RE: Receiving app via Beaming
This bug is fixed in newer versions of the ROM. There was always a workaround. The other DBs were only deleted if the Launcher was active on the other device before you sent the application. So if you exit the launcher on the receiving device before you beam an application to it, the associated database files will not be deleted on any device with any ROM. There was a bug on older ROMs where the launcher would go through its normal logic for deleting an application with all its data if the launcher was active when a copy of an existing application was beamed to it. --- Gavin At 8:00 AM + 4/1/00, Palm Developer Forum digest wrote: Subject: RE: Receiving app via Beaming From: "Fitzpatrick, Joe" [EMAIL PROTECTED] Date: Fri, 31 Mar 2000 20:20:23 -0800 X-Message-Number: 67 I should have read the question more carefully. But, I just tried a quick test and get different results. I just beamed an app from a IIIx (PalmOS 3.3) to a VII. I then beamed some records. Then I beamed the app again. I got an "accept" message box. I answered 'yes', but the records are still there. Is this deleting all DB's with the target creator ID a behavior of 3.0 that was later fixed?

Re: NetLibIFAttach does not work
In your given sample code you get the creator ID into a variable
called "ifCreator" and then you check a variable called "Creator" in
you "if statement"
if(Creator == netIFCreatorPPP)
You probably have another variable called Creator somewhere, but you
want to be checking "ifCreator" in this case.

Hi, Greg, Thanks you for answering the question. I am sorry to accidently
delete your message. Hope you can see this message. Every network settting
are set for PPP default. Actually
First I call err =
NetLibIFAttach(AppNetRefnum,netIFCreatorPPP,ifInstance,AppNetTimeout), if
paased
Next : for (index = 0; 1; index++)
{
err = NetLibIFGet(AppNetRefnum, index, ifCreator,
ifInstance);
if(Creator == netIFCreatorPPP)
break;
}
}
Than: err = NetLibIFSettingSet(AppNetRefnum, ifCreator, ifInstance,
netIFSettingServiceName, Name, buflen);
Thanerr = NetLibOpen(AppNetRefnum, ifErrs);
All above API calls are passed and have no error,( also, ifErrs = 0);
However, the network opened is not the one I attached, but the old one.
I believe another gentalman, Russell Bulmer, post a message "NetLibOpen -
PalmOS 3.1 / 3.3 issues". He has the same problem as mine, except, he did
not attach new one, but try to modify the current setting. (I have try to do
the same thing but failed). If you take a look of his message, you may
have clearer idea.
Thank you.

Re: Palm Beaming to non-palm (windows) IrObex stacks... interoperability issue
John, Attempting to maintain compatibility with Microsoft's definition of "standard" is a challenge. There is some kind of magic undocumented work around for setting hint bits on the Microsoft stack. Perhaps you can get some guru at Counterpoint to fill you in on it. This is your best approach because any change I make to the PalmOS ROM now will only be useful on devices that have not yet shipped. I think there is some magic registry setting that you can use, but I'm not sure about that. I am familiar with the problem that you mention and with the suggested work around. I had intended to make that allowance in the 3.5 release, but it it didn't happen. I'll put it on the list for the next ROM release. The way most developers have been working around Microsoft's lack of support for hint bits is to look for a connection with an OBEX hint bit, but if none is found, just use the first connection you can find anyway. BTW I don't know if Windows 2000 gives you an API for setting the hint bits, but Microsoft decided that they did not want to depend on them anyway. So they devised a new mechanism for discovering devices. This broke compatibility for beaming to all existing PalmOS devices even though we have always supported the standard correctly. We modified our stack in OS 3.5 to deal with the new Microsoft discovery scheme. Microsoft also removed IrComm support in Windows2000, so they also broke our Ir Hotsync support at the same time. Not that I am complaining or anything... ;) --- Gavin At 7:00 AM + 4/11/00, Palm Developer Forum digest wrote: "Schettino, John" [EMAIL PROTECTED] on 04/08/2000 12:07:59 AM As part of HP's CoolTown project (http://cooltown.hp.com) we want to support using VCards and IrObex to support legacy devices. In other words, someone with any kind of device (Palm, CE, Psion, Cell phone, whatever) that supports IrObex and can beam/receive a VCard can interoperate with CoolTown enabled spaces. Problem: The IrObex spec version 1.2, section 6.3 (see http://www.irda.org/standards/pubs/IrOBEX12.pdf, page 44) says "The OBEX IrLMP service hint bit has a value of 0x20 in the second hint byte... Setting the OBEX hint bit is required. Many OBEX clients will not even attempt a connection unless the OBEX hint bit is set." It appears Palm OS (as a client) is following this rule. No hint bit set, no connection attempt. MS Windows's IR Stack does not allow setting the hint bit at all, so when we implemented OBEX on top of the Windows IR stack, a Palm device won't send/receive VCards. Testing: We tested a number of IrObex devices with the MS Windows IR stack + our Obex layer. Psion (Epoc32, REVO) connects Puts VCard OK WinCE (Jornada 4xx, 6xx) connects Puts VCard OK Palm (3.0x, 3.1x, 3.2x, 3.3x, 3.5) fails to connect Using the QuickBeam IrDA stack with its Obex implementation is a work-around, since it sets the hint bit correctly. When using this stack, Palm other devices successfully connect and beam. It seems that testing for the hint bit and not attempting a connection if its not set, although correct in the spec, limits interoperability and doesn't really provide any gain for the user. Suggestion: Either remove the test for the hint bit, or allow users/developers to turn it off ;) Thanks, - John Schettino Hewlett Packard Labs -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palm.com/devzone/mailinglists.html
Re: bitmaps
The Beamer application that is included in the sample source in the 3.5 SDK shows how to create and edit a bitmap on the device. This version supports color bitmaps using the new 3.5 APIs, but will also run on any older device. It includes code to detect the system version and use the correct APIs available in the ROM it is running on. In older ROM versions it supports only 1 bit depth bitmaps. The application can beam itself as well as the bitmaps it creates to other devices. --- Gavin 3.can i create a bitmap in the palm without using the resources functions like FrmNewBitmap and without using any bitmap resource.i want to display them dynamically.is it possible Yes, though you'll have to do some hacking to get it to work on older ROMs (pre-3.5) which don't support the BmpCreate() routine found in Bitmap.h. I believe there was a Handheld Systems Journal article about dynamically creating bitmaps, written by Alan Weiner ([EMAIL PROTECTED]) that would give you the information you need.

Re: Can Palm device access LAN TCP/IP
With windows 2000 (and presumably XP, but I haven't checked), you can click on make a new Connection in the network and Dial-up Connections Panel. Then select the Accept incoming connections option. Next is a dialog showing your connections options. If you have enabled the built in irDA support under win2k, you will see an option for Infrared Port. You can then continue to set up the rest of the connection. If you have a serial port, you can also set up serial connections this way. With windows 98, Irda maps to a comm port. you select that comm port when configuring a PPP server. --- Gavin Do you have any details on setting up a PPP connection over irda between Windows 98/98SE/2k/XP and Palm?

Re: Last cry for help
Ok, I can't resist a last cry for help...
So there is a way to list and select the active network panel
connection. This API has existed ever since OS 2.0 when netlib was
introduced. The API does not allow you add a new network connection,
but you can make an existing one active.
There are a series of launch codes you can send to the network panel.
The launch codes are defined in SystemMgr.h
#define sysSvcLaunchCmdSetServiceID 20
#define sysSvcLaunchCmdGetServiceID 21
#define sysSvcLaunchCmdGetServiceList 22
#define sysSvcLaunchCmdGetServiceInfo 23
I had created a header file that was supposed to be part of the SDK,
but it doesn't look like it was released. Here is the important
information from
NetServiceAPI.h:
#define maxServiceNameLen 32// max length of a service name
typedef UInt32 ServiceIDType;
#define svcNoServiceSelectedID (0)
// serviceListType is the parameter for the
sysSvcLaunchCmdGetServiceList action code
typedef struct
{
Err error;
UInt16 numServices; // number of services available
MemHandle IDListH; // MemHandle to an array of serviceIDs
MemHandle nameListH;
} serviceListType;
typedef serviceListType * serviceListPtr;
// serviceInfoType is the parameter for the
sysSvcLaunchCmdGetServiceInfo action code
typedef struct
{
Err error;
ServiceIDType serviceID; // passed in
to specify service you want info about
UInt32 reserved; // RESERVED -- SET TO ZERO
CharserviceName[maxServiceNameLen]; // returns
name of service
} serviceInfoType;
typedef serviceInfoType * serviceInfoPtr;
sysSvcLauchCmdSetServiceID expects cmdPBD to point to a valid
ServiceIDType value.
You can get the currently active serivce ID value by launching
sysSvcCmdGetServiceID with cmdPBP pointing to a ServiceIDType value
to hold the result.
sysSvcLaunchCmdGetServiceInfo can be used to get the name of a
service by its ID value, cmdPBP must point to a service InfoType
structure.
Finally you can get a list of all available services by ID and name.
This allows you to display a list of available services to the user
and get the service ID of the selected item. CmdPBP is passed with a
serviceListType structure. The structure will return with a number of
services and two memory handles. Your application is responsible for
freeing the handles. The first handle contains a list of numServices
serviceID UInt32 values. The second handle contains a packed list of
numservices null terminated string service names.
you can covert the string list to an array of pointers with the call
SysFormPointerArrayToStrings()
I hope this helps.

re: ExgSend - ExgDisconnect
Both IrDA and Bluetooth Exchange buffer all the data you send and don't actually send anything until the call to ExgDisconnect. The while Ir or Bluetooth transaction happens within the ExgDisconect call. So you need to have enough space available for a copy of what you are sending in order to send it. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
re: MemoPad import/export under Cobalt
MemoPad has always used the same format for multiple text entries (or categories). It uses multi-part mime (rfc2046 multipart/mixed) including support for quoted printable. This will work back to 3.0 devices and continues to be supported on Cobalt. FYI Cobalt also supports ExgGet from the PIM applications. So you can extract data entries. So with Cobalt you can go both ways using the exchange manager. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
