Glib shared libraries and debug problems
Hi, I have inherited a Palm app that is written as 3 parts, 2 GLIB shared library parts and the app itself and would like to debug this using the Palm OS Debugger. In the files window, I add the 3 executables (.prc) and then add the 3 'Symbolics' files, using the .o files generated by the linker. I then 'locate the directories' for each of the source files. I get to step through the main application code, but the 2 shared parts only show as assemlbly code, and the breakpoints I set do not work. After starting the app, the Low PC of the app changes to the load address, but the lib Low PCs do not. They remain as 'Sect(1) +0x' and 'Sect(2) +0x'. The Debug Console window shows just 2 sections loaded: Sect(3) and Sect(0). Can anyone point me in the direction of a tutorial or offer me some advice on how to integrate the shared libs into the debugger please. Thanks in anticipation.

Subject: Scrolling Fields
I'm trying to set up a field in my application that works with a scroll
bar. I have everything laid out but I am having trouble getting the field to
respond to changes in the scrollbar. The field just stays put or jumps all
the way to the end or the beginning when I attempt to move the scrollbar.
When I move through and edit the field the scrollbar responds perfectly it
just doesn't work the other way around. Here is the function that I call
when I receive the SclRepeatEvent.
Boolean MainForm::updateField(Int16 oldpos, Int16 newpos, struct
ScrollBarType * bar)
{
struct FormType * frmP = FrmGetFormPtr(Messages);
FieldType *field;
UInt16 fieldIndex;
fieldIndex = FrmGetObjectIndex(myForm, Messages);
field = (FieldType *)FrmGetObjectPtr(myForm, fieldIndex);
UInt16 scrollPos = 0;
UInt16 textHeight = 0;
UInt16 fieldHeight = 0;
UInt16 maxValue = 0;
const char * myChars = FldGetTextPtr(field);
fieldHeight = FldCalcFieldHeight(myChars, 140);
Int16 minimum = 0;
Int16 maximum = 0;
Int16 value;
Int16 pageSize;
UInt16 linesToScroll = (UInt16) newpos - oldpos;
WinDirectionType direction = winUp;
if(linesToScroll0)
{
linesToScroll = -1 * linesToScroll;
direction = winDown;
}
FldScrollField (field, linesToScroll,direction);
// Update the scroll bar.
SclGetScrollBar (bar, value, minimum, maximum, pageSize);

{
value -= (Int16) linesToScroll;
}

{

}

TonesLibPlayTone in AlmSetProcAlarm + Treo 650 CDMA == Crash
Here is the scenario, and it is very specificly on a Treo 650 CDMA
(Verizon/Sprint):
I use AlmSetProcAlarm to call a procedure at a specific time.
The procedure basically plays a tone over and over again, until interrupted.
e = SysLibLoad(tonesLibType, tonesLibCreator, nLibRefNum);
if( ( ! e ) (nLibRefNum != sysInvalidRefNum) )
{
e = TonesLibOpen(nLibRefNum);
if( ! e )
{
do
{
e = TonesLibPlayTone(nLibRefNum, oToneId, 1, toneVolume5,
toneVibrateNone, true);
if( ! e )
{
if(EvtSysEventAvail(true))
{
e = sndErrInterrupted;
} // if(EvtSysEventAvail(true))
} // if( ! e ) from TonesLibPlayTone
} // do
while( ! e );
TonesLibClose(nLibRefNum);
} // if( ! e ) From TonesLibOpen
SysLibRemove(nLibRefNum);
} // if( ( ! e ) (nLibRefNum != sysInvalidRefNum) ) from SysLibLoad
Everything works fine until the tone is playing, and a caller calls into the
phone, and then the caller disconnects (not the callee) before it is answered.
When this happens, the screen stays up that the call is coming in, and I can
switch between the anser/hangup buttons...but when I select either of them,
nothing happens. I have traed into the code, and it goes into
TonesLibPlayTone...but never comes back out.
Any ideas what I might be doing wrong? The Attention Manager does not seem to
have this problem, so I assume I am doing something wrong...
Thanks for any help.

Re: No of records
My question on how many allocations should have been restated to ask What is the maximum total heap for a given application I'm not clear as to whether 64K is the total heap for a given app or whether its the largest single call one to make to allocate memory. I'm using malloc,free right now which I think in CodeWarrior is mapped to MemPtrNew, MemPtrFree and probably the same in GNU. I'm hoping this depends on the Device, an 8MB device would presumably over more usable heap than a 4MB device. Is MemSemaphore* functions are supported in all m68k devices. I'd need read/write access for the algorithm and would use heap for that as it would be variable. I can't seem to find any informationon MemSemaphore in Rhodes, McKeehan or Foster. Is this a 68K Palm OS function? Evidently this is a trick to get more memory and treat as dynamic on the Palm. What OS has this function, 3.5 and above. If I were to allocate the following blocks on a Palm would it be a problem? 12K 50K 15K 36K 16K 25K 62K Would the Palm let me do all these allocations in a single program run? Thanks for your help.

Re: No of records
As of OS 3.0 I believe that the maximum size record is just a bit under 64K. I don't recall the exact number but I believe it not exactly 64K, just under. Also the maximum heap allocation is 96K but TCP/IP stacks take up 32K so back down to 64K as a maximum allocation size. I believe this is accurate for the motorolla 68K Dragonball but not sure about the ARMLETS. Let assume the dragonball model -the questions remains ? How many allocations of about 64K can one do? ? What if I need to load an entire record, is it possible to load all that data, about 64K into a dynamically allocated buffer If I were to say parse XML, would it make sense to load as much as I can into memory and operate on that for speed or should I iterate the data directly w/in the storage heap? --- Roger Stringer [EMAIL PROTECTED] wrote: At 04:17 AM 7/21/2006, you wrote: Subject: No of records From: Jagat Nibas Mahapatra [EMAIL PROTECTED] Date: Thu, 20 Jul 2006 15:06:33 +0530 What is the maximum number of records I can create in a palm database ? Palm OS databases can have up to 64K records and each can be up to 64KB in size. Having said that, most people try to keep the number of records less than 16K, for reasons that having been much discussed in the archives. Do remember that Palm OS databases aren't databases in the normal understanding of that word. Also you can view the records as variable length blocks into which you can stuff your records. Using blocking techniques, you can achieve very large record counts. For example I have some library customers with over 200,000 records. So if your application has low to moderate record counts, just treat the records as records. But if you have high record counts you'd be strongly advised to implement blocking techniques on those databases. Roger Stringer Marietta Systems, Inc.

You can try to break up your application into 1 or 2 shared libraries to reduce your 64K segment limit. You call these shared libraries w/o concern over segment issues. A good tutorial is found in the MathLib.prc web page. Just google for it. --- [EMAIL PROTECTED] wrote: I have a background application, which has no UI whatsoever, that has unfortunately grown beyond the 64K segment limit. I need to figure out some way to call code accross segments, without being launched with sysAppLaunchCmdNormalLaunch. Specifically, I need to find a way to launch myself with globals, and not trigger any UI at all (i.e. SysAppUISwitch is not an option). I'm using Codewarrior 9.3, and targetting PalmOS 5.4, specifically the Treo 650. Here's what I understand: - You cannot call anything out of your first segment on a no-globals launch. - The above is true, no matter what magic you use in Codewarrior (e.g. expanded mode doesn't help). - You cannot call yourself using SysAppLaunch and pass sysAppLaunchFlagNewGlobals, as that will eat up an owner ID every time you do it. So, do I have any options at all here? Is there any way to get my app launched in a context where I can call other segments, short of SysAppUISwitch? Surely there is a way to do this.

popup list pops up twice instead of once
Hello, I have a popup trigger with a listID of a list that is dynamically created and doesnt exist in the resource. I call LstNewList and associate it with that trigger, set my draw function, LstSetListChoices with NULL for the text array pointer. I have my main form event handler return false by default, and right now it only handles frmopenevent and popselectevent. My popup handler switch/cases the popup trigger id and returns true after updating the control label and the lstsetselection. My problem is that after I tap on the popup trigger and then tap on my selection, the popup list disappears and immediately appears again where I have to tap again and then everything seems to proceed normally. Please tell me what I am doing wrong. I searched all the source examples and I dont see lstnewlist anywhere in the source for os5.

RE: PODS - killing errant Palm Simulator
I guess you can get around this by when you need to start your debugged application again, terminate your current debug session or whatever and then right click and go to hard reset of the simulator. Then start debugging again... This way you never need to close the simulator, and when you crash it it dies fully.

some questions using lists
Hello, I have a few questions regarding the use of lists. Is it possible to have an effective list that responds to a table tap, without using a special popup trigger? Is it possible to have a table row as a popup trigger? I have a table with one column and I want a user to be able to click anywhere within the column and have a dynamic list pop up. I create the list and then I thought that I should loop catching events and on each iteration continue only if the pen tap is within the bounds of the list. I'm not sure on the best or the Palm Blessed way of doing this. Right now I pop up the list and a user can click on a table row and that will cause a new list to be created. I didn't see any event that would let me figure out that there was a tap outside of my list. I see lstExitEvent, but that happens when I tap within the list, nothing special happens regarding the list when i tap outside of it.

Treo 650 Phone Call Information
First, I am using a GSM Treo 650 on the Cingular network. Problem: I would like to get the caller id information for the currently active phone calls on a Treo 650. By caller id information I am referring to phone number (dialed if outgoing, or the incoming number), contact name, phone call start date/time. Attempted Solutions: I have successfully registered and caught the phnLibLaunchCmdEvent, and then retrieved the phone number when the event type is phnEvtSubscriber. This is a start, and I could use the current system date/time as the start date/time of the phone call. I can stash these off in a feature and then use them if needed by my application. However I can not seem to ever receive an event in which the name fields are filled. To make this method unacceptable however is that for some reason when someone calls in via call-waiting I never recieve a phnEvtSubscriber for this second call. So I can get the basic info for line 1 via this method, but not for line 2. Preferrably my application could get this information on demand instead of catching an event and storing the info off. I have used the PhnLibGetPhoneCallStatus successfully to see that there is action, but I do not know the proper API's to call to get the caller id info for a specific line.

re: Camera Library Load/Remove and Invalid Chunk Pointer
Okay, Eventually found this one. The Codewarrior code was mapping the cmdPBP to the correct structure using mPowerCtx = (TmPowerCtx)cmdPBP which worked fine for the Codewarrior code but when this same structure was passed back in the callframe to SysUIAppSwitch it did not pass back correctly after the called application did a MemPtrSetOwner(mPowerCtx,0); SysUIAppSwitch(yada yada yada) On returning to the yada yada application it failed to correctly access the cmdPBP - it could actually read it fine but the emulator (bless its little cotton sox) threw lots of error reading unowned chunk type messages (that lazy slob simulator said nothing). Anyway, the simulator/emulator would finally blow a gasket when trying to exit this app. Solution was to: mPowerCtx = MemPtrNew(sizeof(TmPowerCtx)); MemMove(mPowerCtx,cmdPBP,sizeof(TmPowerCtx)); instead of mPowerCtx = (TmPowerCtx)cmdPBP; But I guess everyone else in the world knows this. rgds -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Camera Library Load/Remove and Invalid Chunk Pointer
Hi, Please bear with me while I explain a fairly complex (at least to me) setup which is causing an Invalid Chunk Pointer. I have one application (written in PocketStudio although I'm pretty sure that is not relevant) calling a second app (Codewarrior) which (in its simplest form) does a find library, load library, CameraLibraryOpen, TurnPreviewOn then TurnPreviewOff, CameraLibraryClose, SysLibRemove then does a SysUIAppSwitch back to the calling application. This all works fine but when I go to close the calling application I get an Invalid Chunk Pointer. This happens if I only load and remove the library (no camera library open/close) but does not happen if I don't touch the library in the called routine so it looks strongly like it is related to loading and removing the library. The remove library is not throwing an error. I also tried switching back to a different app but same result - the switch back works but I get the invalid chunk ptr on closing THAT app. I noted the lack of support for library loading on simulators but sadly I get identical behaviour on the device. Any ideas what further investigation I can do into this? thanks Andrew Waites -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

RE: Difference between NULL and 0?
Okay, the curmudgeon's gotta speak. Generally used to make a null pointer clear, NULL has been simply eye candy for the value 0. For twenty years, I've taken this interpretation as well. But recently, I've been finding places where a comparison against NULL gives different result than against 0, e.g. in pointer validation such as one would do when a function returns a pointer to a string. This sucks because I haven't figured out where it should be NULL and where it should be 0. I wrote my question after I had to check against BOTH to get the right behavior. By the way, in sdk-4, NULL is defined in stddefs.h as ((void *) 0).

Can you tell customer service is my dayjob? ;-) I will give this some real attention tomorrow (UK wind down time now) - but one quick question - do I need any specific glib files to make this all work?? The glib startup code is built into the palmos GCC development tools. If you hunt around in the library directories for GCC you'll find some .a files, I believe. This stub code is then included in the .a file for your library, and is in turn included by any application using the library. This stub code checks for the presence of the GLib on the device, opens it, and sets up a relocation table. It also satisfys GCC's need for valid function references. I'm not sure, but with a little work it should be possible to use GLibs with CodeWarrior - but with the advent of the new developer suite, CodeWarrior is becoming a little less important in the grand scheme of things. After typing 'make', and before typing 'make clean' (which removes excess temporary files, while leaving the .a and .prc), you'll find MyFontLib-jumps.s and MyFontLib-stubs.c (and corresponding .o files). Examine these. These files are the core functionality of GLibs! Note that the -stubs file is basically another representation of the .def file - in the GLib_myFL function is the assembly used to map each function in the library to the function /in/ the library (by number, which is why order is important in the .def file), the name of the library, the actual code to call each function, and code to arrange global access for the GLib. The -jumps file is the actual function/relocation table, which is mashed when the library is loaded for use in the application. (I think - someone correct me if I'm wrong.) Note that you may have difficulty compiling the font library if you don't have exactly the right version of pilrc... I just removed the fontfamily definitions from the RCP to get it to compile, but it won't run that way.

In MyFontLib (the Library):
1. Develop code, one (or more) function per file in Src, organized into
functional categories via subdirectories in Src. See SOURCES variable, line

(You /can/ use globals within the library - unlike shared libraries.)
4. Create MyFontLib.def, listing within the export{} section each exported
function, one per line. Do not delete old lines or add lines to anything
but
the end, otherwise you will break compatability with older versions.
(PalmOS
uses this, as can be seen by the V2, and V5 versions of some functions in
the
SDK.)
5. Compile using Make. This will produce libMyFontLib.a and MyFontLib.prc.
The PRC is the installable library, required for client applications to run.
The .a file is the developer library used to attach MyFontLib.prc to the
client application at runtime.
In LibTest (the Client):
1. Place an updated Library.h and libMyFontLib.a in the LibTest directory,
overwriting the old versions. These are the two files needed by each client
application at compile-time - and the only files needed. Once you link
against the library (-L. -lMyFontLib) you require not additional code to use
the functions within the library.
2. Develop code and resources for the client application.
3. Compile using Make - examine the Makefile in the LibTest directory. It
is
similar to the library's makefile and relies heavily on default targets.
4. Load up the two PRCs into an Emulator or Simulator. Enjoy.
General Notes:
1. You'll likely want to register your own creator ID for the library and
application, not to mention rename the entire library. In the library, you
need to modify Rsrc/Resources.rcp lines 5-7, Makefile line 1, and line 1 of
MyFontLib.def. Then rename MyFontLib.def to whatever you entered on line 1
of the Makefile. Delete the .a and .prc files, and the library should
re-compile fine. For the client application, update line 1 and 7 of the
Makefile, and lines 5-7 of Rsrc/Resources.rcp. Delete the .a and .prc files
and copy the new .a file from the library directory, and the client
application should compile fine.
2. Use functions from the library in the client application as if they were
functions built right into your client application. The font example uses
FntLibraryStartup on line 10 of Application.c and FntLibraryShutdown on line
26 of same. They are defined in Library.h, with actual code in the library.
3. Try writing your functions completely within the application, first.
Write
them in such a way as they do not rely on global variables presented in the
application (i.e. instead of using a global to store the current VFS volume,
pass it as the first argument). This will make debugging much, much easier,
as debugging (on PalmOS) libraries like this is damn near impossible. Only
when the functions work, perfectly, split them into a seperate library.
I am using palmos4.0 which appears in all my succesful builds cygwin
output.
For the broadest audiance, I do not specify a specific SDK version when
building. Try running palmos-dev-prep again to force it to set a default
SDK
(usually the newest), then compile again. Or, you can add -palmos4 to the
CFLAGS varaible in the Makefiles. (I'd reccomend the first, as you
shouldn't
need to specify a SDK version.)
I hope you get it to work with a minimum of difficulty,

RE: Glib - shared libraries [long] and now palmdev-prep
Hello again, I have searched everywhere for palmdev-prep (seems to be a useful tool!), however I cannot find it - yet again all help will be very appreciated. Cygwin just responds with command not found. Best regards Andrew Comley -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Matthew Bevan Sent: 16 November 2004 21:28 To: Palm Developer Forum Subject: Re: Glib - shared libraries [long] Howdy, Andrew! Many many thanks for that, you are being incredibly helpful! Thanks! Can you tell customer service is my dayjob? ;-) I will give this some real attention tomorrow (UK wind down time now) - but one quick question - do I need any specific glib files to make this all work?? The glib startup code is built into the palmos GCC development tools. If you hunt around in the library directories for GCC you'll find some .a files, I believe. This stub code is then included in the .a file for your library, and is in turn included by any application using the library. This stub code checks for the presence of the GLib on the device, opens it, and sets up a relocation table. It also satisfys GCC's need for valid function references. I'm not sure, but with a little work it should be possible to use GLibs with CodeWarrior - but with the advent of the new developer suite, CodeWarrior is becoming a little less important in the grand scheme of things. After typing 'make', and before typing 'make clean' (which removes excess temporary files, while leaving the .a and .prc), you'll find MyFontLib-jumps.s and MyFontLib-stubs.c (and corresponding .o files). Examine these. These files are the core functionality of GLibs! Note that the -stubs file is basically another representation of the .def file - in the GLib_myFL function is the assembly used to map each function in the library to the function /in/ the library (by number, which is why order is important in the .def file), the name of the library, the actual code to call each function, and code to arrange global access for the GLib. The -jumps file is the actual function/relocation table, which is mashed when the library is loaded for use in the application. (I think - someone correct me if I'm wrong.) Note that you may have difficulty compiling the font library if you don't have exactly the right version of pilrc... I just removed the fontfamily definitions from the RCP to get it to compile, but it won't run that way.

re: IR Toggle shortcut: Debugging complex IR exchange between handheld and POSE
Hi, This is a second, succincter, description of my needs I need to debug some IR communications and have gone beyond the capabilities of IR loopback. Has anybody used the following features on POSE: A) Infrared serial mode toggle (shortcut-.-s), about which the Knowledge Base (Answer #254) says, This shortcut toggles the output port of infrared data between the built-in IR port and the built-in serial port. This sounds like it would execute IR exchanges across the serial link. B) Serial port redirection to the PC's COM port (POSE Settings/Properties) should direct POSE serial output to a specific COM port. As far as I can tell, these shortcuts don't do what they say. I would appreciate any hints. Thanks, Andy -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
IR Toggle shortcut: Debugging complex IR exchange between handheld and POSE
Hi, I am developing an application that does a fairly complex IR exchange. I've debugged as much as I can on POSE with the IR loopback and now I need to move onto devices. However, I want to have access to my debug logs that POSE can provide so I would like to run my exchanges between POSE and a device. This should be possible, but I haven't worked it out. 1) I've set up an IR/USB dongle on the PC. I have proven that this works by enabling HotSync via IR and performed a HotSync across it. 2) I've converted the IR/USB data stream into a serial data stream with IRCOMM2K (see http://www.ircomm2k.de/). This is a virtual driver that makes the IR dongle appear to be a serial port. Again, I've proven that this works by enabling only serial HotSync and performing a Hotsync with it. This demonstrates that PC applications (i.e. HotSync) can use IRCOMM2K as a serial interface rather than an IR. With IR communications into the PC established this way, I then turned to setting up POSE to use this path in the reverse direction. This would seem to be two simple steps: a) Redirect POSE serial I/O to the PC COM port assigned to the virtual driver of step 2, above. Settings/Properties in POSE brings up the Redirection menu. b) The shortcut-.-s developer shortcut (goto http://kb.palmsource.com/cgi-bin/palmsource.cfg/php/enduser/std_alp.php and search for hidden shortcuts) will toggle IR I/O between the IR hardware and the serial port hardware. I have had no success at all with either of these. Doing steps a) and b) on POSE and then trying an exchange through the dongle with the handheld gives no activity. The IR toggle shortcut, on the device, seems to do nothing - if I do the toggle (so that IR goes to serial) I can still perform an IR HotSync. Have any of you successfully used the IR toggle? Of course, if you have any suggestions for an alternative approach to testing such exchanges, I'd surely listen.

T3 Calendar vs Datebook
Hi, Our app has a backup function which copies DBs to the SD card. This is used when roadwarriors lose their customer or product DBs. For completeness I've been also backing up the main Palm DBs (Datebook, ToDos, Memos, etc). On the T3 these PIMs have been replaced (sort of) with new versions and DBs but the doco (what little there is) indicates that the old DBs still exist (sort of - as in as some kind of write through pseudo DB) to support legacy apps. All seems to mostly work but we are seeing some nasty crashes on T3s when recovering DatebookDB from SD back to the Palm (using standard VFS calls). This does not seem to happen all the time - don't you just love that. I've not been able to locate layouts for the new databases. But could probably just work out if the app is on a T3 and back up only the new DB (Calendar) if that is all I need to do. Sadly, some other datebook related things are not all that happy. Our app does write to the Datebook and stores the RID of the Datebook entry so we can allow the user to manage our entries directly through the standard app. This now sort of works but not entirely - once again I suspect this has something to do with how the T3 interfaces to the old datebook format. So, any ideas where I can find some more info on what is going on here?

Tricky Things about WinDrawLine
HI All, In order to simulate a mouse drag event on Palm, the application has been design to use pen drag to resize a table's width. To achieve that, the problem is that we currently use 'WinDrawLine' to draw a vertical line, then use the pen to drag it horizontally. The background suppose to be same as before. But, actually, when the vertical line passed, the background even every thing on the screen include menu bar, has been removed. In order to skip the problem, we set 'WinDrawOperation ' to 'winInvert' mode(which is Bitwise XOR the color-matched source pixel onto the destination). Unfortunately, it does make sense.

Re: Database Vs Text files(Beginner)
Which sort of XML parser are you using? or you created your own parser alternatively? There's also a (questionable) trend toward using XML, rather than a CSV, as the intermediate file. A recent online webinar from Sybase iAnywhere and AvantGo featured their M-Server software which can send data between the server and a handheld using XML, either by cradle sync or wireless sync. Anyone who's seen XML knows it's big. Not only is bandwidth an issue, but on the device side, conversion from XML into a Palm database may be slow process. I do, however, like XML for its portable nature.

RE: Opinions on Expectation of problems with a known invalid global
Kevin, I think that the answer is that your testing may not reveal a problem, but somewhere, somewhen, somebody will find it. And it will happen when you are trying to make a critical release upon which the life of your company depends, or worse, upon which the life of a patient depends, given that you're doing medical stuff. Fix it now, when you can see it, when you haven't released it, when you still remember it. In your testing, your hardware and software configuration leaves your memory configuration in a place such that the global flag reference finds real physical memory. In another time (newer or older OS release) another place (newer or older hardware platform) another user (somebody with more/less software or hardware) the flag will be located where there isn't memory and you will crash hard.

Re: Handspring says delete third-party applications
Although this topic is getting a bit far from Palm development, I believe that we need to pay attention to this more than the latest tool or bug! First, has anybody written back to handspring in response to this newsletter? I believe that the third party developers are a critical resource for Palm and their licensees and Handspring needs to support our efforts. If they feel that we are doing a bad job, i.e. producing code that drains the batteries, then they should be on this forum showing us how and why that is the case. Otherwise I think they are just blaming us for poor hardware design. I don't have any evidence either way - are Handsprings known for short battery life? Gary Gorseline worried: Also, with PalmSource's new and recent licensing agreements and in some cases, lack of renewal of certain license agreements, gives me (personally) the impression that they are not considering the developers as a necessary part of their success. Look at the Zire and when China comes out with units under $50, how important is the developer segment to PalmSource, Palm or the licensees? I'm not sure I would interpret this news as necessarily dire. If I interpret your message correctly, I think that you're worried that the users of low priced Zires won't want to buy business applications. Perhaps this may be the case, but take a look at the PC market: I just bought a new Dell desktop for $370 (Open Box deal) and I will add software to it. Given that backdrop, I think that even $50 Zires will still want new applications. The $50 Zire will change the applications that we build. The market will be different and need different things. I'd invest in Ardiri.com if he started charging for games. There are other segments that could really make it when the community of users is huge, but I'll start taking food from my kids mouths if I say any more.

Incidentally, if you read the license agreement you got with the soft, and if it's been written by half clever person, you'll find that decompling binary code is forbidden :-( Of course, that may not apply to you, depending upon the laws in your county/state/country :) -- Andrew Francis [EMAIL PROTECTED] -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
Re: Can Palm Inc own the word Palm ?
Gary Gorsline [EMAIL PROTECTED] wrote in message news:56065@palm-dev-forum... If you have a product for several platforms, like CE and Pocket PC and Palm OS and Windows 9X, can you not advertise them as MyAppName CE, MyAppName Pocket PC, MyAppName Palm OS and MyAppName Windows. I'm pretty sure that it's legal to use names like MyAppName for Windows and MyAppName for Palm without infringing on the trademark. To determine whether a name violates a trademark, the main question asked is would the average consumer be confused by the naming? - and I think it's fair to say that your average consumer wouldn't look at MyAppName for Palm and get confused as to whether it was a product of Palm Inc, or equivalent to the Palm. There was a big tizz when Microsoft made noise about trademarking Windows, and I'm pretty sure that the general consensus afterwards is that names like Lotus 1-2-3 for Windows weren't in violation. That said, I'm not a lawyer and my memory is somewhat fuzzy, so go ask an attorney in your jurisdiction :) -- Andrew Francis [EMAIL PROTECTED] -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
Format of Datebook database
I'm trying to figure out the format of the Datebook database on the Palm, and I'm getting nowhere. All I've managed to find is source code for things that use the format (the sample Datebook conduit in the CDK, and source in the Coldsync and pilot-link utilities) - but while the code may work it's hardly clear on what exactly it's doing :) Searching the web and the knowledge base isn't really helping me either. Does anyone know of a textual description of the datebook format on the handheld?
