&"user id=joeuser;pwd=pass;pooling=false"
Dim gsConnection As New GBaseConnection( gsConnString )
gsConnection.Open()
MessageBox.Show( "Server Version: " +
gsConnection.ServerVersion _

gsConnection.Database )
gsConnection.ChangeDatabase( "test2" )
MessageBox.Show( "ServerVersion: " +

[C#]
public void CreateGBaseConnection()
{
string gsConnString = "Persist Security

GBaseConnection gsConnection = new
GBaseConnection( gsConnString );
gsConnection.Open();
MessageBox.Show( "Server Version: " +
gsConnection.ServerVersion + "\nDatabase: " + gsConnection.Database );
