Re: Problem with Access Dave Kreskowiak27-Dec-04 4:45 Dave Kreskowiak 27-Dec-04 4:45  What is the EXACT exception message? Without it, there's nothing we can do to help you. My first GUESS would be that there was a problem with a duplicate primary key, but of course, I'm only guessing... RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome Re: Problem with Access Briga28-Dec-04 23:45 Briga 28-Dec-04 23:45  Well things are weird. I also added an XML just for text. So I load the DB with .readxml and before using the Update methos I also save it to an XML file with WriteXML. In the beginning I got problem with XML in reading (not in saving) due to invalid values. I changed every field as nillable and now it works (XML). The Update method doesn't generate any exception anymore but the .mdb is empty. The new code is: DB.AcceptChanges() DB.WriteXml("c:\RF.XML") ' *** salvataggio XML conn.ConnectionString = String.Concat("Provider=Microsoft.Jet.OLEDB.4.0;Data source=", cfgDBDirectory, "\rfgprii.mdb") Try conn.Open() SelectCMD = New OleDb.OleDbCommand("SELECT * FROM Coordinate", conn) SelectCMD.CommandTimeout = 30 DBAdapter.SelectCommand = SelectCMD CustomCB = New OleDb.OleDbCommandBuilder(DBAdapter) DBAdapter.Update(DB.Coordinate) Catch ex As Exception MessageBox.Show(String.Concat("Errore nell'accesso alla base dati archivio:", ex.ToString), "RFGPRII", MessageBoxButtons.OK, MessageBoxIcon.Error) End Try Now I also put a rem in front of the .writexml just to see if that instruction was affecting the Update. Still it generates no exception but the .mdb is empty. So to recap the exception was due to the nillable parameter (although there were no null values) and it's gone. The problem now is that the Update method does not work. The DB is empty. Any clues?

Other way is to prepare rtf string as par RTF specification, the specification is available on msdn.

Jay Shankar27-Dec-04 14:08 Jay Shankar 27-Dec-04 14:08  RTF Control, what is the namespace of this class? By the way, RTF Specification does not say anything regarding Tables. Please note that the rtf document should ideally be opened in WordPad, in which table is not supported. Reports Integrated with Setup in VB.Net???

If you know please help me. Re: be rollbacked my transaction Rob Graham26-Dec-04 10:47 Rob Graham 26-Dec-04 10:47  Might help if you told us what the error was, and maybe posted your code... Why would anyone waste time arguing with an accountant about anything? Their sole function is to record what happenned, and any higher aspirations are mere delusions of grandeur. On the ladder of productive contributions they are the little rubber pads at the bottom that keep the thing from sliding out from under you. - Roger Wright Re: be rollbacked my transaction Dave Kreskowiak27-Dec-04 0:48 Dave Kreskowiak 27-Dec-04 0:48  Like Rob said, it would help greatly if you posted your code. Also, it's better practice to create the table in one transaction, then create the indexes in the next. If the table creation fails, what's the sense in creating the indexes on it?

Just add a new C# Class Library project to your existing solution. This new project will be compiled to a DLL. Then reference the C# project in your VB.NET project (also remember to check the project dependencies). Of course you could also first compile the C# sources to a DLL and then reference the compiled DLL. But using a multi-project solution has the advantage of enabling you to quickly change the C# sources if necessary. For more details see Managing Solutions, Projects, and Files[^] (in particular Multi-Project Solutions[^]). Best regards Dennis
