My program uses a table which is divided in 3 columns : date, operator and
value.
All the columns have customTableItem style.

Yes, I have and nothing strange.

Such memory is not allocated from the heap and won't cause memory leaks. 
Static variables equivalent to globals with a restricted scope; it doesn't make
sense to free them yourself.

It can't be that easy, besides, I have tried a couple things, i.e.

wrong. Adding the 4th BITMAP line in the RCP file:
BITMAPFAMILYEX ID ULHome

BITMAP "ULHome24bppD2.bmp" BPP 16 DENSITY 2 //<<--- Doesn't like
this!

disappears completely or throws me into MS's C++ debugger! (I hate it

I must be doing something out of sequence, so what procedure would you

OK, Chris, if you are right, then what happens with

SysNotifyUnregister (cardNo, dbID,...)

Could this fail if the dbID of your application changed during

2) In the Hotsync program on the emulator: Menu->Modem Sync
Preferences->Network
3) In the Hotsync program on the emulator: Menu->Primary PC Setup enter your
computer name, and enter 127.0.0.1 in the primary pc address.
4) In the Hotsync program on the emulator: Select service->Enter phone

Multi segment shared library with PRCTools

[Magnus Berg]

In my project, the GUI application was converted into a multi segment 
app a few months ago. Now, the shared library part needs the same 
operation but when I try to do the same thing with the library, the 
linker complains about not finding:

GccLoadCodeAndRelocateData

and one other that does the opposite.

I'm guessing these functions are included in the startup files which I 
don't include since I link with the -nostartfiles switch. So the 
question is, how do I find these functions without including the startup 
files?

stubgen and multigen are reasonably well documented by themselves but 
I'm unable to find any docs on how to combine the two.

I found some info about making a glib shared library instead of a system 
shared library, is that the way to go?

Anybody?

BlueTooth error codes

Hello

Anybody knows where to find BlueTooth error codes? All I know there is
blthErrorClass defined but I can't find corresponding codes. CW dialog
"Search for Palm OS Error COdes" does not help either.

What I want is to inteligently handle selected error codes from ExgPut().
For example pressing cancel returns 0x3127 - this might denote user abort
and the user should not be bordered with a nasty error message "Error

It's not the call to TblSetCustomDrawProcedure (with 3 parameters) 
that's the problem here but the third parameter of that call which is a

 void ()(void *, short, short, struct RectangleType *)

Got it? Your definition of MainListDrawFunction is the problem! The 
second and third parameter of MainListDrawFunction must be unsigned 
short instead of short as it currently is in your code!

Secondly, I tried casting these parameters to (UInt) with no luck...

I didn't realize out last developer was using C++ whcih I'm not all that
familiar with,
is this a C++ issue as well? This'll take care of 4 out of 6 errors if I
can figure
this out, so hopefully I can squeeze by the C++ barrier on this.

If you are referring to that abominable example in the article
then the answer ia absolutely not. The author was on drugs.
He/She didn't have a clue how to manage memory or Dynamic lists.

If done correctly, the list is allocated/freed with one MemPtrNew/Free 
call.

One locked block per list? Sheesh. But still I must ask "Why?".

Locked-Schmocked...Locked memory is nothing. The principle
purpose of Handles is to permit reorganization of DB memory 
into contiguous extents for sequential access. For purposes
of lifetime program allocations, it is inconsequential.

Less likely than what? I've never run out. That would be 'Less likely than Zero'.
Code space OTOH, is in desperately short supply.

Why is that? If you're talking about "to the byte" your life must be
hard. Knowing requirements to the nearest 10K is good enough
and quite easy to estimate.

There's not? What are you doing with it? Burning it up with
C++? If that's the case, then we're on different pages.

Yes I am. Deallocating is:

if(pListTxt != NULL)//pretty hard
   memPtrFree(pListText);   //huh?

and there are at most two of those clauses for a dynamic list.
Since one of those is in the builder method, it is never repeated
for additional lists. Additional lists get one clause in the 
stop program method.

I didn't find it.
The solution was provided by the engineers that developed the API.
They even provided support methods to make the job easy.
The API is one of the most efficient and finely crafted in the world.
If you use it well, as intended, very small programs do very large
things.

All I do is make use of it, as opposed to replacing it.

You have to call FrmDrawForm to get the label redrawn.  Or you could try

is a bit unstable, so why not just use WinDrawChars("Hello",5,30,30) to do

newbie question: how to read a string from a MemHandle?

hi everbody, i am new to palm and its memoryhandles.

I receive a string and have to store it in a MemHandle, because i resize it
in a loop while receiving the data. However, i´ve got no idea how to read
the data from the handle, neither a normal (char*) cast, nor a sprintf
works. I´m sure it is pretty easy but i don´t know how to do it :o|

Re: Re[2]: DB create/write problem

[Thomas Damme]

Hello Boris,

this is more fundamental:

1) It seems, you dont understand the meaning of sizeof(). This function is
processed at compile-time and just inserts the length of a specific
data-type. That means:
sizeof(UInt8) == 1
sizeof(UInt16) == 2
sizeof(Char) == 1
sizeof(Char*) == 4 (its a pointer and all pointers are 32 bit)

what about your struct? : struct Airline
sizeof(Airline) == 6 since its a UInt16 and a Char*

the sizeof-function only works for datatypes not for memory-chunks.

2) when you assign a new chunk of memory to airlineName, it resides
somewhere in memory but not at the address of air.airlineName.

Thats why you have to create the new record like this:
ulLen=sizeof(air.airlineID)+StrLen(air.airlineName)+1;
h = DmNewRecord(gDB, &index, ulLen);

and write it to the record like this

// The ID; here sizeof() works
err = DmWrite(p, 0, &(air.airlineID), sizeof(air.airlineID));
// The Name; here it does not.
err = DmWrite(p, sizeof(air.airlineID), air.airlineName,
StrLen(air.airlineName)+1);

Hope this helps,

Thomas

Re: DmAttachRecord with MemHandleNew

[José dos Santos Machado]

Todd Niec escreveu:
Is it possible to use DmAttachRecord with memory that was allocated with
MemHandleNew()?  The documentation doesn't say you can't, but it seems
like I get weird behavior if I try this.
Short answer: No, you can't. Use DmNewHandle instead.

Re: Codewarrio stack usage with temporaries

AHA.  the temporaries in question are all being passed to a function...

Are there dissadvantages to using that pragma?  speed might be one.  Is
the speed difference signficant?
speed will be slightly slower, but it's not significant; I don't remember 
why we didn't make that always on for Palm OS.

If there are dissadvantages, Can I turn that pragma on in one section of
the code and then off again afterwards?
You can control it function-by-function, but not within a function.

Re: newbie question: how to read a string from a MemHandle?

[Gearoid Murphy]

I'm not sure what you are doing wrong.  As I see it to write the data to the 
handle you should be doing something like the following:

// global MemHandle
MemHandle h = NULL;
// Append data to whatever is already in handle
void WriteDataToHandle(Char *dataInP)
{
   Char *strP;
   Err err;
   UInt16 len = StrLen(dataInP);
   if (!h)
   {
h = MemHandleNew(len+1);
if (h)
{
 strP = (Char *)MemHandleLock(h);
 if (strP)
 {
   StrCopy(strP, dataInP);
   MemHandleUnlock(h);
 }
}
   }
   else
   {
 err = MemHandleResize(MemHandleSize(h)+(len+1));
 if (!err)
 {
  strP = (Char *)MemHandleLock(h);
  if (strP)
  {
// Append data
StrCat(strP, dataInP);
MemHandleUnlock(h);
  }
 }
   }
}
// Read data from handle
void ReadDataFromHandle()
{
Char *strP = NULL;
if (h)
{
  strP = (Char *)MemHandleLock(h);
  if (strP)
  {
DisplayStr(strP);
MemHandleUnlock(h);
  }
}
}
// Finally free handle
MemHandleFree(h);

at first thanx for your reply. However, when i try to access strP my
programm crashes telling me it read memory from the memory manager data

unlocked it, locked it again by
strP = (Char *)MemHandleLock(h);

Setting WinDrawTruncChar issue

[Régis Daniel de Oliveira]

Hy all!


I use the folowing code to set color of the text that i will draw on a list
to blue:


RGBColorType rgb;
MemSet(&rgb, sizeof(rgb), 0);
rgb.b= 255;

WinSetTextColor (WinRGBToIndex(&rgb));

WinDrawTruncChars(Descricao, StrLen(Descricao), bounds->topLeft.x,
bounds->topLeft.y, 150);

But, when I set the focus on this text, the color continues blue, and not
changes to white.

How can i set the color of the text when it is selected?


Thanks!

 DmReleaseRecord(PedidosDB, NuevoIndice, true); // right?

 IngresaItem(item.items);   //Load from fields to

Re: Recomnd 16-Bit editor/converter?

[Ben Combee]

there lies another issue, which, would definately be something for
ben combee (metrowerks) to look into, and, handle more correctly
on their side. the resource output is a whopping 84096 bytes.
yes, thats > 65505 (max limit set allowed for a resource). most
likely, rez is barfing within codewarrior because it cannot handle
the large resource.
Ah... you hit a bug in the V9 linker where it would crash if an input PRC 
file (or PilRC RO file) had a resource that was too larget.  This is fixed 
in 9.2 -- the linker doesn't crash, but instead warns you that your 
resource is larger than supported by HotSync.  The CW debugger supports 
downloading these "larger than 64K" resources, but you can't get them on to 
a device by normal means (HotSync, beaming, VFS).

BTW, 65505 isn't the limit anymore... the OS 5 devices actually have a 
slightly lower limit due to the larger size of the internal data 
structures.  I don't know the exact number, so I'm warning for 64000 bytes 
or more in a single resource to be safe.

Re: nilEvent problem

[Alan Ingleby]

Perhaps you should be checking how long it's been since your last "time bar
drop", an don't do it again if it's been less than 250ms.

You should also look into UserEvents, and generate them where needed, rather
than relying on nilEvents, as these can be generated when you don't expect
them.  nilEvents are generated by the system to flash the cursor on and off
for example.

It could.  .lib files are compatible between the two linkers, but you may 
need to fix your target settings in the 68K Target panel, since that 
wouldn't have transferred over from the Palm OS 68K panel.  Maybe your

Re: Any tool for multi-platform?

[wterreblanche]

You did not really specify what language you prefer to program in.  I 
think this should be you first priority.  For example... if your 
applications will rely heavily on graphics and speed, then I 
recommend you consider a C compiler like GCC (open source) or 
CodeWarrior (commercial).   But if you prefer something similiar to 
the Visual Basic environment, I recommend NSBasic.  These compliers 
have versions available for Palm and for WinCE.

But be warned... the PPC and Palm are quite different machines and 
whatever tool you choose... you will probably still have to write two 
versions of the same program.  There are some highly experienced 
programmers that manage to write their code in such a way that they 
can compile it for both platforms, but this is not easy to achieve 
and require in-depth knowledge from the programmer of both 
platforms.  

There are of course many other solutions that you can consider if you 
do not specifically require a low level compiler.  But such solutions 
might be good for in-house corporate solutions, but not so good if 
you wanted to create a commercial program.  It all depends on what 
type of program you really want to create.

Again, I have a doubt. Sorry for this Dave. But I am not gettin why 
would the hotsynch protocol needs to be restricted to handle a data 
of 64K _only_ ?I mean, why not 32K or 128K or whatever? Is it just an

Which device?  This works for Palm OS 4.1 and less, but might not work for

Yes.  Your fldAttr variable should be of FieldAttrType, not a pointer to 
it.  Then, you would pass in &fldAttr, to take its address.

Re: TblSetCustomDrawProcedure() - illegal implicit conversion

[Ben Combee]

I don't quite understand what you mean by "adjust the actual type of the

The return type of MainListDrawFunction is void, and the 2nd and 3rd
parameters are of type "Word" being "UInt16".
I tried casting the everything to UInt16, as well as changing "Word" to
"UInt16" with the same results
I just noticed that I got it backwards.  It was an UInt16/Word, but now the 
type is just Int16.

Re: Codewarrio stack usage with temporaries

How does code warrior handle stack usage for unamed temporary variables?
I have a procedure that creates lots of unnamed temporary variables as a

the
function executes, but the stack usage steadily increases and increases
as the function executes.  Eventually I run out of stack space.
CW allocates all temporaries on the stack at function entry time.  However, 
there is a case where your stack usage can increase while your function is 
running -- the compiler defaults to deferring cleanup of the stack used for 
argument passing.  If you've got a loop with a function call, using

#pragma stack_cleanup on

will cause the compiler to remove items from the stack as soon as a 
function returns.

That's just confusing the issue isn't it? :-)

There is not a command line in the PalmOS in the sense that there is in

Try it and see.  My suspicion is that is will probably fail, as DmWrite is
designed to stop you from writing to the wrong place etc, but you never
know...

Why can't you just keep track of the type of memory yourself, then use the
appropriate DmWrite or MemMove calls? Even if DmWrite happens to work, it is
always going to be slower than MemMove...

RE: Coding Standards

[Keith Rollin]

That's close to mine.  Personally, I'd have it as:

void MyFunc(Char* buffer, UInt32 type)
{
switch(type)
{
case 1:// This is an example with braces.
{
StrCopy(buffer, "One");
break;
}

case 2:// This is an example without braces.
StrCopy(buffer, "Two");
break;

default:
StrCopy(buffer, "Huh?");
break;
}
}

That is: braces always line up, and use 4-space TABs (I'm using spaces above since not 
all email programs expand TABs the way I'd like them).

I hate the way MS lines the case statement under the switch statement.

Yikes!! :-P Thanks Dave for that piece of info. Apologies for the 
misinformation guys.

Dave, would you please take this opportunity and let us know furhter 
in this direction ? I have read somewhere that palm devices dont have 
any MMU. 

Let me keep it in this way please...My understadning is that Palm OS 
does not have any virtual memory...so its all segment/chunk oriented 
stuff. Does that the reason why any resource in Palm cannt be larger 
than 64K ? And thencannt I hide the physical addresses behind the 
handles ? I thought a handle is really a pointer to pointer. I 
particularly wanna know more on how does the system make up for lack 
of a typical MMU ?

There's not a really easy way to do it.  You're going to have to mock up
a few elements yourself to make this work.

You can put a scrollbar widget on top of the listbox widget in the GUI
designers, so that's easy enough.

The tough part, though, is that you'll have to set the scrollbar's
appearance when the form opens, when the number of items changes.  

When you change the scrollbar, you'll have to redraw the listbox
(whether through a custom list draw function, or by changing the set of
strings the listbox points to.

RE: pilrc rcp files and chinese characters

[Ken Krugler]

Hi there,

I'm answering this based on some slightly out-of-date pilrc source 
that I've got, so it might not be accurate for the latest version.

}I saw that pilrc supports GB/BIG5. Now which characterset must=20
}my rcp file be in? I mean, it could be UTF-8 or BIG5 or=20
}whatever.
It has to be in the corresponding Windows code page, which is what 
Palm devices typically use for their charset. So if you're doing 
Big-5, then the input text is CP950 (basically Big-5), and so on.

How do I tell pilrc which characterset I used to=20
}encode my rcp file... Or is it always a certain format and=20
}some escape sequences. In Java for example you can encode=20
}unicode characters like so: "\ua0b0" (unicode character 0xa0b0).
Check out the pilrc manual's description of the -F command 
line parameter. For example -F5 for Big-5, -Fg for GB. Based on this 
setting, pilrc assumes that the input file uses the corresponding 
character encoding.

Re: LstGetSelectionText() - Memory Allocation ?!?!

[Alan Ingleby]

I doubt they'll every add it, since the existing API is capable of doing the
job.

Besides that, it's possible to simulate a "text callback" using the existing
API.. Simply use the userDataP to hold your function pointer, then you only
need to write one ListDraw function (which then calls your "text callback").

Easy huh?.. Take about 15 minutes to write it the first time, stick it into
your standard "library" code, get the exact functionality you need, and it
only adds 10 lines of code to your whole project.

BUT... I am noticing now that there are two PalmOS.h files on the

/opt/palmdev/sdk-4/include/PalmOS.h

I had tried to install prc-tools from sourceforge before I went to 
palmos.com -- so maybe it's still trying to use the failed sourceforge 
install.  In fact I'm pretty sure it is, because if I rename the one in 
/usr/share, make yields "PalmOS.h: No such file or directory".

This is a newly installed redhat with nothing else on it, so I do have 
the luxury of being able to reinstall absolutely everything from scratch 
and know what I'm dealing with.  That might be the next step.

Re: memory leak -- but where?

[rguevara]

Hi, use Char nameP[8]=['\0','\0','\0','\0','\0','\0','\0','\0'];
and close all forms in the stop application routine with FrmCloseAllForms(),

What I'm talking about is allowing a program (a geocaching database, in my
case) to run the mapping program, while passing a set of coordinates (via
the cmdPBP parameter for SysUIAppSwitch()) to mark a waypoint on the map
(optionally with a name for it), so you can find it there in relation to
where the GPS receiver tells you that you are.

Mapopolis does this with street addresses, and allows passing a creator ID
to return back to when a "Done" button was tapped that it would display in
that situation.  If they accepted GPS coordinates to do the same thing,
then that would be a perfect example.

Replace Substrings

[Jim Duffy]

Hi all,

Does anyone know a way to search through a string for all instances of a
substring and replace them with a different substring?

For example:

string1 "This[CR]is a [CR] Test"

I need to replace all the "[CR]" with the '\n' newline character..

I've tried using StrStr() and TxtReplaceStr() but these aren't really cut
out for this.  Can't find any other API that might work..

Thanks for the help..

Your example is character replacement, which can be achieved by:

//   substitute Char  c1 with Char c2
Char *ptr = string1;
while ((ptr = StrChr (ptr, c1)) != NULL) {*ptr = c2; ptr++;}
For substring substitution in-situ, you can use:

// Substitute Char *str1 with Char *str2, using shortest length
Char *ptr = string1;
UInt16 len = (StrLen (str1) > StrLen (str2) ? StrLen (str2) : StrLen (str1));
while (len && (ptr = StrStr (ptr, str1)) != NULL) {
StrNCopy (ptr, str2, len):
ptr += len;
}
Fully handling substrings of unequal size is a tricker because you have to 
make a copy of the original string and copy it back to the original string 
in segments, inserting the new string as appropriate.  Someone else 
provided an example of that.

RE: Breakpoint stopping code, But I removed it!

[Ben Combee]

I fixed the problem - it's not the IDE, it was just coincidence that the
line that I had the breakpoint on (the diffC =...) did not cause an
error when you stopped on it, then continued, but failed miserably when
run at "full speed". The difference lies in the treatment of pointers.
As far as I knew this should work (tho I can't recall ever doing it
quite this way before):
Int16  * NumberTimes1Ptr, * NumberTimes2ptr
NumberTimes1Ptr = (Int16 *) ((UInt32)rec1 + FishStr1Len
+ 1);
NumberTimes2Ptr = (Int16 *) ((UInt32)rec2 + FishStr2Len
+ 1);
diffC = *NumberTimes1Ptr - *NumberTimes2Ptr;
If this code, the computation of diffC would fail if either NumberTimes1Ptr 
or NumberTimes2Ptr were misaligned (on an odd address).  Any 16-bit or 
32-bit memory access on the 68K must be on an even memory boundary.

It doesn't, at least not with CW9. The following code DOES work:
Int16   NumberTimes1, NumberTimes2
NumberTimes1Ptr = (UInt8 *) ((UInt32)rec1 + FishStr1Len
+ 1);
NumberTimes2Ptr = (UInt8 *) ((UInt32)rec2 + FishStr2Len
+ 1);
MemMove(&NumberTimes1,NumberTimes1Ptr,2);
MemMove(&NumberTimes2,NumberTimes2Ptr,2);
diffC = NumberTimes1 - NumberTimes2;
This works because you use MemMove to copy the values into aligned memory 
first.

NormalLaunch doesn't accept arguments, but some PalmOS applications
support other custom launch codes which allow an argument parameter
block to be passed in.  (Minicalc and HanDBase are 2 examples.)
sysAppLaunchCmdGoTo and sysAppLaunchCmdFind are other examples
of a launch codes which includes parameters.  And there are a few 3rd
party utility applications which will allow one to insert CmdGoto
parameters on a "command line".

Nice to see I'm not completely full of bad ideas Mind you, I'm surprised
Aaron hasn't chimed in with advise on replacing all calls with MemMove,
wrapped around a liberal sprinkling of Semaphore tinkering. :-)

Todd, as you can see, you're not heading down the right path.  If you're
going to find it difficult to keep track of the type of pointer you're
dealing with, the legal way of handling your requirement is:

#define SafeUlgyDmWrite(a,b,c,d)
{MemPtrDataStorage(a)?DmWrite(a,b,c,d):MemMove(a+b,c,d);} /*Note - Untested
code... Use at you're own risk!!!*/

You can now use the aptly named "SafeUlgyDmWrite" to replace all your
DmWrites, and not care whether they're into Dynamic or Storage Memory.


Let me know if this helps.

yes. 

simple proof = 320x320 @ 16bpp = 204800 bytes. any OS5 device can do 
that *g* you say you want a 640x480 buffer - you should probably 
stick to the size of the screen and only render what is needed.
(ie: basic windowing techniques)

The problem is that PalmSource changes the type you pass to that routine to 
take UInt16 rather than Int16.  You need to adjust the actual type of the 
function you were passing in to use UInt16 rather than Int16 or SWord values.

Porting Tool(s)

[Alan Ingleby]

Does anyone know if there are any porting tools for PalmOS -> PocketPC?  I'm
not asking for info on a multi-platform development environment (SHARK,
Java, Basic etc..) as these typically require rewriting most of your code.

I'm interested in a C API layer that wraps PalmOS calls to equivalent
PocketPC calls.  A resource cross-compiler would be nice.. I guess fairly
easy too, due to the Open Source nature of PilRC.

It's just that I'd like to be able to take most of my code, and compile it
in eVC3.

I understand that this is a seemingly ridiculous question, but it's worth
asking, before I go jumping into doing it all by myself.

I'm in the process of finishing up a rather large program (190K+) and would

row shading (like Pocket Quicken does).
No problem if you do custom drawing for the table cells.  You can draw each 
row independently, which allows you to use different foreground and 
background colors and to display different parts of the cell in different 
ways.  This is also the easiest way to do framing.

If you're going to program in C, you have to know pointers. Unfortunately,
I don't know of any good books in that regards, because I cut my teeth
on pointers using an obscure language for the Atari 800 called
Action. It was so close to the metal that it makes C look like Visual
Basic. However, it did teach me what a pointer was, so when I started
learning C I already understood them.

I think if you ask on any C forum, they'll have lots of suggestions. It's
probably even in a FAQ somewhere.

No, I'm not. It's straight C.

Here is some psuedo-code. It's been years since I even compiled
my list builder code. It's in CVS someplace and I don't feel like
getting it out, but I did compile this. It gobbles down the 
INCREDIBLE sum of 208 bytes of code space.

char** buildList(int listWidth,int cnt){
int amt=cnt*(sizeof(char*)+(listWidth+1));
int i;
char **theList=(char**)MemPtrNew(amt);
char *dest=(char*)(&theList[cnt]);

//If you want to be stingy:
// WARNING: *Grossly* complicates the deallocation to TWO
// statements:
//MemPtrFree(theList[0]);
//MemPtrFree(theList);
//char **theList=(char**)MemPtrNew(cnt*sizeof(char**));
//char *dest=(char*)MemPtrNew(cnt*listWidth+1);
//UInt32 memUsed=0;

for(i=0;iand also violates the coding practice of trying to unallocate
>memory from within the same function in which it was allocated.  

You evidently have no experience with 'Lazy evaluation'.
Never heard of your 'coding practice'.

The fact is, if the global is not null, there is memory allocated to the list.
You need to de-allocate before allocating again. If you like, I'll
move the clause to a separate function, OK?

Your '??' on the setting of pListText to NULL makes me think
you don't get it;

Leaving the de-allocation of the prior list to the list builder
function is what makes memory handling simple. Any time you build
a list, it cleans itself.

>I'm not
>saying either way is wrong... Just offering reasons why some people choose

What you *are* saying is that you don't have much experience with
allocating/deallocating memory for dynamic lists.

The two of you are talking about 2 different things.  Although total
dynamic heap size is fixed by the hardware vendor, the amount of 
available
dynamic memory is not, as it may be affected not only by "hacks", but by
display depth, network driver status, whether any OS upgrades have been
installed, background sound threads on newer models, etc. etc.

Because of this, it is important to test an application with much less
dynamic heap available than the default amount available on a clean idle
handheld after a cold boot.

the post belongs to the communication forum, but i´ll give you my code, i

By the way,  the timeout occures when the header isn´t formatted properly, i

Err err;
UInt16 AppNetRefnum;
Int32 AppNetTimeout;

Char strX;
Int32 plongAddress;

MemSet (textP, sizeof (textP), NULL);

AppNetTimeout = SysTicksPerSecond() * 10;

SysLibFind("Net.lib", &AppNetRefnum);
NetLibOpen(AppNetRefnum, &err);
mySockFd = NetLibSocketOpen(AppNetRefnum, AF_INET, SOCK_STREAM, 0,
AppNetTimeout, &err);

plongAddress = NetLibAddrAToIN(AppNetRefnum, "server.ip.in.numbers");

mySockAddr.family = netSocketAddrINET;
mySockAddr.port = 80;
mySockAddr.addr = plongAddress;

NetLibSocketConnect (AppNetRefnum, mySockFd, (NetSocketAddrType*)
&mySockAddr,
sizeof(mySockAddr), AppNetTimeout, &err);

// add a blank line to the body
if (!WriteLoginRequest (Request))
return;
StrCat(Request,"\n");

// create the Header, including a blank line
StrPrintF(cpSendBuf,"POST /myapi.oxp HTTP/1.1\r\nHost:
www.myserver.com\r\nContent-Length:%u\r\n\r\n", StrLen (Request));

// send Header
NetLibSend(AppNetRefnum, mySockFd, cpSendBuf, StrLen(cpSendBuf), 0, 0, 0,
AppNetTimeout, &err);

// send body
NetLibSend(AppNetRefnum, mySockFd, Request, StrLen(Request), 0, 0, 0,
AppNetTimeout, &err);

myHowMany = NetLibReceive(AppNetRefnum, mySockFd, &textP, sizeof (textP), 0,
NULL, 0, AppNetTimeout, &err);
FrmCustomAlert(ID_APP_ERRORALERT, "", textP, "");


NetLibSocketClose (AppNetRefnum, mySockFd, AppNetTimeout, &err);
NetLibClose (AppNetRefnum, true);

return;
}
thats it. WriteLoginRequest is the function to write the request (the body
of the post), you have to add you own.

Hope this will save your time.

Re: using versamail and the exchange manager

[Manohar Chapalamadugu]

I don't really know whether Versamail supports
Exchange Manager. However, the best way to send an
email using Exchange manager is to use the mailto URL
scheme. You need to get the registered application(s)
and popup a screen asking the user to select the email
app. The default application (maynot be Versamail),
registered to handle mailto, will pick up and add the
mail to its database. However, this approach works on
=+4.0

Good luck.

This is a very common functionality and as such, there are helper APIs
that will save you a lot of time, Ricardo.  You can get a list of all
files on the device with SysCreateDataBaseList().  For example:

-
MemHandle haItems  = NULL;  // Handle to array of SysDBListItemType
UInt16wNumDBsFound = 0; // # of SysDBListItemType items in
haItems

SysCreateDataBaseList( sysFileTApplication, 0, &wNumDBsFound, &haItems,
true );
-

Once haItems is generated, you can load up a list control with the
strings inside the SysDBListItemType.name member (see
http://tinyurl.com/jws9 for info on generating a list's contents during
runtime):

-
SysDBListItemType* paItems = NULL;
if ( haItems )
   SysDBListItemType* paItems = (SysDBListItemType*) MemHandleLock(
haItems );

if ( paItems )
{
   for ( UInt16 i = 0; i < wNumDBsFound; i++ )
  AddStringToMyList( paItems[i].name ); // Analogous to
FillListWithYears()
// in the List recipe URL
}

MemHandleFree( haItems ); haItems = NULL;
-

Once a user has selected one of the items from the listbox to beam, you
want to lock down haItems again, advance to the index corresponding to
the user's selection, extract its name, creator ID, and dbID, and then
use the Exchange Manager to send the file.  BE SURE to MemHandleFree(
haItems ) at some point after you no longer need it, or else you will
leak the memory allocated to store the array.

See http://tinyurl.com/jwrd for sample code of how to send a database
using the Exchange Manager.  The only thing I would add to this recipe
is to use one of the prefixes defined in http://tinyurl.com/jwr7 so that
your user is prompted whether they'd like to send (Bluetooth) or beam
(IR) or SMS the file, depending on the capabilities of the device on
which your app would be run.

See the bottom of http://tinyurl.com/jwrw for a sample WriteProc() that
should work for your ExgDBWrite() call.  

I hope this gets you going.  Be patient with the Exchange Manager, it
can be fickle, but once you've beamed a file through thin air, you
realize it was worth it.  At least, I did.

Re: lists (how to change scrollbar look & feel)

[Dave Lippincott]

Draw the list and the scroll bar.  Handle the scroll bar messages and update
the list manually.  Its not as hard as it sounds.  If your app displays a
scroll bar and handles the events, you can force the list to do whatever you
want.  As far as not displaying the list scroll arrows, you can set the list
up with just enough lines to fill the screen once and handle tracking which
items are visible/selected.  You can do this with a list, table or custom
gadget.  Its easiest with a list. (IMHO)

RE: Palm Emulator

Yes, that's bad.  You must pass it a valid pointer to an existing
FieldAttrType object which you supply yourself:

FieldAttrType fldAttr;
FldGetAttributes (fldP, &fldAttr);

Otherwise, how would your original version work?  How would the
attribute information be returned to your program?  Is there any way for
FldGetAttributes to modify your passed-in pointer to point to something
the function itself might allocate?

(Do these sound like questions from a programming teacher? :-)

Re: How know the name fields of PDB file

[Thomas Damme]

Hi,

some CSV->PDB Converters store the field names in the AppInfoBlock of a
database. Take a look at DmDatabaseInfo to retrieve the AppInfoBlock if it
is there. Some FileManagers also show you, if a InfoBlock is there so check
this first before you do too much work.

Thanks Ben, actually I've been reading up at the CodeWarriorU site about
C (as well as another C book) and such but haven't gotten to pointers yet.
These are the problems I was afraid I'd run into when starting this
project.
Thanks for your advice, I'm certainly taking it.

Don't use the "Enable C++ Compilation" switch in CodeWarrior.  CW will

Re: UI internationalization?

[Ken Krugler]

I want to make my UI application internationalized . What is the procedure
to start with this .
Read the "Localized Applications" section of the Palm OS Companion 
documentation.

From where can I get the overlay resources ?
You don't need these to create a localized application. Overlays are 
a technique (mostly used internally for multi-lingual EFIGS ROMs) to 
separate out the non-localizable portions (mostly code) from the 
resources that should be localized.

What else
should I do to make the application support internationalisation ?
If you still have questions after reading the "Localized 
Applications" chapter, please re-post specific questions.

How can I
test the Japanese , etc. charactors / words ( I don't know Japanese ) on my
application ?
Once you've got the Emulator or Simulator running with a Japanese 
ROM, running Gremlins is the easiest first step.

This is non-standard Palm OS UI.  There is no support in Palm OS for grayed 
controls.  In general, disabled controls are hidden on the screen, or they 
are left active with an alert telling the user why the control isn't valid 
right now.  Look at the "Details" button in To Do for an example.

Re: new and delete in Palm

[Ben Combee]

The 64K limitation I think is an arbitrary choice. If I recall
correctly, the chunk header allows up to 16M chunks, but they limit it
to 64K because the hotsync protocol only supports up to 64K record
sizes.
Palm OS 1.0 and 2.0 had memory heaps that were limited to 64K, so it wasn't 
actually possible to allocate a block of memory larger than that 
size.  This heap structure was reworked in Palm OS 3.0, but the HotSync 
protocol wasn't fixed to support these large chunks.  Palm OS 3.5 provided 
a back door to allocating large chunks, and this is used by the 
MemGluePtrNew call in the glue library included in Palm OS SDK 5.0 R2.
