1235.10Transparent bitmaps under VB4 32 bit ??CHEFS::geyzuh.reo.dec.com::Steve_MarshallMon Apr 28 1997 09:2920
Hi folks,

	I used to do this kind of thing all the time in VB3, utilising
	the example given in the VB3 knowledge base. I have since tried
	the code and it works under VB4 (16 bit), but does not seem to
	work under VB4 (32 bit). I had to change the API declarations to
	use the Win32 API library (GDI32) and to change the Alias for the
	GetObject routine to GetObjectA.

	Everything appears to run through without error, but there is no
	effect whatsoever.

	Does anyone have transparent bitmaps under Windows95 working
	(like the old VB3 example), and if so what other changes needed 
	to be made to the code ?

1235.11I take it that they don't work ...CHEFS::geyzuh.reo.dec.com::Steve_MarshallThu May 15 1997 11:077
	Can I take it, then, that no-one has transparent bitmaps
	working properly under VB4 32-bit?

	Steve
