Dear All I purchased a Lenovo T61 laptop with DOS only. I purchased Win XP Pro (OEM) version with it and already installed it on the machine. Now, I want to go for Vista Business. Can I purchase an OEM version of Vista and install it into the machine which has already an OEM XP Pro? Or I should purchase Normal Vista (Wich is more expensive)? Is that legal? Thanks Mohammed

I know that the hardware of the Mac is completely different from IBM alike systems. Vista is primerly designed to work with IBM alike system. So, If we installed it in a MAC system. Will it deal with all the hardware of the system? Will I use it as it was installed in an IBM system? The main point is that will I face any conflicts in the system???? thanks Mohammed

Dear all I created a Data Entry web page (PHP) that has a form with a number of components such as name, mobile , age, etc... (text fields). These data is entered in the database. This page is used by more than one user at a time. The problem is that some records are entered twice or more in the database. There are some records was entered 15 times and all of them at the same time. I am sure that my code execute the SQL statment once only. What could be the problem? Why the script is executed more than one time? Is it a Thread issue? Is it a Server issue? My database is Oracle and the page is in PHP. regards
