I have created a form using c#. I wish to have a direct connection with an access db that I have created i.e. If I enter assetID , the app should retrieve all data associated with rows corresponding to that ID and automatically update in the db the date when the button is clicked . Would someone be able to provide me a small code for the same?

CP helps people to learn. We neither do their assignments/homeworks/projects nor supply source code.

If you encounter any difficulties with your coding, always consult Google first, everything else fails, then visit CP and ask questions related to specific issues.
Nevertheless, since you are here, you may want to learn and adapt from the following links:

Not here we won't, no.

We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Try it yourself, you may find it is not as difficult as you think!
