Hi Zane,
For storing Resources(Bitmap) you have to create the DB as Resource
type. You have to give the ast parameter as True in the DmCreateDatabase ().
(i.e)
if (DmCreateDatabase(0, bmfileName, 'Blah', 'FntB', true)) return;
This creates the database to store Resources. Change the DmCreateDatabase()
and check.
