VS 2010 Update Database Without Overwriting On Publish?
May 17, 2012
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?

The following code writes some data on an xml file. If I want to write on the same file twice the code overwrites the old data with new ones. How do I update the data instead of overwriting them? (i.e., write at the end of the xml file instead of overwriting the data)
Dim XMLobj As Xml.XmlTextWriter
Dim enc As New System.[Text].UnicodeEncoding()
XMLobj = New Xml.XmlTextWriter("C:" & current_scen & ".xml", enc)[code].....

I have a database called NurseLocationI have a table called CoverList with two fields UserId and CoveringI can connect to the database fine and read the fields into variables that I can use in my program. w I want to take an existing variable called userFullName and put it into the Covering field where the UserId is = to "LHV"This is my code on button click to do that.But I was told I shouldn't use INSERT because it creates a new field

I made a program which uses sample.dll. The program communicates with this .dll and does various tasks. Now, lets say I developed a new dll (an update, pretty much). Can I just give my users a new copy of the .dll or do I have to re-reference it in my project and then compile my programs all over and then give them a new copy of the entire program?

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:

I 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?

I'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.

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.

ive created a program in VB 2008 and i cant remember how to publish it in such a way that it includes the database that the program uses. At the moment when i publish it, it only works on my system because i have the database on my PC, if i delete the database from my pc the program messes up because it doesnt have a copy of the database in its program resources etc.how do i publish the program so that it includes a copy of the database that it needs to function?

I'm having some trouble sharing my application to other PC users. I have tried to Build my application and Publish my application into a folder, zip it, and put it on my website for people to download, but when they try to run the setup file it gives an error message saying they need to download "Mysql.Data V 6.4.4.0", which makes sense seeing how I have a resource that uses this. Do I need to use a different method to pack my application or what? I don't quite understand how I can incorporate this into the files so the end-user doesn't need to do any other downloading than my file.
