Re: How can the emulated program counter be changed?
program counter is PC register...it is a register (so you cannot set a watchpoint on it in the true meaning of the word). Furthermore it is written after every instruction is fetched, an so a watchpoint would be useless. and additionally how do you determine an unwanted write? pose warning translated into english is: you just attempted to jump to an address that can under no circumstances have executable code Best Regards, Dmitry Grinberg (847) 226 9295 On Sun, Mar 14, 2010 at 1:46 PM, Luc Le Blanc llebl...@cam.org wrote: Never mind.

Re: SCOOP: New GarnetOS (PalmOS) Handhelds Coming From Aceeca!
any specs? what cpu is being used (part nr), what sound/touchscreen chip? what pmu? [asking for obvious reasons: http://dgosblog.blogspot.com/] Best Regards, Dmitry Grinberg (847) 226 9295 On Fri, Jan 15, 2010 at 2:32 PM, David Thacker da...@pocketscience.cawrote: Here's some very interesting news for those of you still dealing in vertical/industrial markets: Aceeca is bringing several new handhelds to market in the next couple months, including models running the GarnetOS (aka PalmOS Garnet) operating system!! We've just been given clearance to release some info about the new devices: 1. MEZ1500 CE This device has been coming soon for almost 2 years, but is finally coming to market, scheduled for release the first week of March. This unit runs the Microsoft Windows CE 5.0 operating system. The MEZ1500 looks very similar to the MEZ1000, but features a QVGA colour screen, larger battery, side buttons, and additional wireless options compared to the MEZ1000. Of course, it features the trademark MZIO expansion port on the top of the device, for connecting barcode scanner modules, RFID readers, GPS receiver modules, and so on. It will support SD memory expansion also. We should have a MEZ1500 CE unit here for testing with Satellite Forms in a few weeks. List price on the MEZ1500 CE is expected to be $499, plus wireless options. 2. MEZ1500 Garnet Aceeca is working with ACCESS (formerly PalmSource) to load the GarnetOS on the MEZ1500, which will be the first PalmOS 5.x device from Aceeca. Running on the same hardware as the MEZ1500 CE version, the MEZ1500 garnet version offers a big speed increase from the MEZ1000, as well as the QVGA colour screen, twice the battery capacity, WLAN and Bluetooth options, SD memory expansion, and more. Aceeca expects to have beta units ready for testing at about the same time that the MEZ1500 CE version ships. Both the CE and Garnet versions of the MEZ1500 are built ultra-tough like their older brother the PalmOS 4.x powered MEZ1000. List price on the MEZ1500 Garnet is expected to be $499, plus wireless options. 3. PDA32 CE This is a brand new handheld that is smaller and less rugged than the MEZ1000 or MEZ1500 models. It is just slightly taller than a Palm TX, and about twice as thick. It has an ARM CPU, colour QVGA screen, but does NOT have the MZIO expansion bus, so it will not support add-on modules. It will have SD memory expansion, as well as wireless options. The first version of this device will run the Windows CE 5.0 OS. List price on the PDA32 CE is expected to be $199, plus wireless options. That is not a typo!! 4. PDA32 Garnet The same hardware as the PDA32 CE version, with the GarnetOS operating system! This will be the first new non-smartphone, non-barcode-scanner GarnetOS powered handheld released within the past couple years, with multiple wireless options and SD memory expansion. List price on the PDA32 CE is expected to be $199, plus wireless options. Amazing!! The PDA32 models are expected to start shipping in April.

Using, PrefSetPreference(prefRonamatic, 0x00); sets the associated Ronamatic action to null, but the swipe is still detected as 'the ronamatic stroke' and still no penUpEvent is sent.

I am pretty sure the computation on the buffer data is ok because I use the

Anlignment of the parameter 'parm' doesn't matter: the docs say the parameter
for the armlet needn't be aligned. I also checked that putting 'parm' on a
1,2 or 3 byte boundary does not cause a crash.

What we are seeing are seemingly random dmErrCorruptDatabase errors when attempting to open and/or close database(s) on the Tungsten E2. No problems on the Tungsten E or the newer Tungsten TX! Not surprisingly, this seems to almost exclusively affect the most dynamic databases in our application suite which are opened, accessed, modified (DmResizeRecord) or added to (DmNewRecord), and closed often, but maintaining and reusing the DmOpenRef has not seemed to help. These databases can become quite large, but not large enough, even with several other helper databases that could be open, to consume the 10MB of dbcache. Also, I have spent days redesigning the affected database in order to save results per user rather than per group of users in order to minimize the database sizes to, at the most, 300-400K, but this did not address the issue. Rather than a single dmErrCorruptDatabase error, I received several - one for each of several users - although not always on the same database. I've pushed this vast quantity of data through the emulator with no issues. Out of many thousands of deployed Palm handhelds (Tungsten E/E2/TX), *ALL* of the handhelds known to have this issue are Tungsten E2 handhelds, so it's difficult not to suspect this is an early implementation of NVFS issue. Can anything be done to address or work around the E2 NVFS problems - or is there something obvious I'm missing here!?

Re: Your opinion on creating registration for a new software
Hi,
I'm trying to create a registration system for a new software and I would
like to have your opinions on the following issues.
When you distribute your software to various sites do you provide
registration mechanism to them?
Not unless I trust them (that's a no)
At some point when the program checks for registration Key/File it will for
example set a boolean variable to true. Do you do it other way?
Yes, the main points are:
-inline keychecking func
-NEVER display any alert or dialog on correct/incorrect key being
entered, this is trivial to find
-use many many function pointers in structured for keychecking. Makes
it harder to follow the code.
-If your app is 68k, do a check if it's in the simulator/emulator and
in that case always be Registred to make it harder to use those
tools to hack it
Is it possible to check if my program is modified and prevent it from running?
Anything is possible :)
What Ryan suggested works, but is not too hard to circumvent. Instead
you can include RSA public key in your app's code section [preferably
obfuscated], and then sign it, storing the signature in a different
resource. Sign the app when you release. This way nobody can easily
re-sign it without having your private key. Also, do not refuse to run
if modified, and do not tell user app is modified, just run like it's
unregistered. This will have hackers chasing their tails forever. Also
when you do do the checksum, avoid doing things liek
DmGetResource('code',...). the constant 'code' will stand out in the
disassembly. Instead just do something like:
for(i = 0 ;i DmNumResources(myApps); i++){
uint32 type;
uint16 id;

Hello and thanks for responses,
at the moment the function that inits the global list items and variables is
storing around 50 * 20 strings, the chunk is allocated at application startup
and is set at 8kb (8192) as there was mention somewhere of granularity of the
nand.
therefore is not writing outside the malloc.
When the pointer being used to store either the locked MemHandle or the
MemPtr is displayed as a 4 byte numeral (in other words the address location)
after being declared and also just before the items are written to the chunk,
they are the same.
Still have not found a solution. The desk accessory cannot use globals, as no
desk accessories can, although there are a few methods around this, Ftr
memory, prefs, a typedefed global struct, etc.
something like so :
in included header
typedef struct psuedo_globals {
// form
Int16 X;
Int16 Y;
Int16 W;
Int16 H;
// pen detection
RectangleType P[MaxPenDetectAreas];
// DeskHandler
Coord x_DIFF; // form move coords
Coord y_DIFF;
Coord x_STRT;
Coord y_STRT;
Coord x_SAV;
Coord y_SAV;
// etc., etc...
}psuedo_globals;
then in the main.c for the desk accessory would be something like:
//
//start
Int8 start(void){Deskmain(); return 0x00;

I usually get crap written to the BitmapPtr and when I draw it with

Does anyone have a clue why my code keeps crapping out like this?

Re: forum heart beat check
Isn't it great how nowhere in that [COMPLETELY CORRECT] explanation of how things work now there is any mention of the users and what they want :-) ? But I think all of that is moving into the past. The current marketing paradigm is to sell services that use air time. We don't need to synchronize -- we just need to send messages over the air. This may be part of the reason that WebOS is so oriented toward HTML/JavaScript -- the more air time used to send data back and forth, the more money the mobile service provider gets to bill for. They can afford to sell the devices and even the applications as loss leaders providing that they can use them to increase the revenue stream for the mobile service. -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/

Re: Is it possible to disable or enable some functions of Dia?
That SDK is useless, since OS randomly resets DIA state and what is
allowed and not allowed (collapsibility, rotateability, orientation)
as long as you are guaranteed to be running on OS 5.4+ the best way is
to manipulate the fields directly. This causes the DIA to not jerk up
and down. and allows some stranger states to be set in per-form
manner. Eg a form's dia policy can be dia always up, form always
shown in portrait, rotation disabled collapsing enabled) this means
that when form is shown device will rotate to portrait alwasy, open
dia, but allow collapsing and disallow rotation. The parameters are:
orientation: {port,land,rev port, rev land}
collapsibility: {yes, no}
rotateability: {yes, no}
original dia state: {up, down}
thus making for 32 combinations.
If anyone is actually interested, I can share the info

As for preventing rotation look around. Just make the forms you want to be

I certainly won't be following Palm into the great beyond this time. Personally, the next version of my software will be running on Android. I choose it because it is very likely the next PDA-ish/PDA-capable OS I will be using myself and because the user base can only grow for the forseeable future.

Furthermore, there are crackers out there, perhaps most of them, who do it because they find it personally rewarding, or for status in their subculture. The harder it is to crack, the greater the status from doing so. Music and movie companies spent millions developing content protection system that were broken in weeks or months. And when cracked once, your app is available to anyone willing to use a cracked version. One can divide users in to three categories: those saints who will pay regardless of what measures you take, those freeloaders who won't pay regardless, and the largest group, those who will pay if that is a better experience than not paying. Most people value being able to think of themselves as honest. They want the software to be easy to install and use. They want to be able to update easily when bug fixes come out. They want technical support. They expect their software to run when they get new hardware. And they don't want to pay more than a fair price for it. (Ideas of what constitute fairness differ.) So, you should evaluate every protection measure against the question Does this make it a better experience to pay, rather than not pay?. So, if users must do complicated things to activate their software, it tilts the equation against you. Making it easy to obtain tech support if you have paid, and hard if you haven't, tilts the equation your way. Making easy for paid users to upgrade to a version with new features, vs. waiting for the the new version to be cracked, tilts the equation in your favor. As a citizen, it may advance the social good to deny software to people who won't pay for it, but as a businessman, you shouldn't care -- if they won't pay, there's no profit to be made, and it doesn't cost you anything. The easier it is to plug a security package or library into an application, the easier it is for crackers to unplug. So, if you're serious about technical protection measures, it needs to be intertwined with the functioning code. You need to implement a system where you can vary the protection measures with each release, so it can't be cracked the same way as previous releases. The cracker community has spent thirty years developing its tactics and tools. Inform yourself before expending effort on technical protection measures. One area that does pay off is making it difficult to generate valid license codes. Then, at least black marketeers can't sell licenses for your software that work with uncracked software. A license code is like a message from the publisher saying 'it's okay to run given such-and-such environment'. Public key cryptography can make it near-impossible to fake a message -- if you dot all your i's and cross all your t's. But keep in mind what you're locking the software to. Palm OS devices don't all have unique hardware IDs, and most customers expect to be able to take their software with them to a new model. You can expect that HotSync names are effectively unique -- but there are hacks to change the HotSync name before any given app executes, so anyone willing to cheat can use a published HotSync name - license code pair and still use their normal HotSync name for syncing. This is a simplified overview -- there are caveats to almost everything I've said above. But learn about the whole situation before expending effort. -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/

I have to agree. Historically, PDA's were useful as mobile data stores that could synchronize with a master database. Now that so many wireless devices have the ability to connect directly to the master db, there's far less need for the ability to store and sync. The other thing that made Palm devices and the Palm OS attractive was the minimalist Zen of Palm approach -- the application didn't try to be everything a desktop was because the technology couldn't support it. It's hard to compete with things like iPhones and netbook style PC's these days. More's the pity.

The only applications that are keeping handhelds going at all are satellite navigation and internet browsing. Although there are a lot of smartphones out there, they are being used very much as phones, and not as PDAs. People are downloading MP3s, ringtones, games and other small apps OTA.

Re: PenEvents and screenX, screenY - help please
I haven't programmed in 68k in a long while, but I am pretty sure this will do the trick: Err PenGetRawPen(PointType* penP) SYS_TRAP(*sysTrapPenGetRawPen*); this will get the RAW ADC outputs for the pen position (as much precision as there is) then you can use Then on that point you can call Err PenRawToScreen(PointType* penP) SYS_TRAP(sysTrapPenRawToScreen); which will convert it to 0-160 coords.

The API is a system only one called SysLCDBrightness. PLEASE in the name of
