Private Sub Form_Load()
    Dim rst As ADODB.Recordset
    Dim strItem As String
    '初始化ComboBox
    SQL = " select 用户ID,用户名称 from 用户信息表 order by 用户ID"
    Set rst = SelectSQL(SQL, msg)
    If rst.RecordCount > 0 Then
        Do While Not rst.EOF
        strItem = rst.Fields(0) & " " & rst.Fields(1)
        CboName.AddItem (strItem)
        rst.MoveNext
        Loop
        rst.Close
        CboName.ListIndex = 0
    Else
        MsgBox ("请先创建用户信息！")
        CmdOK.Enabled = False
        Exit Sub
    End If
End Sub
运行到If rst.RecordCount > 0 Then出现提示vb 实时错误‘91’对象变量或 With 块变量没有设置
望解决，不胜感激
