Customize Access 2010 64 bit ribbon with transparency icons

[Butteri Marco]

With Access 2007 I used the solution explained in
http://www.accessribbon.de/en/?Acce...ed_Icons___Pictures_In_Ribbon_Controls#basGDI
that use the API GDI.
In my new 64 bit version of Access the code doesn't compile: after the
instruction "Declare" the attribute "PtrSafe" is missed.
I've added "PtrSafe" but some istructions as "VarPtr" in 64 bit systems now
return LongPtr and not Long, so there is another error of compilation.
I've replaced the Long type used by VarPtr & Company with LongPtr and there
is no compilation error, but the the icons are not showed.
My System is Microsoft Windows 7 Professional.
Help please.
The module GDI is not necessary.
If possible I'd like to avoid creating mask images.
