Disappearing Listbox items...

[Kevin]

I'm using an ActiveX Listbox control in my Windows Forms program. I
can load the listbox and have it work fine on one of my forms. But
when I add the line:

Me.MDIParent = frmMain

the form appears with the items invisible. The scrollbar shows that
the items are in the listbox--I just can't see any of them.

If I comment out the above line, the items appear normally.

Has anyone else experienced this bug?

Kevin,

I think that few people can trace this this problem.

In my idea is normal code to create a mdichild from a mdiform by

dim mychild as new whateverform
mychild.MDIParent = me

I'm using an ActiveX Listbox control in my Windows Forms program.

I am curious why you are not using .NET's listbox control.

Because I need to be able to change the background color of each
individual item.

I tried using the Listview control and I get the same problem only
this time it doesn't matter if the form is a child form.

The scrollbar shows the items are there, they're just not visible (see
attached picture).

....I meant also that I need checkboxes. I'd like to use the
CheckedListbox control, but I need to be able to change the background
color of each item. I know I can do that with an "owner drawn"
listbox, but the checkedlistbox doesn't support this.
