I've been having a problem adding a record to an Access database using datasets and da.update etc. I'm trying to create a simple program that displays the records of a database table in a series of text boxes. I've managed to get my next and previous buttons working correctly and my update button works correctly too. The problem occurs when I try to add a new record. I keep getting a "Syntax error in INSERT INTO statement" whenever I click my add button.

is there a way to update a database row with the update command by first defining all parameters and then all values just like you can in the insert command? "insert into table1 (parameter1,parameter2,....) values (value1, value2,....)"something like "set table1 (parameter1, parameter2) values (value1,value 2,...) where ...."?because I only know the syntax to define each parameters value "set table parameter1=value, parameter2=value2... where"

View 1 RepliesIll start this by saying im still very new to VB, ive had some programming expereice here and there since high school, but never really did much with it till now.Ive got a small app that im working on for a side project, i want to add the details of a given days records from a simple POS system i have built up so far. At this point i have all of the information generated and i cant seem to get the app to commit it to the database. I have seen tons of posts on this, and i have followed a bunch of them to no avail. Im sure this problem is because i have the code written wrong, and i cant get it figured out. Here is the code that im using to try to save the data:

hours As Double = Math.Round(hoursworked.Hours + (hoursworked.Minutes / 60), 2)

I'm currently working on my A2 computing project, and I am having slight difficulties updating and saving the data in my database when it is entered on a form in VB. I cannot find any reason why it wouldn't work, but if someone could suggest a better way to do it, it would be great as everything else works. It's in the btnsave at the bottom, and when you click the button on the form it come up with a very unuseful error, which is no help to anyone.

I have experimented with other classes but I cannot get the database to update.
I am writing a program to assist Paramedic students in learning the Drugs that they have to know in order to pass their classes. I have created an Access database to hold all the information on these drugs, but not every student that will use this program will need to learn all the drugs contained within this database.
Right now I have 43 drugs in the database and still growing.
What I want to do is to present to the student the drugs and have them say "Y" or "N" as to whether its on their required list to learn. That way they only work on the ones that they need to.
