Hello,

I'm trying to use the commandbar control on a MDI Child in VB.NET.

I've got two commandbar controls:

- one on the MDI Container form

- one on the MDI Child form

On the parent, everything is OK. I can add commandbars, contextmenus...

On the child, I've a null reference exception as soon as I try to add something...

I'm using Codejock 19.1 and VS2017 (NET 4.7.2)

If I do this:

Dim test As TestForm

test = New TestForm()

test.MdiParent = Me

test.AxCommandBars1.ContextMenus.Add(500, "test")

I've a nullreferenceexception

If I do this:

Dim test As TestForm

test = New TestForm()

test.AxCommandBars1.ContextMenus.Add(500, "test")

All is OK

How can I use a commandbar on a MDI Child?

Thanks
