Hello vb.net forum users, I'm an A level Computing student working on the A2 Coursework Project, where we have to make a software for a company. I chose to make a sales invoice system for a small computer hardware store, it had to involve an access database so that's what the backend for this is. We were however meant to be finished with the actual software about a month ago but I'm not very good at programming at all...so I left it until now!

 

I've been working my hardest at it but nothing seems to work, I'm encountering numerous problems :

 

coming up with a way of to subtract sold quantity of items from the current stock level when a sale is made

 

saving changes and updatesmade in a datagridview to the database

 

there's a listbox which is databound and wont update to reflect the actual database's contents just what was in there when it was bound.

 

making a the tables searchable through keywords in a form (totally clueless on this one)

 

 

I've been googling all over for solutions and tried numerous things but I can't seem to tackle any of these problems, could someone here please help me? I would greatly appreciate it

 

For anyone who decides to examine my program...I apologize in advance for the lazyness in keeping the code tidy and etc, and my name choice of controls, it all caught up with me and confuses even me now..
