View 4 RepliesDB/Reporting :: Creating A SQL Server DB Through VB Code
Jul 1, 2008I'm trying to write code to create a new database and then create tables within the database.
I'm running into a strange problem right now, which is the fact that I was able to create a new database ok on either the regular SQL Server instance, or the SQLEXPRESS instance. However, when I attempted to create a table, I got an error message saying that there is already a table of the same name.
When I tried to connect to the new database via SQL Server Management Studio, I could see the database. However, there are no tables in it! So, theoretically, I'm creating a brand new blank DB, so there should not be anything in this DB, right? and I should be able to create any tables I want in it!
Here is the code that I have so far:

I just have one simple form with a button on it. The click event on this button calls the CreateAllDBs() routine.
VS 2008 Creating 'custom Code'
Aug 6, 2010I have a form that is populated with specific data for each user. The user chooses this data themselves.I plan on saving this data in the application settings or via xml serialization.What I want to do, is allow users to generate a unique code for that data so that they can supply this code to others and all they will have to do is copy and paste it into their client and that data will populate for them.I could just allow users to trade XML files, but I want it to be easier than that.The form is basically setup this way;
Picture - Data 1, Data 2, Data 3, Data 4
Picture - Data 1, Data 2, Data 3, Data 4
The pictures correlate to pictures that are numbered anywhere from 0-600. The data can be any integer value from 0 - 200.
