JMMDI.VBX is a custom control for changing the background of an MDI
control.
This is Version 1.1 of JMMDI.VBX. The changes from Version 1.0
are that a GDI leak that could occur under certain cicumstances
was fixed and there are more options for positioning bitmaps and
icons.
In VB you cannot change the background of an MDI form.
If you use a window subclassing control, such as Message Blaster
or Message Hook, you can control the background through
the Windows API - err, well sort of. Using these controls to paint
the background depends on VB delivering events; something you cannot
count on. There are situations, such as while a dialog box is
display, where VB does not deliver events.
The solution to changing the background of an MDI form is a VBX. The
MDI effects control is visiable only at design time.
The files EXn.EXE are some samples of what you can do with the MDI control.
************************* EVENTS *****************************************
The MDI Effect Control has no events.
************************* PROPERTIES *************************************

the background is a solid. If it is 1 then the background color
