Is the treeview in the MDI itself?

Well, since you create the windows in FrameWndProc() upon receiving a NEW_DOCUMENT message, it should be fairly easy to get the handles to those windows, shouldn't it?

EDIT: I'm sorry, I was thinking C++ API.

But... give me some time to think aboutthe .NET solution.

I dont understand what u mean :S

anyway here is code that adds form names to treeview.

            for(int i = 1; i < this.MdiChildren.Length;i++)
                {
                        PrivMsg.Nodes.Clear();
                        PrivMsg.Nodes.Add(this.MdiChildren[i].Name.ToString());
                }

Still havent figured it out :S plz help

If you already have the nodes in the treeview, then it should fire an event everytime the user clicks on a different node. You don't need to create this event--it's fired automatically. You just need to handle it.

Before you add the node, I would pass i into the tag of that node, this way you can easily select the relevant MDI form when the node is selected instead of having to iterate through your forms looking for the one with the relevant name.

VB

Private Sub TreeView1_AfterSelect(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeViewEventArgs) _
  Handles TreeView1.AfterSelect
    Dim oNode As TreeNode = TreeView1.SelectedNode
    If (Not oNode Is Nothing) AndAlso (Not oNode.Tag Is Nothing) Then
    Dim iFormIndex As Integer = 0
    If TypeOf oNode.Tag Is GetType(Integer) Then iFormIndex = CInt(oNode.Tag)
    Dim Children() As Form = Me.MdiChildren
    Children(iFormIndex).Activate()
End If

C#

TreeNode oNode = null;
if ((oNode != null) && (oNode.Tag != null)){
  Int32 iFormIndex = 0;
  if (typeof(oNode.Tag) == GetType(Int32)){
    form[] Children = this.MdiChildren;
    Children[iFormIndex].Activate();
  }
}

That should be akin to what you're looking for - it may need some tweaking to do exactly what you're after.
