Form Container

[shachar]

hi all.
in form1 i wrote:
dim MyForm2 as form=new form2

now i want to insert data to the property "id" of form2.
i wrote:
MyForm2.Id=3
but i get an error saying "Id" is not a member of
system...
how can i address the property of form2, contained by
form1?

Shachar,

Did you make on form 2 a friend or public field "ID"?
The most simple one is

Friend ID as Integer

in top of your form2 direct beneath the designer created code.

I hope this helps?

Hi Shachar

I'm assuming you've added a property called Id to Form2...

The problem could be your declaration (if you have Option Strict On).

You have declared

Dim MyForm2 As Form = New Form2

This means that you have a Form reference, not a Form2 reference - with
Option Strict On, as Form does not have an Id property, you can't access it -
even though the MyForm2 object has an Id property.

Two solutions:

1. Change the declaration to
Dim MyForm2 As Form2 = New Form2
or
Dim MyForm2 As New Form2
(Identical performance)

or turn Option Strict Off...slower, because now reflection will be used to
look up the property and set the value.
