Hallo,

I make a ATL COM project with support MFC, server type DLL.
I use Composite control as start dialog. The dialog have abck color
ambient and I can not set the backkolor gray.
Next problem. Next dialog is Miscellaneous Dialog. In this
I import OCX. OCX is treecontrol which co-laboration with database.
I can set, he is connected and he work good, but I can not services
he's event. I can mapping them bat they not call. The same problem
is when I wont mapping events in My class. My class is from CListCtrl
and events LVN_Onbeginlabeledit and OnEndlabeledit are not call.
