c# - “error isam instalable cant be found” -

-

i'm trying connect windows form app embedded database (.dbf) , keep getting message no matter connection string:

error isam instalable cant found

here code i'm using test whole thing:

private void bguardar_click(object sender, eventargs e) {     try     {     string cadena = "provider = microsoft.jet.oledb.4.0; data source =d:\\; extended properties = dbase iv; userid =; password =;";     oledbconnection con = new oledbconnection();     con.connectionstring = cadena;     con.open();     messagebox.show("conected");     con.close();     }     catch (oledbexception exp)     {     messagebox.show("error: " + exp.message);      } }
