Hello, new to VB and I'm trying to use sample codes to see how the form runs once compiled. Each time I try anything though the form outputs blank... what am I doing wrong?

Sample code I used:

Module HelloWorld
Sub Main()
System.Console.WriteLine("Hello world!")
End Sub
End Module

What I have tried:

I've tried unloading the project and editing VB project itself; tried multiple sample codes, tried multiple basic formats...

What kind of app did you create? WPF, Windows Forms, Console, ASP.NET, ... what?

Forms apps don't use the console: they don't have one. They are very different from the Console apps you seem to be used to!

You can output to the console from within a forms-based app, but you need to run it in the debugger to see the output - it will appear in the Output pane, mixed in with threading (and suchlike) messages from the framework (and it's a better idea to use Debug.WriteLine instead of Console.WriteLine as they are automatically removed from production code).

Otherwise, to output messages in a Forms app, you need to add a Label or a TextBox to your app, and set it's Text property:

VB

MyLabel.Text = "Hello World!"

Do that in a suitable Event handler (perhaps the Form.Shown event) And you will be able to read it.
