Referencing "Forms" objects from a module

Re: Referencing "Forms&quo t; objects from a module

your can easily find answer, in the following code

------------------------------------------------------------------------

Module Module1

Function A_Function()
MessageBox.Show (" i m in module1")
End Function

End Module

------------------------------------------------------------------------

Public Class Form1
Inherits System.Windows. Forms.Form

Private Sub Form1_Load(ByVa l sender As System.Object, ByVal e As
System.EventArg s) Handles MyBase.Load
Module1.A_Funct ion()

End Sub
End Class
------------------------------------------------------------------------

Re: Referencing "Forms&quo t; objects from a module

Almost.

The code snipit you provided shows the reverse.

You are referncing a module function from a form. I want to reference a form
object from a module. I have tried the 6.0 syntax which I described in my
original post - it's pretty much the same as the "form-to-module" reference
that you have illustrated.

How does one reference a form object from within a module?

If possible, don't use a Module. See previous discussions in this group.

Why don't you put the code in the Form?

That's just your personal opinion.

Re: Referencing "Forms&quo t; objects from a module

Paul you can do it by making the instance of the form in module like
shown below:

Module Module1

Function A_Function()

Dim frmInstance As Form1
frmInstance = New Form1

frmInstance.cal lMeFunction81()

End Function

End Module

* callMeFunction8 1() will be called which is in the form, Or you can do
what ever you want to do with it, as you got the instance of that form.

RE: Referencing "Forms&quo t; objects from a module

Paul,

You could pass a reference to the form to the code in the module.

Whom else's opinion should I post? It's not only an opinion but also a
suggestion.

Re: Referencing "Forms&quo t; objects from a module

When you say "objects ON a form", do you mean controls? If not, please
ignore this post. If so, though...

I would do this as a property of the form, exposing the object. This gives
your form control over itself, provides true encapsulation, and allows you
the ability to reject requests for the object, etc., etc. Directly
referencing the control is, IMHO, not the best programming practice for
these reasons.

In the form:

Public ReadOnly Property NameTextBox() As TextBox
Get
NameTextBox = TextBox1
End Get
End Property

In the module:

Dim mForm1 As Form1

Sub Test()
MsgBox(mForm1.N ameTextBox.Text ())
End Sub

Where NameTextBox is a descriptive name of your text box object, and mForm1
is an object that references your form.

One last thing... I have no idea what your application is, and I don't mean
to preach at all, but you may want to take the encapsulation concept one
step further and expose only values from your control, such as a property
that exposes the text value of a text box.

Absolutely not, in my opinion exact the right answer from Armin

To clarify this... :-)

It could be understood as: "Don't use a Module. That's the
conlusions of previous discussions.".

What I meant was:
"Don't use a Module. The usage of modules has already been discussed, so
look up the previous threads."

Thus, the last sentence was not to support my own opinion and give a (maybe
wrong) impression of what's the conclusion of previous threads, but it was
only to give a general hint to discussions about this subject (that also
mention advantages of modules).

(IMO, everything in a module is part of "*the* application". "*The*
application" is an object (singleton in this case) => "Class App" with
shared methods (my personal way of thinking only))

Re: Referencing "Forms&quo t; objects from a module

Huh ???

Well i guess it is your opinion , and it seems also to be Cor`s opinion so
Herrfried was right when he said that is just your opinion :-)

probably he said this, because if you read the comment someone might think
that it is bad coding practice to use a module at all

Ik zal het voor jouw in het nederlands doen.

Als het Armin en mijn opinion is, dan is het niet *alleen maar* de
persoonlijke opinie van Armin, maar een opinie van meer personen.

Translated.

I'll do it for you in Dutch.

If it is the opinion of Armin and mine opinion, than it is not *just* the
personal opinion from Amrin, however an opinion from more persons.

For the rest is real developping a going on traject where what was yesterday
right is tomorrow wrong.

The pleasure of Visual Basic Net is that it is not so commanding as other
languages. Because I have read many messages from you, is my believe that we
share that opinion.

But that's what I wrote in my previous post!?? I saw that it could have been
misunderstood - as Herfried probably did - thus the clarification.
