Thank you very much. I didn't know if the locked handle from GetResource
was JUST a BitmapType , or if it might have included other items...

Subject: Re: Format for bitmap resources?
You don't need to know the format to draw it:
VoidHand h = NULL;
BitmapPtr pBitmap = NULL;
SWord xpos = 10, ypos = 10; // default to up/left corner
file://- (bitmap) resource type
// note: there may be more than one tAIB resource
// w/ the same resid. In the Constructor 1.x terms,
// a "multibit icon" or a plain old "icon" both turn
// into tAIB resources, but w/ different properties
// about the bit depth. The OS gives you the one
// w/ the most bit depth when you ask for it.
if (!h)
h = DmGetResource( 'tAIB', resid );
file://- if we don't have it, we can't draw it!
if (!h)
return false;
file://- lock & load!
pBitmap = (BitmapPtr) MemHandleLock( h );
file://- some sort of problem locking it down, oops
if (!pBitmap) {
DmReleaseResource(h);
return false;
}
file://- draw it
WinDrawBitmap(pBitmap, xpos, ypos);
file://- clean up
MemHandleUnlock(h);
DmReleaseResource(h);
