I am totally new with VB.NET...

I have a question here,
I first created a Form (Form1) and plant a TextBox (TextBox1) on it.
Then I created a Module (Module1), in this Module I have Sub Main()
Now I want to retrive the value from TextBox1, how would I do that?

In VB6 I would just do *something* like this:

Code:
Sub Main()
  Dim sTest as String
  sTest = Form1.TextBox1.Text
End Sub

But How would I do It in VB.NET?
 
[VB]
Sub Main()
Set frm1 to your form1
Dim frm1 as Form1
Dim sTest as String
sTest = Form1.TextBox1.Text
End Sub
[/VB]
In .net you need to dim each form agen.
//edit: sry if the code was incorect, did nog have a comp with vb.net near at that time

Er, that is partially correct. You need to create a new variable to
hold a new instance of the form, and then show the form using
Application.Run() (only in Sub Main, that is).

Code:
Public Shared Sub Main()
  Dim frm1 As New Form1()  A new instance of Form 1
  Dim sTest As String

  Application.Run(frm1)  The code stays here until frm1 is closed

  sTest = frm1.TextBox1.Text
End Sub  Now the program ends
 
I have absolutely no idea what youre trying to do, but I can tell you right now that that code will not do it.

1) You should not ever ever ever use modules, due to the fact that they eliminate the concept of OOP -- always use Shared procedures inside classes.
Code:
in MyClass.vb or whatever
Public Shared Sub Main()

2) You need to instantiate the instance of your form:
Code:
Dim frm1 As [b]New[/b] Form1

3) If you are using Sub Main(), you must manually start the main window message loop, using Application.Run(). After lines, put
Code:
Application.Run(frm1)
and the program will successfully start.

4) That last line,
Code:
sTest = Form1.TextBox1.Text
should be this:
Code:
sTest = [b]frm1[/b].TextBox1.Text
because you need to use the instance of the class, not the class itself.

At that point, it should execute... Once the program closes, the last sText line will execute.
