Hi i am trying to create a simple vb application that connects to a Microsoft access database that stores basic information of student name, id number and result. my code is working to an extent but when i run the program and add new records the new data i entered saves no problem and i can see while the program is running but when i stop de bugging and start de bugging again the new information i added to the database the last time doesn't appear. only the information that i inputted originally into the database through the access file show up. any info or help would be appreciated.
