Experiences with POL (Palm Object Library)?

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/

Looks like I need to take defensive approach and do my exit form code on every unknown/known event except few safe ones like penUp/Down keyUp/Down etc, or are these unsafe too?

RE: Zire Rom ID problem
Devices without Flash ROM do not have serial numbers available in ROM.
Devices without Flash use a mask ROM that cannot be modified, thus cannot be
programmed with a serial number.
Treo devices may have a serial number, but do not respond to the
SysGetROMToken() call. You must use the
HsGetVersionString(hsVerStrSerialNo). Here's sample code:
char serialNumber[32];
serialNumber[0] = 0;
if (handspring)
{
UInt16 size;
size = sizeof(serialNumber);
HsGetVersionString(hsVerStrSerialNo,serialNumber,size);
}
else
{
UInt8 *p;
UInt16 size;
if (SysGetROMToken(0,sysROMTokenSnum,p,size) == 0 size
0 *p != 0xFF)
{
if (size sizeof(serialNumber)-1)
size = sizeof(serialNumber)-1;
MemMove(serialNumber,p,size);
serialNumber[size] = 0;
}
}

When I was at PalmSource, we did talk about POL a bit. However, Palm OS Cobalt has its own C++ layer underneath the Protein API, so the thinking was that once the tools stabilized and there was a standard C++ ABI, those objects would be directly exposed. There was some talk about getting POL ported to Protein, but we never started business discussions about this. I expect with the move to Palm OS for Linux, the C++ API discussion will be opened up again within PalmSource, but I don't know if anything will be exposed to developers. Somehow I am hesitating, I am embarrassed to add an additional layer to my software: Is it my bug or is it in the layer, which documentation do I have to consult (POL, Palm), ...? I really like programming with POL, and I'd probably not do a complicated program for Garnet without it right now.

re: I need help testing something on a T5
Instead of sending out your whole application and having people bother obtaining demo licenses, why don't you simply create a separate stand-alone application that does nothing but test the function you have a problem with? It probably won't even have to scan for viruses - just enumerate every file on every memory card, open each one of them and read its contents, then close it. In fact, this apporach (trying to isolate the minimal code that illustrates the problem) can often help you find the problem yourself.

The error I am getting is sysErrNoFreeResource. 960x720 at depth 16 will require about 1.4 MB of contiguous space available in the dynamic heap. The first question to ask is whether you are on a device that ever has that much space in its heap. Some devices do, and some don't. Even if a device does, it may not be contiguous by the time your program runs and allocates and deallocates a bunch of stuff. A good test is whether you can do a MemGluePtrNew (960 * 720 * 2). If so, then you have *some* hope of being able to create the bitmap. If not, then you're definitely out of luck. The next step is probably to use the BitmapRsrc example code from the developer knowledge base to create the bitmap. I don't know what the built-in functions use to allocate memory (they may just use regular MemPtrNew() on some or all devices, in which case the maximum size will be 64kB), but I do know that the BitmapRsrc functions use some sort of trick that lets them allocate more than 64kB. Whatever you do, make sure you have good error handling. :-) - Logan -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Text Column not displaying on the last row
I'm a novice Palm developer, so I'm very confused.
I have a loop that will display information in a table. It works fine except
for the last row. On that row, the only text field remains blank.
I've used the emulator and debug to step thru the code. It executes the same
code for each row.
===
static Err SessionDetailLoadItem(void * table, Int16 row, UInt16 column
, Boolean
editable, MemHandle *dataH
, UInt16 *
dataOffset, UInt16 * dataSize
, FieldPtr fld)
{
UInt16 recordNum;
MemHandle recordH;
ptrGNSCsessionDetailsessionDetailRec;
MemHandle tmpStringH;
char*tmpString;
UInt16 tmpColumn = column;
// Get the record number that corresponds to the table item.
// The record number is stored as the row id.
recordNum = TblGetRowID (table, row);
recordH = DmQueryRecord( g_gnscDetailDB, recordNum);
//ErrFatalDisplayIf ((! recordH), Record not found);
if (! recordH)
{ // no records
tmpColumn = noRecordSelected;
}
else
{ // lock the memory handle
sessionDetailRec = (ptrGNSCsessionDetail) MemHandleLock
(recordH);
}
tmpStringH = MemHandleNew(MAX_STRING_SIZE);
switch (tmpColumn)
{
case noRecordSelected:
tmpString = MemHandleLock(tmpStringH);
StrCopy(tmpString,No Records);
*dataH = tmpStringH;
*dataOffset = 0;
*dataSize = MemHandleSize(tmpStringH) ; // add 1 for
null terminator
break;
case SessionDetailUPCCol:
tmpString = MemHandleLock(tmpStringH);
StrCopy(tmpString,sessionDetailRec-upc);
*dataH = tmpStringH;
*dataOffset = 0;
*dataSize = MemHandleSize(tmpStringH) ; // add 1 for
null terminator
break;
case SessionDetailLineNumberCol:
tmpString = MemHandleLock(tmpStringH);
StrIToA(tmpString, recordNum);
*dataH = tmpStringH;
*dataOffset = 0;
*dataSize = MemHandleSize(tmpStringH) ; // add 1 for
null terminator
break;
}
MemHandleUnlock(tmpStringH);
//MemHandleFree(recordH);
if (tmpColumn != noRecordSelected)
{
DmReleaseRecord(g_gnscDetailDB, recordNum, false);
MemHandleUnlock (recordH);
}
return (0);
#ifdef GNUC
CALLBACK_EPILOGUE
#endif
}
==
But the last row doesn't have the value. When I examine the contents of
tmpString, it has the proper value.
Now here is the funny part. If I tap the column in the field above it, then
tap back into the last row twice (not a double tap), the value appears. When I
tap back in the column on the line above, it disappears again.
Can someone explain what is going on?
Thanks

re: giving error as app1 just read from memory location 0*000000001,which is in low memory
What I suggest, if you're using the Palm OS Development Suite (PODS) is to run your program under the debugger, and let it give the error message. You will then be given the opportunity to go into the debugger. From there, hopefully a call stack will be displayed, showing exactly where in your code was executing at the time of failure. There may be calls to system routines made by other system routines, but check the calls that you make for proper parameters. For example, is there an uninitialized or null pointer somewhere? That said, I've noticed things like this happen during normal operation of my Handspring ROM. It could be normal OS functioning, if nothing else seems wrong. The way to determine this is to try your same application under (say) the Garnet (5.2) simulator, and see if the same issue happens. If there is no more complaint, then perhaps it was normal operation for your older version of OS. -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Just say
int my_ascii_value = 'A'.
Single characters already have an integer type in the C language.

Re: PalmOS asc() equivalent?
Just put the hotsync name in a Char* my_string and step through it. the
value of *my_string will be the value that the pointer points to, which
would be the ascii value of the current char in the string. something like
this would work...
Char* temp = my_string;
for(i=0,iStrLen(my_string);i++){
assci_value = *my_string;
//do something with the ascii value here//
my_string++;
}
my_string = temp;

Hi, all...I'm having problems finding an asc() equivalent in the API.
What I need is the ASCII value of an given character. So:
int my_ascii_value = asc('A');
printf(Result: %d, my_ascii_value);
Result: 65
Is there a way to do that with the PalmOS API? I don't see a function or
API to do that. Any help would be appreciated.

Re: giving error as app1 just read from memory location 0*000000001,which is in low memory
From: rupesh kumar [EMAIL PROTECTED] i am trying to access the contacts database.my application name is app1. its compiled well but at runtime when tring to get the data it is giving error as app1 just read from memory location 0*1,which is in low memory. why this error is coming ? In general this means that you're passing a null pointer to an API call, or using a null pointer as a structure reference. The only strange thing is that the value reported is often the offset of the value requested from the start of the struct which should really be an even number because of structure padding. Anyway. The first thing you need to determine is where in your program this is happening, either by debugging or by writing to a log as your program operates. Without this information it is very difficult to identify which value is incorrect. You could also work carefully through your code making sure that every pointer is tested for null. This is time-consuming but is useful to ensure that your code is robust.

Re: PalmOS asc() equivalent?
Chris Williams wrote: asc() is to get the ASCII value of a character. I need to use it to get an integer value from the Hotsync ID, that I can work with to get a serial number. It's fairly difficult to make a serial number without touching numbers at all. As others have already said, in C characters *are* numbers. A char is an integer type, just like short, int, or long. One additional word of warning: in C, characters can be signed or unsigned integers, just like the other integer types. This means if you deal with characters greater than 127, you may have to take some care to ensure they don't come out as negative numbers. For example, if you have a character that's ASCII 130, you might end up getting -126 if you do the naive thing: char c = '\202';/* octal escape code for character #130 */ int i = c; printf (%d\n, i); If you want all positive numbers, the easiest thing to do is to typecast your character to an unsigned char before converting it to another larger integer type that can handle positive numbers larger than 128: char c = '\202'; int i = (unsigned char) c; printf (%d\n, i); That will print 130, unlike the first example, which will print -126[1]. - Logan [1] Provided of course that you're on a platform that implements printf(). Palm OS doesn't, but I'm just talking about the C language in general here. -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Fatal Alert??? is this palm pilot ruined?
So i've been using this new palm pilot (i actually forget the model) but it was using Palm OS 5. and I've been syncing it with no problems. I then got rid of the Palm pilot, but got my hands on an older Palm Vx. I think it uses palm OS 3 or something. I then decided that I wanted all of the backedup info from the previous palm pilot to be transfered to this older Vx, so I just synced it with the computer thinking everything would be fine. It started syncing fine, and it was just taking awhile because it was the first sync (i assumed). When i went back a few minutes later to check on it... there was a Fatal Alert dialogue box that said... Fatal Exception, with only a reset button. Resetting works, but it goes right back into the Fatal Alert box. I can't even turn the palm pilot off now. I did a hard reset, same alert. I tried resyncing, same thing. I drained the battery for a few days, and charged it up again, same thing. It just won't get off this Fatal Alert box. ANY IDEAS this is killing me!! Thanks!

Re: T650 resource cloning problem
the only attrs that i'm using are: resourcedb and backup bits.
