Hi there,

I got a problem using an MS Access database through ASP.NET.

After updating my system from .NET Framework 1.0 to 1.1, my existing
application gives me the following error when opening a connection
with the code below:

"Unspecified error" (ErrorCode: -2147467259)

string connectionStringKey = "LocalDBConnectionString";
string connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data
Source=C:\InetPub\wwwroot\IS_Italy_2003\IS.mdb";

OdbcConnection connection = new OdbcConnection(connectionString);
try
{
connection.Open();
}
catch (OdbcException ex)
{
string error = ex.Message;
}
finally
{
connection.Close();
}

What's really strange is that:
1. The same application works on some of my colleagues' computers with
the .net Framework 1.1
2. The very same code works on my computer when creating a brand new
application with VS.NET 2003
3. The same application was working with .NET Framework 1.0

The same thing happens (including the two cases above) when using ODBC
classes instead of OleDB ones. In this case the connection string is:

"FIL=MS Access;DSN=AIS_Local"

and the error is:

"ERROR [HY000] [Microsoft][ODBC Microsoft Access Driver] Disk or
network error.\r\nERROR [IM006] [Microsoft][ODBC Driver Manager]
Driver's SQLSetConnectAttr failed\r\nERROR [HY000] [Microsoft][ODBC
Microsoft Access Driver] Disk or network error."

Need HELP!!!
tks

when I do following

 Console.WriteLine("hello\hello");
I see just hellohello
but I do Like this
 Console.WriteLine("hello\\hello");
I see what I was going to , there is another way to do the
same but I never use it(and could be wrong)
Console.WriteLine(@"hello\hello")

P.S. Check Your Connection_String

I believe your connection string is not correct, the one you have is the OLE connection NOT ODBC, try this,
string connectionstring=@"Driver={Microsoft Access Driver (*.mdb)};DBQ=C:\InetPub\wwwroot\IS_Italy_2003\IS.m db";
If you have the ODBC.Net online help avail type on index for "connectionstring"

Good luck
