Form showing then vanishing?

[Adam Honek]

Hello,

I have an app that starts in sub main()

I am making a new instance of a form so it can be displayed. It compiles
fine but when
the program is run the form shows up but then a split second later closes
itself.

Why is this?

Code below:

Public Sub main()
Dim MyNewForm As New AccountsForm

MyNewForm .Show()

End Sub

Thanks,

Adam

Replace the line above with this one:

\\\
Application.Run(MyNewForm)

ShowDialog() seems to work too.....

'ShowDialog' is semantically incorrect in this particular case.

Adam,

Why you use sub main.

I have seen yesterday that Crouchie has the same idea as me about this.
(Can be that he was that much longer however I saw a message about this from
him yesterday)

AFAIK was Terry(Ohm) that already.

Change it like this:

Public Sub Main ()
Application.Run (New AccountsForm)
End Sub

Is something wrong with using Sub Main? VB.NET trys to hide it - but, I
use it a lot for things like checking for a single instance, etc. Of
course, I do all my real programming in C# anyway...

We are active in more newsgroups, therefore I know what language you are
using at the moment.

However why use archaic sentences, if there is something nice built in.
(You would probably have seen, that I am always asking to people why, who
want to translate, what they are used to do in the past, in a newer
languages).

My standard sample is from far in past, when somebody told that Cobol was
much slower than Fortran. He had a translated Sort from his Fortran program
in the same way in Cobol.

He did not know that there was a Sort method already from the first versions
built in as feature in the Cobol language.

(We know that this is bs. the compiler on a particular OS or in that time
computer makes the performance)

In C# it is not built in (and when not using a form in VBNet as well not).
However when you use a form, than why not use that built in feature.

Just my thought,

Cor

I hope you understand... I still like VB.NET - I just don't have much
call to use it anymore. My employer has standardized on C#. Plus,
since I've been messing around with Linux, I find Mono a convenient
method of staying with a familar language - and right now, VB.NET
doesn't work all that well on Mono (but it's getting better).

Well, it actually is built in to Visual C#. When you create a windows forms
project in C#, a default Main is generated by Visual Studio - it just
doesn't hide it from you the way VB.NET does. I'm not saying to always use
Main by the way, but there are times when it is useful. I think of it as
another tool in the old toolbox :)
