Hi,

I have an application which uses SQLite as the backend db. The db is encrypted with a password I enter each time I want to open a connection. Below is the code I use top open a ODBC connection to the DB:
Code:

SQLiteConnection cnn = new SQLiteConnection("Data Source=c:\\test.db3")
cnn.SetPassword("myPass")
cnn.Open()


This works fine. However, when I try to connect using VDO objects using this code:

db.open("DRIVER=SQLite3 ODBC Driver;Database=c:\\test.db3;option=3;Password=myPass;)

I get the following error:
Quote:

file is encrypted or is not a database (26)

" at ADODB.RecordsetClass.Open(Object Source, Object ActiveConnection, CursorTypeEnum CursorType, LockTypeEnum LockType, Int32 Options)
at Infralution.VirtualData.VirtualConnection.GetRecordset(String query)"


Note that I have no problems using the connection string above when the DB is not password protected.

I'm not sure what method you are calling - since VirtualConnection does not have an "open" method. If you are passing that connection string to the VirtualConnection class constructor then you might want to try removing the password part from the connection string and passing the password to the separate password parameter ie:

Code:
VirtualConnection vc = new VirtualConnection(
    "DRIVER=SQLite3 ODBC Driver;Database=c:\\test.db3;option=3;",
    null,           // user id
    "myPass",  // password
    -1,             //options
    10);           // record cache set size


If you are still having problems try creating the ADO connection and opening a recordset directly eg

Code:
con = new ADODB.ConnectionClass();
con.CursorLocation = ADODB.CursorLocationEnum.adUseServer;
con.Open"DRIVER=SQLite3 ODBC Driver;Database=c:\\test.db3;option=3;",  null, "myPass", -1);
ADODB.Recordset rs = new ADODB.RecordsetClass();
rs.Open("SELECT * FROM MyTable", con, CursorTypeEnum.adOpenStatic, LockTypeEnum.adLockOptimistic, -1);


If you can't get ADO to open the recordset with your connection string then you won't get VDO to work.
