How to make connection to a database using an existing odbc connection in 64 bit platform

Hi,

Below is the code I tried to achieve the above.

private void MainForm_Load(object sender, EventArgs e)
{
string connetionString = null;
OdbcConnection cnn;
connetionString = "Data Provider=SQLOLEDB;Dsn=dsnname;Database=dbname;Uid=admin;Pwd=pwd";
cnn = new OdbcConnection(connetionString);
try
{
cnn.Open();
MessageBox.Show("Connection Open ! ");
cnn.Close();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}



But getting an error message as shown below:

The Specified DSN contains an architecture mismatch between the driver and application.

I am working in a 64 bit PC.

Please shed some light on this...
