Hi,

In vb.net 2002 and 2003 that will not reference the open form. You
need to have a reference to the form for it work or use the new keyword.

dim frm as new form

or

dim frm as form = me

Ken,

dim frm as form = me

I have not seen this one before.

Although that it is a little bit strange code, is it in my opinion a nice
one, it explains direct what happens.

Sry about my post, i made a typo, the code i have is as follows:

Dim frm as form1
frm.WindowState = FormWindowState.Normal

and the rest is still true about it being initialized and such, sorry for
the mistake

Probably you are searching for

Dim frm as form1
frm.WindowState = FormWindowState.Normal

me.WindowState = FormWindowState.Normal

If you have this kind of problems.
Set it in the designer properties and than open the designer created code.
That created code is mostly very nicely done.

I hope this helps,

kind of, i want to make the second form set to normal when the first form
closes, so on the "form closing" event, i have that code there

In my opinion is the most simple way to do that to make one of the forms the
owner than you can use in the other one

me.owner.windowstate = etc.

I hope this helps,

i did that and made each form owned by the main form, but then when i try to
say "me.owner.windowstate = etc" it gives the error again

How did you make it owned?

Cor

 

[Guest]

Dim frm As New Brackets
Me.AddOwnedForm(frm)
frm.show()

Iwdu,

I do it like this
\\\
dim frm as New Brackets 'assuming that this is a form
frm.owner = me
frm.show
///

I hope this helps,

i dont think the problem is with making it owner. i get the error at a
different time. i make form1 the owner of form "brackets", then in the
brackets form, when it closes, i try to have the owner's (form1) window state
be normal, not minimized and thats where i get the references error. this is
the code i use to try and change the window state:

Me.Owner.WindowState = FormWindowState.Normal

and thats the line i get the error on

This below works for me withouth any problem

\\\
Private Sub Form1_Load(ByVal sender As Object, _
ByVal e As System.EventArgs) Handles MyBase.Load
Dim frm As New Form2
frm.Owner = Me
frm.Show()
End Sub
///
\\\
Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) _
Handles MyBase.Load
Me.Owner.WindowState = FormWindowState.Minimized
End Sub
///

I hope this helps,
