When Inserting Data Into A Database Get A Conversion Error
Sep 2, 2010
I'm working on a form that allows to add new users to a users table in my Access database. The table only has 3 fields: user (string), password (string) and admin (boolean). user is the primary key. But when I run it and try to add, I get an error when casting the query to Double (?). I don't have any double variables or table fields, and I'm not trying to cast anything from or to double. So I have no clue about how to fix this. The code I'm using to insert (and it's working correctly on other forms and tables I have) is:

I am trying to insert data into my database but because i have relationships in the database, i can't enter data into one unless the other has been entered but i can't also do all that at the same time.This is the error i get: You cannot change values of this column because it is related to another table, what do i do and what is the next best option if i don't want to use "autonumber" but want to make sure i don't repeat numbers. How do i implement that?

I'm trying to do that with the following code:

I have a deployed desktop application which uses an Access Database. I have a need to update the databases which are in the field by adding a few extra fields to some tables to support new functionality. Thedatabases is password protected.
The process I am following is to ship a new empty database which contains the new fields (these fields are set to not require entry, accept nulls and they are not indexed) and then add functionality to the application which selects the data from each table in the current deployed DB and inserts it into the same table new template database. Then I kill the original db, rename the new template to be the file used by the application.
I am using OLEDB to communicate with the database and have tried using an 'INSERT INTO' but cannot get the syntax right - I used this example[URL]..but it throws and invalid argument when I try to supply a database password
