Re: Last cry for help
My software currently uses the serviceListType stucture from NetServiceAPI.h
(not published) but it appears to have changed in the Garnet 4.5.7 OS release
an later (I'm using a TREO650) Does anyone know what the new struct looks like?
Old Struct
// 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;

Can you solve the mystery of the missing NetServiceAPI library? I've scoured the palmos.com web site and I can't find it. I've even found dead links to knowledge base articles about it. Has Palm upgraded it to support new OS versions? Is there a version which supports removing a network service?

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.

Ralph, I think I can explain what's going on. There's two different systems within the Palm OS that need to be configured. The first is the connection panel. This can be straightforwardly updated using the Cnc* functions defined by the Connection Manager. According to my copy of the documentation these were created in the new OS 4.0. The second system is the network panel. As I understand it there's a network database that holds a list of services and their configurations, and possibly other databases as well. Somewhere there is also a database which stores information about the currently selected network service. The biggest difficulty is that the network stack is running in the only other thread on the device. There's no official way of notifying that other thread that the databases have changed. Another difficulty is that the network system and its data formats have changed several times over the last few versions of the Palm OS. Palm Developer Technical Support once made available the NetServiceAPI, an /unsupported/ library which gives you the ability to create network services, modify network services, and set the current active service. I believe that they no longer make this available because it has not been updated to support the newest versions of the Palm OS. Without this library, I don't think there is any way to do what you want. I suggest that you join the Palm OS Developer Program and get an Advantage Level Membership. http://www.palmos.com/dev/programs/pdp/index.html Then you can submit your request to them as a developer support incident. Perhaps they can provide an updated version of the NetServiceAPI library. If you do join, please let me know what they say.
