|
|
|

Your question is not very clear at all. If you're looking to copy files, the System.Io namespace has what you're looking for, in the File, FileInfo, Directory, and DirectoryInfo classes. You'll find Copy methods on the File and FileInfo classes.

Yep, unless you mean File.Move("YourFilesCurrentPathAndName", "YourFilesNewLocationPathAndName")
My advice is free, and you may get what you paid for.

your answer will be a big help

I can't figure out how to add, edit and delete records in my database. whenever I try to add a new user to the database, this message comes out:
The 'Microsoft.Jet.OLEBD.4.0' provider is not registered on the local machine.
.ExecuteNonQuery() won't work..
I read that if your using datasets you don't need to use executeNonQuery.. But I don't know how to use datasets yet i have 'em..
this is the code i did for one adding records. PLease help me figure out what's wrong. I don't know if i have to change my settings on my pc or something's wrong with the code i did..
Imports System.Data.OleDb
Public Class frmUsers
Dim dbCon As New OleDbConnection("Provider = Microsoft.Jet.OLEBD.4.0; Data Source = dbCDNM.mdb")
Private Sub cmdAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAdd.Click
Dim s As String
dbCon.Open()
If optAdmin.Checked Then
s = "INSERT INTO Users(Username, Password, Lastname, Firstname, MI, Usertype) VALUES('" & txtUsername.Text & "', '" & txtPassword.Text & "', '" & txtLastname.Text & "', '" & txtFirstname.Text & "', '" & txtMI.Text & "', ' Administrator ')"
Dim dbCommand As New OleDbCommand(s, dbCon)
dbCommand.ExecuteNonQuery()
MessageBox.Show("Record Saved")
ElseIf optLib.Checked Then
s = "INSERT INTO Users(Username, Password, Lastname, Firstname, MI, Usertype) VALUES('" & txtUsername.Text & "', '" & txtPassword.Text & "', '" & txtLastname.Text & "', '" & txtFirstname.Text & "', '" & txtMI.Text & "', ' Librarian ')"
Dim dbCommand As New OleDbCommand(s, dbCon)
dbCommand.ExecuteNonQuery()
MessageBox.Show("Record Saved")
Else
MessageBox.Show("You have to select a user type.")
End If
dbCon.Close()
End Sub
End Class

Best guess, the Microsoft.Jet.OLEDB.4.0 provider is not registered on the local machine. Other possibilities that spring to mind is that the mdb is not in the same folder as your exe, or it needs a username/password, and .NET is giving you a useless error message.

Backup of what ? Your database ? Your source code ?

Sir,
I'm sorry sir for being not specific to my question. what I mean is files in my computer such as files save in drive d will need to be backup before logging off or shutting the computer

The only place you can put the launch of a Logoff or Shutdown script is in Group Policy. Click on Start/Run, then type GPEDIT.MSC and hit Enter.
Expand the Computer Configuration item on the left, then Windows Settings. This Scripts item is where the system's Startup and Shutdown scripts run from.
Expanding the User Configuration items, then Windows Settings, is where the User's Logon and Logoff scripts are run from.
You have to launch your code to do the backup from one of these places, depending on your requirements. But, a warning. The scripts only have a limited time to run. By default, it's 10 minutes. If your app doesn't finish it's work in that time, it'll be terminated and an error event logged.

I am confused about the data binding in the vb.net 2005.
I don't know how to use the below properties to bind with the database data and after adding and editing the data save back to the database.
[code]
Public ReadOnly Property CustomerID() As String Implements ICustomer.CustomerID
Get
Return mstrCustomerID
End Get
End Property
Public Property CompanyName() As String Implements ICustomer.CompanyName
Get
Return mstrCompanyName
End Get
Set(ByVal Value As String)
mstrCompanyName = Value
End Set
End Property
[/code]
Is there is any link where I can understand the complete usage of classes and data binding.
Thanks In advance

You would need to supply the code to read/write the data back to the database. If I understand your implementation (you're leaving out a lot of information!), you would possibly have a Customers collection class that holds these Customer (???) objects. This Customers class would be responsible for iterating over the items in its collection and updating the database with any changes, as well as retrieving customer records from the database and creating new Customer object from it.
This has nothing to do with data binding, which means that controls are bound to a data collection, like a DataTable or some other collection.
Or did I miss the point of the question??

Did someone say blatant plug?
Diamond Binding[^] will perform that task for you, and also keep those property definitions synchronised with your database with a handy VS addin.
If you want to do it yourself, which is extremely boring, repetative, and likely to break every time you change the database, then there is a quite a few articles on Data Access Layers (DAL) on codeproject. Everyone seems to love doing it the hard way :P

I am using vb.net 2005 as front end and Oracle 8.0.5 for back end.How I can add oledbdataadapter and configure this to Oracle database.Whenever I tried to configure the oledataadapter and try to select the connection it shows only two data sources in the list
1. Microsoft Access Database File
2. Microsoft SQL Server Database File.
Any Idea how I can configure this to Oracle Database?
Thanks in Advance.

You shouldn't need to select anything, just enter the connection string in code.
