VB与数据库连接不上···老报错是:错误91 有没有人可以帮个忙看看啊？谢啦！！！
If rst.RecordCount > 0 Then --------------------编程问答-------------------- endif下面的完善中间 --------------------编程问答-------------------- 你的数据库连接代码在哪儿啊~~~~ --------------------编程问答-------------------- 代码在哪里~~~~~~~~~~~~~~~~~ --------------------编程问答--------------------
就这一行代码，还有不报错的可能吗？ --------------------编程问答-------------------- 完整的错误提示是不是这样：
实时错误91，“对象变量或with变量未设置”
搜索一下，可以找到很多的... --------------------编程问答-------------------- 代码在这边
Private Sub Form_Load()
Dim rst As New ADODB.Recordset
Dim SQL As String
Dim msg As String
Dim rights As String
Call GetConnStr
Conn.Open GetConnStr
OpenConn() = True
'查找权限
SQL = "select UPower from UI where UID='" & UID & "'"
Set rst = SelectSQL(SQL, msg)
If rst.RecordCount > 0 Then
rights = Trim(rst.Fields(0))
rst.Close
MsgBox ("没有用户信息！")
Else
Exit Sub
End If
就是报错 实时错误91，“对象变量或with变量未设置”
弄了半天还是连不上！！！ --------------------编程问答-------------------- Private Sub Form_Load()
Dim rst As New ADODB.Recordset
Dim SQL As String
Dim msg As String
Dim rights As String
'查找权限
SQL = "select UPower from UI where UID='" & UID & "'"
Set rst = SelectSQL(SQL, msg)
If rst.RecordCount > 0 Then
rights = Trim(rst.Fields(0))
rst.Close
MsgBox ("没有用户信息！")
Else
Exit Sub
End If
类模块的代码：
Public Function GetConnStr() As String
'得到数据库连接字符串，用户可以在此处设置连接字符串
'User ID是数据库用户ID,PassWord是登录密码
GetConnStr = "Provider=SQLOLEDB;User ID=sa;PassWord=123;Initial Catalog=人事管理系统:Data Source=LBWIN7"
End Function --------------------编程问答-------------------- Set rst = SelectSQL(SQL, msg)
SelectSQL，应该也是自己写的函数吧
--------------------编程问答-------------------- Set rst = SelectSQL(SQL, msg)
SelectSQL，应该也是自己写的函数吧
补充：VB , 基础类
