Hi,
I hope someone can help out here.. I've been beating my head on this problem
for far too long.
I need to create a dynamic bitmap and store it in a resource DB. The problem
is that I have a pointer to the bitmap, and to stuff it in the resource DB
with something like DmAttachResource, I need a handle.
So, I tried to use DmNewResource - ultimately got a pointer - and then tried
a MemMove from my original bitmap to the bitmap in the resource DB. I get an
error with that approach - attempt to write to memory location which is in
the storage heap - such direct access is not allowed - should use special
Palm OS functions for this purpose.
See code snip below...
Can someone tell me what function I should use? Or is my approach completely
flawed to begin with?
Thanks,
Ellen
Code snip:
// create a new entry in resource db for bitmap
bmH = DmNewResource (bm_dbR, 'Tbmp', 3333, BmpSize(bmpP));
if (bmH) {
// now copy the bitmap in...
// lock it ..
resBmpP = (BitmapPtr) MemHandleLock(bmH);
// attempt copy ... this doesn't work
MemMove (resBmpP, bmpP, BmpSize(bmpP));
// draw it on the current form
frmP = FrmGetActiveForm();
FrmNewBitmap(&frmP, 3333, 3333, 50, 100);
// unlock it
MemHandleUnlock(bmH);
}
