Trivial, I know, but some people need to know these things.
From the start we have the header, appinfo (optional), sortinfo (optional) followed by the record entry headers.
The header is:
| Field | Size | Value |
|---|---|---|
| Db Name | 32 | Ascii Database Name |
| attributes | 2 | See DataMgr.h for meaning (dmHdrAttrResDB) |
| version | 2 | Version number an application would use this to decide if the content was compatible |
| creationDate | 4 | Creation date of the database – time from the palm epoch when it was created |
| modificationDate | 4 | Last modifiied date of the db. creationDate by default. |
| lastBackupDate | 4 | date last backed up ina hotsync |
| modificationNumber | 4 | when changed this gets bumped |
| appInfoID | 4 | Offset in this DB to the appinfo block (0 if it does not exist). |
| sortInfoId | 4 | Offset in the DB to the sortinfo block (0 if it does not exist) |
| type | 4 | the 4 character type of the pdb |
| creator | 4 | the 4 character creator of the pdb |
| uniqueIDSeed | 4 | Stumped – I don’t know what this is for, leave it at 0 |
| This is the end of the header structure, the next is the record entry information | ||
Record list:
| Field | Size | Value |
|---|---|---|
| nextrecordList | 4 | Address of the next record list (only used for really bit pdbs) |
| nRecords | 2 | Number of records in the recordlist |
| pad | 2 | Number of records in the recordlist |
| nRecords items | 4 * nRecords | Addresses of the records in the pdb |
The address of the first record usually lies immediately following the appinfo and sortinfo data. As this data is consumer defined, the only way of determining it’s size is to use relative calculations. For example, the size of the appinfo structure it’s local address up to min(addr(sortinfo, Address of any data records)) – 1. The size of the sortinfo structure is it’s local address up to the min(Address of any data records) – 1. They are application defined, and as such should not be messed with.
Hi,
SupressKeyClick Hack 1.04 crashes the Treo 650 upon radio on. 1.03 works fine as is. Thanks for treoclickhack 5, wish you could let the keyboard click while keeping the other click events silent.
Any chance of silencing the radio on/off sound? How about the insert/remove card sound?
