[RESOLVED] [2005] form not opening right

[onlyGirl]

I changed the MainMenuStrip property to menuStrip1 and since then, I've been having problems with the way forms open and close. On load, the form opens up half way instead of filling the whole screen. The window state is maximized but it continues to open half way. The first picture is how the form is opening and the second picture shows how the form is supposed to open.



Also, I keep getting an error message: Cannot access a disposed object.
Object name: 'Icon'. when I try to close the forms.

Can somebody please help!!!!????

The form is maximizing.... the panel is not.... try making sure your panel is set to Dock = Fill... or anchor it to all sides (I'd go with dock=fill).
As for the other error, with out knowing what code is running, can't help you. But it sounds like you're tryign to clear out an Icon for an object (presumably the form) after it's been disposed of.

I assume you have tried rebuilding your solution and closing and reopening the form designer window?

I don't have a panel on the form.

The code I am trying to run is

For Each frms As Form In Me.MdiChildren
        frms.Close()
  Next

did you add this menustrip1 to the MDI parent or the MDI child form?

as for your dispose error try this:

For Each frms As Form In Me.MdiChildren        
    if not frms.IsDisposed then
        frms.close
    end if
Next

[onlyGirl]

It is on the MDI Parent and no menustrip is specified for the rest of the child forms.

I will try your code, thanks!

I don't really have a reason why it is happening, but it appears to be some sort of bug.

How I was able to get it to work though, was to NOT set the child forms windowstate to maximized at design time (leave it as normal) but then when you actually create an instance and show the form, set it to maximized in code before showing it..

IE in the MDI parent:

        Dim F As New frmChild
        F.MdiParent = Me
        F.WindowState = FormWindowState.Maximized
        F.Show()

[onlyGirl]

ok, i will try that and see how it works for me. thanks a bunch!

That didn't work, I still get the same error message.

I did the exact same thing but the form just flickers multiple times and never opens.

This may sound stupid... but I'm going to ask anyways.... what's the border style for the form?

It's sizable. I'm going to kick myself if this is what is causing the error!

I changed it to Fixed single and it is working fine now but for some reason, when I added the mainmenustrip to the mdi parent, i can't close the child forms. It gets stuck on this:

[highlight = vb]
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing) 'gets stuck here when trying to close
End Sub
[/highlight]

[techgnome]

Interesting... I would have expected that to be the other way around... at least that part is solved.

As for the dispose problem.... don't know... .I don't normaly add the dispose code to my forms, so that's a little out of my element.
