一。首先在模块中添加如下代码。
对象类型是DAO/ADO
============
对 DAO 定义
dim wkData as dao.workspace
Dim dbData as dao.Database
============
对ADO定义
dim cnn as new connection
二。在模块中创建如下过程
Option Explicit
'* 使用DAO打开带密码数据库
Sub OpendatabaseWithPassword(DB As Object, strDatabase As String, strPass As String)
Set DB = DBEngine.OpenDatabase(App.Path & "\" & strDatabase, False, False, ";pwd=" & strPass)
End Sub
'* 使用ADO打开带密码数据库
Sub OpenConnectionWithPassword(DB As Object, strProvider, strDataSource As String, strPassWord As String)
DB.Open _
strProvider & _
strDataSource & _
strPassWord
End Sub
'* 使用DAO修改数据库密码
Sub ChangeDBPassword_DAO(DB As Object, strDatabase As String, strOldPass As String, strNewPass As String)
Set DB = DBEngine.OpenDatabase(App.Path & "\" & strDatabase, True, False, ";pwd=" & strOldPass)
DB.NewPassword strOldPass, strNewPass
DB.Close
End Sub
'* 使用DAO修改用户密码
Sub ChangeUserPassword_DAO(DB As Object, strOldPass As String, strNewPass As String)
DBEngine.SystemDB = "c:\win98\system\system.mdw"
Set DB = DBEngine.CreateWorkspace("", "Admin", strOldPass)
DB.Users("Admin").NewPassword strOldPass, strNewPass
DB.Close
End Sub
'* 使用ADO修改用户密码
'* Assumes that the Admin user doesn't currently have a password set
'* Provider=Microsoft.Jet.OLEDB.4.0;
Sub ChangeUserPassword_ADO(DB As Object, strProvider, strDataSource As String, strSystem As String, strOldPassword As String, strNewPassword As String)
DB.ActiveConnection = _
strProvider & _
strDataSource & _
strSystem
DB.Users("Admin").ChangePassword strOldPassword, strNewPassword
Set DB = Nothing
End Sub
'* 使用DAO添加新用户 组 密码
Sub CreateUserGroup_DAO(DB As Object, User As Object, NewUser As String, strPID As String, strPassWord As String, wrkPass As String)
DBEngine.SystemDB = "c:\win98\system\system.mdw"
Set DB = DBEngine.CreateWorkspace("", "Admin", wrkPass)
Set User = DB.CreateUser(NewUser, strPID, strPassWord)
DB.Users.Append User
DB.Close
End Sub
'* 添加新用户到组 -tmtony
Sub AddUserToGroup(DB As Object, strPass As String, strNewUser As String, strNewGroup)
DBEngine.SystemDB = "c:\win98\system\system.mdw"
Set DB = DBEngine.CreateWorkspace("", "Admin", strPass)
DB.Users(strNewUser).Groups.Append _
DB.Users(strNewUser).CreateGroup(strNewGroup)
DB.Close
End Sub
三。使用方法
OpenDatabaseWithPassWord(dbData, "Test.mdb", "vbcode")
OpenConnectionWithPassWord(cnn,"Provider=Microsoft.Jet.OLEDB.4.0;","Data Source=" + app.path + "\"+ "Test.mdb","vbcode")
