Hi
Can't get my head round something which I reckon should be simple.
My app has a main form (frmMain). MdiContainer set to true.
A menu item triggers a new form (frmSelect) whose parent is frmMain
Button on frmSelect triggers a new form (frmReport) whose parent also needs
to be frmMain
When frmReport loads and displays I don't want user to see frmSelect, but I
don't want to close it.
When frmReport closes I want to re-display frmSelect so user can make new
selection for report or close Select form
My code so far is
On frmMain .......
Private Sub mnuItem1_Click( ByVal sender As System.Object, ByVal e As
System.EventArg s) Handles mnuItem1.Click
Dim f1 As New frmSelec
f1.MdiParent = Me
f1.Show()
End Sub
On frmSelect .......
Private Sub Button4_Click(B yVal sender As System.Object, ByVal e As
System.EventArg s) Handles Button4.Click
Dim f2 As New frmReport
Me.Visible = False
f2.MdiParent = ActiveForm
f2.Show()
End Sub
What do I need to put on the "closed" event of frmReport to get frmSelect to
become visible again. And have I used the best method of setting the parent
form for frmReport. I had to make frmSelect invisible to get the frmMain as
the active form to set it as the parent form. Otherwise a line "f2.mdipare nt
= me" was trying to set frmSelect as the parent for frmReport
Thanks in anticipation

Use f2.mdiparent = me.Mdiparent instead.
In frmMain, hold the references to frmSelect and frmReport in two fields.
Don't use the local variable f1 in mnuItem1_Click but the field in frmMain.
Same with frmReport: In Button4_click, raise an event notifying the
MDIparent that either frmReport has been opened, or that the MDIparent is to
open frmReport on it's own. If you do the former, pass the reference to the
new form along. In both cases, store the reference to frmReport in a field
in frmMain. Now that you have the reference, you can handle frmReport's
closing event. There you can reopen or reshow frmSelect. In addition,
handled both Form's closed event to set the references to Nothing.

Handle the "Closing" event of the forms, not the "Closed" event.

Thanks for this. The solution to setting the mdiparent worked.
I expect the main suggestion also works but I haven't a clue how to put
together what you propose ...... and I should know but somehow I've got a
mental block with forms in vb.net.
If I understand I should have two (invisible?) text boxes on frmMain? But
how do I get them to reference frmSelect and frmReport as you suggest. And do
I use these references to create a "new" instance of my form as I would with
"dim f1 as new frmSelect"
Sorry I know I'm being "thick" but since I tried to move from vb6 to vb.net
I just cannot grasp how to work with my forms..... even when helpful users
such as yourself point me in the right direction
Thanks for your help (and patience) so far

No, no textboxes. Variables at class level are called "fields": http://msdn.microsoft.com/library/en...ypemembers.asp http://msdn.microsoft.com/library/en...Properties.asp
What I meant was:
frmMain:
Private WithEvents ReportForm As frmReport
Private WithEvents SelectForm As frmSelect
Private Sub Button1_Click( _

End Sub

SelectForm = Nothing
End Sub
Private Sub ReportForm_Clos ed( _

I didn't pay attention on frmSelect being closed. Of course, this is only
one possible approach - such solutions are often very individual and depend
on many black horses.

Just to let you know I've finished coding with the pointers you gave me.
Only made one change .... added a line in "frmSelcect .... button_click" to
make the select window visible = false (rather than close).
Everything works as desired ..... AND, more importantly, I think I've
grasped a little bit more about how to handle forms in my apps.
Thanks very much for your help
