Re: memory leaks vs. unallocated chunks
Thank you very much for your response. Unfortunately I'm still stuck. Actually, the problem is more that ClearPickedList doens't work correctly once I do free the memory. I'm pretty sure about where the memory leaks are coming from, but fixing them breaks ClearPickedList (and only on the last call). As for putting ClearPickedList in AppStop, I have it in the exit cleanup routine for this form, since that would take care of the memory held by the form's list. Once the form has been dismissed, that list no longer exists, so it'd never tie up any more memory than what it had upon dismissal of the form. So any cleanup for this list actually has to go in the cleanup for the form and isn't really helpful in AppStop. My problem is mainly that I add a picked item and call fill list which first calls clear list. This works repeatedly, but then once I try to exit the form, and run ClearList without first adding a new item ClearList doesn't work. ie: AddPickedItem Clear List Fill List AddPickedItem Clear List Fill List AddPickedItem Clear List Fill List ClearList (this call doesn't work, memory has been deallocated) The obvious difference between this call to Clear List and the working ones is that they all have a preceding AddPickedItem, but I just can't see where, in AddPickedItem, the code is that makes ClearList work. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Re: T/2 Voice Memo button
I've never seen any documentation about how to use the "Voice Memo" button, but it behaves like another hard key. While the hard keys produce key events 0x0204, 0x0205, 0x0206, and 0x0207, the "Voice Memo" key produces 0x0214. The "Voice Memo" key only appears in conjunction with the 5-way navigator, so perhaps that would be an adequate test.

While I agree with Brad that form C might be still loaded or loaded and unloaded quickly I also found a third alternative - - that some form sequences could lead to a form image of a closed form hanging around. I never really pinned down what I was doing wrong, and eventually removed the save behind flag on all forms and handled all painting myself, although that's more because we were supporting animation effects than anything else. My memory of the problem was that it seemed to be related to raising a form with save behind set, then covering it with a form that didn't have save behind set (or vice-versa). Although everything functioned properly a form image seemed to be retained and would sometimes be used as a 'blank slate' onto which current form controls were drawn.

Database help.
The way I am currently using the palm database does not seem correct.
Yes I have gotten it to work, and it is doing what I ask it to do, however,
It seems WAY too complex and there has to be a better way.
Currently I keep my information in a struct Rec
For example:
Struct Rec {
char* data;
int foo;
char* bar;
... constructor destructor etc...
};
When I write to the record I am writing Rec.data, which is a char star with
each field seperated by "~"'s.
For example if foo is 5 and bar is "asdf" then data would be "5~asdf"
When I pull the data out of the DB I put it into a new rec's data field.
I then have two functions, CombineDataIntoFields and ExpandData. This fills
the appropriate fields, foo and bar, with the data out of data, or vice
versa, creates data by concating all the fields with the "~" spacer.
Like I said, WAY too complex.
I have tried just writing a pointer to a record this way:
Struct Rec {
int foo;
char* bar;
};
// rec is a *Rec
newRec = DmResizeRecord(db, index, sizeof(rec));
errDb = DmWrite(MemHandleLock(newRec), index, rec, sizeof(rec));
I know there has to be a way to do something like this but it isn't quite
working yet.
Any suggestions?
tia,
Steve K

bus error when table custom draw routine is modularized
I've got a custom drawing routine for an item in a table that need to draw
quite a bit of stuff, so I thought I'd modularize the code into some
different drawing functions. In the process, some calls to the following
conversion function were moved from the table callback out to the drawing
functions. This function didn't cause problems when it was called from
inside the callback routine, but if it's called from the drawing functions I
get a bus error when the calling function returns control to the table
callback routine.
static Char * SecondsToString(Char *strTime, UInt32 seconds)
{
UInt8 hours, minutes;
minutes = seconds / 60;
// round up
if (seconds % 60 >= 30) {
minutes++;
}
hours = minutes / 60;
minutes = minutes % 60;
TimeToAscii(hours, minutes, tfColon24h, strTime);
return strTime;
}
For example, if my table callback function contains this I'm OK:
static void MainFormDrawRecord(MemPtr table, Int16 row, Int16 column,
RectangleType *bounds)
{
...
Char strTime[6];
UInt32 aNumber = 10;
...
SecondsToString(strTime, aNumber);
// Drawing stuff here
}
But if I do this, I get the error:
static void MainFormDrawRecord(MemPtr table, Int16 row, Int16 column,
RectangleType *bounds)
{
...
UInt32 aNumber = 10;
...
DrawNumber(aNumber);

}
static void DrawNumber(UInt32 aNumber)
{
Char strTime[6];
SecondsToString(strTime, aNumber);
// Drawing stuff here

Free Handle
After belatedly moving to system 5 testing I'm getting a "free Handle" error in system code between events (needless to say, the problem doesn't occur in system 4 testing). I'm using CodeWarrior 7 with the Palm OS 5 SDK (68K) R2 on Window 2000 (5.00.2195) Although I don't doubt that my code is to blame, several things are making this difficult to debug: The usual behavior is for the simulator to hang. It may be trying to give me a message (when I kill it with Task Manager I'm sometimes told it is waiting for a response from me). It does log a free Handle message in the Error Log file. If I step through the code the hang occurs after a FrmGotoForm call. Breakpoints set in PilotMain or anywhere reasonable in my code don't get hit. I did manage to come up with a test case that actually gives an error message rather than hanging but if I switch to the debugger, the stack traceback doesn't include any of my code. The PilotMain at the top isn't mine. The error message in the simulator (as in the error log file) is memorymgr.c line 3583 Free Handle and the traceback is __Startup__ PilotMain ProcessNotify LaunchDBHandleSetInfo LaunchDBHandleSetInfo PrvUpdateLaunchDBEntry What I'm doing just before the FrmGotoForm call is copying a database with some changes. Attempts to pinpoint the cause by leaving out various things (and the above trace) suggested the problem had to do with the AppInfo block. Leaving out the update of the AppInfo block did eliminate the failure in that test, but it reappeared later (in about the same place in my code -- updating a database but without updating the appinfo block) in its more usual form (i.e., just a hang). Further investigation suggests the connection with the appinfo block may be spurious, but... Any suggestions? I suppose updating my copy of CodeWarrior might be a good one. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Both versions should be OK. Yours has the
benefit of not eating up precious stack space;
his has the benefit of being safer (you don't
have to worry about the allocation failing, or of
the object being leaked by exiting the function
before calling delete).
Your coworker's explanation as to why your
approach is wrong seems bogus to me. I'm not
sure what he's getting at with his comments about
"system memory" or "unallocated space".
However, your use of references here is
definitely non-standard, and I'm not even 100%
sure that it's correct. For instance, what if
operator new() returns NULL? What does Data
refer to? What does &Data resolve to? I know
what happens with the compilers I use from
personal experience, but I'm not sure that the
C++ spec says. Personally, I'd use the following:
void TPrinterUtil::ReadConfiguration()
{
TPrinterData* Data = new TPrinterData(*dbName);
// do something with Data
delete Data;
}
or, better yet:
void TPrinterUtil::ReadConfiguration()
{
auto_ptr Data = new TPrinterData(*dbName);
// do something with Data.get()
// Data need not be explicitly destroyed

Writing it this way is better from a maintenance point of view but
consumes stack space. In this case it probably does not matter, but in
the case of the following
unsigned char buffer[ 2048 ]; // 2048 bytes on the stack.
vs.
unsigned char *buffer = new unsigned char[ 2048 ]; // 2048 bytes from
the heap and 4 bytes from the stack.
it makes a very big difference.

Extra ctlRepeatEvent from repeating buttons?
Has anyone else seen a repeating button give an extra ctlRepeatEvent when it's released? If I hold it button down, it works as it should, but I always get an extra event when I release it. This can be replicated with a quick tap on the button. All I'm really doing to handle those events is calling the function that handles the same thing in response to the hardware up/down buttons, and returning false to keep the repeating button working. This is basically what I've seen in the docs and all sample code so far, so I can't tell if there's anything I'm missing. I would use scroll bars, but this is a form with multiple "views" (done by hiding and showing different controls), and the scrollable fields are different sizes in each. I haven't yet been able to get hiding and showing of scroll bars working cleanly.

have logging in a release build or leave it out. So the control is
independant of release or debug.

Hard buttons and alert
Hi, How to disable hard buttons for the time when alerts are poped up? The buttons are reprogrammed in my application. However, as an alert resource gets called the hard buttons original assignments are restored for that time. The hard buttons interception implemented for an active form appears to be cancelled by any alert call. I would be happy just to disable the butons for an alert call time. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

sliders
Hello , I am using a slider in my control with value from 0 to 12 and a default of 3 . But I am not able to indicate to the user the current value of the thumb of the slider as the markings on the slider are not changing as per the size of the slider . Is there a way to change the default markings of the slider background so that I can show only 13 markings from 0 to 12 without changing the width of the slider ? The slider has to fit in the small size along with other controls . Please help . Thanks & regards , Dhanashri . _ Is India taking over the US?

memory leaks vs. unallocated chunks
Hello,
I am having a problem that I have spent days trying to figure out with no
success. My program includes a form with two lists, the options list and
the picked list. The options list is filled when the form loads and by
selecting items from the options list and clicking a button, the user can
fill their personal "picked list."
There is something slightly wrong with my function for adding to the picked
list however. If I use the function as is (shown below) I end up with a
number of memory leaks equivalent to the number of list items added after
the first item. (so I know that the leak is within the code in the
outermost Else clause of AddPickedItem). I thought that the problem was
that I was setting the list pointer equal to the pointer for a newly created
string, but never dealloating the memory that was held by the previous
version of the list. So I added a line (now commented) to free that memory.
However, when I add that line, my function ClearPickedList no longer works
upon closing the form. (It does however work when called at the beginning
of FillList each time a new item is added to the picked list.) I can an
unallocated chunk error. Any Ideas on this? My code is all below.
on a side note, when there are memory leaks, the emulator alerts me and
tells me that details can be found in "the log file." What log file?
thank you!

Re: Faking relational databases with PDBs
On Wed, 20 Aug 2003 08:43:42 -0700, "Jeff Ishaq" <[EMAIL PROTECTED]> wrote: >I am curious about your implementation. If a record in DB1 >refers to a record in DB2, what constitutes your primary key in this >relationship? In other words, if not the Unique ID, what do you store >as the 'index' of the referred-to record in DB1? Well... indeed there's a requirement that the records in DB2 have to be sorted by a unique key. That might not always be true, for instance, if you are storing patients sorted by their names, then you can't do a binary sort to find a patient (the name might not be unique, so you need something like a patient number, and you don't know what order they will be in). In that case the method I described wouldn't work. But suppose DB2 contains test results; each test result is assigned a date and a number in the day: the test records are sorted by date and day number. So database DB2 looks like: dateday number test data 01/01/2003 1 data 01/01/2003 2 data 02/01/2003 1 data 02/01/2003 2 data If you need to sort on another key, then in DB1 each record contains the sort key, date and day number. The date and day number allow you to call DmFindSortPosition and find your test result in DB2. In the case I first mentioned, where the binary search doesn't work, then I guess I would have to use your method; I'm a little bit worried about two things though: 1) performance on a big database :we routinely have databases with something like 1 records. When I have some time (which should be pretty soon, maybe in 2015) I'll try to benchmark that. 2) I don't trust that "unique" id ; there have been discussions in the past here and the conclusion seemed to be that it's unique most of the time, and that there's very little chance that it might be duplicated, the probability is low, blah blah blah, and that disturbs me because I am an obsessional paranoid who should seek professional help (but right now I'm busy writing software). I don't remember exactly, but the issue was not only wrapping but it had to do with seeds and synchronization and stuff like that. You can search for it on this forum though. Thus my feeling right now is that I would do everything I can to continue using the binary search method, even if it means reorganizing the data. For example, patients could be sorted not by name but by a patient number. There could be an index database on the side where the patients would be sorted by name. Then, the patient number would allow you to find the patient record by doing a binary search on the patient number. This would allow me to have other index databases to sort on other info. I might change my mind after benchmarking though What's that OS6 database stuff you keep mentioning? I read things on OS6 but saw nothing about that... Got a link?

new/delete problem in PALM OS

How to get the default Icon database?
Hi all, Sorry my poor english. I know the "Icon Manager" can set the icon database(like DateBk5 icon database) as the default database, but I don't know how to get the default icon database, because all of icon database has the same type :'Rsrc', I tried to search some api functions to do it, but I can't found anything. Can anybody give me some ideas to implement get the default icon database? Thanks!
