Re: Blocking Alarms?

[Alex Robinson]

Scott,

I can say from bitter experience that you had better be in a very
controlled environment if you are filtering alarms. Or else you should
consider a 900 number to handle support.

There are *plenty* of programs out there with, ah, funky code in their
alarm handling code. The OS, itself (depending upon version and device),
is not without wrinkles in this area, too.

Consider that VII's use alarming for radio battery charging purposes.
And consider silent alarms from programs that do their updating in the
middle of the night.

Good luck.

Alex

What is the best way to track down a "Chunk Over-locked" error with the
CodeWarrior R5
running the current Palm OS Emulator?  Clicking on the "Debug" option from POSE 
doesn't seem to make anything happen.  I suspect there's a FAQ for this, but
Search on

As reported by cnet ( http://news.cnet.com/news/0-1006-201-4616749-0.html )
and other sources, the successor to the Palm Vx is "likely to be dubbed the
m505".

RE: Databases

If I understand what you have said,

1. You have a record structure like

typedef struct
{
  Char * Cliente;
  Char * NCliente;
} DatosCliente;

2. You have written records to a database, "TABLA" (but have not shown the
code you used, so we can't really know what is in the database).

3. You attempt to read a record from that database by querying a record and
casting the result to type DatosCliente.

If the above statements are correct, this can not work with the code you
posted.  If you have written records of type DatosCliente (as described
above) to the database, then each record you have written consists of two
pointers.  I think you wanted to write out strings of characters.

The normal method is to do one of the following:

1. Create a structure of fixed size strings and use that to write and read
from the database.  E.g.,

typedef struct
{
  Char Cliente[20];
  Char NCliente[10];
} DatosCliente;

2. Write two functions, pack and unpack, to convert your data to/from the
compressed format.  E.g.
to convert data from
a)  John Doe\0\0\0\0\0\0\0\0\0\0\0\012345\0\0\0\0\0 to
b)  John Doe\012345\0
Then you use format (a) in your program, but write out format (b).  When you
read the data in from the database, you convert back from format (b) to (a).

See Neil Rhodes book online for examples of packing/unpacking data.

Maybe you are writing to the database the wrong way (did you use DmWrite?).
Remember that the pointer that you get from MemHandleLock is a pointer to
database memory, which is protected.   I'm somewhat paranoid and doubt
CodeWarrior's competence, so I would do this:

for (...)
{
DatosCliente* p = (DatosCliente*) MemHandleLock(memH);
DatosCliente cliente = *p;

}

Alan, in the first place thanks for your cooperation. Here I will post again
some code that I changed according of what you said. I must remember
everyone that I am new, so please I just want a code snippet that Opens a
Database and Reads the Records through it. I show you this code in order to
show you that I try to search a solution but I cannot, it is not that I do
not want to do the work. Hope you and everyone can help,
Thanks

 static DmOpenRef  AddressDB;
 static LocalID  AddressDBID;
 static UInt16   nRecords;
 static Err   err;
 static MemHandle memH;
 static UInt16  i;


 AddressDBID = DmFindDatabase(0, "TABLA");
//I get a valid ID for the Database
 AddressDB = DmOpenDatabase(0, AddressDBID, dmModeReadOnly);
//I get valid pointer

 nRecords = DmNumRecords(AddressDB);
//I get exactly the number of records


 for (i = 0; i < nRecords; i++)
 {
   //here is where I have the problem, I do not know if I am doing this ok.
  memH = DmQueryRecord(AddressDB,i);
  Cliente = (DatosCliente *) MemHandleLock(memH);
//when I read Cliente->Nombre, it has anything except what I am looking for,
the same happens with
//Cliente->NCliente, I do not know where that value comes from, because it
is not the same as what the

  FrmCustomAlert(CustomAlert,Cliente->Nombre, Cliente->NCliente,"");

Is a value stored in AddressDBID? In other words, did your database get
found?

Is AddressDB not NULL?

> nRecords = DmNumRecords(AddressDB);
Does nRecords hold a value greater than 0?

God knows why you are allocating memory then not releasing it. Perhaps you
are later on but this isn't obvious.

>   Cliente = (DatosCliente *) DmQueryRecord(AddressDB, i);
DmQueryRecord returns a handle to a moveable memory location. The sequence
of events should normally be: Get a handle, Lock the handle to get a pointer
to your data type (struct, char, int, whatever you stored), use the data,
Unlock the handle, go on your merry way.

>   DmReleaseRecord(AddressDB, i, false);
As the documentation clearly says, use this on records that you've accessed
utilizing the DmGetRecord function. You didn't use DmGetRecord.

I just tried this out with Constructor 1.6b2, and I was able to reproduce
your problem.  I think the solution is to only save your resources when no
windows other than the project window are open, because otherwise you could
save a version without all changes committed.

Dave, could this be fixed for the 4.0 SDK?

Palette animation on Prism...?

[DIAMOND JEFF]

Unforunately, I don't have access to a real Prism yet, but from the dev
docs it seems that the Prism implements palette color modes in true
color, i.e., not with real palettes.

So if you changed the palette colors but didn't redraw an image, you'd
see no change, and palette animation wouldn't be possible.

Has anyone noticed this?
Thanks!

RE: Palm Pilot problem - any suggestions?

Have you tried re-installing the Palm Desktop software?  Maybe the problem
is in the driver.  Also, make sure that you have a good connection between
the cradle and the serial port.  Finally, do you have access to another
cradle?  That may help narrow down the problem.

I have a palm pilot that has mysteriously acquired a syncing problem.  (I

I eliminated the chance of it being a software syncing problem (testing it
on various machines) and I also eliminated the chance of it being a cradle
problem.

What is happening is when I press the hotsync button the cradle, the
"Connecting with the desktop using DirectSerial" pops up.  Normally what it
would do is the middle graphic would "animate".  However, now it just sits
there.  After about 1 minute, an error message pops up saying.

"The connection between your handheld computer and the desktop could not be
established.  Please check your setup and try again."

The Palm itself seems to work fine (Palm Vx) except it won't sync.  Has
anyone ever seen this?

Would anyone know if I did a certain type of "reset" or perhaps flash the

This is a known problem with debug ROMs, where any alert which winds 
up with one or more linefeeds at the end of the text message will 
trigger an invalid insertion point warning from the field code.

At 12:00am -0800 01-01-27, Palm Developer Forum digest wrote:
>No, but I can see *exactly* what is happening. The text field generated by

Actually the problem is that the alert code intentionally reduces the 
height of the text field bounding rectangle so that the trailing 
linefeeds are truncated. Unfortunately the insertion point was set to 
the end of the text when the field was created, and the insertion 
point visible flag was also set true, so the field code correctly 
complains about a situation where the insertion point should be 
visible but it isn't.

The only work-around currently is the one you suggest, which is to 
strip off trailing linefeeds yourself.

Why build an appliction?
I guess AvantGo would be enough. Set up a web page with forms
that can be filled out.

RE: Where ths Palm magazines?

Me too, but that essentially triples the production costs unless you 
do a low-end, newsletter-style publication. Above newspaper 
quality,below magazine quality. Do you care if it's good looking? (I 
know, that sounds like a stupid question. Personally, I'm only 
interested in the content.)

Re: Store binary data in a string resource

[Steve Achelis]

It looks like it is a problem in Constructor not saving the data (or I'm
misunderstanding something).

When I open my rsrc file, MyResourceString has ABCDEFG in it (something I
previously entered).  I backspace over these letters, click the View as Hex
button, and enter 0102030405060708.  I save, close, and reopen the file, and
MyResourceString is ABCDEFG!  This is very recreatable.

So now I create a NEW string resource, immediately choose View as Hex, again
enter 01..08, save and exit.  When I reopen it, this string resource is
empty!  I'm using Constructor 1.5b7.

If I enter the "string" in hex, unclick View as Hex, re-click View as Hex,
and then save, close, and reopen, the string usually updated.  There is
something very strange going on.  In fact, the string that was ABCDEFG
remains that, even if I enter hex while in View in Hex, toggle back and
forth, save, exit, etc.  It continues to be ABC...  Anyway, I can get binary
data out of the array, if I can get the array stored correctly.

New application architecture. Suggestions Anyone???

[Charles Martyn]

Hi. I have developed an application that manages marketing surveys. I have
built an IVR and a Web based response capture mechanism and now I want to
add that capability for a PALM device.

I have never built a PALM application before but I have been checking out
the O/S Docs and have downloaded Code Warrior trial and have been able to
create a few simple apps.

What I need now is a shove in the right direction. What I would like to do
is provide a PALM device to each member of our field survey team. The would
dial up an ISP and download the surveys into the palm device.. They would
then disconnect from the ISP and fill out the surveys. After filling out the
surveys they would then dial up the ISP and send the response data back to
one of our servers.

We are Using NT / SQL Server as a back end database. Our Web Servers are in
front of a proxy server and are running IIS. I am familiar with ASP
development.

What Books / Tools / Methodologies / Architecture should I use to build this
application?

Sincerely

Charles R. Martyn

Database Programming

[Nicolas Raitman]

Hi to all. I am having some problems when attempting to read some records
from a Database. The Database consists on:
Cliente (char *) NCliente (UInt16).
I have the following routine in order to read it but I have no luck in doing
it good. I will appreciate any help.

static DmOpenRef  AddressDB;
static LocalID  AddressDBID;
static UInt16   nRecords;
static UInt16   TableRows;
static TablePtr  pTable;
static UInt16  recordNum;
static Err   err;
static MemHandle mHandle;
static char   sz[120];
static UInt16  i;



AddressDBID = DmFindDatabase(0, "COMPOSICION");
AddressDB = DmOpenDatabase(0, AddressDBID, dmModeReadOnly);
nRecords = DmNumRecords(AddressDB);

  for (i = 0; i < nRecords; i++)
{


  mHandle = (MemHandle) DmGetRecord (AddressDB, i);

  if (mHandle)


   Cliente = (DatosCliente *) MemHandleLock (mHandle);
   StrPrintF(sz, "%s %d", Cliente->Nombre, Cliente->NCliente);
   FrmCustomAlert(CustomAlert, sz, "","");
  }

  MemHandleUnlock(mHandle);
  DmReleaseRecord(AddressDB, i, false);
}

DmCloseDatabase(AddressDB);

}

When I see the alert I can see perfectly well the Cliente->Cliente but not
Cliente->NCliente, what I am doing wrong?
Thanks,
Nicolas

What happens to old gadget data?

[Mitch Fawcett]

I'm playing around with gadgets and I have a question about the data that
can be stored with them.

Lets say I want to associate an integer with a gadget and I do something
like the following:

VoidHandvh;
FormPtr frm = FrmGetActiveForm();

vh = MemHandleNew (sizeof(UInt16));
if (vh)
{
* (UInt16 *) MemHandleLock (vh) = 1;
MemHandleUnlock (vh);
FrmSetGadgetData (frm, FrmGetObjectIndex (frm, MyGadgetID), vh);
}

What happens to the old data that was associated with the gadget (assuming I
had called the above at least once before)?

And... (somewhat of a C related question I think), if I have a second gadget
named MyGadgetID2, is it legal to follow the above code with this:

FrmSetGadgetData (frm, FrmGetObjectIndex (frm, MyGadgetID2), vh);

Sure you can!  I'm attaching an old post with good information.

What you need to do is launch the HotSync manager with either the
sysAppLaunchCmdSyncRequestLocal or sysAppLaunchCmdSyncRequestRemote command.
You can use SysAppLaunch or SysUIAppSwitch function to do it.

You can try this, but this function has not been tested.. it is something
that was written in this email and based on something written to launch
clipper.. (Please let me know if this works /grin):

Err StartLocalHotsync(UInt alertbox)
{
   Err err;
   DmSearchStateType searchState;
   UInt cardNo;
   LocalID dbID;

   // find hotsync and launch it
   err = DmGetNextDatabaseByTypeCreator (true, &searchState,
 sysFileTApplication,
 sysFileCSync, true,
 &cardNo, &dbID);
   if (err)
  FrmAlert(alertbox);
   else
  err = SysUIAppSwitch(cardNo, dbID, sysAppLaunchCmdSyncRequestLocal,
NULL);

 return err;
}

 (sysFileCSync is declared in SystemResources.h, by the way)

obviously protecting pre-release ROMs is necessary but i really can`t see
Palm`s logic in not releasing old ROMs to the public. afterall what possible
damage can it do.. has anyone ever heard of people using copilot to store
their addresses? its basically useless without the hardware. the same goes
for charging for 3.5 upgrades..

i`d really hate to see Palm turn into M$..

To see these error codes, you need to download the PalmOS SDK and look in
the header files NetMgr.h and INetMgr.h.  This really isn't a proxy error,
but an internal program error.
