Re: How to draw low density bmp on high density display?
Hi, The problem is I dont want to ship databases with bitmap families, but rather display bitmap as is so that 1pix in bitmap is rendered to exactly 1phisical devise pixel. What I experience and try to avoid is scaling the bitmap on high-density displays! I tried WinSetScalingMode(kBitmapScalingOff); I tried WinSetCoordinateSystem(kDensityDouble/ kDensityLow); I tried BmpCreateBitmapV3(pBmpV1, kDensityDouble/ kDensityLow, BmpGetBits(pBmpV1)...); I tried WinCreateOffscreenWindow(...nativeFormat/ screenFormat); Nothing worked as targetted. What I need is effect of drawing bitmap (BitmapTypeV3) with kDensityDouble. Thanks!

RE: FrmGetObjectIndex problem
Older OS (pre 3.something) FrmGetObjectIndex() would fatal if the object was
not found!
Check the OS version and if it's an early one that crashes instead of
returning an error, patch the FrmGetObjectIndex() trap a local function.
Example:
// generalized structure that matches the pre OS4 structures
typedef struct
{
//WindowTypewindow; // the old
WindowType struct was 40 bytes long
UInt8 window[40];
UInt16 formId;
//FormAttrType attr; // the old
FormAttrType struct was a UInt32
UInt32 attr;
//WinHandle bitsBehindForm;
void * bitsBehindForm;
//FormEventHandlerType *handler;
void * handler;
UInt16 focus;
UInt16 defaultButton;
UInt16 helpRscId;
UInt16 menuRscId;
UInt16 numObjects;
//FormObjListType * objects;
struct PrvFormObjList
{
//FormObjectKindobjectType;
UInt8 objectType;
UInt8 reserved;
//FormObjectTypeobject;
union
{
void*ptr;
} object;
} *objects;

Subject: FrmGetObjectIndex problem
Hi all,
I got a form with some dynamically created objects.
When I use FrmGetObjectIndex in TT (and os5 simurator), when there are no
such object ID (the object doesn't exist), it will return frmInvalidObjectId
(equal = -1).
But when I do the same things in Clie N610 (which is os4), it will return
65535.
Finally, if I ran the program in Palm V (os3.2), it will return an fatal
error said the object doesn't exist.
I want to use FrmGetObjectIndex to see if the object exist, is there any way
to do it in all different version of palmos?
Thank's for your advice.
Geoffrey

VFS Fragmentation?
I have a 16MB SD card that I've filled with 3 megs of data, stored in 1082 files. Using my cardreader on a Windows box, the card does contain exactly 1082 files, which consume around 3 megs of space. However if I place this exact same card into my Palm m515 and do Card Info, it reports 0 free bytes, 14.1 MB used. Am I hitting fragmentation due to the # of files here? Is there a defrag algorithm I can incorporate? This is just a VFAT volume, no? I'm attaching more details below. Your help is much appreciated! --- DETIALS --- I am taking a 3-meg PDB of about 3000 records, and writing it in a proprietary fashion to a VFS volume. Specifically, I create a directory that represents the name of the PDB: /PALM/Programs/MyCompany/MyApp/MyAppData.pdb/ Then, each record of the PDB is stored as an individual file in that directory. So if I want to read record #63(0x3F) out of the PDB 'MyAppData.pdb', I simply read the following file: /PALM/Programs/MyCompany/MyApp/MyAppData.pdb/003F I have run into some strangeness, and I wonder if it's a VFAT fragmentation issue. My C++ SyngMgr calls to VFSFileWrite() started returning vfsErrVolumeFull unexpectedly. I say unexpectedly because there is only about 3 megs of data on this 16-meg card, stored in 1082 (veyr small) files. If I copy the contents to my Windows desktop using a cardreader, Windows reports there being only about 3 megs of data.

Re: nilEvent Timing
Edan, >I force nil events to happen so I can get accurate timing. My point is that not every nilEvent will necessarily be because of EvtSetNullEventTick() or a timeout. So you may still end up with *extra* nilEvents, which may or may not impact what you are trying to do. I don't know all the other conditions which can cause nilEvents, but one example is having the insertion point enabled in a field object. The OS causes the extra nilEvents, and then uses them to show / hide the flashing insertion point.

Re: stack overflow error
Those are system functions apparently called in reaction to the redraw event. They are similar to your functions and share the same stack. Hence they also take away some space on the stack and you have to program the way that you allow them to do so. While it is true that nobody will tell you how much space these functions take, you can be pretty sure that it is not too much. (For sure more than 500 By.) So if you have the critical situation, do not care about these function. Care about you functions that are in the call sequence (CW shows them all). If you can't judge the result from CW, then take a piece of paper and wrote down their names. Then set the stack pragma to a low value and compile these functions. Compiler will tell you how much stack space do they need. - Original Message - From: <[EMAIL PROTECTED]> To: "Palm Developer Forum" <[EMAIL PROTECTED]> Sent: Monday, August 23, 2004 4:29 PM Subject: Re: stack overflow error > OK, I have identified the functions that are causing the stack overflow.

I'm using CW 9.3 on Windows 2000 and the T3 is running an application built on Palm OS 5.3 Thanks in advance, Lorraine -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

I'm using the eclipse stuff from this site. Even the simplest stuff is failing - My problems are as follows: 1) The Garnet simulator doesn't work when I call BmpCreate. The header is written 16 bytes away from the returned pointer and the bitmap itself is not refreshed to white - this is not the documented result - and the simulator also crashes when I try to write to the bitmap data. BmpCreate does work. However, on Palm OS 5, you can't directly access the data structures used by the OS. Instead, you should use the SDK and glue library calls (BmpGlue.h and Bitmap.h) to handle accessing this data. 2) After giving up on the simulator, I find that the emulator works as expected - even the debugger returns accurate results. The problem here is, I can't get the emulator to use the skins, the handspring site appears to have disappeared and all the generic skins are monochrome emulations. The emulator also doesn't have an OS 5 ROM with it. I suppose the question is, how do I set up a good debug environment for a low density palm OS 5 device in 65536 colours? The Palm OS Emulator can't emulate an OS 5 device. It can only emulate 68K-based devices. For a 16-bit color, low-density device, you need to get a ROM image for a m505 or equivalent. These are available from the developer program at http://www.palmsource.com/developers/ If you're doing game development, especially for Palm OS 5, you might want to look at using a library like Razor or GapiDraw. See http://flippinbits.com/twiki/bin/view/Main/DevelopmentToolsList for a good list of tools and libraries. -- Ben Combee, DTS technical lead, PalmSource, Inc.

How to draw low density bmp on high density display?
Hi group, I have a low density bitmap I wish to draw on high density display without being scaled. Can anyone tell me how is this done? I tried: WinSetScalingMode (kBitmapScalingOff); WinDrawBitmap(bmpP, x, y); but this has none effect ?! When the bitmap uses version3 bmp format, the blitter properly selects high-density bitmap and renders it as I wish. So, how can a 160x160 pix bitmap be rendered on left top portion of the screen on high density display devices? Thanks!

Re: nilEvent Timing
Greg / Geoff, >You don't normally get a nilEvent unless you call EvtGetEvent() with a >finite timeout value That is not necessarily true, you can get them under other conditions as well. What is true is that the above is one of the reasons a nilEvent may occur. For example, if there is a field object with the focus you will notice there are nilEvents which coincide with the flashing of the insertion point, assuming the insertion point is not disabled. >If you call EvtGetEvent() with a timeout of, say, 10 ticks, and it >returns a nilEvent, you know that you're getting the event exactly 10 ticks >after making the call. No, you don't know that. You know that it is not more than about 10 ticks after making the call. It is possible to be seeing a nilEvent due to something else earlier than that. It should also be pointed out that the nilEvent won't occur in another event appears in the queue first, so this doesn't make for a way to guarantee smooth animations. >The typical way of getting something to happen exactly when you want it to is: As Chris mentioned, I'd suggest looking at the source to reptiods.

re: SD Card slot
Try this: when you receive the notification you simply preempt the OS by setting the
application switching as already handled.
In StarterPalmMain:
switch (cmd) {
case sysAppLaunchCmdNotify:
if ( notifyP->notifyType==sysNotifyVolumeMountedEvent )
notifyP->handled = vfsHandledUIAppSwitch | vfsHandledStartPrc;
break;
}

RE: Unicode
If you want the converted string in any of the formats other than UTF-8, UCS-2, UTF-16LE, or UTF-16BE, you have to do the conversion yourself.

re: DmFindRecordByID error
Ok, I've solved my own problem. It seems that a record may have a unique ID with a maximum of 24 bits (i.e. 16777215), despite passing in a UInt32. So annoying...and the only place in the documentation to find it is by looking at the SortRecordInfoType structure to find that the uniqueID is an array of 3 UInt8 objects. - Kyle -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
