Using a database in Visual Studio

Question

Hello all, I have a fairly simple problem I'm trying to solve. I would like to note that I am very much an amateur at vb, and while I know
what I would like to do, I'm not so sure on how.
Basically, I would like to fill several labels on my form from an MS Access database (which I've already linked), at the moment I move my mouse on to one of a number of other labels.
I was thinking that I would assign a value (Integer) to a function each time the mouse moves over a label. This function would then find the entry in my Access database primary key that corresponded to that value, and fill the labels with the proper data
from that entry.
I am fairly certain that this can be done, I am just not completely sure of the actual code. My function is a simple if/then. If the function = 0 then the labels are empty. else... you get the idea. What I don't know is how to link the value of the function
to the primary key in my database.
Any help would be appreciated!

To 'fill' a label you update its text property with a string - in your case, a string retrieved from a database record.  You probably need some rule for selecting
which database record you should use for the strings for the label text.
But you talk about mouse moves and functions and integers, and it is not clear how this relates to selecting some data from the database for displaying in the labels.   You need to provide more detail for this part of your task.
If you mean that the first time the mouse moves over a label then you should use record 1 in the database, the second time it moves over a label you should use record 2 and so on,  then you would do that with a form-level variable to record the counting,
and update that variable, and the label text, in the MouseEnter event for the label. See:

However it is not clear what the label being empty and your If statement has to do with this process. Instead of describing how you think you would do it, describe what you want to actually happen.
