I have an Address Book project with a listbox. The listbox is bound to the database via the little arrow pop-up box in the corner of the listbox.

View 4 RepliesI have a data set with a parent child relationship between a patient table and an insurance table. There can be up to 4 insurances for each patient. I want to display them in 4 separate panels of a vb.net form. So if a patient had 2 insurances, then txtName1.text on panel 1 would have the company name of the first insurance, txtName2.text on panel 2 would hold the company name of the second insurance, and so on.
How do I display only the insurances related to the current patient? I've tried moving through the rows of the related table, but that gives me all the rows, not the ones I need. Everything I see on the internet suggest using a datagrid, but that's not an option in this case.

View 8 RepliesThis question is a follow up to an earlier question I had that was quickly resolved. The previous question can be found here: Selecting TOP 4 records from multiple SQL Server tables. Using vb.net..I selected the top 4 rows from multiple SQL tables ordered by date. How would I then go about placing that data into labels. There should be 16 items in total (4 columns, 4 rows). However if I try to use sqldatareader I only get items 0-3 and anything more is outside of the array. Should I not be using an IF statement in this case?
