How to close Forms in a MdiContainer (RESOLVED)

[Novice]

Hi there,

i am a newbie in VB.NET and now I wanted to create something like a paint application. I have already made a Form containing a MdiContainer. I am able to open multiple new forms in this Container, but I'm unable to close them.

I've used the following code in the Close_Click Event:

Environment.Exit(0)

and

Close()

but neither of them worked.

Could you please help me out?

Thanks

Here is the code I'am using to open the new forms into my MdiContainer:

    Private Sub MainMenuFileNew_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles MainMenuFileNew.Click
        Dim frmNew As New Form2()
        frmNew.MdiParent = Me
        frmNew.Show()
    End Sub

Now how do I get the new Forms closed?

I don't think this is too much to a challenge, but too much for me.
Please help

All right, I've got it.

All you have to do is to write another 'Private Sub' which should be as follows:

Private Sub CloseSubForm()
        Dim ActiveView As frmSubForm = CType(Me.ActiveMdiChild, frmSubForm)
        ActiveView.Close()
    End Sub

Then you have to write the following into your 'Button_Click'-Event:

CloseSubForm()

Thanks anyway
