Hey guys,
I am writing code to dynamically draw icons for an application launcher.
I am using a linked list to store all of the entries of the launcher, which
include both tAIB resource bitmaps (which are just BitmapType written to a
resource, right?) and generic BitmapTypes, all stored as pointers in my node
structure as a BitmapPtr icon.
When I attempt to copy the resource to a static location in memory using
newLink->icon=MemPtrNew( sizeof(BitmapType));
DmOpenRef ref=DmOpenDatabase(cn,id,dmModeReadWrite);
MemHandle h = DmGetResource( 'tAIB', 1000 );
if(h){
BitmapPtr oldIcon = MemHandleLock(h);
MemMove(newLink->icon, oldIcon, sizeof(BitmapType));
MemHandleUnlock(h);
}else{
newLink->icon=NULL;
}
DmReleaseResource(h)
I usually get crap written to the BitmapPtr and when I draw it with
WinDrawBitmap I usually get either a crash or just crap drawn to the screen,
I've yet to get a working icon.
Does anyone have a clue why my code keeps crapping out like this?
