[Andy Bell]

Hi All,

I am trying to download the ROM of a Tungsten T5 but it keeps crashing
after around 20% of the transfer.  I am using the Emulator on windows
and the Transfer.prc for the palm.
Any ideas?  Is there somewhere I can download the ROM?

Thanks in advance

Regarding PNG display....

[chinmaya]

Hi all,
Some developers suggested me about my problem but I couldn't do it .But I am 
really thankfull to them for their suggestion and  wish that they will help me 
in future.
I've already questioned before regarding this ,and as per suggestion I have 
done a lot but still I am waiting for result. May some mistake done by me.But I 
am not getting it.
 
So I am going in detail, so that some can help me exactlywhat I will follow 
...

Byte *dataSrc;
bytesRead = NetLibReceive(NetRefnum,socketRef,dataSrc,
   bytesRead,0,NULL,0,10 * SysTicksPerSecond(), &error);

Here the dataSrc is a buffer which is containing the PNG image in a 
compressed(may be )format and in byte order.
If compressed I need uncompress it and change it into a Image format, so that I 
can display it, but I don't know how to do it?
then I want to display on emulator.
As I am trying display on emulator directly, it is displaying some junk image 
on my emulator screen .
so please suggest what I will do?

Thanks in advance...

[Jeff Co]

Hello,
I'm a beginner and no programmer. I've made some changes to a prc file in Palm 
OS Developer's Suite (PODS) and now I want to save my project as a prc file. 
How do I do that?

This is the steps I did:
1. Start PODS.
2. File/New/ Project.
3. Choose Simple/Project.
4. Give a project name. (Let's call it XYZ)
5. File/Import/Palm OS Resource File
6. In "From Resource", I browse to the prc file on my hard drive. Click Finish.
7. Make some changes.

8. *** now what do i do? 

What is this final step to package the project into a prc file again?

USB debugging on T|X

[Doug Gordon]

I was finally able to debug on my T|X and, even though this has probably been 
discussed before, I thought I'd summarize what I did.

First off, I was able to put the T|X into console mode with the shortcut-dot-2 
sequence. This was working all along, but I had forgotten that the only 
indicator is that blinking pixel in the lower right corner. So I was OK there.

The real problem was that my CW9 was not able to access the USB port. Guru Ben 
Combee wrote a KB article about putting the USBPort.dll file into a different 
location, but what he wrote was a bit confusing since he said to use a folder 
under "My Documents" that I'd never heard of. The more accurate solution is to 
say to move that file to your Palm Desktop root folder, wherever that happens 
to be. I have not changed my Palm folder since I started out with my IIIx, so 
it is still C:\Palm for me and I have always upgraded into that folder.

The other apparently important thing to do is to *move* the DLL there, not 
simply *copy* it. My USBPort.dll was in the Win/System32 folder, so I moved it 
to C:\Palm and rebooted to get everything cleaned up. So now CW9 and Hotsync 
are both working correctly, talking to my T|X (but not at the same time!).

Just thought I'd clear this up in case anyone else is having this type of 
problem. The other thing to note is that my need for this was due to the T|X 
itself behaving differently from the Simulator in regards to events posted by 
the 5-way control. The problem was easy to fix, but hard to see without the 
actual device debugging!

check out the 'u' option of par. :) (hint - look for par man page)

you can effectively do something like:

  mv KEYT_1000.bin KEYT03e8.bin
  par u file.prc KEYT 1000

or, something like that - i dont remember the syntax. i've had to do
this a number
of times and 'par' as a utility can do all these magical things easily :P

AFAIK, USB debugging on the LifeDrive doesn't work.  The LD uses a 
different chip to support USB 2.0 and I don't think the debug manager was 
hooked up correctly.

nonblocking and netInternalErr

I setup non-blocking and am trying to do a netlibreceive.  If i step through it

palm, i get netInternalErr.  I've tried playing with the netlibreceive timeout 
with no success.

Any Ideas?


do

bytesRead = NetLibReceive(netinfo->netlibrefnum, 
netinfo->socketrefnum,(void *)pBuffer, totalBytesToRead, 0,NULL, 
0,netinfo->timeout, pErr);

++timeoutCounter;

As we told you before:

You would need to convert it to bmp format to display it on Palm as Palm 
don't know png format only bmp. But there is no public PNG->BMP 
converter for Palm.


As you do not has competence to create a PNG->BMP converter what you are 
trying to do is *not* *possible*.


So is not possible for you to display a .png buffer image on Palm screen

Looks like the answer is no.

If you have to do it yourself, there are automated utilities out there that 
will do it for you.

You may have to hand fix the last 10% or so.

Take a look at this one:

http://www.amazon.com/gp/product/076457373X/
Professional Palm OS Programming.pdf
Lonnon R. Foster, Glenn Bachmann
WROX Press

It's less than a year old, and as far as I know,
the most up-to-date book on Palm OS Programming
outside of the official documentation.

The book covers both Garnet and Cobalt (not that
you want to know anything about Cobalt) and also
covers CodeWarrior and PODS.

Thank, I got this one - just forgot about it. And yes, except the (useless) 
Cobalt stuff that blows the whole book up, it's quite ok reading but I find
it a for-beginners rather than advanced (and the example Librarian app leaks ;) 
What I also forgot to mention is that I look for something  more advanced than 
"My helloworld.c". I found no up-to-date book covering i.e. palmos 5 color 
graphics, telephony etc - stuff that exists for years, but all we have is 
reference manual, some example codes from pluggedin (of which some simply crash 
my treo) and that's it.

Re: grey out for controls in palm

[Donald C. Kirker]

Hello,

You could probably create a custom function that will draw over the checkbox
with a grey line and then handle all screen taps to the checkbox (in the
penDownEvent) by returning true before the system has a chance to redraw an
updated checkbox over it.

Re: Regarding PNG display....

[Donald C. Kirker]

You can either use the code from PiNGer of the ZBoxZ project or port libpng.
Beware, this code is open source, so using it in your application will
require your application to be open source, unless you are willing to create
a png library. There are a few other programs that use this png code. Use
Google to find them, one is piv (Palm Image Viewer, a personal project by
some one) and the other is gps4palm (by the same person that does piv).

Re: Memory error

[Donald C. Kirker]

You are trying to write to an invalid memory pointer.

For instance, doing something like the following:

Char *myText = NULL;

StrCopy(myText, "This is text going to a NULL pointer");

You would have to allocate the memory with MemPtrNew (or MemGluePtrNew, or
even MemHandleNew) before using it.

This can also be caused my passing NULL pointers to system functions.

Dear future archive-reading newbie developer,
To be clear, this is NOT a licensing requirement of "open source"
software in general.  BSD-style licenses are open source, and do
not have this restriction.  ZBoxZ is licensed under GNU General
Public License, a form of "open source" licensing which DOES have
this so-called "viral" clause.

Palm programmers please help.

[valpetr]

Here is a situation: 
I need to decide on platform (tool, IDE) for Palm Pilot application development 
(currently PalmOS version 5.3).
The tasks:
1 – Application supposed to work on Palm based smart phone Treo 560.
2 – SOAP connectivity to .NET Web Service.
3 – Users have to be able to browse pictures.
4 – Application should not use build-in web browser.
5 – Application has to be able to be integrated with Mapopolis to determine 
position on the map and driving direction.

I’m currently considering Metrowerks Code Warrior, J2ME and Palm OS Developer 
Suite.
J2ME is my favorite so far but I never used it before and not sure how good 
support (documentation) for this tool is.
Any other ideas are welcome. 

Please explain briefly main pros and cons of the tool you think is best 
candidate for the job.

Please do not spread such false gossips. The term "Open Source" refers to 
software which both ensures the availability of source code and meets a specific 
set of criteria related to distribution of that software. You can learn more 
here: http://www.opensource.org/docs/definition.php Using open source components 
does not automatically means your app gets "cursed" and automatically converted 
to open source. What is important, is the license. Mind the difference and do 
your homework by learning how many various licenses open source can utilise:


http://www.opensource.org/licenses/ or 
http://www.gnu.org/licenses/license-list.html
http://sourceforge.net/docman/display_doc.php?docid=778&group_id=1

Also, what you should also understand and differce, is using shared library
in your app vs. linking statically the library with your app. This may be a 
slight difference for the app from the code point of view, but it do matter

as for license (hence i.e. GPL and LGPL). So to clarify the thing, as there's
not the place for such debate - you shall always read the license of the 
software (opensource/closedsource/free/commercial), especially if you want

to use it in your applocation or get "inspired by" its source code.

As for libpng - you really should have spent 3 minutes reading its license
prior sending your former post: 
http://www.libpng.org/pub/png/src/libpng-LICENSE.txt

[valpetr]

The fact that I never used J2ME does not mean that I never developed Palm 
application or never used Java for development (windows apps, web apps).
The reason why J2ME is #1 in my list because it is tool (well, environment) 
that allows to use object libraries VS CodeWarrior that does not (the attempt 
to include POL into the version 9.3 is miserably failed)

Re: The resource file "XYZMain.rsrc" appears to be corrupt

[Logan Shaw]

Mike wrote:

more Palm Constructor 1.9 horrors!  the palm resource file for my app is
corrupt (AGAIN).  it opens with no resources and won't work until i restore
from a backup.  see how it looks when i open the file in attached GIF.

my wish is to know why this is happening and how to prevent it.

i hear that the constructor doesn't work well when the file contains more
than about 2700 resources.  mine has about 1000 (from the resource header
file) and is increasingly regularly going corrupt as shown in attached GIF.

   :
   :

what's the best way to make resources today for use with Code Warrior 9?

- had tried pilrc but it seems as frail as palm constructor.  maybe just bad
luck?  as i speak pilrc has about 30 access violation errors stacked up on


If I were doing a Palm project and there was no need to be compatible
with others developers' tools (or philosophies), I would lean towards
just using pilrc directly and editing the pilrc input file by hand
with a text editor.  Here's why:

1)  It takes a text file as input.  I'm pretty sure there's no reason
for it to open the file for write access.  Therefore, it's VERY
unlikely to trash your carefully-built resource input file.

2)  It's open source, so if it does crash on something critical, you
stand a chance of being able to fix it, rather than just wringing
your hands.

3)  Although having no visual editor might seem less productive, it's
a heck of a lot simpler, and if you're good with a text editor,
it might be just as productive in many situations, especially for
someone who (like me) has never truly gotten the hang of using
a mouse[1].

4)  Somewhat incidentally, text files are more compatible with many
source code control systems than one gigantic binary file is.

Of course, that's just my opinion.  By the way, when I've used pilrc
on Mac OS X (compiled from source), I've never seen it crash.  I
wonder if it's something about the Windows build or if it's an older
version (than 3.2) or something like that.  And if so, is it safe to
replace the CodeWarrior pilrc with your own?  I would think so, but
it's something to be clear on before you proceed.  :-)

  - Logan

[1] One of the things I've always loved about the Palm (other than
the streamlined, no-BS GUI) is that it has a pen instead of a
mouse.  It's hard to express how much better an input the pen
is.  Being able to indicate X and Y directly, rather than delta-X
and delta-Y as with a mouse, is infinitely superior because the
input you must give the machine to achieve your objective is not
a function of the pointer's state, which means you could literally
do it with your eyes closed if you wanted to.

Re: How do I read a Text file in Palm OS 5.4 ?

[Logan Shaw]

[EMAIL PROTECTED] wrote:

I am new to Palm programming, how can I place a Text file in the Palm and
read it through my application ? I am trying to make an applicaiton which
could read simple documents ( text files) on the palm.


As someone else said, text files aren't really in the Palm idiom.  If
the goal is to create something that works with text files that exist
independently of the Palm, then it's worth pursuing.  But if the text
file is only to exist on the Palm, it would be better to use database
records instead of a text file.

Anyway, if you determine that a text file does make sense, then you have
a choice.  In the early days, there were no SD Cards, and the only way
to have a file was to encapsulate it in a database.  This is called a
FileStream.  To the user, it looks like any other PDB, but it has a
structure where you can use FileOpen(), FileRead(), etc. to read and
write it on the Palm.  This method will be compatible with all but the
very oldest Palm devices.  (I think File Streams were introduced in
version 2.0 or something.)

The other method, now that there are SD Cards, is to assume that the
user does in fact actually own an SD Card, and force them to put the
file on that card.  Then you can use VFSFileOpen(), VFSFileRead(),
etc. to read and write it.  VFS files have names a bit more like
what you're used to, in that they're in a hierarchical namespace
and all that.  (File Streams are in a flat namespace, because they
are really just databases.)

The thing to be aware of with all this is that there is no built-in
set of buffered file I/O routines (like stdio) on the Palm.  That means
that if you want routines to, say, read a line from the text file, you
will have to supply them[1].  When I added a feature to one of my apps
to spit out a text file (HTML, actually) summarizing data the user had
entered into the application, I basically ended up writing my own
equivalents of fopen(), fclose(), fputs(), fputc(), putw(), fflush(),
etc.  It worked fine and was, surprisingly, not all that painful, but
it did take time...

  - Logan

[1]  There is such a thing as a Standard IO Application on the
 Palm, but changes the entire structure of the app as I
 understand it, so you can't just add this on to your
 existing app if you need to add the ability to read and
 write text files.

Too many clicks

Well excuse my ignorance. Since working on an open source project this was

look it up. Plus, I was refering to PiNGer, which is part of ZBoxZ. When i
said open source I meant GPL.

Do you have to put it in base64 encoding or (more commonly) do you need
to create a MIME-formatted message?

Either way, here is the relevant documentation on creating a MIME-formatted
message (which can use base64 but can also use other transfer-encodings):

http://www.ietf.org/rfc/rfc2045.txt

Section 6.8 (which is on p. 24) is the part about base64.

If all you have to do is write some data in base64 format, it probably
won't be that hard.  You just need to do some bit shifting and define a
lookup table that specifies which characters represent each of the 64
possible values.  The document above spells it out in full detail.
