2010 Access And Change Information In A Database With Only Code?
Jun 15, 2010First, I would like to add a text box search field to this form (because navigating through several thousand users with arrows isn't going to work). When the search button is pressed, I want the username to be looked for. If found, the form (and each textbox, option button, etc.) is updated with that user. I can then modify the user's information and press save.
Second, how do I access and change information in a database with only code? For example, if I periodically want to check every user in the database to see if they have over "100 points" and if they do, I subtract 10 points from that user.

VS 2010 Add Column To Datatable And Save To Database
May 1, 2012I have an application that users will save a list of clients to a database. The extension on the database is .sdk, and I think is some kind of sql database. The user can save rows and add rows to maintain a client list, but when I release an update, I have to install it without the database file. If I install with the database file, then their current client database is replaced with a new blank database.
my issue is that I need to add columns to tables in their existing database without overwriting their current rows. For example, i have columns for client name, address, and phone number currently. On my next update, I want the user to be able to save client birthdays. Here is what I have:
