I am testing a VB6 application for compatibility as we move to Windows 7 64-bit desktops in 2014.
I have noticed something that is very strange and can't work out why it's happening.
When I open certain child forms in my MDI interface, the application MDI window disapperas, and is also not in the Task List in Task Manager. The child form that I opened is fine, I can interact with, use global ADO connection variables and settings variables that are in the scope of the MDI parent, and I can do db changes.
When I close the child form, there is no MDI parent/ application windiow, and I have to clsoe the process using Task Manager.
Here is the code used to open the child form (from a menu in the MDI parent):
Here is the form load event handler in the child form:
Has anyone seen anything similar happening with VB6 MDI applications under Win 7 64 bit?
Any thoughts on what I can do to prevent this - is there any documentation from Microsoft about this?
thanks
Philip
