Hey guys, i am starting out with VB.NET and i just created a "Hello world" application but when i compile and run it it gives me the following results on the result screen, but the program itself compiles and runs perfectly fine

Well if your program runs fine and your computer seems to run fine then I don't think it's a serious problem. However, you may still want to contact tech support and see how you can prevent this.

after looking around on google for a while i came up with some information, those arent error messages they are simply the debugger information saying "No symbols loaded" sort of like an informative thing, it can be disabled if you manually edit the Project-properties information under the debugger section in VS2005 Very Happy

Here you go Very Happy
code:

Public Class Form1

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        PictureBox1.Visible = False    ' hide picture
        Label1.Text = CStr(Int(Rnd() * 10))    ' pick numbers
        Label2.Text = CStr(Int(Rnd() * 10))
        Label3.Text = CStr(Int(Rnd() * 10))
        ' if any number is 7 display picture and beep
        If (Label1.Text = "7") Or (Label2.Text = "7") _
        Or (Label3.Text = "7") Then
            PictureBox1.Visible = True
            Beep()
        End If
    End Sub

    Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Me.Close()
    End Sub
End Class

oh by the way, do you guys know of any resources where i can get VB.net command references from, like today i was wondering how to actually close the form i created when you click on the edit button, luckily a friend of mine knew what it was and i got around the problem but i was just wondering where to get a complete command reference from.

As wtd said, MSDN is a good reference. As for forums, here has about 1.3 million posts and here has about 2.4 million posts. You're bound to find out info on problems you're having.

Also, if I may, unless you are constrained to using VB.NET by a class you're in, then I strongly suggest you use C#. It's the same library, but just so much nicer a language in which to use that library.

Oh, and try naming your variables meaningfully. "Label1" is a really bad name for a variable. What does it label?

For instance, let's say it labels an input field where a name is input.

code:
nameInputFieldLabel

As I recall, VB follows a system like so:
code:
txtName - Textbox
lblName - Label
frmName - Form
modName - Module
Well, you get the point. Now if you'll excuse me, I'm going to go try to forget all of this VB stuff before I go insane.

ya bro, actually ive been looking over c# and a friend of mine gave me all his notes, assignments and everything from his first,second term learning C#, so i got all my resources, i wanted to learn VB because my teacher is going to be teaching it soon and the idea of programming a language with primary GUI based stuff sounds cool, i have never done C# though, when i was in india our computer teacher used to do random things, C++ one day VB the other so i have some memories on VB, like i sad earlier, i want to learn as much as i can when it comes to programming music and martial arts, but as of this moment, programming is my main priority, im doing good on the guitar and bass and i have my 7'th year black belt in kung fu and ninjutsu so thats going cool too lol..thanks for the advice bro, appretitates as always Very Happy

There is nothing about VB.NET that makes it better for GUIs than C#. As mentioned earlier, they are both using the exact same libraries. It's primarily the language then that is different, and of the two, C# is the better.

If your teacher is going to be using the .Net version of VB, then learning the .Net frameworks via C# will help you tremendously. If he or she is going to be using VB6, then you should know that VB6 and VB.NET are two entirely different languages, with only some superficial similarities.

i agree with you on that one, my friend is doing his MCSD in c# and he also told me that its much more powerfull then VB.Also, i think my teacher at school is teaching VB.NET but he wont be getting into it much, he will just teach basic forms and stuff and then we are on our own, just the same way it has been with java lol

Those may have been suggested with VB6. They are very much discouraged by Microsoft with VB.NET and C#.
