Have a look at the Palm File Format Spec document. The way DmCDFI and ExgDBRead know how big each record or resource is, except for the last one, is by comparing the offsets of adjacent entries in the list of headers. If your headers aren't right, these could differ by huge amounts - more than 64K. That would cause the record or resource allocation to fail, resulting in the error you're seeing. It doesn't matter how much space is available in the storage heap; such large chunks aren't currently allowed. A good way to debug this would be to put the pdb file you receive via HTTP into a single database record or resource. Then inspect this database using an on-device database viewer or by HotSyncing it onto the desktop and inspecting it there using a binary file viewer. You should be able to determine whether it's a valid pdb file by comparing it with the spec. If you can get the file onto a desktop, you can try dragging onto a Poser window. If it's malformed, Poser should complain. Note that DmCDFI is limited to (a bit less than) 64K total database size. ExgDBRead doesn't have this limit. -- Danny @ PalmSource -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
