within the SqlCeCommand framework of VB.net, I am looking for a simple coding example to return data from the last record of an SQL database. The purpose is to return the last sequential "counter" value from the primary key of the database, and then append additional records to the database, continuing the counter value from the last record. This counter value will of course vary with each update.

I have a problem with my program, and it's really bad because I need to burn it to disk within 12 hours and I can't get it to work: If I create a record, add information to it and click on Next Record, the ID, Status and Notes boxes content will change but the rest of the controls contents are carried over to the next record and I don't know why or how. It was working perfectly but now it stopped and I never done anything.

View 2 RepliesI have a access database with these columns. USER_ID,COUNT,TIMES
Let say the current record is this:

Now I want to updated the current count record and times, but before updating I want the old record to be added to the new record. What should be my query?
I have a MS Access database set up, with a Period field that has either values 1, 2, 3, 4 or 5. I retrieve these values using a database connection and I would like to reference a particular control based on what period was grabbed from the database.
Here's example code, pseudo of course.
TextBox(dr(3)).Text = dr(0)
dr(3) contains the period, and dr(0) contains the content I would like to put into the text box. I have these text boxes on my form: TextBox1, TextBox2, TextBox3, TextBox4 and TextBox5.
So if dr(3) contained 2 then I would want to reference TextBox2.
how to view the next record and previous record in the database.? just like in the picture below.? what condition should we use.?
