Make MDIchild, not from MDIparent...

[decrypt]

This is what i have:

 

first i have a main form, and this is the only code in it:

 

    Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
       Dim frm1 As New Form1 
       frm1.MdiParent = Me
       frm1.Show()
   End Sub

 

That opens up form1 to be the mdichild of form 'Main'.

 

In form 1 i have this code:

 

        Dim chatD As New ChatForm
       chatD.MdiParent = frmMain
       chatD.Text = "Chat"
       chatD.Show()

 

The only problem is that the above code doesn't open it up as an mdiChild of form 'Main'. How could i make form1 open up chatform as an mdiChild of form 'Main'?

 

Thanks in advanced! :)

Is the Main forms IsMdiContainer property set to true?

yes, it is set to true...

Main is the MDI PArent - correct?

Form1 is a child of the Main form - also correct?

ChatForm is another child of the Main form - correct?

        Dim chatD As New ChatForm
       chatD.MdiParent = frmMain

Maybe the frmMain reference isnt working properly. I dont know how VB.NET handles references to forms using the class name (last time VB for me is VB 6 a couple of years back ;) ). frmMain is the form name, not the name of a variable containing the form. It could be that using this construction, VB creates a new frmMain internally, so the chatD.MdiParent refers to an object that is a second instance of the frmMain.

To work around this you would have to make sure you give the chatD form the same reference you use. That shouldnt be to difficult, I think the following would do that trick.
[code]
chatD.MdiParent = me.MdiParent

That would guarantee you reference to the correct form.

yes that is correct.
