + "'group by 结算方式"
If rs.State = adStateOpen Then rs.Close
rs.CursorLocation = adUseClient
rs.Open sql1, cn, adOpenKeyset, adLockOptimistic
With rs
If rs.RecordCount > 0 Then
Do While rs.EOF = False
