I have a little problem regarding the use of DBNull, NULL etc. in VB.net in combination with SQL Server 2k.
More specifically, I want to do something along the lines of this:If x = 0 Then
x = DBNull.Value where x is declared by Dim x as Object. I would rather use Double, but I can't assign DBNull.Value to this, and using Object works quite well, too. But every time I hit this condition, I get an exception: A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll This is not a major show-stopper, since the database value I write x to in the next step, is NULL by default - most of the time! So I need the ability to write NULL to it. If that was not the case, I would have been able to work around this by catching exceptions, I think - but sadly, this isn't really of use then.
Well I'm using VS2010 and I'm still fairly new at it, and with the databases in it. So here's what I'm trying to accomplish, and it too is also very basic I'm sure, but I haven't been able to figure out the few lines I need to accomplish it.
I have a generically database (Database1) and the generically names dataset (Database1DataSet) along with a table names Ruler_Information (tableadapter and bindings for this table). I have two text boxes named Ruler_NameTextbox and Ruler_PasswordTextBox. I want the database to accept these two textboxes as inputs for a new row. Here is my code, it obviously doesn't accomplish what I want, that's why I'm here:

View 2 RepliesI am currently developing an application that is linked to a MS SQL Server 2008 Database. So now I realised that I needed to make a few minor changes to the database (add new columns to some tables, change the data type of a few columsn in some tables). After making the changes, I realised that these changes have not been updated in my VB application's dataset. I then tried to "refresh" the dataset, but it still is not updating the dataset. What do I need to do to update the dataset to reflect the changes in the database?
View 1 RepliesI'm developing an application where depending on a textfile input i should update/insert some data into an Access database. Let;s say I'm updating the bookshelf of a book according to a textfile that goes like:
TEXTBOOK | BOOKSHELF
000000001 | 000000000A
and so on
[Code]....
does that make any sense? What I'm trying to do is basicalle: check if a book exists, if yes, then attach to Dataset, change its Bookshelf to the one in the textfile and repeat until the file is completely read. The Bookshelf can or not exists, if it doesn't then it should be inserted, is it done automatically when I update the Dataset? Finally "Batch update" the whole Dataset.
vs 2010, vb.net My program uses clickonce to automatically check my website for an updated publish, and then download and install if a newer version exists. I have been publishing my updates with the database excluded because if I include it, it overwrites the user's existing database with a new empty database.
My issue is that the new version of my software needs to have additional columns added to the existing database so that the user can save additional information. For example, the previous database table allowed saving client first name and last name, but the new version needs to have a new column for "address".
Is there a way for me to add a permanent database table or add a column to the user's existing database table without overwriting their current data?
using visual studio 2010. I have a vb.net application that needs to be updated periodically. The software stores client lists in a database for the user, but when the user reinstalls the program after I send them an updated publish, the client list database is replaced with a fresh empty database.
Is there a way that the user can reinstall the software without losing their current database?
I don't know if I need to somehow make separate publishes. One for an initial install to set up the database, and then one for updates that leaves the client database untouched? I don't know how to go about it.

I'm using a MS Access 2007 database. I modified the field definition of one of the fields in a table, it a text field and I change the maximum length from 40 to 150. I have a data source in my app that contains this table and many others. I refreshed the data source but the change didn't take affect. I went through configure option but the change still didn't take affect. It gives me this error,
The value violates the MaxLength limit of this column.
If I add/delete a database field the data source is updated when I go through the configure process. I finally just deleted the table from my data source and then added it back.
