And one more question - do records need to be of a uniform size? Looking at the API it seems that I can put a variable amount of information in a record. Is this true? What if I put a variable size array right in a record? Can I do that? Obviously I'd need to store the size somewhere in the beginning of the record. Records are simply piles of bits. They can be variable length. You define the functions that are called to sort and access the records, so its up to you what form they take.

So why make it a modal dialog? Why not make it a regular dialog? This is not as crazy as it might first sound. On a Windows/Mac/Linux box, there's a huge difference between a modal and a non-modal dialog. The rest of the applications don't get events, the display can be frozen, etc. It seems to me that on a Palm Pilot, the difference to the user is simply the decoration around the box. Alternatively, if it *must* be a modal dialog, try out the preferences dialog on a tungsten (not the OS 5 Simulator which uses the old style). It uses pushbuttons as the tabs, and a listbox of items to select. tap on a pushbutton, and the list changes.

RE: Allocate more than 64K of heap memory
To allocate more than 64k of heap memory, why not just ask for a
very large bitmap, and let the system allocate the memory for you?
myBitmapPtr = BmpCreate ( /* big enough dimensions */ );
if (myBitmapPtr) {
memPtr = BmpGetBits(myBitmapPtr);
// etc.
This seems to work under both OS 4.1 and 5. The system will never
know that you're using bitmap memory for stuff that'll never be
displayed.

Re: Allocate more than 64K of heap memory
Then you should be worried about using this approach on a Palm OS 5.x device. You are creating the chunk, but the system thinks it owns it. At the very least, this means that the system won't clean up after your application after it quits or crashes and you don't free the chunk yourself. But there could be other problems, too, with the system thinking that it owns the chunk and not you. its a potential problem if you dont call free when your app exits :) but, horace isn't going to forget that now is he? :) its a solution that works; its not fool proof.. but, it works *g* i am sure it may need modification at a later date, but, at least you have a function for doing it. when it needs to be changed, we can just change the function. --- Aaron Ardiri [EMAIL PROTECTED] CEO - CTO +46 70 656 1143 Mobile Wizardry http://www.mobilewizardry.com/ -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Re: Re: Idea for a Tungsten App?
Subject: Re: Re: Idea for a Tungsten App? From: Aaron Ardiri [EMAIL PROTECTED] I don't have a Tungsten handy, but I thought I read that holding down the middle button of the 5-way navigator launches the launcher? Well it does, much of the time, but doesn't seem to be quite the same action as pressing the silkscreen button. If the application (usually a game) blocks the hard keys from the system, then this doesn't work any more. Send an e-mail to the game developer telling them they are not Tungsten-T compatible! Ask them when they are going to fix it! we override the 5-way navigator holding down feature in our 3D engine. mainly cause you use the select button to blast your enemies apart. i am sure the % of users being annoyed for the app jumping out to the launcher while trying to frag someone is greater than those wanting to use the 'holding' feature to exit the app :) Perhaps it should be part of the Palm OS UI guidelines: Display and service an [exit] button when your program doesn't support the 5-way exit option.

Does stream on Tungsten?
Hi All,
I've got my code successfully compiling against OS5, and when it's run
checking for the existence of the Sound Stream Feature Set, and then
playing a sampled sound during gameplay in the simulator. This works
like a peach.
The Palm OS 5 documentation I have, however, says that you must check
for the Sound Stream Feature Set using this code:
UInt32 version;
Err err;
err = FtrGet(sysFileCSoundMgr, sndFtrIDVersion, version);
if (err) {
// Sound Stream Feature Set not present
if (err == ftrErrNoSuchFeature) {
FrmCustomAlert(errAlert,No Stream Manager., , );
} else {
FrmCustomAlert(errAlert,Some other problem!, , );
}
} else {
// The Sound Stream Feature Set is present.
FrmCustomAlert(errAlert,It's here., , );
}
On the simulator, I get 'It's here.'. On the real Tungsten/T, I get No
Stream Manager errors.
Anyone else see this behavior? What's the right thing to check
for...OS5?
Anyone know?
-Ken

In both of your examples, I got the direct muls version, not the __lmul__ version.

Re: Convert Palm App to WindowsCE App
Chris, Very interesting. Thanks. In comparison to appforge, it costs around the same for the dev system, depending on specials and competitive upgrades. It's runtime costs $70 verses free for palm and $10 for PPC per install. It uses C language as it's true programming language vs VB. It has many more tools in it's IDE that are not in a CW or MS Visual IDE (appforge uses MS VB for it's IDE) to assist in RAD. It's very nice and targets more platforms (namely, WIN 32, for laptops, tablets, etc.). It has a nicer way of using the screen configurations of the different devices in one project - Very nice feature. Thanks, now the decision is getting harder. Any more multiplatform dev systems?

Re: Modal Form without a frame?
I've never used LstPopupList(), but I don't suspect it can handle list items that are both bitmaps and labels, though please correct me if I'm wrong. It you do an custom drawing routine for your list, you can put whatever you want in as the list items. You will be limited to the space the OS allocates for each visible item, but if you can live with an 12 pixel height per item, then its a good solution, especially if you have less than 11 items to pick from and thererfore can avoid the scroll arrows. -- Ben Combee [EMAIL PROTECTED] CodeWarrior for Palm OS technical lead Palm OS programming help @ www.palmoswerks.com -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Re: Convert Palm App to WindowsCE App
The recent Java thread on Palm and PPC targeting, as with old threads, didn't come up with any conclusive opinions of paths that lead to the ability of a single source compiling to the different platforms for Java. I think the problem here is no common IDE for Java that targets the Palm and PPC. CodeWarrior Wireless Studio, PDA Edition, supports J2ME programming, including support for Sun's JVM on Palm OS, and several of the VM's on Pocket PC. We've not pushed it very much for Java development on Palm OS, due to the limitations of 68K-based Java virtual machines, but it does work, and it supplies a RAD environment for J2ME development, while using a common IDE with the CodeWarrior for Palm OS tools. -- Ben Combee [EMAIL PROTECTED] CodeWarrior for Palm OS technical lead Palm OS programming help @ www.palmoswerks.com -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Differences Simulator/Tungsten?
Hello! I have received numerous reports from owners of Tungsten T and NX70V devices that my gaming framework crashes their devices. I do not own a real device, but use the Simulators (Palm Release and Debug, Sony Clie Release). Even the Debug simulator reports no problems with my code (not even a direct screen access or anything). Is there anything that is more true to the original? Ben Combee mentioned a Tungsten simulator for members of the PluggedIn program, but since I am not a hardware developer I am not going to get it :-(( I only use OS functionality in the application in question. The only exception being a conversion of a bitmap from V2 to V3 (the intention here is to enable the use of the same hires bitmap resources on Sony Clie and OS5). For this I use the same procedure as the BitmapRsc1 sample code does. Any help will be greatly appreciated. If some kind soul with a working debugger and an OS5 device could download the framework at www.tilo-christ.de/razor and pinpoint the location of the crash this would be highly appreciated.

Cold boot on Tungsten/T doesn't reset everything
I've gotten my /T into a knot that cold boot doesn't reset. Used to be that I could go to console mode, import some files, start debugging mode, crash, reset, and restart debugging mode. Now, even if I don't run my crashing software, I have to cold boot every time to get to debugging mode. I'm using PalmDebugger V3.6d7 and a serial cradle. I've tried to run the battery down to nothing, but that doesn't change anything. I'm about to try opening the case to disconnect the battery for a while in hopes that lack of power will reset whatever the problem is. I suppose I could send it in for warranty repair, but if the problem is my software, then it'll just happen again. Any advise (don't write buggy software?) would be appreciated. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
Re: Convert Codepage 932 (Japanese) to Unicode
Be aware. Once CP932, always CP932...even in UTF-8. The UTF8 bytecode is a representation of the character in CP932. Don't expect that you can go from CP932 to UTF8 to EUC_JP. Ain't goin' to happen. Check out a program called JCode. It might help you. I'm running into the problem where Linux/Unix is not totally CP932 capable. I represent everything as UTF-8...So, all's ok. But, I can't expect to convert UTF-8 to CP932 on Unix. That ain't going to work either. The PALM handheld is EUC_JP (I'm pretty posstive of that). When I enter japanse on the handheld, sometimes Windows has a problem because the character is not in the default CP932 character set (get's converted to ?'s). Sometimes this happensI am working on this problem. May be implementing JCode in my conduits (I write in Java/Unicode conduits). I explicitely write specify the character set on each of my palms (Japanese, Chinese, Latin, Korean, etc.)...so, if you're using Java, then you're set...
