HI,
I’m learning C# and already know VB .Net. I noticed that C# you have a
Static Void Main () (entry point of the app).
Well that got me thinking, I was told that VB.net removed “The Black Box”
of software (hidden code). Where is my Shared sub Main ()? When I create a
blank app and run it, it asked me where is Shared sub Main. So, can I assume
that it’s hidden on a win32 app? And if so, why hide it?
Thanks

Hi Andre,
Sub Main is an standard part of dotNet.
When it is ommitted as with VBNet in the standard way than that one is taken
in the Form you choose as startup in the properties of your application. It
is not a win32 part.
It is not hidden, you just do not have to use it, however when you want,
feel free to add that class a lot of VBNet programmers are using that as I
have seen.

What cor states below isn't exactly correct, or at least, isn't worded
exactly correct. Every .net application requires a managed entry point. (a
"shared sub main")
However, in a windows form application the vb.net compiler will
automatically create one for you if you chose a startup form. If you choose
a form named "Form1", the code it creates is :
<STAThread> _
Public Shared Sub Main()
Application.Run (New Form1)
End Sub
Note that this code is included in your application assembly, currently
pushed into the "Form1" type. So it's as if you had typed that exact code
above into your Form1 class and set Form1.Main as your startup method.
So no, it's not really hidden, it's just conveniently created for you if you
don't write it yourself. I personally write it myself when creating VB.net
winforms apps - it removes any ambiguity when looking at the code (you don't
have to check the project properties to figure out where the app starts),
and I can easily customize the startup code.

Just to add what Cor has posted, VB also has a weird quirk whereby if you
create an app, then go into the code module for the Class Form1 and change
the name to something other than Form1, you must then also go into the
project properties and tell if to use the new class name for the form as the
startup form. It assumes that it is still looking for Form1 and can no
longer find that class.
If you do not do this, you will get the error that Sub Main cannot be found.

Thanks All, I wish VB.net was alittle more like C# where the code is there
for you. Maybe have a check box to show or hide the code for those that don't

Does this show up in the code? I can't seem to find it. If I wanted to
write my own main to start the form, where would I put it? Just before the
class name?

Hi,
We have an application framework library that gets statically linked to any
applications we produce. (Windows apps, but I don't think that matters
here).
The framework is based heavily on the STL and the API uses many STL
constructs. Because of the static linking, and the fact that both app and
framework are built by the same compiler, we don't have any problems.
