VS 2010 Update Program But Maintain Database?
May 1, 2012
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.

Is there a way to maintain application modified Settings in the settings files after a program update? i.e. I have 10 or so values in the settings file and the users can modify them... when I send a program update they revert back to what I initially programmed them to be.

This program is very difficult for me, but I must get threw it or I cannot finish... What I am doing is making a Database of foreign Languages with the spelling of the words and the pronounciation inside the database... The USER enters a paragraph of words into the translator textbox and pushed translate. The program has a DATABANK of words with the phonetic spellings and matches the word, then translates to phonetics. The problem is that new words keep appearing inside the language. So I incorporated a Database of 2 fields

I am using Visaul Studio 2010 to build a Windows Forms application to maintain a table in an SQL Server 2008 database. The table is named CASHBOOK and here are the further details:
DATE | DESCRIPTION | DEBIT | CREDIT | BALANCE
--------|----------------|---------|-----------|---------
1/1/2011| CASH BALANCE | | | 5000
1/1/2011| SALES | 2500 | | 7500
2/1/2011| PURCHASE | | 3000 | 4500
2/1/2011| RENT | | 4000 | 500
2/1/2011| SALES | 5000 | | 5500
I can use CASHBOOKTABLEADAPTER.INSERT(...) to insert appropriately, but my problem is how do I update the BALANCE column?

I believe I have 2 problems. First, I have 1 program (VB6) that reads and stores emails from a department mailbox into a database. This program uses mapi and CDO. I have a 2nd program written in VB 2008 that displays the email information that was stored in the database. Everything works fine except the user now needs all formatting to be displayed ie highlighted, bolded text, etc contained in the email. The first problem is the email is stored in the database as plain text. I don't know how to get HTML formatted text from MAPI/CDO. Secondly, if I did store the email message in HTML format, would I be able to display in a .NET control on the form other than using the Web Browser?

Well need to make a separate update program and I need some way of getting my main application's version. I thought about making a text file with the version but I can't write to the program files folder with permission, thats why I have a second program. I also though about making the update program's version the same as the main application, but that doesn't seem right because I have to update the update program. So is there a way I can get the main applications version inside the update 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:

Is there any method to do batch update winForm in VB 2010
Using Microsoft Access2007 as database, VB 2010 WinForm (DataGridview + Textbox)
There are a lot of record need to be Updated, It is very efficient if that data is just going through Batch Update, meaning just one click will update all the data rather than click one by one.
Any Demo or code showing how to do this Batch Update (VB.net).

I've created a form with several controls to specify the inputs to my program. They include TextBox, OpenFileDialog, Button and even a user control for numeric input. When the user clicks the 'GO' button, the program begins it work. Opening several files and processing a bunch of numerical data. This could take many minutes/hours with large datasets.
What I've been trying to do is have another window/form open up and send status information to it for the user to view. The info to be displayed is varied and constantly updated as the program crunches the numbers. Many many programs do just this type of activity.
I attempted to create a second form with a huge TextBox thinking I'd just write stuff to it. I called the .show method within the .click of the 'GO' button and of course the form is displayed but control of the program's execution doesn't return until the form is closed. How to I maintain execution and have a second window/form to display status?

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?
