re: Negative Numbers in Numeric Fields - a Solution
I thought that this was a great solution, but I now find an unfortunate side effect. When users use the popup keyboard to enter numbers into a numeric field, they cannot enter the minus sign. Since the field is set to numeric, the Palm OS blocks the minus sign, and in this case I do not have the option of trapping the key input because I no longer get the keyDownEvent. After all of these years, why does Palm still not realize that some numbers are negative !!!

Negative Numbers in Numeric Fields - a Solution
I have been searching for an elegant solution to allow negative number input into fields and tables. I initially simply set these fields to text fields. That was an acceptable workaround until the availability of keyboard based devices such as the Treo. With this workaround, the numeric input shift is not automatically selected when the user selects one of these fields (or table cells). I finally found a reasonable solution and I wanted to document it here in case there were others that were still struggling with the problem. First, set the field attributes to numeric. For tables this is done using FldGetAttributes & FldSetAttributes in the load procedurre that you specified with TblSetLoadDataProcedure (this is where I also set the editable, underlined and autoShift attributes). Next, provide a keyDownEvent handler that looks for a minus sign and simply pastes it into the field using FldInsert. I also check that the field in focus (FrmGetFocus) is the desired field, and that FldGetInsPtPos returns 0. For tables, the object in focus is the table, so I further check the row and/or column (TblGetSelection & TblGetCurrentField). I actually wrapped all of this up into a function (called from the keyDownEvent handler) that checks a range of fields and/or table columns.

Strange Field Behaviour
I have seen some strange field behaviour on the E2 simulator. I have not seen the same behavious on OS4. I have not yet tried other OS versions to isolate when it started happening. The behaviour only happens on fields with autoshift disabled. When you tap in the middle of the text in a field, you expect the cursor to be placed where you tapped. This works ok for fields with autoshift enabled, but on fields where autoshift is disabled, the cursor hops to the end of the text. A subsequent tap in the same field will position the cursor properly. I tried this even on forms where I do not do any processing of field events, so I do not believe that it is a problem within my application. I tried other applications on the E2 simulator, and while they do not exhibit exactly the same behaviour, they all do something weird on fields that have autoshift disabled.

Exchange Manager Problems on Cobalt
My application uses the exchange manager to transfer text
files to the MemoPad application. On Cobalt it causes the
simulator to crash (after I have tapped the OK button to
accept the data into MemoPad). I have reduced the transfer
code down to a bare miniumum to see what is wrong, but it
still fails all the time:
ExgSocketType exgSocket;
MemSet(&exgSocket, sizeof(exgSocket), 0);
exgSocket.noStatus = 1;
exgSocket.noGoTo = 1;
exgSocket.localMode = 1;
exgSocket.description = "Testing";
exgSocket.target = sysFileCMemo;
exgSocket.name = "Memos.txt";
Char *textBuf= "** Testing **";
Err error = ExgPut(&exgSocket);
if (error == 0)
{
ExgSend(&exgSocket, textBuf, StrLen(textBuf) + 1, &error);
ExgDisconnect(&exgSocket, error);
}
This works reliably on everything except the Cobalt
simulator. Any ideas?

Re: Basic 68K UI not working on Cobalt Simulator
I would like to add my vote that this is a bug that needs to be
fixed.
I also allow the user to switch between a set of initialized forms
while retaining the values on the form. Of course it would be
possible to rewrite the application to treat each form
individually and maintain a shadow database entry for each
form, but it would be a significant amount of work, and the
performance on older devices would suffer.

Re: Unreliable nilEvents on Cobalt
In my case I am not using nilEvents for timing, just for background processing. I ask for another nilEvent as soon as I have finished processing one. The intent is to process as quickly as possible in the background, but keep the door open for other events (such as a "Cancel" button). If I use any other method for posting an event, it goes to the head of the queue and blocks the other events I am waiting for.

Re: Unreliable nilEvents on Cobalt
There has been a lot of discussion regarding EvtSetNullEventTick, and I thought that the conclusion was that the earlier documentation was wrong. The latest document says that the parameter is "The time, in ticks, since the last reset by which a nilEvent is to be added to the queue." This is the way that it seems to be working - by setting the parameter to TimGetTicks, I get another nilEvent immediately. The only problem is that with Cobalt sometimes a nilEvent does not get generated.

Unreliable nilEvents on Cobalt
I use nilEvents to do some background processing in my application. This has worked ok so far, but is not reliable on Cobalt. After processing the nilEvent, I immediately generate another nilEvent using: EvtSetNullEventTick(TimGetTicks()); I do this repetitively until the processing is complete. On Cobalt, I regularly miss nilEvents. I can reduce the problem by adding a delay: EvtSetNullEventTick(TimGetTicks() + delayTicks); By increasing delayTicks I can reduce the likelyhood of missing nilEvents, but this obviously slows down the background processing. Is this a bug in Cobalt? Laurie -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/

Form Problems on Cobalt
I have implemented a tabbed database edit screen for may application. It has worked properly since OS version 2.0, but it no longer works on Cobalt. The user launches the database edit screen(s) via a menu item. In the frmOpenEvent handler I initialize the other forms using FrmInitForm. I also update the fields on all forms at this time. When the user taps one of the tab buttons, I display the required form by using FrmSetActiveForm and FrmDrawForm. When the OK button on any of the forms is tapped, I write all of the data from all of the forms to the database file and then close all of the forms by calling FrmEraseForm and FrmDeleteForm. On Cobalt, none of the forms appear. Cobalt appears to handle form drawing quite differently. On earlier versions of the OS, the form is drawn as soon as FrmDrawForm is called in the frmOpenEvent handler. On Cobalt, the form is not drawn until the next call to EvtGetEvent. It appears that if other forms are initialized (via FrmInitForm) in the frmOpenEvent handler, nothing is drawn. Any Suggestions?

Re: How to stop fields from writing over a menu?
I solved the problem in my application in the following way.
I use the nilEvent to update some fields dynamically. This was
causing a problem when the menu was opened on top of
the fields. I simply changed the code in the nilEvent to only
update the fields when the main form was the active form:
if (FormPtr(WinGetActiveWindow()) == frmPtr)
{
}

VFSFileRead and Simulator
I am having a problem with the VFSFileRead function on the Simulator. Whenever I try to read a file, the read stops after 4092 bytes. I get an error code of 7197.

Is there an Arm version of Mathlib?
I asked this question once before without a response, so I will try once again. I was wondering if there was a version of Mathlib that had been compiled for the Arm processor. For applications with a lot of floating point calculations I assume that a native version of Mathlib would be significantly faster.

Re: Fast Database Search
I have used a binary search whenever it was possible. The search that I am currently trying to perform is on data that cannot be sorted. I need to do a calculation on data that is in the database to see if it meets the criteria. I cannot do any pre-calculations since I do not know what the search criteria will be beforehand. My suspicion is that I am stuck with the linear search, but I was hoping that someone had come up with something clever. You could presumably bypass the database routines and index through the database, but that would probably be extremely dangerous. It would be very nice if the OS provided a routine to search the entire database for a match based on a user defined callback routine (such as is done for the sorting routines).

Fast Database Search
Does anyone know of a fast way to search through a very large database (17000 records)?
I currently use the the standard approach:
for (UInt16 recordNum = 0; recordNum < DmNumRecords(db); recordNum++)
{
MemHandle dbRecordHandle = DmQueryRecord(db, recordNum);
MemPtr dbRecordPtr = MemHandleLock(dbRecordHandle);
... check if data matches search criterion
MemHandleUnlock(dbRecordHandle);
}
This takes about 20 seconds.
I have successfully used DmFindSortPosition when looking for data that is sorted, but I
cannot think of any way to speed up the search for other data.
Any ideas?

Graphical Buttons - solution
I started a thread a few weeks ago in an attempt to find a good way to provide
graphical buttons that worked on color devices and was backwards compatible with
Palm OS 3.0. I have found a solution that seems to work.
Palm OS has a graphical button that works great, but is only available on OS
versions 3.5 and later.
The usual way to provide graphical buttons that work on OS versions prior to 3.5
is to overlay a bitmap with a button (without a label). This works fine on black
and white devices, but the button does not highlight in the right colors on color
devices.
The best solution proposed for color devices was to create a font with the
appropriate bitmaps and use the custom font for the button label. There are two
drawbacks to this solution. Constructor does not allow you to specify custom
fonts for button labels. PilRC allows this, but I did not want to convert all of
my application from Constructor to PilRC. This option also does not allow you to
take advantage of some of the features of graphical buttons such as a different
bitmap for the selected state.
The solution I have come up with is as follows. Start with the bitmap and a
regular button overlay. On top of this overlay a graphical button with the bitmap
set to the same bitmap. Set the usable bit for the graphical bitmap to false.
In the frmOpenEvent of the form do a simple check of the OS version, and if it
is version 3.5 or later, show the graphical button. This solution works on OS
versions prior to 3.5 (the graphical button is hidden) and supports full graphical
buttons on OS version 3.5 and later (the graphic button is shown).
Code snippets:
At application start:
// get the ROM version
const UInt32 rom35Version = 0x03503000;
UInt32 RomVersion = 0;
FtrGet(sysFtrCreator, sysFtrNumROMVersion, & RomVersion); // update RomVersion
Form event handler:
Boolean FormHandleEvent(EventPtr eventPtr)
{
FormPtr frmPtr = FrmGetActiveForm();
switch (eventPtr->eType)
{
case frmOpenEvent:
if (RomVersion >= rom35Version)
FrmShowObject(frmPtr, FrmGetObjectIndex(frmPtr, GraphicButton));
...
break;
...
case ctlSelectEvent:
switch (eventPtr->data.ctlEnter.controlID)
{
case RegularButton:
case GraphicButton:
// process button press (common to both buttons)
break;
...
}
}
}

I was not the person interested in rectangular frames. I picked up this thread when I realized that using a custom button font could be a solution to the problem of proper button highlighting on color Palms. I was looking for a solution that was compatible with OS3.0. The usual method of overlaying a bitmap with a button works ok in black and white, but does not highlight properly in color. The conclusion so far seems to be that this is possible with PilRC, but there is no way when using Constructor to specify a custom font for a button. Since I already have a significant number of resources defined using Constructor I was hoping to avoid a wholesale conversion of everything to PilRC. After a quick look at PilRC my conclusion is that it is more powerful than Constructor, but not as user friendly.

Re: Rectangle Button Frame

Unfortunately my application is quite large (32 forms, and most of them are very complicated) and I would prefer to avoid having to change everything over to PilRC.

Graphic Buttons
I use a number of graphic buttons in my application. Since I want to preserve compatibility with Palm OS version 3.0, rather than use the built in graphic button capability, I put a button with no label over a bitmap graphic. This works fine, but has some subtle side effects on color displays. On a color display a normal button highlights by turning the normally white background blue.

I don't understand what these are for 62048.611 (63237): -> EvtAddEventToQueue: ctlSelectEvent ID: 12004 On: 0 62048.611 (63237): <- EvtGetEvent: ctlSelectEvent ID: 12004 On: 0 makes sense, pen must have been lifted, and the ok button was selected 62048.722 (63237): -> EvtAddEventToQueue: frmUpdateEventID: 1500 makes sense, this is a call to FrmUpdateForm 62048.842 (63237): <- EvtGetEvent: winExitEventEnter: 4AB4 Exit: 5AA6 Enter Form: "Flight Plan" 62048.842 (63237): <- EvtGetEvent: winEnterEvent Enter: 4AB4 Exit: 5AA6 Enter Form: "Flight Plan" makes sense, the old form is gone, and the new form is in place 62048.852 (63237): <- EvtGetEvent: frmUpdateEventID: 1500 makes sense, the update event generated by my call to FrmUpdateFrom 62049.042 (63237): <- EvtGetSysEvent: penUpEvent X:9 Y:142 62049.042 (63237): <- EvtGetEvent: penUpEvent X:9 Y:142 this is where I get really confused. It appears that this is the pen up that resulted in the ctlSelectEvent (the ok button on the previous form). I am surprised that this event is generated since I would have assumed that the pen up would have been handled by the system when it was tracking the pen before it generated the ctlSelectEvent. 62049.052 (63238): -> EvtEnqueueKey: ascii = 0x00F9, keycode = 0x, modifiers = 0x. 62049.052 (63239): <- EvtGetSysEvent: keyDownEventKey:0xF9, Modifiers: 0x 62049.052 (63239): <- EvtGetEvent: keyDownEventKey:0xF9, Modifiers: 0x the penUpEvent results in a keyDownEvent being generated on the new form 62049.132 (63239): === ERROR: * 62049.132 (63239): === ERROR: ... SysFatalAlert with the message: "Table.c, Line:94, Text not usable". 62049.132 (63239): === ERROR: * This does not normally cause a problem, but after 2.7 million gremlins, this problem occurred.

Re: This target is not registered
I got rid of my problem with Palm OS 3.0 by creating a new emulator session. There is a possibility that the session that I was trying to use was created with an earlier version of the emulator and/or CodeWarrior. I thought that I had tried creating a new session, but maybe I didn't.

This target is not registered
I can use CodeWarrior & POSE to debug on PalmOS 4.0 and 3.5. When I try to use PalmOS 3.0 I get the message "This target is not registered" when I try to debug.

External Memory
I'm having trouble understanding how external memory should be used. I would
like to have the option of moving some of my very large database files onto
external memory (expansion cards). My startup code is the standard:
dbHandle = DmOpenDatabaseByTypeCreator(dbType, creator, dmModeReadWrite);
if (dbHandle == 0)
{
// the database does not exist, create it now
DmCreateDatabase(0, dbName, creator, dbType, false);
// open the newly created database
dbHandle = DmOpenDatabaseByTypeCreator(dbType, creator,
dmModeReadWrite);
}
// get the localID and card number of the database
LocalID localID;
UInt16 cardNo;
DmOpenDatabaseInfo(dbHandle, &localID, NULL, NULL, &cardNo, NULL);
// get the attributes and the version number
UInt16 version, attributes;
DmDatabaseInfo(cardNo, localID, NULL, &attributes, &version, NULL, NULL,
NULL, NULL, NULL, NULL, NULL, NULL);
...
My assumption was that when you initially open a database,
DmOpenDatabaseByTypeCreator would find the database even if it is not on
card 0. If a database is NOT found on external memory, DmCreateDatabase
would create it on card 0, but if there was one on another card, the first
DmOpenDatabaseByTypeCreator should find it.
I do not have a real external memory card to test this on, but have
simulated external memory using HostFS and POSE. Using DigiBrowse I can see
that the database is in external memory and that it has been removed from
main memory. The bottom line is that the first DmOpenDatabaseByTypeCreator
does not find the database on external memory.
Help,
Laurie
