View 22 RepliesI 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.

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.

I am INSERTING into 2 different tables with 2 different buttons (One after the other by clicking each button). I have a form with 1 button directly on it to INSERT into tblCustomers from a field that is directly on the form as well. I then have a TabControl with another button with other fields (5 to be exact).
After I add data to the data base by filling out the field on the form and then by first clicking the add button located directly on the form and then add data to the fields directly on the TabControl the data will not INSERT itself into the tables in the data base for the 2nd table. Only the first table get data in it and not the one related to the TabControl.
BUT if i add data in the TabControl and then click the button on the TabControl it adds data into to the 2nd table. Is there a way to refresh my program so that it will accept both the "forms data" and the "TabControl data"?
I have problem when i inserted data. the error show String or binary data would be truncated. What is meaning of that??

My problem is when I try adding a new appointment I get an error that says ""Column 'AppID' does not allow nulls."" Editing existing appointments is fine and it updates the DB no problem. I don't have an INSERT statement right now (which might be the issue) so I was thinking of doing this: INSERT INTO [tablename] ( [column1], [column2], ... ) VALUES ( [value1], [value2], ...) Only problem with that is I would need to use the textbox names for the VALUES, and that form that pops up to gather appointment info is from a third party, and I can't find the names of any text boxes
View 2 RepliesI've written the following code to add a new record to a database:
Public Shared Sub AddTopicUser(ByVal UserID As Integer, ByVal TopicCode As String)
Dim RowsAffected As Integer
Dim ATUDCONN As New OleDbConnection
ATUDCONN.ConnectionString = DBCONNSTR
Dim ATUDCMD As New OleDbCommand("INSERT INTO tblSubscriptions (UserID, TopicCode, Completed) Values (@UserID, @TopicCode, @Completed)", ATUDCONN)

I recieve no errors from the code, but when i open the database after - the record has not been added.
I have checked that the values being passed as parameters to the function are valid. I was curious as to whether I was formatting the OleDbCmd correctly, which is why i added a message box function to show be the value of the connection string which at runtime is: when they're not being added to the db?
