PalmOS 3.5.* listboxes have no respect
Palmos 3.5.* listboxes don't seem to respect the hasScrollBar flag, or clipping regions. The end result: The listboxes draw the little scroll up/down indicators, (that don't work) when you have the hasScrollBar flag on. Worse still, the up/down indicators are draw all over the place, because they don't respect clipping regions. You can bybass the clipping region bug by writing your own LstDrawList(..) function, but (non-working) scroll up/down indicators are still drawn by during select events, through the call to FrmDispatchEvent(..) Is there any way to convince PalmOS not to draw scroll up/down indicators? -- For information on using the ACCESS Developer Forums, or to unsubscribe, please see http://www.access-company.com/developers/forums/
16-bit Colour & Prism/Future PalmOS
I've got a few questions about the 16 bit colour on the prism, and the future of PalmOS. Perhaps someone knows the answers? - On the new visor prism devices, what is the gain of using a Direct Colour bitmap? Is the only feature of using a direct colour bitmap the ability to specify a transparent colour index? - Suppose you specify a 16-bit colour bitmap, without using direct colour. Will the OS assume that you are using a 5:6:5 rgb bit distribution in all future PalmOSs?

Debugger for armlets ?
Hi all, We develop applications for Palm with prc-tools and we'd like to start making armlets. In prc-tools for windows, there is a arm-palmos-*.exe for almost every m68k-palmos-*.exe, but there is no arm-palmos-gdb.exe. Does that mean we can't debug armlets with gdb ? If not, is there other palm debuggers working with armlets ?

Problems with dmHdrAttrRecyclable.
Hi, I have some problems using the dmHdrAttrRecyclable database attribute. When I set that bit to the currently executing database, I get a Free Handle error on the Palm OS 5 simulator (or a crash on a device), after the execution of my database completed (exits from PilotMain). An interesting point is that if I switch to another application (with SysUIAppSwitch()) rather that just exiting normally, everything works fine and my database is deleted. I've seen many messages on this forum regarding this topic, some suggesting this way of using that attribute doesn't work http://www.escribe.com/computing/pcpqa/m48966.html http://www.escribe.com/computing/pcpqa/m63742.html while others assume it works http://www.escribe.com/computing/pcpqa/m74552.html Anyone could help on that ?

emulator/gremlins
Using emulator 3.5 Using gremlins, I've isolated an event which produces an undesirable effect in my program. How do you go about figuring out which event was run leading up to that point. I have a psf file saved a few events before the problem. I can't figure out what was pressed that leads to the problem. I read in the Palm Programming Developer's Guide that you can drop into the debugger. No idea how to do this. Using the step mode I can reproduce the problem consistantly. Potential bugs in emulator: When you press the step button it often runs several events. Incorrect event numbers. For example I told the emulator to stop at event 1000. The emulator then reads Event 1003 of 1000. Pressing the step button it then reades Event 1005 of 1004. Also what does the .pev file do. It comes up when I want to replay but I have no idea what is being replayed. Does it start at the beginning and run the whole gremlin sequence again.

Simulator (release) and frmUpdateForm problem
I have a situation where the release version of the Simulator fails to restore the screen behind a modal form, and does not send a frmUpdateForm event to the application, leaving the screen with some missing portions. The same application, when used with the debug version of the Simulator, receives the frmUpdateEvent and so the screen is redrawn properly. This occurs when using 16-bit color and 320 x 320 resolution. The Simulator is the dr12 version. Any ideas on how to solve this problem?

Null data question
Thanks Dave, The data type is UInt16. Sounds like I'll need to save a value that is a flag for no-entry. I'm guessing then that the big database programs do the same thing. When you query with statement such as IsNull then you are searching for this special flag (no data entered). Just don't know how the big programs know the difference then between the flag and an entered value. User could enter a zero or leave it blank which would then be coded as a zero. If I coded it as a Int16 then I could save the no-entry value as a negative value (which user cannot enter through my keypad) but hate to change a datatype based on this.Am I in the ballpark on this concept?

NULL data question
I have several numeric fields in a record. Some are required, some are not. If an unrequired field is left blank, shouldn't I write to the field as NULL? When I do, and then get the value from the databases after the save, the structure member indicates that the value is 0. I can always test for the value of zero so the display is left blank (NULL) but I'm not wanting the underlying data to be zero. Maybe there is no way to do this as the bits and bytes have to indicate something with zero being the lowest value. Curious.

DmComparF
Thanks Matt and Hal, It's a little clearer. It looked like Matt's example used a different prototype which was confusing at first.

I'm still not exactly sure what the sortinfo they want for each record with the SortRecordInfoPtr datatype within the DmComparF function.

DmComparF
Could I get a better explanation on the data type to
the record pointer. The DmComparF prototype says it's
a pointer to void.
The MemoPad example has a user-defined data type
(MemoDBRecordPtr). I'm also not sure what information
the SortRecordInfoPtr is expecting.
Looking at the API manual did not yield understandable
results for this programmer who has only been
programming on Palm for 5 months.
Here is the DmComparF I am attempting to write. Thanks
for taking pity on the lowly. Jay
Int8 sortLWRecords (void *r1, void *r2, Int16 other,

result = 0;
else if (r1->recId < r2->recId) //record 1 Id is less
than record 2 Id

cursor problems with fields!?
Has anyone noticed this behavior? You have several fields on your form. If you set the focus to one of the fields, with no text selected -press a button to change the text of the field -the focus remains -cursor continues to flash This is as it should be If you choose to have the text selected in the field and you change the text so the field is empty via a button, -press a button to change the text of the field empty. -the focus appears to be gone. It is not really gone but the flashing cursor that should be there is now gone. -cursor no longer flashes It doesn't seem to matter if you put statements in your code to set the focus to the field after the text change, the flashing cursor won't show up until you manual click the field.

general relational database question
This is a general question regarding a main database (table) and a related child database (table). If one were to create a relational database in a database program such as Access one would make sure that the information gathered from the main table was unique. I can create an auto incrementing value that would be saved in the main database and take that value and save it in each of the child database records thus creating a linking value. This is not a problem. But the other values within the main database (when evaluated as a unit) need to be unique (compound key). The only way I can conceptually visualize insuring a compound key is unique is by iterating through and checking all the values before a record is saved in the main database. Am I asking Palm to do more than it was intended or am I overlooking the obvious. In addition, when user switches from the main database to the child database one would prefer to see only those records related to the main database linking value of choice. In a database program such as Access one would just create a recordset from a query involving those linking values. Again, is this something I should stay away from or am I overlooking the obvious. If worse came to worse, I can always do some quality control after the data has been downloaded from the palm to a text file. Your insights are appreciated.

How to create a global variable?
Thanks to Brian and Paul. I got it to work. However I am curious how you knew this. The only reference to extern I find relates to libraries and that was in the Target Palm OS.pdf. I searched all the pdf documentation included with codewarrior and that was all there was. I put the extern Char *gJay in the header file and so didn't need to put it in each .c file. The string was just an example so I could go ahead and begin creating a database and remember the reference to the database after the function. If you are opening a database with the init function you would have to declare it global or it would lose scope after the function...but I don't see any examples of this being declared globally so was lost on how to do it. How did you guys know the extern keyword would do this. You don't need it in C or C++ to create a global variable.

How to create a global variable?
Creating a global variable: I tried to create a global variable and test to see the scope of that variable in a custom alert. So I created a variable called gJay. Char * gJay = "Jay"; When I put this code in the main.c file (the file that has the MainFormInit function in it) below the # includes above the functions right where it says Global Variables right below where the preferences were declared no compile errors When I put code in to read the value of that variable gJay in another .c file within the project (Information.c) Then I get a compile error. I get an undefined identifier error. It reads all other information from this file correctly. So I moved the declaration to the main header file. When I attempt to compile I get a Link error. LengthWeight.c Global object gJay was already declared in file Information.c Utility.c Global object gJay was already declared in file Information.c Main.c Global object gJay was already declared in file Information.c Utility.c Global object gJay was already declared in file Information.c About.c Global object gJay was already declared in file Information.c Information.c only attempts to use the variable. It is declared in the header and used in the Information.c file. I know the project is seeing the variable as I have my global variable colored light blue and when I type in gJay it turns light blue. Any help would be appreciated. Jay -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

StrAToI question
Thanks for the help. I realize that the textVar cannot exceed values that can't be held by a UInt16 var. It just seems kind of weird that you are setting the value of a UInt16var to a datatype that is a 32 bit. Not so much the value part but the fact that they are differing data types. Jay > Assuming that textVar is a positive integer > in string format, nothing. Well, a UInt32 can hold a wider range of integers than a UInt16, so you need to ensure that the string doesn't exceed the max value of UInt16.

StrAToI question
The StrAToI function returns an Int32. What do you do if the value to be converted is an UInt16? UInt16var = StrAToI(textVar); Thanks Jay -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
simple field question
all field handles hold text? Is that correct? Assuming that is true, and you want to take the contents of that field that holds a numeric value and put it in an integer database field, you get it as text from the handle-convert it to an integer using StrAToI so it can be written to the structure variable as an integer? Is this logic correct? Thanks for your help. Jay -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

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.

For instance, MIN(x, somefunction()) would be a bad idea - because if somefunction() is lower it would be called twice! And if you had min(x++, y++) then the smallest value would increase by two. If you want to avoid this then you can't use a macro... you'll need a function. -- 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/

Looking around inside PRC files - tools?
Hi all I'm looking for a tool that allows me to probe around inside a PRC file - the only thing I've managed to find so far is a program called PAR (http://www.djw.org/product/palm/par/index.html) which is a command line tool for manipulating PRC/PDB files. It works, but "list-extract to file-view with hex editor" is a rather tedious routine :) Does anyone know of any interactive tools for poking around inside PRC files?

Quciksort is actually quite dreadful at sorting a list that's almost in reverse order. So for a partially sorted list, quicksort is probably your best bet - except for the fact that quicksort is a recursive algorithm, which chews up your stack space rather quickly (which you don't have a lot of on the palm). > - insertion sort (I know very little abt this) > - bubble sort (the only sort that can stop prematurely when the list is > fully sorted, but slow!) There is never a good reason to use bubble sort. Avoid it like the plague! Most sorting algorithms will happily stop when the list is fully sorted; the only ones I can think of that don't are mergesort and heapsort. For a partially sorted list, I'd go with quicksort unless the list is large enough that stack space becomes an issue - then you might be best dropping back to something like insertion sort (which is basically just a less silly variant on bubble sort). To dependably sort a list which might be all over the place, then heapsort is a good bet on faster devices, however it always runs to completion which would be grossly inefficient on a slow processor like the palm's. If you list is not necessarily in almost-order, maybe take a look at *gulp* shell sort?

16-bit Colour & Prism/Future PalmOS
I've got a few questions about the 16 bit colour on the prism, and the future of PalmOS. Perhaps someone knows the answers? - On the new visor prism devices, what is the gain of using a Direct Colour bitmap? Is the only feature of using a direct colour bitmap the ability to specify a transparent colour index? - Suppose you specify a 16-bit colour bitmap, without using direct colour. Will the OS assume that you are using a 5:6:5 rgb bit distribution in all future PalmOSs?

PalmOS 3.5.* listboxes have no respect
Palmos 3.5.* listboxes don't seem to respect the hasScrollBar flag, or clipping regions. The end result: The listboxes draw the little scroll up/down indicators, (that don't work) when you have the hasScrollBar flag on. Worse still, the up/down indicators are draw all over the place, because they don't respect clipping regions. You can bybass the clipping region bug by writing your own LstDrawList(..) function, but (non-working) scroll up/down indicators are still drawn by during select events, through the call to FrmDispatchEvent(..) Is there any way to convince PalmOS not to draw scroll up/down indicators? -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/tech/support/forums/
