Hi Caspar,
with my project I ran into the same trouble. I craeted a "Killer.prc" that
deletes a copy of my "Main.prc" in RAM. The main routine is:
static UInt32 OJKPalmMain(
UInt16 cmd,
MemPtr /*cmdPBP*/,
UInt16 launchFlags)
{
Boolean newSearch = true;
Err err;
UInt16 cardNo;
LocalID dbID;
DmSearchStateType stateInfo;
switch (cmd)
{
case sysAppLaunchCmdNormalLaunch:
do {
err = DmGetNextDatabaseByTypeCreator(newSearch, &stateInfo,
sysFileTApplication, 'ABCD', false, &cardNo, &dbID);
newSearch = false;
if (!err)
err = DmDeleteDatabase(cardNo, dbID);
} while (!err);
break;
}
return errNone;
}
The above prc resides as the "start.prc" on my MMC. So, when the user
inserts the MMC to update my prc, a copy in RAM will be deleted
automatically.
Have you taken into consideration, that you need two programs? A "Main.prc"
and a "Kiler.prc"? If you try to delete the RAM-copy of your "Main.prc" from
within your "Main.prc" itself, it won't work.
To make sure, that the user won't be able to start the RAM-copy of my
"Main.prc" (that may accidentially reside in RAM), I use this in the AppMain
of my "Main.prc":
case sysAppLaunchCmdCardLaunch:
cardTypeP = (SysAppLaunchCmdCardType *) cmdPBP;
cardTypeP->startFlags |= sysAppLaunchStartFlagNoUISwitch;
FtrSet(cAppFileCreator, cFeatureNumVolRef, cardTypeP->volRefNum);
FtrSet(cAppFileCreator, cFeatureMMCLnchRef, 1); //Set flag "card launch"
break;
case sysAppLaunchCmdNormalLaunch:
err = FtrGet(cAppFileCreator, cFeatureMMCLnchRef, &theFeature);
if (!err && theFeature) {
FtrSet(cAppFileCreator, cFeatureMMCLnchRef, 0); //Unset flag "card
launch" and launch prc
err = FtrGet(cAppFileCreator, cFeatureNumVolRef, &theFeature);
if (!err) {
if (!(err = AppStart())) {
AppEventLoop();
}
AppStop();
}
}
else {
FrmAlert(RAMlaunchAlert); //User tried to start RAM-copy of prc, show
error message
}
break;

SysGetTrapAddress(sysTrapWinSetForeColorRGB) on some OS 3.5.3 devices
Hi all, haven't read news for a while, I don't know if this topic was discussed shortly... I had an issue with 3 users regarding a crash in one of my apps (FlugLotse). I found after some digging, that the call SysGetTrapAddress(sysTrapWinSetForeColorRGB) does not report SysGetTrapAddress(sysTrapSysUnimplemented) but something else, (0xffef) it was for one of them. The code snippet I use is directly copied from the Handspring Visor API docs: 5.2.1 Determing if 16 bit Color APIs are present it suggests to compare SysGetTrapAddress(sysTrapWinSetForeColorRGB) with SysGetTrapAddress(sysTrapSysUnimplemented) to decide if direct color API is available. But as it seems it fails on some Palm devices. But only until the next hard reset. Maybe some other application does overwrite something there? Can it be possible at all? Anyone has any thoughts about?

[ANN] free JPEG library for Palm OS (Last annonce I hope)
I hope this is my last annoncement (I begin to feel like a spammer). I've incremented the version numbers of both libraries. It was necessary to make some correction in the text files to comply with the IJG licencing. If you donloaded the previous version please discard it and download the new version. (The old links are still working but they just gives you a small zip file containing the new links) jcpalm 1.0 is a Jpeg Compression shared library for Palm OS based on the IJG code. It was ported to Palm OS by IDEO, TRG & Harold Howe in 2000 I made some minor corrections in it and, with the permission of Harold Howe, I rebuild it to jcpalm 1.2 The new version can be downloaded from our web site. jcpalm 1.2 Jpeg Compression shared library for Palm OS (source and code): http://www.laubrass.com/doc/PUB/JPEG/jcpalm_lib_1.2.zip Harold Howe's original version of jcpalm can be downloaded from the eyemodule web site: http://www.eyemodule.com/developer/index.asp jdpalm 1.1 is a Jpeg Decompression shared library for Palm OS also based on the IJG code. Harold Howe started to port it to Palm OS but never finished it. With his permission, I have completed the porting. It can also be downloaded from our web site. jdpalm 1.1 Jpeg Decompression shared library for Palm OS (source and code): http://www.laubrass.com/doc/PUB/JPEG/jdpalm_lib_1.1.zip You can use those libraries freely provided that you follow the licencing terms. See jcpalm.txt and jdpalm.txt The bigger difference with jcpalm implementation is that you can compress the image as you get it from the image source (zire 71 camera in my case). You just feed the data line by line to the compressor. That way you don't have to store the full uncompressed image (about 1 meg for a 640x480 picture). A callback gives you the compressed image by chucks of around 16K. It is the same principle for the decompression phase(jdpalm). A callback gives you the decompressed image by chucks of around 16K. You can display it, store it or transmit it as you receive the decompressed image without having to store the full decompressed image. Anyway, if you like it, use it. If you don't... well don't use it. I hope you will like it :) If you find any bug or error, please let me know so that I can make changes and update the library. I would also appreciate your comments. Note: As stated in the license, it is an "AS IS" library. Laubrass and I do not offer any support nor guarantees. Usage is at your own risk and responsability.

I don't use CodeWarrior, so I don't know how to do it, but you should
really made the compiler a bit more relaxed. All the errors are no
errors at all, they could be called warnings but nothing more. The code
will be syntactical correct. You can avoid the error (if you can not
make the compiler more relaxed) doing some casting like:
field = (FieldType *) FrmGetObjectPtr(form, FrmGetObjectIndex(form,
MainNameField));
etc.

Re: 3D Buttons - One more time
Hi Mike, 1. try to convert the picture to grayscale. You will get a nice gray gradient in 8 bit. Set a grayscale palette. 2. Use a better programm, which can downsample images from 24-bit to 8 bit web-palette (or Windows-palette, which I use always) with dithering. 3. Write your own dithering algorithm. 4. Switch to 16-bit mode Regards, Henk Mike Davis wrote: I must not be explaining my problem correctly. I keep getting replies telling me this is in the PILRC docs.

Re: FrmGetObjectPtr compliation error
Those are errors in C++, but not C. C++ has stronger type rules relating to void
pointers. If it were looser, it would be too easy to mess up pointers to objects.

RE: Grimlins
Gremlins will test your application by simulating a crazy user that taps, types, and generally has a good go at crashing your app by excercising the GUI. You can run a single gremlin against a seed number, or multiple ones (known as a horde). The significance of the seed number is that it acts as a seed for a pseudo-random number generator, in turn this can generate a repeatable stream of user events. - Jonathan -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Teresa smith Sent: Tuesday, February 10, 2004 12:44 PM To: Palm Developer Forum Subject: Re: Grimlins Hi, I'm trying to figure out what exactly grimlins do in the Palm Simulator, i've read numerious articles but they don't good understanding of grimlins. would anybody be able able to tell me what there function is.. thanks ___ BT Yahoo!

Silkscreen structure
Hi All,
I am new in palm development and I appreciate if some body answers the
following questions:
1 - When I touch the silk screen, just one x, y is returned by penDown
Event, does this mean that only one sensitive point of silkscreen is touched
or Palm OS selects one point from several points by using an especial
filter.
2 - If several points are touched by pressing finger on silk Screen, is
there any way in CodeWarrior for Palm OS V9, to retrieve the X and Y
locations of all points that have been touched.
3 - Why the FrGet and FrSet functions are wildly used to store and retrieve
global variables in library functions. Isnt it possible to simply save this
values in local static variables like state in the following example :
void MyFunc()
{
static int state = 0;
..
}
Thanks,
Peyman.

RE: 3D Buttons - One more time
PSP is fine for what you're doing, esp if you have < 256 colors. Just reduce the image to 256 colors. If you do it while choosing "nearest Match" you'll see the banding within PSP. This is the same banding that Pilrc will generate. However, PSP also gives you the option when reducing colors to use "error diffusion" reduction method which is another name for dithering. So, choose this in PSP while reducing to 256 colors BEFORE Pilrc gets it's hands on the file and all will be well. You'll see the dithering if you zoom in in PSP, but it'll look great on the Palm screen. If you need to dither a 24 bit image down to 16 bit, you will indeed need another graphics program. But, I've not used a graphics image (as opposed to a photo image) yet that didn't look fine in 256 colors when properly dithered. > -Original Message- > From: [EMAIL PROTECTED] [mailto:bounce-palm- > [EMAIL PROTECTED] On Behalf Of Mike Davis > Sent: Tuesday, February 10, 2004 12:55 PM > To: Palm Developer Forum > Subject: 3D Buttons - One more time > > I must not be explaining my problem correctly.
