You may find the MySql Connector/Net[^] to be useful. Just replace your SqlClient references with the new references for MySql. And as Christian said in his reply to you, as long as you did not use any SQL Server-specific commands you will be good to go.

OK.. Pardon my ignorance please.. but what do you mean by replace SqlClient references with the new references for Mysql. Can you give me a example ?
Thanks in advance

Sure. This is probably how your code using SQL Server looks:
Imports System.Data.SqlClient
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim DatabaseConnection As New SqlConnection("connectionstringgoeshere")
DatabaseConnection.Open()
Dim SQLCommand As New SqlCommand("SELECT * FROM TABLE", DatabaseConnection)
SQLCommand.ExecuteNonQuery()
DatabaseConnection.Close()
End Sub
End Class
Now, after you have downloaded and installed the MySql Connector/Net, open the project's properties, click References, click Add, and add C:\Program Files\MySQL\MySQL Connector Net 5.1.6\Binaries\.NET 2.0\MySql.Data.dll. That's the default directory, it may be somewhere else on your computer. Next, change your code to MySql. I bolded the changes:
Imports MySql.Data.MySqlClient
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim DatabaseConnection As New MySqlConnection("connectionstringgoeshere")
DatabaseConnection.Open()
Dim SQLCommand As New MySqlCommand("SELECT * FROM TABLE", DatabaseConnection)
SQLCommand.ExecuteNonQuery()
DatabaseConnection.Close()
End Sub
End Class
Again referring back to what Christian said earlier, as long as you don't do any SQL Server-specific queries you should pretty much be able to just replace the SQL Server stuff with the MySql stuff. Make sure to update your connection string to be for MySql. (You can also use OleDbConnection if you don't want to use the MySql Connector.)
Hope this helps...

I am using tableadapters built from the data source so I can't just replace the sql server commands with the mysql commands. I guess I thought I should be able to just change the
connectionstring and provider name in my config file and it would go to the MySql database.

I see someone posted it. I recommend you read the article I link to in my sig, buy a book on VB.NET and learn some basics so you have a basis on which to understand answers given to you. If you can't work things out based on being told what method to call, you're probably just cutting and pasting code you're given but don't understand, and that's not how to learn.

Hi All, I recently developed a shared COM Addin using VB.Net and Outlook 2003. It works great on local machine but when I install it on Terminal server it doesn't work.
My Addin get installed on Windows 2003 Terminal server with the initial Loadbehavior = 2Hex value under the HKEY_LOCAL_MACHINE in registry. It starts working when I change it to 3Hex. But as soon as another user logs in on termail server and starts outlook, the loadbehavior values becomes 2Hex again and my Addin stops working for all users.
Any idea why registry is being changed by multiple user sessions. I will appreciate your response.
Thanks

Hey Mitresh, Many thanks for your response. My Addin is a Shared Addin not VSTO one, do you think these steps are same for shared addin?

Hi, I did follow the article but still same problem. I guess this article addresses VSTO Addins not Shared COM Addins. Just for the test purpose, I created a small shared COM addin for outlook 2003. After installation it worked fine but as soon 2 users started outlook session (on Terminal server), it stoped working and again Registry Loadbehavior value changed to 2 from 3. This thing is driving me crazy. Does anyone guide me where I am wrong?
Thanks

I guess I'll get a 1 vote for this, too, but, the other reply is correct. Do you have a problem, or do you just have no idea how to code this ? What have you tried ?
The list box has a selected index changed event, you can use this to populate the second list
