Re: How do I update memory
Hi Jeff, I think you have to join what Palm calls the development Provider Solution (?). When Palm accept you as a member, it takes a while for them to send you the password. You use your email account (that you register with them) and the password they give you to log in. tnn Heather Tufts wrote: > The updates are embedded in the 3.5 SDK and the Update 1 to the 3.5 SDK. > Also, there are a couple of debugger plugins hosted on the Metrowerks > Website which you can download for Mac or Windows at > ftp://palm:[EMAIL PROTECTED] Those are all the public updates at > this point.

help, please!!!bugs in palm program
Hi the experts, I am some bugs in my program but can not catch them and fix them. Please help me. I run the program the 1st time, inside the program, I get "index out of range" error. I have to reset the program. I run it the 2nd time, I get "bus error", the program doesn't run. I have to delete it and load it back before it can be run again. I step through the program, set break points all over the places but in the middle of the program, after one breakpoint, before the next break point, I get "index out of range" error. I step throught the program, step by step, sometimes the program jumps into the Assembly code, then jump back to my code. After a while, it goes in the evenloop and I miss the message sent back from the serial port, the program behaves differently... (I should get the message from the com port, process that message and so on). When the program jumps to the Assembly code, doesn't it mean it catch an exception? I am checking the code to make sure I don't have the "out of range" bugs when I access the database. I check to make sure I do not overflow the strings in my program. What else I should check? I think I may have bugs because word alignment. Please tell me what I have to do. I can duplicate the bug but can not catch it. What can I do? Thank you for your respond. tnn --- FREE!

Re:How to align a label in a table
Hi there,
> How can I align the label to the left?
I don't know if there is better way to do it. This is what I do, I make the
table with 1 col and fill data in using WinDrawChars()
I forgot where I took this code, must be in an example code.
// Determine the length of text that will fit within the bounds.
// data to put in col1 is in tempstr1, col2 is in tempstr2
width = bounds->extent.x - 45;
textLen = StrLen(tempstr1);
FntCharsInWidth(tempstr1, &width, &textLen, &fits);
// if the string is too long, add "..." at the end where it is cut
if (!fits) {
WinDrawChars("...",3,width,bounds->topLeft.y);
}
// Now draw the text from the record.
WinDrawChars(tempstr1, textLen, bounds->topLeft.x+1,
bounds->topLeft.y);
leftbound = bounds->topLeft.x+125;
WinDrawChars(tempstr2,StrLen(tempstr2), leftbound,
bounds->topLeft.y);
hope that helps.

What happens when user tab the silkscreen/hard buttons?
Hi everyone,
Please help me with these questions:
1. While my program is running, if the user tabs on the silkscreen buttons or
the hard keys, does the FrmCloseEvent invoke? and the AppStop() will be called?
2. At a certain point in my program, I want to ignore anything the user tabs on
the silkscreen (except the "cancel" button in my form), I set handle to true in
keyDownEvent but it doesn't seem to work. What do I have to do?
3. I have a dialog form in my program ("save behind" is checked), when user tab
a button on this dialog form, the window doesn't redraw completely. Part of the
screen is erased, do I have to redraw everything to make sure? I think,
supposely, we don't have to that.
4. I have a table in my form, when I select a row, I show a information window
about that row (dialog form). If the row I selected is outside the dialog form,
when I close the dialog form, it is OK. If the row is hidden, when I close the
dialog form, it is not highlighted anymore. What can I do? I try to select the
row afterward but it doesn't highlight either. Is this the same problem as 3 ?
Please tell me about anything that you may think of to solve these. Any help is
very appreciated.

Can anyone confirm this? If so, why isn't it? Yes, I think dataprv.h is no longer in Palm 3.5. I don't know why. What I did is I look at dataprv.h, copy the structure defined in there to my program, simplify it and use it. I change some variable typed structure to a generic datatype. I also have to change (I think a lot) in the name of datatype so my program can run under Palm3.5. Mainly, I use UInt8, Int8, UInt8*, Int8*, UInt16.. for all of my variables. Palm 3.5 doesn't support Ptr (CharPtr, MemPtr...) So you have to use Char*, MemHandle. There is a header file you can include (*compatibility.h or st) but it doesn't cover everything so I go ahead make the changes once. If you use a good editor, it won't take too long to make all the changes. There is some documents in Palm dev zone about Palm 3.5 that may help, too. tnn --- FREE!

FrmGetFormPtr(), gadget, PRC to Overlay?
Hi everybody, I am learning to use PRC to Overlay tool in Palm. I have a form with 3 objects. I want to make an overlay PRC with just 2 objects. I get stuck because I don't know how to do this: 1. If I call FrmGetFormPtr() in AppStart(), it return 0. If I call FrmGetFormPtr() or FrmGetActiveForm() in frmOpenEvent, it works fine. Why ? 2. If I'd like to find whether an object is existing in a form or not, can I do it or not? which API can I use? 3. I have a gadget in my form, I do some custom draw (WinDrawLine(), etc.) in the gadget. When I set gadget unusable (uncheck the usable box), it still draws. Why? How do I check the value of usable of that gadget? How do I set the value of usable of that gadget? Can anybody tell me how to do 1. 2. 3. or how to make an overlay PRC with 2 objects. Is there any more documents about PRC to Overlay other than 7 pages OVERLAY TOOL from Palm site?

Re: FrmGetFormPtr(), gadget ???

My stupid question, FrmGetFormPtr() only return the form pointer when the form is in memory, which is when frmLoadEvent is queued( when we call FrmgotoForm() or FrmPopupform()), why do we need FrmGetFormPtr(formID) while we can use FrmGetActiveForm()? >Is this an extended gadget and are you using the 3.5 New Feature Set?

Is >your gadget handler responding to formGadgetDrawCmd and formGadgetEraseCmd? >If not, then the gadget is really not much more than a screen area you >define so you can later get it's bounds. For some gadget, I just need to bounds, for some other gadgets, I do need to define and setup the gadget handler. The gadget handler is called when user tab inside/outside the gadget. I need the gadget to draw w/o user control. I am hoping that when I set the gatget unusable, it won't be drawed.

re: Differance between .pdb/.prc file and File Streams
Hello there, In the Palm Doc section somewhere, you can find the File format document, which tells you the formats of different Palm files (PDB, PRC, PQA). Using the exchange manager, you can convert the resource database to .PRC file. You can also convert the record database to .PDB file. I used to transfer files between the Palm internal memory and the external memory (SD card) using exchange manager. At that time, we didn't have pictures as jpeg file on the Palm, so I don't know if it works differently for .jpg file. I use file streaming as data buffer instead of allocate a big chunk of memory. You mention that you got duplicate data and extra data when you transfer the file. I suggest to test these 2 steps seperately. 1. Using ExgDBWrite to convert to .prc or .pdb file Instead of transfer the file after converting it, just save it in the SD card, then you can compare to see if your .prc or .pdb file is exactly the same as the original file or not. 2. transfer using netlib. Instead of transfer the file, just transfer some data (100 bytes data) and see if you receive that data at the end. If the 2 steps work OK, then you put them together and try with small file ( < packet size), then with bigger file... Hope that helps. tnn -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

What is the 1st param in SysLibInstall( , ) ? How to use SysLibInstall()
Hello everyone,
First, I am sorry for the long email. I don't know how to write it shorter.
I want to run my application from the "send contact" menu in the contact
(address book app).
I read the recipe in Palmsource about running the application from the send
menu,
The recipe said
Begin quote
...
Check that the library is not already installed:
...
if (! SysLibFind(kSmsLibName, &refNum))
return;
Then install the library. This sets up the dispatch table and registers the
exchange library with the Exchange Manager:
if (!SysLibInstall(MyInstallDispatcher, &refNum))
...
End quote
I need to check and install the local exchange library, not the Sms lib
After checking the lib if (SysLibFind(exgLocalLibName, &refNum)), how can I
install the library using SysLibInstall()? I don't know how to get dispatch
table (MyInstallDispathcher). The recipe makes me think it is simple to use
SysLibInstall()
I follow the function AESLib_LoadLibrary() in AESLib_inline.h and do this
Err LoadLocalExchangerLibrary()
{
Err err;
MemHandlecodeRscH = 0;
SysLibEntryProcPtr codeRscP = 0;
UInt16 cardNo = 0;
LocalID dbID = 0;
DmSearchStateType searchState;
DmOpenRef dbR = 0;
SysLibTblEntryPtr entryP = 0;
Boolean libInROM = false;
UInt16 refNum;
DmGetNextDatabaseByTypeCreator(true, &searchState, sysFileTExgLib,
sysFileCLocalLib, true, &cardNo, &dbID);
if (!dbID)
return sysErrLibNotFound;
libInROM = (MemLocalIDKind(dbID) != memIDHandle);
if (0 == (dbR = DmOpenDatabase(cardNo, dbID, dmModeReadOnly)))
return sysErrNoFreeRAM;
if (0 == (codeRscH = DmGet1Resource(sysResTAppCode, 1))) {
// I got stuck in this line, codeRscH is 0
// what should be the value of the 2nd param
// in DmGet1Resource() in this case?
ErrNonFatalDisplay("Can't get library rsrc");
err = DmGetLastErr();
err = sysErrLibNotFound;
} else {
codeRscP = (SysLibEntryProcPtr)MemHandleLock(codeRscH);
err = SysLibInstall(codeRscP, &refNum);
if (!err && !libInROM) {
DmDatabaseProtect(cardNo, dbID, true);
}
}
DmCloseDatabase(dbR);
dbR = 0;
if (err) {
refNum = sysInvalidRefNum;
if (codeRscP && !libInROM) {
MemPtrUnlock(codeRscP);
DmReleaseResource(codeRscH);
}
} else {
entryP = SysLibTblEntry(refNum);
entryP->dbID = dbID;
if (libInROM) {
entryP->codeRscH = 0;
} else {
entryP->codeRscH = codeRscH;
}
}
return err;
}
Could someone please tell me what I do wrong.
Also, in the recipe, toward the end, it said "If the application has multiple
segments, you have to load and lock each segment that contains a part of the
Exchange Library."
My application has multiple segments, which segment will contains a part of the
Exchange Library? How do I know? Could you explain to me, please.
Many thanks for reading my email and for your help.

Can you draw a smaller bitmap from the external card? If not, try that first. > WinDrawBitmap(someBitmap,0,0) Input data someBitmap (of WinDrawBitmap()) is in the Palm bitmap format (bitmap family, check the "Palm OS Programmer's Companion"). It is a lot different than the format of images (.bmp,.gif, .jpg, etc...) If you can load the image in advanced, cut the image to smaller size imagees and put them in the resources (using Constructor). If you have to load the image at runtime http://flippinbits.com/twiki/bin/view/Main/DevelopmentToolsList has links for some image related libraries. I tried to show images at run time on the Palm but I couldn't get the right color table (color pallete) and I gave up. If you find out how to draw bitmap from external card, let me know too, please. tnn -- For information on using the PalmSource Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
re: Convert Int16 to UInt32?
I believe you (that it works before and doesn't work now)...
I think it should work. May be try to cast it.
Int16 num_bytes_read;
num_bytes_read = NetLibReceive(..);
// If you need the variable new_buffer_size for anything then
// do UInt32 new_buffer_size = (UInt32)num_bytes_read;
// otherwise ...
UInt8 *buf = NULL;
if (num_bytes_reads > 0) {
buf = (UInt8 *)MemPtrNew((UInt32) num_bytes_read);
// type cast to (UInt8 *) or to whatever you define buf
if (!buf) {
// error
} else {
// use buf
}
}
Hope it works,

If you just need multiline text field without the scroll bar, (I am using CW, I don't know how to do it in Pilrc) In the contructor, you put a text field with the height = number of lines x 11, set to multiline (uncheck single line, maybe) In your code, use SetFieldText(), GetFieldText(), FreeFieldText() to work with text fields.

When you say "the app doesn't return the user to HOME", what do you get? the blank screen until you reset the Palm? I don't think it is the problem with FrmGotoForm(). If you return false in frmCloseEvent of a form and call FrmGotoForm() to go to a form, it always works fine. If you put a main button (to go back to Main form) in your secondary form, when user presses that button, then exits the program, does the problem happen? You can also test it by writing a small program with some forms, the secondary form has a list, when you cloose an item, automaticaly go back to the main form, does the problem happens? If the problem happens, then it may have st to do with the list (memory for the list items?) When I have a bug in my app, the app just behaves weird until I fix the bug. tnn __ Do you Yahoo!? Yahoo!

Can I debug the program on the SD card?
Hello all, I am writing a Palm program for the Tungstens and it works fine on the Internal memory but if I put it on the SD card and run it, I get the Fatal Alert saying "MemoryMgr.c, Line:3564, NULL handle". Tapping on the "Reset" button in the Alert doesn't work, I have to do hard reset. I use CW 9.2, Window 98, testing on TT, TC and TT2. How can I debug to find the error? My program first looks for the SD card, then reads files on the SD card (using VFSManager) and reads files on the intermal memory (using FileStreamManager) and display those files on the screen. I can not debug my program using POSE or SIM because they don't support the sound manager. What does the OS do when we run a program from the SD card? Does my program do something that conflict with what the OS does? What do I have to do or check? Do I have to do this: Telling the user that my program won't run from the SD card.

Re: Bitmap PDB

Re: Need help using TblGetItemPtr - getting wrong data
Hi there,
I read your posts about TblSetItemPtr() and TblGetItemPtr(). Both of these functions
are available
on PalmOS 3.5 so you don't need to use
tableP->items[row * tableP->numColumns + column].ptr
I didn't use TblSetItemPtr() and IblGetItemPtr() before. I do use TblSetItemInt() and
I always set
it to be the record number (in the database).
What is the code around your while loop ?
/* Put the data after the time, if any, into the table ptr item. */
CharPtr pRec;
Char szEndPoint[ 30 ];
Int16 nDay = 0;
StrCpy( szEndPoint, "1534f" );
Char ch = szEndPoint[ nDay ];
/* Go through string looking for the first non-numeric char. */
while ( ch && ch >= '0' && ch <= '9' )
{
nDay++;
ch = szEndPoint[ nDay ];
}
if ( ch )
{
pRec = szEndPoint + nDay;
}
else
pRec = NULL;
TblSetItemPtr( pBusTimes, i, nColumn, pRec );
How "i" and "nColumn" effect "szEndPoint" ?
>From your code, pRec is &szEndPoint[4] , so the value is the string "f" until you
>modify
szEndPoint, the value may change.
I think the memory that "pRec" points to in TblSetItemPtr() must be available for the
table
pBusTimes during the life time of that table.
I would think on your table, each row will have different value (not "15:34 ?", ? is a
character).
If you take these values from a database, may be you just need to set TblSetItemInt()
to record
number and in your custom draw function, you retrieve the record by the record number
(index of
the record) and draw... That is what I saw in the samples program and I always do that
in my
programs.
The memopad project (tutorial) shows you how to do all of these.

I hope Shortcut Dot Dot Two works for you. Also, you can try to build the program "Dot Dot Two". The project should be in the CW example folder, 2K DotDotTwo.prc file works. I haven't tried the 515 for a while but I think there is no different from 515 and other Palm devices. tnn __ Do you Yahoo!? Yahoo!

Re: getting field text and padding
Hi there, As I said, the input string must be at least maxlen+1 (which is 16). You overwrite every string. Char a[15] = "123456789"; // should be Char a[16]; Char b[15] = "987654321"; // Char b[16]; Char c[15] = "741852963"; // Char c[16]; PadStringWithChar(a,15,' '); // maxlen = 15 PadStringWithChar(b,15,' '); PadStringWithChar(c,15,' '); //when i put it through the debugger i found that: //a ends up being "123456789 " //b ends up being "" //c ends up being "" Also, you may want to read about global/local variables and scope of a variable.

Re: getting field text and padding
Hi there,
To get the text in the field, search the archives for textfield or SetFieldText(),
GetFieldText(),
FreeFieldText()... These functions are in almost every Palm books that I read.
After you get the string from your text field, you can pad it with this function (no
compiling and
testing ...)
// <->inString, string before and after padding
// -> maxlen, string len after padding
// -> ch, the character that you want to pad to the inString
// the input inString must have enough room for at least maxlen+1 characters.
//
void PadStringWithChar(Char *inString, UInt16 maxlen, Char ch)
{
Int16 i;
UInt16 len;
len = StrLen(inString);

I set time.minute and time.second, I never use the time.frame. You can try both and if

Re:Hide and Show bitmap object as other objects,and then, move it..
>I want to Show and Hide bitmap just as other object (label, for example) but
>it seems that the function FrmShowObject does not work.
FrmShowObject always works for me. I hide/show bitmaps/graphic buttons.
Let say I have 3 graphic buttons btn1, btn2, btn3. They are the same size and same
position.
What I always do is:
To show btn2
HideObject(btn1);
HideObject(btn3);
ShowObject(bnt2);
To show btn1
HideObject(btn2);
HideObject(btn3);
ShowObject(btn1);
and so on ...
void HideObject(UInt16 id)
{
UInt16 obj_index;
obj_index = FrmGetObjectIndex(FrmGetActiveForm(), id);
FrmHideObject(FrmGetActiveForm(), obj_index);
}
void ShowObject(UInt16 id)
{
UInt16 obj_index;
obj_index = FrmGetObjectIndex(FrmGetActiveForm(), id);
FrmShowObject(FrmGetActiveForm(), obj_index);
}
Have you try that?
I don't know how to move object, though.

Re:Emulator that suports Memory Sticks?
Hi there, As I remember, the Sony emulator for N710/N760 supports MF (supports VFS). When you create a section, you tell it the size (16, 32, 64, 128 ?), then you can drap whatever you want to put in the MS to folder MS128 (or MS64, etc...). It has been a while so I don't remember if the emulator for NR70 support MS or not, it should and so should the later Sony Emulators.

Re: FrmPopupForm???...
Hi Dan,
I remember people said st about FrmReturnToForm(0) before. (Search the forum for
FrmReturnToForm
:) ) So, I never use it. What I did is:
Let say you are in FromA, you will show FormB (modal form), then you go back to FormA.
I only use
the pair FrmPopupForm() and FrmReturnToForm() for modal form.
UInt16 backFromFormB = 0;
...
backfromFormB = FrmGetActiveFormID(); // I call this right before FrmPopUpForm()
FrmPopUpForm(FormB);
...
//When you are about to go back to FormA
FormBExit(); // do anything you want to do in frmCloseEvent of formB
if (backFromFromA) {
FrmReturnToForm(backFromFormB);
} else {
FrmReturnToForm(FormA);
}
I guess you can always call FrmReturnToForm(FormA); if you are sure about that.
One thing to remember is FrmReturnToForm() doesn't generate frmCloseEvent for FormB,
so you want
to do whatever you need to do before you go back to FormA in FormBExit(). Also put
FormBExit() in
frmCloseEvent of FormB because it will be call when you are in FormB and the user
exits your
program.
In debugger, when you are in FormB, if you set a break point in FormAHandleEvent(), as
soon as
FrmReturnToForm() is called, I think it will hit the break point. If after
FrmReturnToForm(), your
program doesn't go to handle the event for FormA, where does it go?
You can try this, after FrmReturnToForm(), call FrmGoToForm(FormA), if you do that,
even you don't
have any code to update FormA, FormA still gets update OK, just the screen is
flicking. I did tell
you that last email because I think that is the quick and dirty way to do it but I had
to do that
before.
Hope that helps.

sample sound on Tungsten T?
Hi there, I'm trying to add voice recording and playback from a memory card to some applications using the OS5 sound API's. It appears that the buffer passed to the callback routines is not correct. It never changes even though audio is supposed to be double buffered, and whatever data is written to it does not have any effect on the sound coming from Tungsten T (OS 5.0). On the record the buffer contains random stuff, including some ASCII strings. If I use the SndPlayResource function to play audio then my sampled sound functions appear to play back a buffer from the resource audio over and over again. Anyone know how to get sampled sound API's to work on a Tungsten T? Also, the SndPlayResource with the Async flag appears to lock up the unit, but the Sync playback works OK. Is OS 5.1 the only answer? Also, does anyone know how to find and use the sound API on the Sony NX60 and NX70 devices? It appears they didn't implement the sampled sound API either.

reference a
memory location within a master pointer block."
The "Continue" and the "Debug" buttons are gray out, so the only thing I can do is
"Reset".
This is the snip code to set new text field, do you see anything wrong in the code?
Any idea or suggestion is very appreciated.

FldSetMaxChars( pField, nMaxSize-1);
FldRecalculateField( pField, true );
if(bRedraw)
FldDrawField( pField );
}
}
In the contrustor, the text field is set
usable
editable
underline
single line
not dynamic size
left justified
max characters: 64
This is the function call
Char authorstr[41] = "Thunguyet nguyen";
SetFieldText(RecordAuthorField, authorstr, 41);
Do I have to set dynamic size for the field because I have to set different text (with
different
length) for the field? Is that my problem?

RE: Transffer of the .PDB files...

Exchange manager converts between the file format on PC and > the database on Palm. I only use File Streaming as a very big buffer on Palm. this probably wouldn't help unless the PC understands the exchange manager. what needs to happen here is that the PDB needs to be "mirrored" piece by piece over a simple byte transmission (ie: ftp). on way to do this (as a hack) is to get the address of the pdb file and copy byte for byte, or, manually generate the .pdb file in a raw stream which is sent to the "receiving" client. :) One way to "manually generate the .pdb file in a raw stream" would be taking the data from Exchange manager, is that right? I use ExgDBWrite with the callback function to write the data to a file stream (as a buffer), then I use YModem to transfer the data to our device (removable hard drive when PC looks at it) For me, I think if we know what is in the database in Palm, then we can generate the .pdb file. Otherwise, I don't know what else I can do except using the exchange manager. Am I missing something? Could you explain it for me, please. > > I need know any manner of send a .PDB file to a Server via Socket. I tryed > > File Streaming API, but this not work, Do you know other manner ? Does he mean that when the data is in a file stream, he can't use fpt to transfer to PC? Thanks a lot. tnn __ Do You Yahoo!? Sign up for SBC Yahoo!

I use that for transfering files between Palm and PC. Exchange manager converts between the file format on PC and the database on Palm.

Why LstGetSelection() doesn't return noListSelection? Please help
Hello all, Please tell me what I do wrong. I am using CW 8 (update to 8.2) on the POSE ver 3.5 (m505 skin). I have a dialog form that has a popup trigger associated with a list. Content of the list is dynamically created inside the program. If user selects the 1st item in the list, LstGetSelection() return 0 If user doesn't select any item in the list, LstGetSelection() also return 0 while I think it should return noListSelection. Do I have to try to catch lstSelectEvent? Since this is a dialog form, I just want to get out of it when user press a button. I don't want to check any other event. How do I know that the list is no selected??? Thanks a lot for any help. tnn __ Do You Yahoo!?

Re: digitizer problem ...
Hi there, > Does anybody face the problem as a digitizer problem occurred when our palm > software installed. I have a similar problem. I have a Palm V and the digitizer doesn't work. I run the Welcome (build in) program to calibrate the screen again (or Pref -> digitizer) and the Palm seems to work OK until the next hot sync. Then, I have to calibrate again. I think, OK, not too bad, just have to do it once but I was wrong. Once, I try to play a game and the digitizer doesn't work... Now, I think it is the hardware problem. If this problem happens on one Palm device, I think it is not your software problem. If it happens on every Palm that your software is installed, then I don't know :( Hope that somebody would know. tnn __ Do You Yahoo!?

old and new serial mgr, SrmOpen() question.
Hi all, When I use old serial manager, before beaming, I have to close the serial port and open it again after that. What do I have to do when I use new serial manager? Do I have to close the serial port, open it using the logical portID 'serPortIdPort' SrmOpen(serPortIrPort, baudrate, portIDP); then after beaming, I have to close it and open again using the logical portID 'serPortCradlePort' SrmOpen(serPortCradlePort, baudrate, portIDP); Thanks for any help. tnn __ Do You Yahoo!?
