Hi,

Please see my code below..

string DSource = Path.Combine(CommonItems.DatabaseLocation, lb_project.SelectedItem.ToString() + ".mdb");
string Connection_String = "Provider=Microsoft.Jet.OLEDB.4.0;Jet OLEDB:Database Password=1234;" + "Data Source=" + DSource + ";";

ADOX._Catalog cat = new ADOX.Catalog();
cat.Create(Connection_String);

Catalog catalog = new Catalog();
Connection connection = new Connection();
connection.Open(Connection_String, null, null, 0);
catalog.ActiveConnection = connection;

Table seq_table = new Table();
seq_table.Name = "seq_data";
catalog.Tables.Append(seq_table);

seq_table.Columns.Append("seq", ADOX.DataTypeEnum.adVarWChar, 20);
seq_table.Columns.Append("rev", ADOX.DataTypeEnum.adVarWChar, 100);

connection.Close();

After creating the database I am closing the connection, even though the ldb file is still existing until I exit the application.
what is the wrong with my code?.I know ldb is not a dangerous one, but I need to avoid unnecessary connections. Please help me on this..

You are actually open the connection twice ,but closing once - the second one will be closed only after your application exits...
First:

C#

cat.Create(Connection_String);

Second:

C#

connection.Open(Connection_String, null, null, 0);

Looking at your code, the first can be removed and you still get the same...
