OleDbCommand selectCommand;
OleDbDataAdapter oda;
DataSet ds = new DataSet();
selectCommand = new OleDbCommand();

connectionString = ''Provider=Microsoft.JET.OLEDB.4.0;'';
string Str_ColNames = objImportDB.get_importcol_sequence(Int_FeedId, '''');
Str_SelectText = ''SELECT '' + Str_ColNames + '' FROM [Sheet1$]'';
connectionString = connectionString + ''Data Source='' + fld_path + '';'';
ExtendedProperties = @''Extended Properties=''''Excel 8.0;IMEX=1;HDR=YES;'''''';

SOURCE: Write Error

That's almost an adequate error description! It is odd that a 24x CD speed description is given for burning in a DVD-RAM; what media and session types did you pick? If there is nothing (hair, fingerprints, soap...) on the particular disk preventing a burn, perhaps something has a write lock on dlgbrnst.cpp so it can't be reeled off to DVD-RW?

SOURCE: vb 6.0 ado connection without ado control moving next record

I see 2 problems with your code.

1) Each time you call cmdnext_Click, you're reopening the database. Each time you do that, you start at the beginning of the file. You need to have the database opened once, somewhere else in your program. Be sure that the record set is visible from this sub.

2) In order to use the "Next" function, you need a loop like this

'test for no records
IF REC.BOF and REC.EOF then
msgbox "No Records Found"
exit sub
end if

IF NOT REC.EOF then
REC.MoveNext
(display your fields)
END IF


Again, this will only work if your database is opened outside of the cmdNext_Click routine.

I can't help you get this current problem solved.

However I can help you prevent it in the future.
Get a whopping BIG outside hard-drive for your backups.
Then you have ALL your back-up files on one continuous disk, instead of several.

You need a program that automatically backs-up only the files you have pre-selected, as an actual file and not an "Image".
Back-up such as Desktop, My Documents, Email, Favorites etc.
With "image" files you can not retrieve or copy and paste individual files from the archives, such as when you have accidentally deleted a good file on the computer.

My AR DSI says My game is corrupt


Have fixed this on the DSi by deleting the Mario Kart DS file using the Action Replay DSi Code Manager software. Under MY CODELISTS on right hand pane create a new file by clicking NEW then right click ADD NEW GAME type in both game code and game ID e.g. ACMP E45A2937 for Mario Kart DS. Right click Mario Kart DS and select add new cheat. The cheat codes can be copy and pasted in here.
Drag and drop the file from the right hand side to the left hand side of the window so that it appears in the memory card list. Press COMMIT CHANGES to save.

Developing an application with vb.net 2008 and i'm finding it


You need to set up an ODBC DSN and use this in your connection string then instantiate an ODBC connection. For example:

Dim MyConnectionString As String = "Driver={MySQLDSN};SERVER=localhost;DATABASE=MySQLDatabase;" '
Dim conn As New OdbcConnection(connectionString)
conn.Open()
Dim da As New OdbcDataAdapter("SELECT * FROM Customers", conn)
Dim ds As New DataSet()
da.Fill(ds, "Customers")
dataGrid1.DataSource = ds.DefaultViewManager
conn.Close()

How can i save the data inputted from a textbox to the recordset or to its table in MS Access?


If you want to save it in MS Access, you need an OLEDB Connection.

You need to declare few arguments first to accomplish your tast like, OLEDB Connection String, Connection, Data Adapter....

I'll write a simple program to show you.
---------------------------------------------------------------------------
Const cn As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "data source=path of Access file(2003) where you want to save input data.mdb;"

Dim conn As New oledb.OleDbConnection(cn)

Dim objda As New oledb.OleDbDataAdapter

Dim cmd as string = "insert into login (loginid,pass) values('" & TextBox1.Text & "')"

conn.Open()

objda.InsertCommand = New OleDbCommand(sql, conn)

objda.SelectCommand.ExecuteNonQuery()

conn.Close()
----------------------------------------------------------------------

Copy and paste the above source code, and then tell me what happens.
If you got any more quries, don't hesitate to ask.

And If I was helpful, Kindly do Rate!
Regards,
Waqar.

Code for find the Ms access database size using visual basic


The way to get the database size is to point to the directory that the database is do a DIR statement with an output to a file as in DIR payroll.mdb>dbsize.txt and then read from the text file, the first field of the second line being the name (which you really don't need) then the size value of the database.

To import the text files using VB 8 use

'Imports System.Data.OleDb Dim conn As New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=d:\path\filename.mdb") Dim cmd As New OleDbCommand("SELECT * INTO [import] FROM [Text;Database=d:\path;Hdr=No].[dbsize.txt]", conn) conn.Open() cmd.ExecuteNonQuery() conn.Close()
