VB.NET Programmers

Are there any VB.Net Programmers on this board?

I just started using 2005. But as of now I don't know crap. ;p Any plans to release the source?

Something a little bit more advanced than that. Wanna join an open source team?

Just to bring this old thread to current - I just installed the free version of vb.net 08 and am trying it out now. I will do some benchmarks and see how much better it is for what I do. Right now I'mm trying to figure out how you do mysql programing and how do you access the DB? (with a dll?)

Just tried the 08 version and the syntax to write and read text files is entirely different, and very hard. Is this something that's different in 08 over the 05 version? Can't believe it's that different. Might as well start learning VC++

George, congratulations on picking up .Net!

Coming from VB you'll have a bit of a learning curve, but once you're past that you'll be good. MSFT has plenty of stuff out there to get you up to speed coming from VB.

As a side note, if you really don't want to leave VB6, isn't MSFT continuing support for the foreseeable future?

Good luck either way!

Writing to a simple text file is as easy as:

Code:

Dim oWriter As StreamWriter 



oWriter = File.AppendText(Filename)

oWriter.WriteLine(Message)



oWriter.Close()

You will need to add:

Code:

Imports System.IO

to you the top of your file if it is not already there as well.

As for accessing MySql you will need to download the MySql.Net connector from http://www.mysql.com

This connector functions exactly like any ADO.Net connector so any tutorial on ADO.Net will give you how it works, you just need to change the varaible types to the appropriate MySql connector types such as:

MySqlDataReader
MySqlDataAdapter

as opposed to:

SqlDataReader
SqlDataAdapter

DataTables and DataSets are all the same whether you use MySql or any other DB.

I am using the 05 version since there are still non-depreciated commands. Over the next few weeks I'll dip deeper in the syntax, although in all honesty, I'm leaning towards C++

Does anyone have the mysql connection syntax (i.e an example)?

Actually, I think c#.net would be a better choice for database apps, I have had great success with it in the past and it is far far easier to work with as well.

I would recommend C# as well.

As for an example of how to use the MySql.Net Connector:

I have one posted here using C#, if you would like something in VB.net I can convert it over; however, since they are both .Net the object structure and design is all the same only the syntax changes.

Hey GeorgeS,

Once you have MySQL Connector.Net 5.1.6 installed,
add a reference to it (MySQL.Data)

Code:

Imports MySql.Data.MySqlClient

Public Class MyClass



    Private mydb As New MySqlConnection()

    Private con_str As String = ""

    Private reader As MySqlDataReader



    Public Sub New()

        con_str = "server=SERVER_IP;Port=3306;user id=root;password=PASSWORD_HERE;database=DATABASE_NAME;persist security info=True"

        mydb.ConnectionString = con_str



        mydb.Open()



        Dim sql_cmd as String = "SELECT * FROM variables"

        Dim cmd As New MySqlCommand(sql_cmd, mydb)



        reader = cmd.ExecuteReader

        While reader.Read

            For i As Integer = 0 To reader.FieldCount - 1

                debug.WriteLine(reader.Item(i).ToString)

            Next

        End While

        reader.Close()

        reader = Nothing

        mydb.Close()

        mydb.Dispose()



    End Sub

End Class

I have a transactional database interface class that i wrote, that if you're comfortable with array lists, then it'll probably be a big help.

I'm really happy that theres posting going on in my little corner of the Forum, but since it's in regard to GeargeS's tools; could all posts for GeargeS please be placed in GeargeS's section. I'm sure that would make his day.

Also, C#, J#, and VB.net are all the same engine. Anything done in one can be done in the others so long as there is a library for that particular syntax. Other wise the programmer would need to make a wrapper class which is a pain and why I only have three 3D engines available.

As for C++, enjoy Windows API and long compile times. I use VB.net because it's easy for me to read (Though I wish I could use C#/C++ comment methods, /* */ is cool for block comment.) and all the .net compile at a sickinly fast pace.

All times are GMT -4. The time now is 12:59 PM.
